You may be owed a tax rebate from HMRC if you’ve overpaid income tax. UK taxpayers can claim back tax for employment expenses, incorrect tax codes, or emergency tax overpayments. You can backdate claims for up to 4 years.

£100-£600 for 4 years (nurses, retail workers, police officers)
£500-£4,000 per year for business travel at 45p/mile
£252 per year (transfer £1,260 of personal allowance to spouse)
20-45% of subscription costs (unions, professional bodies)
20-45% of purchase costs (tradespeople)
A tax rebate (also called a tax refund) is money HMRC returns to you when you’ve paid more income tax than you owe. This happens because the UK tax system requires you to claim tax reliefs yourself – HMRC doesn’t automatically refund most overpayments.
The most common reasons for tax rebates include:
You can claim a tax rebate if you:
Self-employed? Our accountant directory can help you find a qualified professional to maximise your tax position, or explore accounting software options to manage your finances efficiently.
If you wear a uniform or specialist clothing for work and you’re responsible for cleaning, repairing or replacing it, you can claim a flat rate allowance based on your profession.
How much you can claim:
Over 4 years, this typically amounts to £100-£600 in total tax refunds.
If you use your own vehicle for work travel (not your commute to your regular workplace), you can claim tax relief on mileage. HMRC’s approved rate is 45p per mile for the first 10,000 business miles.
If your employer pays less than 45p per mile (or doesn’t reimburse you at all), you can claim tax back on the difference.
Example: If you drive 3,000 business miles with no reimbursement, you can claim 3,000 × 45p = £1,350. At basic rate tax (20%), your tax refund would be £270 per year, or £1,080 over 4 years.
If you’re married or in a civil partnership, you may be able to transfer £1,260 of your personal allowance to your spouse or civil partner, provided one of you is a non-taxpayer and the other is a basic rate taxpayer.
Both partners must have been born after 5th April 1935. One partner must earn less than £12,570 (the personal allowance) and the other must earn between £12,571 and £50,270 (basic rate tax band).
This gives a tax saving of £252 per year (£1,260 × 20% tax rate). Over 4 years: £1,008 (assuming rates remain constant).
How it works: The non-taxpayer transfers 10% of their unused personal allowance (£1,260) to their partner. The receiving partner gets a tax code ending in ‘M’, while the transferring partner gets a code ending in ‘N’.
Annual subscriptions to approved professional bodies and trade unions qualify for tax relief. You can claim back 20-45% of the subscription cost depending on your tax rate.
Examples of qualifying subscriptions:
If you buy tools or equipment necessary for your job, you can claim tax relief on the cost. Unlike the flat rates above, this is based on your actual spending.
The amount you claim depends on what you’ve purchased and your tax rate. You’ll receive 20-45% of the cost back as a tax refund, depending on whether you’re a basic, higher, or additional rate taxpayer.
Common tax code problems that cause overpayments:
For 2024/25, the standard tax code is 1257L, which gives you the full personal allowance of £12,570. If your circumstances are straightforward (one job, no benefits, no other income), this is the code you should have.
How to check your tax code
If your tax code looks wrong, you can contact HMRC to review it. They may immediately correct it and issue a tax rebate for past overpayments. Our comprehensive tax code guide explains what each code means and how to challenge incorrect codes.

You can claim a tax rebate by:
Most claims take 20-30 minutes to complete and are processed within 8-12 weeks.
You can claim tax refunds for the previous 4 complete tax years. In 2024/25, you can claim back to 2020/21.
Important: Claims for 2020/21 must be submitted by 5th April 2025. After this deadline, you'll lose entitlement to that year's tax refund.
Tax rebate amounts vary based on your circumstances, expenses, and tax rate. Typical amounts include:
Your actual refund depends on how much tax you've overpaid. Use our tax rebate calculator for an estimate based on your circumstances.
You can claim tax back on work-related expenses that you've paid for yourself and that are necessary for your job:
Claims can be backdated for up to 4 years. Use our tax rebate calculator to estimate your refund.
HMRC typically processes tax rebate claims within 8-12 weeks. Simple claims submitted through your online Personal Tax Account are often processed faster, usually within 4-8 weeks.
Processing times can be longer during busy tax periods (January-April and after the tax year end in April). Once approved, bank transfers usually arrive within 3-5 working days. Cheque payments typically take 7-10 working days.
Self-employed individuals can claim tax relief on allowable business expenses through their Self Assessment tax return:
These expenses reduce your taxable profit. If you're both employed and self-employed, you can also claim PAYE tax rebates for employment expenses. Read our Self Assessment help guide or find an accountant for assistance.
Tax rebates are not counted as income when calculating benefit entitlement. However, once received, they become part of your savings.
If you claim means-tested benefits such as Universal Credit, savings above £6,000 may affect your payment amount. Contact Universal Credit for further clarification in your circumstances.
