Capital allowances remain one of the most valuable tools available to limited companies. They allow businesses to deduct the cost of equipment and machinery from their taxable profits. The Autumn Budget introduced new measures that strengthen the system and give companies more certainty when planning investment.
November is the first full month for businesses to digest these updates. Many companies are finalising year end plans, so this is the ideal time to understand how the new rules affect purchases of equipment, vehicles and technology. With Corporation Tax remaining unchanged, capital allowances play a central role in managing tax burdens and improving cashflow.
Capital Allowances
The Capital Allowances update focuses on three key points. These include the extension of full expensing, the confirmation of the Annual Investment Allowance and the clarification of certain first year allowances.
The Autumn Budget confirmed that full expensing will continue beyond the current tax year. This measure allows companies to deduct one hundred percent of the cost of qualifying plant and machinery in the year of purchase. The extension provides much needed stability. Businesses can now plan medium term investment without worrying that relief will be withdrawn at short notice.
The Annual Investment Allowance remains set at one million pounds. This covers the vast majority of small and medium sized companies. It allows businesses to claim the full cost of most equipment and assets in the year the cost is incurred. This simplifies the process and reduces the need for complicated calculations over several years.
There has also been clarification on which assets qualify for first year allowances. These include environmentally efficient equipment and certain low emission vehicles. The rules are now more consistent. This reduces confusion and helps companies decide whether a first year allowance or full expensing gives the better outcome.
These changes are designed to support investment. The government sees capital allowances as a way to stimulate productivity and to encourage companies to modernise their equipment. For small businesses, the combined effect is a more predictable and generous system.
How it impacts you
For limited company directors, these updates influence both tax planning and purchasing decisions. When a business invests in new equipment, the timing of that purchase can affect the Corporation Tax bill for the year. The extension of full expensing means that bringing forward planned investment may produce immediate tax relief rather than spreading deductions over several years.
Companies with upcoming year ends should review existing plans. Even modest purchases can create meaningful tax savings when deducted in full. This is especially helpful for businesses that have experienced fluctuating profits. Full expensing allows tax relief to match periods of higher earnings more closely.
Directors should also consider the nature of the assets they intend to purchase. Some assets qualify for first year allowances that exceed standard writing down rates. This means the type of equipment chosen can affect the total tax relief available. Clarity in the updated rules helps avoid mistakes and ensures that businesses do not miss out on relief they were entitled to claim.
Additionally, companies operating across multiple sites or using fleets should carefully assess vehicle and machinery plans. Low emission equipment may carry specific allowances that provide extra benefits. Understanding these options early in the purchasing process ensures the right decisions are made.
What you can do
Start by reviewing your planned asset purchases for the remainder of the year. Consider whether bringing those purchases forward or delaying them until after the new rules take effect will deliver the best tax outcome. Accurate forecasting is essential. It helps determine where full expensing or the Annual Investment Allowance can provide the most value.
Next, gather a complete list of existing assets and review their current allowances. Some items may qualify for enhanced relief, particularly if they fall under new first year allowance categories. Checking this now avoids missing opportunities when preparing year end accounts.
Speak with your accountant before committing to major purchases. The updated rules may shift the optimal timing or method of buying equipment. In some cases leasing arrangements may provide flexibility, while outright purchases may provide immediate tax relief. Each situation is unique and requires proper analysis.
For businesses planning larger investments, consider whether cashflow allows for accelerated spending. When used correctly, capital allowances can significantly reduce Corporation Tax liabilities. This can free up funds to reinvest in staff, equipment or expansion.
