Did you know that over 90% of UK businesses are VAT registered or required to be? For many small business owners, understanding when and how to register for VAT can be a complex but crucial step in managing finances effectively. In the 2026/26 tax year, knowing the correct VAT registration thresholds and processes is essential to stay compliant and avoid penalties.
| VAT Registration Thresholds and Key Figures (2026/27) | Amount (£) |
|---|---|
| VAT Registration Threshold (taxable turnover in previous 12 months) | 90,000 |
| VAT Deregistration Threshold (turnover falls below) | 83,000 |
| Standard VAT Rate | 20% |
| Reduced VAT Rate (e.g. some energy supplies) | 5% |
| VAT Registration Deadline (from exceeding threshold) | 30 days |

Taxable turnover includes all sales of goods and services that are subject to VAT, excluding VAT-exempt and out-of-scope supplies.
It’s important to monitor your turnover regularly because if you exceed the threshold, you must notify HMRC and register for VAT within 30 days from the end of the month in which the threshold was exceeded. Failure to do so can result in penalties and backdated VAT payments.
Additionally, if you expect to exceed the threshold in the next 30 days, you must register immediately. This protects you from non-compliance even if your actual turnover has not yet reached £90,000.
Voluntary VAT Registration: Is It Right for Your Business?
Even if your turnover is below the £90,000 threshold, you can choose to register voluntarily for VAT. This might be beneficial if you regularly incur VAT on business expenses and want to reclaim it, or if your customers are mainly VAT-registered businesses that can reclaim VAT themselves.
Voluntary registration can also enhance your business’s credibility, as some customers prefer dealing with VAT-registered suppliers. However, it comes with administrative responsibilities, such as submitting VAT returns regularly and charging VAT on your sales.
Before registering voluntarily, consider the following:
- You will need to charge VAT on all eligible sales, which could affect pricing and competitiveness.
- You can reclaim VAT on business purchases, which may improve cash flow.
- VAT returns must be submitted, typically quarterly, requiring accurate record-keeping.
- Your accounting systems should be capable of handling VAT requirements.

How to Register for VAT with HMRC
Registering for VAT is a straightforward process, but it must be done correctly to avoid delays. The easiest and fastest way is to register online via the HMRC website. You will need to create a Government Gateway account if you do not already have one.
Here’s what you’ll need to complete the VAT registration:
- Your business details, such as trading name, address, and contact information.
- Your Unique Taxpayer Reference (UTR) issued by HMRC.
- Details of your business turnover and activities.
- Bank account details for VAT payments or refunds.
- Information about any associated businesses or partnerships.
After submitting your application, HMRC will usually process it within 10 working days. They will send you a VAT registration certificate that includes your VAT number, the date your registration takes effect, and deadlines for submitting your first VAT return.
Registering as a Sole Trader vs Limited Company
Whether you are a sole trader or running a limited company, the VAT registration process is similar, but there are some differences in documentation and how VAT affects your accounts. Sole traders register using their personal details and UTR, while limited companies use their company registration number (CRN) from Companies House.

What Happens After You Register for VAT?
Once registered, you must start charging VAT on all eligible sales from the effective date on your VAT certificate. You will also be able to reclaim VAT on your business purchases made after this date.
HMRC requires VAT-registered businesses to submit regular VAT returns, usually quarterly. These returns detail the VAT you’ve charged and the VAT you’ve paid, with any difference payable to or refundable from HMRC.
It is important to keep accurate VAT records, including invoices, receipts, and import/export documents, for at least six years as required by law.
Failure to comply with VAT obligations may lead to penalties, interest charges, or even investigations by HMRC.
