VAT Registration Threshold UK 2026: When Should a Business Register?
VAT is based on taxable turnover
Businesses usually need to register for VAT when their taxable turnover goes over the registration threshold in a rolling 12-month period, or when they expect it to exceed the threshold in the next 30 days. The test is not simply your profit and it is not always the same as your total sales.
Check the current threshold and HMRC guidance when making a decision because rates and rules can change.
What counts towards the test?
Taxable turnover generally includes sales of goods and services that are not exempt from VAT. You need to consider the nature and place of your supplies, not just the amount paid into your bank account. Exempt income and some outside-the-scope items are treated differently.
Voluntary registration
You can sometimes register before reaching the compulsory threshold. This may help a business reclaim VAT on eligible costs and appear more established to some commercial customers, but it also creates administration, pricing and cash-flow responsibilities. Registration is a business decision, not automatically a tax saving.
What happens after registration?
- Charge the correct VAT on taxable sales.
- Keep VAT records and retain supporting invoices.
- Submit VAT returns by the required deadlines.
- Pay the balance due or claim a repayment.
- Use compatible software where Making Tax Digital rules apply.
Common mistakes
- Checking turnover only once a year instead of monitoring a rolling 12-month total.
- Confusing profit with taxable turnover.
- Using the wrong VAT treatment for a supply.
- Registering late and failing to account for VAT from the effective date.
- Quoting prices without deciding whether they include VAT.
