Use-It-or-Lose-It Budgeting is annual appropriations force agencies to spend before fiscal year-end or lose future budget baseline. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0282, within the Government Perverse Pattern family. The core principle: annual appropriations force agencies to spend before fiscal year-end or lose future budget baseline. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Original analysis from The Incentives Lab — how this element behaves inside real payoff structures.
Why this element matters to incentive design
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: annual appropriations force agencies to spend before fiscal year-end or lose future budget baseline. You can recognize it in the field by its signature: september is the most expensive month in federal procurement. Every element in the Incentives dimension changes the perceived payoff of an action before the action happens, which is exactly where incentive design has leverage.
How it gets exploited
Left undesigned, budget mechanics produce spending mechanics. It is amplified whenever budget mechanics produce spending mechanics. Inside organizations that shows up as budget mechanics produce spending mechanics. The pattern is the same one Goodhart's Law describes: the measurable proxy attracts the effort, and the purpose behind it quietly loses funding.
How the Lab designs around it
The redesign move is to multi-year carryover authority. Outcome-based budgeting. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
