Category: Capital allowances

Businesses investing in qualifying assets may be able to claim the Annual Investment Allowance (AIA) and deduct the full cost of eligible purchases from their profits before tax. This can help by reducing the amount of taxable profit in the period the investment is made.

The AIA can generally be claimed by sole traders, companies and partnerships where all the partners are individuals, on most plant and machinery up to the available allowance. The current AIA limit is £1 million, meaning many businesses can claim immediate relief on significant investments rather than spreading the tax relief over several years.

Qualifying purchases may include items such as machinery, equipment and certain business assets. However, the AIA cannot be claimed on business cars, assets previously owned for another reason before being used in the business or items given to the business.

The allowance is claimed in the accounting period when the asset is bought. Businesses should ensure they use the correct purchase date, which may depend on when contracts are signed or payments become due.

If a business does not want to claim the full amount of AIA, for example because it has low profits, it may choose to claim writing down allowances instead or split the claim between AIA and other capital allowances.

If you have invested in a new commercial building or carried out significant renovation work, you may have overlooked a valuable capital allowance. The Structures and Buildings Allowance (SBA) provides tax relief on qualifying capital expenditure incurred on certain new non-residential structures and buildings.

The SBA applies to qualifying costs incurred when constructing, purchasing or renovating qualifying commercial structures. This can include expenditure on design fees, site preparation, construction works, renovation, conversion and fitting-out costs.

The allowance was introduced in October 2018 at a rate of 2% per year on a straight-line basis. From April 2020, the annual allowance rate increased to 3%, with relief available over a period of 33 and one third years. This rate continues to apply for qualifying expenditure.

To qualify, the structure or building must be used for a qualifying business activity, such as a trade, profession, property business (excluding residential property), or certain other commercial activities. The structure must also meet specific conditions, including having an allowance statement to support the claim.

Claims are made through your tax return, and the relief can generally continue for the full allowance period where the qualifying conditions continue to be met. If you have constructed, purchased or renovated a commercial property since October 2018, it is worth reviewing whether you are claiming all the capital allowances available to you.

The Annual Investment Allowance (AIA) is a valuable tax relief that allows businesses to deduct the full cost of qualifying plant and machinery from their taxable profits. This means that, instead of claiming relief over several years, businesses can often obtain 100% tax relief upfront.

The AIA is currently capped at £1 million per year, and a fresh allowance is available for each accounting period (adjusted if the period is shorter or longer than 12 months).

Most plant and machinery qualifies, including items such as tools, machinery, vans, office equipment, computers and certain building fixtures. However, AIA cannot be claimed on cars, assets previously owned for non-business use or items given to the business.

AIA is available to sole traders, partnerships and companies. However, it is only available to partnerships where all partners are individuals, mixed partnerships that include companies do not qualify.

Timing is important. You can only claim AIA in the period the expenditure is incurred. This is usually the date the contract is signed if payment is due within four months, or the date payment becomes due if later. Special rules apply for hire purchase.

If you do not want to claim the full amount you can claim part of the cost and carry forward the balance using writing down allowances.

Used correctly, AIA can significantly reduce a business’s tax bill, particularly where there is substantial investment in equipment.

The Annual Investment Allowance (AIA) is a generous tax relief that allows for the total amount of qualifying expenditure on plant and machinery to be deducted from pre-tax profits. The maximum amount that can be claimed for the AIA is limited to a £1 million annual cap on qualifying purchases.

The AIA can be claimed by an individual, partnership or company carrying on a trade, profession or vocation, a UK non-residential property business or a furnished holiday let. Only partnerships or trusts with a mixture of individuals and companies in the business structure are unable to qualify for AIA.

The AIA is available for most assets purchased by a business, such as machines and tools, vans, lorries, diggers, office equipment, building fixtures and computers. The AIA does not apply to business cars, items you owned for another reason before you started using them in your business or items given to you or your business.

A claim for AIA must be made in the period the item was bought. This date is defined as the date when a contract was signed, if payment is due within 4 months of the contract being signed. If not, the actual payment date if it is due more than 4 months later.

The new 40% First Year Allowance (FYA) for qualifying main-rate plant and machinery expenditure first announced at Autumn Budget 2025 has now come into force.

Effective from 1 January 2026, the new FYA applies to qualifying main-rate plant and machinery expenditure. It was also announced at the recent Autumn Budget 2025 that the main rate writing down allowances would be reduced to 14% (from 18%) from 1 April 2026 for Corporation Tax purposes and from 6 April 2026 for Income Tax purposes.

These changes mean that:

• Businesses can claim a 40% FYA on qualifying main-rate plant and machinery.
• The allowance applies to assets acquired for leasing, which did not qualify from full expensing.
• Unincorporated businesses, including sole traders and partnerships can also benefit from the FYA. These businesses did not benefit from full expensing.
• The allowance is permanent, providing long-term certainty for investment and capital planning.

The new FYA complements the existing full expensing regime, which remains in place for incorporated businesses. Full expensing allows companies to deduct 100% of the cost of qualifying plant and machinery from taxable profits in the year of acquisition, delivering tax savings of up to 25p for every £1 invested, in line with the current Corporation Tax rate.

Understanding how the new 40% FYA interacts with existing allowances, including full expensing and annual investment allowances, will be important when considering expenditure going forward.

An extension of First-Year Allowances (FYA) for zero-emission cars and charge points was announced as part of the recent Budget measures.

This means that the 100% FYA for qualifying expenditure on zero-emission cars, and electric vehicle (EV) charge points will now be available until 31 March 2027 for Corporation Tax purposes, and until 5 April 2027 for Income Tax purposes. This one-year extension to the current reliefs means that eligible businesses can continue to deduct 100% of the cost of these assets from their taxable profits in the year the expenditure is incurred until the relief expires.

The FYA for cars was introduced from 17 April 2002 for low CO₂-emission vehicles, including electric cars, and was then restricted to zero-emission cars from April 2021. The FYA for electric vehicle charge points was introduced in November 2016. Both of these allowances are intended to support the UK’s move towards cleaner vehicles.

According to HMRC’s figures, this measure is expected to benefit around 13,000 incorporated businesses and 6,000 unincorporated businesses by continuing to offer 100% tax relief in the year the expenditure is incurred for qualifying expenditure on zero-emission cars and EV charge points.

Writing-down allowances (WDAs) are a type of capital allowance that let you deduct a percentage of an asset’s value from your taxable profits each year. In some cases, you may be able to claim more relief using other capital allowances, such as the Annual Investment Allowance or first-year allowances.

There are two rates of WDA for plant and machinery. To calculate them, you first group your expenditure into separate pools:

• the main pool – this includes expenditure on most items – the rate is 18%; and
• the special rate pool includes special rate expenditure including long-life assets, integral features, certain thermal insulation and some cars – the rate is 6%.

Assets are grouped into pools, and WDAs are applied to the balance of each pool after adding new purchases, deducting disposal and accounting for any private use.

The Small Pools Allowance provides an alternative to WDAs. If the balance in the main or special rate pool is £1,000 or less, you can claim the entire amount in one year rather than applying the WDA percentage. The Small Pools Allowance cannot be used for single-asset pools and is prorated for accounting periods shorter or longer than 12 months. You can choose between claiming WDAs or the Small Pools Allowance, where possible, but cannot claim both.

Buying a zero-emission electric car through your limited company could mean 100% tax relief in year one. Understand the capital allowances and boost your business’s tax efficiency with smart vehicle choices.

If you are considering purchasing a company car through a limited company, it’s important to understand the tax implications, especially the significant tax write-offs available for electric vehicles with zero emissions.

The tax treatment will depend on how the car is financed, but in most cases, the vehicle will be classified as a fixed asset, with tax relief available through capital allowances. Unlike other business assets, company cars do not qualify for the Annual Investment Allowance (AIA). Instead, they fall into specific capital allowance categories based on their CO₂ emissions and when they were purchased.

If you purchase a new and unused fully electric or zero-emission car, it qualifies for a 100% First Year Allowance (FYA). This means:

• You can deduct the full cost of the car from your company’s taxable profits in the year of purchase.
• The car must be brand new and registered as zero-emission to qualify.

If the car does not meet the criteria for 100% FYA, it will fall into one of the following categories:

• 18% Main Rate Allowance: Applies to cars with lower CO₂ emissions (but not zero). 18% of the car’s cost can be written off each year on a reducing balance basis.
• 6% Special Rate Allowance: Applies to cars with higher CO₂ emissions or certain second-hand vehicles. Only 6% of the cost is deductible each year.

When selling assets on which capital allowances were claimed, you may need to adjust your taxable profits with a balancing charge or allowance. Understanding these rules ensures you don’t face unexpected tax liabilities. Learn how to handle asset disposals correctly.

Typically, the value of the asset sold is considered to be the amount for which it was sold. However, if the asset was given away, no longer used, or sold for less than its market value, then the market value should be used.

If you initially claimed 100% tax relief on the asset, the business is required to add back the difference between the sale price and the original value to their taxable profits. This adjustment is known as a balancing charge. A balancing charge ensures that a business does not receive more tax relief than it was entitled to on the purchase of the asset. Essentially, the balancing charge operates in the opposite manner to a capital allowance, increasing the amount of profit on which tax is due.

If writing down allowances were used initially, you may face either a balancing charge or a balancing allowance.

There are specific rules that apply when calculating a balancing charge, particularly in the following cases:

• If you originally claimed a super-deduction or special rate first-year allowances.
• If you claimed full expensing or 50% first-year allowances.

In the year your business closes, instead of claiming capital allowances, you must enter a balancing charge or balancing allowance on your tax return.

Capital allowances enable businesses to claim tax relief on certain capital expenditures. Different rules apply to various types of capital expenditure, and the amount you can claim depends on the specific capital allowance you use. If an item is eligible for more than one type of capital allowance, you can choose which to apply.

The main capital allowances currently available are:

• Annual Investment Allowance (AIA) – The AIA is available to all businesses (companies, sole-traders and partnerships) regardless of size. The AIA allows businesses to write off 100% of the cost of qualifying Plant & Machinery (P&M), up to the allowed maximum, against taxable profits. You can claim up to £1 million on qualifying purchases.
• Full expensing and 50% First Year Allowances – The full expensing measure currently applies from 1 April 2023 until 31 March 2026 and allows companies to claim 100% capital allowances on qualifying plant and machinery investments. Under full expensing, for every pound a company invests, their taxes will be cut by up to 25p. For “special rate” expenditure, which does not qualify for full expensing, a 50% FYA can be claimed instead. 
• Writing down allowances – For P&M expenditure that exceeds the AIA or does not qualify for a FYA. You can claim these allowances if your plant and machinery does not qualify for AIA, or you have already claimed the maximum amount. This relief is based on the cost of the items in the year they are acquired. A standard 18% writing down allowance is available on qualifying assets. There is a lower rate of 6% available for certain long-life assets and integral features.

The Annual Investment Allowance (AIA) is a generous tax relief that allows for the total amount of qualifying expenditure on plant and machinery to be deducted from your profits before tax.

The AIA can be claimed by an individual, partnership or company carrying on a trade, profession or vocation, a UK non-residential property business or a furnished holiday let. Only partnerships or trusts with a mixture of individuals and companies in the business structure are unable to qualify for AIA. The AIA is currently available for qualifying expenditure of up to £1 million per year.

If you are thinking of incurring expenditure on large items of capital expenditure for your business before the end of the tax year, there is still time to invest in new equipment and reduce your tax bills for 2023-24. This could mean looking at accelerating plans, where possible, to incur expenditure before the end of the year and maximise relief.

The AIA is available for most assets purchased by a business, for example, machines and tools, vans, lorries, diggers, office equipment, building fixtures and computers. The AIA does not apply to cars.

A claim for AIA must be made in the period the item was bought. This date is defined as the date when a contract was signed – if payment is due within 4 months of the contract being signed – or the actual payment date if it’s due more than 4 months later.

The full expensing 100% first-year capital allowance for qualifying plant and machinery assets came into effect on 1 April 2023. To qualify for full expensing, expenditure must be incurred on the provision of “main rate” plant or machinery. It should be noted that full expensing is only available to companies subject to Corporation Tax. 

Plant and machinery that may qualify for full expensing includes (but is not limited to):

• machines such as computers, printers, lathes and planers;
• office equipment such as desks and chairs;
• vehicles such as vans, lorries and tractors (but not cars);
• warehousing equipment such as forklift trucks, pallet trucks, shelving and stackers;
• tools such as ladders and drills;
• construction equipment such as excavators, compactors, and bulldozers; and
• fixtures such as kitchen and bathroom fittings and fire alarm systems in non-residential property.

Full expensing currently applies from 1 April 2023 until 31 March 2026 although this may be extended. The super-deduction that was introduced during the pandemic ended on 31 March 2023. Under full expensing, for every pound a company invests, their taxes will be cut by up to 25p.

For “special rate” expenditure, which does not qualify for full expensing, a 50% first-year allowance (FYA) can be claimed. The 50% FYA was introduced alongside the withdrawn super-deduction and was due to end on 31 March 2023, but this 50% FYA has now been extended until 31 March 2026.

Businesses can also continue to use the Annual Investment Allowance (AIA) to claim a 100% tax deduction on qualifying expenditure on plant and machinery of up to £1m per year. This includes unincorporated businesses and most partnerships.

The term 'capital allowances' is used to describe the allowances available to businesses to secure tax relief for certain capital expenditure. The rules that govern the purchase of capital equipment such as computer equipment, vehicles and machinery by businesses are different to those for day to day business expenses that can be deducted from business income when calculating your taxable profits.

However, the fact that capital allowances have been given on the asset as a whole does not prevent a revenue deduction being made for a repair to that asset.

There are special rules for assets that are ‘integral features’. 

Integral features are:

• electrical systems, including lighting systems
• hot and cold water systems (but not toilet and kitchen facilities)
• space and water heating systems
• air-conditioning and air cooling systems
• lifts, escalators and moving walkways
• external solar shading

In general, where the expenditure on an integral feature represents 50% or more of the cost of replacing the integral feature, then the whole of the expenditure is to be treated as capital expenditure on the replacement of an integral feature for capital allowances purposes. 

If you are thinking about purchasing a company car through a limited company, there are many issues that need to be considered. In this short article we will point out some of the main issues, but it is important to research this area and weigh up all the available options. The tax treatment of the purchase will depend on how the purchase of the company car is financed.

The purchase of a company car will be classed as a fixed asset and tax relief will be obtained by way of capital allowances. Cars do not qualify for the annual investment allowance.

The amount of capital allowances that can be claimed will fall within one of the following 3 categories:

• 100% First Year Allowance. New and unused electric or zero emission cars emission cars benefit from 100% capital allowances. This means that 100% of the cost of the car can be deducted in the first year.
• 18% of the car’s value (main rate allowances). This effectively means that 18% of the purchase price can be deducted from your profits each year before you pay tax.
• 6% of the car’s value (special rate allowances). This effectively means that 6% of the purchase price can be deducted from your profits each year before you pay tax.

The difference between the main rate and special rate allowances depends on when the car was bought and its CO2 emissions. The government continues to encourage employers to choose more fuel-efficient vehicles by offering a tax incentive.

The new 100% first-year capital allowance for qualifying plant and machinery assets known as full expensing came into effect on 1 April 2023. This measure expected to help boost business investment and growth.

The Financial Secretary to the Treasury, said:

“We are determined to make the UK the best place in the world to do business, which is why businesses can start to benefit from the raft of tax cuts on offer to boost their growth. With full expensing, the more a company invests the less tax they’ll pay, and I encourage companies of any size to take full advantage of this world-leading reform.”

To qualify for full expensing, expenditure must be incurred on the provision of “main rate” plant or machinery. It should be noted that full expensing is only available to companies subject to Corporation Tax. 

Plant and machinery that may qualify for full expensing includes (but is not limited to):

• machines such as computers, printers, lathes and planers;
• office equipment such as desks and chairs;
• vehicles such as vans, lorries and tractors (but not cars);
• warehousing equipment such as forklift trucks, pallet trucks, shelving and stackers;
• tools such as ladders and drills;
• construction equipment such as excavators, compactors, and bulldozers; and
• some fixtures such as kitchen and bathroom fittings and fire alarm systems in non-residential property.

The new measure will initially apply from 1 April 2023 until 31 March 2026 although this may be extended. The super-deduction that was introduced during the pandemic ended on 31 March 2023. Under full expensing, for every pound a company invests, their taxes will be cut by up to 25p.

For “special rate” expenditure, which doesn’t qualify for full expensing, a 50% first-year allowance (FYA) can be claimed instead. The 50% FYA was introduced alongside the super-deduction and was also due to end on 31 March 2023. It will now be extended by three years to 31 March 2026.

Businesses can also continue to use the Annual Investment Allowance (AIA) to claim a 100% tax deduction on qualifying expenditure on plant and machinery of up to £1m per year. This includes unincorporated businesses and most partnerships.
