Do You Need to Register for Self-Employed VAT in the UK?

In short: Self-employed people and sole traders in the UK must register for VAT once taxable turnover exceeds £90,000 in any rolling 12-month period. You must also register if you expect to pass £90,000 in the next 30 days alone. Below the threshold, VAT registration is voluntary. It lets you reclaim VAT but adds admin.

If you're self-employed or a sole trader in the UK, you may ask yourself: do I have to register for VAT? This post explains self-employed VAT and the self-employed VAT threshold. It covers when VAT registration is mandatory and what being VAT registered means. It also covers VAT returns, accounting periods, and more. For a closer look, see A Guide to Deregistering for VAT in the UK.

What is VAT (Value Added Tax)?

Value Added Tax, or VAT, is a tax added to most goods and services at each stage of production and distribution. Businesses that are VAT-registered collect it. VAT-registered businesses must charge VAT on their sales (unless those sales are exempt). They must also submit VAT returns, and they may reclaim the VAT they paid on business purchases.

What is the self-employed VAT threshold?

• The UK VAT registration threshold is £90,000 in taxable turnover over any rolling 12‑month period. If your business’s taxable turnover goes over that, you must register for VAT.
• The £90,000 threshold came into effect in April 2024. It replaced the previous threshold of £85,000.
• “Taxable turnover” is the value of all sales of goods or services that are not VAT‑exempt or “out of scope”. It includes standard, reduced, and zero‐rated supplies. Exempt goods and services don't count toward the threshold. (GOV.UK)

When do you have to register for VAT?

You must register for VAT in the UK if either:

1. Your total taxable turnover for the last 12 months has gone over £90,000.
2. You expect your taxable turnover to go over £90,000 in the next 30 days alone.

If you went over the threshold, you must apply within 30 days of the end of that month. If you expect to go over it, you must register by the end of that 30-day period. (GOV.UK)

Once registered, you’ll get a VAT number (also called a VAT registration number). You must then charge VAT on your VAT‐liable supplies. Read more in our guide: HMRC VAT Registration Estimator Launched.

Can you register for VAT voluntarily?

Yes, you can choose to register voluntarily for VAT even if your taxable turnover is below £90,000. Voluntary registration has pros and cons:

Pros:

• You can reclaim input VAT on purchases and expenses (goods, services, equipment) that you use for the business.
• It can make your business look more established. This may help your relationships with other VAT‑registered firms.

Cons:

• You’ll need to charge VAT to your customers. If your customers are not VAT registered, this may make your prices less competitive.
• More paperwork: keeping detailed records, completing and filing regular VAT returns.

How do you register for VAT?

Self-employed people register for VAT online with HMRC in four steps. This applies whether you've gone over the £90,000 VAT threshold or you’re choosing to register voluntarily:

1. Register online via HMRC

• Most self-employed individuals and sole traders register through the HMRC VAT registration portal.

2. Prepare the required information

Have the following details ready:

• Your National Insurance number
• Details about your business (business name, address, nature of activities)
• Your bank account details
• Your expected turnover
• Your business’s accounting period (e.g., monthly, quarterly)

3. Receive your VAT certificate

Once approved, you’ll get a VAT registration certificate—usually within 30 working days. It will confirm:

• Your VAT number
• The effective date of registration
• Your first VAT return due date

Note: You must start charging VAT from your effective date of registration, even if your certificate hasn’t arrived yet.

4. Set up digital VAT returns

The UK’s Making Tax Digital (MTD) rules apply to VAT. So you must keep digital records and use MTD-compatible software (like Taxually) to submit your VAT returns.

What happens once you’re VAT registered?

Once you're a VAT-registered trader or business, you must charge VAT, keep records, and file VAT returns. Here are the key obligations:

• You’ll receive a VAT registration certificate that shows your VAT number and your effective date of registration.
• You’ll have to include VAT in your invoices for taxable goods and services. You charge the right rate for each: standard 20%, reduced, or zero.
• You must keep proper VAT records (sales, purchases, VAT on those, etc.). (GOV.UK)
• You’ll submit a VAT return to HMRC, usually every three months (an accounting period). In it, you declare the VAT you charged customers and the VAT you paid suppliers. Then you either pay the difference or claim VAT back.

What if you should have registered but didn’t?

If your taxable turnover went over the threshold and you did NOT register in time, you face several risks:

• HMRC may backdate your registration. This means you owe VAT from the date you should have registered. (GOV.UK)
• Potential penalties and interest on late VAT owed. (GOV.UK)

What special situations and accounting schemes apply?

• Simplified VAT schemes may be available, depending on your turnover or business type. They change how you calculate, reclaim, or pay VAT, and may ease the accounting burden.
• There are other triggers for VAT registration. These apply if you take over a business, or if you're based outside the UK but supply goods or services to the UK. 

Do you have to register?

Yes, you must register if your self-employed business’s taxable turnover exceeds £90,000 in any rolling 12 months. The same applies if you expect to exceed that in the next 30 days. If you're below the threshold, registration is optional (voluntary) but can have advantages. Once registered, you're legally a VAT-registered trader. You must charge VAT, submit VAT returns, keep records, and get your VAT number sorted.
