VAT stands for value-added tax and it applies to most goods and services in the UK. It’s an indirect tax, as businesses collect it on the government’s behalf by adding VAT to the price of their goods and services.Â
Some businesses must legally register for VAT, while others can choose to do so voluntarily.Â
Registering for VAT means you must charge VAT on the products and services you sell and pay this to HMRC. However, you can also reclaim VAT on goods and services your business buys, making them cheaper than if you weren’t VAT registered.Â

There are three VAT rates in the UK, as outlined below:
Standard rate of 20%: This applies to most goods and services.
Reduced rate of 5%: This applies to some goods and services, such as home energy and children’s car seats.
Zero rate of 0%: This applies to most foods, books and children’s clothes.Â

You must register your business for VAT if your taxable turnover exceeds the VAT threshold of £90,000. This increased from £85,000 in April 2024.
Your taxable turnover is the total value of everything your business sells that’s not exempt from VAT. The threshold applies on a rolling 12-month basis, rather than a fixed period such as the tax year.Â
If your taxable turnover exceeds the £90,000 threshold at any point over 12 months, you must register for VAT within 30 days. You must also do this if you expect your taxable turnover to go over this limit within the next 30 days. Failure to do so can result in penalties.Â
If you don’t meet this threshold, there is no legal obligation to register your business for VAT. However, you can register voluntarily.Â
Before you register for VAT, make sure you have the following details to hand:
Your company registration number if you’re a limited company
Your National Insurance number and an identity document if you’re registering as an individual or partnership
Your business bank account details
Your Unique Taxpayer Reference (UTR), if you have one
Details of your annual turnover
You can then register for VAT through To do this, you need a Government Gateway user ID and password. If you don’t already have one, you must create one when you sign in.
Once registered, you receive a 9-digit VAT registration number which you must include on all invoices you raise. You also receive details on how to set up your business tax account and information about when to submit your first VAT return and payment.Â
How you charge VAT depends on your business type. If you’re a retailer, VAT is usually automatically included in the product’s price tag. For other businesses, you might include a separate line for VAT on your invoice, and the customer then pays both the product/service fee and VAT.
To calculate VAT, you multiply your price by 1.05 for a 5% VAT rate or 1.2 for a 20% VAT rate. You keep the price as it is for a zero VAT rate.
For example, if something costs £50 and you need to add the standard VAT rate of 20%, this would be £50 x 1.2 = £60.
VAT-registered businesses must sign up to Making Tax Digital (MTD) and use compatible accounting software, such as Xero, Sage or QuickBooks, to complete their VAT return and submit it online to HMRC. Alternatively, an accountant or agent could do this on your behalf. Keeping digital records can reduce the risk of mistakes.Â
You must usually submit your VAT return one month and seven days after the end of an accounting period. As this occurs every three months, you need to complete a VAT return each quarter.Â
Your return shows the VAT you’ve collected on sales and the VAT paid on purchases. If you’ve collected more VAT than you’ve paid, you must pay the difference to HMRC. On the other hand, if you’ve paid more VAT on purchases than you’ve collected, you can reclaim the difference. HMRC usually repays this within 30 days.
Example:
The total VAT you’ve collected (your output VAT) is £4,000
The total VAT you’ve paid (your input VAT) is £2,500
You deduct £2,500 from £4,000, leaving you with £1,500 to pay to HMRC
Alternatively, if your output VAT was £2,500 and your input VAT was £4,000, you could reclaim £1,500 from HMRC.
If you exceed the VAT threshold in any 12-month period, you must register for VAT. However, if your taxable turnover is under this limit, you might want to consider registering voluntarily. Whether this is suitable for your business likely depends on the type of business you run.Â
One of the biggest advantages of registering is you can claim back the VAT you pay on items you buy for your business. This is particularly beneficial for businesses that buy large quantities of goods from suppliers charging VAT. Â
Registering for VAT also makes your business look more credible and trustworthy to clients and investors, and it might even encourage partnerships with other VAT-registered businesses.
However, if you decide to register for VAT, prepare yourself for more paperwork – it’s important to keep accurate records and you must submit quarterly VAT returns. You must also remember to pay your tax on time. What’s more, if the amount of VAT you need to pay outweighs the amount you can claim back, you could end up with an expensive tax bill to pay.
If you don’t legally need to register your business for VAT, it’s crucial to weigh up the pros and cons of being VAT registered before proceeding. It can also be worth seeking advice from a tax advisor or accountant.
