Can an AI do my tax return in the UK?

Can an AI do my tax return in the UK? Partly. AI can sort transactions and draft figures, but only compatible software or HMRC's online service can send a return, and you stay responsible for it. HMRC's guidance of 28 January 2026 says AI should support, not replace, human judgement. No. A general chatbot cannot send anything to HMRC. Making Tax Digital updates must go through software listed on GOV.UK's software finder, and a chatbot also cannot see your bank records unless you paste them in. No. HMRC's guidance of 28 January 2026 says it does not endorse or approve any software developer or product, and that developers must not suggest they act on behalf of HMRC. You do, if HMRC finds the error was careless. HMRC says that if you ask someone else to do something for you, you must still do everything you reasonably can to prevent mistakes. A careless error can cost up to 30% of the extra tax due. Read the full answer, with every source, at rightotax.co.uk.
