VAT THRESHOLD TRACKER

Don't get caught out by VAT

The UK VAT registration threshold is £90,000 of taxable turnover in any rolling 12‑month period — not the tax year. Enter your turnover for the last 12 months to see where you stand, and forecast when you might cross the line.

Why "rolling 12 months" and not the tax year?

HMRC checks your total taxable turnover for any 12-month period ending today — recalculated every month, not against April–April or your accounting year. That's why a strong quarter from last year can still count against you now, and why that same figure quietly drops off the back of the window a year later.

What's the 30-day "forward look" test?

Even if your rolling total below looks fine, if you have reasonable grounds to expect more than £90,000 in taxable turnover in the next 30 days alone — say, one large contract — you must register straight away. This tool tracks your rolling total, not that separate test, so a single big deal can still catch you out even while everything above shows "safe".

Registering doesn't cost you 20% of turnover — it costs you the VAT you can't reclaim or pass on. Adjust these to model your own numbers.
