Tax law deals with the constitutional, common-law, statutory, tax treaty, and regulatory rules that constitute the law applicable to taxation.
Tax covers the rules, policies and laws that oversee the tax process, which involves charges on estates, transactions, property, income, licenses and more by the government. Taxation also includes duties on imports from foreign countries and all compulsory levies imposed by the government upon individuals for benefit of the state.
The intricate body of tax law covers payment of taxes to a minimum of four levels of government, either directly or indirectly. There is a seemingly endless list of entities that create and enforce tax laws and collect tax revenues. They range from the local government level, such as cities and other municipalities, townships, districts and counties to regional, state and federal levels. They include agencies, transit districts, utility companies, and schools, just to name a few.
