Introduction to VAT

Value Added Tax (VAT) is a consumption tax charged on most goods and services sold by VAT-registered businesses in the UK. Unlike Corporation Tax, which is levied on your profits, VAT is charged on the value you add at each stage of the supply chain. As a business owner, you collect VAT from your customers, reclaim VAT on your business purchases, and pay the difference to HMRC.

For many small business owners, VAT feels like the most complex part of running their company. The registration rules, multiple rate bands, various accounting schemes, and the shift to Making Tax Digital create a system that can seem overwhelming. But once you understand the fundamentals, VAT becomes a manageable, predictable process.

This guide is written for directors of UK limited companies and small business owners with annual revenue between roughly 50,000 and 500,000. Whether you are approaching the VAT registration threshold for the first time, already registered and trying to choose the right scheme, or simply want to understand your obligations better, every section is written with your situation in mind.

We cover every aspect of VAT that matters to a small business: when you must register, which rates apply to your sales, how to choose between VAT accounting schemes, what goes on your VAT return, how Making Tax Digital affects you, how input and output VAT work in practice, special rules for international trade and specific transaction types, and the most common mistakes businesses make. All rates and thresholds are for the 2025/26 tax year.

How VAT Works in Practice

The mechanics of VAT are straightforward once you see them in action. Suppose you are a consultant and you invoice a client 1,000 plus VAT. You charge them 1,200 (1,000 + 20% VAT = 200). That 200 is output VAT, which you owe to HMRC. During the same period, you buy a laptop for 600 plus VAT, paying 720 (600 + 120 VAT). That 120 is input VAT, which you can reclaim from HMRC. On your VAT return, you report output VAT of 200 minus input VAT of 120, and you pay the net amount of 80 to HMRC.

The key insight is that VAT is not your money. You are acting as a collection agent for HMRC. The VAT you charge customers belongs to HMRC, and the VAT you pay on business purchases is refunded to you. When managed properly, VAT is cash-flow neutral for your business. The challenge lies in keeping accurate records, filing on time, and understanding which rates and rules apply to your specific transactions.

If you are brand new to running a limited company, you may want to read our complete limited company tax guide alongside this one, as it covers Corporation Tax, salary vs dividends, and other obligations that interact with your VAT position.

VAT Registration

VAT registration is the process of signing up with HMRC to charge, collect, and remit VAT. Whether registration is compulsory or voluntary determines your obligations and the consequences of not registering. Understanding the thresholds and timing is essential because late registration carries penalties.

The 90,000 Threshold

For the 2025/26 tax year, you must register for VAT if either of the following conditions is met:

  • Historical test: Your taxable turnover exceeded 90,000 in any rolling 12-month period. You must register within 30 days of the end of the month in which you breached the threshold. Your registration becomes effective from the first day of the second month after you exceeded the threshold.
  • Future test: At any point, you expect your taxable turnover to exceed 90,000 in the next 30 days alone (for example, you land a single large contract). You must register immediately, and your registration takes effect from the date you formed that expectation.

Taxable turnover includes all sales that are standard-rated (20%), reduced-rate (5%), and zero-rated (0%). It does not include exempt supplies or income outside the scope of VAT. This distinction matters: if a significant portion of your revenue is exempt, you may be further from the threshold than you think.

Voluntary Registration

If your turnover is below 90,000, you can choose to register voluntarily. This can be advantageous in several situations:

  • B2B clients: If most of your customers are VAT-registered businesses, they can reclaim the VAT you charge. Your effective price to them does not change, but you can reclaim VAT on your purchases.
  • High input VAT: If you have significant business purchases that include VAT (equipment, stock, office costs), registering lets you reclaim that VAT. This can improve cash flow substantially.
  • Credibility: Being VAT-registered can signal to potential clients and suppliers that your business is established and operating at scale.
  • Pre-registration recovery: When you register, you can reclaim VAT on goods purchased up to 4 years before registration (if still on hand) and services purchased up to 6 months before. This can provide a useful one-off cash injection.

However, voluntary registration adds administrative burden. You must file quarterly returns (or use an alternative scheme), keep detailed digital records, and comply with Making Tax Digital requirements. If your clients are mainly consumers who cannot reclaim VAT, registration effectively increases your prices by 20%. Weigh the pros and cons carefully. Our guide on voluntary registration covers the decision in detail.

How to Register

You register for VAT online through your HMRC Government Gateway account. The process typically takes 5 to 10 working days, though it can take up to 30 days during busy periods. You will need:

  • Your company's Unique Taxpayer Reference (UTR)
  • Your Companies House registration number
  • Your bank account details
  • Your estimated taxable turnover for the next 12 months
  • Details of the date you exceeded (or expect to exceed) the threshold

Once registered, HMRC will issue your VAT registration number (a 9-digit number prefixed with GB for UK businesses). You must display this on all VAT invoices. HMRC will also assign your VAT accounting periods (quarters), which you can request to change if they do not align with your business cycle.

For a step-by-step walkthrough, see our VAT registration guide.

The Deregistration Threshold

The VAT deregistration threshold for 2025/26 is 88,000. If your taxable turnover drops below this level and you expect it to stay below, you can apply to deregister. Deregistration is not automatic, and you should consider the implications carefully. You will lose the ability to reclaim input VAT, and you may need to account for VAT on assets still held at deregistration. HMRC treats the assets as if you had sold them to yourself, and you must pay VAT on their current market value (unless the VAT due is less than 1,000).

VAT Rates

The UK has three VAT rates plus two categories that effectively have no VAT charge. Knowing which rate applies to each of your products or services is fundamental, because charging the wrong rate means either overcharging your customers or underpaying HMRC, both of which create problems.

RatePercentageExamples
Standard rate20%Most goods and services, consultancy, software, electronics
Reduced rate5%Domestic fuel and power, children's car seats, smoking cessation products
Zero rate0%Food (most), children's clothing, books and newspapers, exports
ExemptN/AInsurance, financial services, education, health services
Outside the scopeN/AWages, dividends, donations, statutory fees

Standard Rate (20%)

The standard rate of 20% applies to the majority of goods and services sold in the UK. If you are a consultant, developer, designer, or provide most types of professional services, all of your sales will be standard-rated. Most physical goods (electronics, furniture, clothing for adults) are also standard-rated.

When in doubt, the standard rate is the default. Only apply a different rate if you are certain your supply qualifies. HMRC publishes detailed guidance on which supplies qualify for reduced, zero, or exempt treatment.

Reduced Rate (5%)

The reduced rate of 5% applies to a limited number of supplies. The most common are domestic fuel and power (gas and electricity for homes), installation of energy-saving materials in residential properties, children's car seats, and certain contraceptive products. Most small businesses will rarely encounter the reduced rate in their own sales, though you may pay it on your business energy bills.

Zero Rate (0%)

Zero-rated supplies are technically taxable at 0%. This is an important distinction from exempt supplies because zero-rated businesses can still reclaim input VAT on their purchases. The main zero-rated categories are:

  • Food and drink: Most basic food items are zero-rated (bread, milk, fruit, vegetables, meat, fish). However, catering, hot takeaway food, confectionery, crisps, ice cream, and alcoholic drinks are standard-rated. The boundaries can be surprisingly specific.
  • Children's clothing and footwear: Items designed for children under 14 years old.
  • Books, newspapers, and e-publications: Both physical and digital publications qualify since 2020.
  • Exports: Goods exported outside the UK are zero-rated, provided you hold evidence of export.
  • New residential construction: The first sale of a newly built dwelling is zero-rated.

If your business makes zero-rated supplies, registration is almost always beneficial because you can reclaim input VAT on purchases while not adding VAT to your selling prices.

Exempt Supplies

Exempt supplies are not taxable for VAT purposes. You do not charge VAT on them, and crucially, you cannot reclaim input VAT on costs related to making exempt supplies. The main exempt categories are:

  • Insurance
  • Financial services (lending, dealing in securities)
  • Education and training (by eligible bodies)
  • Health and welfare services
  • Postal services (Royal Mail universal services)
  • Burial and cremation services
  • Some property transactions (rent on commercial property, unless you opt to tax)

If your business makes a mix of taxable and exempt supplies, you will need to deal with partial exemption rules when reclaiming input VAT. This is covered in the Input VAT & Output VAT section below.

Working Out Which Rate Applies

Determining the correct VAT rate requires understanding exactly what you are supplying and to whom. HMRC's VAT notices (available on gov.uk) provide definitive guidance for each sector. If your supply is a bundle of goods and services at different rates, you may need to apportion the price across the components, unless one element is clearly incidental to the other.

When you are uncertain, it is worth checking HMRC's published guidance or seeking professional advice. Charging the wrong rate is a common error that can be expensive to correct retrospectively.

VAT Schemes

HMRC offers several VAT accounting schemes designed to simplify administration for smaller businesses. Choosing the right scheme can save you time, improve cash flow, and in some cases reduce your VAT bill. Here is a detailed comparison of each option.

Standard VAT Accounting

Under standard accounting, you calculate the VAT you owe by taking the total output VAT on your sales and subtracting the total input VAT on your purchases. The tax point (the date VAT becomes due) is the earlier of the date you issue an invoice or the date you receive payment. This means you may owe VAT on invoices your clients have not yet paid.

Standard accounting gives you the most accurate VAT position and allows you to reclaim all eligible input VAT. It is suitable for businesses with straightforward transactions, good cash flow, and clients who pay promptly. Most businesses with turnover above the Flat Rate Scheme limit use standard accounting.

Flat Rate Scheme (FRS)

The Flat Rate Scheme lets you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC instead of calculating the actual difference between output and input VAT. You still charge customers the standard 20% VAT, but you keep the difference between what you charge and what you pay HMRC under the flat rate.

Eligibility: Your VAT-exclusive turnover must be 150,000 or less to join. You must leave if your total business income exceeds 230,000 (including VAT).

First-year discount: In your first year of VAT registration, you receive a 1% discount on your flat rate percentage.

Limited cost trader rule: If your expenditure on goods (not services) is less than 2% of your VAT-inclusive turnover, or less than 1,000 per year, you are classified as a limited cost trader and must use a flat rate of 16.5%. This rule was introduced in 2017 and significantly reduced the benefit of the FRS for most service-based businesses.

Business TypeFlat Rate %
Computer and IT consultancy or data processing14.5%
Management consultancy14%
Advertising11%
Architect, civil and structural engineer or surveyor14.5%
Accountancy or bookkeeping14.5%
Photography11%
Publishing11%
Real estate activity (not including property development)14%
Catering services including restaurants and takeaways12.5%
Retailing that is not listed elsewhere7.5%
Limited cost trader (any sector)16.5%

FRS Worked Example

Suppose you are an IT consultant with a flat rate of 14.5%. In a quarter, you invoice clients 30,000 + VAT = 36,000 (including 6,000 VAT). Under standard accounting, if you had 1,200 of input VAT on expenses, you would pay HMRC 6,000 - 1,200 = 4,800. Under the FRS, you pay 14.5% of 36,000 = 5,220. In this case, standard accounting saves you 420.

However, if you have very few expenses (common for consultants working from home), the FRS can sometimes work out cheaper in the first year with the 1% discount (13.5% rate). Run the comparison with your actual numbers before committing.

Cash Accounting Scheme

Under cash accounting, you only account for VAT when you receive payment from customers or make payment to suppliers, rather than when invoices are issued. This can significantly improve cash flow if you have clients who pay slowly, because you do not owe HMRC VAT on invoices that have not been paid.

Eligibility: Your estimated VAT-taxable turnover must be 1,350,000 or less. You must leave the scheme if your turnover exceeds 1,600,000.

Pros: Better cash flow, automatic bad debt relief (if a client never pays, you never owe the VAT).

Cons: You also cannot reclaim input VAT until you pay your suppliers, which can delay reclaims. Record-keeping must track both invoice dates and payment dates.

Annual Accounting Scheme

The Annual Accounting Scheme lets you submit just one VAT return per year instead of four. You make interim payments (typically 9 monthly payments or 3 quarterly payments) based on your estimated VAT liability, then submit a final return to settle any remaining balance.

Eligibility: Your estimated VAT-taxable turnover must be 1,350,000 or less. You must leave if your turnover exceeds 1,600,000.

Pros: Less paperwork (one return vs four), predictable payments, more time to file your annual return (2 months after your year end vs 1 month and 7 days for quarterly returns).

Cons: If you typically receive VAT refunds (common for zero-rated businesses), this scheme delays your refund to once a year. Interim payments are based on the previous year, so if your turnover drops significantly, you may overpay during the year.

Combining Schemes

You can combine some schemes. Cash accounting can be used alongside the Annual Accounting Scheme. However, you cannot use the Flat Rate Scheme with cash accounting on standard accounting calculations (though the FRS has its own cash-based variant built in).

VAT Returns

A VAT return tells HMRC how much VAT you have charged on your sales and how much VAT you have paid on your purchases during a specific period. Most businesses file quarterly, though the Annual Accounting Scheme allows annual filing. The return itself is a standardised form with 9 boxes, each serving a specific purpose.

The 9 Boxes Explained

Every VAT return contains the same 9 boxes. Understanding what goes in each box is essential for accurate filing:

BoxDescriptionWhat to Include
Box 1VAT due on sales and other outputsTotal VAT charged on your sales for the period
Box 2VAT due on acquisitions from EUVAT on goods acquired in Northern Ireland from EU states
Box 3Total VAT dueSum of Box 1 + Box 2 (calculated automatically)
Box 4VAT reclaimed on purchases and inputsTotal input VAT on business purchases you can reclaim
Box 5Net VAT to pay or reclaimBox 3 minus Box 4. Positive = you owe HMRC. Negative = refund due.
Box 6Total value of sales (ex VAT)Net value of all outputs excluding VAT
Box 7Total value of purchases (ex VAT)Net value of all inputs excluding VAT
Box 8Total value of supplies to EUGoods supplied from Northern Ireland to EU (ex VAT)
Box 9Total value of acquisitions from EUGoods acquired in Northern Ireland from EU (ex VAT)

Note on Boxes 2, 8, and 9: Since Brexit, these boxes are primarily relevant for businesses operating in Northern Ireland under the Windsor Framework. For businesses operating solely in Great Britain, these boxes will typically be zero.

Filing Deadlines

Under quarterly filing, your VAT return and payment are due 1 month and 7 days after the end of each VAT quarter. The common quarterly patterns and their deadlines are:

Quarter EndsReturn & Payment Due
31 March / 30 June / 30 September / 31 December7 May / 7 August / 7 November / 7 February
30 April / 31 July / 31 October / 31 January7 June / 7 September / 7 December / 7 March
31 May / 31 August / 30 November / 28/29 February7 July / 7 October / 7 January / 7 April

The New Penalty Points System

From January 2023, HMRC replaced the previous default surcharge regime with a points-based penalty system. Here is how it works:

  • Each late submission earns you 1 penalty point
  • Once you reach the penalty points threshold (4 points for quarterly filers, 2 for monthly, 2 for annual), you receive a 200 penalty for that late submission and every subsequent late submission
  • Points expire after a period of compliance: for quarterly filers, you must submit 4 consecutive returns on time, and your points reset to zero

Late Payment Interest and Penalties

Separately from the submission penalty, there are penalties for late payment of VAT:

  • Up to 15 days late: No penalty (but interest accrues from day 1)
  • 16 to 30 days late: 2% penalty on the VAT outstanding at day 15
  • 31+ days late: 2% penalty on VAT outstanding at day 15, plus 2% on VAT outstanding at day 30, plus a daily penalty of 4% per annum on the remaining balance

HMRC also charges interest on late payments at the Bank of England base rate plus 2.5%. Conversely, if HMRC owes you a repayment and it is late, they pay you interest at the base rate minus 1% (minimum 0.5%).

Payment Methods

You can pay your VAT bill by Direct Debit (set up through your Government Gateway account), online banking (Faster Payments or BACS), CHAPS, or by debit or corporate credit card. Direct Debit is the most popular method because it collects payment automatically 3 working days after the deadline, giving you the maximum time to pay without risk of missing the date.

Making Tax Digital

Making Tax Digital (MTD) for VAT is HMRC's programme to modernise the UK tax system by requiring businesses to keep digital records and submit tax returns through compatible software. MTD for VAT has been fully in force since April 2022 for all VAT-registered businesses, regardless of turnover.

What MTD Requires

There are three core requirements under MTD for VAT:

  1. Digital record-keeping: You must keep your VAT records digitally. This means using software rather than paper records or manual spreadsheets. The records must include your business name and address, VAT registration number, details of each supply you make and receive, the rate of VAT, the time of supply (tax point), and the net value excluding VAT.
  2. Digital submission: You must submit your VAT return using MTD-compatible software that connects directly to HMRC's systems via their API. You can no longer submit through HMRC's online VAT portal.
  3. Digital links: There must be a digital link between your source records and your VAT return. This means no manual re-keying of data. If you use a spreadsheet to capture initial data, there must be an automated transfer (digital link) from that spreadsheet to your filing software.

Compatible Software

HMRC maintains a list of MTD-compatible software on gov.uk. Options range from full accounting packages to bridging software that connects spreadsheets to HMRC. The main categories are:

  • Full accounting software: Cloud-based platforms like AccountsOS, Xero, QuickBooks, FreeAgent, and Sage handle all your bookkeeping and file directly with HMRC. This is the simplest approach for most businesses.
  • Bridging software: If you prefer to maintain your records in a spreadsheet, bridging software lets you submit your return from the spreadsheet while maintaining the digital link. This can work but adds complexity.
  • HMRC's free tool: HMRC offers a free MTD-compatible tool for the simplest cases, but it has limited features and is not suitable for most businesses.

Penalties for Non-Compliance

Failing to comply with MTD requirements carries its own set of penalties. If HMRC determines that you have not kept adequate digital records or have not used compatible software, they can issue penalties of up to 400 per offence. In practice, HMRC has been relatively lenient during the transition period, but enforcement is tightening. The safest approach is to use proper accounting software from the start.

MTD for Income Tax (Coming Soon)

MTD is expanding beyond VAT. From April 2026, Making Tax Digital for Income Tax Self Assessment (MTD ITSA) will apply to self-employed individuals and landlords with income over 50,000. This will be extended to those with income over 30,000 from April 2027. While this does not directly affect VAT, it signals HMRC's broader direction toward fully digital tax administration. Getting your digital record-keeping in order now for VAT will make the transition smoother when MTD extends further.

For a practical walkthrough of what you need to do, see our MTD compliance checklist and our guide to Making Tax Digital changes in 2026.

Input VAT & Output VAT

The mechanics of VAT revolve around two concepts: output VAT (the VAT you charge on your sales) and input VAT (the VAT you pay on your business purchases). Your VAT return is fundamentally a calculation of output VAT minus input VAT. When output exceeds input, you pay the difference to HMRC. When input exceeds output (common for businesses with zero-rated sales or periods of heavy investment), HMRC refunds the difference to you.

Reclaiming Input VAT

You can reclaim VAT on any purchase that is made for business purposes and supported by a valid VAT invoice. The invoice must show the supplier's VAT number, the date, a description of the goods or services, the VAT rate, and the VAT amount. For purchases under 250 (including VAT), a simplified invoice (such as a till receipt from a VAT-registered retailer) is sufficient.

Common input VAT claims include:

  • Office supplies and equipment
  • Software subscriptions and cloud services
  • Professional fees (accountant, lawyer, consultant)
  • Marketing and advertising costs
  • Business travel (trains, flights, hotels)
  • Vehicle expenses (fuel, maintenance, if the vehicle is used for business)
  • Telephone and internet costs (business proportion)
  • Stock and materials

Blocked Input VAT

Some categories of input VAT cannot be reclaimed regardless of business use. The main blocked categories are:

  • Business entertaining: You cannot reclaim VAT on entertaining clients, prospects, or other non-employees. This includes meals, drinks, event tickets, and hospitality. Staff entertaining (such as a Christmas party for employees) is reclaimable, provided it is available to all staff.
  • Cars: VAT on the purchase of a car cannot generally be reclaimed unless the car is used exclusively for business (no private use at all), used as a taxi, a driving school car, or for hire. In practice, most directors with any private use cannot reclaim the VAT on a car purchase. VAT on leasing a car is 50% reclaimable if there is some private use.
  • Non-business purchases: Any purchase not used for business purposes. If an item has mixed use (business and personal), you can only reclaim the business proportion.

Partial Exemption

If your business makes both taxable supplies (standard, reduced, or zero-rated) and exempt supplies, you are partially exempt. This means you cannot reclaim all your input VAT. You must apportion your input VAT between taxable and exempt activities.

The standard method for partial exemption is to:

  1. Directly attribute input VAT to taxable supplies (fully reclaimable) or exempt supplies (not reclaimable) where possible
  2. For residual input VAT that cannot be directly attributed (general overheads like rent, utilities, accounting fees), apportion based on the ratio of taxable supplies to total supplies

There is a de minimis rule: if your exempt input VAT is both under 625 per month on average AND less than 50% of your total input VAT, you can treat it as fully reclaimable. This simplifies matters for businesses where exempt income is a small part of the picture.

Capital Goods Scheme

The Capital Goods Scheme (CGS) applies to high-value capital assets: land and buildings (or parts thereof) with a value of 250,000 or more (excluding VAT), and computers and computer equipment with a value of 50,000 or more (excluding VAT). Under the CGS, the initial input VAT recovery is adjusted over a period of years (10 years for land and buildings, 5 years for computers) to reflect changes in the proportion of taxable use.

This is most relevant if you purchase commercial property and your use of that property changes between taxable and exempt activities over the adjustment period. For most small businesses, the CGS rarely applies, but it is worth being aware of if you are planning significant capital expenditure.

Pre-Registration Input VAT

When you first register for VAT, you can reclaim input VAT on eligible purchases made before your registration date:

  • Goods: VAT on goods purchased up to 4 years before your effective date of registration, provided the goods are still on hand (or were used to make goods still on hand) at the date of registration
  • Services: VAT on services purchased up to 6 months before your registration date, provided they were supplied for business purposes

This can provide a valuable one-off reclaim, particularly for businesses that purchased equipment, stock, or received professional services during their startup phase.

VAT on Specific Transactions

While most domestic sales of goods and services follow straightforward VAT rules, several transaction types have special treatment. Understanding these is essential if your business trades internationally, deals in property, provides digital services, or handles mixed supplies.

International Trade Post-Brexit

Since 1 January 2021, the UK is no longer part of the EU VAT area (with the exception of Northern Ireland for goods under the Windsor Framework). This has significantly changed how VAT applies to cross-border transactions.

Exporting goods: Goods exported from the UK to any country (including EU member states) are zero-rated. You do not charge VAT, but you must hold evidence of export (shipping documentation, customs declarations, proof of delivery abroad). Without this evidence, HMRC may treat the supply as a domestic sale and require you to account for VAT at 20%.

Importing goods: When you import goods into the UK, you must account for import VAT. Since January 2021, postponed VAT accounting (PVA) allows you to account for and recover import VAT on the same VAT return, rather than paying it at the border and reclaiming it later. This eliminates the cash flow impact of import VAT.

Services to overseas businesses: Under the general place of supply rule for B2B services, the supply takes place where the customer belongs. If you supply services to a business in another country, the supply is generally outside the scope of UK VAT. The customer accounts for VAT under the reverse charge in their own country. You still need to include the value in Box 6 of your VAT return.

Services to overseas consumers: The rules for B2C services vary by service type. For most services, the place of supply is where you (the supplier) belong, so UK VAT applies. However, certain services (notably digital services, telecoms, and broadcasting) are supplied where the consumer is located. If you supply digital services to consumers in the EU, you may need to register for the EU One Stop Shop (OSS) scheme.

Reverse Charge

The reverse charge shifts the obligation to account for VAT from the supplier to the customer. In the UK, the reverse charge applies in two main scenarios:

  • Services received from abroad: If you receive services from a supplier in another country that would be taxable in the UK, you must apply the reverse charge. You account for both the output VAT (as if you had supplied the service to yourself) and the input VAT (which you can reclaim if the service is used for taxable business purposes). The net effect is typically neutral, but you must include the amounts on your VAT return.
  • Domestic reverse charge for construction: Since March 2021, the domestic reverse charge applies to construction services reported under the Construction Industry Scheme (CIS). If your business provides or receives construction services within CIS, the customer (rather than the supplier) accounts for the VAT. This was introduced to combat fraud in the construction supply chain.

Digital Services

If you sell digital services (software, digital downloads, streaming, online courses, e-books) to consumers outside the UK, special rules apply. For consumers in the EU, you should register for the EU One Stop Shop (OSS) scheme, which allows you to submit a single quarterly return for all EU consumer sales rather than registering for VAT in each EU country. For consumers in the rest of the world, the service is generally outside the scope of UK VAT. For B2B digital services, the reverse charge applies as described above.

Property and Land

Property transactions have some of the most complex VAT rules. The key points for small business owners are:

  • Residential property: The sale of new residential buildings (within 3 years of completion) is zero-rated. The sale of existing residential buildings is exempt. Residential rents are exempt.
  • Commercial property: The sale and rent of commercial property is exempt by default. However, the property owner can choose to "opt to tax" the property, which makes the sale or rent standard-rated. This is advantageous if the owner wants to reclaim input VAT on construction, renovation, or running costs. If a landlord has opted to tax, you will pay VAT on your rent.
  • Transfer of a Going Concern (TOGC): If you buy or sell a business (or part of a business) as a going concern, the transfer is outside the scope of VAT. This can save significant amounts on business and property transactions, but strict conditions must be met.

Mixed and Composite Supplies

Sometimes a single transaction includes elements that would attract different VAT rates if sold separately. HMRC distinguishes between:

  • Composite supply: One supply consisting of several elements, where one element is dominant. The whole supply takes the VAT rate of the dominant element. For example, a restaurant meal (food plus service) is a single composite supply at the standard rate.
  • Mixed supply: Multiple separate supplies bundled together but each capable of being supplied independently. Each element is taxed at its own rate. For example, a hamper containing zero-rated food and standard- rated wine is a mixed supply, and the price must be apportioned.

Getting this distinction right is important. If you offer bundled products or services at different VAT rates, seek advice on whether HMRC would treat them as composite or mixed.

Common VAT Mistakes

VAT errors are among the most common reasons HMRC opens enquiries into small businesses. Most of these mistakes are avoidable with proper systems and awareness. Here are the 10 errors we see most frequently.

1. Registering Late for VAT

The most expensive VAT mistake is failing to monitor your rolling 12-month turnover and registering late. When HMRC backdates your registration, you owe VAT on all sales from the date you should have registered. If you cannot recover this from your clients (and in many cases you cannot), the VAT comes directly from your profits. The penalty for late registration ranges from 5% to 15% of the VAT owed, on top of the VAT itself. Set a monthly reminder to check your rolling turnover against the 90,000 threshold.

2. Applying the Wrong VAT Rate

Charging 20% on a zero-rated supply means your customer overpays, and you owe HMRC more than you should. Charging 0% on a standard-rated supply means you owe HMRC money you did not collect. Both scenarios create problems during an HMRC review. If you are unsure about the correct rate for your specific goods or services, check HMRC's VAT notices or seek professional advice before you start trading.

3. Not Keeping Valid VAT Invoices

You can only reclaim input VAT if you hold a valid VAT invoice. A receipt showing the total paid is not sufficient, it must include the supplier's VAT number, the date, a description, the VAT amount, and the net amount. Without a valid invoice, HMRC can disallow your input VAT claim. Train yourself to check every invoice you receive for these details.

4. Claiming VAT on Business Entertaining

Many businesses claim input VAT on client lunches, event hospitality, or gifts to clients. This is blocked input VAT and cannot be reclaimed regardless of how genuine the business purpose. Staff entertaining (Christmas parties, team events) is reclaimable, but client entertaining is not. The distinction trips up many small business owners.

5. Missing Quarterly Deadlines

With the new penalty points system, every late submission accumulates a point. Quarterly filers who miss 4 deadlines within a rolling period trigger the 200 penalty, which then applies to every subsequent late submission until they submit 4 returns on time. Set calendar reminders for your VAT deadlines at least two weeks before they are due, and use Direct Debit to avoid late payment.

6. Forgetting to Account for the Reverse Charge

If you receive services from overseas suppliers or operate in the construction industry under CIS, the reverse charge may apply. Failing to account for it means your VAT return is incorrect. While the net effect is usually neutral (you account for output and input VAT simultaneously), the omission itself can trigger penalties and demonstrates poor record-keeping.

7. Not Using Postponed VAT Accounting for Imports

Since January 2021, you can use postponed VAT accounting (PVA) to account for import VAT on your VAT return rather than paying it at the border. If you are not using PVA, you are tying up cash unnecessarily. The import VAT you pay at the border is reclaimable, but there is a cash flow delay between payment and reclaim. PVA eliminates this entirely.

8. Mixing Up VAT Periods with Accounting Periods

Your VAT quarters do not have to match your company's accounting year, and they often do not. Confusing the two leads to errors in which transactions fall into which return. Each VAT return should include transactions based on their tax point (or payment date under cash accounting) within that specific VAT quarter, not based on your company year end.

9. Incorrect Treatment of Bad Debts

Under standard VAT accounting, if you have already accounted for output VAT on an invoice that your client never pays, you can reclaim the VAT as a bad debt relief claim. However, strict conditions apply: the debt must be at least 6 months old, written off in your accounts, and you must have already paid the VAT to HMRC. Many businesses either forget to make this claim or attempt to claim too early.

10. Choosing the Wrong VAT Scheme

Selecting a scheme without running the numbers can cost you money. The Flat Rate Scheme might seem simpler, but for limited cost traders at 16.5%, you almost certainly pay more than under standard accounting. Conversely, businesses with excellent cash flow may not benefit from cash accounting. Review your scheme choice annually with actual figures to confirm it still makes sense for your business.

Frequently Asked Questions

What is the VAT registration threshold for 2025/26?

The compulsory VAT registration threshold for 2025/26 is 90,000. You must register if your taxable turnover exceeds 90,000 in any rolling 12-month period, or if you expect it to exceed 90,000 in the next 30 days alone. The deregistration threshold is 88,000. These thresholds apply to taxable turnover, not total revenue, so exempt supplies are excluded from the calculation.

Should I voluntarily register for VAT below the threshold?

Voluntary registration can make sense if most of your clients are VAT-registered businesses (they reclaim the VAT you charge, so your prices are effectively the same), if you have significant VAT-able purchases to reclaim, or if you want to appear more established. It is less beneficial if you sell mainly to consumers who cannot reclaim VAT, as it effectively increases your prices by 20%. Run the numbers for your specific situation before deciding.

How does the Flat Rate Scheme work and is it worth it?

Under the Flat Rate Scheme you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC instead of calculating the difference between output and input VAT. The percentage varies by industry, typically between 9.5% and 16.5%. You still charge clients 20% VAT but keep the difference between what you charge and what you pay HMRC. However, limited cost traders (goods purchases less than 2% of turnover or under 1,000 per year) must use the 16.5% rate, which usually makes the scheme unattractive for service businesses with few physical goods.

What happens if I register late for VAT?

If you should have registered but did not, HMRC will backdate your registration to when you should have registered. You will owe VAT on all taxable sales from that date, even if you did not charge your clients VAT. You may also receive a late registration penalty based on the VAT you owe and how late you are. The penalty ranges from 5% to 15% of the VAT due. Monitor your rolling 12-month turnover monthly to avoid this situation.

How often do I need to submit VAT returns?

Most businesses submit VAT returns quarterly. Your VAT quarters are set when you register and do not have to align with your accounting year. Each return covers three months and is due, along with payment, 1 month and 7 days after the end of the quarter. If you use the Annual Accounting Scheme, you submit one return per year and make interim payments. Regardless of the scheme, all returns must be filed digitally through MTD-compatible software.

Can I reclaim VAT on expenses before I was VAT registered?

Yes, with limits. You can reclaim VAT on goods purchased up to 4 years before your registration date, provided the goods are still on hand at the date of registration and were bought for business use. For services, you can reclaim VAT on services purchased up to 6 months before registration. Keep the original VAT invoices as evidence. This is particularly useful for reclaiming VAT on equipment, stock, or professional fees incurred during your startup phase.

What records do I need to keep for VAT?

You must keep digital records of all sales and purchases including the VAT charged, your business name, address, and VAT registration number, the VAT rate applied to each transaction, the time of supply (tax point), and the net value excluding VAT. Records must be kept for at least 6 years. Under Making Tax Digital, these records must be maintained digitally with digital links between your records and your VAT return, meaning no manual re-keying of figures.

Do I charge VAT on sales to customers in the EU after Brexit?

For goods exported to the EU, these are now zero-rated exports (0% VAT). You must hold evidence of export such as shipping documentation. For services supplied to EU businesses, the general rule is that they are outside the scope of UK VAT under the place of supply rules, and the EU customer accounts for VAT under the reverse charge. For services to EU consumers, the rules depend on the type of service. Digital services to EU consumers may require registration under the EU One Stop Shop (OSS) scheme.
