How to Legally Reduce Corporation Tax in 2025

With Corporation Tax rates currently varying from 19% to 25% based on profit levels, it is increasingly crucial for UK businesses to comprehend how to manage their tax obligations. The positive aspect? There are entirely legal methods to decrease your Corporation Tax expenses—without raising any concerns with HMRC.

At Melon Accountants, we collaborate closely with business owners to implement intelligent, ethical strategies that enhance their tax positions.

1. Claim All Allowable Business Expenses
Every legitimate expense incurred by your business to generate income is deductible from your taxable profits. This encompasses salaries, rent, software subscriptions, marketing, professional fees, and travel. Accurately recording these can significantly reduce your tax liability.

2. Use the Annual Investment Allowance (AIA)
The AIA permits businesses to deduct the full value of qualifying equipment or assets (up to a specified limit) from their profits before tax. This includes items such as machinery, computers, and office furniture.

In 2025, businesses that invest in modernisation, sustainability, or automation should definitely take advantage of this relief.

3. Maximise Pension Contributions
Employer pension contributions are tax-deductible and can lower your Corporation Tax expenses. By contributing to directors’ or staff pensions through the company, you are investing in the future while reducing your current tax burden.

4. Consider R&D Tax Credits
Research & Development (R&D) Tax Credits are not exclusively for technology companies. If you have developed a new product, enhanced a process, or invested in innovation, you may be eligible. SMEs can receive a substantial tax reduction or even a cash rebate.

✅ 5. Optimise Your Director’s Remuneration
The method by which you withdraw funds from your business impacts your tax. A tax-efficient blend of salary and dividends often results in lower overall tax compared to salary alone. We assist you in determining the optimal mix based on your business structure and objectives.
