Guide

Understand when VAT registration may be needed

This calculator helps UK businesses compare rolling taxable turnover with the VAT registration threshold and spot when the next step may be required.

Enter your total sales for the last rolling 12 months, not just your last financial year.
Enter VAT-exempt sales separately so the calculator can estimate taxable turnover.
Add expected taxable sales for the next 30 days if you know a large contract or billing period is coming up.
Review the status, taxable turnover, and threshold headroom shown in the result panel.

Below threshold means your entered taxable turnover is under the current VAT registration threshold.
Approaching threshold means your entered turnover is close enough to monitor more frequently.
Registration likely required means your entered figures exceed the threshold or expected next 30-day taxable sales exceed it.
Headroom remaining shows the estimated gap between entered taxable turnover and the registration threshold.

Use taxable sales only. VAT-exempt income is not counted towards taxable turnover.
Use a rolling 12-month period rather than a fixed tax year or accounting year.
Check whether connected businesses or business transfers affect your registration position.
Keep evidence for turnover checks, including invoices, sales reports, and accounting software exports.

Taxable turnover is the total value of sales that are not VAT-exempt. It includes zero-rated sales but excludes exempt sales.

Yes. Some businesses register voluntarily below the threshold, but the decision depends on customers, costs, and cash flow.

No. It only estimates your position from the figures entered on the page.

AMS can review your turnover, confirm what counts towards VAT registration, and help with registration, bookkeeping, and VAT returns.
