Why you might be owed a tax rebate
The PAYE (Pay As You Earn) system usually works well, but it's not perfect. It assumes your income will be exactly the same every month. If your circumstances change, the system can charge you the wrong amount of tax.
You're most likely to be owed a tax refund if:
- You were placed on an emergency tax code (like W1/M1) when starting a new job without a P45.
- You only worked for part of the tax year (meaning your tax-free personal allowance wasn't fully used).
- You had multiple jobs at the same time, leading to your allowances being split incorrectly.
- You received a bonus that pushed you into a higher tax bracket for one month, but your annual salary doesn't reach that bracket.
How to claim your tax refund
If our calculator shows you've overpaid, the good news is that getting your money back is relatively straightforward.
In many cases, HMRC will automatically send you a P800 tax calculation letter between June and October. This letter will tell you how to claim your refund online, or they may just send you a cheque.
If you don't want to wait, you can log into your Personal Tax Account on the Government website. If a refund is due, there will often be a button to claim it instantly via bank transfer.
