Capital Allowances and Business Asset Relief
Capital allowances are an important area of tax relief for UK businesses, allowing companies to claim tax deductions when they invest in certain types of assets used in the business. Rather than deducting the full cost of an asset as an expense in the profit and loss account, capital allowances allow businesses to offset qualifying expenditure against taxable profits over time.
Capital allowances generally apply to plant and machinery, which includes a wide range of equipment such as computers, office furniture, tools, vehicles used for business purposes, and manufacturing equipment. Certain fixtures within commercial buildings may also qualify for relief.
One of the most significant reliefs available is the Annual Investment Allowance (AIA). The AIA allows businesses to claim 100% tax relief on qualifying plant and machinery purchases up to £1 million per year. This means that if a company invests in qualifying equipment, the entire cost can usually be deducted from taxable profits in the year of purchase.
For companies investing in new plant and machinery, Full Expensing may also apply. Introduced to encourage investment, this relief allows companies to claim 100% first-year relief on qualifying new assets. In contrast, some assets that do not qualify for full expensing may be eligible for a 50% first-year allowance.
Assets that exceed the AIA limit or do not qualify for full expensing are typically placed into capital allowance pools. These pools are then written down annually using a percentage rate. For example:
Main pool assets are usually written down at 18% per year
Special rate pool assets are written down at 6% per year
Examples of assets in the special rate pool include integral features of buildings such as air conditioning systems or electrical installations.
Capital allowances can significantly reduce a company’s taxable profit, making them a valuable tax planning tool. For example, if a company spends £50,000 on qualifying equipment and claims AIA, its taxable profit may be reduced by the full £50,000.
However, if an asset is later sold, the company may need to adjust its capital allowance claims through balancing charges or balancing allowances.
Careful planning is therefore important when making large investments. Businesses should consider the timing of asset purchases and ensure that expenditure is structured in the most tax-efficient way.
Because capital allowance rules can be complex, particularly for larger capital projects or property purchases, professional advice is often recommended to ensure that all available reliefs are identified and claimed correctly.
