Find accurate, official guidance on HMRC disputes, tax appeals and self assessment from GOV.UK and TaxAid.
If you believe HMRC has made an error, you can appeal a tax assessment within 30 days of the decision. You can ask for a review by HMRC or go straight to the Tax Tribunal. If HMRC has caused you loss through poor service, you can claim compensation.
You have the right to be treated fairly and have your data protected. HMRC's Charter sets out the standards you can expect. Complaints about HMRC service can be made to the Adjudicator's Office if HMRC's own complaints process fails.
Key areas covered: HMRC appeals, tax tribunal, wrong tax code, PAYE errors, self assessment, HMRC complaints. Checked against official sources.
The Charter sets out standards HMRC commits to — being responsive, treating you fairly, and getting things right — and while it isn't legally enforceable in the same way as a statutory right, referencing it in a complaint reinforces exactly what standard of service you're entitled to expect.
If HMRC's own complaints process doesn't resolve things, the Adjudicator's Office provides an independent review — and if you remain dissatisfied after that, your MP can refer the matter to the Parliamentary and Health Service Ombudsman for a final, independent assessment.
