Understanding the nine boxes on a UK VAT return

Every UK VAT return, submitted through Making Tax Digital software, comes down to nine numbered boxes. This tool reads a bank statement, estimates the VAT element of each transaction and arranges the totals into those boxes so you can see roughly where a return would land. It is an estimating aid: a bank statement alone cannot tell you everything a VAT account records, so treat the output as a cross-check, never as figures to file.

What each box means

BoxWhat goes in it
1VAT due in the period on sales and other outputs
2VAT due on acquisitions of goods made in Northern Ireland from EU member states
3Total VAT due: box 1 plus box 2
4VAT reclaimed in the period on purchases and other inputs
5Net VAT to pay to HMRC, or to reclaim: box 3 minus box 4
6Total value of sales and other outputs, excluding VAT
7Total value of purchases and other inputs, excluding VAT
8Total value of dispatches of goods from Northern Ireland to EU member states, excluding VAT
9Total value of acquisitions of goods into Northern Ireland from EU member states, excluding VAT

Since Brexit, boxes 2, 8 and 9 apply only to goods moving between Northern Ireland and the EU under the Northern Ireland Protocol. For a business trading only in Great Britain they are normally zero. A negative box 5 means HMRC owes you a repayment; this tool shows that with a minus sign.

The rates the tool looks for

Zero-rated and exempt look identical on a bank statement but behave very differently on a return: zero-rated sales still count as taxable supplies and preserve your right to reclaim input VAT, while exempt sales do not. A statement rarely carries enough information to make that call reliably, which is another reason to verify against invoices. For category-by-category examples and the full zero-rated versus exempt distinction, see our UK VAT rates guide.

Registration thresholds

VAT registration becomes compulsory once taxable turnover for the past 12 months goes over £90,000 (or is expected to within the next 30 days); deregistration is possible below £88,000. Every VAT-registered business, whatever its size, has had to keep digital records and file through MTD-compatible software since April 2022.

A worked example

A consultancy invoices £12,000 plus VAT in a quarter and buys £4,000 (net) of standard-rated goods and services:

A note on the Flat Rate Scheme

The tool labels transactions with a scheme column, but its box arithmetic follows standard VAT accounting: output VAT minus reclaimed input VAT. Flat Rate Scheme returns work on a different basis entirely (a fixed sector percentage applied to gross turnover, with input VAT generally not reclaimable), so Flat Rate users should not rely on this tool's box figures. The scheme's rules and thresholds are covered in our VAT rates guide.

Frequently asked questions

Can I file these figures with HMRC?
No. The figures are AI-generated estimates from a single bank statement. A real return must come from your VAT account and invoices, filed through MTD-compatible software.
Why does the tool assume 20% on my purchases?
Without an invoice, the safest general assumption for business purchases is the standard rate. Purchases that are actually zero-rated, reduced-rated, exempt or from unregistered suppliers will be overstated in box 4, which is exactly the kind of error a review against invoices catches.
What if I am not VAT-registered?
Then you file no VAT return and cannot reclaim VAT. The tool is still useful for seeing how much VAT you are paying out, and for judging how close your turnover is to the £90,000 registration threshold.
Is my statement stored?
No. Files are sent over an encrypted connection, analysed via Google's Gemini API and discarded. See the privacy policy.
