VAT Flat Rate Scheme vs Standard VAT: Which Suits Your Business?

Choosing between the Standard VAT scheme and the Flat Rate Scheme affects both how much VAT you pay and how much admin is involved. There are other VAT accounting methods too, but these two are the ones most small businesses compare when registering for VAT or reviewing their current setup. Sector flat rates vary considerably, so the right VAT scheme for one business isn’t necessarily right for another in a different trade. Here’s how each works, and how to tell which suits your business.

The Standard VAT scheme

Under standard VAT, the mechanics are straightforward:

1. Charge VAT on your sales (output VAT)
2. Reclaim VAT on your business purchases (input VAT)
3. Pay HMRC the difference each quarter (or reclaim a refund if input VAT exceeds output VAT)

Tracking both input and output VAT on every sale and purchase is what gives standard VAT its reputation for extra admin compared with the Flat Rate Scheme.

This is the default VAT accounting method most VAT-registered businesses use, and it’s the only option once turnover grows past the Flat Rate Scheme’s limits. Every VAT-registered business, whichever scheme it uses, still needs to keep VAT invoices and submit a VAT return each quarter, usually via Making Tax Digital-compatible software.

The Flat Rate Scheme (FRS)

Under the Flat Rate Scheme, you still charge VAT to customers in the normal way, but instead of reclaiming input VAT on purchases and paying HMRC the difference, you pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover, as explained on GOV.UK’s VAT Flat Rate Scheme page. This flat rate percentage depends on your trade sector, and sector rates generally sit lower than the standard 20% VAT rate to reflect the fact you’re not reclaiming input VAT, HMRC’s published sector rates range from around 4% up to 14.5%, before the separate 16.5% limited cost trader rate can override them.

The trade-off: you generally can’t reclaim VAT on purchases, with one exception, capital assets costing more than £2,000 (including VAT) can still have their VAT reclaimed separately. Because you’re not reclaiming input VAT, any VAT-inclusive amount you keep after paying HMRC its fixed percentage effectively becomes part of your income, so the scheme trades a simpler VAT return for giving up individual purchase reclaims.

Eligibility and thresholds

• You can join if your VAT-taxable turnover (excluding VAT) is expected to be £150,000 or less over the next 12 months
• You must leave the scheme once your total income including VAT exceeds £230,000 in a 12-month period
• There’s a 1% discount off your sector’s flat rate during your first year of VAT registration

The 16.5% limited cost trader rate

A specific rule catches businesses with very low goods purchases. If your VAT-inclusive spending on goods (not services, and excluding things like food, drink, fuel for a car, and capital items) is less than 2% of your VAT-inclusive turnover, or under £1,000 a year even where that’s more than 2%, you’re classed as a limited cost trader and must use a 16.5% flat rate instead of your normal sector percentage.

This mainly affects service-based businesses, consultants, IT contractors, and similar, who buy very little in the way of physical goods. For many of these businesses, 16.5% of gross turnover works out close to, or sometimes more than, what they’d pay under standard VAT, which significantly narrows the Flat Rate Scheme’s appeal for this group.

Other VAT accounting schemes worth knowing

Standard VAT and the Flat Rate Scheme aren’t the only options. Two others come up often enough to be worth a mention, though neither changes how much VAT you owe, only when you account for it:

• Cash Accounting Scheme: instead of accounting for VAT when you invoice or are invoiced, you account for output VAT when your customer actually pays you, and input VAT when you actually pay your supplier. This can help cash flow if customers pay slowly, since you’re not paying HMRC VAT you haven’t yet collected.
• Annual Accounting Scheme: instead of a VAT return every quarter, you make advance payments toward your VAT bill and file one VAT return a year. This reduces the admin of quarterly returns, though most businesses still need to budget carefully for the balancing payment.

Both are aimed at businesses below a similar turnover threshold to the Flat Rate Scheme, and both can be combined with standard VAT accounting. A VAT Margin Scheme also exists, but it’s a specialist scheme for secondhand goods, art, and antiques rather than a general alternative to standard or flat rate VAT.

Which suits which business?

Getting the choice right

Picking the right VAT scheme for your business under UK VAT rules depends on your sector’s flat rate percentage, how much you spend on VATable goods, and how close you are to the thresholds, it isn’t a decision to make on the headline percentage alone. Getting it wrong in either direction can quietly add to your VAT costs over a full year. Your overall VAT liability can end up higher or lower on the Flat Rate Scheme depending on these factors, so it’s worth reviewing actual figures rather than assuming the lower-looking percentage automatically wins. An accountant can run both calculations against your real turnover and purchase pattern before you decide.

Switching between schemes also has a practical side beyond the numbers: the VAT return itself is completed differently, and figures like turnover reported in Box 6 are calculated on a different basis under the Flat Rate Scheme than under standard VAT, so the transition needs to be handled carefully in the accounting software, not just decided on paper.

Our VAT Returns service reviews which scheme genuinely saves you money and handles the switch (and the quarterly returns) either way. Our free VAT calculator can help with quick sums in the meantime.
