Tax Rebate FAQ
Answers to the most frequently asked questions about claiming tax refunds from HMRC.
A tax rebate (or tax refund) occurs when you have overpaid Income Tax to HMRC. This can happen due to being placed on an emergency tax code, having allowable work-related expenses (like uniforms or working from home), or qualifying for Marriage Allowance.
HMRC allows a flat rate tax relief of £6 per week (£312 per year) if you are required to work from home by your employer. The actual rebate you receive depends on your marginal tax rate: £62.40 per year for basic rate (20%) taxpayers, and £124.80 for higher rate (40%) taxpayers.
You can generally claim tax relief for overpayments and allowable expenses going back up to 4 previous tax years. For example, in the current 2024/2025 tax year, you can claim for 2023/2024, 2022/2023, 2021/2022, and 2020/2021.
Once you submit a claim (via a P800 calculation, a simple online claim, or a self-assessment tax return), HMRC typically processes tax rebates within 4 to 6 weeks. If you are owed money, it will be paid directly into your bank account or via a cheque.
