If, as your taxable income decreases, you pay a smaller percentage of your taxable income in taxes, then the tax is Progressive tax.

<h3>What is meant by progressive taxes?</h3>

The average tax burden rises with income under a progressive tax. Low- and middle-income taxpayers bear a disproportionately tiny amount of the tax burden, compared to high-income families. A tax system that raises rates as taxable income rises is known as a progressive tax. Taxes on investment income, interest income, rental income, estates, and tax credits are a few examples of progressive taxes.

Based on the amount of tax you must pay relative to your income, taxes can be classified as regressive, proportional, or progressive. As your income declines, regressive taxes force you to pay a bigger proportion of your individual income in taxes. Tax reductions enhance people' discretionary income while reducing the government's revenue. Tax reductions typically refer to decreases in the percentage of income, commodities, and services subject to tax. Tax reductions serve as an illustration of an expansionary fiscal strategy since they give consumers greater discretionary income.

So, If, as your taxable income decreases, you pay a smaller percentage of your taxable income in taxes, then the tax is Progressive tax.
