As of 12 August 2026, AI cannot do your VAT return.

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

What the alternative costsAn accountant handles a straightforward quarterly VAT return for £100–£300.

If this goes wrong: an error in a box total or a VAT treatment goes to HMRC under your registration, and corrections, interest and penalty exposure follow you into later quarters.

What to actually do

  1. Hand it to a person

    The route this page recommends

    Someone with a licence or accountable authority has to sign this before it counts.

    Where to find a person today

    • ICAEW Find a Chartered Accountant

      The ICAEW’s public directory of regulated chartered accountancy firms, searchable by location and specialism.

      VAT is where a chartered firm earns its fee: registration thresholds, schemes and edge-case treatments carry real liability, and the register is the vetted way to find someone who signs their name to them.

  2. Use a tool built for this

    Second choice

    Purpose-built software does the mechanical share of this.

    • Xero

      Making Tax Digital compatible accounting that computes the box totals from the bookkeeping and files them, which moves the work to keeping the books right, where it belongs.

    • ANNA Money

      Free

      Carries a free Making Tax Digital VAT filing route, which makes it the honest option when the figures already exist and the budget is nil.

  3. Do it yourself

    The distant third

    A chat interface gets you a draft, but you cannot verify it yourself. That is the catch.

    Prompt

    List the records I need to have ready before my UK VAT return is filed, and the deadlines and payment dates that apply to a standard quarterly period. Do not calculate any box figure and do not advise me on the VAT treatment of any transaction.

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

FAQ

Can ChatGPT do my VAT return?
No. The answer here is NO. A UK VAT return has to reach HMRC through Making Tax Digital compatible software, the registration and the penalties are yours, and a model states VAT treatments with a confidence the edge cases do not deserve.
Is it safe to use AI to work out my VAT?
Not for the figures you file. The failure is quiet: a mis-treated transaction flows into a box total, the return goes in under your registration, and the error surfaces as an HMRC correction with interest. You also cannot verify the answer without redoing the bookkeeping it came from.
What can AI safely do for my VAT return?
The preparation, not the filing. Ask it to list the records to gather, the deadlines for your quarter, and the transactions worth querying with your accountant. A record list is checkable; a VAT treatment is not.
How much does an accountant charge for a VAT return?
Commonly £100 to £300 for a straightforward quarterly return, more where the bookkeeping is behind. Accounting software computes the boxes from the books and files them, which moves the real work to keeping the books right.
