🔢 What is a VAT Number?

A VAT number (Value Added Tax) is a unique identifier assigned to businesses that are registered for VAT with HMRC (Her Majesty's Revenue and Customs) in the UK. If you plan to do business in the UK or sell to UK-based customers, having a VAT number may be required.

✅ When Do You Need to Register for VAT?

You must register for VAT in the UK if:

• Your taxable turnover exceeds £85,000 in a 12-month period (as of 2025)

• You expect to exceed the threshold in the next 30 days

• You sell goods or services to UK customers from abroad (certain cases)

• You voluntarily choose to register to reclaim VAT on business expenses
