What is the primary function of the IRS?

The primary function of the IRS, or Internal Revenue Service, is to collect federal taxes and enforce tax laws. This role is critical for the functioning of the government as it ensures that tax revenues are gathered in a fair and efficient manner, allowing for the funding of various public services and programs. The IRS is responsible for processing tax returns, conducting audits, and providing guidance and enforcement regarding compliance with tax laws. This function is crucial for maintaining the integrity of the tax system and ensuring that taxpayers fulfill their responsibilities under the law.

Other options do not align with the core mission of the IRS. For instance, overseeing national security is typically the role of agencies like the Department of Homeland Security and the Department of Defense. Educating the public on financial literacy, while important, is not a direct function of the IRS; instead, other organizations and agencies typically tackle financial education. Regulating international trade falls under the purview of other governmental divisions, such as the Department of Commerce, rather than the IRS.
