VAT Schemes for Small Businesses: Which One Actually Suits You?
Flat Rate, Cash Accounting or standard? The scheme you use changes how much VAT you pay and when you pay it. Here is how the main options compare for a UK small business.
Once you are VAT registered, you can often choose how you account for VAT rather than accepting the standard method. The Flat Rate Scheme pays HMRC a fixed percentage of your turnover, Cash Accounting lets you pay only when customers have actually paid you, and Annual Accounting reduces you to one return a year with instalments. Each suits a different kind of business, and picking the wrong one quietly costs money every quarter.
The short version
Standard VAT accounting means you pay on invoices raised, whether or not the customer has paid you yet.
Cash Accounting is available if your VAT taxable turnover is £1.35 million or less, and it ties VAT to money actually received.
The Flat Rate Scheme is open to businesses with VAT turnover of £150,000 or less and swaps input tax recovery for a simpler fixed percentage.
Annual Accounting cuts the paperwork to one return a year with payments on account through the year.
You can combine some of them, but not all, so the right answer depends on how you invoice and how much VAT you reclaim.
How does standard VAT accounting work?
Under the standard method you account for VAT on the date of the invoice, not the date of payment. You add up the VAT you charged customers in the quarter, subtract the VAT you paid on business purchases, and pay HMRC the difference. If you paid more than you charged, you reclaim the balance. The current rates are 20 per cent standard, 5 per cent reduced and zero for certain goods and services, as set out in the GOV.UK guidance on charging and reclaiming VAT.
For a business paid quickly that buys a lot of VAT bearing stock, standard accounting is the sensible default. The problem arises when customers pay slowly. You can end up handing VAT to HMRC on an invoice that has not been settled, which is a real squeeze for trades and contractors on longer payment terms.
When is Cash Accounting the better option?
Cash Accounting solves exactly that problem. You pay VAT on sales when your customer pays you, and you reclaim VAT on purchases when you have paid your supplier. Nothing else changes, and your returns are still quarterly. To join, your VAT taxable turnover must be £1.35 million or less, which covers the great majority of the small businesses our taxation team looks after across Widnes and Cheshire.
The trade off is on the purchase side. Because you only reclaim when you have paid, a business buying heavily on credit gives up the timing advantage it had. It also does not help if customers already pay on the spot, as retail and hospitality find. Where it shines is invoicing commercial customers and waiting sixty or ninety days for the money.
Cash Accounting has a quiet benefit that owners often overlook. If a customer never pays, you never account for the VAT in the first place, so there is no bad debt relief claim to make later. Under the standard method you have to pay the VAT and then reclaim it once the debt is six months overdue.
What about the Flat Rate Scheme?
The Flat Rate Scheme takes a different approach. Instead of tracking input and output tax separately, you pay HMRC a fixed percentage of your gross turnover, keep the difference between that and the VAT you charged, and give up the right to reclaim VAT on most purchases. The percentage depends on your trade sector. You can join if your VAT turnover is £150,000 or less, excluding VAT, and the GOV.UK overview of the Flat Rate Scheme sets out the eligibility rules.
The appeal is simplicity, and for a service business with very few costs it can also work out cheaper. A consultant with a laptop and little else buys almost nothing with VAT on it, so surrendering input tax recovery costs very little. The scheme becomes a poor choice the moment you spend meaningfully on materials, stock, fuel or subcontractors, because that reclaimable VAT simply disappears.
There is also the limited cost business rule, which applies a higher percentage to businesses that spend very little on goods. It exists to stop the scheme being used as an automatic saving by labour only businesses, so the arithmetic needs checking rather than assuming. One exception is worth knowing: you can still reclaim VAT on a single capital asset costing more than £2,000 including VAT.
| Scheme | Best suited to | Main limit | Main trade off |
| Standard accounting | Businesses paid quickly with significant VAT on purchases | None | VAT due on unpaid invoices |
| Cash Accounting | Businesses invoicing on credit terms | VAT turnover £1.35m or less | Input tax delayed until you pay suppliers |
| Flat Rate Scheme | Service businesses with very low costs | VAT turnover £150,000 or less | No input tax recovery on most purchases |
| Annual Accounting | Businesses wanting predictable payments | VAT turnover £1.35m or less | Instalments based on last year, one return a year |
Thresholds are the current published figures. Eligibility also depends on your compliance history and trade sector.
Does Annual Accounting reduce the workload?
Annual Accounting changes the rhythm rather than the arithmetic. You submit one VAT return a year instead of four and make interim payments through the year based on your previous liability, with a balancing payment when the return is filed. For a business with steady, predictable turnover it makes cash flow planning easier and cuts the administrative noise considerably.
It suits businesses that dislike the quarterly cycle and can budget comfortably. It suits growing businesses less well, because instalments based on last year can leave a large balancing payment. It is also unhelpful if you regularly reclaim VAT, since you wait a full year for it. Our accounting team models the cash flow both ways before recommending it.
How do you choose between them?
1Look at how you get paid
If customers pay on invoice terms rather than immediately, Cash Accounting is usually the first thing to consider.
2Add up the VAT on your purchases
High material, stock or fuel costs make the Flat Rate Scheme expensive. Low costs make it attractive.
3Check the thresholds against your turnover
The Flat Rate limit is much lower than the Cash Accounting one, so growth can take you out of a scheme you have settled into.
4Think about how predictable your year is
Annual Accounting rewards steady trading and punishes rapid growth with a large balancing payment.
5Model it on last year’s real figures
The only reliable test is running your own numbers through each method.
You can combine Cash Accounting with Annual Accounting, and the Flat Rate Scheme has its own built in cash basis option, but the schemes are not all interchangeable. Note too that all VAT registered businesses are now within Making Tax Digital for VAT, so whichever scheme you use, your records need to be digital and your returns filed through compatible software. Keeping them that way is part of what our bookkeeping service does month to month.
Mistakes we see most often
Staying on the Flat Rate Scheme after the business has grown into buying materials, so reclaimable VAT is lost every quarter.
Joining the Flat Rate Scheme without checking the limited cost business rule, then finding the percentage is higher than expected.
Choosing Cash Accounting when customers already pay immediately, which gives up input tax timing for no benefit.
Using Annual Accounting through a growth year and being caught out by the balancing payment.
Assuming the choice is permanent. Each scheme has its own exit timing, and it is worth reviewing whenever the shape of the business changes.
Frequently Asked Questions
Can I be on more than one VAT scheme at once?
Some combine and some do not. Cash Accounting and Annual Accounting can be used together, which is a common pairing for smaller businesses. The Flat Rate Scheme includes its own cash based turnover method, so you do not add Cash Accounting on top. Speak to us and we will confirm what is possible for your setup.
Will the Flat Rate Scheme always save me money?
No, and that is the biggest misunderstanding about it. It saves money only where your purchases carry very little VAT. A trade business buying materials, or a retailer buying stock, will usually pay more overall because the input tax it would have reclaimed is simply lost.
What happens if my turnover grows past a scheme threshold?
You have to leave the scheme, and each one has its own exit rules and timing. The Flat Rate Scheme has a lower limit than the others, so growing businesses tend to hit that one first. It is worth checking your position annually rather than waiting for a letter from HMRC.
Do these schemes affect Making Tax Digital?
All VAT registered businesses are now signed up for Making Tax Digital for VAT, whichever scheme they use. Your records must be kept digitally and returns submitted through compatible software. The scheme you choose changes the figures, not the filing method.
Can I reclaim VAT on equipment under the Flat Rate Scheme?
Generally you cannot reclaim VAT on purchases, but there is an exception for capital expenditure goods costing more than £2,000 including VAT in a single purchase. That makes a significant equipment buy worth planning carefully if you are on the scheme.
