Super-Deduction and Special Rate Allowances

The newly amended Super-Deduction and Special Rate Allowances came into force on 1 April 2021, following the release of the annual budget.

This article attempts to lay out in the simplest terms what the Super-Deduction is and where it applies in practice, as well as giving you an overview of other allowances available.

Who can claim these Super-Deduction and Special Rate Allowances?

Limited companies only.

So if you are a sole trader, or part of a partnership, then we’re very sorry, this is not for you.

What’s changed?

The so called Super-Deduction Allowance is brand new and the Special Rate Allowance now has increased benefits, providing significant tax relief to qualifying assets.

What are the benefits of the new Super-Deduction Allowance?

The Super-Deduction Allowance now provides 130% first-year tax relief on new assets which qualify as main-rate plant and machinery.

What are the benefits of the new Special Rate Allowance?

The Special Rate Allowance now provides 50% first-year tax relief on new, qualifying assets, and integral features in buildings.

Can I claim these Allowances on second-hand assets?

NO – You cannot claim these Allowances on second-hand assets.

Leased assets, cars, and machinery purchased by businesses to hire out will unfortunately be excluded too.

Why should I be aware of this?

Main-rate plant and machinery expenditure would normally only qualify for 18% main pool annual relief.

Long-life assets and integral building features would normally only qualify for 6% special pool annual relief.

These tax breaks therefore present a great opportunity – to recoup costs and expand your business.

How long are these Allowances valid for?

These new allowances will only apply to expenditure between 1 April 2021 and 31 March 2023.

You only have a couple of years to take advantage of the benefits.

Is there a cap?

There is no capital expenditure cap for the Super-Deduction and Special Rate Allowances.

Other than these new items, are there are other tax benefits I should be aware of?

Annual Investment Allowance

Aside from the newly amended items, you should be aware of a further one-year extension to the Annual Investment Allowance (AIA), which provides 100% tax relief for plant and machinery expenditure when claimed before 31 December 2021.

This covers most plant and machinery (second-hand or otherwise) and currently has a £1 million annual cap.

Am I eligible?

To be eligible for these tax breaks, you must be paying corporation tax.

How to make the most of Super-Deductions

Please remember that it is a temporary allowance – you will not be able to benefit from it forever!

The Super-Deduction Allowance is claimable until 31 March 2023.

Corporation tax is set to rise to 25% in 2023, for profits over £250,000 – this is a great time to recoup some of your future losses!

To make the most of these benefits, it is worth carefully considering the timing of any contractual arrangements and company plans.
