As of 13 August 2026, AI can only partly report rental income on your tax return.

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 your HMRC Self Assessment records and note the tax year, property ownership share and whether the property was let for all or only part of the year.
   2. Gather rent statements, bank entries, letting-agent statements, invoices, receipts and loan-interest statements, then remove unrelated personal transactions.
   3. Create one list or spreadsheet with the date, description, amount and supporting evidence for every rent receipt and property cost, keeping income and costs in separate sections.
   4. Paste the property facts and the complete lists into the prompt, replacing each bracketed slot without including unnecessary account numbers or other private data.
   5. Ask the chatbot to reconcile the totals and flag uncertain, personal, capital or missing items before it produces a draft summary.
   6. Compare every drafted amount with the original statements and receipts, and check each flagged tax-treatment question against the current property-income guidance on GOV.UK.
   7. Enter only figures and claims you have checked into the relevant HMRC return, and ask a qualified tax adviser to check the return if ownership, loans, improvements, overseas property or unusual arrangements are involved.

   Prompt

   I need help preparing the rental income section of my UK Self Assessment tax return for [tax year]. Do not file anything or present your answer as professional advice. Use only the information I provide and do not invent, estimate or fill gaps.
   
   My property arrangement is: [brief description, including whether it is jointly owned, furnished, let for part of the year, or used personally].
   
   Rental income received:
   [paste a dated list or spreadsheet of rent received, deposits retained and other property-related receipts]
   
   Expenses paid:
   [paste a dated list with supplier, description, amount and whether it was for the property]
   
   Other relevant facts:
   [paste loan interest, periods empty, repairs, improvements, letting-agent fees, insurance, council tax, utilities, ownership shares and any other facts]
   
   Please do the following:
   1. Reconcile the income and expense totals from my records and show the arithmetic.
   2. Put each item into a clear table with: date, description, amount, proposed category and evidence needed.
   3. Separate items that appear to be ordinary income or expenses from items whose tax treatment is uncertain, capital, personal or dependent on a special property rule.
   4. Do not decide that an uncertain item is allowable. Flag it and state the exact fact or current GOV.UK guidance I need to check.
   5. List missing records and contradictions, and ask focused questions before calculating anything affected by them.
   6. Produce a final draft summary for me to compare with the HMRC return, clearly labelling every figure as either supplied by me, calculated from supplied figures or still unverified.
   7. Link to the relevant current GOV.UK pages where possible. If you cannot verify the current rule for [tax year], say so plainly.
