As of 13 August 2026, AI can only partly report freelance income to HMRC.

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, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open the current Self Assessment guidance and online service on GOV.UK, and note the tax year and the sections HMRC says apply to your freelance income.
   2. Gather your invoices, payment platform records, bank statements, receipts and records of business expenses for that tax year, separating personal transactions from freelance transactions.
   3. Convert statements into a spreadsheet if useful, then remove unnecessary personal details and paste the relevant rows, invoice totals and expense records into a chatbot with the prompt above.
   4. Ask the chatbot to total income and expenses by category, show its arithmetic, and list every missing or uncertain item instead of filling gaps.
   5. Compare each income total with your invoices and bank or payment records, compare each expense with its receipt, and check any proposed deduction against the current GOV.UK guidance.
   6. Enter only the confirmed figures into the HMRC online return yourself, or send the organised records and unresolved questions to an accountant or tax adviser before submitting.

   Prompt

   Help me prepare, but not submit, a UK Self Assessment draft for freelance income for [tax year]. Use only the records and facts I provide. First list the documents and figures needed, then organise my freelance income and expenses into a table, show the arithmetic for each total, and identify missing, duplicated or unclear items. Do not invent figures, tax rules, deadlines, expenses, reliefs or allowable deductions. Do not decide whether an expense is tax-deductible unless you can point me to the relevant current GOV.UK guidance, and label that point as requiring my confirmation. Keep personal and freelance transactions separate. Produce a final checklist of figures to reconcile against my invoices, bank statements and receipts, and map the confirmed figures to the relevant Self Assessment sections only where the mapping is clear. Mark every uncertainty as CHECK rather than guessing. I will paste anonymised records below.
