VAT Flat Rate Scheme: How It Works for UK Small Businesses in 2026

What is the VAT Flat Rate Scheme?

Under standard VAT accounting, a business generally calculates the VAT due by comparing:

• VAT charged on taxable sales, known as output VAT; and
• VAT that can be reclaimed on eligible business purchases, known as input VAT.

The Flat Rate Scheme uses a different calculation.

You charge VAT to customers using the normal VAT rules. However, instead of calculating input VAT and output VAT separately for most transactions, you apply a fixed percentage to your relevant VAT-inclusive turnover.

HMRC describes the scheme as a way of simplifying records for small businesses. Read HMRC’s VAT Flat Rate Scheme guidance

Importantly, the flat rate percentage is not the VAT rate you put on your invoice. Your invoices must still show the correct standard, reduced, zero or exempt VAT treatment for the supply.

Who can join the VAT Flat Rate Scheme?

You can generally apply if:

• you are, or are eligible to be, VAT registered;
• your expected VAT-taxable turnover for the next 12 months is £150,000 or less, excluding VAT; and
• you meet the other Flat Rate Scheme eligibility conditions.

The £150,000 figure is the Flat Rate Scheme entry threshold. It should not be confused with the compulsory VAT registration threshold.

The UK VAT registration threshold is currently £90,000 of VAT-taxable turnover, using the relevant statutory tests. If you are monitoring that threshold, see Real Key Accountancy’s VAT registration guide for sole traders.

Certain businesses cannot join. Restrictions can apply, for example, where you recently left the scheme, have certain connections with other businesses or use an incompatible VAT scheme. HMRC also prevents simultaneous use of the Flat Rate Scheme and the normal Cash Accounting Scheme, although the Flat Rate Scheme has its own cash-based turnover method.

How is Flat Rate Scheme VAT calculated?

The basic calculation is:

VAT-inclusive Flat Rate Scheme turnover × flat rate percentage = VAT payable under the scheme

Example: a photographer using an 11% flat rate

A photographer supplies standard-rated services worth £10,000 before VAT during a VAT period.

The business invoices:

• Net sales: £10,000
• VAT at 20%: £2,000
• Total VAT-inclusive sales: £12,000

HMRC’s current Flat Rate Scheme percentage for photography is 11%, assuming the limited cost business rate does not apply.

The Flat Rate Scheme calculation would therefore be:

£12,000 × 11% = £1,320

The business collected £2,000 of VAT from customers but pays £1,320 under the flat rate calculation.

However, the remaining £680 should not automatically be treated as a saving. Under the Flat Rate Scheme, the business generally gives up the right to reclaim VAT separately on its normal purchases.

You must therefore compare the whole VAT position, not simply the percentage charged to customers.

What VAT flat rate percentage should you use?

HMRC publishes different percentages for different business activities.

Current examples include:

These percentages apply where the limited cost business rules do not require the 16.5% rate. HMRC publishes the full current list of VAT Flat Rate Scheme percentages.

Choose the sector that most closely describes what your business will do during the coming year.

If your business carries out activities in more than one sector, HMRC generally requires you to use the percentage relating to the activity producing the largest part of your turnover. You do not normally divide turnover between several sector rates.

Keep a record explaining why you selected your sector, particularly where more than one category could reasonably fit.

What is a limited cost business?

The limited cost business rule is one of the most important parts of the VAT Flat Rate Scheme.

You are a limited cost business for a VAT period if your spending on relevant goods, including VAT, is either:

• less than 2% of your Flat Rate Scheme turnover; or
• more than 2% of that turnover but below £1,000 a year, adjusted for the length of the VAT period.

For a normal quarterly VAT return, the proportional £1,000 test is £250. A limited cost business uses a flat rate of 16.5%, regardless of its normal trade-sector percentage.

This test may need to be completed for every VAT period because a business can be a limited cost business in one quarter and not in another.

What counts as relevant goods?

This is where businesses often make mistakes.

The test is based on relevant goods, not every business expense.

Examples of potentially relevant goods include business stationery, qualifying stock, cleaning products and business-only gas or electricity. HMRC specifically excludes many items, including:

• services;
• accountancy fees;
• advertising;
• most vehicle costs and fuel, unless the specific transport-sector exception applies;
• food and drink for you or your staff;
• capital expenditure goods; and
• various goods bought for resale or disposal where the detailed conditions are not met.

Therefore, having significant business costs does not necessarily mean you escape the limited cost business rules.

A consultant might spend thousands each year on software subscriptions, accountancy, insurance and advertising. These are largely services rather than relevant goods for this test.

Why does the 16.5% limited cost rate matter?

A 16.5% flat rate sounds lower than the standard 20% VAT rate. However, the percentages are applied to different figures.

For £1,000 of standard-rated net sales:

• the customer pays £1,200 including VAT;
• 16.5% of £1,200 is £198.

Therefore, only £2 of the £200 VAT collected remains before considering VAT suffered on purchases.

That is why the Flat Rate Scheme often provides little financial advantage for a limited cost service business. HMRC itself warns that limited cost businesses may pay more VAT under the scheme than under standard accounting.

Is there a first-year Flat Rate Scheme discount?

Yes.

A business in its first year of VAT registration can normally reduce its applicable Flat Rate Scheme percentage by one percentage point.

For example, a 14.5% sector rate becomes 13.5% during the qualifying period.

A limited cost business using 16.5% can similarly use 15.5% while the reduction applies.

However, the discount runs from the date you became VAT registered, not from the date you joined the Flat Rate Scheme.

If you join six months after becoming VAT registered, you do not receive another full 12 months at the discounted rate.

Can you reclaim VAT on the Flat Rate Scheme?

Usually, you cannot reclaim VAT separately on everyday purchases.

That includes VAT on many costs that would potentially be reclaimable under standard VAT accounting. The flat rates are designed with an allowance for input VAT already built into them.

There is an important exception for capital expenditure goods.

You can generally reclaim VAT on a single purchase of qualifying capital expenditure goods costing £2,000 or more including VAT. The purchase is dealt with outside the Flat Rate Scheme.

The detailed definition matters. For example, combining several smaller purchases does not necessarily create one qualifying capital purchase.

This is one reason to review substantial equipment purchases before deciding which VAT scheme suits your business.

What turnover is included in the Flat Rate Scheme?

Flat Rate Scheme turnover can be wider than businesses expect.

HMRC requires relevant VAT-inclusive standard-rated, reduced-rated and zero-rated supplies to be included. Exempt business income can also be included, such as qualifying rental income. Certain non-business income and supplies outside the scope of UK VAT are excluded.

This can make the scheme less attractive where a business receives significant exempt or zero-rated income because the flat rate can still apply to that turnover.

Correct bookkeeping is therefore important even though the scheme simplifies the VAT calculation.

Real Key Accountancy offers bookkeeping and VAT support for sole traders and small businesses, including help with VAT records, digital record keeping and return preparation where agreed.

Does Making Tax Digital for VAT apply to the Flat Rate Scheme?

Yes.

Using the VAT Flat Rate Scheme does not remove Making Tax Digital for VAT obligations.

HMRC states that all VAT-registered businesses should now use Making Tax Digital for VAT unless an exemption applies. Businesses must keep the required VAT information digitally and submit VAT Returns using compatible software.

Flat Rate Scheme users must also retain a record of:

• Flat Rate Scheme turnover for each VAT accounting period;
• the percentage used;
• the resulting VAT due; and
• spending on relevant goods.

So, while the VAT calculation may be simpler, organised digital bookkeeping is still necessary.

Is the VAT Flat Rate Scheme worth it?

There is no universal answer.

The scheme may be worth considering where:

• your correct sector percentage is relatively low;
• you are not a limited cost business;
• you have relatively little input VAT to reclaim;
• most customers can recover the VAT you charge;
• the first-year reduction applies; or
• administrative simplicity is valuable to your business.

Standard VAT accounting may be more suitable where:

• you are regularly a limited cost business;
• you make significant VAT-bearing purchases;
• you expect major equipment or service costs;
• you have substantial exempt or zero-rated turnover included in the flat rate calculation; or
• your customers are consumers and VAT affects your pricing competitiveness.

The best comparison uses your actual or forecast sales and purchases.

Work out the expected VAT under standard accounting. Then calculate the Flat Rate Scheme liability using your correct sector rate and limited cost status.

Real Key Accountancy also provides free VAT and business calculators to help small businesses review VAT figures and thresholds.

Common VAT Flat Rate Scheme mistakes

Several mistakes can significantly change the amount of VAT due.

Applying the flat rate to net turnover

The percentage generally applies to VAT-inclusive scheme turnover, not the net sales figure. HMRC identifies using VAT-exclusive turnover as a common Flat Rate Scheme error.

Charging customers your flat rate percentage

Do not put 11%, 14% or 16.5% on an invoice simply because that is your Flat Rate Scheme percentage.

Charge VAT using the normal VAT rate applicable to the supply.

Ignoring the limited cost business test

Your sector might have a 10% rate, but that does not mean you can automatically use it.

If the limited cost rules apply during the period, the rate is normally 16.5%.

Counting services as relevant goods

Software subscriptions, advertising and professional fees may be genuine business expenses, but they do not become relevant goods simply because the business paid VAT on them.

Using the 1% reduction for too long

The first-year reduction ends immediately before the first anniversary of VAT registration. It does not restart when you join the Flat Rate Scheme.

Assuming the scheme is cheaper

Simplicity and financial savings are different questions.

Run both calculations before joining and review them again when circumstances change.

How do you join the VAT Flat Rate Scheme?

If you are not VAT registered, you can apply for the Flat Rate Scheme when registering for VAT.

If you are already VAT registered, HMRC allows eligible businesses to apply online or using form VAT600FRS. HMRC confirms your acceptance and the date from which the scheme applies. See HMRC’s Flat Rate Scheme application guidance

Do not start using the scheme simply because you have submitted an application. Make sure you know the approved start date.

When must you leave the Flat Rate Scheme?

The £150,000 entry threshold is not the same as the threshold for remaining in the scheme.

At the annual anniversary check, you normally become ineligible if your total income for the year ending then is more than £230,000 including VAT, excluding relevant capital asset sales. A separate forward-looking rule can require you to leave where there are reasonable grounds to believe income during the next 30 days alone will exceed £230,000.

There is a limited concession where an annual increase above £230,000 was unexpected and qualifying future turnover is expected not to exceed £191,500, but HMRC agreement and additional conditions are required.

You can also leave voluntarily. If you later want to rejoin, HMRC generally requires you to wait at least 12 months.

Should you choose the VAT Flat Rate Scheme?

The VAT Flat Rate Scheme can still be useful, but the headline percentage does not tell you whether it is right for your business.

Check four things first:

1. Confirm that you meet the eligibility rules.
2. Identify the correct HMRC business sector.
3. Complete the limited cost business test.
4. Compare the expected VAT cost against standard VAT accounting.

Repeat the comparison when your costs, turnover or business activities change.
