No, not to start. Under SBA guidance, if you sell on your own under your legal name, you're automatically a sole proprietor and don't need to register anywhere, and Stripe lets you sell without a separate business entity. What you do need to handle is taxes: the IRS expects you to report the income, and self-employment tax applies once net earnings reach $400. An LLC becomes worth it when real liability risk shows up.
Do I need an LLC to sell an app I built as a student?
You built something with AI over a few weekends. A few people use it, and one of them asks if they can pay for the pro version. Then a friend says you should "form an LLC first," and suddenly a $5 sale feels like it needs a lawyer.
It usually doesn't. We read public guidance from four organizations: the US Small Business Administration's guides to choosing a business structure and registering a business, the IRS pages on sole proprietorships, self-employment tax and Form 1099-K, Stripe's help center, and the government's Study in the States site for international students. None of them is written for students. Put together, they still answer the question. This isn't legal or tax advice, and state rules differ.
What do the sources agree on?
You're already a business the moment you sell. The SBA says you're automatically a sole proprietorship if you do business activities without registering as anything else. The IRS definition is just as plain: a sole proprietor is someone who owns an unincorporated business by themselves. No form creates this status. Charging for your app does.
Selling under your own name needs no registration. The SBA's registration guide says that if you do business as yourself using your legal name, you won't need to register anywhere. The catch is a brand name. If your app is sold under a name that isn't yours, most states require a "doing business as" (DBA) filing, and the SBA notes that a DBA alone gives you no legal protection.
Payment tools don't require a company. Stripe's help article on selling without a separate business entity says you can use it to sell a product without setting one up, and lists sole proprietorship as a signup option for people who operate alone.
Taxes apply either way. This is the part people skip. The IRS says you must report income from selling goods or services whether or not you receive a Form 1099-K. The 1099-K page gives the platform reporting threshold as over $20,000 in more than 200 transactions, but that's only about when a platform sends the form, not about whether you owe tax. Separately, you owe self-employment tax and file Schedule SE once your net earnings from self-employment reach $400. The rate is 15.3%, covering Social Security and Medicare. Sole proprietors report profit or loss on Schedule C with their Form 1040.
Where do they disagree, or stay silent?
When an LLC is worth it. The sources describe the trade-off but give no dollar line. The SBA says a sole proprietor can be held personally liable for the business's debts and obligations, and that LLCs protect you from personal liability "in most instances." It also says an LLC usually has to register with each state where it does business. Nobody says "form one at $1,000 a month." That's a judgment about risk, not revenue.
State rules. The SBA repeats that ownership rules, liability, taxes and filing requirements vary by state. A national source can't tell you your state's fees or annual filings. Your state's business filing office can.
International students. Only one source addresses them, and it changes the answer. The government's Study in the States page on entrepreneurship says starting your own business counts as work, so an F-1 student must qualify for and apply for practical training (OPT), and the business must relate to their program of study. For F-1 students, the first question isn't sole proprietorship or LLC. It's whether you're authorized to do this at all.
Students specifically. None of the sources mention dorm projects, class projects or student status. They also say nothing about your school's own rules on side businesses or on work built with school resources. If your app came out of a class, a lab or a campus job, ask before you sell it.
A decision rule you can use this week
| Your situation | What to do |
|---|---|
| Free tool, no money changing hands | Nothing to register. Keep building. |
| First paid users, selling under your own name | You're a sole proprietor. Sign up for payments as a sole proprietorship, keep records, report the income. |
| Selling under a brand name | Check whether your state or county requires a DBA filing. |
| Real liability risk: contracts with businesses, handling sensitive data, a co-founder, or meaningful money | Look at an LLC with your state's filing office, and consider a tax professional. |
| F-1 or other visa | Stop and talk to your international student office before taking any payment. |
And a short checklist for the first dollar:
- Decide whose name it's under. Your legal name means no registration. A brand name may mean a DBA.
- Open a separate account or at least a separate ledger. Even a spreadsheet tab with every payment, refund and expense will make tax time easy.
- Write down your costs. Keep receipts for hosting, domain, API and AI tool bills, and ask a tax professional which of them you can deduct.
- Assume you'll report it. No 1099-K doesn't mean no tax. Plan for self-employment tax if net earnings pass $400.
- Check your school. If the code, data or idea came from a class or a lab, ask the instructor or the relevant office before you sell.
- Revisit at the next step up. A co-founder, a business customer or sensitive user data are the moments to reconsider an LLC, not the first $5.
Why "one-person company" doesn't have to mean a legal company
The phrase sounds like paperwork, but for most students it describes a way of working: one person, using AI tools, takes a product from idea to real users. The legal structure can come later, and for many small products it never needs to change from a sole proprietorship.
STARC's one-person company cohort uses the phrase in that sense. It's eight weeks of building and shipping a small product with AI and finding real users. In week 6, the deliverable is to measure whether users come back, or to try charging, even $1. Charging a dollar is a test of whether the product is worth something to someone. It's a good moment to read the checklist above, and to ask a tax professional if your situation is more complicated. How the cohort works is on the How it works page, and common questions are in the FAQ.
The short version
You don't need an LLC to sell your first copy. Selling alone under your own name already makes you a sole proprietor, and payment platforms let you sign up as one. What you can't skip is the tax side: track every dollar and report it. Form an LLC when liability becomes real, check your state's rules when you do, and if you're on a student visa, get authorization before you sell anything.
Related questions
Can I take payments on Stripe without forming a company?
Yes. Stripe's help center says you can sell a product without a separate business entity and sign up as a sole proprietorship. You give your own details instead of a company's.
I only made a few hundred dollars. Do I have to report it?
Yes. The IRS says you must report income whether or not a payment platform sends you a Form 1099-K. Self-employment tax and Schedule SE kick in once net earnings from self-employment reach $400.
I'm an international student on an F-1 visa. Can I charge for my app?
Be careful. The government's Study in the States site says starting your own business counts as work, so F-1 students need practical training authorization (OPT) related to their field of study. Talk to your school's international student office before you take any payment.
Does an LLC protect me from everything?
No. The SBA says LLCs protect you from personal liability "in most instances," not all. It also says rules for each structure vary by state, so check your state's business filing office.
