What are the subjective and objective approach to measure the ability to pay tax?

The subjective approach to measuring the ability to pay tax considers individual circumstances, such as personal wealth, income stability, and lifestyle, recognizing that different taxpayers may have varying capacities to contribute based on their unique situations. In contrast, the objective approach focuses on quantifiable metrics, such as income levels, assets, and economic indicators, providing a standardized method for assessing tax liability across individuals. Combining both approaches can offer a more comprehensive understanding of taxpayers' abilities to bear tax burdens.
