VAT Return Boxes Explained: What Goes in Boxes 1 to 9 on the UK VAT Return

Filing your first VAT return is one of those tasks that looks simple until you open the form. Nine boxes. No instructions on the page itself. And every accountant you've ever met treats the boxes like a shared language everyone is supposed to already know.

This is the plain-English version I wish someone had given me.

What the VAT return actually is

The VAT return is how you tell HMRC three things: how much VAT you've charged on your sales, how much VAT you've paid on your purchases, and what that leaves you owing (or reclaiming). You file it online, usually once a quarter, and the figures you enter go into nine numbered boxes.

Two facts that make the whole thing easier:

1. Everything goes in as net figures in Box 6 and 7, but VAT figures in the others. The boxes where VAT is entered hold actual VAT amounts, not sales totals.
2. The return is about VAT, not profit. The profit you made is irrelevant here — HMRC only cares about the VAT moving in and out.

Boxes 1 to 5: the VAT amounts

Box 1 — VAT due on sales. Total VAT you've charged on sales in this period, including anything you sold in other EU countries (distance selling) plus VAT due on acquisitions from the EU. If you use the Flat Rate Scheme, this box holds your flat-rate percentage calculation instead.

Box 2 — VAT due on acquisitions from other EU member states. If you bought goods from another EU country, the VAT you owe on those acquisitions goes here.

Box 3 — Total VAT due (Box 1 + Box 2). HMRC wants this as one figure. Yes, you have to do the adding-up yourself.

Box 4 — VAT reclaimed on purchases. The VAT you've paid on business purchases and expenses this period — the input VAT you're allowed to claim back. Only claim what's genuinely allowable: block deductions (like cars in some cases, and anything that's personal) don't belong here.

Box 5 — Net VAT (Box 3 minus Box 4). This is the headline figure: what you owe HMRC. If Box 4 is bigger than Box 3, HMRC owes you — and you'll get a repayment instead of a bill.

Boxes 6 to 9: the totals HMRC uses for statistics and checks

Box 6 — Total value of sales excluding VAT. All your sales in the period, before VAT. This is the one people confuse with Box 1 — Box 1 is the VAT on those sales, Box 6 is the sales themselves.

Box 7 — Total value of purchases excluding VAT. Everything you bought for the business, before VAT.

Box 8 — Total value of supplies of goods to other EU member states. Post-Brexit this is narrower than it used to be (goods moved to Northern Ireland have their own rules), but if you supply goods to EU customers this is where they go.

Box 9 — Total value of acquisitions of goods from other EU member states. The counterpart of Box 8: goods you've brought in from the EU.

The three mistakes I see most often

Entering figures with VAT included in Box 6 and 7. These two boxes are always ex-VAT. Getting this wrong inflates your reported turnover figures and can trigger HMRC queries.

Claiming VAT on things that aren't reclaimable. Client entertainment, some car purchases, and anything used for non-business purposes sit outside what you can reclaim. When in doubt, don't claim — a wrongly claimed £500 of input VAT costs far more in interest and penalties than it ever saved.

Missing the deadline. The return is due one month and seven days after the end of the VAT period, and paying late racks up penalties fast. Set a reminder the day the period closes, not the day before it's due.

A simple workflow that works

1. On the first day after the period ends, reconcile your accounting software to the quarter.
2. Work through the boxes in order — 1 through 5, then 6 through 9. The return is designed to be sequential.
3. Sanity-check: Box 5 should roughly equal the VAT on your Box 6 sales minus the VAT on your Box 7 purchases. If it's wildly different, a figure has been mis-entered.
4. Submit, then pay or wait for your repayment.

The UK VAT return form only makes sense once someone explains what each box is for. For a deeper walkthrough of the return itself — including worked examples of Box 1 to Box 5 on real figures — this plain-English breakdown of the VAT return boxes walks through each box with the numbers shown. Once you understand the boxes, the filing takes minutes.
