When must I register for UK VAT?

You must register within 30 days of your taxable turnover exceeding £90,000 in any rolling 12-month period (threshold raised from £85,000 in April 2024).

Can I voluntarily register below the threshold?

Yes. Voluntary registration allows you to reclaim input VAT on purchases, which can be beneficial if you have significant business expenses.

What happens if I miss the VAT registration deadline?

HMRC can charge a penalty of 5–15% of VAT due from the date you should have registered, plus interest on unpaid VAT.
