VAT Flat Rate Scheme UK: the real pricing cost

The VAT Flat Rate Scheme (FRS) is supposed to make life easier for small businesses. And it does — one flat percentage, one simple calculation, less time doing VAT returns.

But it comes with a pricing trap that catches most FRS businesses by surprise.

What the Flat Rate Scheme actually is

Under standard VAT, you collect 20% VAT from clients and pay HMRC the difference between what you collected and what you paid on purchases. Net-net accounting.

Under FRS, you charge clients 20% VAT as normal. But instead of net accounting, you pay HMRC a flat percentage of your *gross* (VAT-inclusive) turnover — and keep the rest.

The flat rate varies by business type:

In your first year on FRS, you get a 1% discount on your rate.

How the numbers work

You're an IT consultant. You invoice a client £1,000 + 20% VAT = £1,200 gross.

Under FRS at 14.5%: you pay HMRC £174 (14.5% of £1,200).

You collected £200 VAT. You keep £26 — that's your FRS bonus.

Sounds good. But here's where the pricing trap begins.

The pricing trap: you cannot reclaim VAT on most purchases

Under standard VAT, if you buy £600 of software and services (£500 + £100 VAT), you reclaim the £100. Your real cost is £500.

Under FRS, you cannot reclaim VAT on purchases — with one exception: capital assets costing over £2,000 including VAT.

So that £600 software bill costs you £600. Not £500.

Most FRS businesses know this in theory. But when calculating project costs, they instinctively use the net figure — and quietly absorb the VAT difference as lost margin.

The Limited Cost Trader trap

If your VAT-inclusive spend on goods is less than 2% of your gross turnover (or less than £1,000/year), you are a Limited Cost Trader. Your flat rate is 16.5% — regardless of what business type you are.

Most service businesses qualify as Limited Cost Traders because they spend little on physical goods. At 16.5%, you collect £200 VAT on a £1,000 invoice and pay £198 (16.5% × £1,200). Your FRS bonus is just £2.

At that point, FRS saves you admin time but offers almost no financial benefit — and you're still locked out of reclaiming VAT on purchases.

How to calculate real project cost on FRS

Freelance designer quoting a branding project:

Your time: 18 hours × £45/h = £810.

Real project cost: £1,374

Under standard VAT, you'd reclaim the VAT on those purchases, reducing your cost to roughly £1,298. The £76 difference is the hidden FRS cost on this one project. Over 50 projects a year, that's £3,800 absorbed silently.

What this means for your pricing

On FRS, every VAT-inclusive supplier cost is a real cost with no recovery. When you use a cost calculator, always enter the gross (VAT-inclusive) amount from the invoice — because that's what you actually pay.

The only exception: capital assets over £2,000 including VAT (a laptop, specialist equipment) — for those you can reclaim VAT separately, so use the net figure.

Should you stay on FRS?

FRS stops making sense when:

You can join FRS if VAT-taxable turnover is under £150,000. You must leave if it exceeds £230,000.

The one thing to check today

Open your last three supplier invoices. Are you using the gross or net amount when calculating project costs?

If you're using the net figure and you're on FRS, you're underpricing every project by the VAT you're not reclaiming. On FRS, the gross amount on the invoice *is* your cost. Price accordingly.
