VAT Flat Rate Scheme and the Limited Cost Trader Trap in 2026/27
Service businesses on the VAT Flat Rate Scheme may be 'limited cost traders' paying 16.5% -- leaving almost no benefit. Learn which businesses are affected and better alternatives.
When the VAT Flat Rate Scheme was introduced, it offered service businesses a genuine profit -- pay 12% of gross turnover to HMRC but collect 20% from customers, keeping an 8% margin. HMRC closed this loophole in 2017 with the "limited cost trader" category, setting a special 16.5% rate that leaves almost nothing for businesses that spend very little on physical goods. Millions of UK freelancers, contractors, and consultants remain on the FRS unaware that it now offers them virtually no benefit.
How the Flat Rate Scheme works
Under the FRS, a VAT-registered business does not track input VAT (VAT paid on purchases) and output VAT (VAT charged to customers) separately. Instead:
- You charge customers VAT at the standard rate (20% on standard-rated supplies).
- You pay HMRC a fixed percentage of your gross (VAT-inclusive) turnover -- the percentage depends on your business sector.
- The difference between what you charge customers and what you pay HMRC is yours to keep.
Example (pre-limited cost trader rule): An IT consultant charges £10,000 net + £2,000 VAT = £12,000 gross. The old FRS rate for computer services was around 14.5% of gross = £1,740 to HMRC. The consultant kept £2,000 - £1,740 = £260 per month as a VAT profit.
Now under the 16.5% limited cost trader rate: Same consultant pays £12,000 x 16.5% = £1,980 to HMRC. Keeps only £20 -- barely worth the administration.
The limited cost trader test in detail
The test must be applied to each VAT return period. For a quarterly return:
Step 1: Calculate your goods costs for the period.
Goods means physical items -- stationery, cleaning materials, postage stamps, small supplies you consume in running the business. Items that do NOT count as goods for this test:
- Services of any kind (software licences, cloud subscriptions, phone contracts, accountancy, insurance).
- Capital expenditure (computers, furniture, vehicles, office equipment).
- Food or drink for you or your staff.
- Vehicles or vehicle parts/fuel.
Step 2: Compare goods costs to 2% of your gross VAT-inclusive turnover for the quarter.
- If goods costs are less than 2% of gross turnover (or less than £250 per quarter, proportioned from £1,000 per year): you are a limited cost trader for that period.
- You must use 16.5% for that period even if your normal sector rate is lower.
Example: A marketing consultant has quarterly gross turnover of £30,000. They buy £200 of stationery in the quarter.
- 2% of £30,000 = £600.
- Goods costs £200 are less than £600.
- Must use 16.5% for this quarter: £30,000 x 16.5% = £4,950 to HMRC.
- Standard VAT collected: £5,000. Net to keep: £50.
Standard VAT accounting vs FRS for service businesses
Under standard VAT accounting, a business:
- Charges 20% VAT on all standard-rated sales.
- Pays all output VAT to HMRC.
- Reclaims all input VAT on business purchases.
- Net payment = output VAT minus input VAT.
For a consultant spending £5,000 net per year on business expenses (software, equipment, professional fees -- all standard-rated), standard accounting provides £1,000 of input VAT recovery per year. The FRS at 16.5% would provide almost nothing. The comparison:
| VAT accounting method | Annual cost to HMRC (£100k net turnover) |
|---|---|
| Standard (assume £5k input VAT) | £20,000 output VAT - £1,000 input VAT = £19,000 |
| FRS at 16.5% (£120k gross) | £19,800 |
In this example, standard accounting saves £800 per year. For businesses with higher input VAT (larger software stacks, more equipment), the advantage of standard accounting is even greater.
When the FRS still makes sense
The FRS remains genuinely beneficial for businesses where goods costs are substantial relative to turnover:
- Plumbers and electricians buying significant materials.
- Caterers and restaurants with high food costs (but note food can be zero-rated so may not count).
- Retailers where stock costs are a large fraction of turnover.
- Florists or gift shops where physical goods dominate.
These businesses can use their sector-specific FRS rate (which may be 6-10%), collect 20% VAT, and retain a genuine margin -- the original purpose of the scheme.
Alternatives to the FRS
If you are a limited cost trader for whom the FRS offers no benefit, the alternatives are:
Standard VAT accounting: Full input VAT recovery on all business purchases. More record-keeping but usually financially superior for service businesses with any meaningful costs.
Cash accounting scheme: VAT is accounted for when cash is actually received and paid, not on an invoice basis. This can improve cash flow for businesses with slow-paying customers. Compatible with standard VAT accounting.
Annual accounting scheme: You make monthly or quarterly interim VAT payments based on the previous year's liability and file a single annual VAT return. Reduces administration. Available to businesses with taxable turnover under £1.35 million.

What is the VAT Flat Rate Scheme?
The Flat Rate Scheme (FRS) is a simplified VAT accounting method for small businesses with taxable turnover under £150,000 (ex-VAT). Instead of tracking VAT on every purchase and sale, you pay a fixed percentage of your gross (VAT-inclusive) turnover to HMRC and keep the difference. The percentage varies by business sector from around 4% to 14.5%.
What is a 'limited cost trader'?
A limited cost trader is a business where the cost of goods (excluding services, capital assets, food, and vehicles) is less than 2% of VAT-inclusive turnover, or less than £1,000 per year. Most service businesses -- IT contractors, consultants, accountants, financial advisers, copywriters, marketing agencies -- fall into this category because they buy very few physical goods.
What FRS percentage does a limited cost trader pay?
Limited cost traders pay a flat rate of 16.5% of gross (VAT-inclusive) turnover to HMRC. Since VAT is collected at 20% of net turnover (equivalent to 16.67% of gross), paying 16.5% leaves only 0.17% of gross turnover as a saving -- essentially no benefit at all. For most limited cost traders, the FRS produces no financial advantage over standard VAT accounting.
Why was the limited cost trader rate introduced?
HMRC introduced the 16.5% limited cost trader rate in April 2017 to tackle FRS abuse. Before 2017, service businesses could exploit the FRS by paying 12-13% of gross turnover to HMRC while charging 20% VAT, pocketing a significant profit margin that HMRC considered inappropriate. The 16.5% rate eliminated almost all of this profit for businesses with minimal goods costs.
How is the limited cost trader test applied?
The test is applied each VAT return period. In any period, if your goods costs (correctly calculated) are less than 2% of your gross turnover OR less than £1,000 per year (proportioned to the period), you must use the 16.5% rate for that period -- even if you use a lower sector rate in other periods. You must test each period separately.
What counts as 'goods' for the limited cost trader test?
Goods for the limited cost trader test means physical items you buy to use in your business -- things like office stationery, small equipment, or materials. Excluded from 'goods' are: services (software subscriptions, accountancy fees, phone bills), capital items (computers, office equipment), food and drink for personal consumption, and vehicles or vehicle parts. This makes the test difficult to pass for most service businesses.
Should a limited cost trader leave the Flat Rate Scheme?
In most cases, yes. If you are a limited cost trader, the FRS provides no meaningful benefit -- you pay 16.5% to HMRC and charge 20% to customers. By contrast, standard VAT accounting lets you reclaim all input VAT on business costs. If you have significant VAT on business expenses (professional subscriptions, software, broadband, laptops), standard accounting will likely result in less VAT being paid overall.
Are there sectors where the FRS still works despite the limited cost trader test?
The FRS still benefits businesses with significant goods costs relative to turnover -- retailers, manufacturers, caterers, and tradespeople who buy materials. For example, a carpenter whose materials cost 15% of turnover can use a sector rate well below 20% and retain a genuine margin. The limited cost trap mainly affects pure service businesses.
What are the VAT registration threshold conditions for FRS?
You can join the FRS if your taxable turnover in the next 12 months will not exceed £150,000. You must leave the FRS if your turnover (including VAT) exceeds £230,000 in the previous 12 months. The standard VAT registration threshold (requiring you to be registered at all) is £90,000 of taxable turnover.
