Standard versus Flat Rate side by side, with the limited-cost-trader test built in. Agencies are nearly always limited-cost traders (16.5% rate on gross turnover), so the standard scheme usually wins after reclaiming input VAT.

Standard vs Flat Rate for agencies

On the Standard scheme you charge 20% VAT and can reclaim input VAT on purchases. On the Flat Rate Scheme you charge 20% to clients but pay HMRC a flat percentage of your VAT-inclusive turnover instead of tracking input/output separately.

Most agencies trigger the Limited Cost Trader (LCT) test because their goods spend is low (below 2% of VAT-inclusive turnover or £1,000/year). LCT companies must use the 16.5% flat rate, which usually makes the Flat Rate Scheme more expensive than standard.

Frequently asked questions

What is the Limited Cost Trader test?
If your VAT-inclusive goods spend is below £1,000/year OR below 2% of your VAT-inclusive turnover, you are a Limited Cost Trader and must use the 16.5% flat rate. Services, software and staff costs do not count as goods for this test.
