Understanding Corporation Tax in the UK 2024/25

Running a successful business means staying on top of your tax obligations. With significant changes announced in the 2024 Autumn Budget, understanding corporation tax is more important than ever for UK businesses. Let’s break down what you need to know and how these changes might affect your company.

The Basics: What is Corporation Tax?

Corporation tax is the tax your company pays on its profits. Think of it as the business equivalent of income tax that individuals pay. It applies to:

• Profits from trading
• Investment income
• Gains from selling assets

Understanding the New Tax Rates

The 2024 Autumn Budget confirmed a tiered system that works like this:

For Smaller Businesses (Profits up to £50,000)

You’ll pay the small profits rate of 19%. This lower rate helps smaller businesses manage their tax burden while growing their operations.

For Medium-Sized Businesses (Profits between £50,000-£250,000)

You’ll benefit from marginal relief – a gradual increase in the tax rate as your profits rise. This prevents sudden jumps in your tax bill as your business grows.

For Larger Businesses (Profits over £250,000)

You’ll pay the main rate of 25%. While this might seem high, it’s still the lowest rate among G7 countries, helping keep the UK competitive internationally.

What’s New in 2024?

The Autumn Budget brought several important changes that could affect your business planning:

Long-Term Certainty

The government has committed to capping the main rate at 25% throughout this Parliament. This stability helps you plan ahead with confidence. For tips on long-term financial planning, check out our bookkeeping essentials guide.
