Treasury Department

The United States Department of the Treasury was a pre-War department of the United States government. The Department of the Treasury was a federal executive department responsible for the creation and distribution of the United States dollar, collection of taxes, and management the United States debt, among other duties.

Background
Any resident of Appalachia who won the Great Appalachian Sweepstakes were required to pay a gift tax. Failure to do so ran the risk of being reported to the Internal Revenue Service, the division of the Treasury Department responsible for tax collection and pursuing tax fraud.

The Secret Service, a division of the department tasked with protecting the nation's currency from counterfeiting as well as the leaders of government, appears in Fallout 76, introduced in the Wastelanders update. Shortly before the Great War, the United States gold reserves were emptied from Fort Knox and sent to Vault 79. Numerous members of the Secret Service were tasked with defending the stockpile.

When the Great War of 2077 broke out, the nuclear alarm system alerted the members of the Cabinet of the ensuing nuclear exchange and which government fallout shelter to take cover in. However, the system had been tampered with, with most of the members removed in questionable circumstances. The Secretary of the Treasury was one of the only cabinet members actually sent alerts, with orders to report to the Whitespring bunker alongside the Secretary of the Interior and Secretary of Agriculture Thomas Eckhart. With contact lost with Raven Rock as well as the president at Control Station ENCLAVE, the Treasury Secretary was next in line to become the acting president and leader of the Enclave within the bunker. However, Thomas Eckhart planned to take control himself in order to continue the War against China, and so had a few of his loyal subordinates isolate and execute the Secretary. Eckhart then gathered the occupants of the bunker and informed them of the loss of contact with the rest of the Enclave as well as the secretary's death of "radiation poisoning," claiming control for himself.
