Corporation Tax Rates in the UK
Corporation Tax rates depend on the level of company profits:

- Main rate: 25% (for higher profits above threshold)
- Marginal relief may apply for companies between thresholds
These rates can change, so using an updated calculator ensures accurate estimates.
Corporation Tax Formula (How It Is Calculated)
The basic formula for corporation tax is:
Corporation Tax = Taxable Profit × Tax Rate
Example 1 (Small Company):
- Profit: £50,000
- Rate: 19%
Tax = £50,000 × 19% = £9,500
Example 2 (Higher Rate Company):
- Profit: £200,000
- Rate: 25%
Tax = £200,000 × 25% = £50,000
