When Do I Need to Register for VAT?
VAT registration can feel confusing when your business starts to grow. Many sole traders, limited companies and small business owners are unsure when they need to register, how the VAT threshold works, and what happens if they register late.
The simple answer is this: you must register for VAT if your VAT-taxable turnover goes over £90,000 in any rolling 12-month period. You must also register if you expect your taxable turnover to go over £90,000 in the next 30 days alone. This is the current UK VAT registration threshold, which increased from £85,000 to £90,000 from 1 April 2024.
For many businesses, the tricky part is not the threshold itself. It is knowing what counts towards it, when to check it, and when to tell HMRC.
What Is VAT?
VAT stands for Value Added Tax. It is a tax added to many goods and services sold by businesses in the UK.
Once your business is VAT registered, you usually need to:
- charge VAT on taxable sales
- submit VAT returns to HMRC
- keep proper VAT records
- pay any VAT owed to HMRC
- follow Making Tax Digital rules for VAT
You may also be able to reclaim VAT on many business purchases. This can be useful if your business has regular costs, stock, equipment or materials.
When Do You Have to Register for VAT?
You need to register for VAT if either of these applies:
Your turnover has gone over £90,000
You must register if your total VAT-taxable turnover for the last 12 months is more than £90,000. This is not based on the tax year or calendar year. It is a rolling 12-month period, so you need to keep checking it as your business grows.
For example, if you check your figures at the end of June, you should look back over the previous 12 months, not just from April to June.
You expect to go over £90,000 in the next 30 days
You must also register if you realise your taxable turnover will go over £90,000 in the next 30 days. HMRC states that you must register by the end of that 30-day period. Your effective date of registration is the date you realised you would exceed the threshold.
This can happen if you win a large contract, take on a major project, or receive a sudden rise in orders.
What Counts Towards the VAT Threshold?
The VAT threshold is based on your VAT-taxable turnover, not your profit.
This means you need to include sales that would be subject to VAT if your business was VAT registered. This may include goods and services charged at the standard, reduced or zero rate of VAT.
It does not usually include VAT-exempt income. It also does not include money that is not part of your taxable sales, such as business loans.
This is where many business owners get caught out. Your taxable turnover is not the same as the amount of money left after expenses. Even if your profit is much lower, you may still need to register if your sales pass the VAT threshold.
How Soon Do You Need to Register?
If your taxable turnover has gone over the threshold, you must usually register within 30 days of the end of the month in which you exceeded it. Your VAT registration date will normally be the first day of the second month after you went over the threshold.
If you expect to exceed the threshold in the next 30 days, the rules are different. You must register by the end of that 30-day period. Your registration date is the date you realised you would go over the threshold.
Because of this, it is important to review your turnover often. A quick monthly check can help you avoid late registration.
Can You Register for VAT Before You Reach the Threshold?
Yes, you can register for VAT voluntarily even if your turnover is below £90,000.
Some businesses choose to do this because it allows them to reclaim VAT on eligible business costs. It can also make a business appear more established, especially when working with larger companies or VAT-registered clients.
However, voluntary VAT registration is not always the best choice. Once registered, you will need to charge VAT on taxable sales and submit VAT returns. This can affect your pricing, especially if your customers are members of the public or small businesses that cannot reclaim VAT.
Before registering voluntarily, it is worth getting advice from an accountant.
What Happens After You Register for VAT?
Once your business is VAT registered, HMRC will give you a VAT registration number. You will then need to add VAT to your taxable sales from your effective date of registration.
You will also need to:
- issue VAT invoices where needed
- keep digital VAT records
- submit VAT returns
- pay VAT to HMRC on time
- keep track of VAT on business purchases
Most VAT-registered businesses submit VAT returns every quarter. Your return shows how much VAT you charged customers and how much VAT you paid on business costs.
If you charged more VAT than you paid, you usually pay the difference to HMRC. If you paid more VAT than you charged, you may be able to claim a repayment.
What Happens If You Register Late?
If you register late, you may still need to pay VAT from the date you should have been registered. HMRC may also charge interest or penalties, depending on the circumstances.
Late registration can be difficult because you may not have charged VAT to your customers at the time. This means the VAT may have to come out of your own business income.
For example, if you should have charged VAT on past sales but did not, HMRC may still expect you to account for that VAT. This is why it is much better to register on time.
Can You Deregister for VAT?
You may be able to cancel your VAT registration if your taxable turnover falls below the deregistration threshold. The current VAT deregistration threshold is £88,000.
This may apply if your business has become smaller, you have changed your services, or you no longer expect your taxable sales to stay above the threshold.
However, deregistering can have tax and cash flow effects, so it is sensible to speak to an accountant before making the change.
