What safeguard is in place to prevent violation of the Anti-Deficiency Act in contracts using incremental funding?

The safeguard to prevent violation of the Anti-Deficiency Act in contracts using incremental funding is the limitation of costs incurred to the amount allotted for a contract. This is crucial because the Anti-Deficiency Act prohibits federal agencies from obligating or spending more funds than what has been appropriated by Congress. Incremental funding allows a contract to be funded in increments, but agencies must ensure that they do not exceed the total funding amount that has been allotted at any given time. By restricting costs to the appropriated amounts for each funding increment, agencies ensure compliance with legal requirements and avoid unauthorized expenditures. This practice maintains fiscal responsibility and ensures that agencies operate within the constraints of their budgets while also fulfilling contract obligations efficiently.
