What is the Deadline for Submitting Self-Assessment Tax Returns for 2023-24?

An Overview of the UK Self-Assessment Tax System and Deadlines for the 2023-2024 Tax Year

The UK’s Self-Assessment tax system is a process used by HM Revenue and Customs (HMRC) to collect Income Tax. While most individuals in the UK are taxed automatically through the Pay As You Earn (PAYE) system, some need to complete a Self-Assessment tax return to declare any additional income or claim tax reliefs. This system applies mainly to those who are self-employed, business owners, and individuals with additional untaxed income such as property rental or foreign income.


What is the Deadline for Submitting Self-Assessment Tax Returns for 2023-24


For the 2023-2024 tax year, the process and deadlines remain similar to previous years but with a few updated guidelines for taxpayers. As the tax year runs from 6 April 2023 to 5 April 2024, it is crucial to understand the timeline for notifying HMRC, submitting tax returns, and making payments to avoid penalties.


Who Needs to Submit a Self-Assessment Tax Return?

While not all individuals in the UK need to complete a Self-Assessment tax return, there are specific groups for whom this is mandatory. If you fall into any of the following categories, you must submit a return:


  • Self-employed individuals or sole traders: If you earned more than £1,000 from self-employment during the tax year, you are required to submit a return.

  • Business partners: If you are in a business partnership, both you and your partners need to submit a tax return.

  • Company directors: Unless the income is solely from the PAYE system.

  • Individuals with untaxed income: This includes income from rental properties, investments, savings, or foreign income.

  • High earners: If your income exceeds £100,000 per year, regardless of the source, you will need to file a tax return.

  • Those claiming certain tax reliefs: For example, if you’re claiming higher-rate tax relief on pension contributions or charitable donations.


If you are unsure whether you need to submit a return, HMRC provides an online tool that helps determine whether Self-Assessment applies to you. Not informing HMRC of your requirement to file a return can result in penalties.


Key Deadlines for the 2023-2024 Tax Year

Deadlines are a critical part of the Self-Assessment process. The following key dates should be kept in mind to avoid penalties:


  1. 5 October 2024: This is the deadline for notifying HMRC if you need to submit a tax return. If you are required to file but have not done so before, you must register by this date.

  2. 31 October 2024: For individuals submitting their tax returns on paper, this is the deadline for filing. Paper returns must be completed and submitted by midnight on this date.

  3. 31 January 2025: For those submitting online tax returns, this is the final deadline. All online returns must be filed by midnight on this date. Additionally, if you owe any tax, this is also the deadline for payment.

  4. 31 July 2025: If you are required to make payments on account (advance payments towards your tax bill), this is the deadline for the second payment. Payments on account are typically required if your tax bill exceeds £1,000.


The most important deadlines to remember are for submitting your tax return and paying any tax owed by 31 January 2025. Missing this deadline may result in penalties and interest, which we will discuss later in this article.


Penalties for Missing Deadlines

Failing to submit your Self-Assessment tax return or pay the tax you owe on time can result in penalties. HMRC imposes penalties based on the length of the delay and the amount of tax owed. Here’s a breakdown of the common penalties for late filing:


  • 1 day late: An automatic penalty of £100 will be applied if your return is late, even if no tax is owed.

  • 3 months late: An additional daily penalty of £10 per day will be charged for up to 90 days (a maximum of £900).

  • 6 months late: A further penalty of 5% of the tax due or £300 (whichever is greater) will be imposed.

  • 12 months late: An additional 5% of the tax due or £300 (whichever is greater) will be charged.


In addition to these penalties, interest will accrue on any unpaid tax. This means that even if you file your return but fail to pay your tax bill, you will incur interest charges until the outstanding amount is settled.


How to Avoid Penalties

To avoid penalties, it is essential to submit your tax return and pay your tax on time. HMRC provides a range of support for individuals who may struggle with filing or payment, including:


  • Provisional Figures: If you are unable to determine your exact income before the deadline, you can submit a return using provisional figures and amend it later.

  • Appealing Penalties: If you miss a deadline due to circumstances beyond your control, such as illness or bereavement, you can appeal a penalty with HMRC. In some cases, HMRC may waive penalties if you have a reasonable excuse.

  • Time to Pay Arrangements: If you cannot pay your tax bill in full, HMRC may offer a payment plan that allows you to spread the cost over a period of time.


By understanding the deadlines and being proactive about submitting your return, you can avoid unnecessary penalties and interest.


Methods of Submission: Online vs Paper

There are two primary ways to submit your Self-Assessment tax return: online or by paper. The online method is generally preferred for its ease of use, faster processing times, and immediate confirmation of submission. Filing online also gives you until 31 January 2025 to submit, while paper returns must be filed by 31 October 2024.


  • Online Submission: The online process involves registering with HMRC’s Government Gateway, filling out your return via the Self-Assessment portal, and submitting it electronically. You can save and return to your return at any time before submission, making it a flexible option.

  • Paper Submission: Paper returns must be requested from HMRC (form SA100) and manually completed. After submission, HMRC will send you an acknowledgment letter confirming receipt of your return. It’s essential to send your return well in advance of the 31 October deadline to ensure it is received on time.


Where to send paper forms:

If you live in the UK, you can send completed paper forms to:

Self Assessment

HM Revenue and Customs

BX9 1AS


If you live outside the UK, you can send completed paper forms to:


HM Revenue and Customs

Benton Park View

Newcastle Upon Tyne

NE98 1ZZ

United Kingdom


HMRC encourages individuals to file online where possible due to the convenience and extended deadline.


The UK Self-Assessment tax system is designed to ensure that individuals and businesses with additional or untaxed income accurately report their earnings. With key deadlines approaching in the 2023-2024 tax year, understanding your obligations to HMRC is critical. Missing a deadline can result in costly penalties, but with proper preparation and awareness, these can be easily avoided.



Payment of Self-Assessment Tax, Refunds, and What to Do in Case of Errors

In the previous part, we explored the UK Self-Assessment tax system and its deadlines for the 2023-2024 tax year. This section will take a closer look at how to manage payments, including the different payment options available, how to request a refund if you’ve overpaid, and what to do if you realize there’s been an error in your tax return. We'll explain each section in detail and offer examples to help clarify common scenarios that taxpayers may face.


Paying Your Self-Assessment Tax Bill: Options and Procedures

Once you have submitted your tax return, the next critical step is to pay any tax that you owe. The payment deadline for the 2023-2024 tax year is 31 January 2025, and it's essential to make sure that HMRC receives the correct payment by this date to avoid interest charges or penalties.


Payment Options

HMRC provides a variety of payment methods to ensure flexibility and ease for taxpayers. Depending on your preference, you can pay by:


  1. Direct Debit: One of the most popular methods, direct debit allows you to set up an automatic payment from your bank account. This option ensures that you don't miss the deadline, as HMRC will withdraw the required amount on the specified date.

  2. Bank Transfer (BACS, CHAPS, or Faster Payments): Payments can be made directly from your bank to HMRC. It's important to note that depending on your bank and the type of transfer, it may take up to 3 days for HMRC to receive the funds. Make sure to account for this delay if you’re paying close to the deadline.

  3. Credit or Debit Card: HMRC accepts payments via debit or credit card. However, it's important to note that there may be additional fees for credit card payments. Debit card payments, on the other hand, do not typically incur extra charges.

  4. At the Post Office: If you prefer to make payments in person, you can pay your tax bill at the Post Office. You’ll need to bring your payment slip from HMRC, and payment can be made in cash, by cheque, or with a debit card.

  5. By Cheque: You can send a cheque by post, but this method should be used cautiously as postal delays may lead to late payments. HMRC advises taxpayers to send cheques well before the deadline to avoid penalties. The cheque must be payable to “HM Revenue and Customs only” followed by your Unique Taxpayer Reference (UTR) number.


Example Scenario: Direct Debit Payment

Let’s say Rachel is a self-employed graphic designer who needs to pay her Self-Assessment tax bill. She logs into her HMRC account and sees that she owes £3,500 for the 2023-2024 tax year. Since she prefers to automate her payments and avoid missing deadlines, Rachel sets up a direct debit payment for the due date of 31 January 2025. This ensures that the money will be automatically withdrawn from her account without her needing to remember to make a manual payment.


Payments on Account: Understanding Advance Payments

If your tax bill exceeds £1,000, HMRC may ask you to make payments on account. These are advance payments towards your next year's tax bill, split into two installments: one due by 31 January and the second by 31 July.


Each payment on account is typically 50% of your previous year's tax bill. For example, if your tax bill for the 2023-2024 tax year is £2,000, you’ll need to pay £1,000 by 31 January 2025 and another £1,000 by 31 July 2025. When the 2024-2025 tax year concludes, HMRC will calculate your total liability and adjust your payments accordingly.


If your income for the next tax year is lower than expected, you can apply to reduce your payments on account. However, if you reduce your payments too much and end up owing more, you will need to pay the remaining balance by 31 January of the following year, plus any interest accrued on the shortfall.


Example Scenario: Payments on Account

Let’s consider Simon, a self-employed consultant. His tax bill for the 2023-2024 tax year is £3,000. As Simon's liability exceeds £1,000, HMRC asks him to make payments on account for the next tax year. Therefore, Simon must pay £1,500 by 31 January 2025 (50% of his current bill) and another £1,500 by 31 July 2025. By January 2026, HMRC will calculate Simon’s total tax liability for the 2024-2025 tax year and notify him if any further payment is required.


Refunds: What to Do If You’ve Overpaid

It’s not uncommon for taxpayers to overpay their Self-Assessment tax bill, particularly if provisional figures were used or if their circumstances changed during the tax year. If HMRC owes you a refund, you can request one through your online Self-Assessment account.


HMRC generally issues refunds within 10 working days of your request, and the refund will be paid directly into your nominated bank account. Alternatively, you can request a refund by cheque, although this may take longer to process.


Example Scenario: Claiming a Tax Refund

Tom, a self-employed photographer, estimated his income for the 2023-2024 tax year when he submitted his tax return in January 2025. However, by July 2025, he realizes that he overestimated his income and, therefore, overpaid his tax bill. Tom logs into his HMRC account and requests a refund of the overpaid amount. Within 10 days, the refund is credited to his bank account, and his tax situation is fully reconciled.


Correcting Errors on Your Tax Return

Mistakes happen, and it’s entirely possible to make an error when filling out your Self-Assessment tax return. Fortunately, HMRC allows taxpayers to amend their return after submission.


If you spot an error after submitting your tax return, you can correct it online if you filed the return electronically or by submitting an amended paper return if you filed by post. The window for making changes closes 12 months after the 31 January deadline. For the 2023-2024 tax year, this means you have until 31 January 2026 to correct any mistakes.


Common errors include:

  • Misreporting income: If you realize you failed to report income from a side job, rental property, or overseas investments, you can correct this by amending your return.

  • Claiming incorrect expenses: If you mistakenly claimed expenses that are not allowable or forgot to claim allowable expenses, you can amend this section of your return.

  • Incorrect tax relief claims: If you made an error in claiming tax relief on pension contributions, charitable donations, or investment losses, you can also correct this.


Example Scenario: Correcting a Tax Return Error

Emma, a freelance writer, submitted her Self-Assessment tax return on time for the 2023-2024 tax year. A few months later, she realizes she mistakenly forgot to include income from a short-term freelance contract she completed in the summer of 2023. As this income affects her total tax liability, Emma logs into her online HMRC account and amends her tax return to include the additional income. Since the error is corrected before the 31 January 2026 deadline, Emma avoids penalties or interest charges on the unpaid tax.


Appealing Penalties: What to Do If You Miss a Deadline

If you miss a Self-Assessment deadline for submitting your return or making a payment, HMRC will automatically issue a penalty. However, you may be able to appeal the penalty if you believe there were exceptional circumstances that caused the delay.

Common "reasonable excuses" include:


  • Serious illness or a hospital stay

  • The death of a close relative

  • Technical issues that prevented you from submitting your return online

  • Unforeseen postal delays (for paper returns)


If you have a valid reason for missing the deadline, you can appeal the penalty by contacting HMRC with supporting evidence. It’s important to do this as soon as possible to avoid accruing additional penalties.


Example Scenario: Appealing a Penalty

Sarah, a self-employed marketer, falls seriously ill just before the 31 January 2025 deadline for submitting her Self-Assessment return. She is unable to complete the return on time and subsequently receives a £100 late filing penalty. Sarah appeals the penalty by providing HMRC with a letter from her doctor explaining her illness. HMRC reviews the case and agrees to cancel the penalty based on the "reasonable excuse" provision.


Managing your Self-Assessment tax payments, refunds, and potential errors can seem overwhelming, but by understanding the various options and timelines available, you can ensure a smooth experience. HMRC offers flexibility in terms of payment methods, and the ability to correct errors or claim refunds ensures that you can address any issues that may arise during the process.


Understanding Income, Expenses, and Tax Reliefs for Self-Assessment

In the previous part, we discussed the processes for paying your tax bill, requesting refunds, and correcting errors. Now, we will dive deeper into one of the most important sections of your Self-Assessment tax return: declaring income, expenses, and claiming tax reliefs. By understanding which types of income need to be declared and which expenses can be deducted from your taxable income, you can ensure that you are compliant with HMRC’s rules while minimizing your tax liability.


Types of Income to Declare in Your Self-Assessment

The first step in completing your Self-Assessment tax return is declaring all of your taxable income for the 2023-2024 tax year. This includes income from various sources, not just your primary employment or business. It’s important to provide accurate figures, as failing to declare all income can result in penalties or interest on unpaid tax.


Here are some common types of income that need to be included:

  1. Self-employment income: If you’re self-employed or a sole trader, you need to report all income generated from your business activities. This includes payments received for goods and services, as well as any tips or gratuities.

  2. Employment income: If you have a job in addition to self-employment, you must declare your employment income. This includes salary, wages, bonuses, and other earnings from your employer that may not be fully taxed under the PAYE system.

  3. Property income: If you rent out property (whether a residential home, a commercial property, or even a room in your house through the Rent a Room scheme), you need to declare your rental income. You can also claim allowable expenses related to the property, which we’ll discuss in more detail later.

  4. Interest and investment income: This includes interest earned on savings accounts, dividends from shares, or profits from selling investments such as stocks and shares. Certain tax-free allowances, like the Personal Savings Allowance, may apply, but you must still report the total income.

  5. Foreign income: If you receive income from outside the UK, such as from property rentals, investments, or overseas employment, you need to declare it. The UK has agreements with many countries to avoid double taxation, but you must still report foreign income on your tax return.

  6. Capital gains: If you sold property, shares, or other assets for a profit during the tax year, you may need to pay Capital Gains Tax. It’s important to report any gains over the annual exempt amount, which for the 2023-2024 tax year is £6,000.


Example Scenario: Declaring Multiple Income Sources

David is a graphic designer who is both self-employed and employed part-time by a local marketing agency. He also rents out a flat, earns dividends from his stock investments, and has a savings account. When completing his Self-Assessment tax return, David must declare:


  • His income from freelance graphic design work (self-employment income).

  • His part-time salary from the marketing agency (employment income).

  • The rental income he receives from his flat (property income).

  • Dividends from his stock investments (investment income).

  • Interest earned on his savings account (interest income).


By accurately declaring all of his income, David ensures that he complies with HMRC’s rules and avoids penalties for underreporting.


Claiming Allowable Expenses

As a self-employed individual or business owner, one of the major benefits of the Self-Assessment system is the ability to deduct allowable expenses from your taxable income. These are costs that you incur during the day-to-day operation of your business, and they reduce your overall tax liability. However, it’s important to understand which expenses are allowable and how to calculate them.


Common Allowable Expenses

  1. Office costs: This includes expenses such as stationery, phone bills, and office supplies. If you work from home, you can also claim a portion of your home office costs, such as internet usage or rent, based on how much of your home is used for business purposes.

  2. Travel expenses: If you travel for business, you can claim for transport costs such as fuel, vehicle insurance, and train or bus tickets. However, travel from your home to your regular place of work is not claimable.

  3. Stock and materials: Any costs related to the purchase of stock, raw materials, or products that you sell in your business can be deducted.

  4. Marketing and advertising: This includes costs for promoting your business, such as website hosting fees, online advertising, or printed promotional materials.

  5. Employee wages: If you employ staff in your business, you can deduct their salaries, bonuses, and other employment-related costs from your taxable income.

  6. Professional fees and subscriptions: If you pay for legal or accountancy services, or if you’re a member of a professional organization, these costs can usually be claimed as an allowable expense.

  7. Utilities: Expenses related to water, gas, electricity, and other utilities can be claimed if they are used for business purposes. For home-based businesses, you can claim a portion of these expenses based on the space used for work.


Example Scenario: Claiming Expenses as a Self-Employed Individual

Sarah runs a small photography business from her home. She uses part of her home as an office and studio. She regularly travels to clients for photoshoots, and she recently purchased new camera equipment and paid for website hosting. Sarah can claim the following allowable expenses:


  • A portion of her home’s rent and utility bills, based on the percentage of space used for her photography business.

  • Travel costs for driving to clients, including fuel and car insurance.

  • The cost of purchasing new camera equipment and photography supplies.

  • Website hosting fees for her online portfolio.

  • Marketing expenses for promoting her business through social media ads.


By accurately claiming these expenses, Sarah reduces her taxable income, meaning she will owe less tax at the end of the year.


Tax Reliefs Available to Individuals

In addition to claiming expenses, there are several tax reliefs that individuals can apply for to reduce their overall tax liability. These tax reliefs are available to both employed and self-employed individuals, depending on their circumstances.


Common Types of Tax Reliefs

  1. Pension contributions: Contributions to a pension scheme are eligible for tax relief. Basic-rate taxpayers automatically receive relief on contributions, but higher-rate taxpayers can claim additional relief through Self-Assessment. For the 2023-2024 tax year, you can contribute up to £60,000 into your pension with full tax relief.

  2. Charitable donations: If you donate to charity through Gift Aid, you can claim additional tax relief if you’re a higher-rate taxpayer. For every £1 donated, the charity can claim an extra 25p, and higher-rate taxpayers can claim the difference between the basic and higher tax rates.

  3. Marriage Allowance: If you’re married or in a civil partnership, you may be able to transfer part of your Personal Allowance to your partner, reducing their tax bill. This is particularly useful if one partner earns less than the Personal Allowance threshold (£12,570 for the 2023-2024 tax year).

  4. Work from home allowance: If you are employed but working from home, you can claim a fixed amount of £6 per week for your home office costs without the need for receipts. If your actual costs are higher, you can claim more, but you’ll need to provide evidence.

  5. Trading allowance: The trading allowance allows you to earn up to £1,000 of income from casual or hobby-based work (e.g., selling crafts, freelance writing) without paying tax. If your income exceeds this threshold, you must report it, but the first £1,000 remains tax-free.


Example Scenario: Claiming Pension Contributions and Charitable Donations

James is a higher-rate taxpayer who makes regular contributions to his private pension scheme. In the 2023-2024 tax year, he contributes £10,000 to his pension. The pension provider claims basic-rate tax relief on this amount, but since James is a higher-rate taxpayer, he can claim an additional 20% relief (the difference between the basic and higher rates) through his Self-Assessment tax return. This means that for every £100 he contributes, James effectively pays only £60 after tax relief.


Additionally, James donates £500 to charity through Gift Aid. The charity claims £125 in basic-rate tax relief, and James can claim an additional £125 through his Self-Assessment.

By taking advantage of these tax reliefs, James reduces his overall tax liability, allowing him to save more for his retirement while also supporting charitable causes.


Understanding the different types of income, allowable expenses, and available tax reliefs is essential for completing your Self-Assessment tax return accurately and minimizing your tax bill. Whether you’re self-employed or have multiple income sources, knowing how to claim legitimate deductions and reliefs can save you significant amounts of money each year.


Submitting Your Self-Assessment Tax Return: Online vs. Paper Submission and Tips for Avoiding Common Mistakes

In this part of the article, we will cover the practical aspects of how to submit your Self-Assessment tax return, both online and on paper, and explore common mistakes that can lead to delays, rejections, or penalties. Whether you’re a first-time filer or a seasoned taxpayer, this section provides key insights and examples to help you avoid common pitfalls and ensure your tax return is submitted accurately and on time.


Online Submission: The Preferred Method

The vast majority of taxpayers choose to file their Self-Assessment tax returns online. Not only is this method faster and more convenient, but it also provides a longer deadline for submission — 31 January 2025 for the 2023-2024 tax year, compared to 31 October 2024 for paper returns. Additionally, online filing offers immediate confirmation of receipt, reducing the risk of lost paperwork and postal delays.


Steps to Submit Your Return Online

  1. Register for Self-Assessment and Get a Government Gateway ID: If you’ve never submitted a Self-Assessment tax return before, the first step is to register with HMRC. You can do this online by visiting the official HMRC website and creating a Government Gateway account. This process may take up to 10 working days, as HMRC will send an activation code by post.

    Once registered, you will receive your Unique Taxpayer Reference (UTR), which you’ll need to log into your account and file your return. You must ensure that you register for Self-Assessment well before the filing deadline to allow enough time for your registration to be processed.

  2. Log into Your Online Account: After you have registered and received your UTR, you can log into your Government Gateway account on HMRC’s Self-Assessment portal. From here, you can start filling in your tax return. The online system is designed to guide you through each section, prompting you for the necessary information.

  3. Enter Your Income and Expenses: The main part of the process involves entering your income from all sources, as well as any allowable expenses or tax reliefs that you’re claiming. The system provides helpful hints and checks to ensure that you’re entering the correct information.

  4. Review and Submit Your Return: Once you have completed all sections, the system will calculate your tax liability based on the figures you’ve entered. You can review your return before submitting it. Once you’re satisfied that all the information is accurate, you can submit your return online and receive an immediate confirmation from HMRC.


Example Scenario: Submitting a Tax Return Online

Emma is a self-employed web developer. She prefers to file her tax return online because it gives her more time to gather all her records and ensures she can submit her return close to the 31 January 2025 deadline. Emma logs into her Government Gateway account using her UTR and completes the return by entering her self-employment income, allowable business expenses (such as software subscriptions and travel costs), and any tax reliefs she is eligible for.


Once she’s reviewed the summary and confirmed that everything is correct, Emma submits her return online. Within seconds, she receives a confirmation email from HMRC, giving her peace of mind that her tax return has been filed successfully.


Paper Submission: What You Need to Know

Although online submission is preferred by HMRC, some taxpayers may choose or need to file a paper tax return. The paper filing deadline is 31 October 2024, and it’s important to ensure that HMRC receives your return by this date to avoid late penalties.


Steps to Submit Your Return by Paper

  1. Request the Relevant Forms: To submit your return by paper, you’ll need to request the appropriate form from HMRC. For most individuals, this will be form SA100, which is the main Self-Assessment tax return form. If you need supplementary pages (for example, if you have rental income or capital gains), you can download these forms from the HMRC website.

  2. Complete the Forms Accurately: When completing a paper tax return, you need to manually enter all of your income, expenses, and tax reliefs. Make sure that all figures are accurate, as mistakes can result in delays or rejection of your return. Double-check your calculations, as the system does not provide automatic prompts or checks like the online submission does.

  3. Post Your Return to HMRC: Once your tax return is complete, you’ll need to send it by post to HMRC. The address for postal submissions is:

    Self AssessmentHM Revenue and CustomsBX9 1ASUnited Kingdom

    It’s advisable to send your return via recorded delivery so that you have proof of submission in case of any issues. Ensure that you allow sufficient time for the postal service to deliver your return by the 31 October 2024 deadline.

  4. Wait for HMRC’s Confirmation: Unlike online submissions, you won’t receive an immediate confirmation when filing by paper. However, HMRC will send you a letter to acknowledge receipt of your return. If you don’t receive a confirmation letter within a few weeks of submission, it’s a good idea to contact HMRC to ensure that they received your return.


Example Scenario: Submitting a Paper Tax Return

John is a landlord who prefers to file his tax return by paper. He requests form SA100 from HMRC and downloads the supplementary form for property income. After filling out the forms and entering his rental income, allowable expenses (such as maintenance costs and property management fees), and personal details, John posts the return to HMRC in early October 2024 to ensure it arrives before the 31 October deadline. He sends the return via recorded delivery and receives a confirmation letter from HMRC a few weeks later.


Common Mistakes to Avoid When Submitting Your Return

Regardless of whether you submit your Self-Assessment return online or by paper, there are several common mistakes that can lead to delays, rejections, or penalties. Below, we outline some of the most frequent errors and how to avoid them:


  1. Missing the Deadline: One of the most common mistakes is missing the filing deadline. As mentioned earlier, the deadline for paper returns is 31 October 2024, and for online returns, it’s 31 January 2025. Missing the deadline by even one day will result in an automatic £100 penalty. To avoid this, make sure you file your return well in advance of the deadline.

  2. Incorrect or Missing Information: Failing to declare all of your income or entering incorrect figures can lead to underpayment of tax and potentially trigger an investigation by HMRC. Make sure that you have all the necessary paperwork, such as P60s, P45s, and bank statements, to ensure that your figures are accurate. Double-check the details before submitting your return.

    Example: If you forget to include your rental income on your tax return, HMRC may identify this discrepancy later, and you could face penalties and interest on the unpaid tax.

  3. Failing to Claim Allowable Expenses: Another common mistake is failing to claim all allowable expenses, which can increase your tax liability unnecessarily. Make sure you’re aware of the expenses you can deduct, such as travel costs, office supplies, and marketing expenses. Keep detailed records and receipts to support your claims.

  4. Incorrect Bank Details for Refunds: If you are expecting a tax refund, make sure that you enter your bank details correctly. Mistakes in your account number or sort code can delay your refund or cause it to be paid to the wrong account. Always double-check these details before submitting your return.

    Example: Rachel is expecting a £500 tax refund. However, she mistakenly enters the wrong sort code on her Self-Assessment form. As a result, her refund is delayed, and she has to contact HMRC to correct the issue, further prolonging the process.

  5. Not Declaring Foreign Income: If you have income from abroad, such as rental income from a property overseas or dividends from foreign investments, you must declare this on your UK tax return. The UK has double taxation agreements with many countries, which means you won’t be taxed twice, but failing to declare foreign income can lead to penalties.

    Example: Simon owns a holiday home in Spain that he rents out during the summer. Although he pays tax on the rental income in Spain, he must also declare it on his UK tax return. If Simon fails to do so, HMRC may impose penalties for underreporting income.

  6. Provisional Figures: If you do not know your exact income or expenses by the deadline, you can submit provisional figures and amend them later. However, you must clearly indicate that the figures are provisional, or HMRC may consider the information to be final, leading to problems down the line.

    Example: Jane is waiting for some final invoices from her clients, and the deadline is approaching. She uses provisional figures based on her past income but makes sure to mark them as provisional on her return. Once she receives the final invoices, she updates her return with the accurate figures.


Tips for a Smooth Submission

  • Start Early: Don’t wait until the last minute to begin your tax return. The earlier you start, the more time you have to gather all the necessary documents and address any issues.

  • Use HMRC’s Online Resources: HMRC provides helpful guidance on its website, including a Self-Assessment helpline and FAQs that can clarify any questions you may have.

  • Keep Good Records: Maintaining organized records throughout the year will make the Self-Assessment process much smoother. Keep receipts, invoices, bank.

There are several reasons why you might consider hiring a personal tax accountant to handle your Self-Assessment tax return, particularly if your financial situation is complicated or if you are not confident in completing the return yourself. Here are some of the key benefits:


  1. Expert Knowledge and Experience: Accountants are highly trained professionals who specialize in tax laws and financial regulations. They stay up to date with the latest changes in tax rules, including those for the 2023-2024 tax year, and can apply this knowledge to your specific situation. This expertise ensures that your tax return is accurate and that you are not missing out on any tax reliefs or deductions.

    For example, if you’re unsure whether certain expenses qualify as allowable deductions, an accountant can provide guidance and ensure that you’re maximizing your tax savings without violating HMRC rules.

  2. Time-Saving: Completing a Self-Assessment tax return can be a time-consuming process, especially if you are unfamiliar with the requirements. Hiring an accountant allows you to focus on running your business or managing your personal affairs while they handle the paperwork for you. They can collect all the necessary information, calculate your tax liability, and submit the return on your behalf.

    Example: Karen, a busy small business owner, decides to hire an accountant to manage her tax return. The accountant collects her financial records, calculates her allowable expenses, and files the return with HMRC. This saves Karen hours of work and ensures that her tax return is submitted on time.

  3. Reducing the Risk of Errors: Mistakes on your Self-Assessment tax return can lead to delays, penalties, and potential investigations by HMRC. Accountants have a thorough understanding of the common pitfalls that taxpayers face, and they can help you avoid errors such as underreporting income or failing to claim all available deductions.

    Example: John, a freelance writer, attempted to file his tax return on his own last year but mistakenly failed to report some income from a side project. This led to a penalty from HMRC. This year, John hires a tax accountant who reviews his financial records and ensures that all income and expenses are correctly reported, avoiding any penalties.

  4. Tax Planning and Advice: A personal tax accountant can provide ongoing tax planning advice, helping you to structure your finances in a tax-efficient manner. This is particularly valuable for individuals with complex financial situations, such as those with multiple sources of income, property investments, or international assets. An accountant can suggest strategies to reduce your tax liability, such as taking advantage of tax reliefs or maximizing pension contributions.

    Example: Emma, a high-income earner with investments in both the UK and abroad, consults her tax accountant for advice on how to minimize her tax liability. The accountant helps Emma make use of her personal allowance, claim relief on charitable donations, and ensures that she avoids paying unnecessary taxes on her foreign income.

  5. Support in Case of an HMRC Investigation: If HMRC decides to investigate your tax affairs, having an accountant on your side can be invaluable. They can communicate with HMRC on your behalf, provide all necessary documentation, and help resolve any issues that arise during the investigation.

    Example: Sarah, a self-employed consultant, receives a letter from HMRC indicating that her tax return is being investigated due to some discrepancies in her reported income. She hires an accountant who reviews her return, gathers the necessary records, and liaises with HMRC to explain the situation. The accountant’s involvement ensures that the investigation is resolved quickly and efficiently.


How Personal Tax Accountants Help in Specific Scenarios

Let’s break down how an accountant can assist in some common situations faced by UK taxpayers:


1. Self-Employed and Sole Traders

If you are self-employed, completing your Self-Assessment tax return can be more complicated than for someone who is solely employed under the PAYE system. You need to accurately report your business income and expenses, and there may be areas where it’s unclear whether an expense is allowable. A personal tax accountant can help you keep accurate records, claim the right expenses, and ensure that you are compliant with HMRC regulations.


Example: Tom runs a small plumbing business and isn’t sure how to account for his vehicle expenses. His accountant advises him to use the simplified expenses method for calculating business mileage, which saves him time and maximizes his deductions.


2. Landlords with Property Income

Landlords must report rental income and can claim various allowable expenses, such as maintenance costs, mortgage interest (subject to current rules), and letting agent fees. However, the rules regarding what is deductible can be complex, especially with recent changes in tax legislation. An accountant can ensure that all property-related expenses are claimed correctly and that you are making full use of any available reliefs, such as the Rent a Room scheme.


Example: James owns a rental property and is unsure about how to account for repairs and maintenance costs. His accountant clarifies that major renovations are not deductible in the same way as minor repairs and helps James claim only the allowable expenses, reducing his tax bill without risking penalties.


3. High-Income Earners and Complex Financial Situations

High-income earners often have more complicated tax returns, particularly if they have income from multiple sources or investments. There may also be additional tax considerations, such as the reduction of the personal allowance for those earning over £100,000 or additional tax liabilities like Capital Gains Tax. A personal tax accountant can help high earners optimize their tax planning, reduce their overall liability, and ensure compliance with all tax regulations.


Example: Claire is a partner in a law firm and earns over £150,000 a year. She is also entitled to bonuses and dividends from shares in the firm. Her accountant advises her on how to minimize her tax bill by maximizing her pension contributions and using gift aid to charitable donations. The accountant also ensures that she claims all allowable reliefs, keeping her tax liability as low as possible.


4. Individuals with Foreign Income

If you receive income from outside the UK, such as dividends from foreign investments or rent from an overseas property, you must report this income on your Self-Assessment tax return. Navigating the rules around foreign income can be tricky, especially when considering double taxation agreements. A personal tax accountant can ensure that you report your foreign income correctly and claim any relief available to avoid being taxed twice.


Example: David, a UK resident, owns a holiday home in France that he rents out during the summer. He pays taxes on the rental income in France, but he is also required to declare it on his UK tax return. David’s accountant ensures that he claims the correct foreign tax relief to avoid paying tax twice on the same income.


Choosing the Right Tax Accountant

When choosing a tax accountant, it’s important to find someone who understands your specific needs. For example, if you are self-employed, look for an accountant with experience in small business taxes. If you have a property portfolio, choose someone who specializes in landlord taxation.


It’s also important to consider the following:

  • Qualifications: Ensure that the accountant is qualified and regulated by a professional body such as the Association of Chartered Certified Accountants (ACCA) or the Institute of Chartered Accountants in England and Wales (ICAEW).

  • Experience: Choose an accountant who has experience in handling Self-Assessment tax returns, particularly for individuals with similar circumstances to yours.

  • Communication: Good communication is key. Your accountant should be approachable and able to explain tax matters in a way that you understand.

  • Fees: Accountants typically charge a fee for their services, so it’s important to understand their fee structure. Some charge a flat rate for completing a tax return, while others may bill by the hour. Make sure the fees are transparent and fit within your budget.


Filing a Self-Assessment tax return can be a daunting task, especially for those with complex financial situations or limited knowledge of tax laws. A personal tax accountant can provide invaluable support, ensuring that your return is accurate, compliant, and optimized to reduce your tax liability. Whether you’re self-employed, a landlord, or an individual with foreign income, a tax accountant can help you navigate the complexities of the UK tax system and avoid costly mistakes.
