Disclaimer

The short version: free, honest estimates — not advice, not HMRC, not a claims service.

Independence from HMRC

RefundCalculator is an independent private publisher. We are not affiliated with HM Revenue & Customs (HMRC), any UK government body, or the Student Loans Company, and nothing on this site should be read as an official statement of your tax position. Crown services referenced here remain the property of their owners.

About the estimates

  • Figures are produced from published tax rates applied to the inputs you provide, following the rules on our methodology page.
  • Provisional years (currently 2026-27) are labelled; rates may change when officially confirmed.
  • Your true liability or refund is determined only by HMRC based on its complete records.
  • Where an estimate and HMRC disagree, HMRC is right — use the official routes we link to check.

Not tax advice

Content is general information for UK residents. It does not consider your full circumstances and is not a recommendation to act. For decisions with real consequences — large refunds, residency, disputes — use HMRC's free helplines or a qualified professional (ATT/CTA, or a regulated accountant).

Availability and accuracy

We work to keep rates and routes current (update schedule in the editorial policy), but the site is provided "as is" without warranty. Found an error? The corrections page tells you how to report it — and shows our public log of fixes.
