An eligible expense claim may use P87 or an HMRC tax-code correction; confirm the route for your circumstances. Check whether you already file Self Assessment and follow the relevant HMRC instructions; the calculator cannot determine your filing obligation.
Check HMRC’s P87 guidanceEstimate a possible current-year PAYE overpayment after selected, qualifying employment expenses. Historic working-from-home and additional relief-at-source pension scenarios are displayed separately and are not added to the current-year estimate.
This is a full-tax-year illustration, not an in-year payslip or repayment calculation. For 2026/27, use annual PAYE Income Tax already paid or a clearly identified full-year estimate; the 2026/27 P60 is issued after the tax year ends. The refund estimate is capped at the tax paid or forecast that you enter.
The model does not inspect your P60, tax code, HMRC record, supporting evidence, approved-subscription list, occupation-specific uniform rate, other income, prior-year PAYE or filing obligations. Scotland applies Scottish bands to non-savings employment income; England, Wales and Northern Ireland use rUK bands. Historic WFH and additional relief-at-source pension figures are separate estimates and are not included in the current-year refund. Check eligibility and the claim route with HMRC; Marriage Allowance is assessed separately.
Use these GOV.UK and HMRC sources to verify eligibility, evidence, tax-year limits and the route for any refund. This calculator is an estimate, not an HMRC decision.
