What is Corporation Tax?

Corporation tax is a tax placed on the profits of a company. If you operate a limited company, whether in IT contracting or another industry, you are required to pay tax on your profits. The amount of corporation tax you owe depends on how much profit your company makes in a given period, typically the financial year.

For most businesses, the standard corporation tax rate applies. However, the UK tax system includes specific reliefs and lower rates for small businesses, which can significantly reduce the amount of tax owed. This is where our Corporation Tax Calculator comes in – it allows you to calculate your corporation tax quickly and understand how much tax your business needs to pay.

Who needs to pay Corporation Tax?

• Limited Companies (Ltd and PLC): All limited companies in the UK must pay corporation tax on their profits.
• Foreign Companies: Non-resident companies with UK operations (e.g., branches or offices) must pay tax on profits generated in the UK.
• Charities: Charities are exempt from tax on donations and charitable activities but may pay tax on income from non-charitable activities (e.g., trading or investments).
• LLPs: Limited Liability Partnerships (LLPs) are considered separate legal entities and must pay corporation tax on profits.
• Sole Traders and Partnerships: These businesses do not pay corporation tax. Instead, they pay income tax based on their profits.

When is Corporation Tax due?

• General Deadline: Corporation tax is due nine months and one day after the end of a company’s accounting period.
• Large Companies: Companies with profits over £1.5 million must pay corporation tax in quarterly instalments during the accounting period.
• Late Payment Penalties: Failure to pay on time can lead to penalties and interest charges.
• Tax Return Deadline: The tax return must be submitted within 12 months of the end of the accounting period.

How does the Corporation Tax calculator work?

Our Corporation Tax Calculator is designed to be as simple and user-friendly as possible. All you need to do is input your company's gross profit, and the tool will automatically calculate the following:

• Small Profit Tax: If your business’s profits fall under the small profits threshold, you will benefit from the lower tax rate of 19%.
• Main Profit Tax: For companies with profits exceeding £250,000, the standard 25% corporation tax applies.
• Marginal Relief Rebate: For companies with profits between £50,000 and £250,000, the calculator will show any applicable marginal relief, which reduces the tax burden as profits grow.
• Total Tax Due: This is the total amount of tax your company owes, taking into account all applicable rates and reliefs.
• Profit After Tax: This is the amount left after tax has been deducted from your gross profit. It's the actual profit your company will have to reinvest or distribute.
• Effective Tax Rate: This is the percentage of your gross profit that goes toward tax. It provides a clear overview of how much tax you are paying in relation to your business's profitability.

Corporation Tax rates in the UK for the tax year 2024/25

Corporation tax in the UK is based on the profits your company earns. For the 2024/2025 tax year, the following rates apply:

• Small Profits Rate (19%): If your company makes profits under £50,000, you will pay tax at the reduced 19% rate.
• Main Rate (25%): This applies to businesses with profits over £250,000. If your company’s profits exceed this amount, the full 25% corporation tax rate applies.
• Marginal Relief: If your company’s profits are between £50,000 and £250,000, you will pay a blend of the small profits rate and the main rate. This is where marginal relief comes into play, which helps reduce the impact of the higher tax rate as your business’s profits increase.

Understanding which rate applies to your business is crucial for estimating your tax liability. The Corporation Tax Calculator automatically applies the correct rates, saving you time and ensuring you’re paying the right amount of tax.
