Statute of limitations for fraud in United States Federal

Rule or statute summary

Fraud claims in United States federal court don’t have one universal “statute of limitations.” The deadline depends on which federal statute (or fraud-based federal theory that borrows another limitations rule) you’re using and, in many cases, when the fraud was discovered (or should have been discovered).

DocketMath’s statute-of-limitations calculator is designed around the main timing patterns federal law uses for fraud-like claims:

• Express statutory limitations periods: Many federal fraud causes of action include a limitations period stated directly in the federal code (often 2–6 years, depending on the statute).
• Discovery-style triggers: Certain fraud statutes start the clock when the fraud is discovered (or when it should have been discovered). This can delay the filing deadline compared with a strict “date of act” rule.
• Longer / special clocks for fraud against the government: The False Claims Act (FCA) has its own limitations framework that frequently turns on discovery and includes special statutory ceilings.

Practical mapping: “Which fraud?”

Use this checklist to decide what the calculator should be set to:

• ☐ Securities fraud (for example, claims under Rule 10b-5 / Exchange Act theories)
• ☐ Wire/mail fraud theories (often discussed in criminal contexts; civil limitations can differ)
• ☐ False Claims Act (fraudulently submitting claims or statements to the U.S. government)
• ☐ Common-law fraud (generally state law; if your claim is truly common-law fraud, the federal court typically applies the state limitations period rather than a federal one)

Because you asked specifically about United States Federal, the rest of this post focuses on federal causes of action that contain their own limitations language.

Note (not legal advice): This is informational only. The “right” deadline can change based on the exact claim, whether it’s civil vs. criminal, and what facts support when discovery occurred.

1) False Claims Act (FCA) — 31 U.S.C. § 3731(b) (civil “fraud on the government”)

If you mean fraud involving submitting false statements/claims to the U.S. government, the FCA is often the central federal statute. The civil timing provisions are in:

• 31 U.S.C. § 3731(b)(1)

  • Provides a 6-year limitations period for certain civil FCA actions, measured from the relevant statutory starting point.
  • Also includes a 10-year ceiling for certain FCA actions tied to specific kinds of conduct, with the statute structuring how the limitations period operates.
• 31 U.S.C. § 3731(b)(2)

  • For certain FCA actions, the statute incorporates a discovery concept (i.e., the period runs based on when the fraud was discovered or should have been discovered, depending on the subsection’s terms and the claim’s structure).

Statutory anchor: **31 U.S.C. § 3731(b)

In practice, DocketMath inputs commonly track (1) the first alleged false submission and (2) the relevant discovery date(s), because FCA timing is frequently litigated around when the claim became or should have become discoverable.

2) Securities fraud — 28 U.S.C. § 1658(b) (discovery + outer cap for certain private actions)

For many federal securities “fraud” claims, Congress provided a specialized limitations provision in Title 28:

• 28 U.S.C. § 1658(b)

  • Establishes a 2-year limitations period framework and a separate 5-year outer limit (often described as a statute of repose) for certain private actions involving fraud.

A common practical reading of the structure is:

• Start (limitations side): tied to discovery (or when discovery should have occurred, depending on how the claim is framed under the statute).
• Cap (repose side): a maximum time after the violation such that late-discovered claims may still be barred.

3) Federal criminal fraud (context-only) — different regime than civil

You may see “fraud” discussed alongside criminal statutes such as 18 U.S.C. § 1343 (wire fraud) or 18 U.S.C. § 1341 (mail fraud). However, criminal fraud limitations are governed by a different statute (for example, 18 U.S.C. § 3282) and may include different tolling rules and time calculations than civil fraud causes of action.

Key point: Don’t assume one civil fraud deadline applies to a criminal fraud case (or vice versa). DocketMath users typically focus on the civil timing rules for FCA or securities claims.

Step-by-step inputs (what to enter)

DocketMath’s calculator workflow generally relies on the following types of inputs:

1. **Cause of action / claim type (federal)

   • ☐ **FCA (31 U.S.C. § 3731(b))
   • ☐ **Securities-fraud framework (28 U.S.C. § 1658(b))
2. Date of the first alleged violation

   • Often the first false statement/claim submission (FCA) or the first misleading act tied to the securities theory.
3. Discovery date (if the rule is discovery-based)

   • This is the date the fraud was actually discovered, if known.
4. “Should have discovered” alternative date (if your facts support it)

   • If the exact discovery date is unclear, you may enter the best-supported alternative date based on what reasonable diligence would have revealed (as reflected in your record).

How outputs change (what to expect)

The most common pattern in DocketMath results is that:

• Discovery-based rules can push the deadline later because the clock starts when the fraud was (or should have been) discovered.
• Outer caps / statutes of repose can still bar the claim even if discovery happened later—meaning improving the discovery story might not overcome the outer deadline.

A quick example of how to read the output

After you input dates, DocketMath will typically show:

• the calculated expiration date (or a filing-bar conclusion),
• and a breakdown of how much the discovery timing affects the result.
