Revenue agencies are government organizations responsible for collecting taxes and managing public revenue. They ensure that individuals and businesses comply with tax laws, which helps fund essential services like education, healthcare, and infrastructure. These agencies often conduct audits and provide guidance to taxpayers on their obligations. In many countries, revenue agencies also play a role in enforcing tax laws and preventing tax evasion. They may use various tools and technologies to track income and expenditures, ensuring that everyone pays their fair share. Examples of such agencies include the Internal Revenue Service (IRS) in the United States and Her Majesty's Revenue and Customs (HMRC) in the United Kingdom.
