VAT Scheme Comparator
Picking the wrong VAT scheme costs four-figure sums a year for most service businesses. Run your turnover and input VAT through the comparator to see whether the Flat Rate Scheme beats Standard VAT for you, and whether the Limited Cost Trader rules would force you onto the 16.5% sector rate anyway.

VAT element of your business costs — software, freelancers if VAT-registered, equipment. Standard scheme reclaims this; flat rate does not.
Spend on physical goods used in the business. Excludes services, software, stationery for own use, travel, capital items. For most service businesses this is very low.
Limited Cost Trader rate (16.5%) applies because goods spend is below 2% of VAT-inclusive turnover or £1,000. Flat Rate is rarely beneficial for service businesses with LCT status.
Sense-check your figure with an accountant
Calculators give you a solid starting point, but the final number depends on timing, reliefs you may not have considered, and how different taxes interact. A quick conversation with one of our accountants puts a firm figure on it, with no obligation.
Standard vs Flat Rate
Under the Standard scheme you charge 20% VAT, reclaim the VAT on your costs, and pay HMRC the difference. Under the Flat Rate scheme you still charge 20% but pay HMRC a fixed percentage of your VAT-inclusive turnover instead, with no input VAT reclaim.
The Limited Cost Trader test catches most service businesses: if your goods spend is below 2% of VAT-inclusive turnover or £1,000, HMRC applies a 16.5% flat rate instead of your sector rate. At 16.5%, the Flat Rate scheme almost never wins against Standard.
Frequently asked questions
- What is the Limited Cost Trader (LCT) rule?
- If your spending on physical goods is less than 2% of your VAT-inclusive turnover, or less than £1,000 per year, HMRC classifies you as a Limited Cost Trader and applies a flat rate of 16.5%. This applies to most service businesses, consultancies, and digital agencies.
- Can I switch VAT schemes at any time?
- You can join the Flat Rate Scheme if your taxable turnover is below £150,000 (and leave if it exceeds £230,000). You must notify HMRC before switching. There is no minimum time you must remain on a scheme, but frequent switching may attract scrutiny.
- What about Cash Accounting?
- Cash Accounting can be combined with either scheme. Under Cash Accounting you account for VAT when you receive payment, not when you raise an invoice. It is cash-flow positive if you have long payment terms with clients (60+ days) and is available if turnover is below £1.35 million.
