As of 13 August 2026, AI can only partly complete UK form IHT205.

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 IHT205 and its guidance from GOV.UK, and check that the form or process applies to the date of death.
   2. Gather the death certificate, will and codicils, estate valuations, bank and investment statements, property information, debts, details of jointly owned assets, and records of gifts or transfers.
   3. Remove unnecessary personal identifiers, then upload the form and paste the factual information into a chatbot using the prompt above.
   4. Ask the chatbot to return the field-by-field draft, source for each answer, missing information and CHECK items rather than filling gaps.
   5. Compare every drafted name, date and figure against the original documents, and compare the eligibility and submission instructions against the current GOV.UK page.
   6. Ask a probate solicitor or other appropriate professional about any unresolved issue involving eligibility, gifts, trusts, joint ownership, valuations or tax, then complete and send the official form only through the current GOV.UK instructions.

   Prompt

   I need help preparing UK form IHT205 for an estate. Before drafting anything, check the current GOV.UK guidance for the date of death, [date of death], and confirm whether IHT205 is still the correct form or process. If it is not, stop and explain which official GOV.UK process I should check instead.
   
   Use only the information in the attached form, official GOV.UK guidance and the estate information below. Do not invent figures, assets, debts, gifts, dates, relationships or legal conclusions. Do not decide that an asset or gift can be omitted unless the official guidance clearly supports that treatment.
   
   Estate information:
   - Deceased: [name]
   - Date of death: [date]
   - Executors or administrators: [names]
   - Will and codicil details: [details]
   - Property and other assets with date-of-death values: [details]
   - Jointly owned assets: [details]
   - Debts and liabilities: [details]
   - Gifts or transfers before death: [details]
   - Trusts, foreign assets, life policies and pensions: [details]
   - Any other relevant information: [details]
   
   Return:
   1. A field-by-field table matching each answer to the current form, with the source document or GOV.UK section for each answer.
   2. A list of fields you cannot complete and the exact information needed.
   3. A list of issues that need checking with GOV.UK or a probate solicitor, especially anything involving eligibility, gifts, trusts, joint ownership, valuation or tax.
   4. A draft only. Mark every uncertain answer as CHECK rather than guessing.
   Do not present the draft as filed, submitted or professional advice.

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