Key Changes to Corporation Tax in the UK Budget 2025

The government has announced modifications to the corporation tax rate and introduced new rules affecting taxable profits. These changes aim to balance revenue generation with encouraging business growth.

• Corporation Tax Rate Adjustment

The main rate of corporation tax will increase from 25% to 26% starting April 2025. This marks a slight rise compared to previous years and will impact the net profits companies retain.

• Thresholds for Small Profits

Companies with profits below £50,000 will continue to pay a reduced rate of 19%. This threshold remains unchanged, providing relief for smaller businesses.

• Marginal Relief Changes

The marginal relief band, which applies to companies with profits between £50,000 and £250,000, will be adjusted to reflect the new main rate. This means businesses in this range will face a gradual increase in their effective tax rate.

How These Changes Affect Different Business Sizes

The impact of the corporation tax changes varies depending on the size and profitability of a company.

Small Businesses

Small businesses earning less than £50,000 in profits will see little to no change in their corporation tax liability. The government’s decision to keep the small profits rate at 19% helps protect these companies from increased tax burdens.

Medium-Sized Businesses

Companies with profits between £50,000 and £250,000 will experience a gradual increase in tax rates due to the adjusted marginal relief. For example, a business with £150,000 in profits may see its effective tax rate rise from approximately 21% to around 22.5%.

Large Businesses

Businesses with profits exceeding £250,000 will face the full 26% corporation tax rate. This increase will reduce after-tax profits and may influence decisions on reinvestment, dividends, and expansion.

Practical Examples of Corporation Tax Impact

To illustrate the effect of the new rates, consider the following examples:

• A company with £40,000 in profits will continue to pay 19%, resulting in a tax bill of £7,600.

• A company with £150,000 in profits will pay a marginal relief rate, leading to an estimated tax bill of £33,750, up from £31,500 previously.

• A company with £500,000 in profits will pay 26%, resulting in a tax bill of £130,000, compared to £125,000 at the 25% rate.

  
  

These examples highlight how the tax increase affects profitability and cash flow.

Implications for Business Planning and Investment

The rise in corporation tax rate means companies need to reassess their financial strategies. Here are some areas to consider:

• Investment Decisions

Higher taxes reduce available capital for investment. Businesses may delay or scale back projects unless they expect strong returns.

• Dividend Policies

Companies might adjust dividend payouts to shareholders to balance tax liabilities and shareholder expectations.

• Tax Planning

Effective tax planning becomes more critical. Businesses should explore reliefs, allowances, and timing of income recognition to manage tax bills.

Government’s Rationale Behind the Changes

The government aims to increase tax revenues to fund public services and reduce the budget deficit. At the same time, it seeks to maintain a competitive environment for businesses by protecting small companies and providing transitional relief for medium-sized firms.

What Businesses Should Do Next

• Review Financial Forecasts

Update profit projections to account for the new tax rates.

• Consult Tax Professionals

Seek advice on how to optimize tax positions under the new rules.

• Explore Reliefs and Allowances

Identify any available tax reliefs that can reduce liabilities.

• Plan for Cash Flow Changes

Adjust budgets to accommodate potentially higher tax payments.
