VAT is one of the most important and often most confusing taxes that UK businesses have to deal with. Whether you’re a sole trader just starting out, a growing limited company approaching the registration threshold, or an established business looking to manage your VAT obligations more efficiently, understanding how VAT works is essential.
In this guide, we break down everything you need to know about VAT in plain English covering the basics of how VAT works, the different rates that apply to goods and services, when to register, and the range of special VAT schemes available to smaller businesses.
What is VAT?
Value-Added Tax (VAT) is a consumption tax added to taxable supplies at each stage of the supply chain for most goods and services.
The general principle is that the customer ultimately pays the charge the Value-added tax (VAT). Each business in the supply chain will charge the next business VAT. And the business can generally reclaim this as long as they are VAT-registered.
Registering for VAT
Not all businesses charge VAT, even if they make taxable supplies.
A business can become VAT registered in two ways, compulsorily or voluntarily.
A business must register for VAT if it meets either of two turnover tests:
- The taxable turnover for the last 12 months exceeds £90,000.
- The expected taxable turnover in the next 30 days exceeds £90,000.
The first of these tests is a look back test that must be monitored on a monthly basis. Once the turnover exceeds £90,000, the business must register within 30 days of the end of the month it exceeded the threshold. For example, if a business exceeds the threshold on 9th July. The business must register by 30th August. Then it will be treated as registered business for VAT purposes from 1st September.
The second test requires some forecasting. Looking at invoices that are likely to be raised in the forthcoming month. If the expected turnover will exceed £90,000, the business must register by the end of the 30-day period. And it will be treated as VAT registered from the date they first realise the 30-day test will be met.
It is also possible to register voluntarily as long as there are at least some taxable sales. This can be a sensible option. If the customers are mainly VAT-registered businesses, they will be able to reclaim the additional charge anyway. If you’re unsure whether voluntary registration is right for your business, our VAT return service can help you weigh up the options.
Supplies and VAT
Taxable supplies are subject to VAT, but there are several different rates that apply.
The standard rate of VAT in the UK is 20%. This applies to most goods and services which are not exempt. However, there are three other rates to consider.
Reduced rate
Certain goods and services including children’s car seats and domestic energy products are subject to VAT at a reduced rate of 5%.
Zero rate
Some goods and services are taxable, but are subject to VAT at 0%. Examples include children’s clothing, sanitary products and most basic foodstuffs. It is important to understand that this is not the same as being exempt.
Exempt supplies and zero-rated supplies
Zero-rated supplies still count as taxable. Consequently, they are taken into account when looking at the registration tests. A business making zero-rated supplies can register for VAT, but a business making wholly exempt supplies cannot. A business that makes a mix of taxable and exempt supplies is said to be partially exempt. It can register for VAT, but is subject to special rules which restrict the amount of input tax it can claim.
For further information on which rates apply to specific goods and services, see the HMRC’s guidance.
Once a business is registered, it must comply with the VAT record keeping requirements.
In order to reclaim input tax on the VAT returns, the business must ensure that the invoices it receives from its own suppliers are valid VAT invoices, and that VAT has been correctly charged.
What is a valid VAT invoice? The information required to be shown on the invoice depends on whether it is a full invoice, or a simplified invoice for retail supplies under £250. HMRC has provided a table detailing what needs to be included on every VAT invoice.
Submitting VAT returns
A VAT return is due by the seventh of the second month following the end of a VAT quarter. For example, for the VAT quarter ended 31st March, the return is due by 7th May. Following the rollout of Making Tax Digital for VAT this must be done using HMRC compliant software. This software exports information from the accounting system to HMRC electronically via the Application Program Interfaces platform.

VAT Partial exemption
Partial exemption applies when a VAT-registered business makes a mix of both taxable and exempt supplies. Because VAT can only be reclaimed on costs that relate to taxable activities, a partially exempt business cannot reclaim all of its input VAT, only the portion that relates to its taxable sales.
Input tax that cannot be directly attributed to either taxable or exempt supplies is called residual input tax. This must be apportioned between the two types of activity. The amount apportioned to the taxable supplies can be included in the input tax claim on the VAT return. The amount apportioned to the exempt supplies cannot be recovered. That said, there are rules which allow full recovery of exempt input tax if the total value is insignificant.
As mentioned earlier, where a business makes both taxable and exempt supplies, special rules apply. These are needed because input tax can only be reclaimed to the extent it relates to taxable supplies. In many cases, this will be obvious for example, where a business purchases stock subject to standard rate VAT to sell onward. However, there will be some costs that relate to both taxable and exempt supplies such as heating and other overheads where the different activities are made from the same premises.
The standard method of apportionment is based on the turnover attributable to taxable and exempt supplies in the period. It is possible to agree a different method with HMRC. If the standard method doesn’t reflect the true split of cost centres between the activities.
The need for special schemes
VAT compliance, particularly with the introduction of Making Tax Digital, can be disproportionately difficult and complex for smaller businesses. The compulsory registration threshold of £90,000 is not a particularly large amount. A start up business can easily find itself being legally required to comply with the VAT legislation early in its life. Even where the threshold is not exceeded, the complexity and extra costs of VAT compliance may put businesses off registering voluntarily. Potentially costing them thousands of pounds in unclaimed input tax. HMRC offers a range of special VAT schemes designed to simplify the process and ease the administrative burden on businesses.
VAT schemes types
Flat Rate Scheme
What is the flat rate scheme?
The flat rate scheme, as the name suggests, is a scheme whereby you apply a flat rate of VAT to all of your sales, rather than the normal standard rate.
The flat rate scheme allows you to apply a single flat rate percentage to your turnover and ignore all the input VAT that your business has incurred.
If you run a food or drink business, read our dedicated guide to VAT on food and drinks for restaurants and cafes.
How does it work across industries?
Each industry has its own flat rate for the flat rate scheme. So, for instance, a pub might have a rate of 6.5%, a restaurant might have a rate of 12.5%.
If the business joins the flat rate scheme, it will simply aggregate the total VAT-inclusive sales in the period and apply a relevant percentage to this total. The result of this is the amount payable to HMRC.
However, when looking at VAT-inclusive turnover, everything that is within the scope of VAT must be included. So, if a business has zero-rated, reduced-rated, or exempt income, the turnover from these must be included in the VAT return calculation. For this reason, if a business is seeking to join the flat rate scheme that is about to make large sale that would be zero-rated or exempt, it will be worth considering delaying the joining date.
Under the flat rate scheme, the business does not account for its purchases, and so doesn’t recover input tax unless the expense is for a capital item and the VAT inclusive cost of the individual purchase exceeds £2,000.
The appropriate rate of VAT is still charged to the customer. The relevant percentage only applies to the VAT return when working out what is due to HMRC.
If you’ve got businesses which have more than one activity within them, perhaps a pub which sells food, then you need to look at the turnover within that business to determine which is the predominant activity, and then apply the flat rate scheme for that activity.
One special category relates to low-cost traders. If your costs of your business are below £250 a quarter, then you may need to apply to special low-cost rate, which is 16.5%. This would apply for people like management consultants for instance where essentially most of their costs are negligible, but their output is all standard rated.
Who can use the scheme?
The flat rate scheme is purely voluntary.
To join the scheme, a business must complete form VAT 600FRS.1 Once HMRC approves the application, the flat rate scheme can generally be used from the start of the next VAT period unless HMRC accept there is a good reason to start earlier.
In order to join the flat rate scheme:
- The business must be making taxable supplies, and therefore be eligible to register for VAT. Businesses making only exempt supplies are therefore excluded.
- The business cannot be associated with another business.
- The business’ expected taxable turnover excluding VAT in the next year must not exceed £150,000.
A business will be specifically excluded from the flat rate scheme if:
- It uses the second-hand margin scheme, tour operators margin scheme, or auctioneers scheme.
- It has to use the capital goods scheme.
- It was previously using the flat rate scheme and 12 months hasn’t elapsed since it left the scheme.
- It is, or has in the previous two years, been registered in the name of a VAT group or division, or was eligible to join an existing VAT group.
- In the previous year, it has accepted a compound penalty offer, been convicted of an offence in connection with that, or has been assessed with a penalty involving dishonest conduct.
- At the anniversary of the flat rate scheme start date the business’ total income (including VAT but excluding sales of capital assets) is more than £230,000
- There are reasonable grounds to believe the total value of the business’ income for the next 30 days alone will be more than £230,000 (excluding sales of capital assets).
Cash accounting VAT scheme
The cash accounting scheme allows small businesses to pay VAT on sales when their customers pay, and also to reclaim VAT on purchases when they have paid their supplier.
What is the cash accounting scheme?
The cash accounting scheme is a voluntary arrangement, whereby you can account for your VAT on a cash basis rather than on an invoice basis.
Traditionally, VAT is dealt with by reference to the date on an invoice, rather than date that invoice is paid. So you might sell some goods today and issue an invoice, you may not be paid for it for three or four months. You would account for the VAT on the date of the invoice. But under the cash accounting scheme, you can delay that until the invoice is actually paid. In the same way with goods you buy, normally you would account for the input VAT on the date of the invoice. But you can, under the cash accounting scheme, account for it on the date you actually pay for the goods or services.
What are the advantages and disadvantages?
The main advantage of the cash accounting system is cash flow.
Under the cash accounting system, you’re not paying the output VAT on your sales until you’ve actually been paid by your customers. This could be several months later if you’re offering standard credit terms. That means it’s not really an advantage if you’re in a retail operation where your customer is paying at the point of sale, because the downside is that you don’t recover your input VAT on your costs until you actually pay for them.
Eligibility
A business can only join the cash accounting scheme if:
- There are no VAT returns outstanding.
- The business has not been convicted of a VAT offence in the last year.
- The business has not accepted an offer to compound proceedings in connection with a VAT offence in the last year.
- The business has not been assessed to a penalty for VAT evasion involving dishonest conduct in the last year.
Restrictions
Some transactions cannot be accounted for under cash accounting scheme and must continue to be accounted for using standard VAT rules. The following are excluded to keep the scheme simple:
- Goods that are bought or sold under lease purchase, hire purchase, conditional sale or credit sale agreements.
- Goods imported or acquired from an EU member state, or goods removed from a customs warehouse or free zone.
- Certain goods on which the purchaser must account for output tax on their VAT return on the supplier’s behalf due to the reverse charge for example, for construction services between CIS-registered entities.
- Supplies where the business issues a VAT invoice and payment of that invoice is not due in full within six months of the date it was issued.
- Supplies of goods or services where the business issues a VAT invoice in advance of making the supply or providing the goods.
Leaving the scheme
The scheme is purely voluntary. But if your turnover exceeds £1.35m, then you’re excluded from the scheme.
If the business turnover exceeds £1.35m it may not have to leave the cash accounting scheme straight away. In fact, it can remain in the scheme until turnover exceeds £1.6M in a 12-month period. This is a “look back” test and needs to be done on a rolling basis.
Annual accounting VAT scheme
The annual accounting scheme aims to allow businesses to make advance VAT payments towards their VAT bill, based on their last return (or estimated if you’re new to VAT).
What is the annual accounting scheme?
The annual accounting scheme, as the name suggests, means you only need to submit one VAT return, once a year. This is a simplification to make life easier particularly for small businesses.
You’re eligible to join the scheme providing your turnover is below £1.35 million.
What are the advantages and disadvantages?
The main advantage of the annual accounting scheme is that you know exactly how much you’re going to be paying each month. Payments are made for nine months at a fixed rate, and then there’s a final tenth payment when you file your end of year return and then any additional VAT is paid or any excess VAT is recovered.
The main disadvantage would be, if you’re entitled to a refund, then you’re delaying that refund until you get to the end of the year.
Another advantage of the scheme is that you can combine it with the flat rate scheme.
Who can use this scheme?
The annual accounting scheme is a purely voluntary arrangement, but you must have a turnover below £1.35 million in order to enter the scheme.
Once you are in the scheme, you need to monitor your turnover, because if your turnover exceeds £1.6 million, then you need to exit the scheme.
Restrictions
A business cannot join the scheme, regardless of the level of expected turnover, if it:
- Is a member of a VAT group or division.
- Has, within the previous 12 months, ceased using the annual accounting scheme.
- Has an increasing VAT debt.
- Has entered insolvency proceedings.
Paying instalments
Once on the annual accounting scheme, a business will make nine instalments equal to 10% of the previous year’s annual VAT liability, or 10% of the estimated liability for the next 12 months.
The first payment is not due until the end of the fourth month of the annual period. The remaining payments are then due at the end of each month up to and including month 12.
It is possible to request quarterly instalments instead of monthly instalments if it suits the business. If this option is chosen, three instalments of 25% will be made by the end of months four, seven and 10, with any balance or refund being reconciled by the standard deadline – within two months of the end of the 12-month period.
Margin VAT scheme
What is the margin scheme?
The margin scheme for VAT involves paying VAT on the margin the profit you make on the sale of goods rather than the sales and purchases separately.
Normally with VAT, you pay output VAT on the sale of goods, and recover input VAT on the goods you’ve purchased, and you pay the difference over to HMRC. Under the margin scheme, you are only paying VAT on the profit margin you make. This is particularly useful for second-hand goods where you may not have had any input VAT on your purchase of goods, but when you sell them you’re likely to have charged standard rates.
Who can use the scheme?
Anybody can use the margin scheme if they’re buying and selling goods without recovering input VAT on the purchase. Typically, this will be second-hand goods, works of art, or antiques and things of that nature.
There is a special variation of the scheme which deals with second-hand cars and has its own particular rules and regulations.
What about keeping records?
In order to apply VAT to the margin on the sale of goods, you need to be able to identify not only what the selling price is, but also what the purchase cost was, so that you can work out the margin on which you’re applying the VAT. In order to do that, you need to keep detailed stock records of each individual item you buy and sell.
Eligibility and restrictions
Unlike some other schemes, there is no turnover limit on the general margin scheme.
This is because the scheme is aimed at certain types of business, rather than certain sizes. However, there are strict steps that must be followed when buying or selling goods which are set out in HMRC’s current guidance.
Goods must be eligible goods that have been acquired in eligible circumstances. Eligible goods include:
- Second-hand goods, including second-hand cars.
- Works of art, such as paintings and sketches.
- Antiques and collectors items – this does not include precious metals or stones.
Goods will generally be acquired in circumstances where no input tax has been reclaimed, or the business would have been entitled to reclaim it.
Leaving the scheme
The business can stop using the margin scheme at any time. It will simply change the way it accounts for VAT on the return, accounting for VAT on the full sales price instead of just the profit.
In conclusion
For many small businesses, the quarterly cycle of recording, calculating and submitting VAT returns can feel disproportionate to the size of the business itself.
Choosing the right scheme from the outset can save your business significant time, money, and administrative effort in the long run.
It is worth reviewing which scheme best suits your business regularly, as your business circumstances such as turnover, customer base, or cost structure change over time.
If you are unsure which VAT scheme is right for your business, speaking to an accountant early can help you avoid costly mistakes and ensure you are compliant from day one.

FAQs
What is the VAT registration threshold in the UK?
A business must register for VAT if its taxable turnover for the last 12 months exceeds £90,000, or if its expected taxable turnover in the next 30 days exceeds £90,000.
What is the difference between zero-rated and exempt supplies?
Zero-rated supplies are still classed as taxable, so they count towards the VAT registration threshold and a business making them can register for VAT. Exempt supplies, however, do not count as taxable. A business making wholly exempt supplies cannot register for VAT.
When is a VAT return due?
A VAT return is due by the seventh of the second month following the end of a VAT quarter. For example, for the quarter ending 31st March, the return is due by 7th May. It must be submitted using HMRC-compliant software under Making Tax Digital for VAT.
Can a business register for VAT voluntarily, and why might it choose to?
Yes, a business can register voluntarily as long as it makes at least some taxable sales. This can be advantageous for start ups where most customers are VAT-registered businesses themselves. As the business is in a grow stage with less or no revenue, registering voluntary for VAT can be of huge cash flow advantage.
What happens if I register for VAT late?
If your business exceeds the VAT registration threshold and you fail to register on time, HMRC can issue a penalty based on the amount of VAT that should have been paid during the period you were unregistered. The penalty percentage increases the longer you delay registerinmg ranging from 5% for being up to nine months late, up to 15% for being over 18 months late. You will also be liable to pay all the VAT that should have been charged to customers during that period, even if you didn't actually collect it from them.
Can I reclaim VAT on purchases made before I registered?
Yes, in many cases you can. HMRC allows businesses to reclaim VAT on goods purchased up to four years before the date of VAT registration, provided the goods are still on hand at the point of registration.
