Can AI do my VAT return?
Short answer
Partly. AI in bookkeeping apps can read receipts, suggest VAT codes and match bank transactions, which does much of the work. But since April 2022 all VAT-registered businesses must keep digital records and file through Making Tax Digital compatible software, so a chatbot can't file it. You're still responsible for checking the figures.
Where AI helps
| Task | AI help |
|---|---|
| Capturing receipts and bills | Reads supplier, date, amount and VAT |
| Coding transactions | Suggests categories and VAT rates |
| Spotting errors | Flags duplicates and missing receipts |
| Explaining rules | A chatbot can explain flat rate or reverse charge in general terms |
| Filing | MTD-compatible software only |
What to check before you submit
- Each purchase has a valid VAT invoice if you reclaim VAT.
- Zero-rated, exempt and outside-scope items are coded correctly.
- Reverse charge items, such as overseas software and construction services under the domestic reverse charge, are handled properly.
- Totals match your bank.

Can a VAT return be amended?
Yes. If the net error is £10,000 or less, or up to £50,000 and no more than 1% of your box 6 figure, correct it on your next return. Larger errors, or deliberate ones, must be reported to HMRC separately (checked 18 October 2026).
