The best digital VAT software for a small business is the one that gets the boxes right. Vatnix shows you the figures first, free.
The arithmetic behind a UK VAT return, worked from your own figures: any receipt or invoice split into net and VAT at 20%, 5% or zero, the box of the return each total lands in, the £90,000 rolling-twelve-month registration threshold, and the free Making Tax Digital software compared on the one thing that decides it. Free on the page, no account, no trial clock. Vatnix Pro keeps the quarters, the figures and the digital records Making Tax Digital asks you to keep. We work out the numbers; HMRC-recognised software files them.
Built for one tax, for one job
Vatnix is not an accountant, a bookkeeping service, a general ledger or an HMRC filing agent, and it is not going to become one. Every field on every screen is there because the VAT return needs it.
Work the VAT. Read the boxes. Keep the records behind both.
- Net, VAT and gross from any figure, at any UK rate. Type the number on the receipt, say whether it already includes VAT and at which rate, and get the split back. The VAT on a £120.00 standard-rated receipt is £20.00, and the tool shows why it is one sixth of the total rather than a fifth of it.
- Which box every total lands in. Sales and purchases sorted into the boxes the return asks for: the net of a purchase into box 7 and its VAT into box 4, the net of a sale into box 6 and its VAT into box 1, so the return is a total rather than a guess.
- Quarters kept, threshold tracked, everything exportable. Every quarter saved with the figures behind each box, the rolling twelve-month taxable turnover tracked against the £90,000 threshold, and the digital records Making Tax Digital asks for, ready to hand to whoever submits the return.
The free tools
Every tool computes its answer on the page, free, with no account. Put in your own figure, say whether it already includes VAT and at which rate, and the calculator prints the net, the VAT and the gross, plus the box of the return each one belongs in, with the method under every figure. Change any input and the answer updates as you type. The rates come from GOV.UK and are cited under the tool.
- VAT receipt: Split any VAT receipt: a figure and a rate into the net, the VAT and the gross, and the box of the VAT return each total belongs in.

The calculators and their answers are free forever.
