Historical Context
The concept of progressive taxation has been fundamental in tax systems worldwide, aimed at ensuring that individuals with higher incomes contribute more significantly to public finances. The additional rate, often referred to as the higher rate of income tax, typically applies to the highest income brackets. This tiered approach helps in achieving economic equity and funds public services.
Types/Categories

- Capital Gains Tax: Higher rates may apply to significant gains from investments.
Key Events

- Revisions: Various countries have adjusted their thresholds and rates over time to reflect economic conditions.
Detailed Explanations
The additional rate typically applies to income that exceeds a pre-defined threshold. For example, in the UK, the additional rate is currently 45% for annual incomes over £150,000. This helps to ensure a progressive tax system, where tax rates increase with income.
Mathematical Formulas/Models
The tax calculation model for the additional rate can be summarized as:
Where:
- Base Tax = Tax applicable up to the threshold
