Do I need to register for VAT?

You must register for VAT if your VAT taxable turnover goes over £90,000 in any rolling 12 month period, or if you expect it to go over that amount in the next 30 days alone.

Taxable turnover is the total of everything you sell that is not exempt from VAT, including zero rated sales. It is not the same as profit. You can also register voluntarily below the threshold.

Separate rules can apply in certain situations, for example businesses based outside the UK, distance sales and some specialist schemes, so it is worth getting advice if you are close to the threshold.
