Understanding Tax Refunds and How They Work in the UK
If you've ever wondered whether HMRC owes you money, you're not alone. Every year, thousands of UK taxpayers overpay on their taxes—whether through PAYE (Pay As You Earn), self-assessment, pension overpayments, or emergency tax deductions—and many don’t even realise they’re due a refund.
This comprehensive guide will help you check if you’re eligible for a tax refund, how to claim it, and what steps to take if HMRC owes you money. Let’s get started!
What is a Tax Refund?
A tax refund (also called a tax rebate) is money returned to you when you've overpaid tax to HMRC. This could happen for several reasons, such as:
Incorrect PAYE tax codes used by your employer
Working multiple jobs and overpaying tax due to different tax codes
Self-employed individuals overestimating their tax payments
Leaving the UK partway through the tax year
Claiming work-related expenses (like uniforms, tools, or mileage) but not getting tax relief
Overpaying Capital Gains Tax (CGT) or dividend tax
Paying emergency tax when starting a new job
Pension withdrawals over a certain threshold triggering overpayments
Important: HMRC does not automatically refund every overpayment. In many cases, you need to check and claim the money yourself!
Who Can Get a Tax Refund in the UK?
Different types of UK taxpayers may be eligible for a tax refund, including:
Taxpayer Type | Common Reasons for a Refund |
PAYE employees | Wrong tax code, work expenses, emergency tax, job changes |
Self-employed (Self Assessment) | Overpayment on account payments, allowable business expenses |
Company directors | Dividend tax refunds, corporation tax overpayments |
Students & part-time workers | Earning under the tax-free threshold but taxed incorrectly |
Pensioners | Overpaid tax on pension withdrawals |
Freelancers & gig workers | Expenses deductions not applied |
People leaving the UK | Tax refunds for part-year residency |
Construction workers (CIS Scheme) | Overpaid deductions under CIS rules |
How Much Tax Refund Can You Get?
The amount of tax refund you can claim depends on how much tax you overpaid. Here’s a look at the most common scenarios:
1. PAYE Overpayment Refunds
If you’re a salaried employee, you might have been put on an emergency tax code or an incorrect tax bracket.
The standard Personal Allowance for 2024/25 is £12,570 (you don’t pay tax on earnings below this).
If you were taxed before your employer received the correct tax code, you may have overpaid income tax.
If you worked multiple jobs, HMRC might have applied the wrong tax-free allowance across your jobs.
Example: Emma started a new job in May 2024 and was put on the emergency tax code 1257L W1/M1. She earned £30,000 but was taxed as if she had no tax-free allowance. She overpaid £1,200 in tax. Once HMRC corrected her tax code, she became eligible for a refund.
2. Self-Employed & Self-Assessment Refunds
Self-employed people often overpay tax due to:
Making ‘Payments on Account’ based on estimated earnings that turned out lower
Claiming business expenses deductions late
Overpaying National Insurance contributions (NICs)
Example: David is a freelancer who made £20,000 in 2024/25. His Payment on Account for the following year was based on £30,000 earnings, so he overpaid £1,800 in advance tax. After filing his return in January 2026, HMRC issued him a refund.
3. CIS Tax Refunds (For Construction Workers)
If you work in the construction industry under the CIS (Construction Industry Scheme), your employer may have deducted 20% tax at source. If your actual tax bill is lower, you can reclaim the difference.
Example: Liam earned £30,000 as a subcontractor and had £6,000 deducted under CIS. However, his total tax liability (after expenses) was only £3,500, meaning he could claim back £2,500 from HMRC.
4. Pension & Retirement Tax Refunds
Pension withdrawals above £12,570 may get taxed incorrectly—especially lump sum withdrawals. If you’ve cashed in part of your pension and overpaid tax, you can claim it back.
Example: Mary took a £20,000 pension withdrawal but was taxed at 40% (£8,000) instead of her normal 20% (£4,000) rate. She later applied for a £4,000 refund from HMRC.
5. Overpayment Due to Leaving the UK
If you move abroad before the tax year ends, you might be due a refund for the months you didn’t work in the UK.
Example: John moved to Canada in October 2024, but his UK employer continued PAYE deductions until April 2025. After filing a P85 form, he claimed a £1,200 refund.
How to Check if You Are Owed a Tax Refund
1. Use HMRC’s Online Tax Checker
Visit GOV.UK’s tax refund checker to see if you’re eligible.
2. Log Into Your Personal Tax Account
Go to HMRC’s Personal Tax Account and check your tax payments vs. what you owe.
3. Check Your Tax Code
Your tax code appears on your payslip or P60. If it looks incorrect (e.g., BR, D0, or an emergency tax code like 1257L M1), you may have overpaid.
4. Look at Your P800 or Simple Assessment Letter
HMRC issues P800 tax calculation letters if you’ve overpaid PAYE tax. If you get one, you can claim online or via bank transfer.
5. Call HMRC
If you’re unsure, call HMRC’s helpline at 0300 200 3300 to check your status.
What Happens Next?
If you’re due a refund, HMRC typically pays it within 4-12 weeks.
You might receive the refund via bank transfer, cheque, or payroll adjustment.
If you don’t claim a refund, HMRC holds it for four years before it expires.
Step-by-Step Guide to Claiming a Tax Refund in the UK
Now that you understand how tax refunds work and who is eligible, it's time to walk through the process of claiming a refund step by step. If HMRC owes you money, you don’t want to leave it sitting there!
In this section, we’ll cover:
✅ The exact steps to claim a refund
✅ How to claim for different tax situations (PAYE, self-assessment, CIS, pensions, etc.)
✅ The documents you need to apply
✅ How long refunds take and what to do if it's delayed
Let’s dive in.
Step 1: Identify How You Overpaid Tax
Before you start your refund claim, figure out why you overpaid tax. Different situations require different claims:
Situation | How to Claim a Refund |
PAYE employees (wrong tax code, emergency tax, job changes) | HMRC automatically issues a P800 tax calculation or you can claim online via GOV.UK. |
Self-employed (Self Assessment overpayment) | File your Self Assessment tax return and HMRC will adjust the refund. |
Construction workers (CIS deductions) | Claim via Self Assessment or a CIS tax refund specialist. |
Pensioners (overpaid tax on pension withdrawals) | Use form P55, P53, or P50Z, depending on your situation. |
People leaving the UK before tax year ends | Fill out P85 form on GOV.UK. |
Work expenses (uniform, travel, tools, professional fees, etc.) | Claim via HMRC’s online tool. |
Refund for previous years | Claims can go back four tax years. Apply using a P800 letter or via Self Assessment. |
Once you know which type of refund applies, move on to Step 2.
Step 2: Gather the Required Documents
The documents you need depend on your tax situation. Here’s what you might need:
✅ For PAYE Employees
P60 (year-end tax summary from your employer)
P45 (if you’ve left a job during the tax year)
Payslips (if there were irregular tax deductions)
P800 tax calculation (if HMRC sent one)
✅ For Self-Employed & CIS Workers
Self Assessment tax return (SA100)
CIS deduction statements (if in construction)
Business expense receipts
Bank statements (to verify payments to HMRC)
✅ For Pensioners
Pension withdrawal statement (P45 from pension provider)
Bank details (for HMRC to issue a refund)
✅ For Employees Claiming Work Expenses
Receipts for work-related expenses (tools, uniform, travel, etc.)
Mileage logs (if claiming vehicle tax relief)
Union or professional membership fee receipts
If you don’t have a required document, you can request copies from your employer, pension provider, or HMRC.
Step 3: Submit Your Claim to HMRC
The process varies depending on your situation. Here’s how to apply for each case:
1. Claiming an Income Tax Refund (PAYE Employees & Pensioners)
Best method: Online via GOV.UK’s refund portal

🕒 Refund time: If HMRC owes you money, they usually process refunds within 1-4 weeks after filing.

Common Mistakes That Delay Tax Refunds & How to Avoid Them
Now that we’ve covered how to check if you’re owed a tax refund and how to claim it, it’s time to discuss something crucial: what can go wrong with your tax refund claim?
Every year, thousands of UK taxpayers face delays, rejections, or unnecessary complications when trying to get their tax rebate. The frustrating part? Many of these issues are completely avoidable.
In this section, we’ll explore:
✅ The most common mistakes people make when claiming refunds
✅ Why HMRC might delay or reject your tax refund
✅ How to prevent errors that slow down the process
✅ Tips for ensuring a smooth and successful claim
Let’s dive in.
Common Mistakes That Delay Tax Refunds
When claiming a tax refund, even a small mistake can cause unnecessary delays. Here are some of the most common errors taxpayers make:
1. Using the Wrong Tax Code
One of the biggest reasons for tax overpayment is having the wrong tax code. If you claim a refund but don’t correct your tax code, you might continue overpaying in future pay periods.
🛑 Mistake:
Not checking if your PAYE tax code is correct before submitting a refund claim.
Assuming HMRC automatically corrects tax codes after a refund.
✅ How to fix it:
Check your tax code on your payslip, P60, or online HMRC account.
Common incorrect codes to watch for:
BR (Basic Rate – used when you have more than one job, but sometimes applied wrongly)
D0 or D1 (Higher or Additional Rate tax, even when you shouldn't be in those brackets)
1257L W1/M1 (Emergency tax code)
If you see an incorrect tax code, contact HMRC at 0300 200 3300 to get it fixed.
2. Submitting an Incomplete Claim Form
HMRC is very strict about tax refund applications. If your form is incomplete, it will be rejected or delayed while they request more details.
🛑 Mistake:
Forgetting to include bank details (for refunds via bank transfer).
Missing out supporting documents like P60s, P45s, or receipts.
Using the wrong form (e.g., submitting a P85 when you need a P50Z).
✅ How to fix it:
Triple-check your claim form before submitting.
Make sure you include:
✔ Your National Insurance number
✔ Your employer or pension provider’s details
✔ Your P60/P45 (if relevant)
✔ Receipts for work-related expenses (if applicable)
✔ Your bank details (if requesting a bank transfer refund)
3. Not Claiming for Previous Tax Years
Did you know? You can claim tax refunds for up to four previous tax years! Many taxpayers don’t realise this and miss out on money owed to them.
🛑 Mistake:
Assuming refunds are only for the current tax year.
Forgetting to check if you've overpaid in previous years.
✅ How to fix it:
You can claim back tax refunds for the past four tax years.
To check if you were overtaxed in previous years:
Log into HMRC’s Personal Tax Account.
Look at your tax paid vs. income for each year.
If you find any overpayment, you can apply for a refund by contacting HMRC or submitting a claim online.
4. Failing to Keep Copies of Key Documents
HMRC might ask you for additional information before approving your refund. If you don’t have the necessary records, your claim could be delayed or denied.
🛑 Mistake:
Throwing away important documents like P60s, P45s, payslips, and expense receipts.
Not having proof of mileage, professional expenses, or business costs.
✅ How to fix it:
Keep digital and paper copies of all tax-related documents.
For expenses, store receipts, invoices, and mileage logs for at least four years.
Use apps like HMRC’s expenses tracker or an Excel sheet to keep records.
Tip: If you've lost your P60 or P45, ask your employer or pension provider for a replacement.
5. Waiting Too Long to Chase a Refund
Tax refunds typically take 2-12 weeks to process, but delays happen—especially during peak tax season (April–July). If you haven’t received your refund, don’t just wait indefinitely.
🛑 Mistake:
Assuming HMRC will update you automatically.
Waiting for months without following up.
✅ How to fix it:
If it’s been more than 8 weeks, contact HMRC at 0300 200 3300.
Use the ‘Where’s My Reply?’ tool to track your claim status.
If HMRC says they’ve processed the refund, check your bank and tax account for payment updates.
6. Claiming Through Scammers or Dodgy Companies
Many companies offer to get you a tax refund—but some charge huge fees or scam people out of their money.
🛑 Mistake:
Using unofficial tax refund agents who take 30-50% of your refund as commission.
Clicking on fake HMRC emails asking for personal details.
Believing text messages or WhatsApp messages claiming you’re owed a refund.
✅ How to fix it:
Always use official HMRC channels:
HMRC phone support (0300 200 3300)
Be wary of third-party refund services that charge high commissions.
If you get a suspicious email or message, report it to phishing@hmrc.gov.uk.
Warning: HMRC never asks for personal details via text, WhatsApp, or email.
How to Prevent Overpaying Tax in the First Place
Want to avoid overpaying tax altogether? Here are some smart strategies:
✅ Check Your Tax Code Regularly
Keep an eye on your payslips, P60s, and P45s.
If your tax code seems wrong, update it immediately with HMRC.
✅ Claim Work-Related Expenses Every Year
If you spend money on uniforms, tools, mileage, or professional fees, claim tax relief annually.
✅ Use an Accountant or Tax Software (If Self-Employed)
A tax professional can spot overpayments early.
Online tax software like FreeAgent, TaxScouts, or QuickBooks helps track deductions.
✅ Set Up a Personal Tax Account with HMRC
Log into GOV.UK’s Personal Tax Account to track your tax payments.
You can see if you’re due a refund before waiting for a P800 letter.
What to Do if Your Tax Refund is Delayed or Rejected
You have checked your eligibility, submitted your tax refund claim, and now you are waiting for the money to arrive. But what if weeks pass and nothing happens?
Many taxpayers in the UK experience delays in receiving their tax refund or, in some cases, get their claim rejected by HMRC. This can be frustrating, especially if you are owed a significant amount of money.
In this section, we will cover:
✅ How long different types of tax refunds take
✅ Common reasons why tax refunds get delayed
✅ What to do if HMRC rejects your tax refund claim
✅ How to appeal an HMRC decision and resolve disputes
How Long Does a Tax Refund Take?
The time it takes to receive your tax refund depends on how you applied and what type of refund you are claiming. Here is an estimate based on HMRC’s processing times:
Type of Tax Refund | Estimated Processing Time |
PAYE overpayment (P800 letter) | 1-4 weeks |
PAYE overpayment (online claim) | 1-4 weeks |
Self Assessment tax refund | 1-4 weeks after submitting return |
CIS tax refund (Construction Industry Scheme) | 2-6 weeks |
Pension tax refund (P55, P53, P50Z) | 4-8 weeks |
Work expenses tax relief | 4-8 weeks |
Paper refund applications | 6-12 weeks |
Most refunds are processed within four weeks, but some claims take longer, especially if HMRC needs to verify additional details.
Why Is Your Tax Refund Delayed?
If you have been waiting longer than the estimated time, one or more of the following issues may be causing the delay.
1. HMRC Needs to Verify Your Information
If you are claiming a large refund or your claim is unusual, HMRC may carry out additional checks before releasing the money.
What you can do:
Call HMRC at 0300 200 3300 to check your claim’s progress.
Log into HMRC’s Personal Tax Account to see if there are any updates.
If HMRC requests further information, respond as soon as possible.
2. Your Tax Return Contains Errors or Missing Information
If you made a mistake on your tax return or refund application, HMRC may put your claim on hold until you correct it.
What you can do:
Double-check the information in your claim.
If you notice an error, update it by logging into your HMRC Self Assessment account or calling HMRC.
Make sure you submitted all required documents, such as P60s, P45s, and CIS statements.
3. HMRC Has Outdated Bank Details for You
If you changed your bank account recently, HMRC might have tried to send your refund to your old account, causing the payment to fail.
What you can do:
Update your bank details in your Personal Tax Account.
If your refund was sent to a closed account, contact HMRC so they can reissue it.
4. Your Refund Was Issued by Cheque (Which Takes Longer)
If you opted to receive your refund by cheque, it will take longer than a bank transfer. HMRC sends cheques by post, which can add delays.
What you can do:
If you were expecting a cheque but did not receive it, contact HMRC.
Consider switching to a bank transfer for faster processing in the future.
5. HMRC Processing Backlogs
During busy periods, such as April to July (tax return season), HMRC experiences high volumes of refund requests, which can slow down processing times.
What you can do:
Be patient, but if you have waited more than eight weeks, call HMRC for an update.
Use the HMRC ‘Where’s My Reply?’ tool to check estimated response times.
What to Do if HMRC Rejects Your Tax Refund Claim
Sometimes, HMRC may reject a tax refund claim if they believe you are not entitled to a refund or if there were errors in your application. If this happens, do not panic. You may be able to correct the issue or challenge HMRC’s decision.
1. Understand Why Your Claim Was Rejected
If HMRC rejects your refund, they will send you a letter explaining the reason. Common reasons include:
You did not overpay tax, so no refund is due.
Your claim was missing documents or incorrect information.
You claimed a tax relief you were not eligible for.
You missed the deadline to claim a refund.
What you can do:
Read HMRC’s response carefully and see if you can correct the issue.
If you disagree with their decision, you have the right to appeal.
2. How to Appeal an HMRC Tax Refund Decision
If you believe HMRC made a mistake in rejecting your claim, you can appeal the decision.
Step 1: Contact HMRC First: Before filing a formal appeal, try to resolve the issue directly with HMRC by:
Calling 0300 200 3300 and asking for a review of your case.
Sending a written request for reconsideration, including supporting documents.
Step 2: Submit a Formal Appeal (If Needed): If HMRC still refuses your refund after an informal review, you can formally appeal by completing a form SA370 and sending it to HMRC.
Step 3: Take Your Case to a Tribunal (As a Last Resort): If your appeal is denied, you can take your case to an independent tax tribunal. This is rare but an option if HMRC refuses to correct a clear mistake.
How to Escalate a Complaint to HMRC
If your tax refund is delayed for months or you believe HMRC is handling your case unfairly, you can file a complaint.
Step 1: Submit a Complaint to HMRC: You can file a complaint via:
Online: HMRC Complaints Page
Phone: Call 0300 200 3300 and ask to speak to a complaints officer.
Post: Write to HMRC at HM Revenue & Customs, BX9 1AS, United Kingdom.
Step 2: Contact the Adjudicator’s Office (If HMRC Does Not Respond): If HMRC does not resolve your complaint, you can escalate it to the Adjudicator’s Office, which reviews disputes between taxpayers and HMRC.
Step 3: Contact Your MP (As a Last Resort): If all else fails, you can ask your Member of Parliament (MP) to intervene. MPs can raise tax refund delays with HMRC directly on behalf of their constituents.
Maximising Your Tax Refunds and Avoiding Future Overpayments
We have now covered how to check if you are owed a tax refund, how to claim it, what to do if it is delayed or rejected, and how to appeal a decision. In this final section, we will focus on how to make the most of your tax refunds and how to prevent overpaying tax in the future.
While getting a tax refund can feel like a bonus, the reality is that it means you have paid more tax than necessary. Ideally, your tax should be calculated correctly from the start so that you are not lending money to HMRC interest-free. By following a few simple strategies, you can reduce the chances of overpaying and ensure you receive any refunds you are entitled to as quickly as possible.

✅ How tax refunds affect your overall finances
✅ Smart ways to use your tax refund
✅ How to prevent overpaying tax in the future
✅ Final expert tips for a smooth refund process
How Tax Refunds Affect Your Finances
While tax refunds are welcome, they are not truly “extra money.” It is simply your own money being returned after being overpaid to HMRC. Understanding how refunds impact your finances can help you manage your money better.
1. Tax Refunds Are Not Additional Income
A refund is not a bonus or a reward from the government. It is simply a correction of an overpayment.
If you rely on refunds every year, it may be a sign that your tax code or financial planning needs adjustment.
2. Tax Refunds Do Not Count as Taxable Income
HMRC refunds are not considered taxable income, so they do not increase your tax bill.
If you receive a large refund, you do not need to declare it on your Self Assessment.
3. Refunds Can Affect Benefits and Tax Credits
If you receive Universal Credit, Working Tax Credit, or Child Tax Credit, a large refund may temporarily affect your payments.
It is important to report any changes in your financial situation to the Department for Work and Pensions (DWP) or HMRC if required.
Smart Ways to Use Your Tax Refund
Once your refund arrives, it is worth considering how to use it effectively. Many people view refunds as extra spending money, but there are smarter ways to make the most of them.
1. Pay Off High-Interest Debt
If you have credit card debt, personal loans, or overdrafts, using your refund to reduce your balance can save you money on interest.
2. Build or Boost Your Emergency Fund
If you do not already have an emergency savings fund, consider putting your refund aside in a high-interest savings account.
3. Invest in Pension Contributions
Contributing extra to your workplace or private pension could give you additional tax benefits, helping you reduce future tax liabilities.
4. Claim Work-Related Expenses for Next Year
If you regularly incur work-related expenses (such as tools, uniforms, or mileage), consider using your refund to cover future expenses that you can later claim tax relief on.
5. Make an Overpayment on Your Mortgage
If your mortgage allows overpayments, you could reduce your overall interest by making an additional payment using your tax refund.
How to Avoid Overpaying Tax in the Future
Rather than waiting for HMRC to return your money after an overpayment, it is better to ensure you pay the correct tax from the start. Here are some key steps to help prevent overpayment.
1. Check Your Tax Code Every Year
Your tax code determines how much tax is deducted from your salary. An incorrect tax code is one of the most common reasons for overpayment.
Look at your payslip, P60, or P45 to find your current tax code.
The most common tax code for 2024/25 is 1257L, meaning you get a £12,570 tax-free personal allowance.
If you notice an incorrect code (e.g., BR, D0, or an emergency code like 1257L M1), contact HMRC to fix it.
How to check:
Visit HMRC’s online tax account.
Call HMRC at 0300 200 3300 if your tax code seems incorrect.
2. Update HMRC When Your Income Changes
If you experience a major change in income, HMRC needs to know to ensure you are taxed correctly.
Report changes if:
You switch from full-time to part-time work or vice versa.
You start receiving pension payments while still working.
You stop being self-employed and return to PAYE employment.
If your income drops significantly but your tax code is still based on your previous salary, you could overpay tax unnecessarily.
3. Keep Good Records for Work Expenses
If you claim tax relief on job-related expenses, make sure you keep accurate records so you do not miss out on future refunds.
Save receipts for tools, uniforms, mileage logs, and professional fees.
If you work from home, track utility bills for tax-deductible portions.
Submit claims annually via HMRC’s work expenses tool.
4. Consider Making Voluntary National Insurance Contributions (If Needed)
If you take a career break, work abroad, or earn below the NI threshold, you might underpay National Insurance, which can affect your state pension.
Check your NI record via GOV.UK.
If you have gaps, consider making voluntary contributions to protect your entitlement.
5. File Your Self Assessment on Time
If you are self-employed or a landlord, filing your Self Assessment tax return early can help you avoid tax overpayments and unexpected tax bills.
Key deadlines:
Paper tax return deadline: 31 October
Online tax return deadline: 31 January
Payments on Account: 31 July (if applicable)
If your income varies, adjusting your Payments on Account can prevent overpaying in advance.
Final Expert Tips for a Smooth Tax Refund Process
1. Sign Up for HMRC’s Personal Tax Account
This allows you to check your tax payments, tax code, and refund status in real-time.
2. Keep Copies of All Tax Documents
Save digital and paper copies of P60s, P45s, self-assessment returns, and refund claim forms.
3. Be Cautious of Tax Refund Scams
HMRC never sends refunds via text or email. If you receive a suspicious message, report it to phishing@hmrc.gov.uk.
4. Set Reminders for Tax Deadlines
Avoid missing refund claim deadlines by setting up calendar reminders for tax return submissions.
5. Contact HMRC if You Are Unsure
If you have doubts about your tax situation, call HMRC for clarification before submitting a claim.
Checking if you are owed a tax refund and claiming what is rightfully yours can put extra money in your pocket. However, prevention is always better than correction—by staying on top of your tax code, income records, and eligible deductions, you can avoid overpaying in the first place.
If you believe you have overpaid tax, take action today by checking your records and submitting a claim if necessary. Even if the refund is small, it is your money, and there is no reason to let it sit with HMRC longer than necessary.
For the latest updates on tax refunds and allowances, visit GOV.UK or speak to a tax professional if you need personalised advice.
By following the strategies in this guide, you can ensure that you only pay the tax you truly owe—and not a penny more.
Summary of Key Points on Checking if You Are Owed a Tax Refund in the UK
A tax refund occurs when you have overpaid tax due to incorrect tax codes, emergency tax, overestimated payments, or work-related expense claims.
You can check if you are owed a refund by logging into your HMRC Personal Tax Account, reviewing your tax code, or using HMRC’s online tax refund tool.
Tax refunds apply to various taxpayers, including PAYE employees, self-employed individuals, pensioners, construction workers (CIS), and those leaving the UK mid-tax year.
To claim a refund, gather necessary documents such as your P60, P45, payslips, CIS deduction statements, or Self Assessment tax return, and submit a claim online, by phone, or by post.
HMRC typically processes tax refunds within 1-4 weeks for online claims, 2-6 weeks for CIS refunds, and up to 12 weeks for paper applications.
Common reasons for delayed refunds include missing information, incorrect tax codes, outdated bank details, processing backlogs, or HMRC conducting additional verification checks.
If HMRC rejects your tax refund claim, you can request a review, submit an appeal using form SA370, or escalate the issue to a tax tribunal if necessary.
To prevent overpaying tax in the future, regularly check and update your tax code, report income changes to HMRC, and keep detailed records of work-related expenses.
Using a tax refund for debt repayment, emergency savings, pension contributions, or work-related purchases can provide long-term financial benefits.
Staying informed about tax rules, filing Self Assessment returns on time, and avoiding refund scams ensures a smooth and secure tax refund process.

5. Q: Can you receive a tax refund if you left the UK but did not submit a P85 form?
A: Yes, you can still claim a tax refund for overpaid tax if you left the UK, but you must submit a P85 form to HMRC to process your claim. Refunds can be backdated for up to four years.
6. Q: How does receiving a tax refund affect your student loan repayments?
A: If you overpaid tax and receive a refund, it does not reduce your student loan balance. However, if you overpaid student loan deductions, you can request a separate refund from the Student Loans Company.
7. Q: Can you get a tax refund if you were on an emergency tax code for only a short period?
A: Yes, even if you were on an emergency tax code for a few weeks, you may have overpaid tax and could be eligible for a refund. HMRC typically corrects this automatically, but you can request a refund manually if necessary.
8. Q: What happens to your tax refund if you owe HMRC money for unpaid taxes?
A: If you have outstanding tax debts, HMRC may offset your refund against your unpaid tax before issuing any remaining amount. You will receive a letter explaining the adjustment.
9. Q: Can you claim a tax refund if you only worked for part of the tax year?
A: Yes, if you worked for only part of the tax year and earned below your personal allowance (£12,570 for 2024/25), you may be due a refund for overpaid tax.
10. Q: Is it possible to track your tax refund status with HMRC?
A: No, HMRC does not provide a real-time tracking tool for refunds. However, you can check your Personal Tax Account or call 0300 200 3300 to ask about the status of your claim.
11. Q: Can you receive a tax refund if your employer went out of business before paying you?
A: Yes, but you may need to contact HMRC with your final payslip or P45 to verify your income and tax deductions. If your employer did not report your earnings, the process may take longer.
12. Q: Does receiving a tax refund mean you will be taxed more in the future?
A: No, a tax refund is simply a correction of overpaid tax and does not increase your tax rate or affect future tax calculations.
13. Q: What happens if your tax refund is sent to a closed bank account?
A: If HMRC tries to deposit a refund into a closed account, the bank will reject the payment, and HMRC will issue a cheque or request updated bank details from you.
14. Q: Can you claim a tax refund if you were self-employed and made advance tax payments (Payments on Account)?
A: Yes, if your final tax liability is lower than the Payments on Account you made, HMRC will issue a refund for the excess amount once you submit your Self Assessment tax return.
15. Q: Can you claim a tax refund for pension contributions made through salary sacrifice?
A: No, if you contribute to a pension through a salary sacrifice scheme, your taxable income is reduced before tax is applied, so no additional refund is due.
16. Q: Do you need to declare a tax refund on a mortgage or loan application?
A: No, tax refunds are not considered regular income and do not need to be included on mortgage or loan applications.
17. Q: Can HMRC reverse a tax refund after issuing it?
A: Yes, if HMRC finds that a refund was issued in error, they can request repayment. If you receive an unexpected refund, check with HMRC before spending the money.
18. Q: What should you do if you receive a tax refund cheque but have lost it?
A: If you lose a tax refund cheque, you should contact HMRC immediately to request a reissue. It may take several weeks for a replacement cheque to be sent.
19. Q: Can you get a tax refund if you were on statutory sick pay (SSP) or maternity leave?
A: Yes, if your income was reduced while receiving SSP or maternity pay, you may have overpaid tax and could be eligible for a refund.
20. Q: Can you get a tax refund if you work abroad but still pay UK tax?
A: If you are working abroad but continue to pay UK tax, you may be eligible for a refund or tax relief under a double taxation agreement. You should check whether you qualify for tax residency exemptions.
