What is the VAT threshold?

How we worked it out

  1. £80,000 last 12 months against the £90,000 threshold
  2. £90,000 − £80,000 = £10,000 to go

Your registration deadline and start date

If your last 12 months go over the threshold, register within 30 days of the end of the month you went over. Your VAT registration then starts on the first day of the second month after. Going over in means registering by and starting on .

If you expect to go over in the next 30 days alone, your registration starts on the day you realised. GOV.UK says to register by the end of that 30-day period.
