Tucker Act — Suing the Federal Government for Money Damages

The Tucker Act (28 U.S.C. § 1491) is the primary waiver of sovereign immunity that allows individuals and companies to sue the United States for money damages in the U.S. Court of Federal Claims. The federal government cannot be sued without its consent — a principle called sovereign immunity (see also Eleventh Amendment for the state-level equivalent) — and the Tucker Act, originally enacted in 1887, provides that consent for claims founded on the Constitution, federal statutes, executive regulations, or express or implied contracts with the United States. If the government owes you money — because it breached a contract, took your property without just compensation, overcharged your taxes, or violated a statute that mandates payment — the Tucker Act is typically the legal vehicle for recovering it. The Court of Federal Claims handles approximately 15,000–18,000 cases per year, including government contract disputes, tax refund suits, Fifth Amendment takings claims, military pay disputes, patent infringement by the government, and Indian tribal claims. Claims over $10,000 go to the Court of Federal Claims; claims of $10,000 or less can be filed in federal district court under the Little Tucker Act (28 U.S.C. § 1346(a)(2)).

Current Law (2026)

Legal Authority

• 28 U.S.C. § 1491(a) — Jurisdiction of the Court of Federal Claims (jurisdiction over claims against the United States founded on the Constitution, acts of Congress, regulations, or contracts — both express and implied — for liquidated or unliquidated damages in cases not sounding in tort)
• 28 U.S.C. § 1491(b) — Bid protest jurisdiction (the Court of Federal Claims has jurisdiction over bid protests — challenges to federal procurement actions — and may award injunctive and declaratory relief)
• 28 U.S.C. § 1346(a)(2) — Little Tucker Act (federal district courts have concurrent jurisdiction with the Court of Federal Claims for claims against the United States not exceeding $10,000)
• 28 U.S.C. § 2501 — Statute of limitations (claims must be filed within 6 years of accrual)
• 28 U.S.C. § 2502 — Aliens' privilege to sue (citizens of foreign governments that allow Americans to sue may bring Tucker Act claims)

How It Works

The United States cannot be sued unless it consents. The Tucker Act (28 U.S.C. § 1491) provides that consent for money claims — but the Act itself doesn't create a right to payment; it only supplies the jurisdictional hook. You still need a separate "money-mandating" source of law (a statute, regulation, or contract) that independently obligates the government to pay. The most common Tucker Act cases are government contract disputes (the government breached a contract for goods, services, or construction, typically under the Contract Disputes Act), tax refund suits (the IRS wrongly denied a refund after you've exhausted administrative remedies), Fifth Amendment takings claims (the government took your property or imposed regulations so restrictive they constitute a taking without just compensation), military and civilian pay disputes (wrongful discharge, denied promotion, or underpayment), patent infringement by the government (28 U.S.C. § 1498), and Indian tribal breach-of-trust claims. All of these claims go to the U.S. Court of Federal Claims in Washington, D.C. — a specialized Article I court with 16 presidentially appointed judges serving 15-year terms; appeals go to the Federal Circuit.

Two structural rules shape when and where Tucker Act claims can be brought. Claims exceeding $10,000 must go to the Court of Federal Claims; claims of $10,000 or less can be filed in your local federal district court under the Little Tucker Act (28 U.S.C. § 1346(a)(2)) — a significant convenience, but if you file in district court and your claim turns out to exceed $10,000, the excess is waived. The statute of limitations is 6 years from accrual (28 U.S.C. § 2501): typically when you knew or should have known the government owed you money and refused to pay — when the government breaches a contract, or when a taking becomes final. The Court of Federal Claims strictly enforces this limit. Finally, the Tucker Act explicitly excludes cases "sounding in tort" — negligence, property damage, and medical malpractice against the government go under the Federal Tort Claims Act (28 U.S.C. §§ 2671–2680), not here; if you file a tort claim under the Tucker Act by mistake, it will be dismissed for lack of jurisdiction.

How It Affects You

If you're a government contractor with a claim: The Tucker Act (28 U.S.C. § 1491) is the jurisdictional vehicle, but the Contract Disputes Act (CDA, 41 U.S.C. §§ 7101–7109) is the mandatory process. You cannot go straight to the Court of Federal Claims — you must follow the CDA sequence first.

Step 1: Submit a written claim to your contracting officer. For claims over $100,000, you must certify the claim as required by 41 U.S.C. § 7103(b) — stating that the claim is made in good faith, the amount accurately reflects what the government owes, and supporting data are accurate and complete. Missing or defective certification is a jurisdictional defect that can get your CFC case dismissed.

Step 2: Await or compel the Contracting Officer's Final Decision (COFD). The contracting officer has 60 days to issue a COFD on claims over $100,000. If 60 days pass without a decision, you can treat that as a deemed denial and appeal immediately. Once the COFD issues, you have 12 months to appeal to the Court of Federal Claims or an agency Board of Contract Appeals (Armed Services BCA for Defense contracts; Civilian BCA for most civilian agencies). This 12-month deadline is strictly enforced.

The Tucker Act's unique power in contracts: The court can hear not just express-contract claims but also implied-in-fact contracts — situations where the government's conduct creates a binding obligation even without a signed contract. This matters in pre-award situations, oral representations by contracting officials, and course-of-dealing disputes. The implied-in-fact contract theory requires: mutual intent to contract, consideration, and authority of the government official to bind the government (a critical limitation — only warranted contracting officers can bind the United States).

Bid protests: Tucker Act § 1491(b) gives the Court of Federal Claims bid protest jurisdiction — not just money, but injunctive relief and declaratory judgments to halt or redo a procurement. If you lost a competitive award you believe was handled improperly, you can protest to GAO (within 10 days of award or knowledge of basis) or to the CFC (no hard deadline but faster decisions favor promptness). CFC bid protests allow more discovery than GAO protests and can result in contract recompetition, stay of performance, or award cancellation.

6-year statute of limitations: Tucker Act claims must be filed within 6 years of accrual (28 U.S.C. § 2501). For contract claims, accrual typically occurs when the government's breach occurs — not when you discover it. For termination-for-convenience disputes, accrual runs from the termination settlement. Missing this deadline is fatal and cannot be equitably tolled.

If you're a property owner pursuing a takings claim: The Tucker Act is the path to just compensation under the Fifth Amendment when the government takes your property without paying you adequately — or at all. But the substantive takings doctrine controls whether a taking occurred; the Tucker Act only provides the court to adjudicate it.

The Supreme Court recognizes three types of takings, each with different legal tests:

Physical taking (government physically occupies or destroys your property): compensation is fair market value at the time of the taking. Accrual for the 6-year SOL runs from when the taking first occurs. For permanent flooding cases (Arkansas Game and Fish Commission v. United States, 2012), each seasonal flooding event may restart the limitations period.

Per se regulatory taking (Lucas v. South Carolina Coastal Council, 1992): when a regulation eliminates all economic value of your property — you're left with land worth nothing — the government owes compensation without further balancing. Courts require genuine elimination of economic value, not just significant reduction.

Penn Central regulatory taking (Penn Central Transportation Co. v. New York City, 1978): when a regulation doesn't eliminate all value but imposes a severe burden, courts balance three factors: (1) economic impact on the claimant, (2) extent to which the regulation interferes with distinct investment-backed expectations, and (3) character of the government action. This is the most litigated and fact-intensive test.

Temporary regulatory taking (First English Evangelical Lutheran Church v. County of Los Angeles, 1987): if a regulation temporarily prohibited all economic use and was later withdrawn, the government owes compensation for the period of denial. This matters for environmental regulations, wetland designations, and coastal regulations that are later struck down or narrowed.

Practical steps: File in the Court of Federal Claims for claims over $10,000; district court (Little Tucker Act) for $10,000 or less. You cannot get an injunction in the CFC to stop the taking — the remedy is money only. No punitive damages are available. Attorney fees are generally not recoverable unless the Equal Access to Justice Act applies. The 6-year SOL runs from when the taking becomes "final" — often when administrative appeals are exhausted, not when the regulation was enacted.

If you're a taxpayer seeking a refund after IRS denial: After the IRS denies your administrative refund claim, you have two forum choices and a specific limitations period:

Forum choice: File in the Court of Federal Claims (Washington, D.C.; no jury; specialized tax judges) or in your local federal district court (jury trial available; may be more accessible). For complex legal questions about tax law, CFC's specialized expertise is typically preferred. For disputes turning primarily on credibility or sympathetic fact patterns, district court's jury option can matter. Both courts apply the same substantive tax law.

Limitations period: 2 years from the date the IRS mails you notice of disallowance of your refund claim (not 6 years — the tax refund SOL is shorter under 26 U.S.C. § 6532). Missing this window bars your claim permanently.

Prerequisite: You must have paid the disputed tax, filed an administrative refund claim with the IRS, and had that claim denied. You cannot sue in the Tucker Act forum without paying first — the "full payment rule" (Flora v. United States, 1960). For the Little Tucker Act ($10,000 or less), you can bring the suit in district court after IRS denial.

If you're a federal employee or military member with a pay dispute: Tucker Act jurisdiction covers pay claims when a statute mandates the payment the government withheld — this is the "money-mandating" requirement that is frequently litigated.

The Back Pay Act (5 U.S.C. § 5596) makes pay claims for civilian federal employees money-mandating under the Tucker Act — if you were wrongfully furloughed, improperly demoted, or had pay withheld contrary to OPM regulations, the Back Pay Act creates an enforceable right. Military pay statutes similarly mandate payment, making wrongful discharge, improper rating, or denied allowance claims Tucker Act-viable.

But the Tucker Act has a critical limitation in the employment context: it can award back pay but not reinstatement. If you want your job back, you need a separate route — Merit Systems Protection Board (MSPB) appeal, EEOC complaint, or district court suit under Title VII/ADEA/Rehabilitation Act. Many employees pursue both paths: MSPB for reinstatement, CFC for back pay.

The money-mandating trap: Not every federal statute creates a Tucker Act claim even if it involves money. The statute must be "money-mandating" — it must fairly be interpreted as requiring the government to pay identified claimants. Discretionary grant programs, advisory pronouncements, and "may pay" statutes don't qualify (Navajo Nation v. United States, 2003; Fisher v. United States, 2011). If you're considering a Tucker Act claim based on a statutory right to payment, have a government contracts attorney analyze whether the specific statute qualifies — this is a threshold jurisdictional question, not a merits question, and getting it wrong means your case is dismissed.

Tucker Act vs. Federal Tort Claims Act: If the government injured you through negligence — a government vehicle hit your car, a federal doctor committed malpractice, a postal worker damaged your property — that's a tort claim and goes under the Federal Tort Claims Act (28 U.S.C. §§ 2671–2680), not the Tucker Act. The FTCA requires you to file an administrative claim (SF-95) with the agency first and wait 6 months before suing in federal district court. Tucker Act claims have no such administrative prerequisite (except for CDA contracts). The Tucker Act explicitly excludes cases "sounding in tort" — if your claim sounds like negligence or intentional wrongdoing rather than breach of contract or taking, you're in the wrong statute.

State Variations

The Tucker Act is exclusively federal:

• State governments have their own sovereign immunity rules and court of claims systems
• Most states have waived sovereign immunity for contract claims through state court of claims statutes
• State takings claims are handled in state courts under state constitutional provisions
• The Tucker Act has no state equivalent — it is specific to claims against the United States

Implementing Regulations

• 28 USC 1491 — The Tucker Act itself serves as the jurisdictional statute for the U.S. Court of Federal Claims; it does not have extensive implementing regulations
• Rules of the U.S. Court of Federal Claims (RCFC) — procedural rules governing Tucker Act litigation (filing, discovery, trial, judgment, appeals)
• 28 CFR Part 14 — DOJ administrative claims under the Federal Tort Claims Act (related but distinct from Tucker Act — FTCA claims are handled separately)

Pending Legislation

No standalone Tucker Act reform bills have been introduced in the 119th Congress. Claims against the government appear in broader judiciary legislation — see Federal Tort Claims Act.

Recent Developments

The Court of Federal Claims has seen increased activity in government contract disputes (particularly in IT and defense procurement), vaccine injury claims, and takings cases related to environmental regulations and border wall construction. The court's bid protest jurisdiction (added in 1996) has become a significant alternative to GAO for challenging contract awards. Prevailing parties in Tucker Act litigation may also recover attorney fees under the Equal Access to Justice Act. The Federal Circuit's interpretation of what constitutes a "money-mandating" statute continues to shape Tucker Act jurisdiction — recent decisions have addressed whether various benefit statutes create enforceable payment obligations.
