When you register for VAT in the UK, there are different ways to account for the VAT you owe HMRC. Different VAT accounting methods exist, and choosing the right one can affect the amount of VAT your business pays to HMRC, the input VAT it can recover and the level of administration involved.
Under flat rate and standard VAT schemes, you charge VAT at the appropriate rate for the goods or services you supply. The difference is how you calculate the VAT due to HMRC. Under normal VAT accounting, businesses generally deduct eligible input VAT from the VAT charged on their taxable sales. Under the Flat Rate Scheme, businesses normally calculate the amount due by applying an HMRC-set percentage to their VAT-inclusive flat rate turnover.
The Flat Rate Scheme is designed to simplify VAT accounting for eligible small businesses. Instead of calculating the VAT due by deducting eligible input VAT from output VAT in the usual way, you generally apply the relevant Flat Rate Scheme percentage to your VAT-inclusive flat rate turnover.
Flat Rate Scheme percentages vary by business sector. For example, HMRC's rates in September 2026 include 14% for management consultancy and 7.5% for retailing that is not listed elsewhere. Businesses must identify the correct HMRC trade sector for their activities.
Here is how it works step by step:
As of September 2026, VAT-registered businesses must generally keep digital records and submit VAT returns using Making Tax Digital-compatible software, unless an exemption applies.
The Flat Rate Scheme can simplify VAT administration because the calculation is generally less complex than under normal VAT accounting. Businesses must still keep appropriate records and comply with Making Tax Digital requirements.
For businesses registering for VAT for the first time, establishing reliable bookkeeping processes early can make VAT reporting significantly easier.
The standard VAT scheme is the usual way UK businesses account for VAT. Under normal VAT accounting, you charge VAT on taxable supplies at the appropriate rate and can generally reclaim VAT on eligible business purchases, subject to the normal VAT recovery rules. For each VAT accounting period, you calculate the difference between the VAT due on your sales and the VAT you are entitled to reclaim on your purchases.
Here is a simple breakdown:
Normal VAT accounting may suit businesses that regularly incur significant amounts of recoverable input VAT on eligible costs. Where a business regularly incurs VAT on eligible costs, normal VAT accounting may provide greater opportunities to recover that VAT.
VAT-registered businesses must generally follow Making Tax Digital for VAT requirements and use compatible software to keep VAT records and submit VAT returns, unless an exemption applies.
Many businesses choose professional support to help manage VAT submissions, maintain accurate records, and reduce the risk of reporting errors.
When comparing flat-rate VAT vs standard VAT, the biggest difference lies in how you calculate what you owe HMRC. The Flat Rate Scheme generally uses a sector-based percentage applied to VAT-inclusive turnover, while normal VAT accounting calculates VAT due after deducting eligible input VAT from output VAT.
| Flat Rate Scheme | Standard Scheme | |
| How you calculate VAT | Flat rate % applied to VAT-inclusive flat rate turnover | Output VAT minus input VAT |
| Claim VAT back on purchases | Generally no, except for certain qualifying capital expenditure goods | Generally, subject to the normal VAT recovery rules |
| Admin level | Generally simpler | Generally more detailed |
| Best for | May suit eligible businesses with relatively low recoverable input VAT | May suit businesses with significant recoverable input VAT |
The Flat Rate Scheme may simplify VAT calculations for some eligible businesses, but it is not automatically more beneficial for businesses with low expenses. In particular, businesses that fall within the limited cost rules may have to use the 16.5% rate. Normal VAT accounting may be more suitable where a business regularly incurs significant amounts of recoverable input VAT. Comparing the expected liability under both methods is therefore important.
VAT-registered businesses must generally keep digital records and submit their VAT returns using Making Tax Digital-compatible software, unless an exemption applies.
The most suitable approach depends on factors including your costs and the amount of input VAT you are entitled to recover. Businesses with significant recoverable input VAT may find normal VAT accounting more favourable.
Not every business can use the flat rate scheme. HMRC has specific rules about who can join.
Other circumstances can also make a business ineligible for the scheme, so eligibility should be checked against current HMRC guidance.
Businesses in their first year of VAT registration can generally reduce their applicable flat rate percentage by 1 percentage point until the day before the first anniversary of becoming VAT registered. If a business joins the Flat Rate Scheme after registering for VAT, the reduction does not restart from the date it joins the scheme.
The 1 percentage point reduction can affect the comparison between the Flat Rate Scheme and normal VAT accounting during a business's first year of VAT registration.
It is also worth reviewing the Flat Rate Scheme percentage that applies if your main business activity changes, as the appropriate HMRC sector is based on the nature of the business.
Businesses should review their eligibility periodically, particularly if turnover increases or trading activities change.
A simple example helps show how the calculations differ.
Example: Assume an IT consultancy makes £20,000 of standard-rated sales before VAT during a VAT accounting period. It charges £4,000 VAT, meaning customers pay £24,000 in total. Assume the business uses the 14.5% Flat Rate Scheme percentage, is not a limited cost business and is not applying the first-year reduction.
Under the Flat Rate Scheme:
Under normal VAT accounting:
In this simplified example, the Flat Rate Scheme produces a VAT liability £20 lower than normal VAT accounting. The result would change if the business had more recoverable input VAT, qualified for the first-year reduction or fell within the limited cost business rules.
If the business were a limited cost business, it would generally use the 16.5% rate instead of its normal sector percentage. The VAT comparison should therefore be recalculated using the business's actual figures for the relevant VAT period.
Normal VAT accounting may be more advantageous where a business regularly incurs substantial amounts of recoverable input VAT.
Normal VAT accounting may be worth considering if you are:
Normal VAT accounting can become more attractive where a business incurs increasing amounts of eligible recoverable input VAT. The effect depends on the nature of the expenditure, the VAT charged and whether the business is entitled to recover it.
Businesses that make substantial zero-rated supplies should assess the Flat Rate Scheme carefully. Although no output VAT is charged to customers on zero-rated supplies, those supplies can still form part of the turnover used in the Flat Rate Scheme calculation. Under normal VAT accounting, a business making taxable zero-rated supplies may still be able to reclaim eligible input VAT. This can make normal VAT accounting more favourable in some circumstances.
Comparing expected VAT liabilities under both schemes can clarify their long-term financial impact. For further guidance on reclaiming input VAT, visit HMRC's official VAT guidance.
The limited cost business test should be checked carefully before using the Flat Rate Scheme because it can significantly affect the amount of VAT payable.
You are generally treated as a limited cost business for a VAT period if the amount spent on relevant goods, including VAT, is either:
Under HMRC rules current as at September 2026, limited cost businesses generally use a Flat Rate Scheme percentage of 16.5%, regardless of their normal business sector.
What counts as goods?
What does not count as relevant goods?
For businesses that fall within the limited cost rules, the 16.5% rate can reduce the financial advantage of the Flat Rate Scheme, so it is important to compare the expected VAT liability under both methods.
Businesses whose spending on relevant goods is close to the threshold should check the test for each VAT period, as they may move between the 16.5% limited cost rate and their normal sector rate.
The ability to reclaim input VAT can significantly affect the comparison between the two methods.

Choosing an appropriate VAT accounting method can affect cash flow, the amount of VAT recoverable and the administrative work involved.
It is also worth reviewing your scheme regularly. A scheme that suits the business initially may become less appropriate as turnover, costs or trading activities change.
Not necessarily. The more suitable method depends on factors including the business's Flat Rate Scheme percentage, recoverable input VAT and whether the limited cost business rules apply.
Generally not. However, you may reclaim VAT on certain single purchases of qualifying capital expenditure goods costing £2,000 or more including VAT, provided HMRC's conditions are met.
A limited cost business is a business whose spending on relevant goods falls below HMRC's specified thresholds for a VAT period. Where the test applies, the business generally uses a Flat Rate Scheme percentage of 16.5%.
Yes. Businesses can leave voluntarily or may be required to leave if they no longer meet HMRC's eligibility requirements.
Yes. Businesses can leave the Flat Rate Scheme and move to the Standard VAT Scheme if it better suits their circumstances.
Yes. The Flat Rate Scheme simplifies VAT calculations, but businesses must still maintain appropriate records and comply with Making Tax Digital requirements.
VAT rates, Flat Rate Scheme percentages, eligibility thresholds, and HMRC guidance can change over time. The information in this article reflects the position as at September 2026 and is intended as general guidance only.
The Flat Rate Scheme and normal VAT accounting can produce different results depending on your turnover, business activities, costs and recoverable input VAT. The limited cost business rules may also affect whether the Flat Rate Scheme is suitable.
Review the figures periodically, particularly if your turnover, costs, or business activities change. If you need help understanding how the rules apply to your circumstances, Red Fish Accountancy can guide you on your VAT options and ongoing reporting requirements.
