The difference between a misdemeanor and a felony is the single most important fact about a criminal charge, because it sets the ceiling on the punishment and the depth of the consequences that follow a conviction. A misdemeanor is a less serious crime, almost always punishable by no more than one year in a county or local jail. A felony is a serious crime, punishable by more than a year, typically in a state prison, and it carries a long tail of collateral consequences that a misdemeanor usually does not. The line is drawn by the maximum sentence the legislature attached to the offense, not by what the judge actually imposes.
This post explains where the line sits, how states grade offenses into classes and degrees, the practical difference between jail and prison, the collateral consequences that attach to each, the in-between offenses called wobblers, and why felonies are harder to clear from a record later.
What is the difference between a misdemeanor and a felony?
The dividing line is the authorized maximum term of confinement. The traditional common-law rule, carried into most modern statutes, treats any crime punishable by more than one year as a felony and any crime punishable by up to one year as a misdemeanor. The federal system codifies this directly: under 18 U.S.C. 3559, an offense with a maximum term of more than one year is a felony, and an offense capped at one year or less is a misdemeanor, with petty offenses graded below that.
A few points commonly trip people up. First, the classification follows the maximum the statute allows, not the sentence the defendant receives. A felony is still a felony even if the judge grants probation and the defendant never spends a day in prison. Second, where the time is served matters. Misdemeanor time is generally served in a county or city jail, while felony time is generally served in a state prison system. Third, many states recognize a third, lowest tier, often called an infraction or a violation, for conduct like most traffic offenses, which carries only a fine and no jail.
Below the felony line, states also separate the most minor crimes. A petty offense or a low-grade misdemeanor may be punishable by a small fine and a few days in jail, while a high-grade misdemeanor can approach the one-year ceiling.
How states grade crimes into classes and degrees
There is no single national grading scheme. Each state sorts its crimes, and the labels vary, but the logic is consistent: the more serious the crime, the higher the class or degree and the longer the authorized term.
Many states use lettered classes. New York, for example, grades felonies from Class A (the most serious, including the most serious homicides) down through Class E, and grades misdemeanors as Class A, Class B, or unclassified. Texas grades felonies as capital, first degree, second degree, third degree, and state jail felony, and grades misdemeanors as Class A, B, or C. Other states use numbered degrees, where first degree is the most serious. The federal system uses letter classes A through E for felonies and A through C for misdemeanors.
The class or degree controls the sentencing range. A Class A misdemeanor in one state might authorize up to one year in jail and a fine, while a Class C misdemeanor might authorize only a small fine. A first-degree felony might authorize decades in prison, while the lowest felony class might authorize a year and a day. Because the schemes differ, the same conduct can be graded differently depending on the state where it is charged, which is one reason state variation matters so much in criminal law.
Jail versus prison: why the place of confinement matters
People use the words jail and prison interchangeably in conversation, but they are different institutions with different consequences. Jail is a short-term, locally run facility, usually operated by a county or city, that holds people awaiting trial and people serving short misdemeanor sentences. Prison is a longer-term facility, run by a state department of corrections or the federal Bureau of Prisons, that holds people serving felony sentences of more than a year.
The distinction is not just geographic. A felony conviction and the prison term that can accompany it trigger consequences that a jail sentence often does not, from the loss of firearm rights to immigration exposure to barriers in licensing and employment. The sentence ceiling, in other words, is a proxy for how seriously the law treats the conduct and how heavily it will weigh on the rest of a person's life.
The collateral consequences of a felony
The sentence is only the part of a conviction you can see. The collateral consequences are the civil disabilities that attach by operation of law once a person is convicted, and they fall hardest on felonies. They are not imposed by the sentencing judge. They flow automatically from statutes and regulations spread across federal and state law.
Voting. Most states suspend the right to vote during a felony sentence, and the rules for restoration vary widely. Some states restore the vote automatically upon release, some upon completion of parole or probation, and a small number impose longer waiting periods or require additional steps. Misdemeanors generally do not affect voting rights.
Firearms. Federal law, at 18 U.S.C. 922(g), makes it a crime for a person convicted of a felony to possess a firearm. Many states layer their own firearm prohibitions on top, and some extend prohibitions to certain misdemeanors, most notably misdemeanor crimes of domestic violence, which trigger the same federal firearm ban.
Employment and licensing. A felony conviction can disqualify a person from many occupational licenses, from professional positions, and from jobs that require a clean background check. Many states regulate how far back and in what circumstances an employer may consider a conviction, so the practical effect varies by state and by industry.
Immigration. For a non-citizen, the immigration consequences of a conviction can dwarf the criminal sentence. Certain offenses are classified as aggravated felonies or crimes involving moral turpitude under federal immigration law, and a conviction can lead to deportation, denial of naturalization, or inadmissibility. The immigration label does not always track the state criminal label, so a crime a state calls a misdemeanor can still carry severe immigration consequences. A non-citizen facing any charge should consult a lawyer who handles both criminal and immigration law before entering any plea.
Other consequences can include ineligibility for some public benefits, restrictions on jury service, and barriers to housing. The combined weight of these consequences is why the felony line matters long after a sentence is served.
What is a wobbler?
A wobbler is an offense that the law allows to be charged or punished as either a felony or a misdemeanor. California is the best-known example, but several states have a version of the concept. For a wobbler, the prosecutor's charging decision and the judge's sentencing decision determine which side of the line the case lands on.
Wobblers matter because they create room to argue. A defense lawyer can push to keep a wobbler on the misdemeanor side, or to reduce a felony wobbler to a misdemeanor at sentencing or afterward. In California, for instance, Penal Code section 17(b) gives the court authority to reduce many wobblers from a felony to a misdemeanor in defined circumstances. The exact mechanism and the list of eligible offenses are state-specific.
Can a felony be reduced to a misdemeanor?
Sometimes, yes, but it depends entirely on the offense and the state. There are a few common paths.
The first is the wobbler reduction described above. If the underlying crime is a wobbler, a court may have statutory authority to reduce it to a misdemeanor, often after the defendant completes probation. The second is a negotiated plea, where the prosecution agrees to let the defendant plead to a misdemeanor rather than a felony, which is one of the most common ways charges get reduced before conviction. The third is a statutory reclassification, where a state changes the grading of an offense and provides a process to apply the new, lower classification to past convictions; California's reclassification of certain drug and theft offenses is a well-known example.
Crimes that are felonies by definition, such as the most serious violent offenses, generally cannot be reduced this way. And even where a reduction is available, it usually requires a petition, eligibility under the statute, and in many cases the completion of the sentence or probation first.
Why felonies are harder to clear from a record
Clearing a conviction, through expungement, sealing, or a set-aside depending on the state's terminology, is governed by state statute, and the rules almost always treat felonies more strictly than misdemeanors. Misdemeanors typically become eligible sooner, with shorter waiting periods after the case closes, and more misdemeanor offenses qualify. Felonies, where they are eligible at all, usually carry longer waiting periods, more exclusions, and more conditions.
Some categories of felony, particularly serious or violent offenses and certain sex offenses, are excluded from expungement entirely in many states. The relief available also varies in kind. Expungement may destroy or hide the record from public view, while sealing may restrict access without erasing it, and a set-aside may vacate the conviction while leaving a record that it once existed. Because eligibility, waiting periods, and the effect of the relief all turn on state law and on whether the conviction was a misdemeanor or a felony, the classification you carry out of a case shapes how, and whether, you can ever clear it.
