Build and check your VAT return CSV

Box 3 and Box 5 are worked out for you. Nothing you type leaves your browser.

How to lay out your spreadsheet

  1. A sales tab: one row per sale, with the date, customer, net amount, VAT rate and VAT.
  2. A purchases tab: one row per purchase, with the date, supplier, net amount and the VAT you can reclaim.
  3. A VAT summary tab: nine rows, Box 1 to Box 9, each worked out by a formula from the other tabs, such as a SUMIFS on the dates in the VAT period.

Linked cells and formulas between tabs count as digital links. Keep the summary tab in the same layout as our sample CSV: the box name in the first column and the amount in the second.

What goes in each box

BoxWhat it shows
Box 1VAT due on sales and other outputs
Box 2VAT due on goods brought into Northern Ireland from the EU
Box 3Box 1 plus Box 2
Box 4VAT you are reclaiming on purchases
Box 5The difference between Box 3 and Box 4: what you pay or get back
Box 6Total sales, excluding VAT, in whole pounds
Box 7Total purchases, excluding VAT, in whole pounds
Box 8Goods supplied from Northern Ireland to the EU, in whole pounds
Box 9Goods acquired from the EU into Northern Ireland, in whole pounds

Most businesses in Great Britain leave Boxes 2, 8 and 9 at zero.

How to save the CSV

  • Excel: open the VAT summary tab, choose File, Save As, and pick CSV (Comma delimited). Only the open tab is saved.
  • Google Sheets: open the VAT summary tab, choose File, Download, Comma-separated values (.csv).
  • From other software: if your till, shop or bookkeeping tool can export a VAT summary, save it as CSV in the same layout.

Checks before you upload

  • Box 3 equals Box 1 plus Box 2.
  • Box 5 is the difference between Box 3 and Box 4, and is never negative.
  • Boxes 6 to 9 are whole pounds, with no pence.
  • The dates in your formulas match the VAT period you are filing.

Final thoughts

You do not need accounting software to file from a spreadsheet. Keep your records in tabs, let formulas total the nine boxes, save a CSV and upload it to bridging software. That keeps you within the Making Tax Digital rules.

Disclaimer: This guide gives general information, not advice for your business. If you are unsure how the rules apply to you, speak to an accountant or contact HMRC.

Frequently asked questions

Checked against HMRC VAT Notice 700/22 (digital links), VAT Notice 700/12 and Swift VAT Pro's CSV format. November 2026.

Can I submit my VAT return from Excel?

Yes. Keep your records in Excel, total the nine boxes with formulas, save the summary as a CSV and upload it to MTD bridging software, which submits it to HMRC.

Can I use Google Sheets for Making Tax Digital?

Yes. Google Sheets works the same way: keep your records in it, total the nine boxes with formulas, then download the summary as a CSV and upload it.

Is copying figures from a spreadsheet allowed under MTD?

No. Typing or copying and pasting your totals is not a digital link. Uploading a CSV saved from your spreadsheet is.

What format should my VAT CSV be in?

Nine rows, Box 1 to Box 9, with the box name in the first column and the amount in the second. Download our sample CSV to see the layout.

Do Boxes 6 to 9 need to be whole pounds?

Yes. HMRC only accepts whole pounds in Boxes 6 to 9. Boxes 1 to 5 can include pence.
