VAT and Sales Tax in United Kingdom

Value Added Tax (VAT) is the United Kingdom's principal indirect tax on the supply of goods and services, governed by the Value Added Tax Act 1994. Businesses charge VAT to customers (output VAT), reclaim VAT paid on their own purchases (input VAT), and remit the difference to HM Revenue and Customs (HMRC) via quarterly returns. Understanding which rate applies -- and whether registration is required -- is one of the first practical questions for any UK business owner or self-employed person.

What VAT rates apply in the United Kingdom?

HMRC operates three positive rates and an exempt category [SC1]:

The distinction between zero-rated and exempt is legally significant. Zero-rated supplies are taxable supplies charged at 0%; a business making zero-rated supplies can still reclaim input VAT on its costs. Exempt supplies fall outside the VAT system; a business making exclusively exempt supplies cannot register for VAT and cannot recover input VAT. A business making both taxable (including zero-rated) and exempt supplies is partially exempt and must apportion input VAT under the partial exemption rules [SC1].

From 1 January 2025, private-school fees became subject to standard-rate VAT at 20%, ending their previous exempt status. This was a targeted policy change under the Finance Act 2024 and does not affect state-funded or most further-education institutions [SC2].

What is the VAT registration threshold and when must a business register?

A business must register for VAT with HMRC when its VAT-taxable turnover in any rolling 12-month period exceeds GBP 90,000. This threshold was raised from GBP 85,000 effective 1 April 2024, announced at Spring Budget 2024, and is the highest mandatory VAT registration threshold among all OECD member countries, equal only to Switzerland [SC3]. Mandatory registration also applies when a business reasonably expects to exceed the threshold within the next 30 days.

Voluntary registration is available for businesses below the threshold -- this is often worthwhile for B2B-focused businesses whose customers are themselves VAT-registered and can recover the VAT charged. The deregistration threshold sits at GBP 88,000; a registered business may apply to deregister when it expects taxable turnover to fall below this level.

Once registered, businesses charge output VAT on their taxable supplies and file quarterly VAT returns, remitting the difference between output VAT collected and input VAT reclaimed. The return and payment are due 30 days after the end of the VAT accounting period [SC1].

What is Making Tax Digital for VAT and who does it affect?

Making Tax Digital for VAT (MTD for VAT) has been mandatory for all VAT-registered businesses since April 2022, regardless of turnover, under powers in the Finance (No. 2) Act 2017 and the Value Added Tax (Amendment) Regulations 2018 [SC4]. MTD for VAT requires businesses to:

• Maintain VAT records in functional compatible software (or spreadsheets with bridging software connected via a digital link).
• Submit quarterly VAT returns directly to HMRC through the MTD API, not through the older online portal.
• Ensure all transfers of data between systems use digital links -- no manual re-keying of figures between steps in the bookkeeping chain.

HMRC automatically enrolls new VAT-registered businesses into MTD unless they have applied for an exemption (available for reasons such as disability, religious belief, or demonstrable incompatibility with digital filing). The government maintains a list of HMRC-recognised MTD-compatible software, including Xero, QuickBooks Online, Sage Business Cloud, FreeAgent, and bridging tools such as VitalTax and Easy MTD VAT.

The points-based late-submission penalty system introduced in January 2023 applies to MTD for VAT filers: each missed return adds one point, and a GBP 200 penalty applies once a business reaches the 4-point threshold for quarterly filers. Points reset after 24 consecutive months of full compliance [SC4].

How does the VAT Flat Rate Scheme work for small businesses?

The Flat Rate Scheme (FRS), governed by VAT Notice 733, is available to VAT-registered businesses with VAT-taxable turnover of GBP 150,000 or less (excluding VAT) [SC5]. Under FRS, instead of tracking output and input VAT on individual transactions, the business:

1. Charges customers at the normal VAT rate (20% for standard-rated supplies).
2. Pays HMRC a fixed flat rate percentage applied to gross (VAT-inclusive) turnover -- the percentage depends on the business sector, ranging from approximately 4% for food retailers to 14.5% for accountancy or financial services.
3. Keeps the difference between the 20% charged to customers and the flat rate paid to HMRC.
4. Cannot reclaim input VAT on purchases, except for certain capital assets costing more than GBP 2,000.

A 1% discount applies during the first year of VAT registration, reducing the sector flat rate by 1 percentage point.

The Limited Cost Trader rules, introduced under Finance Act 2017, prevent businesses with very low goods expenditure from gaining a large windfall. Any business whose spending on goods is less than 2% of its VAT-inclusive turnover, or less than GBP 1,000 per year, is classified as a limited cost trader and must use a flat rate of 16.5%, eliminating most of the FRS benefit [SC5].

Businesses must leave the FRS if their total income (VAT-inclusive, including exempt supplies) exceeds GBP 230,000 in any 12-month period, unless HMRC is satisfied future income will not exceed GBP 191,500.

What is the VAT reverse charge and when does it apply?

The reverse charge is a mechanism that shifts VAT accounting responsibility from the supplier to the customer. It applies in two main contexts in the UK [SC6]:

Cross-border B2B services: Under Section 7A of the VAT Act 1994, when a UK VAT-registered business receives services from a supplier based outside the UK (for example, software licences, consulting, or digital services from a US or EU provider), the UK business accounts for both the output VAT and the input VAT on the same return. For fully taxable businesses this is cash-neutral; for partially exempt businesses it creates a genuine cost. The supplier does not charge UK VAT on their invoice.

Domestic construction reverse charge: Introduced 1 March 2021 under the VAT (Section 55A) Regulations 2019, this applies to most B2B supplies of building and construction services within the Construction Industry Scheme (CIS). The main contractor (customer) accounts for the VAT rather than the subcontractor. It was introduced to combat missing trader fraud in the construction sector. Key practical implication: subcontractors receive net-of-VAT payments and may frequently be in a VAT repayment position, affecting cash flow [SC6].

For the broader UK tax context, including how VAT registration interacts with corporation tax and self-employment income tax, see the United Kingdom country overview. Questions specific to your business structure, the interaction of partial exemption with your sector, or cross-border supply chains are best assessed with a UK qualified tax professional -- a member of the Chartered Institute of Taxation (CIOT) or a Chartered Accountant with VAT specialism.
