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

How to actually do it
- Open the HMRC letter and gather every page, envelope or covering sheet, including any page that contains a deadline, amount, reference or reply address.
- Redact your National Insurance number, UTR, address, bank details, payment details and unique reference numbers, but leave the letter date, tax year, amounts and wording visible.
- Paste the complete redacted letter into a chatbot and use the prompt above, adding a note if any page or attachment is missing.
- Compare the chatbot's extracted purpose, deadline, amount and requested action word for word with the letter, correcting any transcription or interpretation error.
- Open GOV.UK and check the relevant HMRC guidance and the contact details printed on the letter rather than relying on links or phone numbers supplied only by the chatbot.
- Contact HMRC using the letter's official details for factual discrepancies, and ask a qualified tax adviser to check any disputed tax, penalty, appeal or payment decision before you respond.
Prompt
Explain the HMRC letter pasted below in plain British English. First identify the letter's purpose from its exact wording, then provide: 1) a short summary, 2) what HMRC says it has recorded or decided, 3) every action it asks me to take, 4) any deadline or amount stated, copied exactly rather than guessed, 5) what documents or information I may need, and 6) what I should ask HMRC if anything is unclear. Separate facts stated in the letter from your interpretation. Do not invent missing text, dates, amounts, tax years, deadlines or reasons. Do not decide whether I owe tax, whether a penalty is valid, or which reliefs apply. Flag anything that needs checking with HMRC or a qualified tax adviser, and link only to relevant GOV.UK pages where you can identify the page confidently. Tell me if the letter is incomplete or too unclear to interpret. I have removed personal identifiers such as my National Insurance number, UTR, address, bank details and reference numbers.

What it gets wrong
- AI cannot confirm that the letter is genuine or that its contact details are safe to use.
- AI cannot see HMRC's records or know whether the figures and facts in the letter are correct.
- AI cannot decide whether a penalty, tax charge or HMRC decision is legally correct for your circumstances.
- AI cannot take responsibility for your reply, appeal or payment if its explanation is wrong.
- AI cannot replace HMRC for account-specific corrections or a qualified tax adviser for a serious dispute.

FAQ
- Can ChatGPT explain a letter from HMRC?
- Yes, it can summarise the letter, translate HMRC wording into plain English and list the actions and deadlines it states. Check every extracted amount and deadline against the original, and remember this is not professional advice.
- Is it safe to upload my HMRC letter to AI?
- Redact your National Insurance number, UTR, address, bank details and unique reference numbers before uploading it. Do not treat the chatbot as a secure HMRC channel, and use the contact details on the letter or GOV.UK to confirm anything important.
- Can AI tell me if HMRC has made a mistake?
- It can identify apparent inconsistencies in the wording or arithmetic, but it cannot check HMRC's records or reliably determine whether the tax treatment is correct. For a disputed tax charge, penalty or appeal, ask HMRC or a qualified tax adviser.
- Can AI reply to HMRC for me?
- AI can draft a plain-English reply based on facts you provide, but you must check it and send it through the correct HMRC route yourself. A qualified tax adviser should check a reply about a serious tax dispute, penalty or appeal.
