How to Reduce Corporation Tax in the UK: 11 Strategies for 2025

Businesses in the UK may find it difficult to navigate the complicated world of corporate taxation, particularly in light of the constantly changing tax environment in 2025. One of the biggest costs for businesses of all sizes is corporation tax, which has a direct effect on your bottom line. The good news? If you’re wondering how to reduce corporation tax, it can be done in legal and calculated ways while staying fully compliant with HMRC requirements.

Eleven useful tactics that can assist UK companies in maximising profits, improving their tax position, and reinvesting savings into expansion will be covered in this guide. Knowing these strategies could have a significant impact on your financial situation, regardless of whether you run a startup, SME, or established business.

#1 Pay Yourself Tax-Efficiently:

Making the most of your self-payments as a business owner is one of the best strategies to lower corporation tax. Think about combining your pay and dividends instead of treating all of your income as a salary, which is subject to both income tax and National Insurance contributions. Compared to salaries, dividends are subject to lower tax rates and are paid from the company’s profits after corporation tax.

Finding the ideal balance between dividends and salary might help you lessen your personal tax obligation and possibly lower the corporation tax for your business as a whole. To avoid fines or unforeseen tax payments, it’s critical to thoroughly plan and make sure your strategy complies with HMRC regulations.

#2 Claim Allowable Business Expenses:

Corporation tax should only be paid on profits after allowable business expenses have been subtracted. Certain business equipment, professional fees, utilities, travel expenses, and office supplies can all lower taxable profits. Maintain thorough records and receipts to make sure you are claiming all of your entitlements under HMRC regulations.

#3 Use the Annual Investment Allowance (AIA):

Businesses can deduct the entire cost of qualified assets, including machinery, equipment, and some technology, from taxable income in the year of purchase due to the Annual Investment Allowance. AIA is a potent instrument for reinvesting in your company because it instantly lowers your corporate tax bill.

#4 Claim Marginal Relief for Mid-Sized Profits:

If your profits are between the main corporation tax rate threshold and the small profits rate, you can be eligible for marginal relief. As a result, mid-sized enterprises’ tax burden is lessened as the effective corporation tax rate is gradually lowered. To get the most out of your profits, be sure they are computed correctly.

In the UK, the tax rate depends on how much you earn. Businesses with lower profits pay a lower small profits rate. Whereas, more profitable companies pay the main rate. If your profits fall between these two levels, you may qualify for marginal relief, which gradually reduces the amount of tax you pay and prevents you from moving straight to the higher rate.

#5 Make Pension Contributions from the Company:

Making contributions to pensions through your business is an easy approach to lowering your corporation tax liability. Your taxable gains are reduced because these payments are considered deductible business expenses. Company pension contributions, as compared to salary or profits, are a wise approach to save for the future and lower your tax liability because they are not subject to national insurance.

Let’s take an example to understand better:

If your company makes £50,000 profit and pays £5,000 into your pension, the profit for tax purposes drops to £45,000. This means you pay corporation tax on £45,000 instead of £50,000. This way it saves tax while boosting your pension.

#6 Utilise R&D Tax Credits:

Research and development (R&D) tax credits can be available to your company if you invest in creating new goods, methods, or technology, or in enhancing current ones. This means that you can invest in innovation and receive a reduction in your corporation tax payment or, in certain situations, cash back from HMRC.

#7 Apply for Patent Box Tax Relief:

Businesses in the UK can pay less corporation tax on profits from patented ideas or specific forms of intellectual property, due to the Patent Box scheme. Qualifying profits are taxed at a much lower rate of 10% rather than the full tax rate.

Your company’s tax liability may be greatly reduced if it creates novel items or has patents. To reap the benefits, you must demonstrate that your business contributed to the patent’s development and actively owns or solely licenses it.

#8 Use Loss Relief (Carry Back or Forward):

It is not necessary to waste money if your business has a trading loss. HMRC enables you to lower corporate tax by deducting losses from past, present, or future income.

• Carry back: Subtract losses from gains from the prior year and get a refund.
• Carry forward: Reduce taxes due to future profits by offsetting losses incurred in the past.

Effective use of loss relief smooths cash flow and guarantees that during challenging trade times, you are not paying more taxes than necessary.

Here’s an example for easy understanding:

Your company makes a £20,000 loss in 2024.

• Carryback: You may deduct this loss from 2023 earnings. You might get your 2023 corporation tax refund if you made a profit of £20,000.

• Carry forward: If you expect a £30,000 profit in 2025, you can use the £20,000 loss from 2024 to lower the taxable profit to £10,000. This will result in a significantly lower tax liability in 2025.

In this manner, your tax cost is reduced rather than wasted.

#9 Take Advantage of Creative Industry Tax Reliefs:

If your company operates in the film, television, video game, theater, or other creative sectors, you can be eligible for additional tax benefits. This enables businesses within the creative sector to cut costs by deducting a portion of their expenses through reduced tax or HMRC payments, thereby funding more talent and initiatives in the UK.

Example: A video game studio can claim back a portion of the money it spends developing a new game, reducing its overall tax bill.

#10 Structure Your Company Tax-Efficiently:

The form of your business might have a significant impact on your corporation tax liability. You may boost cash flow and lawfully lower your tax burden by carefully selecting the best structure.

• Group Structures: It can be useful to establish a group structure if you manage multiple businesses. It enables your businesses to pool resources and, most significantly, to share tax advantages. For instance, you can utilise a company’s losses to lower the taxable profits of another company in the group. This lowers the group’s overall corporation tax.

• Separate Intellectual Property (IP): Think about keeping the intellectual property (IP) in a different firm if your company creates creative assets like games, movies, music, graphics, or scripts. This can:
  
  • Defend priceless rights against commercial hazards.
    
  • Permit you to take advantage of the Patent Box program, which offers a lower tax rate of 10% on all eligible IP profits.
    
  • Make foreign expansion and licensing easier and more tax-efficient.

• Plan Dividends vs. Salaries: As a company director, you can decide how to pay yourself, through a salary, dividends, or a mix of both.
  
  • Salary: It lowers your corporation tax because it is considered a business expense, but you still have to pay PAYE and national insurance on it.
    
  • Dividends: They are often subject to lower personal tax rates than salaries, although they are not deductible.
    
  • Balanced Approach: To keep taxes lower overall, many directors take a minimal salary in order to be eligible for state pensions and benefits, and the remainder as dividends.

• Consider International Expansion: If you work with clients or projects from other countries, you may be able to reduce your overall taxes by establishing a portion of your firm abroad or by using subsidiaries in low-tax nations. However, it’s crucial to seek professional assistance in order to adhere to UK tax laws and prevent paying taxes twice.

#11 Claim Tax Relief on Goodwill and Intangibles:

Purchasing another company usually results in the acquisition of more than just tangible assets. Intangible assets include things like customer lists, goodwill, brand identities, and intellectual property. You may be able to seek relief on some of these expenses under the UK tax system, which might lower your Corporation Tax liability.

What Counts as Intangibles?

• Goodwill – the value of a company’s reputation, loyal customers, and brand recognition.
• Customer Relationships – established client contracts and contact databases.
• Trademarks and Brand Names – protected names, logos, or designs.
• Intellectual Property (IP) – patents, copyrights, and design rights.
• Publishing Rights, Film Rights, Game Assets – often key for creative industry businesses.

Example: If your business purchases another company and pays £100,000 for goodwill, you might be eligible to deduct a portion of that sum from your earnings. This results in a decreased tax obligation since it reduces the profit amount needed to compute corporate tax.

Another example is: If your company spends £50,000 to buy a patent, you may be able to write off this cost against your profits. That means your taxable profit is reduced, lowering the corporation tax you need to pay.

Bonus Tip – Register for VAT if Eligible

Value Added Tax, or VAT, is sometimes viewed as an additional expense, but if properly handled, it may actually save your company money and enhance cash flow.

When Do You Need to Register?

• VAT registration is required if your taxable turnover in any 12 months is above £90,000 (2024/25 level).
• You can voluntarily register if your turnover is less than this amount.

Conclusion

It can be quite difficult to manage corporation tax, particularly due to frequent UK tax structure changes. The good news is that there are many clever and lawful ways to lower your tax liability while maintaining complete compliance with HMRC regulations. Making use of reliefs like R&D credits, the Patent Box, or loss relief, as well as paying yourself tax-efficiently and claiming all permitted costs, can all have a significant impact on your bottom line.

It’s always worthwhile to seek professional tax advice if you’re not sure which techniques are best for your business. Your company may save thousands of dollars in 2025 and beyond with a little preparation now.
