Introduction to HMRC Tax Refund Letters
Tax refunds are an important concern for millions of UK taxpayers, whether they are employees, self-employed individuals, or business owners. If you have overpaid tax, you might be eligible for a refund, but the process of receiving it can sometimes be confusing. One of the most common questions people ask is: “Does HMRC send letters about tax refunds?” The answer is yes, but with certain conditions.
HM Revenue & Customs (HMRC) does send official letters regarding tax refunds, primarily in the form of a P800 tax calculation letter or a Simple Assessment letter. However, taxpayers need to be cautious because HMRC does not typically notify individuals of tax refunds via email, text message, or phone calls—common methods used by scammers. Understanding how HMRC communicates and what steps to take when you receive such a letter is crucial for ensuring you receive your refund securely and promptly.
In this article, we’ll explore:
How and when HMRC sends tax refund letters
The different types of tax refunds available
The timeline and process for claiming a tax refund
By the end of this article, you’ll have a clear understanding of how HMRC handles tax refunds and what to do if you’re expecting one.
How Does HMRC Notify You About a Tax Refund?
1. The P800 Tax Calculation Letter
The P800 tax calculation letter is the most common form of official communication from HMRC regarding tax refunds. It is issued when HMRC finds that you have paid too much tax through Pay As You Earn (PAYE).
Who Gets a P800 Letter?
You may receive a P800 letter if:
You had multiple jobs and too much tax was deducted.
You were on the wrong tax code.
You had work-related expenses that weren’t accounted for.
You received untaxed savings interest or benefits incorrectly reported.
When Does HMRC Send P800 Letters?
HMRC typically sends out P800 letters between June and October following the end of the tax year (5 April). The letter details whether you owe tax or are due a refund.
How Do You Claim Your Refund?
If you are due a refund, the letter will direct you to claim it online via the official GOV.UK tax refund portal (check the link here). If you don’t claim online within 21 days, HMRC will automatically send a cheque within 6 weeks.
2. The Simple Assessment Letter
Another way HMRC informs taxpayers of tax refunds is through a Simple Assessment letter. This method is used when HMRC calculates your tax bill automatically based on your income and allowances.
Who Gets a Simple Assessment Letter?
Pensioners who have underpaid or overpaid tax.
Individuals who owe tax that cannot be deducted through PAYE.
Those with high earnings or multiple sources of income.
If you’re due a refund, HMRC will either issue the refund automatically or ask you to provide further information to process it.
3. HMRC Letters for Self-Assessment Taxpayers
For those who file a Self Assessment tax return, HMRC does not usually send out tax refund letters. Instead:
If you have overpaid tax, you will see a credit balance in your online Self Assessment account.
You can request a refund online through your HMRC account.
If you have set up a Direct Debit, HMRC may refund the overpaid amount automatically.
What Are the Different Types of Tax Refunds in the UK?
Tax refunds aren’t just for those who have paid too much through PAYE or Self Assessment. There are multiple scenarios where individuals and businesses may be eligible for a tax refund.
Type of Refund | Who Can Claim? | How to Claim? |
PAYE Tax Refund | Employees who overpaid tax due to incorrect tax codes or multiple jobs | Wait for a P800 letter or request a tax calculation from HMRC |
Work-Related Expense Refund | Employees who pay for uniforms, travel, or professional subscriptions | Claim via HMRC’s online service or form P87 |
Self-Employed Tax Refund | Self-employed individuals who overpaid tax or claimed expenses incorrectly | Adjust in the Self Assessment tax return |
Pension Tax Refund | Pensioners who paid excess tax on withdrawals | HMRC automatically adjusts in future payments or sends a P800 |

Savings & Investment Tax Refund | People who overpaid tax on savings interest | Usually refunded automatically via tax code adjustments |
Construction Industry Scheme (CIS) Refund | Contractors and subcontractors in the construction sector | File a Self Assessment tax return |
Marriage Tax Allowance Refund | Couples where one partner earns below the tax threshold | Apply online on GOV.UK |
Each of these refunds has a different process and timeline, making it essential to check your tax situation regularly.
How Long Does It Take to Receive a Tax Refund?
The time it takes to get your tax refund depends on how HMRC processes your claim.
Method of Refund | Processing Time |
Online bank transfer (P800) | 5 working days |
Cheque via post | 6 weeks |
Self Assessment Refund (online request) | Up to 4 weeks |
Automatic Refund (PAYE) | Processed between June and October |
If you haven’t received your refund within the expected time, you can contact HMRC’s tax refund department through the official HMRC helpline at 0300 200 3300.
What to Do If You Haven’t Received Your Tax Refund Letter?
If you believe you’re due a tax refund but haven’t received a letter, here’s what you should do:
Check Your HMRC Online AccountLog in to your Personal Tax Account on GOV.UK to see if there’s any update on your tax refund.

Beware of Tax Refund Scams: How to Spot Fake HMRC Letters
1. How Do Tax Refund Scams Work?
Tax refund scams are on the rise in the UK, with fraudsters impersonating HMRC to trick taxpayers into providing personal and banking information. These scams usually come in the form of:
Fake HMRC letters
Emails claiming you have a tax refund
Text messages with refund links
Phone calls from scammers pretending to be HMRC agents
The scammer’s goal is to steal money or personal information, so it’s crucial to verify every tax-related communication before taking action.
2. How to Identify a Genuine HMRC Letter vs. a Scam Letter
A real tax refund letter from HMRC will:
✅ Be printed on official HMRC letterhead with the HMRC logo.
✅ Include your full name, National Insurance (NI) number, and tax reference number.
✅ Direct you to claim your refund only through the official GOV.UK website (never via email links or phone calls).
✅ Clearly explain why you are receiving a refund and how it was calculated.
✅ Never request personal or financial information via email, text, or phone.
A scam tax refund letter may:
❌ Have spelling or grammar mistakes.
❌ Use threatening language (e.g., "Your refund will be cancelled if you don’t act immediately").
❌ Ask you to visit an unfamiliar website or click on a link.
❌ Request your bank details, PIN, or password over the phone or email.
Example of a Scam Tax Refund Email
📩 Subject: Urgent! You have an outstanding tax refund!
📌 Message: Dear customer, you are eligible for a £756.32 tax refund. Click here to claim: fake-link.com
🚨 Warning: HMRC never sends tax refund notifications via email or text. If you receive one, do not click any links and report it to HMRC at phishing@hmrc.gov.uk.
Common Mistakes That Delay Your Tax Refund
Even if you're entitled to a tax refund, some common errors can cause unnecessary delays. Here are the biggest mistakes to avoid:
1. Providing Incorrect Bank Details
If you’ve requested a refund via bank transfer, ensure your sort code and account number are correct. A simple error can result in significant delays, as HMRC will need to reprocess your claim.
2. Not Updating Your Address with HMRC
If HMRC sends a refund cheque to an old address, you’ll have to wait weeks for it to be reissued. Update your contact details through your Personal Tax Account on GOV.UK.
3. Claiming a Refund for the Wrong Tax Year
Many taxpayers mistakenly submit refund requests for the wrong year. Check your P800 letter carefully to confirm which tax year the refund applies to.
4. Failing to Keep Records
HMRC may ask for supporting documents when processing tax refunds. Keep records of payslips, P60s, P45s, work expenses, and tax return confirmations.
5. Missing the Deadline for Refund Claims
Tax refunds must usually be claimed within four years of the end of the tax year. For example, to claim a refund for the 2020/21 tax year, you have until 5 April 2025.
Tax Year | Claim Deadline |
2020/21 | 5 April 2025 |
2021/22 | 5 April 2026 |
2022/23 | 5 April 2027 |
2023/24 | 5 April 2028 |
How Businesses Can Claim Tax Refunds
1. Corporation Tax Overpayments
If a company overpays Corporation Tax, it can request a refund from HMRC. Overpayments often happen due to:
Miscalculations in estimated tax payments
Changes in reported profits
Utilising tax reliefs after filing the return
How to Claim a Corporation Tax Refund:
Submit an amended tax return via your company’s HMRC online account.
Call HMRC’s Corporation Tax Helpline at 0300 200 3410.
Refunds are usually processed within 28 days.

Their VAT expenses exceed their VAT sales (common for startups and exporters).
They paid VAT on items that should have been zero-rated.
They are claiming VAT relief on bad debts.
How to Claim a VAT Refund:
File your VAT return on HMRC’s Making Tax Digital (MTD) system.
If HMRC owes you money, the refund is usually paid within 10 working days.
3. PAYE & National Insurance Refunds for Businesses
Employers may receive refunds if they:
Overpaid PAYE tax or National Insurance (NI) for employees.
Claimed Employment Allowance but weren’t credited properly.
Paid excess tax due to an administrative error.
How to Claim:
Employers can check overpayments on their HMRC PAYE online account.
Refunds are usually processed within 14 working days.
What to Do If Your Tax Refund Is Delayed

Summary
Beware of tax refund scams—HMRC never emails or calls about refunds.
Avoid common mistakes like incorrect bank details or missing deadlines.
Businesses can claim tax refunds on Corporation Tax, VAT, and PAYE overpayments.
If your refund is delayed, check your HMRC account or contact HMRC.
How to Maximise Your Tax Refund
Many taxpayers miss out on potential refunds simply because they don’t know what they can claim. Here are some ways to increase your tax refund legally.
1. Claim All Work-Related Expenses
If you spend money on job-related costs and your employer hasn’t reimbursed you, you might be eligible for a tax refund.
Some common claims include:
Uniforms & Work Clothing – If you’re required to wear a uniform and wash it yourself, you can claim a tax rebate.
Professional Fees & Subscriptions – Membership fees for certain professional organisations (e.g., CIMA, ACCA, RCN) can be deducted.
Travel Costs – If you travel for work (excluding commuting), you may claim mileage and public transport costs.
You can submit claims through HMRC’s P87 form online or by post.
2. Use the Marriage Allowance
If one spouse earns below the Personal Allowance threshold (£12,570 for 2024/25), they can transfer £1,260 of their tax-free allowance to their partner, saving up to £252 per year.
Claims can be made on GOV.UK and backdated for up to four years, potentially resulting in a larger refund.
3. Check Your Tax Code
An incorrect tax code could mean you’re overpaying tax. You can find your code on your payslip or check it online via HMRC’s tax code checker. If it's wrong, request a correction to avoid future overpayments.
4. Claim Back Overpaid National Insurance
If you worked multiple jobs or paid National Insurance at the wrong rate, you could be entitled to a refund. You’ll need to contact HMRC and provide your employment details.
How to Track Your Tax Refund in Real-Time
Once you’ve submitted a refund claim, tracking it can prevent unnecessary delays.
Tracking Method | How to Check | Expected Timeframe |
HMRC Online Account | Log in to GOV.UK’s Personal Tax Account | Instant status update |
HMRC App | Download the app and check under "Tax Refunds" | Instant status update |
Phone Helpline | Call 0300 200 3300 | Response time varies |
Cheque Tracking | If you’re waiting for a cheque, contact HMRC | Usually arrives within 6 weeks |
For Self Assessment refunds, you can also check your Self Assessment account. If a refund is being processed, it will show a credit balance.
Legal Tax Reliefs That Reduce Your Tax Bill
Apart from refunds, you can also reduce future tax payments by claiming legitimate tax reliefs.
1. Tax Relief for Self-Employed Workers
If you’re self-employed, you can deduct business expenses from your taxable income, reducing the tax owed. Eligible expenses include:
Office rent, utility bills, and home office costs
Business travel and mileage
Marketing and advertising expenses
Equipment, tools, and work-related software
Make sure to keep receipts and records for at least six years in case HMRC requests proof.
2. Rent a Room Scheme
If you rent out a furnished room in your home, you can earn up to £7,500 tax-free under the Rent a Room Scheme. If you earn more, you’ll need to declare it on your Self Assessment tax return.
3. Capital Gains Tax Allowance
If you sell an asset like a property or shares, you may be liable for Capital Gains Tax. However, you can take advantage of:
Annual exemption (£3,000 for 2024/25)
Private Residence Relief if it was your main home
Business Asset Disposal Relief for small business owners
These allowances can help reduce your tax bill significantly.
4. Pension Contributions and Gift Aid
Contributing to a pension or donating to charity through Gift Aid can reduce your taxable income. Higher-rate taxpayers can claim additional relief through Self Assessment.
For example, if you donate £100 to charity, it’s treated as £125 (due to Gift Aid). If you’re a 40% taxpayer, you can claim £25 back through Self Assessment.
What to Do If HMRC Rejects Your Tax Refund Claim?
Sometimes, HMRC may reject a refund request due to errors or missing information. Here’s what to do if that happens:
Check the Reason – HMRC will usually provide a reason for the rejection. It could be due to incorrect tax calculations or missing paperwork.
Gather Evidence – If your claim is legitimate, provide supporting documents like payslips, bank statements, or expense receipts.
Request a Review – You can challenge HMRC’s decision by requesting a review. This can be done online, by phone, or in writing.
Appeal to the Tax Tribunal – If you’re still dissatisfied, you can escalate your case to the First-tier Tax Tribunal.
Most rejected claims can be resolved by correcting mistakes or providing additional information.
