As a result of the measures announced in the 2021 Budget, businesses have benefited from four significant capital allowance measures – Super-Deduction is one of them!

With a 11.6% reduction in business investment between Q3 ’19 and Q3 ’20 it comes as no surprise that the government introduced the super-deduction to give companies a strong incentive to bring planned investments forward and even make additional investments.

According to gov.uk “The government has offered unprecedented support for businesses during Covid. Even so, pandemic-related economic shocks and the accompanying uncertainty have chilled business investment. This super-deduction will encourage firms to invest in productivity-enhancing plant and machinery assets that will help them grow, and to make those investments now”

Examples of the super-deduction in practice

Example one
• A company incurring £1m of qualifying expenditure decides to claim the super-deduction
• Spending £1m on qualifying investments will mean the company can deduct £1.3m (130% of the initial investment) in computing its taxable profits
• Deducting £1.3m from taxable profits will save the company up to 19% of that – or £247,000 – on its corporation tax bill.

Example two

Previous System

With Super-Deduction

· A company spends £10m on qualifying assets

· Deducts £1m using the AIA in year 1, leaving £9m

· Deducts £1.62m using WDAs at 18%


· Deductions total £2.62m – and a tax saving of 19% x £2.62m = £497,800


· The same company spends £10m on qualifying assets

· Deducts £13m using the super-deduction in year 1



· Receives a tax saving of 19% x £13m = £2.47m
