# How to do your VAT return with AI (UK, MTD-ready)

Use AI to keep records categorised all year, total the nine VAT boxes, and prep your quarterly return. AI gets the figures right and MTD-ready; it does not file to HMRC unless linked to compatible software, and a qualified accountant still owns submission.

## Steps
1. Keep every transaction categorised all year: A VAT return is only as clean as the records behind it. Have AI log and categorise sales and expenses as they land, capture the VAT on each, and flag anything that looks wrong, so you are never rebuilding a quarter from a shoebox of receipts. Under Making Tax Digital you must keep digital records, so this is not optional housekeeping - it is the requirement.
2. Track the nine VAT boxes as you go: A UK VAT return is nine boxes, from VAT charged on sales (box 1) to VAT reclaimed on purchases (box 4) and the net figure you owe or reclaim (box 5). Have AI keep a running total of each box from your categorised records, so the return is effectively written before the quarter ends.
3. Watch the registration threshold: If you are not yet VAT registered, have AI track your rolling 12-month taxable turnover against the £90,000 registration threshold and warn you as you approach it, so you register on time instead of discovering you were late.
4. Prep the quarterly return figures: At the end of each VAT period, have AI pull the nine box totals together, reconcile them against your bank, and flag anything unusual - a missing invoice, a miscategorised expense, VAT claimed where it should not be. You get a return that is ready to check, not a blank form.
5. Review before anything is submitted: Read the figures. AI preps and explains each box; you or your accountant confirm the judgement calls - what is reclaimable, which scheme applies, how to treat an edge case. Nothing goes to HMRC on autopilot.
6. Submit through MTD-compatible software: VAT returns must be filed to HMRC through Making Tax Digital compatible software over HMRC's API. AI hands you clean, reconciled figures to enter or push into that software. It does not file to HMRC itself unless it is connected to an MTD-compatible tool.

## FAQ
Q: How do I do a VAT return?
A: You add up the VAT you charged on sales and the VAT you paid on purchases for the period, complete the nine boxes of the return, then submit it to HMRC through Making Tax Digital compatible software - usually within one calendar month and 7 days of the period end. Most people keep digital records through the quarter so the figures are ready, then check and file. AI can do the record-keeping and the totting up; a qualified accountant should own the submission and any judgement calls.

Q: Can AI do my VAT return?
A: AI can prepare it - categorise your transactions, total the nine boxes, reconcile against your bank and hand you a return that is ready to check. What it should not do is file blind. Returns go to HMRC through MTD-compatible software, and unless the AI is connected to that software it does not submit for you. It is also not tax advice - a qualified accountant or HMRC owns the actual submission and any judgement on what is reclaimable.

Q: What are the 9 boxes on a VAT return?
A: Box 1 is VAT due on sales and other outputs. Box 2 is VAT due on acquisitions of goods (Northern Ireland from the EU). Box 3 is total VAT due, boxes 1 and 2 added. Box 4 is VAT reclaimed on purchases and other inputs. Box 5 is the net VAT to pay or reclaim, the difference between boxes 3 and 4. Box 6 is total sales excluding VAT. Box 7 is total purchases excluding VAT. Boxes 8 and 9 cover the value of goods dispatched to and acquired from the EU (Northern Ireland only). Always check current HMRC guidance for your situation.

Q: Do I need MTD software to file a VAT return?
A: Yes. Under Making Tax Digital for VAT, VAT-registered businesses must keep digital records and submit returns to HMRC through MTD-compatible software that connects to HMRC's API. You cannot key the figures straight into the old online form any more. AI can prepare and reconcile the numbers; the filing itself goes through compatible software.

Q: When is my VAT return due?
A: For standard quarterly VAT, the return and the payment are usually both due one calendar month and 7 days after the end of the VAT period. So a quarter ending 31 March is generally due by 7 May. Check the exact deadline in your HMRC VAT account, since some schemes and payment methods differ.
