There is no minimum age to own a company in the United States. A child of any age can hold stock in a corporation or membership interests in an LLC, because ownership is a property right and no federal or state law bars minors from holding property. The complications start when someone under 18 tries to do the things a business owner normally does: sign contracts, open a bank account, file formation papers, or serve as a manager. Those actions require legal capacity that minors generally lack until they turn 18.
Owning a Company Is Not the Same as Running One
Equity in a business is passive property. A ten-year-old can be the sole owner of an LLC and receive 100% of its profits without doing anything to maintain that ownership. Families use this regularly, transferring shares to children so the assets appreciate outside the parents’ taxable estate.
Operating the company is a different matter. The same ten-year-old almost certainly cannot sign the lease for the office, negotiate with vendors, or open the business bank account. Those tasks need someone with full legal capacity. The result is the arrangement you find in most minor-owned businesses: the young person holds the economic interest while an adult handles the legal machinery.
When a minor receives business interests as a gift or inheritance, the shares are commonly held in a custodial account under the Uniform Transfers to Minors Act. Every state has adopted a version of this law. An adult custodian, usually a parent, manages the property on the child’s behalf until the child reaches the age set by state law, typically 18 or 21. The custodian can vote shares and reinvest distributions but must act in the minor’s best interest, and the transfer is irrevocable. Once the minor reaches the designated age, full control passes to them automatically.
Why 18 Is the Practical Threshold
Nearly every meaningful business action involves a contract. Signing a lease, agreeing to supplier terms, hiring employees, accepting a loan. Under common law principles followed in every state, a person under 18 generally lacks the capacity to be bound by a contract. Any agreement a minor signs is voidable at the minor’s option: they can honor the deal or walk away, and the counterparty has no legal recourse.
This one-sided arrangement makes landlords, lenders, and vendors extremely cautious. A landlord who rents to a minor-owned business knows the lease could be canceled at any time. A bank knows a promissory note may be unenforceable. Most counterparties refuse to deal directly with a minor, or they insist an adult co-sign every agreement.
The voidability problem doesn’t last forever. Once a minor turns 18, they have a limited window to either disaffirm contracts made during minority or let them stand. Failing to disaffirm within a reasonable time counts as implied ratification, making the agreement fully enforceable going forward. A young owner approaching their 18th birthday should review every outstanding contract and decide which to keep while the option still exists.
Who Signs the Formation Paperwork
Creating an LLC or corporation means filing formal documents with a state agency, typically the Secretary of State. The person who signs and submits those documents is the incorporator (for a corporation) or the organizer (for an LLC). State statutes don’t usually set an explicit age floor for that role, but because signing formation documents is itself a legal act and a minor’s legal acts are voidable, the practical effect is the same as a prohibition. A Secretary of State’s office may reject papers signed by someone under 18, and even if the filing goes through, the minor could later void the entire formation.
The standard workaround is straightforward. A parent or other adult acts as the incorporator, signs the articles, and pays the filing fee, which generally runs from about $50 to $500 depending on the state. Once the entity exists, the ownership interests are issued to the minor. The adult who signed the formation papers doesn’t need to retain any ownership stake or ongoing role unless they also serve as a manager or officer.
Who Can Serve as Manager or Director
Managing a company is an active responsibility that comes with fiduciary duties, meaning a legal obligation to act in the company’s best interest. Most states require corporate directors and LLC managers to be at least 18. The logic follows from the contract problem: a person who cannot be held to a contract cannot reliably discharge duties that involve making binding commitments on behalf of the company and its stakeholders.
An officer or director who breaches their duty of care or duty of loyalty can be sued. If that person is a minor, the lawsuit runs into the same enforceability issues that plague every other contract. Investors, business partners, and creditors rely on the assumption that management can be held legally accountable.
The practical structure for a minor-owned company is to appoint an adult as the managing member of the LLC or sole director of the corporation. The minor keeps full economic ownership and can participate in decisions informally, but the adult’s name appears on the legal documents that require signatures. When the minor turns 18, they can step into the management role themselves.
Sole Proprietorships for Younger Founders
Not every teenage business needs an LLC or corporation. A sole proprietorship requires no formation paperwork at all. A 14-year-old who mows lawns, sells art online, or tutors classmates is operating a sole proprietorship by default. There’s no filing with the state and no minimum age to get started.
The trade-off is that a sole proprietorship offers no liability protection and still runs into the same contract capacity issues. A minor operating one cannot sign an enforceable lease or enter binding supplier agreements alone, and may need a parent on the bank account. For small operations those limits matter less. The teenager selling handmade candles at a farmers’ market doesn’t need a commercial lease.
Once a business involves employees, significant inventory, or real liability exposure, operating without a formal entity becomes risky. That’s the natural point where a parent steps in to help form an LLC and takes the management role until the owner is old enough to take over.
Bank Accounts and Payment Processing
Opening a business bank account as a minor is difficult in practice even when it isn’t explicitly prohibited. Most banks require the account holder to be 18. Personal accounts can often be opened jointly or through a custodial arrangement, but business checking accounts don’t always offer those options, and policies vary widely by institution.
The common workaround is for the parent to open the business account as the managing member or authorized signer, then add the minor with limited access. The same pattern applies to payment processors, merchant accounts, and business credit cards, all of which have age requirements in their terms of service. Financial institutions enforce these rules because they need the account holder to be bound by the account agreement; a minor could theoretically disaffirm the banking relationship, leaving the bank in a complicated position over overdrafts and disputed transactions.
Taxes Apply Regardless of Age
The IRS does not care how old a business owner is. A minor who earns money from a business owes the same taxes as an adult, and filing thresholds are low enough that even modest operations trigger obligations.
Any individual with net self-employment earnings of $400 or more in a year must file a tax return and pay self-employment tax, which covers Social Security and Medicare contributions. This applies regardless of age, even if the business owner is a teenager claimed as a dependent on a parent’s return.1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) A 15-year-old who nets $500 from a lawn care business owes self-employment tax on that income and needs to file Schedule SE.
If a minor’s ownership stake generates unearned income, meaning dividends, passive distributions, or investment gains rather than compensation for work, the kiddie tax may apply. For 2026, a child’s unearned income above $2,700 is taxed at the parent’s marginal rate rather than the child’s typically lower rate.2Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income The rule applies to children under 19, or under 24 if they’re full-time students, and exists to prevent parents from shifting investment income to their kids to capture lower brackets.
The distinction between earned and unearned income matters. Compensation for actual work in the business is earned income and not subject to the kiddie tax. Passive distributions from a company the minor owns but doesn’t work in are unearned income and get taxed at the parent’s rate once they cross the $2,700 line.2Internal Revenue Service.

Child Labor Rules When the Owner Also Works
Federal child labor laws under the Fair Labor Standards Act apply to minors who work, and that includes minors who work in their own businesses. The basic federal framework for non-agricultural work sets the general minimum employment age at 16 for most jobs, with limited hours and restricted job types for 14- and 15-year-olds.3U.S. Department of Labor. Fact Sheet #43 – Child Labor Provisions of the Fair Labor Standards Act (FLSA) for Nonagricultural Occupations No one under 18 may work in occupations the Secretary of Labor has declared hazardous.
There is a family-business exception. Children of any age may work for a business entirely owned by their parents, subject to two limits: children under 16 cannot work in mining or manufacturing, and no one under 18 can work in hazardous occupations even in a parent-owned business.3U.S. Department of Labor. Fact Sheet #43 – Child Labor Provisions of the Fair Labor Standards Act (FLSA) for Nonagricultural Occupations This parental exemption applies only to sole proprietorships and partnerships where the parent is the actual owner. It does not apply to corporations or LLCs, even if the parent owns all the equity, because the entity itself is treated as the legal employer.
State child labor laws often add further restrictions, including work permit requirements and stricter limits on hours during the school year. A young founder who plans to hire other minors also has to comply with these rules for their employees.
Emancipation as a Narrow Exception
A minor who has been legally emancipated, typically through a court order, may gain full or near-full contractual capacity depending on the state. Emancipation essentially treats the minor as an adult for legal purposes, which can remove the barriers to signing contracts, serving as a manager, and filing formation documents. The specifics vary by jurisdiction; some states grant emancipated minors complete legal capacity, others grant it only for certain purposes.
Emancipation is not a route designed for business formation. Courts grant it in situations where a minor is already living independently, is married, or is serving in the military. A teenager who simply wants to start a company won’t qualify on that basis alone. For a minor already emancipated for other reasons, though, the expanded legal capacity removes most of the obstacles described above.
