Enter your monthly taxable turnover and see the rolling 12-month total against the UK VAT registration threshold. Runs entirely in your browser — nothing is uploaded.
Not tax advice. Threshold and rules change. Confirm current figures on GOV.UK VAT registration thresholds. Taxable turnover usually includes standard, reduced and zero-rated sales; exempt sales generally do not count. There is also a forward-look 30-day test if you expect to exceed the threshold in the next 30 days alone. This tool only models the rolling backward-look month-end sum.
Default £90,000 (check GOV.UK if this has changed).
Rolling window = this month and the 11 before it.
Leave blank months as 0. Figures are stored only in this browser (localStorage).
