VAT Threshold Explained for Small Business Owners

Understanding the VAT threshold is essential for any sole trader or small business selling goods and services in the UK. Once your VAT taxable turnover exceeds the VAT registration threshold, you may need to register for VAT, begin charging VAT and submit regular VAT returns to HMRC.

The current VAT registration threshold is £90,000. However, registration is not based only on your turnover during a fixed tax year or accounting period. You must monitor taxable turnover over every rolling 12-month period and consider whether you expect to exceed the threshold within the next 30 days.

This guide explains how the UK VAT threshold works, which sales count towards it, when compulsory VAT registration applies and whether voluntary registration could benefit your business.

What Is VAT?

Value Added Tax, usually shortened to VAT, is a tax applied to most goods and services sold by VAT-registered businesses in the UK.

A VAT-registered business normally charges VAT on its taxable sales. This is known as output VAT. The business may then reclaim VAT paid on eligible business purchases, which is known as input VAT. The difference between the output VAT collected and input VAT reclaimed will usually determine the VAT payment due to HMRC or the repayment owed to the business.

The standard VAT rate is 20%, although some goods and services are charged at the reduced rate of 5% or the zero rate of 0%. Other supplies are VAT exempt or outside the scope of the VAT system. The current rates and the types of goods and services to which they apply are explained in the government’s VAT rates guidance.

What Is the Current VAT Registration Threshold?

The current UK VAT threshold is £90,000. This threshold has applied since 1 April 2024.

You must register for VAT when either your VAT taxable turnover for the previous 12 months exceeds £90,000 or you expect your taxable turnover to exceed £90,000 within the next 30 days alone.

The first test looks backwards over a rolling 12-month period. It does not relate only to the tax year, calendar year or your business’s annual accounting period. This means small businesses should calculate taxable turnover regularly rather than waiting until they prepare their annual accounts.

The second test looks forward. If you expect the total value of taxable supplies to exceed the VAT threshold during a single 30-day period, you must register regardless of your turnover during the previous year.

What Is VAT Taxable Turnover?

VAT taxable turnover is the total value of everything your business sells that is not exempt from VAT or outside the scope of UK VAT.

It normally includes standard-rated, reduced-rated and zero-rated goods and services. Zero-rated supplies count towards taxable turnover even though the VAT rate charged to the customer is 0%.

Sales that are VAT exempt do not normally contribute towards the registration threshold. Examples of potentially exempt supplies include certain financial, insurance, educational and healthcare services, although the precise treatment depends on the nature of the transaction.

Taxable turnover may also include goods hired or loaned to customers, business goods used personally, goods exchanged through barter arrangements and certain reverse-charge services received from overseas.

When calculating your annual taxable turnover, use the value of taxable sales excluding VAT.

How Does the Rolling 12-Month Test Work?

The rolling test requires you to review taxable turnover for the previous 12 months at the end of every month.

For example, when checking your turnover at the end of July, you would review taxable sales from the beginning of the previous August to the end of the current July.

At the end of August, the calculation moves forward by one month.

This differs from simply checking annual turnover at the end of your accounting year. A fast-growing business could exceed the VAT threshold partway through the year and create a compulsory VAT registration requirement before its annual accounts are prepared.

Monitoring turnover monthly is crucial. Accounting software can help business owners track taxable sales and identify when turnover is approaching the current VAT threshold.

When Must a Business Register for VAT?

If your taxable turnover exceeds the VAT threshold under the rolling 12-month test, you generally need to notify HMRC within 30 days of the end of the month in which the threshold was exceeded.

Your effective registration date will normally be the first day of the second month after you exceeded the threshold.

For example, if your rolling taxable turnover exceeds £90,000 during July, you would generally need to notify HMRC by 30 August. Your effective registration date would usually be 1 September.

Different timing rules apply if you expect turnover to exceed £90,000 within the next 30 days alone. In this situation, you must register by the end of that 30-day period, and your effective registration date is normally the date on which you first realised the threshold would be exceeded.

Businesses can usually register for VAT online. Once registration is complete, HMRC will issue a VAT registration number and confirm the effective registration date.

What Happens If a Business Temporarily Exceeds the Threshold?

A business that temporarily exceeds the VAT threshold may be able to apply for an exception from registration.

HMRC must be satisfied that the taxable turnover will not exceed the deregistration threshold during the following 12 months. You should provide evidence explaining why turnover increased and why you reasonably expect it to fall.

An exception is not automatic. The business must still notify HMRC that it has exceeded the VAT registration threshold and formally request an exception.

The process is explained in HMRC’s guidance on applying for a VAT registration exception.

If HMRC rejects the application, the business must register and account for VAT from the appropriate effective registration date.

What Is the VAT Deregistration Threshold?

The current VAT deregistration threshold is £88,000.

A VAT-registered business may be able to cancel its registration if it can satisfy HMRC that its taxable turnover during the next 12 months will not exceed £88,000. However, a business is not required to deregister simply because turnover falls below that amount.

Remaining VAT registered may continue to be beneficial where a business has significant VATable costs or mainly supplies other VAT-registered businesses. The decision should account for input VAT recovery, administrative work, pricing and the likely effect on customers.

Can a Business Register for VAT Voluntarily?

A business can register for VAT voluntarily even when its taxable turnover is below £90,000.

Voluntary VAT registration may allow the business to reclaim VAT paid on eligible goods, services and business costs. This can be valuable for a new business making significant purchases or a company whose customers are mainly VAT registered and can recover the VAT charged.

Voluntary registration can also make a business appear more established to some customers because a VAT registration number does not reveal whether registration was compulsory.

However, voluntary VAT registration creates the same core responsibilities as compulsory registration. The business must maintain appropriate VAT records, issue valid VAT invoices, submit VAT returns, follow Making Tax Digital requirements and pay any VAT due.

A business should therefore consider whether the potential input VAT recovery outweighs the additional administration and impact on pricing.

How VAT Registration Affects Pricing

VAT registration can significantly affect pricing strategies, particularly when customers are individuals or businesses that cannot reclaim VAT.

A business making standard-rated supplies will normally add 20% VAT to its net selling price. If it previously charged £100 for a service, it may begin charging £120 after VAT registration.

The alternative is to keep the final customer price at £100 and absorb the VAT within that amount. This reduces the net income retained by the business and may affect profitability.

For businesses selling mainly to VAT-registered customers, charging VAT may have less commercial impact because those customers can normally reclaim eligible input tax. Businesses selling directly to consumers may need to assess pricing more carefully.

How VAT Registration Affects Cash Flow

Registering for VAT changes the way money moves through a business.

VAT collected from customers is not business income. It is money that may need to be paid to HMRC after deducting eligible input VAT. Businesses should avoid treating the full amount received from customers as available cash.

Late-paying customers can also create pressure under regular VAT accounting because the business may need to report output VAT before receiving payment. A suitable VAT accounting scheme may help manage this issue.

Regular cash flow forecasting allows business owners to plan ahead for each VAT bill and prevent money reserved for HMRC from being used for other expenses.

Reclaiming VAT on Business Purchases

Once registered, a business can usually reclaim VAT paid on eligible purchases that relate to its taxable business activities.

To claim VAT, the business must normally hold a valid VAT invoice and keep records showing that the purchase was made for business purposes. Where an expense has both business and personal use, only the business element may be recoverable.

Input VAT may be restricted on certain costs, including client entertainment, cars and purchases connected with VAT-exempt activities.

In some circumstances, a newly registered business may also reclaim VAT on qualifying purchases made before registration. Different time limits apply to goods and services, and the business must still hold the necessary evidence.

HMRC’s guidance explains how businesses can reclaim VAT on business expenses.

Charging VAT and Issuing Sales Invoices

A business must not charge VAT before its effective registration date.

After registration, the business should include its VAT registration number on valid VAT invoices and show the appropriate VAT rate, net value, VAT amount and total payable.

If the VAT registration number has not yet arrived but the effective registration date has passed, the business may need to adjust its invoicing process temporarily and issue replacement VAT invoices once the number is available.

Accurate sales invoices are essential because customers may rely on them to reclaim input VAT.

VAT Returns and Payment Deadlines

VAT-registered businesses usually submit a VAT return every three months, although the precise period depends on the VAT stagger assigned by HMRC or the accounting scheme selected.

A VAT return reports output VAT charged on sales, input VAT reclaimed on purchases and the resulting amount payable to HMRC or reclaimable by the business.

The standard filing and payment deadline is normally one calendar month and seven days after the end of the VAT accounting period. Businesses should check their VAT account for the exact deadline.

Even when there is no VAT to pay or reclaim, a return must generally still be submitted.

Making Tax Digital for VAT

Most VAT-registered businesses must comply with Making Tax Digital for VAT.

This requires businesses to maintain specified VAT records digitally and use compatible software to submit VAT returns to HMRC. Copying figures manually from paper records into the VAT return is not normally sufficient unless a permitted digital process is used.

Compatible accounting software can record sales, purchases, VAT rates and payments while maintaining the digital connections required for reporting.

Current obligations are explained in HMRC’s Making Tax Digital for VAT guidance.

Which VAT Accounting Schemes Are Available?

VAT accounting schemes can simplify reporting or help businesses manage cash flow. Eligibility depends on taxable turnover, business activities and compliance history.

The correct scheme is not necessarily the same for every small business. It should be chosen after considering customer payment patterns, business purchases, expected growth and the amount of input VAT normally reclaimed.

The VAT Cash Accounting Scheme

Under regular VAT accounting, a business generally accounts for VAT according to invoice dates, even if customers have not yet paid.

The Cash Accounting Scheme allows eligible businesses to pay VAT on sales when customers pay. Input VAT is then reclaimed when the business pays its suppliers.

This can support cash flow where customers regularly pay invoices late. To join, estimated VAT taxable turnover must generally be £1.35 million or less.

Businesses do not normally need to apply before using cash accounting, but they must meet the eligibility conditions and operate the scheme correctly.

The government’s VAT Cash Accounting Scheme guidance explains how the scheme works.

The Annual Accounting VAT Scheme

Under standard arrangements, businesses usually submit four VAT returns each year.

The Annual Accounting Scheme allows an eligible VAT-registered business to submit one VAT return annually. The business normally makes advance VAT payments throughout the year, followed by a balancing payment or repayment after submitting the annual return.

This may reduce administration and make VAT payments more predictable. However, it can be less suitable for businesses that regularly reclaim VAT because refunds are generally received only after the annual VAT return is submitted.

Businesses can normally join if estimated VAT-taxable turnover is £1.35 million or less.

The Flat Rate Scheme

The Flat Rate Scheme allows an eligible small business to calculate its VAT payment as a fixed percentage of VAT-inclusive turnover. The percentage depends on the business sector.

The business generally continues charging customers the normal VAT rate but pays HMRC using the relevant flat rate. In most cases, it cannot reclaim input VAT separately, apart from certain qualifying capital purchases.

Businesses can usually join the scheme if expected taxable turnover excluding VAT is £150,000 or less.

The scheme is not automatically cheaper. The limited-cost business rules, sector percentage and level of VATable expenditure can all affect whether it produces a saving. HMRC provides further details in its Flat Rate Scheme guidance.

VAT Rules for Businesses Based Outside the UK

A non-established taxable person is a business that does not have a UK establishment but makes taxable supplies in the UK.

The standard £90,000 VAT registration threshold does not generally apply to a non-established taxable person. A business based outside the UK may need to register as soon as it makes, or expects to make, taxable supplies in the UK.

Special rules can also apply to goods moving between Northern Ireland and the EU. Businesses involved in international trade should obtain advice based on the location of the business, customers and goods.

What Happens If You Register Late?

Failure to register for VAT on time can result in the business owing VAT from the date it should have been registered, even if it did not charge VAT to its customers at the time.

This may require the business to fund VAT from its own money or approach customers to correct earlier invoices. HMRC may also charge penalties and interest depending on the circumstances.

Businesses approaching the registration threshold should therefore monitor turnover monthly, retain accurate sales records and seek advice before the threshold is exceeded.

Should Your Small Business Register Voluntarily?

Voluntary registration may be appropriate when the business has substantial VATable purchases, works mainly with VAT-registered customers or expects to exceed the threshold soon.

It may be less attractive when customers are consumers, prices are highly competitive or most business costs contain little recoverable VAT.

Before registering voluntarily, consider the effect on customer prices, profit margins, VAT recovery, cash flow, accounting software and administrative responsibilities.

A professional assessment can help determine whether voluntary registration is likely to save money or simply create additional work.

How 10 Chartered Accountants Can Help

VAT registration involves more than completing an online form. Businesses must identify the correct effective registration date, understand which sales are taxable, select suitable VAT accounting schemes and configure their accounting records correctly.

Conclusion

The VAT registration threshold is £90,000 and is measured using taxable turnover over a rolling 12-month period. Businesses must also register if they expect to exceed £90,000 within the next 30 days alone.

Taxable turnover includes standard-rated, reduced-rated and zero-rated sales, while VAT-exempt supplies generally do not count. Businesses below the threshold may register voluntarily, but they should carefully consider the effect on pricing, cash flow and administration.

Once registered, businesses must charge the correct VAT rates, maintain digital records, submit VAT returns and pay HMRC on time. Choosing an appropriate VAT scheme can simplify these responsibilities, but the right decision depends on the business’s sales, costs and payment patterns.
