When a business invests in equipment, machinery, or commercial vehicles, it may be eligible to claim tax relief through various capital allowance schemes.
These provisions reduce the amount of taxable profit, potentially lowering the Corporation Tax or Income Tax due.
The route you take will depend on several factors, including the nature of the asset, its cost, and the legal structure of your business.
This overview outlines three of the main types of capital allowances:
Full Expensing – Immediate relief for limited companies
Full Expensing permits incorporated businesses to deduct the total cost of qualifying new plant and machinery from their taxable profits in the same financial year the purchase is made.
This scheme is only available to companies liable to Corporation Tax and only applies to brand-new assets, not second-hand or leased items.
Full Expensing can be particularly beneficial for companies undertaking substantial capital investments who wish to maximise tax relief without delay.
Annual Investment Allowance – Broader access with asset flexibility
The AIA enables a wider range of businesses, such as sole traders and partnerships, to claim 100 per cent tax relief on qualifying expenditure, up to a £1 million annual cap.
In contrast to Full Expensing, AIA can be applied to new and used equipment, although some exclusions remain (such as leased or gift-acquired assets).
This scheme is well-suited to businesses seeking a straightforward way to offset moderate levels of investment.
Writing-Down Allowances – Gradual relief over time
When expenditure surpasses the AIA limit or the asset in question does not meet the requirements for AIA or Full Expensing, WDAs come into play.
These allowances allow businesses to claim a percentage of an asset’s value each year against profits.
There are two primary WDA rates:
Over time, this approach provides a phased route to tax relief.
Making a claim
Capital allowances must be included as part of your business’s tax return and can only be applied to items used wholly for business purposes.
If you use assets privately as well, only the business-use proportion is eligible.
Some additional schemes, such as allowances for environmentally beneficial investments, may offer further opportunities for relief depending on your activities and objectives.
For the most accurate guidance tailored to your circumstances, it is advisable to consult a qualified tax adviser or refer to the official guidance available at gov.uk/capital-allowances.
