What is the Flat Rate Scheme?
The Flat Rate Scheme (FRS) is an HMRC-approved VAT accounting method designed to make VAT simpler for small businesses. Instead of tracking every penny of VAT you charge on sales and every penny of VAT you pay on purchases, you simply apply one fixed percentage to your total VAT-inclusive turnover — and that is what you pay HMRC each quarter.
The fixed percentage is set by HMRC and varies by trade sector. It is meant to represent the average amount of input VAT a business in that sector would typically reclaim. Rates currently range from 4% for businesses in certain retail categories all the way up to 14.5% for professions such as legal services or computer consultancy. However, if your spending on goods falls below 2% of your turnover (or below £1,000 a year), HMRC classes you as a Limited Cost Trader and a higher rate of 16.5% applies regardless of your sector.
Here is the important part that many small business owners miss: you still charge your customers VAT at the standard rate of 20%. The difference between the 20% you collect and the lower flat rate percentage you hand over to HMRC stays in your business.
For some sectors, this produces a genuine financial saving on top of the reduced admin. For others, particularly service businesses that spend very little on goods, the scheme can cost more than standard VAT accounting once the 16.5% Limited Cost Trader rate kicks in.
The Flat Rate Scheme does not allow you to reclaim input VAT on your day-to-day business purchases. The one exception is capital expenditure items where the total cost, including VAT, is £2,000 or more. If a qualifying capital purchase meets that threshold, you can claim the VAT on that specific item in the usual way.
The scheme is also compatible with cash-based accounting, under the FRS cash-based method, you account for VAT only on invoices you have actually received payment for, rather than invoices you have raised. This can be helpful for businesses that experience gaps between raising an invoice and getting paid.
In summary, the Flat Rate Scheme trades the complexity of transaction-by-transaction VAT calculations for a single straightforward calculation each quarter. Whether that trade-off works in your favour depends entirely on your sector rate, your spending on goods, and the makeup of your business costs.
Who is Eligible to Join the Flat Rate Scheme?
Not every VAT-registered business can join the Flat Rate Scheme. HMRC sets clear conditions you must satisfy before you can apply, and there are ongoing conditions that determine whether you can stay on the scheme.
To join the Flat Rate Scheme, your business must:
- Be registered for VAT with HMRC (either mandatorily or voluntarily)
- Have a VAT-taxable turnover of no more than £150,000 excluding VAT in the next 12 months at the time of application
- Not have left the Flat Rate Scheme in the previous 12 months
- Not have committed a VAT offence (such as VAT fraud or evasion) in the previous 12 months
- Not be closely associated with another business through financial, economic, or organisational ties, HMRC considers such businesses as one and they cannot each join the scheme separately
- Not currently be using a VAT margin scheme (such as the second-hand goods margin scheme), the Tour Operators’ Margin Scheme, or the Capital Goods Scheme for major capital items
- Not be part of a VAT group registration
Once you are on the scheme, you can continue to use it for as long as your total business income, which includes VAT-inclusive turnover from all taxable and exempt supplies, does not exceed £230,000 in any 12-month period. If your income exceeds this figure, or you have reasonable grounds to expect it will exceed £230,000 in the next 30 days alone, you must leave the scheme.
HMRC may allow you to remain on the scheme even after breaching the £230,000 exit threshold, but only if they are satisfied that your total income in the following 12 months will fall below £191,500. You must contact HMRC and seek their approval; you cannot simply stay on the scheme and assume it is fine.
A note on the first-year discount: In your first year of VAT registration, HMRC gives you a 1% reduction on your flat rate percentage. So if your sector rate is 14.5%, you would pay just 13.5% during that initial 12-month period. This discount applies from the date you register for VAT, not from the date you join the Flat Rate Scheme specifically.
You can apply to join the Flat Rate Scheme online through your HMRC VAT account or by completing form VAT600 FRS. HMRC will confirm your start date in writing, the scheme does not apply retrospectively.
How Does This Tool Calculate VAT Under the Flat Rate Scheme?
Our Flat Rate VAT Calculator UK 2026 does the maths so you do not have to. The underlying calculation is straightforward, but getting every figure in the right place matters, especially when you are comparing the Flat Rate Scheme against standard VAT accounting before deciding which is better for your business.
The core formula is:
VAT payable to HMRC = VAT-inclusive turnover × Flat rate percentage
Here is what each input means and how the calculator uses it.
Step 1 – Enter your gross (VAT-inclusive) turnover. This is your total sales revenue including the 20% VAT you have charged your customers. If your net sales for the quarter are £30,000, your VAT-inclusive turnover is £36,000 (£30,000 + 20% VAT). Always use the gross figure, not the net.
Step 2 – Select your business sector. The calculator applies the HMRC flat rate percentage relevant to your trade. These rates are set by HMRC and reviewed periodically. Common examples include 14.5% for computer and IT consultancy, 12% for estate agents, 12.5% for entertainment or journalism, 13% for accounting, and 9% for food manufacturers. If you are unsure of your sector, HMRC publishes a full A-to-Z list in VAT Notice 733.
Step 3 – The calculator works out your FRS VAT payment. Multiplying your gross turnover by your flat rate percentage gives the amount you owe HMRC under the scheme.
Step 4 – Compare against standard VAT accounting. The tool also calculates what you would pay under standard VAT accounting — that is, output VAT (20% of net sales) minus input VAT you have paid on purchases. You can enter your VAT on purchases and any VAT reclaimable on capital assets to get an accurate comparison figure.
A worked example:
Flat Rate Scheme | Standard VAT | |
Net sales | £30,000 | £30,000 |
VAT charged to customers (20%) | £6,000 | £6,000 |
Gross (VAT-inclusive) turnover | £36,000 | — |
Flat rate percentage (14.5%) | £5,220 payable | — |
Input VAT on purchases | Not reclaimable | £1,200 reclaimable |
VAT payable to HMRC | £5,220 | £4,800 |
Retained by business | £780 | — |
In this example, the business pays less under standard VAT, a common outcome for businesses with meaningful purchase costs. The calculator makes this comparison instant so you can see which scheme leaves more money in your pocket before committing either way.
First-year discount: If you are in your first year of VAT registration, tick the relevant box and the calculator will automatically apply the 1% reduction to your flat rate percentage.
Limited Cost Trader check: If your goods spend is less than 2% of your VAT-inclusive turnover (or less than £1,000 per year), you are a Limited Cost Trader. The calculator flags this and applies the 16.5% rate automatically.
What Are the Pros and Cons of the VAT Flat Rate Scheme?
Like any tax scheme, the Flat Rate Scheme has genuine advantages for the right business and real drawbacks for others. Understanding both sides clearly is the only way to make a decision that actually saves you money.
The Advantages
Less admin and simpler record-keeping. Under standard VAT accounting you need to record the VAT on every single purchase and every single sale. Under the Flat Rate Scheme, you only need your gross turnover figure each quarter. This cuts down bookkeeping time significantly, particularly valuable for sole traders and micro business owners who do not have a dedicated finance team.
Predictable cash flow. Because your VAT payment is a fixed percentage of your sales, you always know what proportion of your income is earmarked for HMRC. There are no surprises from fluctuating input VAT reclaims or end-of-quarter reconciliations. This makes cash flow planning much easier.
Potential to keep the difference. If your sector flat rate is meaningfully lower than the effective VAT rate you would pay under standard accounting, you keep the gap. For low-cost service businesses, particularly those in their first year who benefit from the 1% discount, this can translate into a modest but real financial gain each year.
No need to track input VAT on most purchases. Since you cannot reclaim it anyway, you do not need to keep detailed VAT records for your running costs. Fewer records mean a lower risk of HMRC enquiries into input VAT claims.
Cash-based option available. The FRS cash-based method means you only pay VAT on income you have actually received, reducing the risk of paying tax on invoices that remain unpaid.
The Disadvantages
No VAT reclaim on day-to-day purchases. This is the single biggest drawback of the scheme. If you buy significant amounts of stock, materials, or services that carry VAT, you lose the ability to reclaim that VAT. For a business spending £20,000 a year on VATable supplies, that is up to £4,000 of unrecoverable tax each year.
The Limited Cost Trader trap. If you spend very little on goods, you fall into the Limited Cost Trader category and must pay 16.5% of your gross turnover to HMRC. For many service businesses, this rate is higher than what they would pay under standard VAT accounting once their input VAT is taken into account. The scheme was designed to help small businesses, but the 16.5% rate can turn it into a penalty rather than a benefit.
No VAT recovery on capital purchases under £2,000. If you need to buy equipment, tools, or technology below the £2,000 threshold, you cannot reclaim the VAT. Under standard VAT accounting, you could.
It is not suitable if you regularly receive VAT repayments. Businesses that zero-rate a lot of their sales, such as certain exporters or food producers, often have more input VAT than output VAT, meaning HMRC owes them money. The Flat Rate Scheme is not designed for this situation and HMRC may remove businesses that regularly expect repayments.
Sector misclassification risk. If you register under the wrong sector rate, either deliberately or by mistake, HMRC can backdate a correction and charge interest and penalties. Getting your sector right from the start is essential.
Leaving the scheme has a 12-month cooling-off period. Once you leave the Flat Rate Scheme, you cannot rejoin for at least 12 months. If your circumstances change and you realise standard VAT accounting is more expensive, you are locked out of the scheme for the remainder of that period.
FAQs: VAT Flat Rate Scheme
What is the VAT Flat Rate Scheme?
The VAT Flat Rate Scheme is an HMRC-approved method that allows eligible small businesses to pay a single fixed percentage of their gross VAT-inclusive turnover to HMRC each quarter, rather than calculating the difference between the VAT they charge customers and the VAT they pay on purchases. The fixed percentage varies by business sector and is published by HMRC.
Who can use the Flat Rate VAT Calculator UK 2026?
Any UK VAT-registered business that wants to understand what it would pay under the Flat Rate Scheme, or compare the scheme against standard VAT accounting, can use this calculator. It is particularly useful for sole traders, freelancers, contractors, and micro businesses thinking about joining the scheme for the first time in the 2025/26 or 2026/27 tax year.
What is the VAT registration threshold in the UK for 2026?
The mandatory VAT registration threshold remains at £90,000 of taxable turnover in any rolling 12-month period for 2026. If your turnover exceeds this figure, you must register for VAT. Businesses below the threshold can still register voluntarily if they wish to reclaim VAT on purchases.
What is the turnover limit to join the Flat Rate Scheme?
To join the Flat Rate Scheme, your VAT-taxable turnover must be no more than £150,000 excluding VAT in the next 12 months. This is your expected income from VATable supplies and does not include exempt income. If your projections exceed this figure at the point of application, you are not eligible to join.
At what turnover do you have to leave the Flat Rate Scheme?
You must leave the Flat Rate Scheme when your total business income, including VAT-inclusive turnover from all supplies, exceeds £230,000 in any 12-month period, or when you have reasonable grounds to believe it will exceed £230,000 in the next 30 days alone. In some cases, HMRC may allow you to stay on if they are satisfied your income will not exceed £191,500 in the following 12 months.
What flat rate VAT percentages apply in 2026?
HMRC’s flat rate percentages for 2026 remain unchanged from the rates introduced in previous years, ranging from around 4% for certain retailers up to 14.5% for professions such as IT consultancy, accountancy, or legal services. A flat rate of 16.5% applies to businesses classified as Limited Cost Traders. Always verify your current rate against HMRC’s official A-to-Z list in VAT Notice 733, as rates can be updated.
What is a Limited Cost Trader and how does it affect my flat rate?
A Limited Cost Trader is a business whose spending on goods is either less than 2% of their VAT-inclusive turnover in a quarter, or less than £1,000 per year. If you fall into this category, you must use a flat rate of 16.5% regardless of your business sector. This rule was introduced by HMRC in 2017 to prevent service businesses with very low costs from gaining an unfair advantage from the scheme. Many consultants, freelancers, and IT contractors are affected by this rule.
Can I reclaim VAT on purchases under the Flat Rate Scheme?
Generally, no. One of the core trade-offs of the Flat Rate Scheme is that you cannot reclaim input VAT on your everyday business purchases. The one exception is capital expenditure items where the total cost, including VAT, is £2,000 or more. If a single capital purchase meets or exceeds this threshold, you can reclaim the VAT on that item in addition to paying your flat rate percentage on turnover.
How do I calculate my VAT under the Flat Rate Scheme?
The calculation is: gross (VAT-inclusive) turnover × flat rate percentage = VAT payable to HMRC. For example, if your gross turnover for the quarter is £24,000 and your flat rate is 14.5%, you would pay HMRC £3,480. You still charge your customers 20% VAT on your invoices, the flat rate only changes how much of that collected VAT you hand over to HMRC.
Is the Flat Rate Scheme better than standard VAT accounting?
It depends on your business. The Flat Rate Scheme tends to benefit service-based businesses with low purchase costs and a sector flat rate below the effective VAT rate they would pay under standard accounting. It tends to be less beneficial, or actively more expensive, for businesses with significant VATable purchases, businesses classified as Limited Cost Traders, and businesses that regularly generate VAT repayments from HMRC. Use our Flat Rate VAT Calculator to compare both options with your own figures before deciding.
Do I still charge my customers 20% VAT on the Flat Rate Scheme?
Yes. Being on the Flat Rate Scheme does not change how you invoice your customers. You still charge VAT at the standard rate of 20% (or the reduced or zero rate where applicable). The Flat Rate Scheme only changes the method you use to calculate how much VAT you pay to HMRC, it does not affect the VAT your customers see on their invoices.
Is there a discount in the first year of the Flat Rate Scheme?
Yes. HMRC gives new VAT registrants a 1% reduction on their flat rate percentage for the first year of VAT registration. So if your sector rate is 14.5%, you pay just 13.5% during your first 12 months as a VAT-registered business. This discount applies from the date of your VAT registration, not from the date you specifically apply to join the Flat Rate Scheme.
Can I leave the Flat Rate Scheme whenever I want?
You can leave the Flat Rate Scheme voluntarily at any time by notifying HMRC in writing. However, once you leave — whether voluntarily or because you have exceeded the turnover threshold, you cannot rejoin for at least 12 months. It is worth considering this restriction carefully before leaving, as you may find you want to return sooner than expected.
Is the Flat Rate Scheme compatible with Making Tax Digital (MTD)?
Yes. The Flat Rate Scheme is fully compatible with Making Tax Digital for VAT, which has been mandatory for all VAT-registered businesses since April 2022. You must keep digital records and submit your VAT returns through MTD-compatible software regardless of which VAT scheme you use. From April 2026, MTD for Income Tax will also apply to sole traders and landlords with qualifying income.
How do I apply to join the Flat Rate Scheme?
You can apply to join the Flat Rate Scheme online through your Government Gateway VAT account, or by completing and submitting form VAT600 FRS by post. If you are registering for VAT for the first time, you can apply to join the Flat Rate Scheme at the same time as your VAT registration. HMRC will confirm your start date in writing, the scheme does not apply retrospectively to periods before HMRC approves your application.
