How long does VAT registration take?

A straightforward online application is usually processed within about 10 working days, though HMRC states it can take up to 30 days, and longer if your application needs manual review, for example if there is anything unusual about your business or your details need checking. You cannot charge VAT on your invoices until your VAT number actually arrives, so factor the wait into your pricing and paperwork.

Not on your invoices, since you do not have a VAT number to show yet. You can, however, increase your prices to account for VAT and issue an interim invoice, then reissue a proper VAT invoice once your number arrives, showing the VAT you should have charged from your effective registration date.

Common delays include incomplete or inconsistent information, unusual or high-risk business activities that HMRC reviews more closely, or applying just after incorporating with very little trading history yet. Applying with accurate, complete information the first time is the best way to avoid a lengthy manual review.

Not directly, HMRC processes applications in the order received and manual reviews cannot be expedited by contacting them. The best you can do is make sure your application is complete and accurate first time, since errors or missing information are what push an application into a slower manual queue.

From your effective date of registration, which HMRC confirms when your registration is approved, this is usually the date you asked to register from, not the date the number arrives. You are liable for VAT on sales from that effective date, even if the number itself takes longer to reach you.

Keep trading normally, keep your records ready for Making Tax Digital, and prepare to reissue invoices with VAT once your number arrives. It is also worth telling regular customers you are VAT registering, particularly VAT-registered businesses, so the transition and any reissued invoices are not a surprise.
