On September 2, 1789, during its early session, Congress passed an act establishing the Department of the Treasury as one of the nation’s first executive departments. The legislation laid out a clear organizational structure: a Secretary of the Treasury (as department head), Comptroller, Auditor, Treasurer, Register, and an Assistant to the Secretary, to be appointed by the Secretary.
In the early years of the United States, fiscal stability was paramount. Many of the Treasury’s functions—financing war, managing revenue, and keeping accounts—were already being handled informally even before the Declaration of Independence. However, recognizing the necessity for formal financial governance under the new federal framework, the First Congress acted swiftly.
Shortly thereafter, on September 11, 1789, Alexander Hamilton, a Founding Father with experience as George Washington’s aide-de-camp and instrumental in the Constitution’s ratification, took the oath as the nation’s first Secretary of the Treasury. Hamilton brought an ambitious vision: to create a strong central government with stable finances. He proposed funding through customs duties, advocated the establishment of a national bank, and laid the foundations for the federal assumption of state war debts.
The new Department’s responsibilities were extensive from the outset. The Secretary was charged with designing plans to improve and manage revenue, drafting estimates of public income and expenditures, overseeing revenue collection, establishing accounting forms and systems, and issuing warrants for funds based on congressional appropriations. At its core, the Department anchored the young republic’s financial system, underpinning everything from fiscal order to building public credit.
Over time, the Treasury’s role broadened significantly—evolving from revenue collection and account-keeping to regulating national banks, printing currency, issuing securities, and shaping economic policy.
Yet, its inception in 1789, driven by Hamilton’s leadership and Congress’s foresight, marked a defining moment: the U.S. firmly committed to structured, centralized financial governance. The Department of the Treasury did more than manage money—it helped cement the foundation of the American republic.
