Maximising Tax Savings with the New First Year Allowances Rule in the UK

The UK tax landscape has undergone a significant change with the introduction of the new First Year Allowances (FYA) rule, which has replaced the Super Deduction Capital Allowances. Businesses need to understand the implications of this new rule and how it can help them maximise their tax savings. In this blog post, we will explore the FYA rule and the tax-saving opportunities it presents, including potential savings of up to 26% due to the marginal rate.

Understanding the First Year Allowances Rule

The new First Year Allowances rule is designed to encourage businesses to invest in qualifying assets by providing 100% tax relief on eligible capital expenditures during the first year. This relief is available for investments in plant and machinery, fixtures and fittings, and commercial vehicles, among others. The FYA rule aims to boost business investment, promote economic growth, and facilitate the acquisition of more energy-efficient and environmentally friendly equipment.

Benefits of the First Year Allowances Rule

  1. Enhanced Tax Relief: FYA provides businesses with enhanced tax relief, allowing them to claim 100% of the cost of qualifying assets in the first year of ownership, as opposed to the previous Annual Investment Allowance (AIA) which provided relief at a lower rate.
  2. Faster Tax Savings: By allowing companies to claim 100% relief in the first year, the FYA rule enables businesses to accelerate their tax savings, leading to improved cash flow and the opportunity to reinvest the savings in other areas of the business.
  3. Environmental Benefits: The FYA rule encourages businesses to invest in energy-efficient and environmentally friendly assets, promoting the adoption of green technology and helping to reduce carbon emissions.
  4. Preserving the Annual Investment Allowance: Importantly, claiming FYA does not impact your Annual Investment Allowance (AIA) limit. This means that you can take advantage of the 100% tax relief provided by the FYA rule without using up your AIA, allowing for further tax savings on other qualifying capital expenditures.

Maximising Tax Savings: Up to 26% Due to Marginal Rate

The First Year Allowances rule, when combined with the marginal rate of corporation tax, can lead to tax savings of up to 26% for businesses. To achieve this, businesses need to carefully plan their investments and consider the impact of the FYA rule on their tax liability.

Here’s how it works:

  1. Claiming FYA: Ensure that your business invests in eligible assets and claims the First Year Allowance on these investments. This will allow you to claim 100% relief on the cost of the assets during the first year of ownership.
  2. Utilising Marginal Rate Relief: By claiming the FYA, your business can reduce its taxable profits, potentially bringing it into a lower corporation tax band. This means that you could benefit from a lower marginal rate of tax, leading to additional tax savings.
  3. Timing Your Investments: To maximise your tax savings, consider the timing of your investments in qualifying assets. By planning your investments strategically, you can ensure that you benefit from the FYA rule and the lower marginal rate of corporation tax in the most effective way.


The new First Year Allowances rule presents a valuable opportunity for businesses to maximise their tax savings and invest in environmentally friendly assets. By understanding the FYA rule, planning investments strategically, and utilising the marginal rate of corporation tax, businesses can potentially achieve tax savings of up to 26%. It is essential to consult with a tax professional to ensure that your business is taking full advantage of the tax-saving opportunities presented by the FYA rule and preserving your Annual Investment Allowance limit.
