VAT Flat Rate Scheme: still worth it after the Limited Cost Trader rules?
The Flat Rate Scheme used to be a quiet win for service businesses. Then HMRC introduced the Limited Cost Trader category in April 2017, forcing most consultants, IT contractors and freelancers onto a 16.5% flat rate. After that rate, FRS usually loses you money.
The maths
On standard VAT, you reclaim input VAT on purchases. On FRS, you charge 20% VAT to customers but pay HMRC a flat percentage of your gross (VAT-inclusive) turnover.
At 16.5%, a £100 + VAT invoice generates:
- Output VAT charged: £20
- Owed to HMRC: 16.5% × £120 = £19.80
- Net VAT cost to the business: £0.20
Compared to standard accounting, where you'd typically recover £5–£15 of input VAT a quarter, the LCT rate almost always loses.
Who still benefits
- Trades with significant goods purchases — caterers, retailers, builders
- New businesses in their first year (1% discount on the FRS rate)
- Businesses on a sector rate below 11% with low input VAT
What to do at year-end
For every client still on FRS, run the LCT test against the latest 12 months of purchases. If they're a Limited Cost Trader and on 16.5%, switching to standard accounting is almost always worth it. Write to HMRC, leave on the chosen date, and reclaim input VAT going forward.
