VAT registration check
Registration likely required
Projected VATable turnover exceeds £90,000, so the HMRC threshold is likely met.
- Current threshold check uses 12-month VATable turnover at £1,000,000.
- HMRC’s registration threshold is more than £90,000 in annual taxable turnover.
- VAT must be registered within 30 days of crossing the threshold in a 12-month period.
Large VAT imbalance
If this swings a lot after inputting realistic expenses, check your VATability assumptions and seek a review.

VAT calculator FAQs
Quick answers before you decide on registration.
What threshold does this check use?
This estimate uses HMRC's current UK VAT registration threshold of more than £90,000 taxable turnover in a rolling 12-month period.
Does the result include partial exemption or flat-rate VAT?
No. Partial exemption methods, flat-rate schemes, margin schemes, imports, and some digital adjustments are excluded to keep this as a fast estimate.
Can I use this for zero-rated or exempt turnover?
Use a proportionate VATable turnover figure. Zero-rated sales still generate output VAT at 0% and still count toward total taxable turnover for threshold purposes.
Already crossing the threshold?
If this is your first time planning VAT, we can review registration timing, scheme choice, and filing setup in 20 minutes.
