Capital Allowances: Full Expensing and 50% FYA

Table of Content

Capital allowance is a relief that business can claim for the use of certain kinds of assets. The amount of relief is certain percent of the cost of such asset.

Usually, capital allowances can be claimed for the assets but not for building (unless it is a commercial property where structural and building allowance applies).

There are two types of allowances :

  • One off (first year) claim for the initial year of purchase (50% to 100% of the purchase price)
  • Subsequent yearly claims (different rates- generally 6% or 18%)

Introduction to Full Expensing and FYA

Usual rates of capital allowances (6% or 18% per year) take several years to get relief for the total amount invested in a particular asset.

However, full expensing and 50% FYA are the capital allowances that allow immediate tax relief. Whole or half of the cost can be claimed right in the year of purchase (no need to wait for several years to recover full investment).

These reliefs are available only for companies (not for sole traders and partnerships) and only when assets purchased between 1 April 2023 to 31 March 2026. As almost all companies invest in assets, they should understand these rules and must not miss the opportunity to save tax.

Full Expensing

As per full expensing, assets that would get a yearly capital allowance of 18%, can now benefit from 100% relief.

For example, a server bought for £8,000 allows you to deduct the whole £8,000 from taxable profit.

Below table shows that, claiming under main rate of 18%, even after three years, only £3,589 (out of £8,000) is recovered. However, claiming under full expensing, whole of £8,000 was claimed within the first year.

Assets Which are eligible for Full Expensing

Generally, most of the assets used for the business qualify. But below are not eligible:

  • Cars, ships, railway assets
  • Used and second-hand assets, gifted assets, assets leased to someone
  • Assets transferred from connected person
  • Land and buildings (structural and building allowances apply instead)
  • Assets under special rate pool (discussed below)
  • Assets acquired as part of arrangements which are not normal
  • Assets not used or business
  • Assets purchased during the accounting period when the qualifying activity ceases

How Super-Deduction Differs from Full Expensing

Super-deduction of 130% was available for investments before April 2023 but full expensing is available for assets bought onwards April 2023. Please visit our article “Capital Allowance Super Deduction: Can you claim after March 2023?” for further details.

50% First Year Allowance (FYA)

For investment in certain assets (on which full expensing is not available), there is another relief called 50% first-year allowance. For example, an escalator installed for £8,000 allows you to deduct £4,000 from taxable profit in the year of purchase.

In subsequent years, special rate of 6% on the balance amount can be claimed every year:

Balance Amount(£)

Year of Purchase

50% FYA on 8,000



Second Year

6% Special Rate on 4,000



Third Year

6% Special Rate on 3,760



FYA is beneficial for the assets which could not be covered by Annual Investment Allowance (which allows 100% relief).

Assets Which are eligible for 50% FYA

This relief is available in the assets coming under special rate pool. The assets under this pool are:

  • Parts of a building considered integral – known as ‘integral features’ (lifts, escalators, moving walkways, air conditioners, coolers, lighting, and power systems etc)
  • Long life assets (assets lasting for more than 25 years) purchased for £100,000 or more
  • Solar panels
  • Thermal insulation added to a commercial building or Furnished Holiday Letting

Assets Which are excluded for Claiming 50% FYA

In some conditions, there is restriction on claiming 50% FYA. Used and second-hand assets, gifted assets or assets transferred from connected person and assets leased to someone are not eligible for claiming 50% FYA even when they fall under special pool rate.

Relief You Can Claim Under Full Expensing and 50% FYA

The relief depends on the cost of asset and the rate of corporation tax. For example, if the cost is £10,000 and the company pays corporate tax at 19%:

  • full expensing will provide relief of £1,900 (i.e., 19% of £10,000)
  • 50% FYA will provide relief of £950 (i.e., 19% of £5,000)

Potential Pitfalls When Claiming Full Expensing and 50% FYA

If you plan to buy something towards the end of the company’s year-end, better not to delay.

Suppose you consider buying an asset in December 2023 (which is your company’s year-end).

Buying within December, you can claim relief immediately after December. If you buy on 1st of January 2024, then you can claim relief only after December 2024 (your company’s year-end). So, one day delay in buying delays the relief by one year.

Disposal of Assets on Which Full Expensing/FYA has been Claimed

Upon selling an asset on which full expensing was claimed, an immediate balancing charge equal to 100% of the disposal value applies. Claiming full expensing and then selling an asset for £10,000 will increase taxable profit by £10,000.

Upon selling an asset on which 50% FYA was claimed, immediate balancing charge of 50% of the disposal value arises. The remaining balance of 50% is treated in the normal way so is deducted from the special rate pool balance. Claiming 50% FYA for an asset and then selling it for £10,000 will increase their taxable profits by £5,000.
