A statute of limitations is a law that sets the maximum period after an event, such as an injury, a breach of contract, a missed payment or a crime, during which legal proceedings can be started. Once that period runs out, the claim is generally barred: a court will dismiss a lawsuit filed too late, and prosecutors can no longer bring charges for an offense whose time limit has expired. The length of the period depends on the type of claim and on the jurisdiction whose law applies.

What a Statute of Limitations Means

These laws exist in both civil and criminal law:

• Civil cases: lawsuits between private parties, such as personal injury, medical malpractice, breach of contract, property damage and debt collection. Most limitation periods fall in this category.
• Criminal cases: the deadline by which the government must file charges. Less serious offenses usually have shorter periods, the most serious often have none.

The rule is set by statute. Each U.S. state sets its own periods for claims under state law, and Congress sets periods for federal crimes and federal causes of action. Which period applies depends on which law governs the claim, and that can involve a choice between states when the parties, the contract and the events are in different places.

How a Statute of Limitations Works

Every limitation period has three parts: when the clock starts, how long it runs, and whether anything pauses or extends it.

When the clock starts

The start date is called accrual. For many claims it is the date of the harmful act, such as the date of a car accident. For a breach of contract it is usually the date of the breach. For consumer debt, depending on the state, the clock may start on the date the debt was incurred or the date a payment was missed.

Some claims use a discovery rule, which starts the clock when the injured person discovered the harm, or reasonably should have discovered it. This matters for injuries that are not obvious right away, such as a surgical error that shows up months later or a fraud that stays hidden.

How long it runs

The period itself is set by statute and varies widely. A few examples drawn from U.S. law:

• Medical malpractice: generally one to four years, depending on the state. Texas, for instance, gives claimants two years to file a health care liability claim.
• Consumer debt: usually three to six years, though some states and debt types allow up to 15 years. Florida’s period for debt on a written contract is five years.
• Federal crimes: the general federal limit for non-capital offenses is five years unless a specific statute provides otherwise. Capital offenses, such as capital murder, have no limitation period.
• Negligence in Florida: the state cut the period for general negligence claims from four years to two years in 2023, for incidents occurring after the change took effect.

Even within one state, the period can differ for oral contracts, written contracts, promissory notes and open accounts like credit cards.

What can pause or extend it

Tolling stops the clock temporarily. Common grounds include the claimant being a minor, the defendant leaving the jurisdiction or concealing the wrong, and certain bankruptcy proceedings, although the exact grounds depend on the jurisdiction. When the reason for tolling ends, the clock resumes rather than resetting.

Some laws also add time when new evidence emerges. In California, for most sex offenses, the limitation period can be extended by one year from the date DNA evidence identifies a suspect.

Interpreting the deadline in a real case

In a civil case, the statute of limitations is generally an affirmative defense: the defendant must raise it, typically early, or may lose it, and a court usually will not apply it on its own initiative. That is one reason a debt collector might sue on an old debt: if the consumer does not respond, the court may enter a default judgment even though the claim was time-barred.

The deadline is measured to a filing. A demand letter or negotiations do not, by themselves, stop the clock in most situations; the case or charges must be filed with the court before the period ends.

Statutes of Limitations for Crimes

Criminal limitation periods usually scale with seriousness. Misdemeanors tend to have short windows, many felonies longer ones, and the gravest crimes none at all.

Is there a statute of limitations on murder?

In the United States, murder generally has no statute of limitations, at the federal level or in the states. A homicide can be charged decades later if evidence identifies a suspect. Lesser homicide charges, such as some forms of manslaughter, can have limitation periods in certain states, so the answer depends on how the killing is charged and where.

Many states also remove the time limit for other serious offenses, such as sex offenses involving minors and violent crimes like kidnapping or arson. California abolished the limitation period for almost all felony-level sex offenses in 2016, though some specific offenses still carry a deadline. Other states set periods of 10 to 20 years or more for the most serious sex crimes instead.

International law

Under international agreements, including the UN Convention on the Non-Applicability of Statutory Limitations to War Crimes and Crimes Against Humanity and the Rome Statute of the International Criminal Court, war crimes, crimes against humanity and genocide are not subject to any limitation period.

In the U.S., the War Crimes Act of 1996 imposes criminal penalties for specified war crimes, such as willful killing and torture, with no statute of limitations.

Statutes of Limitations in Personal Finance

Consumer debt

Once the limitation period on a consumer debt expires, the debt becomes time-barred. The creditor or collector can no longer win a lawsuit to collect it, which means it cannot obtain a court judgment to garnish wages or place a lien on assets. Federal debt collection rules (Regulation F under the Fair Debt Collection Practices Act) prohibit debt collectors from suing or threatening to sue on a time-barred debt.

A time-barred debt is not erased, though. The consumer still legally owes it, and collectors may still contact the consumer and ask for voluntary payment, within the rules on collection practices. In some states, making any payment on a time-barred debt, or acknowledging the debt in writing, can restart the limitation period and give the creditor a fresh right to sue.

The statute of limitations is also separate from credit reporting. Under the Fair Credit Reporting Act, most negative items, including delinquent accounts, can stay on a credit report for seven years from the original delinquency. That seven-year period runs on its own schedule. A debt can be time-barred but still appear on a credit report, or drop off the report while it is still within the limitation period and could be sued on. Restarting the legal clock with a payment does not restart the seven-year reporting period.

Taxes and the IRS

Federal tax law sets several separate windows:

• Assessment: the IRS generally has three years from the date a return is filed to assess additional tax. The period is longer in some cases, such as six years when a substantial amount of income is omitted, and there is no limit when no return is filed or a fraudulent return is filed.
• Collection: once tax is assessed, the IRS generally has 10 years to collect it.
• Refunds: a taxpayer generally must claim a refund or credit within three years of filing the return or two years of paying the tax, whichever is later.

After the relevant period ends, the IRS cannot assess or collect the additional amount, and the taxpayer cannot claim the refund.

Lawsuits against the government

When Congress creates a right to sue the federal government, it usually attaches its own filing deadline. In these cases, missing the deadline can remove the right to sue entirely, not just give the government a defense to raise.

Worked Example: A Time-Barred Credit Card Debt

Hypothetical example for illustration. Actual periods and restart rules depend on the state and the type of debt.

Assume a state sets a four-year statute of limitations on credit card debt, measured from the last payment, and treats any later payment as restarting the clock.

1. Dana makes her last credit card payment on March 1, 2019. The account is charged off and sold to a debt buyer.
2. The period ends four years later, on March 1, 2023.
3. In June 2023, a collector calls. No lawsuit was filed in time, so the debt is time-barred: the collector may ask for voluntary payment but cannot sue or threaten to sue.
4. If Dana sends a $50 “good faith” payment in July 2023, the clock restarts in this assumed state, and the collector has until July 2027 to sue for the remaining balance.
5. The negative credit reporting still runs seven years from the 2019 delinquency, so it would leave her report around 2026 regardless of the payment.

Why Statutes of Limitations Exist

The main justification is fairness to defendants. Over time, documents are lost, physical evidence degrades, and witnesses forget or die. A case brought long after the fact may be impossible to defend properly, and the risk of a wrong outcome rises.

Several related purposes follow from that:

• Legal certainty: people and businesses can eventually treat old disputes as closed, rather than facing open-ended exposure.
• Prompt action: deadlines push injured parties and prosecutors to act while evidence is fresh.
• Court efficiency: courts spend less time on stale claims that are hard to prove.

Drawbacks and Criticism

The most direct criticism is that a statute of limitations can protect wrongdoers. If a crime or wrongful act is not discovered, or a victim is not ready to come forward, until after the deadline, the responsible party may face no legal consequence at all.

Fixed periods can also be rigid. Discovery rules and tolling do not cover every situation, and a strict outer deadline can expire before a medical malpractice victim even understands the injury.

Deadlines can fall hardest on people with the fewest resources. Someone who does not know their rights, or who assumes they need money upfront to hire a lawyer, may let the period expire without realizing a claim existed.

Finally, variation between jurisdictions causes confusion: the same claim, such as an oral contract dispute, can carry very different deadlines from state to state, and a person dealing with an out-of-state party may not know which period applies.

How legislatures respond: the New York Child Victims Act

Criticism of this kind has led some states to lengthen or remove deadlines. New York’s Child Victims Act, enacted Feb. 14, 2019, lets survivors of child sexual abuse seek criminal charges until age 28, up from 23, and file civil suits until age 55. It also opened a one-time, one-year window for survivors of any age to file civil claims that had already expired, the most contested part of the bill.

Statute of Limitations vs. Related Concepts

Statute of repose: a statute of repose sets an absolute outer limit measured from a fixed event, such as the date of a medical procedure or the completion of a building, regardless of when the harm was discovered. A statute of limitations can be delayed by a discovery rule or tolling; a statute of repose generally cannot. Texas, for example, pairs its two-year limitation period for health care liability claims with a 10-year outer limit measured from the act or omission.

Double jeopardy: the statute of limitations controls when charges can first be filed. Double jeopardy is a constitutional protection against being tried again for the same offense after an acquittal or conviction. They are separate rules: a person can be protected by one, both or neither.

FAQs

The Bottom Line

Anyone facing a possible lawsuit, an old debt collector call or a tax question should check which deadline applies, since periods vary by state and type of claim. A case must actually be filed before the period ends, and letters or negotiations usually do not stop the clock. People with time-barred debt should know that a payment can restart the legal clock in some states, even though the debt itself is never erased.
