Corporation tax is one of the biggest costs for UK limited companies, but the good news is there are completely legal ways to reduce what you pay.

With tax rules evolving in 2026, planning ahead is more important than ever. Here are 10 practical and compliant strategies to help lower your corporation tax bill.

1. Claim All Allowable Expenses
Make sure you are claiming every business expense that is wholly and exclusively for your business. This includes software, travel, office costs, insurance, and professional fees.

2. Use the Annual Investment Allowance (AIA)
You can claim 100% tax relief on qualifying equipment and machinery purchases. This reduces your taxable profit significantly in the year of purchase.

3. Take Advantage of First year allowance(FYA)
If your company invests in plant and machinery, full expensing allows you to deduct the full cost against profits immediately, rather than spreading it over years.

4. Optimise Director Salary and Dividends
A well-balanced salary and dividend strategy can reduce both corporation tax and personal tax. With dividend rates changing from April 2026, this needs careful planning.

5. Contribute to a Pension
Employer pension contributions are a tax-efficient way to extract profits. They are deductible for corporation tax and do not attract National Insurance.

6. Claim R&D Tax Relief (if applicable)
If your business is involved in innovation, product development, or technical improvements, you may qualify for Research and Development tax relief.

7. Utilise Losses Properly
If your company has made losses, these can often be carried forward or back to offset against profits, reducing your tax bill.

8. Consider Timing of Income and Expenses
Delaying income or accelerating expenses (where appropriate and compliant) can help reduce profits in a higher tax year.

9. Use Trivial Benefits and Allowances
Providing small, tax-free benefits (like £50 gifts) can be a tax-efficient way to extract value without increasing taxable profit significantly.

10. Review Your Structure
In some cases, restructuring your business or using group relief (if you have multiple companies) can reduce overall tax liability.

Final Thoughts

Reducing your corporation tax bill is not about avoiding tax, it is about planning properly and using the reliefs available to you.

With upcoming changes in 2026, including increased scrutiny and reporting requirements, getting advice early can make a big difference.

If you want to make sure you are not overpaying tax, now is the time to act.
