As of 13 August 2026, AI can only partly claim a tax refund from HMRC.
This still needs a person who signs their name to it.

How to actually do it
- Open the relevant tax refund guidance or form on GOV.UK and save the page URL or copy the relevant instructions.
- Gather the documents connected with the refund, such as payslips, P60s, receipts, expense records and HMRC letters, and redact passwords, login codes, National Insurance numbers and unnecessary personal details.
- Paste the GOV.UK instructions, your reason for the refund and a list of the documents and figures into the prompt.
- Ask the chatbot to produce the evidence table, missing-information list and draft answers without estimating or filling gaps.
- Compare every drafted figure and statement with the original documents, then compare the proposed route and required evidence with the current GOV.UK page.
- Enter the checked information yourself in the HMRC form or account, attach only the requested evidence and save the confirmation.
Prompt
I am in the UK and want to claim a tax refund from HMRC. Help me prepare the claim, but do not submit it and do not ask for passwords, login codes, my National Insurance number or other unnecessary identifying information. My situation: - Tax year or years: [insert] - Reason I think I am due a refund: [insert] - Employment, pension or other relevant income: [insert] - Expenses or deductions involved: [insert] - HMRC messages or letters: [paste redacted text] - Documents and figures I have: [list or paste redacted information] - HMRC GOV.UK page or form I intend to use: [paste URL or text] Use only the information I provide and the GOV.UK material I provide. Do not invent figures, dates, eligibility, expenses, reliefs or deadlines. First, explain what type of refund claim this appears to be and list the evidence needed. Then create a table matching each figure in the proposed claim to its source document, flagging anything missing, ambiguous or inconsistent. Draft the answers or wording I may need to enter, marking every point I must confirm myself. State clearly what you cannot determine. Finish with a short checklist for comparing the draft with my records and submitting it through the correct HMRC route. This is not professional advice.

What it gets wrong
- AI cannot access your HMRC account, see your complete tax record or know which refund route HMRC has assigned to your case.
- AI cannot establish entitlement where the claim depends on detailed facts, changing tax rules or an unclear expense.
- AI cannot take responsibility for the claim or deal with HMRC if the information is challenged.
- Uploading unredacted payslips, letters or bank records exposes private financial information to the chatbot.
- AI cannot submit the claim in your name or confirm that HMRC has accepted the refund.

FAQ
- Can ChatGPT claim a tax refund from HMRC for me?
- No. It can organise your evidence and draft answers, but you must use the correct HMRC route, check the figures and submit the claim yourself. The liability stays with you.
- Can AI tell me if I am due a tax refund?
- It can help compare your documents with HMRC guidance, but it cannot reliably decide a complicated claim from incomplete facts. Check the relevant GOV.UK guidance and use a qualified tax adviser or accountant for a serious or disputed case.
- What documents do I need to claim a tax refund from HMRC?
- That depends on why you think you overpaid tax. AI can turn your circumstances and the relevant GOV.UK instructions into a checklist, but you must confirm the list against the current HMRC page before sending anything.
- Is it safe to use AI for an HMRC tax refund claim?
- Use it for organising and drafting, not as the final authority, and redact unnecessary personal and financial details. This is not professional advice, and a serious or unclear case needs a qualified tax adviser or accountant.
