Half the people I've put on the Flat Rate Scheme over the years saved a few hundred pounds a year. The other half lost more. The maths is simple — the trick is doing it before you opt in, not after.
What the Flat Rate Scheme is
Under the standard VAT system, you charge customers VAT (typically 20%), reclaim VAT on your business purchases, and pay HMRC the difference. Under the Flat Rate Scheme (FRS), you still charge customers 20%, but instead of doing the in/out maths you simply pay HMRC a fixed percentage of your gross VAT-inclusive turnover.
The percentage depends on your trade sector — between 4% (retail of food and confectionary) and 14.5% (computer and IT consultancy, accountancy, legal services). HMRC sets these so that the average business in each sector pays roughly the same as it would under standard VAT.
You also get a 1% discount in your first year as a VAT-registered business, which is the headline reason most people first consider FRS.
Eligibility & turnover limits
- To join: your VAT-taxable turnover (excluding VAT) must be £150,000 or less in the next 12 months
- To stay in: total business income (including exempt and outside-the-scope income, but excluding VAT) must be £230,000 or less. Above that, you must leave at the next anniversary
- You must not have been convicted of a VAT offence in the last 12 months, registered for VAT as part of a group, or be associated with another business in a way that makes the scheme inappropriate
Sector rates explained
HMRC publishes a list of approximately 55 sector categories, each with its own flat rate. Some common examples for 2026:
| Sector | Flat rate |
|---|---|
| Accountancy or book-keeping | 14.5% |
| Computer and IT consultancy or data processing | 14.5% |
| Management consultancy | 14% |
| Estate agency or property management services | 12% |
| Hairdressing or other beauty treatment services | 13% |
| Hotel or accommodation | 10.5% |
| Photography | 11% |
| Printing | 8.5% |
| Pubs | 6.5% |
| Retailing food, confectionary, tobacco, newspapers or children's clothing | 4% |
| Transport or storage, including couriers, freight, removals and taxis | 10% |
| "Any other activity not listed elsewhere" | 12% |
The complete list is in HMRC's flat rate categories table. If you're genuinely unsure, ask HMRC in writing — getting the wrong category for years is expensive.
The limited cost trader trap (16.5%)
The 2017 change that broke FRS for most service businesses
From 1 April 2017, HMRC introduced a "limited cost trader" classification with a flat rate of 16.5%. If your VAT-able goods purchases are less than 2% of your turnover (or less than £1,000 a year), you fall into this bucket regardless of your sector.
The test is applied every VAT period, not just at year-end. You need to check it on each return.
Two important points about the test:
- It's goods only — services (software subscriptions, accountant fees, marketing, training) don't count, even though you pay VAT on them
- It excludes capital expenditure, food/drink for staff, and vehicles, parts, fuel (unless you're a transport business)
For a typical solo consultant whose only "goods" purchases are stationery and a laptop every few years, the limited cost trader test fails most quarters. 16.5% on gross of 20%-VAT-inclusive sales works out to about 19.8% of net sales — almost the same as standard VAT, with no input recovery. FRS becomes worse than the standard scheme.
Worked example: B2B consultant on the standard rate
Sarah runs a B2B marketing consultancy. £80,000 turnover, £8,000 of VAT-inclusive expenses (mostly software, no goods). She's an "Advertising" sector business with a flat rate of 11%.
But here's the catch: she's a limited cost trader (no goods purchases). So her flat rate is 16.5%, not 11%.
| Standard VAT | Flat Rate (16.5%) | |
|---|---|---|
| Output VAT charged on £80k net sales (×20%) | £16,000 | £16,000 (still charged) |
| VAT to pay HMRC | £16,000 − input VAT | 16.5% × £96,000 gross = £15,840 |
| Input VAT recovered (20% of £8k gross expenses → £1,333) | £1,333 | £0 |
| Net VAT cost to business | £14,667 | £15,840 |
FRS costs Sarah £1,173 a year more than the standard scheme. If she's in her first year, the 1% discount drops the FRS rate to 15.5%, giving £14,880 — still worse than standard VAT.
Worked example: hospitality business that benefits
James runs a small pub. £180,000 turnover, £40,000 of VAT-inclusive goods purchases (drinks stock, food). Sector flat rate: 6.5%. He passes the limited cost trader test (goods are 22% of turnover).
| Standard VAT | Flat Rate (6.5%) | |
|---|---|---|
| Output VAT charged on £180k sales (×20%) | £36,000 | £36,000 (charged) |
| VAT to pay HMRC | £36,000 − input VAT | 6.5% × £216,000 gross = £14,040 |
| Input VAT recovered (£40k goods × 1/6 = £6,667; plus £2k other = ~£333) | £7,000 | £0 |
| Net VAT cost to business | £29,000 | £14,040 |
FRS saves James £14,960 a year. The maths works because pub goods purchases are large relative to turnover.
When FRS still works in 2026
- High-goods, low-margin businesses — pubs, restaurants, retailers
- Some hospitality and accommodation where the sector rate is favourable
- First-year voluntary registrations with the 1% discount, especially if you'll only be VAT-registered briefly
- Lifestyle businesses who value the simplicity over a few hundred pounds of marginal VAT
When to leave FRS (and how the CIS reverse charge breaks it)
If you're a construction subcontractor and the CIS Domestic Reverse Charge applies to your work, FRS becomes nearly always wrong. The reason: under reverse charge you don't charge output VAT, but FRS calculates the VAT you owe HMRC as a percentage of your gross sales — including reverse charge sales. So you'd be paying 9.5% (the construction rate) of sales on which you collected nothing. We see subcontractors lose thousands a year by not leaving FRS after March 2021.
Other triggers to leave:
- You're now a limited cost trader (run our flat rate calculator at the start of each VAT period)
- You've started buying significant equipment / capital items where you'd prefer to reclaim the input VAT
- Your turnover is approaching £230k inc-VAT — you'll be forced out anyway
- You moved to mostly zero-rated sales
How to join or leave
Joining: apply via your HMRC online VAT account, by phone, or by post (form VAT600FRS). HMRC usually approves within 30 days.
Leaving: write to HMRC. There's no fixed minimum stay. Effective date is normally the start of the next VAT period after your letter, unless you're being forced out under the £230k rule (in which case it's the next anniversary).
FAQ
Does the 1% first-year discount apply to the 16.5% limited cost trader rate?
Yes, but only in your first year of VAT registration. So a limited cost trader in year one pays 15.5%, not 16.5%.
Can I switch between FRS and standard VAT mid-year?
Yes — leaving is at HMRC's discretion but normally allowed at the start of any VAT period. Joining is also possible at any period start, subject to eligibility.
What about VAT on capital assets over £2,000?
You can reclaim input VAT on capital expenditure goods over £2,000 (inc VAT) on a single invoice, even on FRS. This is the only input VAT you reclaim while on the scheme. Track these separately on your return.
Does FRS interact with the Annual Accounting Scheme?
Yes — you can be on both simultaneously. Annual Accounting changes when you submit and pay (annually, plus interim payments), FRS changes how you calculate. Many sole traders use both.
