The corporation tax rate is calculated automatically based on your company's taxable profits - you don't need to input it manually.
How it works: - 19% applies to profits up to £50,000 - 25% applies to profits over £250,000 - Marginal relief applies between £50,000 and £250,000 (effective rate between 19-25%)
If you're seeing 25% but expect 19%, please check your taxable profit amount - is it under £50,000?
If your profit is genuinely under £50,000 and it's still showing 25%, please let us know so we can investigate.
