Implementing Decreases in Overall Government Expenditures Act or the Implementing DOGE Act This bill requires rescissions of certain nonsecurity (i.e., nondefense) discretionary appropriations. Beginning in FY2026, the bill requires annual rescissions on a pro rata basis that are equal to the excess growth percent of the nonsecurity discretionary appropriations made available for the fiscal year. Under the bill, the excess growth percent is the percentage in excess of 1% that the total annual appropriations exceeded the previous fiscal year’s annual appropriations. The rescissions required by the bill are effective on the day after the date on which appropriations are made available through September 30 of the applicable fiscal year for the entire federal government.
