Value Added Tax (VAT) is a tax charged on the supply of most goods and services in the UK. It is ultimately borne by the end consumer, but it is collected and administered by businesses throughout the supply chain.

VAT-registered businesses charge VAT on their sales (output tax) and reclaim VAT on their purchases (input tax). The difference, output tax minus input tax, is paid to HMRC on a periodic basis, usually quarterly.

The standard rate of VAT is 20%. A reduced rate of 5% applies to certain supplies, including domestic fuel and power and certain energy-saving materials. A zero rate (0%) applies to most food, children’s clothing, books and certain other supplies. Some supplies are exempt from VAT altogether, these include most financial services, insurance and certain healthcare services.

The distinction between zero-rated and exempt is important. Zero-rated supplies are taxable at 0%, meaning the business can reclaim input VAT on related costs. Exempt supplies are outside the VAT system, meaning input VAT on related costs generally cannot be reclaimed.

A business must register for VAT when its taxable turnover, the total of all VAT-taxable supplies, including zero-rated supplies but excluding exempt supplies, exceeds the VAT registration threshold in any rolling 12-month period. The current threshold is £90,000.

Registration is also required if the business expects its taxable turnover to exceed £90,000 in the next 30 days alone, for example, on the signing of a large contract.

Once registered, the business must charge VAT on its taxable supplies from the effective date of registration, file VAT returns (usually quarterly) and pay any VAT due.

Voluntary registration is available for businesses below the threshold. This can be advantageous where the business incurs significant VAT on its own purchases and its customers are themselves VAT-registered (and can therefore reclaim the VAT charged). It is less advantageous where customers are end consumers who cannot reclaim VAT.

The registration threshold applies on a rolling 12-month basis, not a calendar or tax year. A business that exceeds the threshold for any 12-month period, even briefly, has an obligation to register, regardless of whether it expects turnover to remain at that level.

HMRC offers several VAT accounting schemes designed to simplify administration for smaller businesses:

• Standard VAT accounting. VAT is accounted for on the basis of invoices issued and received, regardless of when payment is made. Returns are submitted quarterly.
• Cash Accounting Scheme. VAT is accounted for on the basis of cash received and paid rather than invoices. This is beneficial for businesses with customers who pay slowly, as VAT output tax is not due until the customer actually pays. Available for businesses with taxable turnover up to £1.35 million.
• Annual Accounting Scheme. Instead of quarterly returns, the business submits one annual return and makes nine monthly or three quarterly interim payments based on the previous year’s VAT liability. Available for businesses with taxable turnover up to £1.35 million.
• Flat Rate Scheme. A simplified scheme where a business pays a fixed percentage of its gross (VAT-inclusive) turnover to HMRC rather than calculating output and input VAT separately. Available for businesses with taxable turnover up to £150,000.

Each scheme has eligibility conditions and different implications for cash flow and administration. The right scheme depends on the nature of the business, its customer base and its VAT recovery position.

The Flat Rate Scheme (FRS) is a simplified VAT accounting method for smaller businesses. Instead of calculating the difference between output tax and input tax on individual transactions, the business pays HMRC a fixed percentage of its gross (VAT-inclusive) turnover.

The flat rate percentage varies by business sector, typically between 4% and 14.5%. The business continues to charge customers VAT at the standard rate (20%), but pays a lower percentage to HMRC, potentially retaining a small profit on the difference.

For example, a business in a sector with a 12% flat rate charges a customer £1,000 plus £200 VAT (£1,200 total). It pays HMRC 12% of £1,200 = £144, retaining £56.

The FRS simplifies administration but limits the ability to reclaim input VAT on purchases. A business with high VAT-bearing costs, materials, equipment, subcontractors, is likely to be better off under standard VAT accounting.

A ‘limited cost trader’ flat rate of 16.5% applies to businesses whose VAT-inclusive expenditure on goods is less than 2% of their VAT-inclusive turnover, or less than £1,000 per year. This largely eliminated the financial advantage of the FRS for many service businesses when it was introduced.

Whether the Flat Rate Scheme is advantageous depends entirely on your specific cost structure and sector rate. Run the numbers with your accountant before adopting or leaving the scheme.

Making Tax Digital (MTD) for VAT is HMRC’s requirement that VAT-registered businesses keep digital records and submit VAT returns using compatible software rather than manually entering figures into HMRC’s online portal.

MTD for VAT is now mandatory for all VAT-registered businesses regardless of turnover. The key requirements are:

• Digital records of all VAT transactions must be maintained in MTD-compatible software.
• VAT returns must be submitted directly from that software via an API link to HMRC, manual entry on the HMRC website is no longer permitted.
• There must be a digital link between each piece of software used in the preparation of the return, copy-and-paste transfers between spreadsheets are not acceptable.

Most cloud accounting software packages, including Xero, QuickBooks, Sage and FreeAgent, are MTD-compatible and submit returns directly to HMRC. Businesses using spreadsheets must use MTD-compatible bridging software to comply.

HMRC is extending the MTD programme to Income Tax Self Assessment from April 2026, starting with sole traders and landlords with income above £50,000. Directors should be aware that this programme will eventually affect their personal tax compliance as well.

Yes, subject to conditions. A VAT-registered business can reclaim input VAT on purchases where:

• The goods or services are used for taxable business purposes.
• The business holds a valid VAT invoice from the supplier.
• The supply is not subject to specific input tax blocking rules.

Items on which input VAT cannot be reclaimed include:

• Cars (unless used exclusively for business and not available for private use).
• Business entertainment, the cost of entertaining customers, suppliers or others who are not employees.
• Goods or services used for exempt activities (where partial exemption rules apply).

For mixed use, where a purchase has both business and private elements, only the business portion of the input VAT can be reclaimed.

Reclaiming input VAT on purchases made before registration is also possible in many cases: up to four years for goods still on hand at the date of registration, and up to six months for services.

Registering for VAT after the date by which registration was required is a failure to notify HMRC of a liability to be registered. HMRC treats this as a civil penalty offence.

The consequences of late registration include:

• A penalty calculated as a percentage of the net VAT due from the date registration should have occurred to the date it actually did. The percentage ranges from 5% to 15% depending on how late the registration is.
• A retrospective liability for VAT on all taxable supplies made from the date registration was required. This means VAT is calculated on income already received, and if the business did not charge VAT to its customers, the VAT must be funded from the business’s own resources.
• Interest on the late-paid VAT.

The retrospective VAT liability is often the most damaging aspect, particularly for businesses selling to end consumers who cannot reclaim the VAT and from whom the business cannot retrospectively collect it.

If you discover that your business should have registered for VAT at an earlier date, the best course of action is to register immediately and make a voluntary disclosure to HMRC. Penalties are reduced for voluntary disclosure compared to cases where HMRC identifies the failure through its own compliance activity.

Following the UK’s departure from the European Union, the VAT rules for cross-border trade changed significantly. The position now depends on whether the trade is in goods or services, and whether the customer or supplier is inside or outside the UK.

Exports of goods. The supply of goods to customers outside the UK is zero-rated for VAT purposes, provided the goods physically leave the UK and the necessary evidence is retained.

Imports of goods. VAT is charged at the point of importation. Businesses importing goods must account for import VAT, either by paying it at the border or by using Postponed VAT Accounting (PVA), which allows the VAT to be declared and reclaimed on the same VAT return, eliminating the cash flow disadvantage of paying VAT on import and reclaiming it later.

Services to overseas customers. The ‘place of supply’ rules determine where VAT is chargeable. For B2B (business-to-business) services, the general rule is that the place of supply is where the customer belongs, meaning the customer accounts for VAT in their own country under the reverse charge mechanism, and no UK VAT is charged by the supplier. For B2C (business-to-consumer) services, the rules are more complex and vary by type of service.

The interaction of post-Brexit customs procedures and VAT is complex, particularly for businesses that regularly import or export. Professional advice on the specific position for your business is recommended.
