PARTLY

As of 13 August 2026, AI can only partly pay your Self Assessment tax bill.

This still needs a person who signs their name to it.

If this goes wrong: you send the wrong amount or reference, and the payment may not settle the bill on time.

What to actually do

  1. Hand it to a person

    The route this page recommends

    A person who owns the outcome does this end to end, worth it when the failure is dear.

  2. Use a tool built for this

    Second choice

  3. Do it yourself

    The distant third

    A chat interface, no skill needed, and roughly 15 minutes until you can act on the result.

    How to actually do it

    1. Open your HMRC online account through GOV.UK and open the current Self Assessment bill.
    2. Gather the amount due, payment deadline, payment reference and the HMRC payment route shown for your bill, without copying passwords or full bank details.
    3. Paste the redacted bill details into the prompt and ask the chatbot to produce a payment checklist, not to claim that it has paid anything.
    4. Compare every amount, reference and destination in the chatbot's checklist with the live HMRC account before opening your banking app.
    5. Open your bank's payment screen, enter the details yourself, and compare the recipient, amount and reference with HMRC immediately before confirming.
    6. Save the bank confirmation and return to your HMRC account to check that the payment has been recorded when the account shows its updated status.

    Prompt

    Help me pay my UK Self Assessment tax bill without making the payment yourself. Use only the information I provide and do not invent payment details, deadlines, penalties or HMRC rules. Tell me which details I need to check in my HMRC account before paying, including the amount, due date, payment reference and destination. Give me a short checklist for checking the payment in my bank before I confirm it. Do not ask for or repeat passwords, full bank details, security codes or other private login information. If anything is missing or unclear, tell me to check GOV.UK or contact HMRC rather than guessing. State plainly that this is not professional advice and that I remain responsible for making the payment correctly. My bill details are: [paste only the relevant, redacted details here].

    Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong

  • AI cannot access your HMRC account or see whether the bill is still outstanding.
  • AI cannot make the bank payment or confirm that HMRC has received it.
  • AI cannot accept responsibility if the amount, reference or destination is wrong.
  • AI cannot resolve an unusual payment problem, disputed balance or penalty; HMRC or a tax adviser must handle that.
  • AI cannot safely supply missing account details or current rules without a source you can check.

What caps this at PARTLY: legal accountability, verification cost and stakes of error.

FAQ

Can ChatGPT pay my Self Assessment tax bill?
No. A chatbot can help you organise the details and explain the steps, but you must make the payment through HMRC and your bank yourself. Check the amount, reference and destination against your live HMRC account.
Is it safe to use AI to pay HMRC?
It is safer to use AI only as a checklist, not as the source of payment details. Do not share passwords or security codes, and do not rely on a chatbot for an unverified account number, reference or deadline.
What details do I need to pay my Self Assessment bill?
Use the current bill in your HMRC account to find the amount due, the deadline, the payment reference and the payment route. The exact details can vary, so check GOV.UK or HMRC rather than accepting a chatbot's guess.
Can AI tell me why my HMRC payment has not gone through?
It can help you list what to check, such as the payment reference, amount and bank confirmation. It cannot inspect HMRC's records or resolve a disputed balance, so a serious or unresolved case needs HMRC or a tax adviser; this is not professional advice.
