The term "head tax" has several synonyms, including poll tax, capitation tax, and per capita tax. These taxes are levied on individuals rather than on their property or income. Poll tax is a term commonly used in the United States to refer to the head tax, which was abolished due to its discriminatory nature. The capitation tax is a fixed amount that is imposed on each individual. In contrast, the per capita tax is based on the income or wealth of each individual. These terms are frequently used interchangeably, but it is important to note their specific meanings and contexts in relation to taxation.
