Flat Rate VAT Scheme: Is It Right for Your Business?

The flat rate VAT scheme is HMRC's simplified accounting option designed to reduce the admin burden on small businesses. Instead of tracking VAT on every purchase and calculating the difference between what you charge and what you pay, you pay a fixed percentage of your gross turnover to HMRC. It sounds straightforward—and for some businesses it is. But it's not always cheaper, and it's definitely not suitable for everyone. This guide walks you through how it works and whether it's the right choice for your business.

How the flat rate scheme actually works

Under the standard VAT scheme, VAT maths look like this:

Output VAT — 20% of what you charge customers
Input VAT — 20% of what you pay suppliers
You pay HMRC — the difference (output minus input)

The flat rate scheme throws this out. Instead, you apply a fixed percentage to your gross turnover (the money coming in, including VAT) and send that amount to HMRC each quarter. You still charge customers 20% VAT on your invoices, but you don't reclaim VAT on most of your business purchases. The flat rate percentage depends on your industry—HMRC publishes these in VAT Notice 733, and they range from 4% (retail food) to 16.5% (limited cost traders).

New VAT-registered businesses get a 1% discount in year one, so if your rate is 14.5%, you'd pay 13.5% while you're fresh to the scheme.

Flat rate percentages by industry

Here's the table from HMRC. If you're wondering which category applies to you: use the flat rate for whichever activity generates the most turnover. If your business type isn't listed, check the HMRC guidance on categorisation.

Industry	Flat rate %
Accountancy or bookkeeping	14.5%
Advertising	11%
Computer and IT consultancy	14.5%
Hairdressing or beauty	13%
Management consultancy	14%
Photography	11%
Pub or bar	6.5%
Restaurants or cafes	12.5%
Retail (food)	4%
Retail (non-food)	7.5%
Social work	11%
Transport or storage	10%

Who's actually eligible?

To join the flat rate scheme, you need:

VAT registration — You must be registered for VAT (see our guide to VAT registration for small businesses if you're not sure whether you're eligible)
Turnover under £150,000 (excluding VAT) in the next 12 months
No other simplified schemes — You can't use the margin scheme or capital goods scheme at the same time

You're forced to leave the scheme if your total business income (including VAT and non-VAT money) exceeds £230,000 in any rolling 12-month period. That includes cash you make outside VAT (grants, loans, insurance payouts)—not just sales.

The limited cost trader rule: where it gets real

This is the catch that catches a lot of businesses.

In 2017, HMRC introduced the "limited cost trader" category to stop pure service businesses from gaming the system. Here's how it works: if your spending on physical goods is less than either 2% of your VATable turnover or £1,000 a year (whichever is higher), you're classified as a limited cost trader. And if you're a limited cost trader, HMRC forces your flat rate to 16.5%—regardless of your industry.

What counts as goods? Physical products you sell, materials, office supplies, fuel. What doesn't? Services, capital assets (equipment over £2,000), staff snacks, vehicle costs other than fuel.

If you're a consultant, freelancer, or running a service business with minimal stock, this rule probably applies to you. And at 16.5%, the flat rate isn't actually saving you much versus the standard scheme—you're paying nearly 20% without the ability to reclaim purchases.

Before this rule, consultancies and agencies were getting away with flat rates of 11–14%, which was genuinely attractive. That loophole is closed.

When does it actually save money?

Run the numbers both ways. It's the only way to know.

The flat rate scheme typically saves money when:

You're a low-cost business (like a pub at 6.5%, or a food retailer at 4%) where the flat rate is genuinely much lower than 20%
You sell mainly to consumers who can't reclaim VAT anyway
Your expenses are genuinely low and you're not a limited cost trader

It typically costs more when:

You're a limited cost trader paying 16.5%
You have high VATable expenses that you'd reclaim under the standard scheme (office supplies, services, subscriptions, etc.)
Your profit margins are tight and you need every VAT saving you can get

Here's a worked example. Say you have:

Sales (excluding VAT): £120,000
Purchases (excluding VAT): £40,000
Your flat rate: 14.5%

Standard scheme:

Output VAT: £120,000 × 20% = £24,000
Input VAT: £40,000 × 20% = £8,000
VAT to pay HMRC: £24,000 − £8,000 = £16,000

Flat rate scheme:

Gross turnover (including VAT): £144,000
VAT to pay: £144,000 × 14.5% = £20,880

The standard scheme is cheaper by £4,880. But if your expenses drop to £5,000:

Standard scheme (low expenses):

VAT to pay: £24,000 − £1,000 = £23,000

Flat rate scheme:

VAT to pay: £20,880

Now the flat rate saves £2,120. The real-world lesson: your expense profile matters far more than your turnover.

Is the flat rate right for your business?

Ask yourself three questions:

Would the flat rate actually be cheaper? Run the sums. If the answer is "maybe, by a couple of hundred quid," move to question 2.
Is the saving worth the admin you'd save? If you're paying £500 less per year but tracking all your purchase VAT is manual hell, the flat rate might be worth it. If you're saving £5,000 per year, the standard scheme wins.
Will you still be eligible next year? If you're growing towards £230,000 total income or you're skirting the limited cost trader line, the flat rate might disappear on you mid-year. Standard scheme is more stable.

Relentify Accounting supports both schemes, so switching isn't a technical problem—it's just a matter of whether the numbers add up. Review your choice annually. Your expenses change, your turnover changes, your category might shift. What made sense in year one might not make sense in year three.

Getting it done: joining and leaving

To join: Tick the box when you register for VAT, or apply to HMRC online (or by post) anytime afterwards through your VAT online account. HMRC will confirm your flat rate percentage.

To leave: Write to HMRC. You can leave anytime voluntarily, or you're forced to leave if you exceed the £230,000 income threshold. When you leave, you move to the standard scheme from the start of the next VAT period. If you're thinking about switching schemes, tie it to a VAT quarter boundary to avoid mid-period confusion.

One practical tip: if you're trying to optimise your VAT, also think about your VAT return filing. Moving to flat rate doesn't exempt you from Making Tax Digital, but it does simplify what you're reporting. Also, explore what allowable business expenses you can claim—if you've got unrealised savings hiding in your purchases, the standard scheme is significantly better.

Frequently Asked Questions

Can I claim VAT on capital purchases under the flat rate scheme?

Yes. You can reclaim VAT on capital items worth £2,000 or more (including VAT) even if you're using the flat rate scheme. This is a valuable exception that many businesses miss. Keep these invoices separate so you can claim them on your VAT return.

What happens if I exceed the £230,000 income threshold mid-year?

You leave the flat rate scheme from the start of the next VAT quarter. You don't have to refund the flat rate payments you've already made that year. The switch happens at the quarter boundary, not immediately.

Do I still need to track my business expenses under the flat rate scheme?

Yes. Even though you can't reclaim input VAT, you still need to track expenses for income tax purposes and to determine whether the limited cost trader rule applies to you. If you're close to the 2% goods threshold, a few extra purchases could push you to 16.5%, which changes your VAT bill significantly.

Can I use the flat rate scheme part-year?

No. You join from the start of a VAT quarter and leave at the end of a quarter (or when you hit the income threshold). You can't switch mid-quarter.

Is the flat rate scheme worth it for a new business?

Usually, yes—at least in year one, because of the 1% discount. But do the maths before you sign up. If you're going to be a limited cost trader (high turnover, minimal goods purchases), the 16.5% rate might not be worth the simplicity trade-off.

How does the flat rate scheme interact with accounting software?

Modern accounting software handles both schemes. If you're using a tool that supports flat rate, you don't need to manually calculate VAT each invoice—the software does it for you. You just need to make sure you've set the right flat rate percentage and category.

What if my business does multiple types of work?

Use the flat rate for whichever activity generates the most turnover. If you do IT consultancy (14.5%) and also sell IT products (7.5%), you'd use 14.5%. If the split changes, your category might need updating.

The flat rate scheme is a genuine simplification tool—but only if the maths work and you're not caught by the limited cost trader rule. If you're running tight on time and the numbers are close, the simplicity might justify a slightly higher VAT bill. If you're trying to minimise tax, run the numbers both ways, and be honest about which scheme actually works for your business. Review it annually. What made sense when you registered might not make sense now.
