Which term refers to taxes on both earned and unearned income?

Income taxes are defined as taxes assessed on an individual's or entity's income, encompassing both earned income (such as wages, salaries, and tips) and unearned income (such as dividends, interest, and capital gains). This broad definition means that virtually all forms of income are subject to taxation under this category, making income taxes a primary source of revenue for governments.

While property taxes focus specifically on real estate ownership and sales taxes are levied on the purchase of goods and services, income taxes apply universally to various forms of income, highlighting their inclusive nature. Capital gains taxes specifically pertain to the profits from the sale of investments, which is a subset of unearned income, but do not cover earned income. Thus, income taxes are the best term to define the taxes on both earned and unearned income altogether.
