Faster tax relief for capital expenditure

From January 2019, businesses considering investing more than £200,000 in plant and machinery may benefit from a change to the capital allowances rules, which should allow them to obtain tax relief at a much earlier time.

Broadly, business profits, after any adjustments for tax purposes (for example depreciation of fixed assets), are reduced by capital allowances to arrive at the taxable profit.  Since capital allowancesare treated as a trading expense of a particular accounting period, they canpotentially increase a loss, or turn a profit into a loss for tax purposes. This, in turn, will have an impact on the amount of tax payable by a business – so where a business is considering expenditure on qualifying items, it may be beneficial to undertake some upfront planning.


The annual investment allowance (AIA) for capital allowances purposes is a 100% allowance for qualifying expenditure on machinery and plant.
Put simply, this means that a business buying a piece of equipment that qualifies for the AIA can deduct 100% of the cost of that asset from the business’s profit before calculating how much tax is due on that profit.

VAT-registered businesses claim the AIA on the total cost of the asset less any VAT that can be reclaimed on that asset. Non-VAT-registered businesses can claim the AIA onthe total cost of the asset.

The AIA was set at its current level of £200,000 from 1 January 2016, but it was announced in the 2018 Autumn Budget that, subject to enactment, the limit will be increased to £1,000,000 from January 2019. This measure is designed to stimulate business investment in the economy by providing an increased incentive for businesses to invest in plant or machinery.

However, the increase will only be available for a limited time. Under current proposals, the AIA limit will revert to its current level from 1st January 2021. Businesses considering making significant investments in, say, the next five years, may wish to consider bringing their purchase forward, so as to benefit from the increased AIA limit and obtain immediate tax relief on their investment.

Where a business spends more than the annual AIA limit, any additional qualifying expenditure will still attract relief under the normal capital allowances regime, but this will result in relief being spread over several years, rather than in one go.

It is worth remembering that connected companies are only entitled to one AIA between them.

Transitional rules

The legislation includes a series of transitional rules, which can be complex. It is worth seeking guidance where expenditure on qualifying Annual Investment Allowance items is being considered and the business has a chargeable period that spans either of:

a. the operative date of the increase to £1,000,000 on 1st January 2019, or

b. the operative date of the reversion to £200,000 on 1st January 2021.


Subject to enactment, the temporary increase of the Annual Investment Allowance should provide a welcome tax break.
It will help boost the cash-flow of SME businesses seeking to invest in qualifying plant and machinery, by reducing liability to income (or corporation) tax directly in proportion to capital investment for the financial year in which the expenditure was made.
