Tax & Revenue Rates (2026/27)
The Corporation Tax framework continues to operate with a tiered system based on company profitability:
- Small Profits Rate (19%): Applies to companies with taxable profits under £50,000.
- Main Rate (25%): Applies to companies with taxable profits over £250,000.
- Marginal Relief: Companies with profits between £50,000 and £250,000 pay the main rate of 25% reduced by marginal relief, creating an effective sliding scale.
- Associated Companies: Thresholds are divided by the number of associated companies under common control.
