Understanding Non-Coded Income: Definition, Types, and Examples
What Is Non-Coded Income?
Non-coded income is any taxable income that HMRC does not include in a taxpayer's PAYE tax code. Instead of being taxed through payroll deductions, tax on this income is collected through other methods, such as Self Assessment or adjustments to a future tax bill.
This type of income typically arises when HMRC cannot adjust a tax code to account for certain earnings or when the income is irregular, unpredictable, or separate from a primary employment or pension source.
Why Does Some Income Remain Non-Coded?
HMRC uses tax codes to estimate how much tax an individual owes on their regular salary or pension. However, some types of income cannot be effectively coded because:
The amount is variable or difficult to predict in advance.
The taxpayer is already at the highest tax bracket, meaning additional income needs separate handling.
The income comes from sources that are not linked to an employer or pension provider.
The income is one-off or irregular, making it impractical to spread deductions across the year.
In such cases, HMRC leaves the income out of the tax code, and the taxpayer must ensure the correct tax is paid.
Common Types of Non-Coded Income
Non-coded income can come from various sources. Below are some of the most common types that UK taxpayers need to be aware of.
1. Self-Employment and Freelance Income
Self-employed individuals and freelancers often have income that is not taxed at source. If they also have employment income, HMRC may not adjust their PAYE tax code to include their self-employment earnings, meaning these earnings remain non-coded.
Example:
Jane works full-time as an accountant but also freelances as a financial consultant on weekends. Her employer taxes her salary through PAYE, but the income from her freelance work remains non-coded. She must report this extra income through a Self Assessment tax return and pay the tax separately.
2. Rental Income from Property
Earnings from letting out property are another common form of non-coded income. Landlords receive rent payments without tax deducted, meaning they must report and pay tax on this income separately.
Example:
David owns a buy-to-let property and earns £12,000 per year in rental income. Since this money isn’t taxed through PAYE, HMRC classifies it as non-coded income, and David must declare it via Self Assessment.
3. Investment and Dividend Income
Interest from savings accounts, dividends from shares, and other investment income are often not included in tax codes, particularly when they exceed tax-free allowances.
Example:
Sophia earns £3,000 in dividends from company shares. Since the dividend allowance for the 2024/25 tax year is £500, she must pay tax on the remaining £2,500 as non-coded income.
4. Capital Gains from Selling Assets
If a taxpayer makes a profit from selling assets such as property, stocks, or valuable items, this is subject to Capital Gains Tax (CGT). Since CGT does not operate through PAYE, it is always non-coded.
Example:
Mark sells a second home and makes a capital gain of £50,000. This exceeds the £3,000 CGT allowance (valid for the 2024/25 tax year), so Mark must report and pay tax on £47,000 in non-coded income.
5. Foreign Income
If a UK resident receives income from overseas employment, rental property abroad, or foreign investments, HMRC often does not include it in the tax code.
Example:
Emma, a UK resident, earns £8,000 in rental income from a property in Spain. Since this money is not subject to UK PAYE, it is considered non-coded income, and she must report it via Self Assessment.
6. Certain Pension Payments and Lump Sums
While most pension income is taxed through PAYE, certain lump-sum withdrawals and small pension payments may not be coded.
Example:
Paul withdraws £20,000 as a lump sum from his private pension. Since only 25% of this is tax-free, the remaining £15,000 is taxable but remains non-coded if HMRC does not adjust his tax code.
How Much Tax Is Paid on Non-Coded Income?
The tax rate on non-coded income depends on the individual’s total taxable earnings for the year. The 2024/25 income tax bands in England, Wales, and Northern Ireland are:
Tax Band | Taxable Income (£) | Tax Rate |
Personal Allowance | Up to £12,570 | 0% |
Basic Rate | £12,571 – £50,270 | 20% |
Higher Rate | £50,271 – £125,140 | 40% |
Additional Rate | Over £125,140 | 45% |
(Scotland has different income tax bands.)
If non-coded income pushes a taxpayer into a higher tax band, they may owe more tax than expected.
Example:
Liam earns £48,000 from his salary (PAYE taxed) and £5,000 in freelance income (non-coded). This extra income pushes him into the higher tax band for part of his earnings, meaning some will be taxed at 40% instead of 20%.
How Does HMRC Collect Tax on Non-Coded Income?
Since tax isn’t deducted at source, HMRC collects tax on non-coded income in one of three ways:
Self Assessment Tax Return – Taxpayers earning over £1,000 in untaxed income must file a Self Assessment and pay the tax themselves.
Simple Assessment – HMRC may send a bill directly, removing the need for a tax return.
Adjustments in Future Tax Codes – If the amount is small, HMRC may spread the tax owed across future PAYE tax codes.
How HMRC Handles Non-Coded Income: Tax Collection and Reporting
How HMRC Identifies Non-Coded Income
Non-coded income is essentially any untaxed income that HMRC does not include in a taxpayer’s PAYE tax code. But how does HMRC know that a taxpayer has non-coded income? The process varies depending on the type of income and whether HMRC has already been notified.
Here are the main ways HMRC identifies non-coded income:
Self-Reporting by the Taxpayer – Individuals are legally required to inform HMRC if they receive taxable income that is not already taxed through PAYE.
Bank and Financial Institution Reports – Banks, investment firms, and pension providers may report taxable interest, dividends, and pension withdrawals to HMRC.
Employer and Payroll Submissions – Employers provide payroll data to HMRC, which helps them cross-check undeclared income.
Property and Investment Data Sharing – HMRC has agreements with financial institutions and overseas tax authorities to track rental and investment income.
Digital Tax Records and Data Matching – HMRC uses sophisticated data analytics to flag discrepancies in taxpayers' declared income.
If HMRC detects undeclared non-coded income, it may contact the taxpayer, request additional details, or even issue penalties for non-disclosure.
When and How to Report Non-Coded Income
1. Through Self Assessment Tax Return
The most common way to report non-coded income is by filing a Self Assessment tax return. This applies if a taxpayer earns more than £1,000 in untaxed income or falls under other reporting requirements set by HMRC.
Who Needs to File a Self Assessment for Non-Coded Income?
Self-employed individuals and freelancers earning over £1,000 per year.
Landlords receiving rental income.
Investors with taxable dividends or interest exceeding allowances.
Individuals with capital gains exceeding the annual exemption.
Those receiving foreign income that needs to be taxed in the UK.
Deadlines for Self Assessment Reporting
Deadline | Applies to |
5 October | Register for Self Assessment if you haven’t filed before |
31 October | Paper tax return submission deadline |
31 January | Online tax return submission & tax payment deadline |
Failing to file a return on time can result in penalties starting from £100, increasing if further delays occur.
2. Through Simple Assessment (If Eligible)
For some individuals with non-coded income, HMRC may issue a Simple Assessment instead of requiring a Self Assessment return. This is a system where HMRC calculates the tax owed and sends the taxpayer a bill.
Who Gets a Simple Assessment?
Pensioners who owe tax on state pensions exceeding their Personal Allowance.
Taxpayers with one-off non-coded income that HMRC can calculate without a full Self Assessment.
Simple Assessments must be paid by 31 January following the end of the tax year.
3. Through PAYE Tax Code Adjustments (For Small Amounts)
For smaller amounts of non-coded income, HMRC may collect tax by adjusting the individual’s PAYE tax code for the next tax year.
How Does This Work?
HMRC estimates the taxpayer’s additional income.
They adjust the tax code to collect more tax each month.
The taxpayer does not need to pay a lump sum separately.
This method is often used for small rental earnings, occasional freelance work, or modest investment income.
How HMRC Collects Tax on Non-Coded Income
Once non-coded income has been reported, HMRC collects the tax using one of the following methods:
1. Self-Assessment Tax Payments
If a taxpayer is required to file a Self Assessment, they must calculate and pay their tax bill by 31 January following the end of the tax year.
For example:
The 2024/25 tax year runs from 6 April 2024 – 5 April 2025.
Tax on non-coded income for this period must be paid by 31 January 2026.
2. Payment on Account (For Self-Employed and High Earners)
Taxpayers who owe more than £1,000 in tax on non-coded income may have to make advance payments, known as Payments on Account. These are split into two instalments:
Payment Date | Amount Due |
31 January | First Payment on Account (50% of estimated tax bill) |
31 July | Second Payment on Account (50% of estimated tax bill) |
These payments help spread the tax burden across the year. If actual income is lower than expected, the taxpayer can request a reduction in Payments on Account.
3. PAYE Adjustments for Small Amounts
If a taxpayer’s non-coded income is relatively small, HMRC may adjust their tax code so that the owed tax is collected gradually from future salary or pension payments.
Example:
Sarah earns £2,000 in untaxed side income.
HMRC adjusts her tax code to collect the extra tax through PAYE in the following year.
This avoids the need for a lump-sum tax payment.
However, if the income fluctuates, relying on this method can lead to underpayments or overpayments, requiring adjustments later.
What Happens If You Don't Report Non-Coded Income?
Failing to report non-coded income can have serious consequences. HMRC has strict penalties for taxpayers who do not declare taxable earnings.
1. Late Filing Penalties
If a Self Assessment tax return is required but not submitted on time, the penalties are:
Delay | Penalty |
1 day late | £100 fine |
3 months late | £10 per day (up to £900) |
6 months late | £300 or 5% of unpaid tax (whichever is higher) |
12 months late | Additional £300 or 5% of unpaid tax |
2. Late Payment Penalties
If tax on non-coded income is not paid on time, additional penalties apply:
Delay | Penalty |
30 days late | 5% of unpaid tax |
6 months late | Additional 5% of unpaid tax |
12 months late | Further 5% of unpaid tax |
3. Interest on Late Payments
HMRC also charges daily interest (set at Bank of England base rate + 2.5%) on unpaid tax until it is fully settled.
4. HMRC Investigations and Penalties for Non-Disclosure
If HMRC discovers that a taxpayer deliberately failed to report non-coded income, they may issue additional penalties, which can be as high as 100% of the unpaid tax in cases of fraud.
How to Avoid Issues with Non-Coded Income
To avoid penalties and ensure compliance, taxpayers should:
Keep accurate records of all untaxed income.
Register for Self Assessment if required.
Use HMRC’s online tax calculator to estimate tax liabilities.
Make Payments on Account if applicable to avoid large tax bills.
Contact HMRC if unsure about reporting obligations.
Implications of Non-Coded Income for UK Taxpayers
Who Is Affected by Non-Coded Income?
Non-coded income impacts different types of taxpayers in the UK, including:
Employees with additional income sources (e.g., freelance work, rental income, or dividends).
Self-employed individuals who have both PAYE earnings and business profits.
Landlords earning rental income from properties.
Investors receiving dividends or capital gains.
Pensioners with additional non-PAYE taxable income.
For each group, non-coded income affects tax liability, payment methods, and potential obligations to HMRC. Let’s break down these implications for different taxpayer categories.
Employees with Non-Coded Income
Many employees assume that tax is automatically handled through PAYE. However, if they earn extra income outside of their salary, it may not be included in their tax code. This can lead to:
Higher tax bills than expected – If untaxed earnings push them into a higher tax bracket, they may owe additional tax at 40% or 45%.
Self Assessment requirement – Employees earning over £1,000 in untaxed income must register for Self Assessment.
Potential HMRC adjustments – If non-coded income is small, HMRC may adjust the tax code to collect tax via PAYE in the following year.
Example:
Tom earns £45,000 from his job but also makes £6,000 annually from freelance work.
Since his extra income is non-coded, he must file a Self Assessment and pay tax at 40% on the portion exceeding £50,270.
Self-Employed Individuals and Business Owners
For self-employed taxpayers who also have PAYE income, non-coded income creates additional tax responsibilities:
Separate tax calculation – While PAYE deductions cover their salary, self-employment income must be declared and taxed separately.
Payments on Account – If tax owed exceeds £1,000, HMRC requires advance payments (due 31 January and 31 July).
National Insurance Contributions (NICs) – Depending on profits, they may owe Class 2 and Class 4 NICs in addition to Income Tax.
Example:
Sarah earns £30,000 from a part-time job (PAYE) and £20,000 from her small business.
PAYE covers her salary, but she must report and pay tax on the £20,000 non-coded income.
She also owes NICs on her business earnings.
Landlords and Property Investors
Landlords often face non-coded income issues, as rental earnings are usually not taxed at source.
Rental income is self-reported – Landlords must declare rental profits via Self Assessment.
Tax is based on net income – Deductible expenses (e.g., mortgage interest, repairs) can reduce taxable income.
Higher-rate tax issues – Additional rental income can push taxpayers into a higher tax bracket.
Mortgage Interest Restrictions – Since 2020, landlords cannot deduct mortgage interest from rental income but receive a 20% tax credit instead.
Example:
James earns £40,000 from his job and £15,000 from rental income.
His total income is now £55,000, pushing part of his rental earnings into the 40% tax bracket.
Investors and Dividend Earners
Non-coded income is a key concern for those earning interest, dividends, or capital gains.
Dividends exceeding £500 (2024/25 limit) are taxable at 8.75%, 33.75%, or 39.35%.
Savings income beyond the Personal Savings Allowance (£1,000 for basic rate taxpayers, £500 for higher rate) is taxable.
Capital gains over £3,000 (2024/25 limit) are subject to Capital Gains Tax (CGT) at 10% or 20% (property gains taxed at 18% or 24%).
Example:
Emma receives £3,500 in dividends and £7,000 from selling shares.
She owes tax on £3,000 in dividends and £4,000 in capital gains.
Pensioners with Non-Coded Income
Pensioners receiving state pensions, annuities, or investment income may also have non-coded income, leading to:
State pensions often being untaxed at source – HMRC may adjust tax codes for other pensions to collect tax.
Self Assessment for high-income pensioners – Those earning over £1,000 in untaxed income must file a tax return.
Tax liabilities from lump-sum pension withdrawals – Only 25% of most pension withdrawals are tax-free; the rest is taxable as income.
Example:
Peter receives £16,000 from his state pension and £10,000 from an annuity.
Since state pensions aren’t taxed at source, HMRC adjusts his tax code to deduct tax from his annuity.
Impact of Non-Coded Income on Tax Rates
Non-coded income affects tax liability based on total taxable earnings. Below is a summary of the 2024/25 UK tax bands:
Tax Band | Taxable Income (£) | Tax Rate |
Personal Allowance | Up to £12,570 | 0% |
Basic Rate | £12,571 – £50,270 | 20% |
Higher Rate | £50,271 – £125,140 | 40% |
Additional Rate | Over £125,140 | 45% |
Example:
Laura earns £48,000 from her job and £10,000 in investment income.
Since this pushes her total income to £58,000, part of her investment income is taxed at 40% instead of 20%.
Other Financial Considerations
1. Student Loan Repayments
If total earnings (including non-coded income) exceed £27,295 (Plan 2) or £21,000 (Plan 1), extra repayments are required.
2. High-Income Child Benefit Charge (HICBC)
If total income exceeds £50,000, a Child Benefit tax charge applies.
3. Loss of Personal Allowance for High Earners
Those earning over £100,000 lose £1 of Personal Allowance for every £2 earned, making non-coded income even costlier.
Practical Steps for Managing and Declaring Non-Coded Income
Managing non-coded income effectively is crucial to avoid unexpected tax bills, penalties, or overpayments. Many taxpayers unknowingly make errors when handling non-coded income, which can lead to financial stress and unnecessary costs. In this section, we will cover step-by-step methods to track, report, and optimize tax efficiency on non-coded income.
Step 1: Identify and Track Non-Coded Income
The first step in managing non-coded income is to ensure you accurately identify all sources of such income and maintain proper records. Some income sources might not immediately appear on your tax radar, leading to unintentional tax underpayments.
How to Identify Non-Coded Income
Make a checklist of possible non-coded income sources, including:
✔ Freelance or self-employed earnings.
✔ Rental income from property.
✔ Dividends or savings interest beyond allowances.
✔ Capital gains from selling assets.
✔ Pension lump sums or excess withdrawals
.✔ Foreign income from overseas work, rental, or investments.
Example:
Sophie, a full-time employee, starts an online side business selling handmade jewelry. She assumes that because she only makes £3,500 a year, she does not need to report it. However, because it exceeds the £1,000 trading allowance, HMRC expects her to declare it.
Record-Keeping Best Practices
To prevent miscalculations or missing income declarations:
Keep detailed records of all untaxed income sources (bank statements, invoices, receipts).
Use accounting software like QuickBooks, FreeAgent, or HMRC’s digital tax tools.
Separate personal and business finances if running a side business.
Retain records for at least six years as required by HMRC.
Step 2: Determine If You Need to Register for Self Assessment
HMRC requires Self Assessment for taxpayers earning over £1,000 in untaxed income per tax year. If you haven’t registered before, you must sign up by 5 October following the tax year in which the income was earned.
How to Register for Self Assessment
Go to HMRC’s registration page (gov.uk/register-for-self-assessment).
Choose the correct category:
Self-employed (if you run a business).
Not self-employed (for rental, investments, or other personal income).
Receive your Unique Taxpayer Reference (UTR) from HMRC.
Set up a Government Gateway account to manage tax submissions.
Example:
John earns £900 in dividends and £1,200 from renting out a spare room (above the £1,000 property allowance). Because his non-coded income exceeds £1,000, he must register for Self Assessment.
Step 3: Accurately Report and File Tax Returns
Once registered for Self Assessment, you must submit a Self Assessment tax return (SA100 form) online or via paper. The deadline depends on the method used:
Submission Type | Deadline |
Paper tax return | 31 October after the tax year ends |
Online tax return | 31 January after the tax year ends |
Payment of owed tax | 31 January after the tax year ends |
Breakdown of the Self Assessment Filing Process
Step 1: Log into HMRC’s online tax return portal.
Step 2: Fill out relevant sections (e.g., self-employment, rental, dividend income).
Step 3: Calculate tax owed using HMRC’s tax return estimator.
Step 4: Submit the return before the deadline and make any required tax payments.
Example:
Laura earns £49,000 from employment and £4,500 from online tutoring. The extra earnings push her total taxable income to £53,500, meaning part of it is taxed at 40% (higher rate). She files a Self Assessment return and pays tax on the £4,500 in non-coded income.
Step 4: Plan for Tax Payments and Avoid Penalties
Taxpayers handling non-coded income must prepare for payments in advance. Failure to do so can result in penalties, interest charges, or unexpected tax bills.
How to Pay Tax on Non-Coded Income
Via Self Assessment – Pay online using debit/credit cards, bank transfers, or direct debit.
By PAYE Tax Code Adjustment – If HMRC includes small amounts of non-coded income in your tax code, tax is deducted gradually from your PAYE salary.
Through Simple Assessment – If HMRC calculates the tax for you, they send a bill to pay directly.
Avoiding Late Payment Penalties
Missed payment penalties start at 5% of the unpaid tax after 30 days.
HMRC applies daily interest on late tax payments.
Payment on Account may be required for those owing over £1,000 in non-coded tax.
Example:
David owes £3,500 in tax on his rental earnings. Because he does not pay by 31 January, HMRC applies a 5% late penalty (£175) plus daily interest until paid.
Step 5: Reduce Tax Liability Through Allowances and Deductions
To legally reduce tax on non-coded income, taxpayers should use available tax reliefs and allowances.
Key Tax-Free Allowances (2024/25 Tax Year)
Allowance Type | Tax-Free Amount (£) |
Personal Allowance | 12,570 |
Trading Allowance | 1,000 |
Property Allowance | 1,000 |
Dividend Allowance | 500 |
Personal Savings Allowance (basic rate) | 1,000 |
Capital Gains Tax Allowance | 3,000 |
Example:
Emily earns £2,500 from freelance writing but can claim the £1,000 trading allowance. She only pays tax on £1,500 instead of the full amount.
Additional Tax Deductions
✔ Self-employed expenses (office costs, travel, professional fees).
✔ Landlord expenses (repairs, insurance, letting fees).
✔ Pension contributions (tax relief up to annual allowance).
Example:
James earns £20,000 in rental income.
He claims £5,000 in deductible expenses.
He only pays tax on £15,000 instead of the full £20,000.
Step 6: Seek Professional Advice If Needed
For complex non-coded income cases, hiring a tax accountant or using HMRC’s tax helpline can help avoid errors.
When to Seek Help
If annual non-coded income exceeds £50,000.
If earnings push you into higher tax brackets.
If dealing with foreign income or capital gains tax.
If you’re unsure how to claim deductions and allowances.
Common Mistakes, Future HMRC Changes, and Practical Insights on Non-Coded Income
Common Mistakes to Avoid When Handling Non-Coded Income
Many UK taxpayers make errors when managing non-coded income, leading to unexpected tax bills, penalties, or HMRC investigations. Here are some of the most frequent mistakes and how to avoid them.
1. Failing to Declare Non-Coded Income
One of the biggest mistakes is assuming that HMRC automatically knows about all sources of income. While some financial institutions report interest and dividends, other earnings—such as rental income, freelancing, or foreign income—often go unreported unless the taxpayer takes action.
How to Avoid It:
✔ Keep a detailed record of all untaxed income.
✔ Register for Self Assessment if required.
✔ Regularly review your HMRC personal tax account to check what’s being reported.
Example:
Adam earns £3,000 per year from renting out a room on Airbnb. Since this exceeds the £1,000 property allowance, it is taxable. He assumes HMRC will adjust his tax code automatically, but because he doesn't report it, he receives a penalty for undeclared income.
2. Underestimating Tax Due on Non-Coded Income
Many people miscalculate their tax liability, especially when additional income pushes them into a higher tax bracket.
How to Avoid It:
✔ Use HMRC’s tax calculator to estimate tax owed.
✔ Understand how different types of income are taxed.
✔ Set aside a portion of earnings to cover future tax bills.
Example:
Emma earns £47,000 from her salary and £6,000 from side freelance work. She assumes her freelance income is taxed at 20%, but since her total income exceeds £50,270, part of her freelance earnings is taxed at 40%. She faces a higher tax bill than expected.
3. Missing Tax Deadlines
Late filing and payment of tax bills can lead to significant penalties and interest charges.
How to Avoid It:
✔ Mark key tax deadlines in a calendar.
✔ Set up reminders for Self Assessment and tax payments.
✔ File tax returns early to avoid last-minute issues.
Example:
Sarah forgets to submit her Self Assessment by 31 January and receives an automatic £100 fine. After three months, the fine increases to £10 per day, making her total penalty over £900.
4. Not Keeping Proper Records
HMRC requires taxpayers to maintain records for at least six years, but many individuals fail to track their earnings, expenses, and deductions properly.
How to Avoid It:
✔ Use accounting software or apps like QuickBooks or FreeAgent.
✔ Keep digital copies of invoices, receipts, and bank statements.
✔ Separate personal and business finances if self-employed.
Example:
Mark, a landlord, does not keep receipts for repairs on his rental property. When HMRC reviews his tax return, he is unable to claim £2,000 in expenses, resulting in a higher tax bill.
5. Ignoring HMRC Notices and Adjustments
HMRC sometimes adjusts tax codes or issues Simple Assessments for non-coded income. Ignoring these notices can result in unpaid tax accumulating over time.
How to Avoid It:
✔ Regularly check your HMRC personal tax account.
✔ Read and respond to HMRC letters and emails promptly.
✔ Seek clarification if you don’t understand a tax code adjustment.
Example:
Lucy receives a letter stating that HMRC has adjusted her tax code due to additional income, but she ignores it. At the end of the year, she discovers she owes £2,500 in unpaid tax.
Future HMRC Changes and Digital Taxation Trends
The UK tax system is evolving, with HMRC implementing digital systems and increasing tax compliance measures. Here are some key developments that will affect how non-coded income is reported and taxed.
1. Making Tax Digital (MTD) for Income Tax
MTD is set to change how self-employed individuals, landlords, and certain taxpayers report their earnings.
Those earning over £50,000 from self-employment or property will need to keep digital records and submit quarterly tax updates to HMRC.
The threshold will later be lowered to £30,000, bringing more taxpayers into the system.
Manual record-keeping and annual tax returns will eventually be phased out.
What This Means for You:
✔ If you’re a landlord or self-employed, prepare to switch to HMRC-approved accounting software.
✔ Keep records updated throughout the year rather than waiting for the tax deadline.
2. Stricter Compliance on Rental and Investment Income
HMRC is increasing its use of data-matching technology to identify taxpayers who fail to report rental or investment income.
Banks, estate agents, and online rental platforms (such as Airbnb) now share income data with HMRC.
Offshore investment income is being closely monitored under global tax transparency agreements.
Landlords receiving income from short-term lettings (e.g., Airbnb, Booking.com) may receive automatic tax assessments in the future.
What This Means for You:
✔ Ensure all property and investment income is reported correctly.
✔ Keep a record of expenses and allowable deductions to reduce taxable profits.
3. Changes to Personal Allowances and Tax Bands
The government has frozen income tax thresholds, meaning more people will pay higher rates of tax as earnings increase.
The personal allowance remains unchanged, but inflation means more taxpayers will drift into the higher tax band.
Dividend and capital gains tax allowances have been reduced, meaning investors will pay more tax.
Future adjustments to National Insurance may impact how non-coded income is taxed.
What This Means for You:
✔ Regularly check how tax band changes affect your earnings.
✔ Consider tax-efficient investments such as ISAs or pension contributions to reduce taxable income.
Final Practical Insights on Managing Non-Coded Income
To successfully manage non-coded income and remain tax-compliant, follow these best practices:
1. Budget for Tax Payments
Set aside 20-40% of non-coded income to cover tax bills.
Use a separate savings account to prevent spending tax money accidentally.
2. Use Tax-Efficient Strategies
Maximize the use of tax-free allowances (property, trading, dividend).
Invest through ISAs and pensions to reduce taxable income.
3. Seek Professional Advice If Necessary
If your non-coded income is complex, consult an accountant or tax adviser.
Use HMRC’s online tools and tax helplines for guidance.
4. Stay Updated on Tax Law Changes
Follow GOV.UK updates to keep track of new tax regulations.
Be aware of upcoming HMRC digital reporting requirements.
Summary of Key Points on Non-Coded Income
Non-coded income refers to taxable income that is not included in a taxpayer’s PAYE tax code and must be reported separately.
Common types of non-coded income include self-employment earnings, rental income, dividends, capital gains, foreign income, and certain pension payments.
Tax on non-coded income is collected through Self Assessment, Simple Assessment, or PAYE tax code adjustments, depending on the amount and source.
Individuals earning over £1,000 in untaxed income must register for Self Assessment and file a tax return by 31 January.
Failing to report non-coded income can result in penalties, interest charges, and potential HMRC investigations.
Taxpayers can reduce their tax liability using allowances and deductions, such as the trading allowance, property allowance, and pension contributions.
HMRC is increasing compliance checks on rental, investment, and foreign income, using data-sharing agreements and digital tax records.
Making Tax Digital (MTD) for Income Tax will soon require landlords and self-employed individuals earning over £50,000 to submit quarterly tax updates online.
Late filing of Self Assessment tax returns leads to a minimum penalty of £100, increasing with delays, while late payments incur additional fines and daily interest.
To stay compliant and avoid tax issues, taxpayers should track all non-coded income, budget for tax payments, use tax-efficient strategies, and seek professional advice if needed.
FAQs
1. Q: Can you request HMRC to include non-coded income in your tax code instead of paying it separately?
A: Yes, in some cases, HMRC can adjust your tax code to collect tax on non-coded income through PAYE, but this depends on the amount and nature of the income.
2. Q: Does receiving non-coded income affect your eligibility for government benefits or tax credits?
A: Yes, non-coded income can impact means-tested benefits and tax credits, as it increases your total taxable income, potentially reducing the support you receive.
3. Q: How does non-coded income affect your National Insurance contributions (NICs)?
A: Unlike PAYE earnings, some non-coded income, such as rental profits and investment returns, may not be subject to NICs, but self-employment income is liable for Class 2 and Class 4 NICs.
4. Q: What should you do if you receive an HMRC Simple Assessment for non-coded income but believe it is incorrect?
A: You must contact HMRC within 60 days of receiving the Simple Assessment to dispute or correct any errors.
5. Q: Can HMRC estimate your non-coded income and issue a tax bill even if you haven’t reported it?
A: Yes, HMRC uses data from banks, employers, and digital tax records to estimate untaxed income and may send a tax bill based on those figures.
6. Q: Does non-coded income include money earned from selling personal belongings, such as old furniture or clothes?
A: No, unless you are regularly buying and selling items for profit, in which case HMRC may consider it trading income and subject to tax.
