The VAT Flat Rate Scheme was designed to reduce VAT administration for small businesses — and for some, it also produces a modest profit by allowing them to keep a percentage of the VAT they collect. Whether it works in your favour depends almost entirely on whether you qualify as a limited cost trader under HMRC's rules introduced in 2017.
- FRS: pay a fixed % of VAT-inclusive turnover to HMRC instead of tracking every transaction
- FRS rate varies by sector — most IT/professional services: 14.5%
- Limited cost traders (most consultants): 16.5% — FRS rarely worthwhile
- First year of VAT registration: 1% discount on your FRS rate
- Capital goods over £2,000 VAT-inclusive: can reclaim VAT even on FRS
How the Flat Rate Scheme works
Standard VAT accounting requires tracking every purchase and sale, calculating the VAT on each, and paying HMRC the difference (output VAT minus input VAT). The Flat Rate Scheme simplifies this: you pay a fixed percentage of your total VAT-inclusive turnover to HMRC, regardless of how much input VAT you actually paid.
The scheme was designed to help small businesses reduce VAT admin. A secondary benefit: businesses with low costs could keep the difference between the VAT they collected (20%) and the flat rate they paid — effectively a profit on the VAT transaction.
Worked example: standard IT consultant on FRS
- Invoice to client: £10,000 net + £2,000 VAT = £12,000 VAT-inclusive
- FRS rate for IT (Management Consultancy or Computer and IT Services): 14.5%
- Amount paid to HMRC: £12,000 × 14.5% = £1,740
- VAT collected: £2,000
- Surplus kept: £2,000 − £1,740 = £260
But this only works if you are not a limited cost trader (see below).
Common FRS sector rates for directors
| Business type | FRS rate |
|---|---|
| Computer and IT services | 14.5% |
| Management consultancy | 14.0% |
| Accountancy and bookkeeping | 14.5% |
| Engineering and technical consulting | 14.5% |
| Legal services | 14.5% |
| Limited cost trader (any sector) | 16.5% |
The full HMRC rate table covers 56 business categories. Use the rate that most closely describes your business — if in doubt, your accountant can confirm the correct sector.
The limited cost trader problem
Since April 2017, HMRC has applied a 16.5% flat rate to businesses that spend very little on physical goods — a category they call 'limited cost traders'. If your goods expenditure is less than 2% of your VAT-inclusive turnover, or less than £1,000/year, you are a limited cost trader and must use the 16.5% rate.
Most IT contractors, management consultants, and professional service businesses are limited cost traders — they spend almost nothing on physical goods. At 16.5%, the FRS calculation becomes:
- VAT collected: £12,000 × (20/120) = £2,000
- FRS payment: £12,000 × 16.5% = £1,980
- Surplus: just £20
At this level, the administrative saving of FRS rarely justifies staying in the scheme. Most limited cost trader consultants are better off on standard VAT accounting. See the separate guide on the limited cost trader rule.
The first-year 1% discount
In the first year of VAT registration, you can deduct 1 percentage point from your flat rate. A 14.5% rate becomes 13.5% for 12 months from the date of VAT registration. This discount applies to the flat rate — not just to whether you are a limited cost trader. Even limited cost traders get 15.5% in year one.
Capital goods exception
Under FRS, you generally cannot reclaim input VAT on purchases. However, there is one important exception: capital expenditure goods costing more than £2,000 VAT-inclusive. On a single purchase of qualifying goods above this threshold, you can reclaim the VAT separately from the FRS calculation. This is particularly relevant if you buy a high-value computer, specialist equipment, or office furniture.
Is FRS right for you?
| Scenario | FRS verdict |
|---|---|
| High-expense business with significant goods purchases (>2% turnover) | Worth assessing — may reduce VAT liability |
| Low-expense consultant or IT contractor | Likely limited cost trader — FRS rarely worthwhile at 16.5% |
| In first year of VAT registration, lower rate applies | Potentially worth it for year 1 with the 1% discount |
| Accountant uses FRS for simplicity | Fine if savings justify fees; check annually |
Common mistakes
- Not checking limited cost trader status — joining FRS expecting the sector rate, then discovering you qualify as a limited cost trader at 16.5%, is a costly surprise.
- Forgetting the first-year discount — must be claimed; it is not automatic in all software. Confirm with your accountant when you register.
- Applying FRS rate to net turnover — the flat rate applies to VAT-inclusive turnover (gross amount including VAT). Applying it to net amounts understates your payment.
- Staying on FRS after it stops being beneficial — check annually whether FRS still makes sense. Business models change.
