Flat Rate VAT Calculator UK — FRS Rates by Sector (2026/27)

What Is the VAT Flat Rate Scheme?

The Flat Rate Scheme (FRS) is an HMRC scheme that simplifies VAT for small businesses. Instead of calculating the difference between output VAT and input VAT on every transaction, you pay a single fixed percentage of your gross (VAT-inclusive) turnover directly to HMRC.

You still charge your clients the standard 20% VAT rate on every invoice. The benefit comes from the difference between what you collect and what you pay HMRC — depending on your sector rate, you keep that margin.

Use the VAT Calculator homepage Flat Rate tab to calculate your FRS payment for any sector instantly.

How the Flat Rate Scheme Works

The formula is straightforward:

FRS Payment = Gross (VAT-inclusive) Turnover × Your Flat Rate %

Example — IT consultant at 14.5%:

Invoice raised:        £10,000 net
VAT charged (20%):     £2,000
Gross invoice total:   £12,000

FRS payment to HMRC:   £12,000 × 14.5% = £1,740
VAT you collected:     £2,000
Amount you keep:       £2,000 − £1,740 = £260

That £260 is yours. Across a year of consistent invoicing, it adds up.

The Limited Cost Trader Rule — Read This First

In 2017, HMRC introduced the limited cost trader category specifically to prevent service businesses with minimal goods costs from profiting excessively from the scheme.

You are a limited cost trader if your VAT-inclusive goods expenditure in a quarter is less than:

  • 2% of your VAT-inclusive turnover, OR
  • £1,000 — whichever is greater

If either condition applies, you must use 16.5% — regardless of your sector.

At 16.5%, the maths rarely favours the FRS. A business paying 16.5% of gross effectively pays around the same as under standard VAT accounting — but loses the ability to reclaim input VAT on purchases. For most limited cost traders, the standard VAT scheme is the better choice.

Before joining FRS, always check whether the limited cost trader rule applies to your business.

Is the Flat Rate Scheme Worth It?

It Works Well For:

  • Service businesses with very low goods costs and a sector rate well below 16%
  • Businesses where simplified bookkeeping saves time and accountancy fees
  • High-margin B2B service providers with predictable turnover
  • Businesses in their first year of VAT registration (HMRC offers a 1% discount in year one)

It Is Less Suitable For:

  • Businesses caught by the limited cost trader rule (16.5%)
  • Businesses with significant VATable purchases — you cannot reclaim input VAT under FRS
  • Businesses making capital purchases over £2,000 — reclaim is blocked under FRS (with limited exceptions)
  • Turnover approaching the £150,000 join threshold

FRS Eligibility Rules

Rule Detail
Join the scheme VAT-taxable turnover of £150,000 or less (excluding VAT)
Must leave the scheme Total VAT-inclusive turnover exceeds £230,000
First year discount Use a rate 1% lower than your sector rate in the first year of VAT registration
Capital goods Can reclaim VAT on single capital purchases of £2,000 or more (VAT-inclusive) outside FRS rules

FRS and the VAT Registration Threshold

You can only join the Flat Rate Scheme once you are VAT registered. Registration is required when your taxable turnover exceeds £90,000 in any rolling 12-month period.

If you are voluntarily registered below the threshold, you can still apply to join FRS — provided your expected turnover stays below £150,000.

How FRS Interacts With the Reverse VAT Calculation

Under FRS you still issue invoices showing 20% VAT. Your clients — if VAT-registered — reclaim that 20% as normal. From their perspective, nothing changes.

You still need to understand the reverse VAT calculation to verify the VAT shown on your own purchase invoices, even though you cannot reclaim it under FRS.

Frequently Asked Questions

Can I reclaim input VAT under the Flat Rate Scheme?

Generally no. Under FRS, you pay a flat rate and cannot reclaim input VAT on day-to-day purchases. The exception is capital assets costing £2,000 or more (VAT-inclusive) — you can reclaim VAT on these outside the flat rate calculation.

What is the first-year FRS discount?

In your first year of VAT registration, HMRC allows you to reduce your flat rate percentage by 1%. An IT consultant normally at 14.5% pays 13.5% in year one.

When must I leave the Flat Rate Scheme?

You must leave when your VAT-inclusive annual turnover exceeds £230,000, or if you expect it to in the next 12 months. You can also leave voluntarily at any time.

Does FRS affect my VAT return?

Yes. Under FRS, your VAT return is simpler — one calculation instead of reconciling every invoice. But you still file quarterly returns through MTD-compliant software.
