PAYE refund basics
How to Estimate a UK Tax Refund from Your P60 or Payslip
A PAYE refund can arise when Income Tax deducted during the year is higher than the Income Tax due after HMRC considers your annual income, allowances and eligible reliefs.

Countries covered by this UK guide
England, Scotland, Wales and Northern Ireland
These guides cover taxpayers across the United Kingdom. Scotland has its own Income Tax bands for earnings, pensions and most other non-savings income. England, Wales and Northern Ireland currently use the main UK Income Tax bands. National Insurance is calculated under UK-wide rules, while the correct student-loan plan depends on your loan history.
The refund calculation in plain English
PAYE spreads an estimate of Income Tax across your pay periods. The final position compares tax already deducted with tax due on the whole year’s taxable income.
A refund is therefore usually a repayment of your own overpaid tax, not an additional benefit or a percentage of your expenses.
- ✓ Add taxable income from all jobs and pensions
- ✓ Subtract eligible deductions and apply the Personal Allowance
- ✓ Calculate tax using the bands that apply
- ✓ Compare the result with PAYE Income Tax deducted
Example: If £9,200 was deducted but estimated Income Tax is £8,450, the indicative refund is £750.

Which figures to collect
A P60 shows pay and Income Tax deducted for a job held at the end of the tax year. HMRC says you receive a separate P60 for each job you still hold on 5 April. A P45 covers a job that ended, while final payslips can help reconcile the year.
For multiple jobs, total the annual taxable pay and PAYE Income Tax deducted from the records that cover the year, without counting the same previous-employment totals twice. Keep National Insurance and student-loan deductions separate; neither belongs in the PAYE Income Tax already deducted field.
- ✓ P60 from each job held on 5 April
- ✓ P45 for employment that ended
- ✓ Final payslips used to reconcile annual totals
- ✓ Pension contribution records
- ✓ Receipts for qualifying employment expenses
- ✓ Details of other taxable income

Use the ToolsFA calculator step by step
Select where you pay Income Tax so the calculator applies the Scottish bands or the main bands used for England, Wales and Northern Ireland. Enter annual taxable employment pay, net self-employment profit and supported other non-savings income separately. Then enter PAYE Income Tax already deducted from your records.
Enter a gross relief-at-source pension contribution only after identifying the arrangement, and do not re-enter a net-pay contribution already reflected in taxable pay. Add only eligible Income Tax deductions. The calculator estimates Income Tax and an indicative PAYE balance; it does not reproduce a tax code, benefits in kind, savings or dividend tax, Marriage Allowance, High Income Child Benefit Charge, Capital Gains Tax, every pension method or each payroll period.
- ✓ Choose the applicable UK nation
- ✓ Enter annual taxable pay from consistent records
- ✓ Add PAYE Income Tax deducted without National Insurance or loan deductions
- ✓ Enter supported pension and other deductions once
- ✓ Calculate and compare the indicative balance with HMRC's records

Worked example using the calculator fields
Assume an England scenario with £52,000 employment income, £600 of supported other non-savings income, no self-employment profit, a £2,600 gross pension contribution, £350 of other eligible deductions and £9,200 of PAYE Income Tax already deducted.
Under the calculator's simplified annual method, total income is £52,600. After £2,950 of entered deductions and the £12,570 Personal Allowance, taxable income is £37,080. At the 20% main rate used for this amount, estimated Income Tax is £7,416, producing an indicative £1,784 refund against £9,200 of PAYE tax deducted.
This is a reproducible ToolsFA example, not an HMRC decision. It assumes the entered pension and deductions are eligible and excludes savings, dividends, benefits, tax-code adjustments and other unsupported items.
Example: £9,200 PAYE deducted − £7,416 estimated Income Tax = £1,784 indicative refund under the stated assumptions.
Why your result can differ from HMRC
A calculator cannot infer an emergency tax code, benefits in kind, savings, dividends, Marriage Allowance, multiple payroll calculations or an earlier-year adjustment embedded in your tax code. A P800 or Self Assessment calculation can therefore differ even when the arithmetic in the estimate is correct.
Use the estimate to identify a question, then check HMRC’s current-year or previous-year service and the official claim route that matches the reason for overpayment. ToolsFA does not file a claim. HMRC may correct a current-year overpayment through an updated tax code and payroll once it has complete income details.
Frequently asked questions
Does a P60 show National Insurance separately?
Yes. Use the Income Tax deducted figure for the refund estimate, not the National Insurance amount.
What if I have more than one P60?
Reconcile annual taxable pay and PAYE Income Tax deducted across all jobs. Use each tax-year amount once and avoid duplicating previous-employment figures already carried into another record.
Can an emergency tax code cause an overpayment?
It can, particularly when HMRC or payroll did not yet have complete information. Check the tax code and HMRC record rather than assuming every difference is a claimable refund.
Does the calculator include savings, dividends or benefits in kind?
No. It models supported non-savings income and selected deductions. Those items and tax-code adjustments require a fuller HMRC calculation.
Is the calculator a refund claim?
No. It provides an estimate; any claim or correction must use the appropriate HMRC process.
