If you’ve purchased or are considering purchasing assets for your business, you may be eligible for tax relief under the Annual Investment Allowance (AIA). We’ll show you the annual investment allowance examples, vans, and all you need to know.

What is the Annual Investment Allowance

The AIA allows firms to claim tax benefits on certain assets. If you buy plants and machinery for your firm. You can deduct the cost of that asset from your profit for that year before calculating how much tax you owe on that profit under the AIA.

The government increased the amount that businesses can claim in plant and machinery costs through the AIA in January 2019. You can now invest up to £1 million and obtain tax relief up to that amount, compared to £200,000 previously.

The UK government announced on November 12, 2020, that the AIA $1 million temporary caps would be until January 1, 2023.

On January 1, 2021, the temporary £1 million caps were supposed to restore to £200,000. The extension is to “increase confidence as companies attempt to weather the outbreak and plan for the future,” according to the government.


In 2008, the Annual Investment Allowance (AIA) start to encourage firms to invest in plants and machinery in order to stimulate economic growth. One of the main benefits of the allowance is that it allows for faster tax relief because the entire cost may be in the year of purchase rather than being spread out over several years.

Annual Investment Allowance Examples

A company has a chargeable period from 1 July 2022 to 30 June 2023, the maximum AIA for this period would be £600,000, being:

  • the proportion of the period from 1 July 2022 to 31 December 2022, that is, 6/12 x £1,000,000) = £500,000; and
  • the proportion of the period from 1 January 2023 to 30 June 2023, that is, 6/12 x £200,000 = £100,000

As a result, the total AIA due for the period is £500,000 + £100,000 = £600,000.

However, the AIA would only cover up to £100,000 of the company’s actual costs from January 1, 2023, to June 30, 2023. This means that if a £150,000 machine is purchased in February 2023, just £50,000 will be eligible for AIA.

Tax relief in the form of writing down allowances, a type of tax depreciation, is available for amounts not covered by the Annual Investment Allowance Examples. The general pool (most plant and machinery) currently has an 18% write-down allowance. Whereas the special rate pool has a 6% allowance (integral features, long-life assets, partnership assets with private usage).

A new capital allowance, known as the Super Deduction, became effective on April 1, 2021. In most cases, this will be more advantageous than AIA; however, the Super Deduction is only available to corporations, hence, it is not available to unincorporated enterprises such as sole traders and partnerships/LLPs. Other items are from the Super Deduction. The most famous of which is secondhand equipment, which would still qualify for Annual Investment Allowance Examples Furthermore, even with the Super Deduction, the annual investment allowance examples will be for special rate pool items.

Eligibility for the AIA

Companies, as well as lone proprietors, are eligible to claim the payment. The AIA applies to partnerships as well, as long as the partners are people. Unless the firms are conducted on the same premises and/or conduct identical operations, a sole owner or member of a partnership with more than one business is normally eligible for the Annual Investment Allowance for each business. When the same person controls two or more limited, each company is only entitled to one AIA. Which it can allocate however it sees fit.

Changes to the Amount of the Annual Investment Allowance Vans

The amount of expenditure that can be made under the AIA has changed several times since its creation. In 2010, the expenditure amount was £50,000 to £100,000, up from £50,000 in 2008. It decreased to £25,000 from April to December 2012, before being increased to £250,000 in January 2013.

From April 2014 to December 2015, a temporary measure was implemented that quadrupled the previous sum to £500,000. The plan was for the level to revert to its prior low point of £25,000 after this period. However, the UK government announced in July 2015 that the AIA would be set at £200,000. Then, in January 2019, it was temporarily increased to £1,000,000 for the next two years.

Capital Expenditure That Qualifies for the AIA

Most assets purchased for business purposes can be claimed as qualifying expenses for AIA, with the primary categories listed below:

  • Office equipment including computer hardware and certain types of software, and office furniture
  • Parts of a building are referred to as integral features.
  • Certain fixtures, such as air conditioning, fitted kitchens, or bathroom fittings
  • Lorries or vans used for moving purposes
  • Machines used for business purposes
  • Agricultural machinery, including tractors
  • Machines used for providing entertainment, such as arcade game machines

Buildings, cars, land or infrastructure such as bridges or docks, and goods used purely for business entertainment are among the assets that cannot be claimed. Cars used for business activities can be deducted to some extent, but not as part of the AIA. Cars used by driving schools are an exception to this restriction. As they must have dual control and can thus be claimed under AIA.

Annual Investment Allowance Vans Restrictions

You can’t claim the AIA on vehicles; instead, you’ll need to claim capital allowances. This means you’ll get tax relief on your car purchase over a specified number of years based on the vehicle’s emissions.

If you’re self-employed, you won’t be able to claim this, along with any other business expenditures. If you’re claiming the HMRC trade income allowance.

You can utilize it to produce a tax loss that you can carry over against any future profits if you choose to claim it. So, if you’re just starting off and have invested in equipment. You might want to file a tax return so that you can get tax relief in the future (although you can claim for these costs in later years as pre-trading expenses).

Pro-Rating the Allowance

If your company has been in operation for less than a year, you’ll have to prorate the £1 million yearly investment allowance.

For instance, if you’ve just been in business for 6 months when filing your tax return, you’re only entitled to £500,000 (£1,000,000 x 6/12).

If you buy fixed assets for your personal use as well as your business. You’ll need to prorate AIA because you can only claim it on the business half.

For example, suppose you spend £1,500 on a laptop and use it 50% of the time in your business. You’ll be able to claim AIA on half of your laptop expenditures, or £750.

You will only receive one amount of AIA if you have two businesses that are run by you. Have similar activities, or operate from the same location. You will need to prorate it between your businesses if you have two businesses that are run by you. Have similar activities, or operate from the same location.

Capital Allowances v. Annual Investment Allowance

A yearly investment allowance is a form of capital allowance that applies only to equipment rather than cars. You could still claim capital allowances on the equipment you buy. But the amount you can claim against your taxes each year would be 18% of the cost. The AIA is better for taxes because it allows you to claim 100% of what you spend in the year you acquire it.

If you run a Limited Company, it may be more tax advantageous to claim the new capital allowance super deduction. Which is available from April 1, 2021, to March 31, 2023. Businesses can now claim 130 per cent capital allowances on eligible plants and machinery thanks to the super deduction.

How does the Annual Investment Allowance Vans work?

The solution is simple if your company’s fiscal year ends on December 31, 2021. However, if your company’s fiscal year ends before or after January 1, 2022, transitional rules will apply, and your AIA entitlement will be:

A) Based on the £1,000,000 allowance before January 1, 2022, divided by the number of months in the accounting period prior to January 1, 2022.

B) Based on the £200,000 allowance for the accounting period beginning after January 1, 2022, apportioned for the number of months in the accounting period beginning after January 1, 2022.

The maximum potential AIA for the accounting period subject to the transitional regulations is then by adding A + B.

For example, if your company’s fiscal year ends on March 31, 2022, your AIA entitlement would be as follows:

A) £1,000,000 multiplied by nine months equals £750,000 (1 April 2021 – 31 December 2021)

B) £200,000 divided by three months equals £50,000 (1 January to 31 March 2022).

A + B = £800,000 AIA maximum potential

How can the AIA become complicated?

In addition to the foregoing, the date on which the cost determines the real AIA claim (when you for the item). When the restriction is reduced, there is a further cap. The AIA limit is to the proportion of the AIA in that accounting period.

In the scenario above, if the company bought £400,000 worth of machinery on September 30, 2021, and then another £400,000 on February 28, 2022, it could appear that the total authorized expenditure of £800,000 would qualify for AIA at 100%.

The second piece of machinery, on the other hand, was after December 31, 2021. This means that the claim for that time period is to the AIA limit of £50,000. Which applies from January 1, 2022, to March 31, 2022.

As a result, the AIA claim totals £450,000 for the period (£400,000 for the first machine and £50,000 for the second). The remaining £350,000 in costs will be eligible for Capital Allowances at the regular rate of 18%. The maximum AIA of £800,000 may have been claimed if both pieces of machinery were purchased before December 31, 2021.

It is critical that you purchase ‘plant and machinery as soon as possible if you are considering doing so. It’s vital to maximize the benefits of the AIA’s enhanced rate of £1 million.

Can you choose not to claim AIA?

If you do not want to claim the full cost, for example, you have low profits, you can claim: writing down allowances instead. part of the cost as AIA and part as writing down allowances.
