A minor who works for themselves plays by a different rulebook than a teen with a W-2 job. The core self-employment rules for minors are these: net earnings of $400 or more in a calendar year trigger a federal tax return and self-employment tax, contracts a minor signs are generally voidable, banks and payment platforms gate accounts behind an adult, and federal child labor hour limits don’t reach work the minor does for themselves. Everything else, from business registration to liability, flows from those four facts.
The $400 Filing Threshold
The IRS doesn’t care how old a self-employed earner is. If a minor’s net self-employment earnings hit $400 in a calendar year, they must file a federal tax return and pay self-employment tax.1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) That threshold catches many young entrepreneurs off guard because it’s far lower than the standard deduction that often shields W-2 teens from filing at all.2Internal Revenue Service.

Income and expenses get reported on Schedule C (Profit or Loss from Business), attached to a standard Form 1040.3Internal Revenue Service. Schedule C and Schedule SE Every legitimate business cost, from supplies to advertising to equipment, reduces net earnings and directly lowers the tax bill, so tracking expenses from day one matters. The minor files their own return even when a parent claims them as a dependent.
How Self-Employment Tax Is Calculated
The self-employment tax rate is 15.3%, covering both the employee and employer shares of Social Security (12.4%) and Medicare (2.9%).1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) It doesn’t apply to the full net earnings figure. The IRS first multiplies net earnings by 92.35% to reach the taxable base, mirroring the way a regular employee’s share of FICA is calculated after the employer pays its half.4Internal Revenue Service. Topic No. 554 – Self-Employment Tax A teen who nets $1,000 from freelance work therefore owes SE tax on roughly $923.
The whole calculation runs through Schedule SE, filed alongside Schedule C and the 1040. Half of the SE tax owed can also be deducted from adjusted gross income, which reduces regular income tax without reducing the SE tax itself.4Internal Revenue Service. Topic No. 554 – Self-Employment Tax
When Quarterly Estimated Payments Kick In
If the minor expects to owe at least $1,000 in total tax for the year after withholding and refundable credits, the IRS generally requires quarterly estimated payments.5Internal Revenue Service. 2026 Form 1040-ES Estimated Tax for Individuals The four due dates are April 15, June 15, September 15, and January 15 of the following year.6Internal Revenue Service. Estimated Tax Missing them triggers underpayment penalties and interest, even on amounts owed by a 14-year-old.
Most first-year teen businesses won’t clear that $1,000 mark. A side business that gains real traction mid-year is a different story, and the numbers are worth running before April rather than after.
The Social Security Credit Upside
Paying self-employment tax isn’t all downside. A self-employed person earning at least $400 in net earnings generally begins accumulating Social Security credits toward future retirement and disability benefits.7Social Security Administration.

What Federal Child Labor Rules Do and Don’t Cover
The Fair Labor Standards Act sets minimum ages, hour limits, and safety rules for working minors, but those provisions only apply when there’s an employer-employee relationship. A teenager who freelances, sells handmade goods, or runs a lawn care operation isn’t employed by anyone, so the FLSA’s scheduling restrictions don’t reach their own work hours. The Department of Labor’s guidance confirms that federal youth employment provisions “do not apply where no FLSA employment relationship exists.”8U.S. Department of Labor. Fact Sheet 43 – Child Labor Provisions of the Fair Labor Standards Act for Nonagricultural Occupations
Safety rules are a different matter. The FLSA broadly prohibits anyone under 18 from performing hazardous work, including operating heavy power-driven machinery and handling explosives, even outside a formal employment relationship.9U.S. Department of Labor. Age Requirements Some local governments also enforce “street trade” rules for minors who sell in public spaces or door-to-door. Violations can bring fines or a forced shutdown.
Contracts a Minor Signs Are Voidable
Contract law treats minors as lacking the legal capacity to enter binding agreements. Contracts they sign are “voidable,” meaning the minor can walk away without the penalties an adult would face. The rule exists to shield young people from predatory deals, but it creates a real obstacle to running a business. A client hiring a 16-year-old web designer knows the teen could abandon the project without legal consequence, and many businesses are reluctant to enter agreements directly with minors as a result.
The standard fix is having a parent or guardian co-sign or enter the contract on the minor’s behalf. The adult becomes the legally bound party, giving the other side an enforceable agreement. Without that adult guarantor, a young entrepreneur will struggle to lease equipment, secure vendor relationships, or land contracts with larger clients who need legal certainty.
One exception: contracts for necessities like food, clothing, shelter, and medical care generally cannot be voided by a minor. It rarely comes up in a business context, but a minor who signs a contract for something the law classifies as a necessity is likely stuck with it. Once a minor turns 18, contracts they haven’t yet voided typically become fully enforceable.
The voidability rule cuts both ways for creative work. A minor who creates original graphic design, music, photography, software, or written content owns the copyright from the moment of creation, with no minimum age.10Office of the Law Revision Counsel. 17 U.S. Code 201 – Ownership of Copyright If they license or assign that work through a contract they can later void, the transfer of rights is uncertain. A parent’s co-signature protects the client; the underlying copyright still belongs to the minor.
Banking and Payment Processors
Running a business requires somewhere to put the money, and this is where minors hit a wall. Most banks require account holders to be at least 18. A self-employed teen usually needs a parent to open a joint account or a custodial account where the adult manages the funds. Under the Uniform Transfers to Minors Act, adopted in some form by every state, assets can be held in a minor’s name with an adult custodian managing them until the age specified by state law.11Cornell Law School.

Payment processors set their own age gates. PayPal requires U.S. account holders to be at least 18 or the age of majority in their state.12PayPal. PayPal User Agreement Stripe allows users as young as 13, but only when an adult representative such as a parent is added to the account and agrees to be responsible for the minor’s compliance with Stripe’s terms.13Stripe. Stripe Services Agreement – General Terms A minor who creates an account by misrepresenting their age risks having it frozen and funds held.
Business Registration and Structure
Most self-employed minors operate as sole proprietors by default, which requires no formal filing. The business and the owner are legally the same. If the teen uses a commercial name other than their own legal name, they may need to register a Doing Business As (DBA) name with local or state authorities; fees vary widely by jurisdiction. Many local governments also require a general business license, again with fees that depend on locality and business type.
An Employer Identification Number is free from the IRS and gives the business a federal tax ID separate from the minor’s Social Security number.14Internal Revenue Service. Employer Identification Number It’s useful for opening business bank accounts, though a sole proprietor with no employees isn’t required to have one.
A Limited Liability Company offers liability protection a sole proprietorship doesn’t, but it introduces complications for minors. A handful of states explicitly bar anyone under 18 from serving as the organizer who files the formation paperwork. Most states’ LLC statutes say nothing about age, which technically leaves the door open, but the minor’s limited contracting capacity makes the practical process harder. A common workaround is having a parent act as organizer and registered agent while the minor is listed as owner or member.
Zoning is easy to overlook. Most residential zones allow home occupations only under specific conditions, with common restrictions on customer foot traffic, exterior signage, on-site inventory or equipment, and activities that create noise, odors, or extra parking demand. Rules come from local planning departments and vary widely. A teen selling handmade jewelry online from a bedroom is unlikely to draw scrutiny; a landscaping business storing commercial equipment in the driveway might.
Liability for the Teen and the Parent
A sole proprietor has no legal separation between personal and business liability. If the teen’s business causes property damage or injures someone, the teen is personally liable. Whether the parent is also on the hook is the more practical question. Under common law, parents are generally not liable for a child’s actions based on the family relationship alone. But several exceptions regularly swallow that rule:
- Parental negligence, where a parent knew or should have known the child’s business activity posed a risk and failed to supervise.
- Agency or direction, where the child is running the business at the parent’s direction or on the parent’s behalf, making the parent liable for acts within that scope.
- Dangerous instrumentality, where the parent provided tools or equipment that caused the harm.
Most states have also enacted statutes imposing some degree of automatic financial responsibility on parents for certain acts by their minor children, typically with dollar caps that vary by state. For a teen doing physical work on other people’s property, whether that’s lawn care, power washing, or pet sitting, the exposure is real. General liability insurance is available for sole proprietors and worth investigating once the work moves beyond casual and occasional.
The Custodial Roth IRA Payoff
Reported self-employment income opens a door most teens don’t have access to. Any minor with earned income, including self-employment income, can contribute to a custodial Roth IRA, opened and managed by a parent until the child reaches adulthood but owned by the minor. For 2026, combined annual contributions across all IRAs cannot exceed $7,500 or the minor’s total taxable compensation, whichever is lower.15Internal Revenue Service. Retirement Topics – IRA Contribution Limits
A 15-year-old who contributes $3,000 from lawn care earnings and never adds another dollar still has decades of tax-free growth ahead. Roth contributions come from after-tax dollars, but most teen earners have little income tax liability beyond the SE tax itself, so the effective cost of contributing is low. Every dollar contributed has to be backed by reported earned income, which is why the record-keeping that supports the tax return also unlocks the retirement account.
