The kind of tax that is progressive is federal income tax.
The kind of tax that is progressive is the federal income tax. To determine this, it's important to understand what a progressive tax system is. A progressive tax is a taxation method where the tax rate increases as the taxable amount or income increases. In other words, as a person earns more income, their tax rate also increases proportionally. The federal income tax in many countries, including the United States, follows a progressive tax structure. As individuals' income increases, they move into higher income tax brackets where they are subject to a higher tax rate. This means that higher-income individuals pay a larger share of their income in taxes compared to lower-income individuals.
