The super-deduction allowance is the most attractive tax incentive for business investment ever offered by a British government. Your company can claim back up to 25p for every pound you invest in ‘qualifying’ machinery and equipment for two years from 1 April 2021.

From Chancellor Rishi Sunak’s perspective, it’s a “direct way to help businesses invest” and “drive growth in the economy”.

Your business could cut taxes by benefiting from significant capital allowance measures on qualifying plant and machinery.

  • The super-deduction – 130% first-year relief
  • The 50% first-year allowance
  • Annual Investment Allowance (AIA) providing 100% relief
From 1 April 2021 to 31 March 2023, companies can claim 130% capital allowances on plant and machinery investments that would usually qualify for 18% tax relief. For example, a company investing £100,000 could claim a deduction of £130,000 against taxable profits, saving up to 19% of that – or £24,700 on its corporation tax bill
This is a special rate first year allowance (FYA) for plant and machinery which covers new plant and machinery that would usually qualify for the special rate of 6% tax relief, including integral features in a building and long life assets.
The annual investment allowance (AIA) lets a business deduct 100% of the cost of qualifying plant and machinery assets from their taxable profit, in the tax year of purchase. It means a business can save £1 in taxable profits for every £1 spent, up to a maximum of £1m per tax year.

What is the super-deduction?

For two years from 1 April 2021, any investments your business makes in main rate (main pool) plant and machinery will qualify for a 130% capital allowance deduction. 

You will also benefit from a 50% first-year allowance for qualifying special rate (including long life) assets – the Chancellor has called this the ‘SR allowance’.

Both the 130% super-deduction and 50% first-year SR allowance could reduce your corporation tax bills until 2023 because they give qualifying equipment a much higher tax deduction in the tax year of purchase than would otherwise normally occur, i.e. the ‘first year allowance’ (FYA).

We explain more about what constitutes ‘qualifying’ spending below.

Why has the government introduced the super-deduction?

In a nutshell, the super-deduction tax break is intended to spur business investment, boost the UK’s post-pandemic economic recovery, and improve the country’s productivity levels over the next two years. 

This should in turn lead to more corporate profits for the government to tax in 2023.

Since the pandemic, previously low levels of business investment have fallen even further, “with a reduction of 11.6% between Q3 2019 and Q3 2020”, according to the Treasury’s super-deduction fact sheet. “Making capital allowances more generous works to stimulate business investment,” the Treasury explains. “As a result, these measures can promote economic growth and counter business cycles … The super-deduction will give companies a strong incentive to make additional investments, and to bring planned investments forward.”

How does the super-deduction work? 

The new tax relief is being introduced for two years for expenditure from 1 April 2021 to 31 March 2023 – sadly it’s only a temporary measure.

How does it work? Let’s look at the 130% first-year relief on qualifying main rate plant and machinery investments made during this period. Here’s an example:

Let’s say your business spends £100,000 on main rate equipment and you’re eligible to claim the super-deduction tax break on this expenditure. 

When you calculate your taxable profits your corporate tax deduction will be £130,000 (i.e. 130% of your initial investment). Deducting £130,000 from your taxable profits will save your business up to 19% of that – 19% of £130,000 is £24,700. And that’s how much corporation tax you save if you qualify for super-deduction.

Bear in mind that this is a 130% deduction for investments that would normally qualify for 18% plant and machinery writing down allowances (or capital allowances). And the first-year allowance of 50% on special rate pool expenditure would normally only attract 6% writing down allowances.

From an accounting perspective, our advice for businesses looking to maximise your tax savings is to plan well ahead. 

What is an example of the ‘SR allowance’ for special rate assets?

We’ve given an example above of how the super-deduction can apply to main rate expenditure. The SR allowance works in a similar way to the super-deduction.

Here’s how you might calculate your tax savings on special rate pool expenditure:

Let’s say you spend £1m on assets that don’t qualify for the main pool – perhaps integral features of a building, or assets that have an expected life of more than 25 years.

In the first year the SR allowance gives you a tax deduction of £500,000 to offset against your corporation tax profits. This will give you a tax deduction of 19% of this sum, i.e. £95,000, off your tax bill. You will obtain tax deductions in the subsequent years in the usual way for the remaining £500,000 of capital allowances at 6% per annum.

Should I use the annual investment allowance instead of the SR allowance?

Yes, probably.

The Chancellor has confirmed the extension to the £1m annual investment allowance (AIA) until 31 December 2021. So the AIA is available alongside the SR allowance and super-deduction.

The AIA gives 100% tax relief for costs of qualifying plant and machinery in the year of purchase. In other words you can deduct the full value of an item that qualifies for AIA from your profits before tax, for financial expenditure on up to £1m of qualifying plant and machinery.  

Now, since the SR allowance is only 50%, it will probably make sense for you to allocate the AIA against your first £1m of special rate assets, because you can claim a 100% deduction rather than 50%.

How does AIA work? Let’s say you spend £1m on integral features of a building. The AIA gives you a tax deduction of £1m against your corporation tax profits. At the prevailing corporation tax rate of 19% this gives you £190,000 off your corporation tax bill.

Best of all, the AIA does not give rise to a balancing charge when you dispose of assets (see ‘What are the pitfalls…’ below).

So, the only case where you’d be better off claiming the SR allowance rather than the AIA would be if you spend more than £1m on special rate pool additions (not including cars!)

What happens if I sell an asset on which my company has claimed either the super-deduction or SR allowance?

Be aware that the Chancellor’s generosity might have a sting or two in the tail.

Despite obtaining a 130% or 50% up-front deduction you will need to track your assets for capital allowances purposes, so that you make sure they are given the right tax treatment at the time of disposal.

On disposal of main pool items you will automatically suffer a balancing charge (i.e. you’ll be taxed on the sales proceeds) rather than taking the proceeds to the relevant capital allowances pool as you would without these new allowances. On disposal of special rate pool items you will suffer a balancing charge of 50% of the proceeds – the other 50% will be deducted from the special rate pool.

The timing matters. If the date of disposal is after 1 April 2023 then the 25% corporation tax rate applies to the balancing charge. For main rate pool items you will have obtained tax relief of 24.7% (130% of 19%). For special rate pool items your relief was only at 19%, but as you would normally expect to keep them for some years this is probably not going to prevent you from incurring the expenditure.

Where the date of disposal is prior to 1 April 2023 and you claimed a super-deduction, the disposal value you bring into account is 1.3 times the actual disposal value.

What about tax losses?

Like all other capital allowances, any deductions that you cannot use in the current year can be carried forward as tax losses to future years. For example, if you spend £1m on computer equipment you obtain a super-deduction of £1.3m. If your profits before capital allowances are £100,000 you therefore have excess losses of £1.2m to carry forward to use against profits in subsequent years. Again, you will have to forecast in order to determine whether either the capital allowances pool or your tax losses would be more beneficial in your business. Your accountant will be able to help you with this.

Is my business eligible for the super-deduction?

Your business is eligible if you spend money on any of the assets listed below between April 1 2021 and March 31 2023.

What does the government mean by ‘qualifying’ plant and machinery?

In other words, for what equipment can I claim the super-deduction or the SR allowance?

Not all business investments will qualify for the new allowances, but the qualifying groups are quite wide:

  • ‘Super-deduction’ includes all new plant and machinery that would ordinarily qualify for the 18% main pool rate of capital allowances (writing down allowances). Examples include:
    • computer equipment and servers
    • tractors, lorries, vans
    • ladders, drills, cranes
    • office chairs and desks
    • electric vehicle charge points
    • refrigeration units
    • compressors.
  • ‘SR allowance’ covers new plant and machinery that qualify for the 6% special rate pool, including integral features in a building and assets with a life of over twenty-five years. Examples include:
    • solar panels
    • foundry equipment
    • water pipes within a building
    • an electrical system within a building.

Bear in mind that that certain expenditure is excluded, for example, the acquisition of company cars, as well as the purchase of second-hand plant and machinery. 

Can I claim super-deduction if I use asset finance?

In the draft super-deduction legislation (published on 3 March 2021) plant and machinery investment incurred under “a hire purchase or similar contract” has to meet “additional conditions” to qualify for the super-deduction.

Some people have inferred that the 130% tax break therefore excludes hire purchase (or asset finance arrangements more broadly). In fact, in a scenario where your company makes payments in order to acquire an asset, and where there is an expectation that legal ownership of the asset will at some point pass to you (i.e. the lessee, as it typically the case with hire-purchase agreements), the super-deduction should be available to you. But you need to be aware of the anti-avoidance provisions that apply to, for example, contrived arrangements, agreements with connected parties, and second-hand assets. And there is a clawback of the tax saving if your business disposes of the asset prior to 1 April 2023.

Can I make a super-deduction claim if I’m in a partnership?

The super-deduction and the SR allowance don’t apply to partnerships or individuals. You need to have a company to get these valuable reliefs.

I’ve already made an order but it hasn’t arrived yet – will this qualify?

No, you need to have spent the money during the time period specified, i.e. between 1 April 2021 and 31 March 2023.
