You can report an assault to the police at any time, no matter how long ago it happened, because there is no deadline on filing a police report. How long you have to report an assault matters most for what comes after the report: criminal prosecution runs on a clock called the statute of limitations, and depending on the offense and the state, that clock can be as short as one year or have no expiration at all.
The practical answer is that reporting sooner almost always helps. Evidence degrades, memories fade, and witnesses become harder to find. But if time has already passed, that does not automatically close the door.
How Long Prosecutors Have to File Charges
Statutes of limitations exist to keep prosecutions grounded in reliable evidence and to prevent people from living under the indefinite threat of charges.1FBI Law Enforcement Bulletin. Statutes of Limitation in Sexual Assault Cases The window depends on how the offense is classified and where it occurred.
Misdemeanor Assault
Simple assault, meaning a threat of violence or an attack causing minor injury, is usually charged as a misdemeanor. Most states give prosecutors one to three years from the date of the incident to bring charges. Once that period runs out, prosecution is generally off the table even if the evidence is strong.
Felony Assault
Assaults involving a weapon or serious injury typically rise to felony charges, and states allow anywhere from three to ten years to prosecute. Some states set even longer periods for assaults that cause permanent disfigurement or life-threatening harm.
Sexual Assault
Sexual assault is the area where the law has shifted most. At least 14 states have eliminated the criminal statute of limitations entirely for certain sex crimes, meaning charges can be filed decades after the offense.1FBI Law Enforcement Bulletin. Statutes of Limitation in Sexual Assault Cases Even in states that keep a deadline, it is often much longer than for other felonies, and legislatures have been extending these windows in recent years. If you experienced a sexual assault years ago and assumed it was too late, it may not be.
Federal Offenses
Assaults on federal property, in federal prisons, or against federal officers follow separate timelines. The general federal statute of limitations is five years for non-capital offenses.2Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Offenses punishable by death have no time limit at all.3Office of the Law Revision Counsel. 18 US Code 3281 – Capital Offenses Federal prosecution of sex crimes against minors also has no limitations period, which means a federal case may still be viable when a state case is time-barred.1FBI Law Enforcement Bulletin. Statutes of Limitation in Sexual Assault Cases
When the Clock Pauses
The limitations clock does not always run continuously. Certain circumstances pause it, a concept the law calls tolling.1FBI Law Enforcement Bulletin. Statutes of Limitation in Sexual Assault Cases
The Victim Was a Minor
When the victim is under 18 at the time of the assault, most states do not start the limitations clock until the victim turns 18. Some states go further for childhood sexual abuse, giving survivors until their 40s or 50s to take legal action.1FBI Law Enforcement Bulletin. Statutes of Limitation in Sexual Assault Cases
The Injury Was Discovered Later
Sometimes a victim does not immediately realize they were harmed, or the extent of an injury only becomes apparent later. Under the discovery rule, the clock starts when the victim discovers, or reasonably should have discovered, the injury. An internal injury diagnosed months later, for example, can reset the starting date to the day of diagnosis.
The Accused Fled or Went Into Hiding
If the person who committed the assault leaves the state or hides, the clock typically stops during that period. Under federal law, the statute of limitations is tolled during any period of fugitivity, and the accused does not even need to physically leave the jurisdiction. Concealment is enough.4United States Department of Justice Archives. Criminal Resource Manual 657 – Tolling of Statute of Limitations Most states have similar provisions.
Active-Duty Military Service
The Servicemembers Civil Relief Act prevents a servicemember’s period of military service from counting toward any statute of limitations, whether the servicemember is bringing a claim or defending against one.5Office of the Law Revision Counsel. 50 US Code 3936 – Statute of Limitations This applies in state and federal proceedings, but not to federal tax matters.
Civil Lawsuits Run on a Separate Clock
Criminal prosecution and civil lawsuits operate on completely separate timelines. Even if the criminal window has closed, you may still be able to sue the person who assaulted you for monetary damages. The reverse is also true: a criminal conviction does not automatically compensate the victim, so a civil suit can be worth pursuing regardless.
Civil deadlines for assault and battery claims vary widely. Some states give as little as one year from the date of the assault; others allow up to six. Many states set the personal injury deadline at two or three years. Because the civil window can be shorter than the criminal one, consulting a personal injury attorney sooner rather than later matters, even if a criminal case is still pending.
A successful civil claim can recover compensation for medical expenses, lost income, therapy and counseling costs, and pain and suffering. In cases involving especially egregious conduct, courts may also award punitive damages.
How to File the Report
If an assault is happening right now or you are in immediate danger, call 911.6911.gov. Calling 911 For an assault that already occurred and where there is no present danger, you have a few options: call the non-emergency line for your local police department, go to a precinct in person, or in some jurisdictions, submit an online report.7USAGov. Report a Crime Filing in person has the advantage of a face-to-face conversation where you can walk the officer through the details.
Organize what you can before you arrive:
- The date, time, and specific location of the assault
- A chronological description of what happened
- The name of the person who committed the assault, or a detailed physical description
- Names and contact information for any witnesses
- A description of your injuries and any medical treatment you received
- Any physical evidence you preserved, including photographs or saved clothing
After filing, you should receive a police report number. Keep it. You will need it to follow up on the investigation, apply for victim compensation, or pursue a civil case.
One boundary worth knowing: certain professionals are legally required to report suspected abuse when they encounter it. Every state has mandatory reporting laws for child abuse, and the list of mandated reporters typically includes healthcare professionals, teachers, social workers, childcare providers, and law enforcement officers.8Child Welfare Information Gateway. Mandated Reporting Some states extend the obligation to all adults.
Preserve Evidence While You Can
Evidence degrades quickly. What you do in the hours and days after an assault can shape both a criminal prosecution and any civil claim.
- Seek medical attention even if injuries seem minor. A medical record created close to the event is powerful evidence. For sexual assault, a forensic medical exam (sometimes called a SAFE exam) can collect DNA and document injuries. Older guidance suggested a 72-hour limit, but current Department of Justice guidance recommends offering the exam at any time after the assault; evidence has been recovered well beyond that window.
- If you can, avoid washing or changing clothes before a medical exam. If you already have, go to the hospital anyway. Evidence may still exist.
- Photograph visible injuries with your phone, and take new photos over the following days as bruises develop and change.
- If you change clothes before an exam, place each item in a separate paper bag, not plastic, which traps moisture and degrades biological evidence.
- Write down what happened while your memory is fresh. Include date, time, location, what was said, the order of events, and any identifying details.
- Save text messages, voicemails, emails, and social media messages related to the assault. Screenshot anything that could be deleted.
If you are uncertain whether the window for prosecution or a civil suit has closed in your state, a local prosecutor’s office or a personal injury attorney can tell you where your case actually stands. The deadline that applies to you depends on facts specific to the offense, and the tolling rules described above may give you more time than you think.
