Can AI work out my self-employed expenses?

Partly. It can sort transactions, add totals, identify duplicates and flag missing evidence, but it cannot safely decide every mixed-use, capital or unusual expense from a short description.

Can I use ChatGPT to claim business expenses?

You can use it to prepare a draft expense schedule, provided you check each item against your records and current GOV.UK guidance. It is not professional advice, and you remain responsible for what you claim to HMRC.

Can AI read my receipts and bank statements?

Yes, it can extract dates, suppliers and amounts from information you provide and organise them into a spreadsheet or schedule. Remove passwords and unnecessary personal information, and check every extracted figure against the original document.

Should I ask an accountant about a business expense?

Ask an accountant or tax adviser when an item is private or mixed-use, unusually large, related to property or vehicles, or difficult to classify. They can assess the facts and take professional responsibility where a wrong claim could have serious consequences.

PARTLY

As of 13 August 2026, AI can only partly claim self-employed business expenses.

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

If this goes wrong, you claim an expense HMRC does not accept or omit evidence and may need to correct the return, repay tax and deal with any resulting consequences.

A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

How to actually do it

Open your current GOV.UK guidance on allowable expenses for self-employed people and keep it available for checking.
Gather your business bank statements, card statements, receipts, invoices, mileage log, home-working records and details of any private use for the relevant tax year.
Remove account passwords and unnecessary personal information, then paste a dated transaction list or upload the records to the chatbot with the prompt above.
Answer the chatbot's clarification questions using your receipts, contracts, mileage log and business records, and ask it to recalculate the schedule from the corrected figures.
Compare every proposed category, private-use treatment and capital-versus-revenue flag with the relevant GOV.UK guidance and the original evidence, correcting any amount that does not match.
Put unclear or high-value items into a separate list and send that list, with the evidence and the GOV.UK pages you checked, to an accountant or tax adviser before including them in your Self Assessment return.

Prompt

I am a UK self-employed person preparing my business expense records for the tax year [tax year]. Help me prepare a checking schedule, not a final tax claim.

Use only the information I provide and current GOV.UK guidance that you can verify. If you cannot verify a rule or the relevant page is unclear, say that plainly and give me the GOV.UK page I should check. Do not invent figures, receipts, dates, categories or tax rules.

My business description is:
[business description]

My records are:
[paste a table or list of receipts, invoices, bank transactions, mileage and other evidence]

For each item, produce a table with:
- date
- supplier or description
- amount and currency
- business purpose
- proposed expense category
- whether it appears wholly business, partly private, or unclear
- evidence supplied
- whether it may need a capital-versus-revenue check
- the GOV.UK rule or source to check
- a cautious status: ready to check, needs evidence, or ask an accountant

Calculate totals only from the figures I provide. Keep private or mixed-use amounts separate and do not decide an apportionment unless I provide a defensible basis. Flag possible mileage or simplified-expenses issues without assuming that either method applies. List duplicates, missing evidence, VAT issues, personal spending and transactions that need clarification. End with a short list of questions I must answer before using the schedule. Do not tell me to claim an item merely because it appears in the records, and do not submit anything to HMRC.

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

What it gets wrong

AI cannot prove that an expense was wholly and exclusively for your business when the facts involve private or mixed use.
AI cannot replace missing receipts, reconstruct an unreliable mileage log or establish a defensible basis for apportioning a cost.
AI can misclassify capital purchases, finance costs, VAT and simplified expenses when the surrounding facts are incomplete.
AI cannot take responsibility for the figures or claims submitted to HMRC.
The final decision on an unusual or material item still needs your evidence and, in a serious case, an accountant or tax adviser.

What caps this at PARTLY: legal accountability, judgement under ambiguity and verification cost.
