A statutory period is a deadline set by law for taking a specific legal action, whether that means filing a lawsuit, bringing criminal charges, submitting an administrative claim, or auditing a tax return. Miss the window and the right to act usually disappears, no matter how strong the underlying case. Lengths range from 45 days for certain federal employment complaints to no limit at all for the most serious crimes. Knowing which deadline applies to you, when it started running, and what might pause it often decides whether a claim survives.
Where These Deadlines Come From
Statutory periods are written by legislatures, not judges. Congress and state lawmakers put specific timeframes into statutes so the rules are set before a dispute arises, and courts generally cannot extend them just because a case looks sympathetic.
At the federal level, 28 U.S.C. ยง 1658 sets a default four-year window for civil suits arising under any Act of Congress that doesn’t specify its own deadline.1Office of the Law Revision Counsel. 28 USC 1658 – Time Limitations on the Commencement of Civil Actions Arising Under Acts of Congress Many federal statutes override that default with shorter or longer periods tailored to the subject matter. State legislatures do the same for state-law claims, which is why a car accident lawsuit deadline depends on where the accident happened.
When the Clock Starts
The moment a statutory period begins ticking is called accrual. For most claims, accrual happens on the day the harmful event occurs or a contract is broken. A fender bender on March 1 starts the personal injury clock on March 1.
The picture gets more complicated when the harm isn’t obvious right away. Under the discovery rule, the clock doesn’t start until you know, or reasonably should know, that you’ve been harmed. If a financial advisor has been skimming your account for years, the period starts when you first see a statement that reveals the loss, not when the skimming began. The key question is when you had enough information to suspect something was wrong. Document both the date of the incident and the date you learned about it. That timeline protects you if a defendant later argues you waited too long.
Statute of Limitations vs. Statute of Repose
People use “statute of limitations” and “statutory period” interchangeably, and in casual conversation that’s fine. The law, though, draws a sharp line between a statute of limitations and a statute of repose, and the difference matters.
A statute of limitations runs from the date of injury or discovery, and it can usually be paused for reasons like the victim being a minor or the defendant hiding from service. A statute of repose runs from an earlier fixed event, such as the date a product was manufactured or a building was completed, and it generally cannot be paused for any reason. Even if you had no way of knowing you were harmed, the deadline still expires on schedule.
The General Aviation Revitalization Act is a clear example. It bars lawsuits against aircraft manufacturers when the accident happened more than 18 years after the plane was first delivered to a buyer.2GovInfo.

Typical Lengths by Type of Claim
Personal Injury and Contracts
Deadlines for personal injury lawsuits range from one to six years depending on the state, with two years being the most common. Written contract claims tend to be longer, usually four to ten years. Oral contract disputes typically get a shorter period than written ones because of the difficulty of proving what was agreed. These ranges are generalizations, so the specific deadline depends on your state and the type of claim.
Federal Criminal Prosecution
The federal government generally has five years from the date of a non-capital offense to bring charges.3Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Specific statutes override that default for particular crimes. Tax evasion carries a six-year window, and certain terrorism and financial fraud offenses have longer periods. Capital offenses have no deadline at all. The government can prosecute at any time.4Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses
IRS Tax Assessment
The IRS generally has three years from the date you file a return to assess additional tax or begin an audit. That window stretches to six years if you leave out more than 25 percent of your gross income.5Office of the Law Revision Counsel. 26 USC 6501 – Limitations on Assessment and Collection If you file a fraudulent return or never file at all, the IRS faces no time limit whatsoever. This is one of the few areas where the government’s clock never runs out.
Administrative Deadlines You Must Meet Before Suing
Some statutory periods aren’t about filing a lawsuit. They govern a required step you have to complete before you’re even allowed to sue, and skipping these prerequisites is one of the most common ways people lose otherwise viable claims.
If you’re injured by a federal employee acting in their official capacity, you can’t go straight to court. The Federal Tort Claims Act requires you to submit a written claim to the responsible agency within two years of the incident. If the agency denies your claim, you then have six months from the date of the denial letter to file suit.6Office of the Law Revision Counsel. 28 USC 2401 – Time for Commencing Action Against United States If the agency sits on your claim for more than six months without responding, you can treat the silence as a denial and proceed to court.
Employment discrimination works similarly. You generally have 180 days from the discriminatory act to file a charge with the Equal Employment Opportunity Commission. That window extends to 300 days if your state has its own anti-discrimination enforcement agency, which most do. Federal employees face a tighter timeline of 45 days to contact their agency’s EEO counselor.7U.S. Equal Employment Opportunity Commission. Time Limits for Filing a Charge In harassment cases, the deadline runs from the last incident of harassment, not the first.
What Can Pause or Extend the Clock
Certain circumstances temporarily stop a statutory period from running, a concept called tolling. When the condition that caused the pause ends, the clock picks up where it left off. It doesn’t reset to zero.
Statutory Tolling
Legislatures build tolling provisions directly into statutes for situations they’ve anticipated. The most common involve:
- Age. If the person with the legal claim is a minor, the clock typically stays paused until they turn 18.
- Mental incapacity. If someone cannot understand their legal rights when the claim arises, the period pauses until the incapacity lifts.
- An absent defendant. If the person you need to sue leaves the state or actively hides to avoid service, many states pause the clock for the duration of the absence.
- Military service. Under the Servicemembers Civil Relief Act, time spent on active duty doesn’t count toward any statutory period in a civil case brought by or against the servicemember. The protection extends to real property redemption periods but does not apply to federal tax deadlines.8Office of the Law Revision Counsel. 50 USC 3936 – Statute of Limitations
Equitable Tolling
Even when no statute specifically authorizes a pause, courts can sometimes extend a deadline through equitable tolling. This is a judge-made safety valve, and courts apply it sparingly. You generally must show two things: that you pursued your rights with reasonable diligence throughout the period, and that extraordinary circumstances beyond your control prevented you from filing on time. A lawyer’s mistake, a medical emergency, or active deception by the opposing party might qualify. Simply not knowing the deadline existed almost never does. Statutes of repose, unlike statutes of limitations, are not subject to equitable tolling at all.
What Happens When the Deadline Passes
Expiration of a statute of limitations doesn’t erase the claim from existence. It creates a defense that the opposing party must actually raise. Under the Federal Rules of Civil Procedure, the statute of limitations is listed as an affirmative defense that a defendant must assert in their responsive pleading, and a defendant who fails to raise it can waive it entirely.9Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading
In practice, though, competent defendants and their attorneys almost always raise the defense. When they do, the court will dismiss the case regardless of how strong the underlying evidence is. For government enforcement actions, an expired period means the agency loses its ability to prosecute, collect, or assess. The practical effect is close to absolute even though it technically depends on someone invoking the defense.
Protecting Yourself From a Missed Deadline
Identify the applicable deadline early. The period that governs your situation depends on the type of claim, the jurisdiction, and whether any administrative prerequisites apply before you can file suit. Getting the wrong answer on any of those variables can cost you the entire case.
Document everything with dates. Record when an incident occurred, when you first discovered the harm, and when you took each step in the process. If tolling might apply, keep evidence of the condition that paused the clock. A minor’s birth certificate, military orders, or medical records documenting incapacity can all become critical if a defendant later challenges your timeline.
Treat every deadline as if it cannot be extended, because in many cases it truly cannot. Statutes of repose are immune to tolling. Administrative prerequisites like the FTCA’s two-year claim requirement and the EEOC’s charge-filing window are notoriously unforgiving. Courts are far more sympathetic to someone who filed early and made a procedural error than to someone who waited until the last possible day only to find the deadline had already passed.
