Tax Law is a branch of law that governs the assessment and collection of taxes by government entities. It encompasses the regulations and statutes that dictate how taxes are levied on individuals and businesses, including income tax, sales tax, property tax, and estate tax. Tax law is crucial for understanding taxpayers' rights and obligations, as well as the procedures for tax compliance, audits, and disputes. Additionally, it includes tax planning strategies and incentives that affect economic behavior, influencing decisions on investment, savings, and expenditures. Tax laws are subject to change and vary significantly between jurisdictions, making it an essential area of expertise for legal and financial professionals.
