How to Complete a VAT Return
HMRC Guidance / Practice
Overview
VAT Notice 700/12 is the primary reference guide for completing and submitting your VAT return. It guides you through the form box by box. You must complete a return for each tax period and send it to HMRC, paying any VAT due by the due date shown on the return.
How to Submit
Virtually all VAT-registered businesses are required to submit their returns via functional compatible software and pay electronically. All VAT-registered businesses are automatically signed up for Making Tax Digital (MTD) for VAT — you no longer need to sign up yourself. If you are exempt from digital record-keeping, you may file online or, if entitled, on paper.
Completing the Boxes (Form VAT100)
| Box | What to Enter |
|---|---|
| Box 1 | VAT due on your sales and outputs (output tax) |
| Box 2 | VAT due on acquisitions into Northern Ireland from EU member states |
| Box 3 | Total VAT due (calculated automatically as Box 1 + Box 2) |
| Box 4 | VAT reclaimed on business purchases (input tax), including acquisitions into Northern Ireland |
| Box 5 | Net VAT to pay or reclaim — deduct Box 4 from Box 3. If Box 3 > Box 4, you owe the difference; if Box 4 > Box 3, HMRC will repay the balance |
| Box 6 | Total value of all business sales (excluding VAT) |
| Box 7 | Total value of all business purchases (excluding VAT) |
| Box 8 | Total value of goods supplied to EU member states (excluding VAT) — must also be included in Box 6 |
| Box 9 | Total value of acquisitions into Northern Ireland from EU member states (excluding VAT) — must also be included in Box 7 |
Checking Your Figures Before Submission
Before submitting, HMRC advises you to check that:
- If all your outputs are standard-rated, Box 1 should be 20% of Box 6
- Box 5 should equal the difference between Box 3 and Box 4
- If Box 8 exceeds Box 6, or Box 9 exceeds Box 7, you may have transposed figures in error
- Once submitted via software or online, you cannot amend the return, so check carefully before clicking 'submit'
Special Situations
- Import VAT (Postponed VAT Accounting): If you use postponed VAT accounting (PVA), import VAT must still be included on your VAT return even where the net tax liability is nil.
- Reverse Charge: If you receive reverse charge supplies, enter the output tax in Box 1, reclaim input tax in Box 4, and include the value in Box 7 (but not Box 6 for domestic reverse charge).
- Correcting Errors: Errors on previous returns may be corrected via Boxes 1 and 4 of the current return, provided the net error is £10,000 or less, or between £10,000–£50,000 and does not exceed 1% of Box 6. Larger errors must be separately notified to HMRC.
