Forming an LLC does not lower a student founder's tax bill by a dollar. The IRS treats a limited liability company with one owner as a "disregarded entity" for income tax purposes, which means the business is not counted as separate from the person who owns it, and the profit lands on Schedule C of your personal Form 1040 exactly as it would if you had never filed anything with your state. That single fact rules out the most common reason students say they want an LLC. The real reasons to file are narrower, and so are the reasons to wait.
An LLC changes your legal exposure, not your tax bill
The IRS page on single-member LLCs, last updated July 27, 2026, says the owner of a disregarded entity reports the business on Schedule C, Schedule E or Schedule F of the personal return and is "subject to the tax on net earnings from self employment in the same manner as a sole proprietorship." The IRS puts that self-employment tax rate at 15.3%, and for 2026 the first $184,500 of combined wages, tips and net earnings is subject to the Social Security part of it. None of those numbers move because you filed articles of organization.
There is one split worth knowing: an LLC that is disregarded for income tax "is treated as a separate entity for purposes of employment tax and certain excise taxes," so once you put someone on payroll the LLC itself becomes the employer in the IRS's eyes. An LLC can also elect to be taxed as a corporation, but that is a separate election that brings payroll filings and the cost of running them.
On the employer identification number, the IRS is blunt: a single-member LLC that is a disregarded entity, has no employees and owes no excise tax does not need an EIN. Most students still want one, because it is free from the IRS online and because "if you don't need an EIN for federal tax purposes, you can still request one for banking or state tax purposes." An EIN also lets you fill in a client's W-9 without handing a stranger your Social Security number.
The filing fee is small, the annual fee is the one to plan for
The SBA's register your business guide says that "in most cases, the total cost to register your business will be less than $300, but fees vary depending on your state and business structure." It also notes that an LLC needs a registered agent in the state before you file, meaning a person or service with a street address there who accepts legal papers for you. If you live at a dorm address that changes every August, that is a recurring subscription cost rather than a one-time one.
The cost that catches people is the yearly one. Delaware, for example, tells owners that LLCs formed there do not file an annual report but "are required to pay an annual tax of $300.00," due no later than June 1 each year, according to the Division of Corporations. Other states charge an annual or biennial report fee instead, and a few charge a flat tax regardless of whether the business earned anything. Look up your own state's fee before filing, not after, and add it to the price of the decision for every year you plan to keep the entity alive.
Register in the state where the work actually happens. The SBA lists the triggers for being considered active in a state: a physical presence there, frequent in-person meetings with clients there, a significant portion of revenue from there, or employees working there. Businesses that qualify in a second state "typically need to pay taxes and annual report fees in both their state of formation and states where they're foreign qualified." For a student who mows lawns or shoots video around campus, the answer is almost always the state where the campus is, and filing in Delaware or Wyoming because a video recommended it just adds a second set of fees.
Example: suppose your state charges $120 to file and $75 for an annual report, and a registered agent service costs $100 a year. The first year runs $295 and each year after that runs $175. If the business clears $2,000 of profit in a year, the entity is eating roughly 9% of it, which is fine if it is buying you something and wasteful if it is not.
The liability shield is real but conditional
The SBA's business structure guide says LLCs "protect you from personal liability in most instances," and that phrase carries the weight. Courts can set the protection aside, a doctrine Cornell's Legal Information Institute describes as piercing the corporate veil: holding owners personally liable for the company's debts or actions. The factors it lists include intermingling personal and corporate assets and undercapitalization at the time of formation, though it also notes a strong presumption against piercing.
In practice that means an LLC you treat as a second wallet protects very little. Open a separate checking account, run every client payment and every business expense through it, pay yourself by transfer rather than by swiping the business card at the dining hall, and sign contracts in the company's name.
The shield also does not pay claims. The SBA's business insurance guide describes general liability coverage as protection "against financial loss as the result of bodily injury, property damage, medical expenses, libel, slander, defending lawsuits, and settlement bonds or judgments," and professional liability coverage as protection "against financial loss as a result of malpractice, errors, and negligence." If your work puts you on ladders, in client homes, around other people's vehicles or inside their data, a policy is the thing that writes the check. An LLC only decides whose assets are on the hook after that.
One federal filing that older guides still tell you to do is gone
Guides written in 2024 and 2025 told every new LLC owner to file a beneficial ownership information report with FinCEN. That requirement no longer applies to companies formed in the United States. FinCEN announced on August 11, 2026 a final rule that permanently removes the requirement for U.S. companies and U.S. persons to report beneficial ownership information under the Corporate Transparency Act, and said it would delete information already reported by U.S. persons who are now exempt. FinCEN's reporting page now states that U.S. companies are exempt and no longer required to file, while foreign entities that are reporting companies still report beneficial ownership information for foreign individuals. If a formation service tries to sell you a BOI filing package, that is a charge for nothing.
A short test for deciding this semester
The SBA says a sole proprietorship "can be a good choice for low-risk businesses and owners who want to test their business idea before forming a more formal business." Tutoring, freelance writing, design work and social media management for a handful of clients usually sit in that category. File the LLC when at least one of these is true:
- A client or campus department requires an entity and a certificate of insurance before it will sign.
- You are hiring anyone, including a classmate you pay per job.
- You have a co-founder, in which case the operating agreement that comes with the LLC is what records who owns what.
- Your work happens on other people's property or involves equipment that can damage something.
- You are signing a lease, financing equipment, or taking on inventory you have to pay for before you sell it.
If none of those apply yet, the useful work is the same with or without an entity: a separate bank account, a free EIN from the IRS, a written agreement that says what you deliver and when you get paid, and a quote for liability coverage so you know the number. The SBA's network of partners, including SCORE mentors and Small Business Development Centers, offers "free or low-cost counseling and training in your area," and a local counselor can tell you what your state and city require on top of the state filing.
Two limits on all of this. Business licenses, local permits and sales tax registration are separate from forming an entity, and a state filing does not satisfy them. And anything involving co-owners, outside money or a product that could injure someone is worth an hour with a lawyer in your state, because LLC rules are written state by state and the general picture above is where that conversation starts, not where it ends.
