Can you sue the government in small claims court? Start with the defendant
One rule sits underneath everything here, and it has an old name: sovereign immunity. You cannot sue a government unless that government has agreed to be sued. The agreement is called a waiver, and each level of government waived a different slice.
So the first question is never "can I sue?" It is "who, exactly, am I suing?" A federal agency, a state department, and your city each play by different rules. Get the defendant wrong and you lose months re-filing, because "the city" might legally be a county agency, a transit authority, or a state department, each with its own immunity rules and its own office where claims must be filed.
It is also your job, not the court's, to show that your case is one the law allows. When you cannot make that showing, the court dismisses the lawsuit at the government's request. Immunity is not a defense the judge discovers for you. It is a wall you have to prove has a door in it.
The federal government is a hard no in small claims court
You cannot sue a federal agency in small claims court, full stop. Congress waived federal immunity for certain tort claims in the Federal Tort Claims Act, but the route runs through an administrative claim filed with the agency first, usually on Standard Form 95. If the agency denies it or sits on it for six months, your next step is U.S. District Court. Small claims never enters the picture.
And some claims do not get through at all. The famous one is lost mail. Congress wrote an explicit exception, 28 U.S.C. 2680(b), for claims arising from the loss or miscarriage of postal matter. The post office losing your package is immune from suit, which is why every "can I sue USPS in small claims court" question ends the same way. The remedy is the postal insurance and indemnity claim process, not a judge.
States and cities can be sued, but the paperwork trap comes first
Every state has partially waived its own immunity in a law usually called a tort claims act. The typical waivers cover things like negligent operation of a government motor vehicle, dangerous conditions on government-owned property, and medical malpractice at public facilities. A city garbage truck rear-ending your car is one of the stronger small-claims fact patterns out there, because that waiver exists in many states.
Local governments, counties, townships, cities, get a related but separate protection called governmental immunity, and state law decides how far it reaches. In some states, a local government waives part of its immunity simply by buying liability insurance. The practical effect: whether you can sue your city depends on your state's statute, not on your sense of fairness.
One thing I have not seen any single guide settle: whether a particular city's insurance waiver covers your specific claim type is often genuinely unclear until a clerk or a court says so. The statutes are written for lawyers, and the line between a "governmental" function and a "proprietary" one, like a city-run parking garage competing with private lots, is argued case by case. If your claim sits on that line, that is the question to research before you spend a filing fee.
Frequently asked questions
Can I sue the post office in small claims court for a lost package?
No. The Federal Tort Claims Act excludes claims arising from the loss or miscarriage of postal matter, so the post office is immune for lost packages. Your remedy is the postal insurance and indemnity claim process, not a lawsuit.
Can I sue my city in small claims court over a pothole?
Sometimes. Many states waive immunity for dangerous conditions on government property, which is where pothole and road-hazard claims land. But almost everywhere you must first file a notice of claim with the city on a short deadline, commonly 60 to 120 days after the incident.
What is a notice of claim and how fast do I have to file it?
A notice of claim is a short written statement of what happened, where, and what you are owed, filed with the government office before you can sue. Deadlines are commonly 60 to 120 days from the incident, and missing the window usually kills the case before it starts.
Can I sue over a denied benefit or a tax dispute in small claims?
No. Benefit denials and tax disputes have their own administrative appeal processes and hearing officers. Small claims court has no jurisdiction over them.
Do I need a lawyer to sue a city or state agency?
Small claims court is designed for self-representation, but immunity arguments are where government cases die on paper. At minimum, read your state's tort claims act and the local notice-of-claim rules before filing, and consider a consultation if immunity might apply.
Check the limit, then check the notice deadline
First, confirm your claim fits the small claims court limit in your state. Then, today, look up your city or county's notice-of-claim deadline, because that window is measured in weeks and it started the day the incident happened.
