This document defines and explains different types of taxes. It begins by defining tax as a financial charge imposed by a state on taxpayers to fund government expenditures. It then distinguishes between direct and indirect taxes. Direct taxes are paid directly by individuals or organizations to the government, such as income tax and wealth tax, while indirect taxes increase the price of goods so consumers pay the tax. The document provides examples of indirect taxes like excise duty, VAT, sales tax, and service tax. It also defines key tax-related terms like assessment year, previous year, and person.
