The VAT Flat Rate Scheme allows eligible small businesses to calculate the VAT paid to HMRC by applying a fixed percentage to VAT-inclusive turnover. The business continues charging customers VAT at the normal rate, but it does not usually deduct the VAT paid on individual purchases when preparing its return.

The scheme can simplify VAT calculations, but it does not automatically reduce the amount a business pays. The result depends on the applicable sector percentage, the amount of VAT normally recoverable on purchases and whether the business is treated as a limited cost business.

A comparison should be completed using the business’s actual sales and purchase records before joining or remaining in the scheme. A percentage that initially appears favourable can become more expensive than ordinary VAT accounting once lost input-tax recovery and the limited cost rules are considered.

How the VAT Flat Rate Scheme works

Under standard VAT accounting, a business generally calculates the difference between VAT charged to customers and eligible VAT incurred on business purchases. Under the VAT Flat Rate Scheme, the business instead applies its flat rate percentage to the turnover included within the scheme.

The percentage is applied to VAT-inclusive turnover. This means a business invoicing £10,000 plus £2,000 VAT normally applies its flat rate percentage to £12,000 rather than the £10,000 net sale.

The business still issues ordinary VAT invoices showing the correct rate of VAT. Customers do not pay the flat rate percentage, and the scheme does not change the VAT rate charged on the underlying supply.

The difference between the VAT collected and the amount calculated under the scheme remains within the business. However, that difference partly compensates for the VAT on ordinary purchases that the business can no longer reclaim separately.

HMRC’s VAT Flat Rate Scheme guidance explains the basic operation, eligibility conditions and restriction on recovering purchase VAT.

Who can join the VAT Flat Rate Scheme

A VAT-registered business can generally apply to join where it expects its VAT-taxable turnover, excluding VAT, to be £150,000 or less during the next 12 months.

Taxable turnover includes standard-rated, reduced-rated and zero-rated supplies. Exempt income is not included when assessing the £150,000 joining threshold.

Some businesses cannot join even where turnover is below the threshold. Restrictions can apply where the business left the scheme during the previous 12 months, committed certain VAT offences, was recently connected with a VAT group or division, uses certain other VAT schemes or is closely associated with another business.

Joining is optional. A business does not have to use the scheme simply because it is eligible, and VAT registration does not automatically place a business within it.

HMRC’s guidance on who can join the Flat Rate Scheme provides the current threshold and exclusions.

Choosing the correct flat rate percentage

Businesses that are not limited cost businesses normally use the percentage assigned to the sector that most closely describes their expected activity for the coming year.

Current examples include 14.5 per cent for accountancy or bookkeeping, 11 per cent for advertising and 12 per cent for an activity not listed elsewhere. The percentage should not be selected solely because another description produces a lower VAT payment.

Where a business carries on several activities, it normally uses the percentage applying to the activity that generates the greatest turnover. It does not usually split its turnover across several sector rates.

The sector should be reviewed where the business changes direction or the balance of its activities changes materially. The bookkeeping records should make it possible to demonstrate why a particular trade classification was selected.

HMRC publishes the current flat rates for different types of business, together with the rules for limited cost businesses.

The one per cent first-year reduction

A business in its first year of VAT registration can generally reduce its normal flat rate percentage by one percentage point. The reduction runs for the first 12 months following VAT registration, not for 12 months from the date the business later joins the Flat Rate Scheme.

For example, a business with a normal sector rate of 12 per cent may use 11 per cent during the qualifying portion of its first VAT-registration year.

A limited cost business with a 16.5 per cent rate can generally use 15.5 per cent while the first-year reduction remains available.

The reduction may be available for only a short period where the business joins the scheme several months after registering for VAT. The bookkeeping or VAT software should therefore record the registration anniversary and apply the standard percentage from the correct date.

What is a limited cost business?

A limited cost business must use a flat rate percentage of 16.5 per cent regardless of the sector percentage that would otherwise apply.

The test is completed using the relevant goods purchased during each VAT Return period. A business is treated as limited cost where expenditure on qualifying goods is less than 2 per cent of its flat rate turnover.

A business is also limited cost where expenditure exceeds 2 per cent but remains below £1,000 for a full year. For a quarterly VAT period, the corresponding minimum is normally £250.

This means both parts of the test matter. Spending more than £250 during a quarter does not prevent limited cost status where the goods still represent less than 2 per cent of turnover.

The test is applied for each VAT period. A business can use its ordinary sector rate in one quarter and the 16.5 per cent limited cost rate in another where qualifying goods expenditure moves above and below the thresholds.

Which purchases count as goods?

The limited cost calculation uses a restricted definition of goods. The items must be used exclusively for the purposes of the business and must not fall within one of the excluded categories.

Potential qualifying goods can include stock for resale, raw materials incorporated into products and certain consumable items used in delivering the business’s services.

Services do not count. Accountancy fees, software subscriptions, advertising, telephone services, rent and subcontractor labour therefore do not help a business pass the limited cost test.

Capital expenditure goods are excluded from the limited cost calculation. Cars, vans, parts and fuel are also generally excluded unless the business operates within a relevant transport activity.

Food and drink for the business or its staff normally do not count. Promotional gifts, goods intended for resale and mixed-use purchases may require careful consideration under HMRC’s detailed rules.

The bookkeeping should separate qualifying goods from ordinary services and excluded purchases. A total expenses figure from the profit and loss account is not sufficient to complete the limited cost test correctly.

Why many service businesses are limited cost

Consultants, agencies, contractors and other service businesses may have substantial expenses while purchasing very few qualifying goods. Their largest costs are often software, professional services, travel, premises and subcontractors, none of which normally count as goods for this test.

A business can therefore spend thousands of pounds during a quarter and still be classified as limited cost. The relevant question is not whether the business has low expenses generally, but whether it purchases enough qualifying goods.

The 16.5 per cent rate leaves only a small difference between the VAT collected from customers and the flat rate paid to HMRC. On a VAT-inclusive sale of £120, the flat rate liability is £19.80, compared with £20 of VAT charged to the customer.

The business retains only 20 pence from that transaction before considering the purchase VAT it can no longer recover. For many limited cost businesses, ordinary VAT accounting may therefore produce a better result.

Calculating a Flat Rate Scheme return

Suppose a business has net taxable sales of £20,000 and charges £4,000 VAT. Its VAT-inclusive turnover is £24,000.

If its applicable flat rate is 12 per cent, the Flat Rate Scheme liability would be £2,880. The business collected £4,000 VAT from customers and would retain the £1,120 difference, but it would not normally reclaim VAT on ordinary purchases separately.

If the same business is limited cost, the 16.5 per cent rate produces a liability of £3,960. It retains only £40 of the £4,000 VAT collected before accounting for the loss of input-tax recovery.

Under standard VAT accounting, the business would pay the £4,000 output tax less eligible VAT on its purchases. If recoverable input tax exceeded £40, ordinary accounting would produce a lower liability than the limited cost rate in this simplified example.

The true comparison must use all relevant turnover, purchase VAT, adjustments, bad debts and unusual transactions for the periods being reviewed.

Turnover included in the Flat Rate Scheme

The Flat Rate Scheme calculation can include more than ordinary standard-rated sales. The business may need to include zero-rated supplies, reduced-rated supplies and certain exempt income within its flat rate turnover.

This can make the scheme unattractive for businesses receiving significant exempt or zero-rated income because the flat percentage may apply even though little or no output VAT was charged on the underlying supply.

Sales of some capital assets, reverse-charge transactions and other amounts may be dealt with outside or alongside the standard flat rate calculation.

The business should not calculate the return simply by applying a percentage to the amount shown in one sales category. The accounting records need to identify each relevant type of turnover and any transactions receiving separate treatment.

Recovering VAT on purchases

A business using the Flat Rate Scheme does not normally reclaim VAT on ordinary goods and services. The flat rate percentages already contain an assumed allowance for purchase VAT.

This restriction can make the scheme unsuitable for businesses with substantial VAT-bearing costs. Retailers, trades, manufacturers and growing businesses making significant purchases may recover more under standard VAT accounting.

The business must still retain purchase invoices even where VAT is not reclaimed. The invoices support the expense, the accounts, the limited cost calculation and any capital expenditure claim.

VAT on certain transactions, including reverse-charge supplies and qualifying capital expenditure goods, may be accounted for separately under the applicable rules.

Capital assets costing £2,000 or more

A business using the Flat Rate Scheme may be able to reclaim VAT on a single purchase of capital expenditure goods costing at least £2,000 including VAT.

The purchase must be a single supply of capital goods. Several separate items costing less than £2,000 each cannot normally be grouped together merely because they appear on connected invoices.

Services do not qualify for this exception. Building work, installation services and other service-based expenditure cannot generally be treated as capital expenditure goods solely because the total exceeds £2,000.

Examples of potentially qualifying goods can include a van, computer or machine purchased for continuing use in the business. Consumable items, goods for resale and items intended to be used up do not qualify.

The supplier invoice, payment evidence and asset records should be retained. The accounting system should separate the asset cost, recoverable VAT and any finance liability.

Selling a capital asset

Additional VAT consequences can arise when a business sells an asset on which it reclaimed input VAT separately while using the Flat Rate Scheme.

The sale may need to be accounted for outside the flat rate calculation, with the normal VAT due reported separately. The sales value may also need to appear in the appropriate VAT Return boxes.

The fixed asset register should identify whether VAT was reclaimed when the item was acquired. Without that information, the business may apply the wrong treatment when the asset is eventually sold or traded in.

Where the business leaves the scheme while still owning an asset on which VAT was recovered separately, special rules can also apply. Material asset disposals should be reviewed with an appropriately qualified VAT adviser.

Flat Rate Scheme cash-based turnover

The Flat Rate Scheme contains its own cash-based turnover method. Businesses using it generally account for relevant turnover according to payments received rather than invoice dates.

This is not the same as joining the separate VAT Cash Accounting Scheme. A business cannot use the Flat Rate Scheme and the ordinary Cash Accounting Scheme at the same time.

The selected turnover method should be applied consistently. Customer receipts, refunds, credit notes and bad debts need to be handled according to the method used.

Bookkeeping should preserve the invoice and payment information even where VAT is calculated from cash received. This allows the business to monitor unpaid customers and prepare its annual accounts correctly.

Flat Rate Scheme and the VAT domestic reverse charge

Reverse-charge transactions require separate attention because the Flat Rate Scheme does not remove the customer’s obligation to account for VAT under a domestic reverse charge.

Construction businesses may receive or make supplies covered by the domestic reverse charge for building and construction services. The reverse-charge VAT is generally dealt with outside the ordinary flat rate turnover calculation.

The accounting software must use codes suitable for both the Flat Rate Scheme and the reverse charge. Applying an ordinary flat rate code to every construction invoice can produce incorrect VAT Return figures.

The business should reconcile its VAT control accounts before submission and retain evidence supporting the treatment used. Our guide to VAT adjustments in Xero explains why corrections should remain supported and visible.

Comparing the Flat Rate Scheme with standard VAT accounting

A meaningful comparison should use actual figures from several recent VAT periods. One unusually high or low quarter may not represent the business’s normal activity.

The calculation should compare the Flat Rate Scheme liability with output VAT less recoverable input VAT under standard accounting. It should also consider the one per cent first-year reduction, limited cost periods and purchases that receive special treatment.

Future plans matter as well. A service business with low costs today may be preparing to employ staff, move premises or purchase substantial equipment. A growing trades business may expect materials and subcontractor costs to change significantly.

The administrative saving should not be exaggerated. A business still needs to issue correct VAT invoices, maintain digital VAT records, reconcile sales and purchases and submit its return through Making Tax Digital-compatible software.

Professional advice should be obtained before changing schemes where partial exemption, international transactions, property income or substantial capital expenditure is involved.

When the VAT Flat Rate Scheme can work well

The scheme can remain useful for a business with a favourable sector rate, relatively little recoverable input VAT and sufficient relevant goods expenditure to avoid limited cost status.

It may also provide a simpler calculation for a business whose transactions are straightforward and whose owners understand which turnover must be included.

The one per cent first-year reduction can improve the result for a newly VAT-registered business, although the benefit ends at the first anniversary of registration.

A business should assess the scheme from its own records rather than assuming that it is beneficial because another company in the same sector uses it.

When standard VAT accounting may be better

Standard VAT accounting may be more suitable where the business is regularly classified as limited cost or incurs significant VAT on purchases.

A business investing in stock, materials, subcontracted supplies, equipment or premises may lose more purchase VAT than it saves through the flat rate calculation.

The scheme can also be unsuitable where a large proportion of turnover is zero-rated or exempt but still enters the flat rate calculation.

Businesses repeatedly receiving VAT repayments under standard accounting should be particularly cautious about joining. The Flat Rate Scheme could replace those repayments with VAT liabilities.

Reviewing limited cost status every VAT period

Limited cost status is not a one-time classification completed when the business joins. The test must be performed using the figures for each VAT Return period.

The bookkeeping should record flat rate turnover, expenditure on relevant goods, the applicable percentage and the resulting calculation. HMRC requires these details to be kept with the VAT account.

Automated VAT software may assist with the calculation, but the business must still confirm that purchases have been classified correctly as goods, services, capital expenditure or excluded items.

An error can affect several returns where the same purchase rules or flat rate percentage are applied automatically. The calculation should therefore be reviewed before each submission.

Leaving the VAT Flat Rate Scheme

A business can normally leave the scheme voluntarily by notifying HMRC. The effective leaving date should be confirmed rather than assumed from the date the business decides internally to change methods.

A business must usually leave where its VAT-inclusive turnover exceeded £230,000 at the anniversary of joining or is expected to exceed that amount during the next 12 months.

It must also leave where expected income during the next 30 days alone will exceed £230,000 including VAT, or where it otherwise ceases to satisfy the eligibility conditions.

The business generally cannot rejoin until at least 12 months after leaving. The financial comparison and planned departure date should therefore be considered carefully.

HMRC’s guidance on leaving the Flat Rate Scheme explains the current compulsory exit tests.

Preparing the bookkeeping before leaving

A business leaving the scheme will need to begin recording recoverable purchase VAT under the ordinary rules from the appropriate date. Purchase invoices and VAT codes should therefore be reviewed before the first standard return is prepared.

The accounting software must be updated using the confirmed leaving date. Applying standard VAT treatment too early or continuing the flat rate calculation too long can affect more than one return.

Capital assets on which VAT was recovered separately should remain identifiable. Stock, outstanding invoices, credit notes and payments crossing the change date may also need review.

Where an earlier return requires correction, the business should preserve a clear record of the original entry, revised treatment and supporting calculation rather than making an unexplained balancing adjustment.

Making Tax Digital and the Flat Rate Scheme

Businesses using the VAT Flat Rate Scheme must still comply with Making Tax Digital for VAT unless HMRC has granted an exemption.

The business needs compatible software, digital VAT records and an electronic submission to HMRC. The scheme changes how the liability is calculated, not the requirement to maintain digital records.

Spreadsheets can remain part of the process where suitable digital links and bridging software are used. Manual copying between disconnected systems may not satisfy the digital-link rules.

Our guide to Making Tax Digital explains the wider record-keeping and software requirements applying to VAT-registered businesses.

VAT registration and the Flat Rate Scheme

A business must first be VAT registered before it can use the Flat Rate Scheme. It can apply to join during the VAT-registration process or after registration.

The Flat Rate Scheme joining threshold of £150,000 is separate from the ordinary VAT registration threshold. A business can therefore be required to register for VAT while remaining eligible to apply for the scheme.

Businesses approaching VAT registration should review pricing, customer types, purchase VAT and sector percentages before selecting a method.

Our guide to how to register for VAT explains the registration tests and records needed when taxable turnover approaches the current threshold.

The VAT Flat Rate Scheme for startups

A startup registering voluntarily may be attracted by the one per cent first-year reduction. The decision should still consider the expected level of equipment, stock, professional fees and other VAT-bearing expenditure.

A new service business may be limited cost from its first return because software, advertising and professional support are services rather than qualifying goods.

A product or trade business may incur substantial input VAT during setup. Standard VAT accounting could allow more of that VAT to be recovered than the business would retain under the flat rate calculation.

Our guide to bookkeeping for startups explains how new businesses can organise expenditure and supporting documents before VAT and tax reporting become more complicated.

Common Flat Rate Scheme mistakes

A common mistake is applying the percentage to turnover excluding VAT. The flat rate is normally applied to the VAT-inclusive amount.

Another error is using the ordinary sector percentage without completing the limited cost test for the VAT period.

Businesses may also include services or capital assets as qualifying goods, enabling them incorrectly to avoid the 16.5 per cent limited cost rate.

Some businesses reclaim VAT on ordinary purchases even though the scheme normally prevents separate input-tax recovery. Others fail to reclaim VAT on a qualifying single purchase of capital expenditure goods worth at least £2,000 including VAT.

Using the wrong sector, omitting exempt income from the calculation or overlooking the end of the first-year discount can also create underpayments or overpayments.

Bookkeeping records required for the scheme

The business should retain its ordinary sales and purchase records together with a clear flat rate calculation for each VAT period.

The calculation should show flat rate turnover, the percentage used, the VAT calculated as due and the amount spent on relevant goods for the limited cost test.

Sales, bank accounts, card processors and payment platforms should be reconciled before the return is submitted. A percentage applied to incomplete turnover will still produce an incorrect return.

Purchase invoices should remain organised even where input VAT is not reclaimed. They support the annual accounts, tax deductions, limited cost test and any future move to standard accounting.

When outsourced VAT bookkeeping helps

A business with straightforward sales and limited purchases may be able to complete its own Flat Rate Scheme returns. External support becomes more useful where turnover categories, capital purchases, limited cost tests or scheme changes need regular review.

The service scope should identify responsibility for transaction processing, VAT coding, limited cost calculations, reconciliation and submission. Advice on whether the scheme is financially optimal may require a separate tax review.

Bookkeeping Packages Ltd provides a VAT returns service where processing and submission form part of the agreed bookkeeping arrangement.

Our UK bookkeeping services can also maintain the sales, purchase and reconciliation records needed to support each return.
