VAT Flat Rate Scheme — Is It Worth It for Your UK Business? (2026)

How the Flat Rate Scheme works

Under the standard VAT scheme, you charge 20% VAT on sales, reclaim VAT on purchases, and pay HMRC the difference. Under the Flat Rate Scheme (FRS), you charge customers 20% VAT as normal, but you pay HMRC a fixed percentage of your gross turnover (inclusive of VAT) — and keep the difference.

The fixed rates vary by trade sector, ranging from 4% for retailers of food, confectionery, newspapers and children's clothing to 16.5% for limited cost businesses.

You do not reclaim VAT on most purchases under FRS (except for certain capital assets over £2,000 on a single invoice). You trade the right to reclaim input tax for the simplicity of a single fixed calculation.

Who can use FRS?

You can join the Flat Rate Scheme if your expected VAT taxable turnover (excluding VAT) for the next 12 months is no more than £150,000. You must leave FRS once your annual VAT-inclusive turnover exceeds £230,000.

The limited cost business rate

HMRC introduced a 16.5% FRS rate for "limited cost businesses" in 2017, specifically to prevent service businesses from benefiting from the scheme. You are a limited cost business if your VAT-inclusive expenditure on goods is either:

• Less than 2% of your VAT-inclusive turnover, or
• Less than £1,000 per year

This catches most service businesses — consultants, IT contractors, freelancers, bookkeepers. At 16.5%, FRS is rarely beneficial for limited cost businesses because the saving over standard VAT accounting is minimal and sometimes negative.

When FRS is genuinely beneficial

The scheme works best for trade sectors with low input VAT — where you buy little and sell a lot of service. A typical example:

• Accountancy firm, FRS rate 14.5%
• Annual turnover: £100,000 + VAT = £120,000 gross
• FRS payment: £120,000 × 14.5% = £17,400
• Standard VAT: Output tax £20,000 – Input tax £2,500 = £17,500
• FRS saving: £100 (minimal — and no reclaim on purchases)

The saving was larger before the limited cost business rate was introduced. Now it is worth doing the maths carefully before joining.

How to calculate whether FRS saves you money

1. Estimate your annual gross turnover (VAT-inclusive)
2. Find your sector's FRS rate on HMRC's website
3. Multiply: gross turnover × FRS rate = FRS annual payment
4. Estimate your standard VAT position: output tax – input tax reclaim
5. Compare the two

If the FRS payment is lower than your standard VAT position, FRS saves money. But always factor in time savings — FRS is simpler to administer, which has a value beyond the pure tax saving.

Joining and leaving FRS

Apply through your HMRC VAT online account or through your bookkeeper. HMRC will confirm your FRS rate. You can leave FRS voluntarily at any time; you must leave if you exceed the £230,000 threshold.

Note: The first year on FRS can be confusing for bookkeeping because you are charging 20% VAT but paying a different rate. Your software (Xero, QuickBooks) handles this with a dedicated FRS VAT rate code — make sure your bookkeeper sets this up correctly from the start.
