Tax is a mandatory financial charge imposed by a government on individuals and businesses. It is used to fund public services such as education, healthcare, and infrastructure. Taxes can be collected in various forms, including income tax, sales tax, and property tax. The amount of tax owed typically depends on income level, property value, or the price of goods and services. Governments use tax revenue to maintain and improve community resources, ensuring that essential services are available to all citizens. Understanding taxes is important for responsible financial planning and civic engagement.
