About This UK Business Income Tax Calculator

Running a business in the United Kingdom comes with the responsibility of understanding and paying corporate taxes. Whether you're a limited company, small enterprise, freelancer, or entrepreneur, staying compliant with HMRC's tax rules is essential. This tool helps simplify the process by estimating how much business tax you owe based on your annual income and expenses.

How Does the Business Income Tax Work?

In the UK, businesses pay Corporation Tax on their taxable profits. The current standard rate for corporation tax is typically 25% (check HMRC for the latest updates). Taxable profit is calculated as:

• Annual Revenue – total business income earned in the year
• Allowable Expenses – legitimate costs directly related to running the business

Subtracting allowable expenses from revenue gives you your taxable profit. The Corporation Tax is then calculated based on this profit using the prevailing rate.
