Frequently Asked Questions
What is a P60?
A P60 is an end-of-year certificate your employer must give you by 31 May. It shows your total income and the tax deducted through PAYE during the tax year (6 April to 5 April).
Can I claim a refund using my P60?
Yes — if your P60 shows you've overpaid tax, you can claim a refund from HMRC. You can do this online via your Personal Tax Account at gov.uk, or by phone. HMRC also automatically issues refunds for many straightforward cases.
Why might I have overpaid tax?
Common reasons: emergency tax code used when starting a job, working part-year, having multiple jobs, not claiming all allowances (e.g., uniform allowance, professional subscriptions), or employer using wrong tax code.
How far back can I claim a tax refund?
You can claim overpaid income tax for up to 4 tax years prior to the current year. In 2025/26, you can claim back to 2021/22.
Is this calculator 100% accurate?
This is an estimate based on standard personal allowance and basic/higher rate tax only. It doesn't account for: Scottish income tax, blind person's allowance, marriage allowance transfers, or pension contributions. Always use HMRC's official figures.
Do I need to do Self Assessment?
Not if you're a standard employee. But if you have rental income, self-employment, or income over £100,000, you must file Self Assessment to reconcile your tax.
What if HMRC has my wrong tax code?
Contact HMRC to correct your tax code. A wrong code (e.g., emergency code 1257L W1/M1 or BR) causes overpayment. HMRC's helpline is 0300 200 3300.
When will HMRC send my refund?
HMRC processes most PAYE refunds within 5 working days of you claiming online. Cheques take longer. Automatic reconciliation refunds are typically issued after August for the previous tax year.
