VAT accounting can feel complex, but understanding it is a must for every UK business. Whether you’re registering for the first time or reviewing your accounting processes, staying on top of VAT rules protects your business from fines, keeps cash flow predictable and ensures compliance with HMRC. It’s important – and we’re here to help you get it right.
We’ll break down everything you need to know about VAT: when to register, the different accounting schemes available, what you can reclaim and how the Making Tax Digital initiative affects your business. By the end, you’ll have the clarity and tools to manage VAT confidently – and minimise administrative headaches.
Key takeaways:
- VAT registration is mandatory once turnover exceeds £90,000 – but you can also register voluntarily to reclaim VAT or boost business credibility.
- Choosing the right VAT accounting scheme matters. Standard, Flat Rate, Cash Accounting and Annual Accounting schemes each have pros and cons depending on cash flow and administrative capacity.
- Making Tax Digital requires digital records. Spreadsheets alone are no longer enough; compliant software is essential.
- Accurate VAT record-keeping reduces risk. Clear documentation ensures you reclaim the right VAT and avoid penalties or interest.
What is VAT?
VAT (Value Added Tax) is a consumption tax charged on most goods and services sold in the UK. VAT-registered businesses add VAT to their sales, collect it from customers and pass it on to HMRC through their VAT return.
Businesses can also reclaim VAT they’ve paid on eligible business expenses.
VAT rates in the UK
There are three main VAT rates in the UK:
- Standard rate (20%) – applies to most goods and services, such as most drinks, confectionary and adults’ clothing
- Reduced rate (5%) – applies to certain items such as children’s car seats and some energy-saving materials
- Zero rate (0%) – applies to most food, books and children’s clothing
Applying the wrong rate can result in penalties, so it’s essential to double-check which rate applies to your products or services directly with HMRC.
When do you need to register for VAT?
You must register for VAT if:
- Your taxable turnover exceeds £90,000 in the last 12 rolling months
- You expect your turnover to exceed £90,000 in the next 30 days
Note: this is based on a rolling 12-month period – not your financial year.
You can also voluntarily register below the threshold. This can make sense if:
- You mainly sell to VAT-registered businesses
- You incur significant VAT on expenses
- You want to appear more established

VAT registration isn’t automatically beneficial; it depends on your customer base, cost structure and growth plans.
How to register for VAT
Most businesses register online via the Government Gateway.
When you register, you’ll create a VAT online account, which you’ll use to submit returns.
You’ll need:
- Government Gateway login details
- Business information
- Bank account details
You can also appoint an accountant or VAT agent, provided they meet HMRC’s agent standards. You must formally authorise them to act on your behalf.
In limited circumstances (such as applying for a registration exception or joining the Agricultural Flat Rate Scheme), you may register by post using a VAT1 form.
UK VAT accounting schemes explained
Choosing the right VAT accounting scheme affects both your cash flow and administrative workload.
What’s best for your company depends on:
- Your turnover
- How quickly customers pay you
- How much VAT you reclaim
- Your internal finance capacity
Let’s break them down.
Standard VAT accounting
Standard VAT accounting is the default VAT scheme. With standard VAT accounting, you must keep a record of all your purchases and sales and the amount of VAT you paid or charged. With this method, VAT payments are recorded on the date invoices are raised, rather than the date they’re paid.
If you charged more VAT on goods and services than you paid on allowable business expenses, you’ll owe HMRC money. If you paid out more VAT than you charged then HMRC may owe you money.
If you’re considering the standard method of VAT accounting, it’s worth reviewing your cash flow and whether your clients are prompt payers. With this method, if the invoice is raised you’ll already owe HMRC the VAT even if your customer hasn’t paid you yet.
VAT Flat Rate Scheme
The VAT Flat Rate Scheme means you work out your VAT as a percentage of your annual turnover.
It's a bit easier to get to grips with than standard VAT accounting as it's a simpler process with less paperwork. HMRC created the Flat Rate Scheme for small businesses to reduce the extra administration time VAT registration costs.
To be eligible for the VAT Flat Rate Scheme you have to be VAT registered, and your VAT taxable turnover must be less than £150,000 before VAT.
The exact percentage you use varies from industry to industry. For example, post offices pay 5% whilst legal services pay 14.5%. Check out the government’s website to find the right percentage for your business.
With the Flat Rate Scheme, you can actually keep the extra money if you end up collecting more VAT from customers than you need to give to HMRC. But you can’t reclaim VAT that you’ve paid on allowable business expenditure unless it's a capital asset worth over £2,000.
VAT Cash Accounting Scheme
The VAT Cash Accounting Scheme is similar to standard VAT accounting. The difference is that everything is based on the payment date, not the invoice date. This can be a great option for businesses that need to keep a close eye on cash flow and don’t always have enough in the bank to cover their quarterly VAT.
One downside is that it works both ways: you can’t reclaim VAT on supplier invoices until you’ve actually paid them.
Annual Accounting Scheme
As the name suggests, with the VAT Annual Accounting Scheme you’ll be doing your VAT return annually instead of quarterly. It's similar to standard VAT accounting, as you pay based on what’s been invoiced not what’s been paid.
Though you only do your VAT return once a year, in the year leading up to it you pay towards what you estimate the VAT you owe will be. So payments are spread out across the whole year, which can be better for cash flow.
Sometimes this results in companies over or underpaying HMRC. So when you do your VAT return at the end of the year you may have to pay extra or request some money back.
To join the VAT Annual Accounting Scheme you must have a VAT taxable turnover lower than £1.35 million, and your turnover has to stay at less than 1.6 million to remain in the scheme.
VAT retail schemes
Retail businesses selling high volumes of low-value goods can use special schemes to simplify calculations:
Point of Sale Scheme
The Point of Sale Scheme is where VAT is identified and recorded the moment you sell something, so it’s useful if you have an electronic till. You’d then add up all the sales that you need to pay VAT on, and divide it by 6 for 20% rated goods and 21 for 5% rated goods.
Apportionment Scheme
The Apportionment Scheme is for goods you’ve bought for resale. It allows you to calculate the total value of goods purchased for resale rather than having to do each one individually.
You cannot use apportionment if you provide:
- Services
- Goods that you’ve made or grown yourself
- Catering services
Direct Calculation Scheme
The Direct Calculation Scheme is a good option if you make a small number of sales at one VAT rate, and a large number of sales at another. It's a simple way to work out your VAT bill using expected selling prices (ESP) without having to look at each individual transaction.
Your annual turnover before VAT has to be lower than £1 million to be eligible for the direct calculation scheme.
VAT margin schemes
VAT margin schemes are designed to tax the difference between the cost of the item when you bought it versus the cost of the item when you sold it. You then pay a VAT rate of 16.67% on the difference between the two costs.
It’s commonly used for trades like:
- Second-hand goods
- Works of art
- Antiques
- Collectors’ items
You cannot use the VAT margin scheme for:
- Goods where VAT was already reclaimed
- Precious metals
- Investment gold
- Precious stones
These schemes have strict record-keeping requirements, so make sure to stay on top of them.
Submitting your VAT return
Once you’re VAT registered, you’ll receive a certificate of registration.
The next time you log into HMRC online and register for VAT Online Services you must provide your:
- VAT registration number
- Effective date of registration for VAT
- The final month of the last VAT return you submitted (if applicable)
- Business' postcode
You’re now ready to submit your VAT returns online. Fab!
You’ll be asked to provide the details on your:
- Total sales and purchases
- VAT charged
- VAT reclaimed
Unless, of course, you’re using a VAT scheme that works differently.
The frequency of your VAT return – monthly, quarterly or annually – will also depend on which scheme you’ve chosen.
VAT penalties and interest
If you file late, pay late or submit inaccurate returns, HMRC may apply:
- Default surcharge periods
- Financial penalties
- Interest charges
Interest on underpaid VAT is not tax-deductible and can accumulate over time.
If you overpay VAT, you may claim interest – but you must apply separately within four years of the repayment authorisation date.
What VAT can you reclaim?
You can reclaim VAT on most business expenses, including:
- Stock
- Equipment
- Tools
- Office supplies
- Software
You cannot reclaim VAT on:
- Business entertainment
- Personal expenses
- Fuel used for personal mileage
- Goods bought under the second-hand margin scheme
- Supplies used to make VAT-exempt sales
Make sure to stay on top of your records: keeping clear digital records is essential to support claims!
VAT and bad debt relief
If you’ve paid VAT to HMRC on an invoice that remains unpaid, you may be able to claim bad debt relief if:
- The debt is between six months and 4.5 years old
- You haven’t sold the debt
- You charged a normal commercial price
If the customer later pays, you must repay the reclaimed VAT in your next VAT return.
VAT penalties and late payment rules
If you miss a VAT return deadline, HMRC now uses a points-based penalty system.
Late VAT return submissions
- Each late submission earns one penalty point
- Once you reach a points threshold, you’ll receive a £200 penalty
- Every additional late submission while above the threshold triggers another £200 penalty
The threshold depends on how often you submit returns:
- Annual returns: 2 points
- Quarterly returns: 4 points
- Monthly returns: 5 points
Points expire after a period of compliance.
Late VAT payments
Late payment penalties are separate and based on how overdue the payment is:
- 0–15 days late: no penalty if paid within 15 days
- 16–30 days late: 2% of the VAT outstanding at day 15
- 31+ days late: 2% at day 15 plus 2% at day 30
- Ongoing penalty: daily interest accrues from day 31
HMRC also charges statutory interest on late payments from the due date until the balance is paid in full.
Incorrect VAT returns
If you submit inaccurate VAT returns – for example, by underpaying VAT or over-claiming input VAT – penalties depend on the reason:
- Careless errors
- Deliberate errors
- Deliberate and concealed errors
The more serious the issue, the higher the penalty.
Making Tax Digital for VAT
Under the UK government’s Making Tax Digital initiative, VAT-registered businesses must:
- Keep digital VAT records
- Submit VAT returns using MTD-compatible software
- Maintain digital links between systems
Failure to comply can result in penalties or rejected submissions.
Note: manual spreadsheets without digital links may not meet compliance standards. To find accounting or bridging software compatible with the government’s online VAT portal, check out the government’s website.
