How the UK tax refund estimate works

For 6 April 2026 to 5 April 2027, the calculator combines your employment, self-employment and other non-savings income. It subtracts entered pension contributions and eligible deductions, applies the Personal Allowance and calculates progressive Income Tax. The standard Personal Allowance is £12,570 and reduces by £1 for every £2 of adjusted net income above £100,000.

England, Wales and Northern Ireland use the main 20%, 40% and 45% rates. Scotland uses separate starter, basic, intermediate, higher, advanced and top bands. The calculator also estimates employee Class 1 and self-employed Class 4 National Insurance.

Worked UK tax examples

Example: possible PAYE refund

If your P60 shows £9,200 of PAYE tax but estimated Income Tax is £8,450, the indicative refund is £750, assuming no Class 4 amount is due.

Example: possible amount owing

If £6,000 was deducted but Income Tax and Class 4 total £7,100, the estimated balance is £1,100 owing.

Example: pension contribution

If you paid £800 and a relief-at-source provider added £200, enter the £1,000 gross contribution.

Example: Plan 2 loan

At £35,000 of repayment income, the simplified estimate is 9% of the amount over the £29,385 threshold.

Important limitations

This is an educational estimate, not a Self Assessment return or HMRC calculation. It does not calculate savings and dividend bands, capital gains, High Income Child Benefit Charge, Marriage Allowance, benefits in kind, tax-code adjustments, multiple payroll periods or every pension-relief method.
