The Flat Rate VAT Scheme Explained

The Flat Rate VAT Scheme lets eligible small businesses pay a single fixed percentage of turnover to HMRC instead of working out VAT on every sale and purchase. It can simplify your VAT admin, but it doesn't suit everyone. Here's how it actually works and how to tell if it's worth joining.

Key Takeaways

• You pay a fixed percentage of your gross turnover instead of calculating VAT line by line.
• You can join if your VAT-taxable turnover is £150,000 or less, and you must leave once it passes £230,000.
• If you're a "limited cost trader," meaning you spend very little on goods, you're required to use a 16.5% rate regardless of sector, which often wipes out any saving.
• You generally can't reclaim VAT on purchases, except capital assets costing £2,000 or more including VAT.
• Service-heavy businesses and those trading internationally often don't benefit as much as businesses that buy a lot of physical goods.

What Is the Flat Rate VAT Scheme?

The Flat Rate Scheme is an alternative way to calculate what VAT you owe HMRC. Instead of tracking VAT on every individual sale and purchase, you apply one fixed percentage to your gross turnover.

That percentage depends on your business sector, whether that's catering, photography, or IT consultancy, and it's set by HMRC to roughly reflect the average VAT costs businesses in that sector already carry. You still charge your customers VAT at the standard 20% rate. The scheme only changes what you hand over to HMRC, not what you charge.

Who Can Join the Flat Rate VAT Scheme?

You can join if you're VAT registered and your expected VAT-taxable turnover is £150,000 or less over the next 12 months, excluding VAT. This is a fixed HMRC threshold, so check it applies to your business before assuming you're eligible.

You'll need to apply to join the scheme yourself. It's not automatic, and it's worth getting advice from an accountant or a formation agent before you do. Our VAT registration support can help with the application if you'd rather not handle it alone.

You can't join if any of the following apply:

• You left the scheme within the last 12 months
• You've committed a VAT offence, such as evasion, in the past year
• You're closely linked, financially or organisationally, to another business
• You joined, or were eligible to join, a VAT group in the last 24 months
• You're on a margin or capital goods VAT scheme

You also can't combine the Flat Rate Scheme with the Cash Accounting Scheme.

When Do You Have to Leave the Scheme?

You must leave once your VAT-inclusive turnover goes over £230,000 in a 12-month period. This is the exit threshold, separate from the £150,000 entry threshold, and it catches some businesses out if turnover grows quickly.

If you're approaching either threshold, it's worth reviewing your position early rather than waiting to be forced out mid-year. Switching schemes partway through a year adds admin you can plan around instead.

What's the "Limited Cost Trader" Rule?

If your business spends very little on goods, HMRC classifies you as a "limited cost trader" and requires you to use a flat rate of 16.5%, regardless of your actual sector rate. This single rule is why many service businesses no longer benefit from the scheme.

You're a limited cost trader if your spending on goods, not services, is either under 2% of your turnover or under £1,000 a year, whichever is higher. Software subscriptions, subcontractor fees, and professional services don't count as goods for this test. Only physical items used in your business do, and even then, food, drink, and vehicle costs are excluded.

This matters because 16.5% of your VAT-inclusive turnover is very close to the full 20% VAT you're charging. For a lot of consultants, freelancers, and other service-based businesses, that leaves little to no saving compared with standard VAT accounting.

Worked Example: How the Calculation Works

Say your flat rate is 14% and your gross (VAT-inclusive) turnover for a quarter is £12,000. You'd calculate your VAT bill like this:

• Gross turnover: £12,000
• Flat rate at 14%: £1,680
• Total VAT owed to HMRC: £1,680

Compare that to standard VAT accounting, where you'd charge 20% VAT on sales and reclaim VAT on your purchases separately. Depending on how much you actually spend on VAT-able costs, the flat rate can work out cheaper, more expensive, or roughly the same. It genuinely depends on your specific numbers, not just your sector.

Can You Reclaim VAT on Purchases?

No, not generally. Under the Flat Rate Scheme, you can't reclaim VAT on day-to-day purchases, because the fixed percentage you pay is already set to account for that.

The one exception is capital assets costing £2,000 or more, including VAT. If you buy equipment above that threshold, you can usually reclaim the VAT on it separately, even while on the scheme.

When the Flat Rate Scheme Doesn't Pay Off

The scheme tends to suit businesses that spend a reasonable amount on physical goods relative to turnover. It tends to suit service-heavy businesses less well, and it gets more complicated if you trade internationally.

If you're a contractor or consultant with low spending on goods, the limited cost trader rule likely pushes you to 16.5%, which can erase most of the benefit. If your business buys or sells goods from outside the UK, such as running a dropshipping operation, the flat rate calculation gets more complicated to apply correctly, and it's worth getting professional advice before committing either way.

FAQs

What's the turnover limit to join the Flat Rate VAT Scheme?

Your VAT-taxable turnover needs to be £150,000 or less, excluding VAT, over the next 12 months. You must leave once your VAT-inclusive turnover exceeds £230,000.

What is a limited cost trader?

It's a business that spends very little on goods, either under 2% of turnover or under £1,000 a year. Limited cost traders must use a 16.5% flat rate regardless of sector.

Can I reclaim VAT on purchases under the Flat Rate Scheme?

Generally no, except for capital assets costing £2,000 or more including VAT, which you can usually still reclaim VAT on.

Is the Flat Rate VAT Scheme worth it for a service business?

Often not, if the limited cost trader rule applies to you. At 16.5%, the saving compared with standard VAT accounting is usually small or nonexistent for low-goods-spend businesses.

Do I still charge customers 20% VAT under the Flat Rate Scheme?

Yes. The scheme only changes how much you pay HMRC, not the VAT rate you charge your customers.

How do I apply to join the scheme?

You apply directly through HMRC. It's not automatic once you're VAT registered, and it's worth getting advice from an accountant before applying.
