About This Calculator
This calculator finds your exact filing deadline for a personal injury claim in Massachusetts. It applies Massachusetts's specific statute of limitations period, checks whether the discovery rule extends your deadline, accounts for tolling if the injured party was a minor, and flags any special notice requirements if your claim involves a government entity. Enter your incident date — or discovery date if the harm wasn't immediately apparent — and the calculator counts forward using Massachusetts's exact rule to show your filing deadline, the time remaining, and an urgency status. Results are based on verified state statute citations, not general estimates.

How Massachusetts's Personal Injury Deadline Works
Under Massachusetts Rev. Stat. § 71, Massachusetts provides 3 years to file a personal injury lawsuit. The clock typically begins when the injury was discovered — or when it reasonably should have been discovered — rather than on the date the harm occurred. This is known as the discovery rule. Massachusetts extends the filing window by up to 1 additional year under the discovery rule.
Massachusetts's personal injury statute of limitations is governed by the state's civil procedure and limitations statutes. Claims against state agencies, municipalities, or other government entities in Massachusetts may require filing a formal notice of claim before suit can be commenced — notice deadlines vary by entity type and are often shorter than the civil filing deadline. Under state law, the limitations period is tolled for minor claimants until they reach the age of majority at 18.
Special Circumstances
Government entity claims: If the defendant is a government entity, Massachusetts requires a formal administrative claim notice to be filed within 6 months of the incident before a lawsuit may be filed. Missing this notice deadline permanently bars the claim. After the claim is rejected, you have 12 months to file suit.
Minor claimants: If the injured person was a minor at the time of the incident, Massachusetts tolls the statute of limitations until they reach age 18.
What Happens If You Miss the Deadline
If a lawsuit is filed after the statute of limitations expires, the defendant can ask the court to dismiss the case as time-barred — and courts almost always grant this motion, regardless of how strong the underlying claim is. The right to sue is lost permanently; there is no general exception for not knowing the deadline existed. A small number of circumstances can pause or extend the clock, covered in the Special Circumstances section above if they apply to your claim type and state. If your deadline is approaching or may have already passed, contact a licensed attorney immediately — some exceptions are themselves time-sensitive.
Frequently Asked Questions
How does minor tolling affect personal injury deadlines in Massachusetts?
Massachusetts law tolls the personal injury statute of limitations for individuals under the age of 18. The clock does not begin ticking until the minor reaches adulthood. However, this tolling provision is explicitly removed for certain medical malpractice claims involving young children, which face strict time caps.
Is medical malpractice governed by the Massachusetts personal injury deadline?
Massachusetts handles medical malpractice under a separate statutory framework with its own distinct deadlines. Furthermore, the state enforces a strict seven-year statute of repose for medical negligence, acting as an absolute cutoff regardless of discovery. General tort deadlines do not apply to healthcare providers.
What is the time limit for wrongful death claims in Massachusetts?
If an injury proves fatal, the case must proceed under the Massachusetts wrongful death statute. The deadline for wrongful death typically runs from the date of death and is independent of the standard personal injury timeframe. The executor or administrator of the estate must initiate the action.
How does Massachusetts apply the discovery rule to personal injuries?
Massachusetts applies the discovery rule to inherently unknowable injuries. The statute of limitations is paused until the plaintiff learns, or reasonably should have learned, that they were harmed and that the defendant caused the harm. This is frequently used in cases of slow-developing diseases or latent product defects.
Are there special requirements to sue a government entity in Massachusetts?
Under the Massachusetts Tort Claims Act, you cannot sue a public employer without first presenting a formal administrative claim. This presentment must be made within two years of the date the cause of action accrued. The lawsuit itself is barred if this mandatory administrative step is missed.
