Small Business Ideas for Teens and Young Founders

Ten ways to start small, with the first steps, a starter kit and the local rules to check for each.

The short answer

Many young people start with a low-cost, service-based business that needs little equipment, such as lawn care, pet sitting, mobile car washing or tutoring. Others start with a skill, like helping local shops with social media or learning automation tools. This page compares ten ideas: what each involves, what people typically start with, and which local rules to check first.

Important

This article is general information for founders, not legal, tax, or financial advice. Rules, fees, and filing requirements vary by state and change over time. Nothing here creates a professional relationship of any kind. Confirm anything that affects your business with your state's filing office and a qualified attorney or accountant before you act on it.

Many young founders involve a parent or guardian from the start, since rules about contracts, bank accounts and online accounts often depend on age.

Ten ideas, compared

Which business ideas can young people start with little money?

Each idea has its own guide. This table is the quick comparison, and the cards below it are grouped by the kind of work involved.

Idea Age guide Startup cost Where it happens What people typically bring
Mobile car wash 14+ Low At the customer's home or workplace Buckets, wash mitts, towels and a way to get water
Mobile car detailing 15+ Moderate At the customer's home or workplace Towels, interior and exterior products, a vacuum and a way to get water
Mobile mechanic 18+ Higher At the customer's home or workplace, usually from a van Tools, a work vehicle, parts and training
Lawn care 12+ Moderate Outdoors at customers' homes A mower, a trimmer, a rake and safety gear
Pressure washing 16+ Moderate Outdoors at customers' homes and shops A pressure washer, hoses, nozzles and a plan for the wash water
Pet sitting and dog walking 13+ Low Around the neighborhood or in the pet's home Leashes, waste bags, a phone and a written plan for each pet
AI automation and vibe coding 13+ Low On a laptop, for local businesses A laptop, starter-level tool accounts and curiosity
Social media help for local shops 16+ Low On a phone or laptop, for local businesses A phone, a few apps and a client's permission
Tutoring 14+ Low At a library, online, or at home with a parent nearby Subject knowledge, patience and a plan for each session
Reselling 13+ Low Online, by mail or at a local pickup Items to sell, a phone for photos and packing supplies

Startup cost labels are our own grouping, not price quotes: low usually means mostly things a person may already own, moderate means buying some specialist equipment such as a mower, a pressure washer or a polisher, and higher means a work vehicle, a full set of tools and insurance. Age guides are a general starting point with a parent or guardian involved, not a legal rule. Both vary by place.

Narrowing it down

How do you choose a business idea?

There is no single right answer, but these are the questions young founders commonly start with.

What can you already use or borrow?

Some ideas start with things many households own, like a phone, a laptop or a mower. Others involve a vehicle or specialist tools, which changes the cost and the age guide.

How many hours can you give it?

Weekend jobs and after-school work suit different ideas. Seasonal work, like lawn care, follows the weather, while tutoring follows the school calendar.

Outdoors, with people, or on a screen?

The ideas split roughly into hands-on work outside, work for local businesses on a computer, and buying, selling or teaching. Pick the kind of day that sounds bearable on a bad week.

Who could your first three customers be?

Neighbors, family friends and local shops are where many young founders begin. If a first customer is easy to name, the idea is usually easier to test.

Before you start

What should you know before you start?

Age and contracts

In general, a contract with a minor is voidable, meaning the minor may be able to cancel it while the other side generally cannot, and the details vary by state. That is why businesses and banks often ask a parent or another adult to co-sign. The age of majority is usually 18, including in Nevada, but a few states set it higher, so the rule in your state is worth checking.

Taxes

The IRS says people usually must pay self-employment tax if they had net earnings from self-employment of $400 or more, and that these rules apply no matter how old you are. It also says income from goods you sell or services you provide is reportable whether or not a payment app sends a Form 1099-K. Figures are as of October 2026, so confirm current ones.

Licenses, permits and zoning

The SBA says the licenses and permits a business needs depend on its activities and location, and that local governments determine registration, licensing and permitting requirements. Zoning rules can apply even to home-based businesses. As one example, the Las Vegas Municipal Code has a chapter for mobile car wash and auto detail businesses that calls for a city license. Other cities differ. How the two common business setups compare.

Insurance and liability

Insurance regulators warn that a homeowners or renters policy may not cover a home-based business, and Michigan's insurance department says most home insurance policies exclude business activities conducted on a regular basis in the home. Triple-I, an insurance education group, adds that a personal auto policy is designed for personal rather than commercial use, which can matter for ideas that involve a vehicle. An insurance agent can explain what policies exist.

Getting paid

Banks and credit unions commonly involve a parent or other adult as co-owner or custodian for customers under 18, because account agreements follow state law. Payment apps set their own age rules: as of October 2026, PayPal says an account holder must be at least 18 or the age of majority in their state, while Venmo and Cash App offer teen accounts that a parent or guardian is linked to or sponsors, and Venmo says personal and teen accounts may not be used for business transactions with other personal accounts.

Advertising and reviews

The FTC says advertising must be truthful and not deceptive, advertisers must have evidence to back up their claims, and ads cannot be unfair. Its rule on consumer reviews and testimonials, which took effect in October 2024, addresses fake or purchased reviews and buying fake social media followers.

Common questions

Frequently asked questions

What are good business ideas for teens?

Teens often start with low-cost services close to home, such as lawn care, pet sitting and dog walking, tutoring, or reselling things they already own, often with a parent or guardian's help. Ideas that depend on a vehicle, heavy equipment or specialist skills, such as mobile mechanic work, usually suit older or more experienced founders. The ten ideas on this page are grouped by how much equipment and experience each one tends to involve.

How old do you have to be to start a business?

There is no single age. The age of majority is usually 18, including in Nevada, and a contract with a minor is generally voidable, so banks, payment apps and customers often ask for a parent or guardian. Many young founders start earlier with an adult's help, and platforms, cities and states can set their own age limits, which is why each idea guide lists the rules it found.

What business can a 15-year-old start?

Many 15-year-olds start with low-cost services close to home, such as pet sitting and dog walking, lawn care, tutoring or mobile car washing, with a parent or guardian involved. The age guides on this page are editorial starting points, not legal rules. Online platforms set their own minimum ages, and several marketplaces say sellers or tutors must be 18, so each idea guide lists the ones that apply.

What is the cheapest business to start?

Service businesses that rely on time and skills rather than inventory usually cost the least to start. Lawn care, pet sitting, tutoring and social media help can often begin with things people already own, while mobile car work, mechanic work and pressure washing tend to involve more equipment. Actual costs vary by place and by how much equipment a person chooses to buy.

Do teenagers have to pay taxes on a small business?

The IRS says people usually must pay self-employment tax if they had net earnings from self-employment of $400 or more, and that these rules apply no matter how old you are. It also says income from goods you sell or services you provide is reportable whether or not a payment app sends a Form 1099-K. These figures are as of October 2026, so confirm current ones with the IRS or a tax professional.

Do you need an LLC to start a small business?

Not always. A sole proprietorship, where the owner and the business are legally the same, generally does not require a state formation filing, while an LLC does. Either one can still involve local licenses or permits. Which structure fits depends on the business, the state and the owner's situation, so it is worth reading both comparisons and asking a qualified attorney or accountant.

How do young founders find their first customers?

Many of these ideas begin with people already nearby: neighbors, family friends, local shops and community groups, then grow through repeat visits and referrals. Ideas aimed at businesses, such as social media help or automation, often start with one local shop or team that already knows the founder.
