Why de-register for VAT?
You must register for VAT with HMRC if your business’ VAT taxable turnover is more than £90,000 (2026/27 tax year).
If your VAT taxable turnover falls below the de-registration threshold of £88,000, your business can ask HMRC to cancel its VAT registration voluntarily.
In some circumstances, deregistration is mandatory. For example, you must cancel your VAT registration if your business stops trading, ceases making VAT-taxable supplies, or is no longer eligible to be VAT registered. You may also need to deregisters if your company joins a VAT group. This, according to HMRC, allows: “Two or more corporate bodies to account for VAT under a single registration number with one of the corporate bodies in the group acting as the representative member.”
