Anti-Deficiency Act

The Anti-Deficiency Act prohibits federal agencies from obligating or expending funds in excess of the amount appropriated by Congress, with violations carrying personal civil and criminal penalties for responsible officials.

Quick answer

The Anti-Deficiency Act prohibits federal agencies from obligating or expending funds in excess of the amount appropriated by Congress, with violations carrying personal civil and criminal penalties for responsible officials.


The Anti-Deficiency Act is the primary federal law prohibiting government officials from spending or committing to spend money in excess of available appropriations, making it a personal liability for the contracting officials involved rather than merely an institutional failure.

What is the Anti-Deficiency Act (ADA)?

The Anti-Deficiency Act (31 U.S.C. §§ 1341-1342, 1511-1519) prohibits federal employees from:

  1. Making or authorizing an obligation or expenditure that exceeds the amount available in the appropriation for that purpose.
  2. Making or authorizing an obligation in advance of an appropriation (unless specifically authorized by law).
  3. Accepting voluntary services (i.e., directing someone to work without pay) when the funds to pay for those services are not available.

The consequences of an ADA violation are significant and personal:

  • Administrative penalties: ADA violations must be reported to the President, Congress, and the Comptroller General. The responsible official may face suspension or removal from federal service.
  • Civil penalties: Officials who willfully violate the ADA face fines of $5,000 to $50,000.
  • Criminal penalties: Officials who knowingly and willfully violate the ADA face criminal prosecution with fines and up to two years imprisonment.

Common causes of ADA violations in contracting:

  • Awarding a contract that exceeds available appropriations.
  • Exercising a contract option when the funds for the option period have not been appropriated.
  • Incrementally funding a fixed-price contract below the full amount without a limitation of funds clause.
  • Using expired or cancelled appropriations for new obligations.
  • Modifying a contract to add scope when the funds for the modification are not available.

Why the Anti-Deficiency Act matters for government contractors

While ADA violations are personal offenses of government employees, they directly affect contractors when the government disavows contracts or modifications awarded in violation of the ADA. A contract awarded without valid appropriations is voidable - the government may terminate the contract and resist payment, leaving the contractor with delivered work but no contract remedy. Contractors should verify funding availability and cite specific appropriation lines before committing to work.

Example

A program office urgently needs an IT modernization modification worth $3.2 million. The contracting officer checks the available balance and believes $3.2 million is available. She awards the modification. Post-award accounting reveals that prior obligations had already consumed $1.1 million of the available balance, leaving only $2.1 million. The $1.1 million excess obligation is an ADA violation. The contracting officer must report the violation to the agency Inspector General and Treasury. She works with the budget office to obtain a reprogramming or supplemental appropriation to cure the violation. The contractor's work continues but payment on the excess amount is delayed pending resolution.

Frequently Asked Questions

What is the difference between an obligation and an expenditure?


An obligation is the legal commitment of the government to pay - signing a contract creates an obligation. An expenditure (outlay) is the actual disbursement of funds to the contractor. The ADA prohibits exceeding appropriation limits at both stages: you cannot obligate more than is appropriated, and you cannot pay out more than was obligated.

Can an ADA violation be cured?


Yes. Minor ADA violations (particularly those involving good faith errors rather than willful action) can sometimes be cured through retroactive reprogramming or supplemental appropriations. The agency must still report the violation and implement corrective actions, but cure reduces the personnel consequences for the responsible official.

Are contractors liable for their role in an ADA violation?


Generally no. The ADA is directed at government employees, not contractors. A contractor who receives a validly-awarded contract and performs is generally entitled to payment even if there is a later question about appropriation sufficiency, provided the contractor was not complicit in creating the improper obligation.

Does the ADA apply to government credit card (purchase card) purchases?


Yes. Purchase card holders are subject to the same ADA constraints as contracting officers. Using a purchase card to obligate more than is available in the applicable account is an ADA violation, even though the mechanism is a credit card rather than a contract document.
