Selling stuff at school is not illegal by itself, but almost every school district bans unauthorized sales on campus, and what you’re selling determines whether you’re looking at a confiscated backpack of candy or actual criminal charges. A student selling friendship bracelets between classes is in a completely different legal position than one selling vape cartridges in the bathroom. The response depends on the item, your school’s code of conduct, and the laws of your state.
The Default School Rule
Most districts prohibit students from selling anything on campus without administrator approval. The rule sits in the student handbook or district code of conduct, and it applies whether you’re moving candy bars, custom T-shirts, or phone accessories. The usual exception is fundraising organized through an official student club or school-sponsored group, where products have been vetted and the money has a documented purpose.
Getting caught triggers the school’s disciplinary process, and the response scales with what you were selling and whether you’ve been warned before. A first offense involving harmless items typically means a conversation, confiscation, or detention. Repeat offenses or higher-value operations move up the ladder: in-school suspension, out-of-school suspension, or reassignment to an alternative program. Expulsion is rare for non-contraband sales but stays on the table for persistent violations. When a suspension runs more than a few days or expulsion is proposed, public schools generally have to offer a hearing where you can present your side and bring a parent or attorney.
None of that is criminal. It’s school discipline. The criminal question turns entirely on what’s changing hands.
When Selling Becomes a Crime
Three categories reliably turn a school policy matter into a law enforcement matter.
Drugs and Controlled Substances
Selling drugs at school carries some of the harshest penalties in criminal law. Federal law doubles the maximum punishment for distributing or possessing with intent to distribute a controlled substance within 1,000 feet of a school, and imposes a mandatory minimum sentence of at least one year in prison with no possibility of probation or parole for that minimum term.1Office of the Law Revision Counsel. 21 USC 860 – Distribution or Manufacturing in or Near Schools and Colleges The only exception is for offenses involving five grams or less of marijuana. Most states have parallel school-zone laws that stack additional penalties on top of the federal ones.
For students under 18, these cases usually begin in juvenile court, where outcomes range from probation and mandatory drug treatment to placement in a juvenile detention facility. Judges weigh the type and quantity of substance, prior offenses, and how the sale was conducted. Being a minor is not a shield: in many states, older teens charged with distributing drugs at school can be transferred to adult court.
Weapons
Federal law requires every state receiving federal education funding to have a law mandating at least a one-year expulsion for any student who brings a firearm to school or possesses one on school property.2Office of the Law Revision Counsel. 20 USC 7961 – Gun-Free Requirements A school’s chief administrator can modify the expulsion case by case, but the default is a full school year out. Selling a weapon on campus would trigger this provision and expose the student to state criminal weapons charges on top, which are uniformly severe when schools are involved.
Counterfeit and Stolen Goods
Selling fake brand-name goods, even to classmates, can trigger federal criminal liability. Trafficking in goods bearing counterfeit marks is a federal offense that applies regardless of the seller’s age or the scale of the operation.3Office of the Law Revision Counsel. 18 USC 2320 – Trafficking in Counterfeit Goods or Services Selling stolen property is a separate state-level crime and can be charged as a felony depending on the value of the goods. Both leave marks on your record that surface on background checks for college admissions, scholarships, and jobs.
Food Sales Have Extra Rules
Food is what most students actually try to sell, and it comes with a layer of federal regulation on top of the school’s own policy. Anything sold to students on campus during the school day at a school participating in the National School Lunch Program has to meet federal nutrition standards known as the Smart Snacks rules. These cover all “competitive foods,” meaning anything sold outside the official meal programs.
The limits are specific. Snack items cannot exceed 200 calories, 200 mg of sodium, or 35% of calories from total fat, and must contain zero grams of trans fat.4USDA Food and Nutrition Service. A Guide to Smart Snacks in School The food must also have a fruit, vegetable, dairy product, protein, or whole grain as its first ingredient. Fresh fruits, vegetables, and plain water are always compliant. Homemade cookies, regular soda, and standard candy bars almost certainly fail these standards.
Enforcement technically falls on the school, not the student, which is why schools shut down unauthorized food sales so aggressively: every unapproved snack sold on campus puts the school’s own compliance at risk. Some states also have cottage food laws governing home-baked goods, and many of those require basic permits or limit where the products can be sold.
Selling School-Branded Merchandise
Students making custom T-shirts, hoodies, or stickers sometimes put the school’s name, mascot, or logo on the product without thinking twice. Most school names and logos are trademarked, and selling products bearing those marks without a license is trademark infringement. The legal theories include likelihood of confusion (people think the school endorsed it), dilution, and tarnishment.
A school district is far more likely to confiscate your inventory and discipline you than to sue you. Colleges and universities are notably more aggressive about protecting their trademarks, though, and if your products feature a university logo, you could receive a cease-and-desist letter even as a high school student. If you want to sell school-branded merchandise, ask the administration about the licensing process before you print anything.
Taxes If You’re Actually Making Money
Profit from selling things at school is taxable income, and the IRS does not care that you’re a student. If your net earnings from self-employment hit $400 in a year, you owe self-employment tax (Social Security and Medicare) and must file Schedule SE with your federal return. This applies regardless of your age, even if you’re claimed as a dependent on a parent’s return.5Internal Revenue Service. Instructions for Schedule SE (Form 1040)
If you accept payments through Venmo, PayPal, or Cash App, the platform is required to report your transactions to the IRS on Form 1099-K once you exceed $20,000 in gross payments across more than 200 transactions in a calendar year.6Internal Revenue Service. Understanding Your Form 1099-K Most student sellers won’t hit that threshold, but the reporting rule doesn’t change your underlying liability. You owe tax on the profit whether or not anyone sends you a form.
Keeping records of what you spent on supplies and inventory matters. Your taxable profit is revenue minus legitimate expenses, and those deductions can keep you below the threshold.
If Someone Gets Hurt by What You Sold
If something you sell at school injures someone or damages their property, you can face a civil lawsuit. A student who sells homemade food that causes an allergic reaction, or an electronic device that malfunctions and starts a fire, can be held personally liable. For minors, that often means the parents end up paying.
One wrinkle may work in a student seller’s favor. The implied warranty of merchantability, a legal default that goods must be fit for their ordinary purpose, only applies to sellers who are “merchants” dealing in goods of that kind.7Legal Information Institute (LII) / Cornell Law School. UCC 2-314 – Implied Warranty: Merchantability; Usage of Trade A student running a one-off sale probably doesn’t qualify. Ordinary negligence claims don’t need merchant status, though. If you sold something you knew or should have known was dangerous, the warranty question doesn’t help you.
Doing It the Legal Way
If you genuinely want to sell something at school, the path that avoids every problem above runs through the administration. Start by talking to a teacher, club advisor, or assistant principal about what you want to sell and why. Most schools have a formal or informal approval process for fundraisers, and attaching your idea to an existing student organization dramatically improves your odds.
Schools that approve student sales typically want a written proposal covering the product, price, where and when the sales will happen, and what the proceeds will fund. Food sales draw the tightest scrutiny because of the federal nutrition standards, so non-food items are an easier sell. If your school says no, that ends it on campus, but nothing stops you from selling online, at community events, or through channels off school property where the school’s authority doesn’t reach.
