In most states, the statute of limitations for armed robbery runs between five and ten years from the date of the crime, but several states impose no time limit at all, and others remove the deadline whenever the offense is punishable by life in prison. Federal armed robbery charges generally carry a five-year filing window, with no limit if someone died during the robbery. The exact deadline turns on how your state classifies the offense within its felony tiers and whether any event has paused the clock.
How Long Prosecutors Have in Each State
State deadlines fall into three groups. At least five states impose no statute of limitations for any felony, so armed robbery charges can be filed decades after the fact. A larger group removes the time limit specifically for crimes punishable by life imprisonment, and armed robbery often qualifies because many states grade it as a first-degree felony with a potential life sentence. The remaining states set fixed deadlines, most commonly five to ten years from the date of the robbery.
Where your state lands depends on classification, not the name of the charge. A state that treats armed robbery as a first-degree felony punishable by life may have no filing deadline at all, while a neighboring state that caps the sentence at twenty years might impose a six- or ten-year limit. Two states can both call the crime “armed robbery” and still apply very different time limits because of how their felony structures are built.
When the Clock Starts
For armed robbery, the limitations period begins on the date the crime was committed. Unlike fraud or embezzlement, where a victim may not realize for months or years that something happened, armed robbery is immediately apparent. The victim knows what occurred and when. Courts rarely apply “discovery rule” exceptions that delay the start of the clock for offenses like these.
So if your state sets a seven-year window, prosecutors have exactly seven years from the day of the robbery to file charges, subject to the tolling rules below.
What Pauses the Clock
Tolling temporarily stops the limitations period from running, giving prosecutors extra time and preventing suspects from waiting out the deadline by making themselves unavailable. Three triggers come up most often in armed robbery cases:
- Fleeing the jurisdiction. If a suspect leaves the state or goes into hiding, the clock pauses until they return or are found. Federal law is blunter: no statute of limitations extends to any person fleeing from justice, so the clock stops entirely for a federal fugitive.1Office of the Law Revision Counsel. 18 USC 3290 – Fugitives From Justice
- Unknown identity. Many states pause the clock while law enforcement does not yet know who committed the crime. The period resumes once the suspect is identified.
- Incarceration for another crime. Some states toll the statute while the suspect is serving a prison sentence for an unrelated offense, since they cannot easily be brought to trial during that time.
This is where people miscount. Someone who assumes the time limit has passed because the robbery happened eight years ago may not realize that three years spent living in another state didn’t count. The actual elapsed time on the clock could be only five.
DNA Evidence Can Reopen the Window
A growing number of states have carved out DNA-based exceptions to their statutes of limitations. These laws let prosecutors bring charges after the normal deadline if DNA evidence identifies the suspect. Some states apply the exception broadly to violent felonies including robbery; others limit it to sexual offenses. A few permit prosecution at any time once a DNA match is established, regardless of how many years have passed.
For armed robbery suspects who were never identified through traditional investigation, a cold-case DNA hit can revive the legal threat decades later. Whether the exception reaches your case depends on state law, but the trend is toward broader coverage of violent crimes.
Federal Armed Robbery Deadlines
Armed robbery is overwhelmingly a state matter, but federal charges apply in two situations: when the target is a federally insured bank or credit union, and when the robbery affects interstate commerce.
Bank Robbery
The federal bank robbery statute covers anyone who takes money or property from a bank, credit union, or savings institution by force, intimidation, or extortion. With a dangerous weapon, the maximum penalty is twenty-five years. If someone is killed during the robbery, the offense becomes punishable by death or life imprisonment.2Office of the Law Revision Counsel. 18 USC 2113 – Bank Robbery and Incidental Crimes
Hobbs Act Robbery
The Hobbs Act makes it a federal crime to obstruct or affect interstate commerce through robbery or extortion. It reaches beyond banks to cover robberies of businesses, individuals, or operations connected to commerce crossing state lines. A conviction carries up to twenty years.3Office of the Law Revision Counsel. 18 USC 1951 – Interference With Commerce by Threats or Violence
The Federal Clock
The general federal statute of limitations is five years for any non-capital offense. An indictment must be found or charges formally filed within that window.4Office of the Law Revision Counsel. 18 U.S. Code 3282 – Offenses Not Capital That five-year period applies to most armed bank robberies and Hobbs Act cases. The critical exception: if the robbery results in a death, the offense becomes punishable by death or life imprisonment, and federal law provides that an indictment for any offense punishable by death may be brought “at any time without limitation.”5Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses
If the Deadline Has Passed
Once the statute of limitations runs out before charges are filed, the case is over. A defendant charged after the deadline can move to dismiss, and the court will grant the motion. At the federal level, once a case is dismissed because prosecutors failed to file within the required period, they cannot refile with a new indictment.6Congress.gov. Statute of Limitation in Federal Criminal Cases – An Overview The protection is permanent for that offense.
Two things to keep in mind. First, courts examine tolling periods, any time the suspect spent outside the jurisdiction, and whether the charges fall under a no-limit category before agreeing the deadline has passed. Counting calendar years from the date of the robbery is not enough. Second, the statute of limitations is an affirmative defense: the defendant has to raise it. Courts do not automatically check whether the filing deadline has run. If the defense is not asserted, the case proceeds regardless of timing. Anyone facing charges for an armed robbery that occurred years ago should work through the full limitations period, including every potential pause, before assuming the window has closed.
