Threshold
Registration is more than £90,000. A registered business can ask to cancel below £88,000.
The deadline rule, in GOV.UK's own example
If the rolling total first goes over the threshold on 15 July, you must register by 30 August. The effective date of registration is 1 September. That is 30 days after the end of July, and the first day of the second month after July. The date field above applies that rule to the date you enter. It does not apply to the next-30-days test, where the effective date is the day you realised.
These thresholds do not follow the 6 April tax year. The figures are the ones GOV.UK publishes now. VAT Notice 700/1's history table lists £90,000 through 31 March 2026 and does not yet print a later row; the live threshold pages still state £90,000 and £88,000.
