Tax authorities are government agencies responsible for collecting taxes and enforcing tax laws. They ensure that individuals and businesses comply with tax regulations, which helps fund public services like education, healthcare, and infrastructure. These agencies also provide guidance on tax obligations and may conduct audits to verify compliance. In many countries, tax authorities are part of the Department of Revenue or Ministry of Finance. They handle various types of taxes, including income tax, sales tax, and property tax. Tax authorities also play a role in addressing tax fraud and ensuring fair tax practices among citizens and businesses.
