What are Capital Allowances?

Capital allowances are designed to write off the cost of purchasing a fixed asset over the life of the asset rather than in the financial year in which it was purchased. Capital allowances on the majority of assets are based upon a higher rate of allowance in the year of purchase, First Year Allowance with the balance of the cost being written off at a lower rate, Writing Down Allowance. The full cost of any asset may be claimed as an expense in the year it is sold or scrapped less the total of accumulated capital allowances that have been claimed against taxable profits. Any sales proceeds over and above the written down value after Capital Allowances is added back to net profits and becomes taxable. Cars are subject to writing down allowances but not First Year Allowances unless they are classed as commercial vehicles. DIY Accounting has small business software templates that automate the calculation of capital tax allowances.
