How to Claim Your Tax Rebate

1

Calculate Your Entitlement

Use our calculator above to work out how much you could claim back. Make a note of all claimable expenses.

2

Gather Evidence (If Needed)

For flat rate expenses, no receipts are needed. For actual costs or amounts over the flat rate, keep records of what you spent.

3

Choose Your Claim Method

Under £2,500: Use form P87 online or through your HMRC Personal Tax Account. Over £2,500: Complete a Self Assessment tax return.

4

Submit Your Claim

Log into your HMRC Personal Tax Account and submit your claim online. It's free and typically the fastest method.

5

Receive Your Rebate

HMRC processes claims within 2-12 weeks. Rebates are paid by bank transfer or cheque, or your tax code may be adjusted.

Avoid Tax Rebate Companies You can claim tax rebates directly from HMRC for free. Companies that offer to claim for you typically charge 30-50% of your rebate as a fee. Save your money and claim yourself!

Working From Home Tax Relief

If your employer requires you to work from home regularly, you may be able to claim tax relief on household costs.

Flat Rate Method

  • Claim £6 per week (£312/year) without receipts
  • No need to calculate actual costs
  • Basic rate (20%): £62.40/year rebate
  • Higher rate (40%): £124.80/year rebate
  • Claim for years you worked from home

Actual Costs Method

  • Calculate proportion of bills used for work
  • Include: heating, electricity, internet
  • Potentially higher rebate than flat rate
  • Requires keeping detailed records
  • Good if you have high energy costs

Who Qualifies?

  • Must be required by employer to work from home
  • Cannot claim if you choose to WFH
  • Hybrid workers can claim for WFH days
  • Self-employed use different rules
  • COVID-19 claimants can continue if applicable

Professional Subscriptions Tax Relief

If you pay professional body membership fees relevant to your job, you can claim tax relief - but only if the organisation is on HMRC's approved list.

Profession Example Bodies Typical Fee
Accountants ACCA, CIMA, ICAEW £200-400
Engineers IMechE, IET, ICE £150-300
Nurses/Healthcare NMC, GMC, HCPC £100-400
Teachers NEU, NASUWT £150-200
Solicitors Law Society, SRA £300-500
Check the List HMRC maintains a list of approved professional bodies. Check List 3 on GOV.UK to see if your subscription qualifies.

Frequently Asked Questions

How do I check if I'm owed a tax rebate?
You may be owed a tax rebate if: you've paid too much tax through PAYE (wrong tax code), you can claim work expenses like uniform cleaning or tools, you've worked from home, you've stopped working mid-year, or you've been on an emergency tax code. Use our calculator above to estimate your potential refund, then claim via your HMRC Personal Tax Account.
How far back can I claim a tax rebate?
You can claim tax rebates for the current tax year plus the previous 4 complete tax years. For example, during 2025/26 you can claim back to 2020/21. After 5 April each year, the oldest year falls off - so don't delay your claim or you'll lose money!
Do I need receipts to claim tax relief?
For flat rate expenses (uniform allowance, WFH £6/week), you don't need receipts - HMRC accepts these claims without evidence. For actual expenses or claims above the flat rate, you should keep records for at least 22 months after the tax year ends, as HMRC may request evidence.
How long does HMRC take to process a rebate?
HMRC typically processes tax rebate claims within 8-12 weeks. If you claim online via your Personal Tax Account, it's often faster (2-4 weeks). Bank transfers are quicker than cheques. You'll receive a P800 letter confirming any refund due.
What is form P87?
Form P87 is used to claim tax relief on employment expenses when the total is under £2,500. You can submit it online through your HMRC Personal Tax Account or by post. For claims over £2,500, you need to file a Self Assessment tax return instead. P87 covers uniforms, tools, professional subscriptions, and working from home relief.
Can I claim if my employer provides a uniform?
Yes, even if your employer provides your uniform, you can claim for the cost of washing, maintaining, and repairing it - this is what the flat rate allowance covers. You cannot claim if your employer provides a laundering service or pays you a laundry allowance that covers your costs.
What's the difference between a tax rebate and tax code adjustment?
A tax rebate is a lump-sum refund of tax you've already overpaid. A tax code adjustment changes your future tax code so you pay less tax going forward. For ongoing expenses (like annual professional subscriptions), HMRC often adjusts your tax code. For backdated claims, you'll receive a rebate cheque or bank transfer.
Should I use a tax rebate company?
No - we strongly recommend claiming directly from HMRC for free. Tax rebate companies typically charge 30-50% of your rebate as their fee, plus VAT. The claim process is straightforward through your Personal Tax Account or form P87. Why pay someone £150 to claim a £300 rebate when you can keep it all yourself?
