1. What are Capital Allowances?

A Tax Relief for Spend on Business Assets

Capital allowances provide tax relief for capital expenditure incurred on business assets. This means you can deduct part or all of the value of certain assets from your taxable profits. Whether you’re a sole trader, partnership, or limited company, knowing which assets qualify and how to claim them can make a big difference in your final tax bill.

2. Identify Qualifying Expenditures

From machinery to fixtures

To make the most of capital allowances, start by identifying expenditures that qualify. These commonly include:

Office, factory, CCTV cameras

3. Make the Most of the Annual Investment Allowance (AIA)

Deduct the full value

The AIA allows businesses to deduct the full value of qualifying plant and machinery costs from their profits, up to a set annual limit. For most businesses, this is the quickest and most generous way to claim capital allowances. For the tax year 2024/25, the AIA remains at a high threshold of £1 million, making it a powerful tool for those who act before the self-assessment deadline.

Tip: If you made qualifying purchases late in the 2023/24 tax year or early in the 2024/25 tax year, be sure to check how these expenditures align with your business’s financial year-end to ensure you maximise claims effectively.

4. Don’t Forget Writing Down Allowances (WDAs)

Deduct a percentage of the asset’s value

If you have investments that don’t qualify for the AIA or first-year allowances or you’re out of the window of opportunity, WDAs are a reliable option. WDAs enable you to deduct a percentage of the asset’s value each year. The rates typically range from 6% to 18% depending on the type of asset. It’s a slower route, but an essential tool for assets that exceed the AIA threshold.

5. Check Past Expenditures for Missed Claims

Potentially reveal unclaimed allowances

It’s common for business owners to overlook capital allowances on older investments. Reviewing expenditures from previous years can reveal unclaimed allowances that can be included in your current tax return. This is known as a capital allowance pool and can be claimed at the applicable WDA rates.

6. Seek Professional Guidance

Navigating capital allowance rules can be complex, especially for larger or unique investments. Consulting with a tax advisor or claims analyst can help ensure you’re not missing out on valuable tax relief.
