f you’re VAT registered (or about to be), one of the most common questions is whether you should use the VAT Flat Rate Scheme (FRS) or stick with Standard VAT accounting. The answer depends on your costs, customers, and how much admin you want.
This guide explains the difference in plain English and gives you a simple way to decide.

What’s the difference between Flat Rate VAT and Standard VAT?
Standard VAT (the “normal” method)
With Standard VAT accounting, you:
- charge VAT on your sales (output VAT)
- reclaim VAT on business purchases (input VAT), where allowed
- pay HMRC the difference through your VAT return (net VAT)
HMRC confirms you can reclaim VAT on items you buy for your business if you’re VAT registered (and only the business proportion if there’s personal use).
VAT Flat Rate Scheme (FRS)
With the Flat Rate Scheme:
- you still charge customers the normal VAT rate for what you sell
- but you pay HMRC a fixed percentage of your VAT-inclusive turnover (rather than reclaiming input VAT in the usual way)
HMRC describes FRS as a simpler method of working out VAT due and explains you must include VAT in your flat rate turnover calculation.
Who can join the VAT Flat Rate Scheme?
You can join FRS if:
- you’re VAT registered, and
- you expect your VAT taxable turnover to be £150,000 or less (excluding VAT) in the next 12 months.
(There are additional exclusions, like having left the scheme recently or being closely associated with another business.)
The big “gotcha”: the Limited Cost Business rule (16.5%)
If you spend only a small amount on goods, HMRC class you as a limited cost business and you must use a higher flat rate of 16.5%.
HMRC defines a limited cost business as one where goods cost less than 2% of turnover or £1,000 a year (if costs are more than 2%), and confirms the 16.5% rate applies.
This is why many service-based businesses don’t benefit from FRS anymore—they often fall into the 16.5% category.
Can you reclaim VAT on purchases under the Flat Rate Scheme?
Generally no—that’s part of the trade-off. HMRC states that under FRS you cannot reclaim VAT on purchases, except for certain capital assets over £2,000.
So if you have significant VATable costs, Standard VAT often wins.
Flat Rate vs Standard VAT: quick pros and cons
Flat Rate Scheme can be better if…
- your VATable costs are low
- you’re not a limited cost business (not on 16.5%)
- you want simpler VAT calculations and more predictable payments
- you mainly sell standard-rated services and want to reduce admin (FRS was designed to simplify record keeping)
Standard VAT can be better if…
- you buy a lot of VATable goods/services (so you can reclaim more input VAT)
- you regularly reclaim VAT (FRS is noted as unsuitable where you regularly receive VAT repayments)
- your sales include a lot of zero-rated or exempt income (FRS applies the flat rate to these too, which can make you worse off)
A simple example (to see which is better)
Let’s say your business invoices £10,000 + VAT in a quarter.
- Your VAT-inclusive sales = £12,000
Flat Rate (example rate 12%)
- Pay HMRC: £12,000 × 12% = £1,440
Limited Cost Business (16.5%)
- Pay HMRC: £12,000 × 16.5% = £1,980
Standard VAT (example costs)
- Output VAT collected: £2,000
- Input VAT on expenses reclaimed: £600
- Pay HMRC: £2,000 − £600 = £1,400
In this example:
- Standard VAT beats 12% FRS by a little (£1,400 vs £1,440)
- Standard VAT beats 16.5% FRS by a lot (£1,400 vs £1,980)
The takeaway: the “best” scheme depends on your rate and your reclaimable VAT.
So… which VAT scheme is best for your business?
Flat Rate is often best when:
- you’re under the £150k threshold
- you’re not limited cost
- your reclaimable VAT is small
- you value simplicity
Standard VAT is often best when:
- you have meaningful VATable expenses
- you buy stock/materials or use VATable subcontractors/services
- you’re near limited-cost territory
- you need accurate VAT reclaim to protect cashflow
Quick decision checklist (60 seconds)
Answer these:
- Do you expect taxable turnover (ex VAT) to stay ≤ £150,000?
- Would you be classed as limited cost (goods under 2% of turnover or £1,000 rule)?
- Do you reclaim a meaningful amount of VAT on purchases?
- Do you sell a lot of zero-rated/exempt items (which can make FRS less attractive)?
If you want, we can run the numbers quickly and tell you which option is likely to be better based on your last 2–4 VAT quarters.
