UK VAT Guide: Registration, Rates, and Returns

Value Added Tax (VAT) is a consumption tax charged on most goods and services sold in the United Kingdom. It is collected by VAT-registered businesses on behalf of HM Revenue and Customs (HMRC) at each stage of the supply chain, with the end consumer bearing the final cost. For businesses, VAT is not a cost in most cases -- it is collected on sales (output tax) and reclaimed on purchases (input tax), with only the net difference paid to or reclaimed from HMRC.

Understanding how VAT works is essential for any company operating in the UK. This guide covers the current VAT rates, when and how to register, Making Tax Digital requirements, how to complete and submit VAT returns, the flat rate scheme, VAT groups, input tax recovery rules, and the practical steps required to stay compliant. Whether you are forming a new UK company or reviewing the obligations of an existing business, this guide provides the detail you need.

UK VAT Rates

The UK operates three main VAT rates, plus an exemption category.

VAT Rate	Percentage	Applies To
Standard rate	20%	Most goods and services
Reduced rate	5%	Domestic fuel and power, children's car seats, certain energy-saving installations, smoking cessation products, contraceptives
Zero rate	0%	Most food (not catering or hot takeaway), children's clothing and footwear, books, newspapers, public transport, new residential construction, exports
Exempt	N/A	Financial services, insurance, education, health services, burial and cremation, postal services, certain property transactions

The distinction between zero-rated and exempt supplies is important. Zero-rated supplies are still taxable supplies -- they are simply taxed at 0%. A business making zero-rated supplies is still entitled to register for VAT and reclaim input tax on its purchases. A business making only exempt supplies cannot register for VAT (unless it also makes taxable supplies) and cannot reclaim input tax.

The correct VAT rate for a product or service is not always obvious. For example, a plain biscuit is zero-rated, but a chocolate-covered biscuit is standard-rated. A cold takeaway sandwich is zero-rated, but a hot takeaway is standard-rated. Getting the rate wrong exposes your business to assessments, interest, and penalties from HMRC. When in doubt, check HMRC's VAT notices or seek professional advice before charging or not charging VAT on a supply.

VAT Registration

Mandatory Registration

You must register for VAT if:

Your taxable turnover in the previous 12 months (on a rolling basis, not by calendar or financial year) exceeds the registration threshold of 90,000 GBP
You expect your taxable turnover to exceed 90,000 GBP in the next 30 days alone

Taxable turnover includes all standard-rated, reduced-rated, and zero-rated supplies. It does not include exempt supplies or supplies made outside the UK.

When the threshold is breached, you must notify HMRC within 30 days. HMRC will then register you from the first day of the second month after the threshold was exceeded. Late notification can result in being registered from the date you should have been registered, with VAT owing on all taxable supplies made since that date.

Voluntary Registration

You can register for VAT voluntarily even if your turnover is below the threshold. Voluntary registration allows you to:

Reclaim VAT on business purchases (input tax)
Appear larger and more established to customers and suppliers
Reclaim VAT incurred before registration on goods still held (up to 4 years) and services (up to 6 months)

The disadvantage is that you must charge VAT on your sales, which may make your prices less competitive if your customers are not VAT-registered (since they cannot reclaim the VAT you charge). For B2B businesses, voluntary registration is almost always beneficial. For B2C businesses selling to consumers, the calculation is more nuanced.

Deregistration

You can deregister for VAT if your taxable turnover falls below the deregistration threshold of 88,000 GBP, or if you stop making taxable supplies altogether. When deregistering, you must account for VAT on any business assets worth 1,000 GBP or more that you retain.

If you are a new business and expect to grow past the VAT threshold within your first year, consider registering voluntarily from the start. This avoids the administrative disruption of mid-year registration and allows you to reclaim input tax on your startup costs. Many businesses find that VAT registration adds credibility when dealing with other VAT-registered businesses and that the input tax recovery more than offsets the administrative burden.

The Registration Process

VAT registration is completed online through the HMRC website. You will need:

Your company's Unique Taxpayer Reference (UTR) or Companies House number
Details of the business activities (SIC codes)
Bank account details for VAT repayments
Estimated taxable turnover for the next 12 months
The date you need to be registered from

HMRC typically processes VAT registrations within 30 working days, though it can take longer. Upon registration, you receive a VAT registration certificate showing your VAT number, which you must display on all VAT invoices.

Making Tax Digital (MTD) for VAT

Since April 2022, all VAT-registered businesses, regardless of turnover, must comply with Making Tax Digital requirements. MTD requires:

Digital record-keeping: All VAT records must be kept digitally using MTD-compatible software. This includes records of supplies made and received, VAT charged and reclaimed, and adjustments.
Digital submission: VAT returns must be submitted directly from MTD-compatible software via an API connection to HMRC. You can no longer file returns through the HMRC online portal.
Digital links: If you use multiple software programs or spreadsheets as part of your record-keeping, the data must flow between them via digital links. Manual re-keying or copy-pasting of figures is not permitted.

HMRC maintains a list of MTD-compatible software. Popular options include Xero, QuickBooks, Sage, and FreeAgent. Many of these offer free or low-cost tiers suitable for small businesses.

VAT Returns

Filing Frequency

Most businesses file VAT returns quarterly. Each VAT return covers a three-month period, and there are four returns per year. HMRC assigns your quarterly periods (known as "stagger groups") when you register. The three stagger groups are:

January, April, July, October (returns due by the 7th of the following month, or 7 calendar days later for MTD)
February, May, August, November
March, June, September, December

You can request a change to a different stagger group or apply for monthly returns if your business regularly reclaims more VAT than it pays (which generates repayments from HMRC). Annual accounting is also available for businesses with turnover under 1,350,000 GBP.

Filing Deadline and Payment

VAT returns and payments are due one calendar month and 7 days after the end of each VAT period. For example, a VAT return for the period ending 31 March 2026 is due by 7 May 2026.

Payment can be made by direct debit (which gives an additional 3 working days), bank transfer, or corporate credit/debit card. Direct debit is the most common method and is recommended to avoid missed deadlines.

What the VAT Return Contains

The VAT return consists of nine boxes:

Box	Description
Box 1	VAT due on sales and other outputs
Box 2	VAT due on acquisitions from EU member states (if applicable under the Windsor Framework)
Box 3	Total VAT due (Box 1 + Box 2)
Box 4	VAT reclaimed on purchases and other inputs
Box 5	Net VAT to pay or reclaim (Box 3 - Box 4)
Box 6	Total value of sales and other outputs (excluding VAT)
Box 7	Total value of purchases and other inputs (excluding VAT)
Box 8	Total value of supplies to EU member states (if applicable)
Box 9	Total value of acquisitions from EU member states (if applicable)

Box 5 is the key figure. If positive, you owe HMRC. If negative, HMRC owes you a repayment.

Input Tax Recovery

VAT-registered businesses can reclaim input tax -- the VAT they are charged on business purchases. However, there are important rules and restrictions.

Requirements for Claiming Input Tax

To claim input tax, you must:

Hold a valid VAT invoice for the purchase (or a simplified invoice for purchases under 250 GBP)
The purchase must be for business purposes
The supply must not fall within a category of blocked input tax

Blocked Input Tax

Certain categories of expenditure are blocked from input tax recovery regardless of their business use:

Business entertainment (unless for overseas customers)
Motor cars (unless used exclusively for business, such as by a taxi company or driving school)
Non-business use proportion of goods or services with mixed use

Partial Exemption

If your business makes both taxable and exempt supplies, you are partially exempt and can only recover input tax that relates to taxable supplies. Input tax that relates to exempt supplies is not recoverable. Input tax that cannot be directly attributed to either taxable or exempt supplies must be apportioned using a partial exemption method (the standard method is based on the ratio of taxable to total supplies).

There is a de minimis threshold: if your exempt input tax is less than 625 GBP per month on average and less than 50% of total input tax, you can recover it in full.

Partial exemption calculations are among the most complex areas of UK VAT. Businesses in sectors like financial services, property, and education frequently encounter partial exemption issues. If your business makes a mix of taxable and exempt supplies, it is worth investing in specialist VAT advice to ensure you are recovering the maximum permissible input tax and applying the most advantageous partial exemption method.

The VAT Flat Rate Scheme

The Flat Rate Scheme (FRS) is designed to simplify VAT accounting for small businesses. Instead of calculating VAT on each individual transaction, you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC.

Eligibility

VAT-taxable turnover must be 150,000 GBP or less (excluding VAT) to join
You must leave the scheme if your total business income exceeds 230,000 GBP (including VAT) in any 12-month period

How It Works

HMRC publishes flat rate percentages for different business sectors. For example:

Computer and IT consultancy: 14.5%
Management consultancy: 14%
Retailing food, confectionery, tobacco, newspapers, or children's clothing: 4%
Accountancy or bookkeeping: 14.5%
Advertising: 11%

You charge customers VAT at the standard 20% rate as normal, but instead of paying the difference between output and input tax, you pay the flat rate percentage of your gross turnover. You cannot reclaim input tax on purchases (except for capital assets costing 2,000 GBP or more including VAT).

In the first year of VAT registration, you receive a 1% discount on the flat rate percentage.

Limited Cost Trader Rules

If your VAT-inclusive expenditure on goods is less than 2% of your VAT-inclusive turnover, or less than 1,000 GBP per year (if your turnover is over 50,000 GBP), you are classified as a "limited cost trader" and must use a flat rate of 16.5% regardless of your sector. This rule was introduced to prevent businesses with low costs (such as labour-only contractors) from gaining a windfall benefit from the scheme.

Is the Flat Rate Scheme Worth It?

The FRS saves time and administrative effort but does not always save money. It tends to benefit businesses that:

Have relatively low input VAT (e.g., service businesses with few purchases)
Are in sectors with lower flat rate percentages
Value simplicity over optimisation

Businesses with significant purchases that attract VAT (e.g., retailers buying stock) may be better off on the standard scheme where they can reclaim input tax in full.

VAT Groups

Two or more corporate bodies under common control can apply to form a VAT group. When a VAT group is formed:

The group is treated as a single taxable person for VAT purposes
Supplies between group members are disregarded for VAT (no VAT is charged on intra-group transactions)
One member (the representative member) submits a single VAT return covering the entire group
All members are jointly and severally liable for the group's VAT debts

VAT grouping can simplify administration and improve cash flow where companies within a group make significant supplies to each other. It is also beneficial where one group member makes exempt supplies -- the exemption applies to external supplies only, and the internal supplies that would otherwise be exempt (and block input tax recovery) are simply disregarded.

To form a VAT group, each member must be a body corporate (companies, LLPs, etc.) established or with a fixed establishment in the UK, and they must be under common control. Sole traders and partnerships (other than LLPs) cannot be members of a VAT group.

VAT on International Trade

Exports

Exports of goods to customers outside the UK are zero-rated, provided you hold evidence of export (such as shipping documentation). Exports of services depend on the place-of-supply rules, which vary by the type of service.

Imports

Goods imported into the UK are subject to import VAT at the point of entry. Since 1 January 2021, businesses can use Postponed VAT Accounting (PVA) to account for import VAT on their VAT return rather than paying it at the border. This eliminates the cash flow disadvantage of paying import VAT upfront and waiting to reclaim it.

The Windsor Framework and Northern Ireland

Northern Ireland has a unique position under the Windsor Framework (formerly the Northern Ireland Protocol). For goods, Northern Ireland effectively remains within the EU VAT system, meaning EU rules apply to the movement of goods between Northern Ireland and EU member states. For services, Northern Ireland follows UK VAT rules. This creates complexity for businesses operating across the UK internal border.

Common VAT Mistakes to Avoid

Failing to monitor the registration threshold: The 90,000 GBP threshold is assessed on a rolling 12-month basis, not on your financial year. Check your position regularly.
Applying the wrong VAT rate: As noted above, the correct rate is not always intuitive. Get it wrong and you face assessments plus interest.
Not keeping proper VAT invoices: Without valid invoices, HMRC can deny your input tax claims.
Missing the MTD requirements: Filing through the HMRC portal instead of MTD-compatible software can result in penalties.
Ignoring partial exemption: If you make any exempt supplies, you must consider the partial exemption rules.

VAT Penalties Under the Points-Based System

Since January 2023, HMRC has operated a points-based penalty system for late VAT returns and a separate regime for late payments.

For late submissions, you receive a penalty point for each late return. When you reach the penalty threshold (4 points for quarterly returns), you receive a 200 GBP penalty for that return and each subsequent late return until you bring your compliance up to date.

For late payments, penalties are calculated as a percentage of the outstanding VAT:

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

Interest on late payments is charged at the Bank of England base rate plus 2.5%.

VAT and Your Corporation Tax

VAT and corporation tax interact in several ways. If your business is VAT-registered, most VAT is neutral -- you collect it on sales and reclaim it on purchases. However, irrecoverable input tax (such as blocked input tax or the non-deductible portion under partial exemption) is treated as part of the cost of the expense for corporation tax purposes.

If your business is not VAT-registered, all VAT on purchases is a cost that feeds into your corporation tax computation. This is one reason why understanding your corporation tax position alongside your VAT position is important for overall tax planning.

For owner-managed companies considering how to structure their remuneration, see our guide to tax-efficient salary and dividends, as the VAT position of a business can indirectly affect profit extraction strategies.

Businesses that are not required to register for VAT but choose not to register voluntarily should be aware that they are absorbing VAT on their costs without recovery. For a business spending 50,000 GBP per year on VAT-bearing expenses, this represents approximately 8,333 GBP in irrecoverable VAT. Voluntary registration may be worth considering even for businesses well below the threshold, particularly if their customers are VAT-registered and can reclaim any VAT charged to them.

Frequently Asked Questions

What is the UK VAT registration threshold in 2026?

The UK VAT registration threshold is 90,000 GBP. You must register for VAT if your taxable turnover in the previous 12 months exceeds 90,000 GBP, or if you expect it to exceed 90,000 GBP in the next 30 days. You can also register voluntarily even if your turnover is below the threshold.

What are the UK VAT rates?

The standard UK VAT rate is 20% and applies to most goods and services. The reduced rate of 5% applies to certain items including domestic fuel, children's car seats, and some energy-saving installations. The zero rate of 0% applies to most food, children's clothing, books, and newspapers. Some supplies are VAT exempt, meaning no VAT is charged and input tax may not be recoverable.

What is Making Tax Digital for VAT?

Making Tax Digital (MTD) is an HMRC requirement that all VAT-registered businesses must keep digital records and submit VAT returns using MTD-compatible software. Spreadsheets alone are no longer sufficient. You must use accounting software that can connect to HMRC systems via an API to file your returns digitally.

What is the VAT Flat Rate Scheme?

The VAT Flat Rate Scheme is a simplified scheme for businesses with VAT-taxable turnover of 150,000 GBP or less. Instead of calculating VAT on every transaction, you pay a fixed percentage of your gross turnover to HMRC based on your industry sector. You cannot reclaim VAT on purchases (except capital assets over 2,000 GBP). The scheme reduces administrative burden but may not save money for all businesses.
