As of 13 August 2026, AI can only partly check whether your savings interest is taxable.
Most people should hand this to a purpose-built tool.

What the alternative costsAn alternative is DocuClipper, which converts bank and card statements into clean spreadsheets automatically.
If this goes wrong, you may omit taxable interest or report an incorrect amount and have to correct the position with HMRC.

How to actually do it
- Open GOV.UK guidance on tax on savings interest and note the tax year you are checking.
- Gather every bank or building-society statement for that tax year, including statements for cash ISAs, fixed-term accounts, easy-access accounts and joint accounts.
- Copy the interest credited, tax deducted, account type, account holder names and payment dates into one list, keeping the original statements available.
- Gather your other taxable income for the same tax year, such as employment, pension, property or self-employment income, without estimating missing amounts.
- Paste the prompt and the figures into a chatbot, then ask it to keep separate totals for each account and to identify every missing fact.
- Compare the chatbot's explanation and GOV.UK links with the account statements and your income records, correcting any extracted figure that does not match.
- If the result involves overseas interest, trusts, unclear joint ownership, a repayment claim or an HMRC dispute, send the records and the unanswered points to HMRC or a UK tax adviser before reporting the figure.
Prompt
Help me check whether my UK savings interest is taxable for the tax year [TAX YEAR]. This is not professional advice. Use only the information I provide and current GOV.UK guidance, and link to the relevant GOV.UK pages. Do not guess missing figures or assume which tax allowances apply. First list the information needed, including my taxable income apart from savings interest, interest from each account, any tax deducted, whether each account is an ISA, whether any account is joint, and whether any interest came from overseas. Then put the figures into a clear table, separate interest that is normally tax-free from interest that may need to be considered, explain which parts depend on my wider tax position, and show any arithmetic. Mark each conclusion as confirmed, likely, or needing HMRC or an accountant to check. If the information is incomplete or the case involves overseas income, trusts, a jointly held account, a tax repayment claim, or a dispute with HMRC, stop short of a conclusion and give me the exact information or professional help needed.

What it gets wrong
- AI cannot know whether your account details and wider income are complete unless you provide and check them.
- AI cannot reliably resolve unusual ownership, overseas interest, trusts or conflicting bank records without specialist judgement.
- AI cannot guarantee that its explanation reflects the relevant tax-year rules or HMRC's treatment of your individual case.
- The chatbot does not take responsibility for an incorrect figure or report made to HMRC.

FAQ
- Can ChatGPT tell me if my savings interest is taxable?
- It can organise your figures and explain the likely treatment using GOV.UK guidance, but it cannot take responsibility for the conclusion. You must check the figures, tax year and account details, and ask HMRC or an accountant about an unusual case.
- Do I pay tax on savings interest in the UK?
- Some savings interest may be covered by tax-free rules, while other interest may count towards your taxable income. The answer depends on the account type and your wider income, so check the current GOV.UK guidance for the relevant tax year.
- Is interest from an ISA taxable?
- Interest from an ISA is generally treated differently from interest from an ordinary savings account. Confirm the account is actually an ISA and check the relevant GOV.UK guidance before excluding it from your figures.
- What if I do not know how much interest I received?
- Ask the bank or building society for an annual interest statement or use the interest entries in your statements. Do not let AI estimate the amount, because you remain responsible for the figure reported to HMRC.
