Answer:
Option C- An income tax is progressive if the percentage of income paid as taxes increases as income increases.
Explanation:
Majorly, there are three types of Tax systems; these are: Progressive, regressive and proportional.
A tax in which the tax rate increases as the taxable amount increases is known as a progressive tax.
The term "progressive" refers to the way the tax rate progresses from low to high, such that a taxpayer's average tax rate is less than the person's marginal tax rate.
Also,a progressive tax is applicable to individual taxes or to a tax system as a whole; a year, multi-year, or lifetime. It is imposed with the aim of reducing the tax incidence of people with a lower ability to pay, as such taxes shift the incidence increasingly to those with a higher ability-to-pay.
Thus, an income tax is progressive if the percentage of income paid as taxes increases as income increases.
