Your summary

Standard VAT saves you£380a year

Under standard accounting you would pay HMRC £11,500. On the Flat Rate Scheme at 16.5% you would pay £11,880. Your goods spending is below the limited cost test, so the 16.5% rate applies instead of the 14.5% rate for your trade.

You count as a limited cost trader

Your goods are below £1,440, so you must use 16.5%. If they were above it, your 14.5% trade rate would apply and you would pay £10,440. Only goods count: not services, capital items, food, fuel or vehicle costs.

Worth knowing

Before you switch scheme.

Flat rate would only win with costs below £720

At these sales and a 16.5% flat rate, the two schemes cost the same when your costs with VAT are £720 a year.

Simpler records, but check your margin

The flat rate saves working out VAT on every purchase, but the VAT you keep is taxable income. If you buy a lot, standard accounting usually works out cheaper.

THE FLAT RATE SCHEME GUIDE

Is the VAT Flat Rate Scheme worth it?

The Flat Rate Scheme lets a small business pay HMRC a fixed percentage of its turnover instead of working out VAT on every sale and purchase. For some trades it saves money as well as time. For many freelancers it now costs more than standard VAT. This guide explains how it works, the limited cost trader test that catches most people, and how to decide.

1In brief

The short answer

On the Flat Rate Scheme you still charge customers 20% VAT, but instead of paying HMRC the VAT you charged minus the VAT you paid on costs, you pay a flat percentage of your VAT-inclusive turnover. The percentage depends on your trade, from 4% to 14.5%.

The catch is the limited cost trader rule. If you spend little on goods, you must use 16.5% whatever your trade. At 16.5%, the scheme takes almost all the VAT you charge, so it rarely saves money.

  4. Flat rate VAT£72,000 × 14.5%£10,440

The flat rate applies to the VAT-inclusive figure, not the price before VAT. That is easy to get wrong when you first estimate what the scheme is worth.

3Your percentage

Flat rates by trade

HMRC sets a percentage for each type of business. You use the one that best describes your main activity. A selection is below; the calculator lists them all.

Selected flat rates (unchanged since April 2022)
TradeFlat rate
Retailing food, confectionery, tobacco, newspapers or children's clothing4%
Pubs6.5%
Retailing not listed elsewhere7.5%
General building or construction services9.5%
Transport or storage, including couriers and taxis10%
Photography11%
Any other activity not listed elsewhere12%
Catering, including restaurants and takeaways12.5%
Hairdressing or other beauty treatment13%
Management consultancy14%
Accountancy, IT consultancy, legal, labour-only building14.5%
Limited cost trader (any trade)16.5%

Lower rates go to trades that usually spend a lot on stock or materials, because they would reclaim more VAT under standard accounting. Higher rates go to service trades with few costs.

4The key test

The limited cost trader test

Since April 2017 you must use the 16.5% rate if you are a limited cost business. You are one if the goods you buy for the business, including VAT, are either:

  • less than 2% of your VAT-inclusive turnover, or
  • more than 2% but less than £1,000 a year (£250 a quarter).

Only goods count, and only goods used wholly for the business. These do not count:

  • services of any kind, such as software subscriptions, phone contracts, accountancy, rent or advertising;
  • capital items, such as a laptop, camera or machine;
  • food or drink for you or your staff;
  • vehicles, vehicle parts and fuel, unless you are in the transport business;
  • goods for resale, leasing or hire that are not your main business, and gifts or promotional items.

Why most freelancers fail it

A consultant or developer typically buys software and services, not goods. Even with thousands of pounds of costs, their goods may be close to zero, so they must use 16.5%. You have to check the test every VAT period, and you cannot buy goods you do not need just to pass it.

Who gains and who loses

The same scheme gives very different results depending on trade and costs. All figures are for a full year.

“VAT kept” is not the same as the saving: a business on standard accounting would also reclaim VAT on its costs. The builder keeps £6,880 of the VAT it charges but gives up £5,000 of VAT it could have reclaimed, so it is £1,880 better off.

6A common trap

What counts as turnover

The flat rate applies to your whole VAT-inclusive turnover, including zero-rated and exempt sales. Under standard accounting those sales carry no VAT at all, so a business with a mix of sales can lose out.

Flat rate turnover
£60,000

£7,200

£9,500
Result

Flat rate turnover
£80,000
Flat rate VAT at 12%
£9,600
Standard VAT
£9,500
Result
Standard saves £100

Sales to customers outside the UK, some books and children’s clothes are typical zero-rated sales that catch people out. If a large share of your sales are zero-rated or exempt, the scheme is unlikely to help.

7Big purchases

Capital purchases

On the Flat Rate Scheme you cannot reclaim VAT on normal costs, but you can reclaim it on a single purchase of capital goods costing £2,000 or more including VAT, such as a computer, a van or a piece of machinery. You claim it on your VAT return in the usual way.

A £2,400 computer carries £400 of VAT, which you reclaim on either scheme. The rule applies to a single purchase: several smaller items bought together do not count unless they are invoiced as one item, and services do not count however large.

8New registrations

The first-year discount

If you join the scheme in your first year of VAT registration, you can take 1% off your flat rate until the day before the first anniversary of your registration. A limited cost trader pays 15.5% instead of 16.5%.

The discount is small, but for some freelancers it is the only year the scheme saves money. In the IT example above, 16.5% costs £380 more than standard accounting, while 15.5% saves £340. Diary the anniversary: once the discount ends, compare again and leave the scheme if it no longer pays.

9Eligibility

Joining and leaving

  1. To joinExpected taxable sales of £150,000 or less

    Before VAT, over the next 12 months. Apply online or when you register for VAT.

  2. While on itCheck the limited cost test every return

    Use 16.5% for any period in which you fail it, and your trade rate in periods you pass.

  3. Must leaveIncome including VAT over £230,000

    In the last 12 months, or expected in the next 30 days alone.

  4. After leavingWait 12 months to rejoin

    You can leave voluntarily at any time, but you cannot come back for a year.

You cannot use the scheme if you are in the VAT margin scheme for second-hand goods or the capital goods scheme, or if you are closely associated with another business. HMRC’s Notice 733 lists every condition.

10Income Tax

Income Tax on the VAT you keep

The difference between the VAT you charge and the flat rate VAT you pay is extra income for your business. It is added to your taxable profits.

For the builder in the examples, the £1,880 saving is taxed like any other profit: a sole trader paying basic-rate tax and Class 4 National Insurance keeps about £1,391 of it after 20% Income Tax and 6% National Insurance. Remember this when you compare schemes: the real saving is after tax.

11Choosing

How to decide

  1. Work out whether you pass the limited cost test. If you do not, compare at 16.5% (15.5% in year one).
  2. Add up a typical year’s costs that carry VAT, including the VAT.
  3. Compare the VAT payable under each scheme using the calculator above.
  4. Allow for the Income Tax on any gain and the time you save on bookkeeping.
  5. Recheck every year, or sooner if your costs or sales mix change.

As a rule of thumb, the scheme suits trades with a low flat rate and steady spending on goods, such as builders, shops and hairdressers. It rarely suits consultants, developers and other professionals after the first year.

12Filing

Your VAT return on the scheme

On the Flat Rate Scheme your VAT return is simpler than under standard accounting, but a few boxes work differently:

  • Box 1 shows the flat rate VAT: your flat rate percentage times your VAT-inclusive turnover for the period.
  • Box 4 is usually zero, unless you are reclaiming VAT on a capital purchase of £2,000 or more.
  • Box 6 shows your flat rate turnover including VAT, not the net figure most businesses use.

You still need to keep a record of your sales, the flat rate you used for each period and how you worked out the limited cost test. Keep your purchase invoices too: you need them for capital purchases and to show the goods figure behind the test.

13Planning ahead

Year one and beyond

The scheme can look attractive when you first register and less so a year later. For the IT contractor in the examples, with £60,000 of sales, £3,000 of costs and £600 of goods:

First year (15.5%)
Flat rate VAT
£11,160
Standard VAT
£11,500
Result
Flat rate saves £340
Later years (16.5%)
Flat rate VAT
£11,880
Standard VAT
£11,500
Result
Standard saves £380

You can ask HMRC to take you off the scheme at any time, and the change normally applies from the start of a VAT period. Set a reminder for the first anniversary of your registration, rerun the comparison, and move to standard accounting if it now costs less. Make sure your invoicing software is ready to record VAT on purchases from the day you switch.

Questions

Frequently asked

How does the Flat Rate Scheme work?

You charge customers 20% VAT as normal, but pay HMRC a fixed percentage of your VAT-inclusive turnover instead of the difference between VAT charged and VAT on costs.

What is a limited cost trader?

A business whose spending on goods is less than 2% of its VAT-inclusive turnover, or less than £1,000 a year. It must use the 16.5% flat rate.

Who can join the Flat Rate Scheme?

VAT-registered businesses that expect taxable sales of £150,000 or less, before VAT, in the next 12 months.

Can I reclaim VAT on the Flat Rate Scheme?

Only on single capital purchases of £2,000 or more including VAT. You cannot reclaim VAT on normal costs.

Is the VAT I keep on the Flat Rate Scheme taxable?

Yes. The difference between the VAT you charge and the flat rate VAT you pay is part of your taxable profit.

Do I still charge 20% VAT on the Flat Rate Scheme?

Yes. Your invoices look exactly the same. Only the amount you pay HMRC changes.

Can I reclaim VAT on my phone and software?

No. On the Flat Rate Scheme you cannot reclaim VAT on costs, except on single capital purchases of £2,000 or more.

Which trade do I choose if I do several things?

The one that makes up the largest share of your turnover. Keep a note of why you chose it in case HMRC asks.

Does the scheme work with Making Tax Digital?

Yes. You still keep digital records and file returns through compatible software.

Can I use the scheme with cash accounting?

The Flat Rate Scheme has its own cash-based turnover option, so you can pay flat rate VAT on money received rather than on invoices. You cannot also join the separate Cash Accounting Scheme.

Is the Flat Rate Scheme the same for limited companies?

Yes. The rates, the limited cost test and the turnover limits are the same whether you trade as a sole trader, a partnership or a limited company.

What if my goods spending changes during the year?

Apply the test separately to each VAT return. In a quarter where you buy enough goods, use your trade rate; in a quarter where you do not, use 16.5%.

Can I backdate joining the scheme?

Usually only from the start of your current VAT period, though HMRC can sometimes agree an earlier date. Ask when you apply.
