The Department operates and maintains systems that are critical to the nation’s financial infrastructure, such as the production of coin and currency, the disbursement of payments to the American public, revenue collection, and the borrowing of funds necessary to run the federal government. Its duties include advising on national and international financial, tax, and trade policies, collecting taxes, and investigating and prosecuting tax evaders.

The head of the department is the United States Secretary of the Treasury. The secretary is appointed by the president with the advise and consent of the senate.
