Key takeaways

  • Register once taxable turnover passes £90,000 in a rolling 12 months
  • You have 30 days to register after crossing the threshold
  • Voluntary registration can make sense if your customers are VAT-registered
  • The Flat Rate Scheme can simplify returns for small businesses

The threshold

You must register when your VAT-taxable turnover over any rolling twelve months goes over £90,000, or when you expect it to in the next thirty days alone.

The rolling test

It isn’t your tax year or your company year: check the last twelve months at the end of every month. This is where most people get caught.

Registering early

If your customers are VAT-registered businesses, registering voluntarily can let you reclaim VAT on costs without making you dearer.
