Back to Tax Basics: How capital allowances reduce your tax bill


In the realm of business finances, many expenses can be deducted from your profits, offering a valuable opportunity to lower your tax liability. However, the landscape changes when it comes to substantial fixed asset investments, like machinery, equipment, or vehicles. To enhance your tax planning and reduce your overall tax burden, it's crucial to grasp the concept of capital allowances and how they relate to these substantial assets.

Delving into Capital Allowances

Fixed assets represent durable items used within your business for more than a year, encompassing a range of items, from office furniture to machinery and company vehicles. For accounting purposes, the cost of these fixed assets is allocated over their anticipated useful lifespan, resulting in an annual depreciation charge that reflects their diminishing value over time.

When it comes to tax matters, the depreciation expense is reversed (disallowed), and you have the opportunity to claim 'writing down allowances' instead. Notably, there's the Annual Investment Allowance (AIA) set at £1 million annually for the foreseeable future. This means that most asset purchases up to this limit can be entirely claimed in the year of purchase, though some exceptions apply, particularly for cars and items previously held for different purposes before being incorporated into your business.

The Significance of First Year Allowances (FYA)

Certain assets may qualify for 100% First Year Allowances (FYA). These assets include brand-new vehicles with zero CO2 emissions, newly-installed electric vehicle charging points, and plant and machinery intended for use in Freeports.

Writing Down Allowances (WDA)

For all other fixed assets, their costs are categorized into distinct pools based on the asset type, and Writing Down Allowances (WDA) are calculated using a reducing balance method. These pools consist of:

  • Special Rate Pool (6% rate): This includes cars (both new and used) with CO2 emissions exceeding 50 g/km, integral fixtures within commercial buildings, and long-life items with annual expenditures exceeding £100,000 (excluding structures and buildings).

  • Main Rate Pool (18% rate): This encompasses everything else, including cars with CO2 emissions ranging from over 0 to below 50 g/km.

  • Structures and Buildings Allowance (SBA): This particular allowance applies a flat rate of 3% over 33.33 years for non-residential buildings, excluding land.

Maximizing the Benefits of Capital Allowances

When you're contemplating the acquisition of capital equipment, it's worth noting that, in many instances, you can claim the tax benefit as a lump sum, even though the equipment will serve your business for several years. This can yield a favorable short-term impact on your tax obligations and cash flow.
