Felony assault in Michigan is not a single offense but a group of separate crimes defined by the weapon used, the harm caused, the defendant’s intent, and who the victim was. Penalties run from two years in prison up to life, and most convictions carry mandatory restitution, a permanent firearms ban under federal law, and possible immigration consequences on top of the sentence itself.
What Turns an Assault Into a Felony
Simple assault and battery is a misdemeanor punishable by up to 93 days in jail and a $500 fine.1Michigan Legislature. Michigan Code MCL 750.81 – Assault and Battery An assault becomes a felony when a dangerous weapon is involved, when the defendant intended serious harm or death, when strangulation or suffocation occurred, or when the victim was performing public duties.
One statute causes constant confusion. MCL 750.81a, often called “aggravated assault,” is a misdemeanor for first-time offenders — assault without a weapon that causes serious injury, punishable by up to a year in jail and a $1,000 fine. It only becomes a felony when the defendant has prior domestic violence convictions, at which point the penalty rises to five years in prison and a $5,000 fine.2Michigan Legislature. Michigan Code 750.81a – Assault; Infliction of Serious or Aggravated Injury The real felony assault charges sit in separate statutes.
The Felony Assault Charges
Felonious Assault (MCL 750.82)
Felonious assault means assaulting someone with a dangerous weapon — a gun, knife, iron bar, club, brass knuckles, or similar object — without intending murder or great bodily harm. The weapon is the key, not the injury. Pointing a loaded gun at someone qualifies even if no shot is fired and no one is hurt. The standard penalty is up to four years in prison and a $2,000 fine.3Michigan Legislature. Michigan Code MCL 750.82 – Felonious Assault
Two circumstances raise the stakes. When the victim is an on-duty health professional or medical volunteer, the fine doubles to $4,000. When the offense occurs in a weapon-free school zone, the fine rises to $6,000 with up to 150 hours of community service.3Michigan Legislature. Michigan Code MCL 750.82 – Felonious Assault
Assault With Intent to Do Great Bodily Harm (MCL 750.84)
This charge covers assaults where the defendant intended serious physical harm short of death. No weapon is required; bare-handed attacks qualify if intent can be proved. The same statute also covers assault by strangulation or suffocation, defined as intentionally blocking someone’s airway or blood circulation by applying pressure to the throat, neck, nose, or mouth. Both carry up to 10 years in prison and a $5,000 fine.4Michigan Legislature. Michigan Code 750.84 – Assault With Intent to Do Great Bodily Harm Less Than Murder
The strangulation provision matters because it does not require proof that the defendant intended great bodily harm. The act itself is enough, and the 10-year maximum applies even when no lasting injury results.
Assault With Intent to Murder (MCL 750.83)
The most serious assault charge in Michigan. It applies when someone attacks another person with the specific intent to kill, and it carries imprisonment for life or any term of years.5Michigan Legislature. Michigan Code 750.83 – Assault With Intent to Commit Murder Prosecutors must prove actual intent to kill, not merely to injure.
Assault on a Public Servant (MCL 750.81d)
Michigan imposes separate felony penalties for assaulting anyone performing official duties, including police officers, firefighters, paramedics, conservation officers, and court employees. The penalties are tiered by harm:
- No injury or minor contact: up to 2 years in prison and a $2,000 fine.
- Bodily injury requiring medical attention: up to 4 years in prison and a $5,000 fine.
- Serious impairment of a body function: up to 15 years in prison and a $10,000 fine.
- Death of the victim: up to 20 years in prison and a $20,000 fine.6Michigan Legislature. Michigan Code 750.81d – Assaulting, Battering, Resisting, Obstructing Person Performing Duty
“Obstruct” includes threatening physical force and knowingly failing to comply with a lawful command. A sentence under this section can run consecutively with any other sentence from the same incident, so the time stacks rather than running at the same time.6Michigan Legislature. Michigan Code 750.81d – Assaulting, Battering, Resisting, Obstructing Person Performing Duty
Sentence Add-Ons the Charge Doesn’t Show
Firearm Enhancement
Carrying or possessing a firearm during any felony triggers a mandatory consecutive prison term under MCL 750.227b. A first offense adds two years. A second adds five. A third or later adds 10. The enhancement is served before the sentence for the underlying felony begins, cannot be suspended, and the defendant is ineligible for parole or probation during that mandatory period.7Michigan Legislature. Michigan Code 750.227b – Carrying or Possessing Firearm When Committing or Attempting Felony A felonious assault committed with a gun therefore carries at least two additional years on top of whatever the judge imposes for the assault itself.
Habitual Offender Enhancement
Prior felony convictions — from Michigan or another state — raise the ceiling on a new sentence:
- Second felony: maximum can rise to 1.5 times the longest term allowed for a first conviction.8Michigan Legislature. Michigan Code 769.10 – Punishment for Subsequent Felony
- Third felony: maximum can rise to twice the longest first-conviction term.9Michigan Courts. Maximum Sentences for Habitual Offenders
- Fourth or later felony: if the current offense carries a first-conviction maximum of five years or more, the court can impose life; if less than five years, the maximum is capped at 15 years.10Michigan Legislature. Michigan Code MCL 769.12 – Habitual Offender Fourth Felony
Concretely: a standard felonious assault caps at four years. With one prior felony, six. With two, eight. With three or more, potentially 15. When the underlying charge already carries five or more years, such as assault with intent to do great bodily harm, a fourth-offense enhancement puts life imprisonment on the table.10Michigan Legislature. Michigan Code MCL 769.12 – Habitual Offender Fourth Felony
Defenses
Self-Defense
Michigan’s Self-Defense Act eliminates any duty to retreat.11Michigan Legislature. Michigan Code MCL 780.971 – Self-Defense Act Under MCL 780.972, a person who is not committing a crime may use deadly force anywhere they have a legal right to be if they honestly and reasonably believe it is necessary to prevent imminent death, great bodily harm, or sexual assault. The same standard applies to non-deadly force against any imminent unlawful use of force.12Justia Law. Michigan Code 780.972 – Use of Deadly Force by Individual Not Engaged in Commission of Crime
Two requirements matter. The belief must be both honest and reasonable — feeling threatened is not enough if a reasonable person in the same situation would not have. And the person claiming self-defense cannot have been committing a crime at the time.
Defense of Others
The same statute extends the defense to force used to protect a third party under the identical standard: honest and reasonable belief that the other person faces imminent death, great bodily harm, or sexual assault.12Justia Law. Michigan Code 780.972 – Use of Deadly Force by Individual Not Engaged in Commission of Crime Disproportionate force or a perceived threat that was never real will defeat it.
Lack of Intent
Several felony assault charges require specific intent. Assault with intent to do great bodily harm requires proof the defendant meant to cause serious injury, not just that serious injury happened. Assault with intent to murder requires proof of actual intent to kill. Where the prosecution cannot establish that mental state, the charge may be reduced to a lesser offense.
Constitutional Violations
Statements taken during a custodial interrogation without Miranda warnings are inadmissible. Physical evidence from an unlawful search or seizure can be suppressed. These challenges don’t establish innocence, but they can gut the prosecution’s case.
Restitution
Every felony assault sentence includes mandatory restitution to the victim. Under MCL 780.766, the defendant must cover the full financial loss caused by the crime: medical costs already paid and reasonably expected in the future, physical and occupational therapy, and lost income. For property, the defendant must return it or pay its fair market or replacement value.13Michigan Legislature. Michigan Code 780.766 – Victim Defined; Restitution; Order
Restitution applies even when the case ends through a delayed sentence, deferred judgment of guilt, or youthful trainee status.13Michigan Legislature. Michigan Code 780.766 – Victim Defined; Restitution; Order Victims may also file a separate civil lawsuit for damages restitution does not cover, including pain and suffering. The criminal restitution order and any civil judgment are independent.
What a Conviction Costs Beyond Prison
Federal law permanently bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.14Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Every Michigan felony assault charge meets that threshold. The ban applies whether or not a gun was involved in the underlying offense, and violating it is itself a federal felony.
If you are not a U.S. citizen, a felony assault conviction can trigger removal proceedings. Federal immigration law treats certain assault offenses as “aggravated felonies” for deportation purposes, and the definition is broader than the ordinary meaning of those words — it can capture offenses that are neither aggravated nor felonies in the usual sense. A conviction classified as an aggravated felony generally bars relief from deportation, and definitional changes apply retroactively to prior convictions. Consult an immigration attorney before entering any plea.
A felony assault conviction also affects employment, professional licensing, housing applications, and voting rights during incarceration. Michigan restores voting rights on release from prison, but the conviction stays on the record indefinitely unless expungement is available, and violent felonies face significant limits on eligibility.
