20 Business Ideas for Teens (and the Rules to Check First)

Twenty realistic business ideas for teens, with who they're for, how to start small, how they earn and the hard part, plus age, consent and safety checks.

The best business ideas for teens are small services for people who already know you: pet sitting, tutoring younger kids, garden tidying, tech help for neighbours, or making and selling something you're good at. They cost little to start, fit around school, and are easy for a parent to keep an eye on. Before you take any money, check the rules where you live with a parent or guardian: minimum ages for work, whether you need their consent, how you'll get paid, and whether you owe tax. Below are twenty realistic ideas, each with who it's for, how to start small, how it earns and the honest hard part.

This guide is for people roughly 13–17. It doesn't include anything that needs you to borrow money, invest, or sell restricted products, and you shouldn't take on anything like that without an adult who knows the rules.

Check these first

Check	Why it matters	Where to look
Age rules for work	Many places limit the jobs, hours and times young people can work	In the US, the Department of Labor's YouthRules site; elsewhere, your government's youth employment pages
Parent or guardian consent	Contracts, accounts and registrations often need an adult	Talk to your parent first; they may need to sign or open accounts
Getting paid	Many payment services require you to be 18	Stripe, for example, lets 13–17-year-olds open a standard account only with a guardian as owner (Stripe's age rules)
Platform age limits	Marketplaces, social media and website builders set minimum ages	Read each platform's terms before you sign up
Tax	Business income may need reporting, even small amounts	Ask a parent or a tax adviser; keep records from day one
Food and safety rules	Selling food or working with animals or children can have extra rules	Your local council or health authority

Stay safe

Work for people you or your family know, or through a parent's network, at least at first.
Tell a parent where you're going, who the customer is and when you'll be back. Never go into a stranger's home alone.
Keep personal details private. Don't post your home address, school or phone number publicly. Use a parent-approved email for enquiries.
Agree the price before you start, and write it down.
Say no to anything that feels wrong, involves risky tools or machinery, or asks you to pay money upfront to "join" an opportunity.

Services for neighbours

1. Pet sitting and dog walking

For: Busy families and people away for a weekend.
Start small: Walk one neighbour's dog for a week. Ask for a short written note of what the pet needs. How to start a dog walking business covers the basics.
Earns: Per walk or per visit.
Hard part: Responsibility. Lost or injured pets are serious; start with calm dogs you know, one at a time.

2. Garden tidying and leaf clearing

For: Older neighbours, busy families.
Start small: Weeding, raking, watering while people are away. Use hand tools only.
Earns: Per job or per hour.
Hard part: Seasons and safety. Leave power tools like mowers and hedge trimmers to adults unless your local rules and a parent say otherwise.

3. Tech help for older neighbours

For: People who want help setting up a phone, video calls or a new TV.
Start small: Offer one hour at a relative's or family friend's house, with a parent aware.
Earns: Per session.
Hard part: Trust and privacy. Never ask for or write down passwords or bank details; let them type their own.

4. Car washing at home

For: Your street.
Start small: Buckets, sponges and a weekend morning. Charge per car.
Earns: Per wash; a bit more for interiors.
Hard part: Weather and repeat customers. Offer a monthly slot.

5. Babysitting or parent's helper

For: Families you know with young children.
Start small: Be a "parent's helper" while a parent is at home, before you babysit alone. A first aid or babysitting course helps.
Earns: Per hour.
Hard part: It's a big responsibility. Some places have guidance on minimum ages for looking after children alone; check before you do it.

6. Party and event helper

For: Families running children's parties or garden events.
Start small: Help set up, run games, tidy up.
Earns: A flat fee per event.
Hard part: Getting booked again. Ask happy hosts to recommend you.

Teaching and tutoring

7. Tutoring younger students

For: Parents of primary or younger secondary students.
Start small: One subject you're strong in, one student, at their home with a parent present or online with parents' permission. How to start a tutoring business has more.
Earns: Per session.
Hard part: Preparation. Plan each session; parents notice.

8. Music or instrument lessons for beginners

For: Young beginners whose parents want a low-cost start.
Start small: The very basics on an instrument you've played for years.
Earns: Per lesson.
Hard part: Knowing when to refer a student to a proper teacher.

9. Sports or swim practice buddy

For: Younger kids who want extra practice in a sport you play.
Start small: Practice sessions at a park, with a parent present.
Earns: Per session.
Hard part: Safety. Anything in water or with real injury risk needs qualified adults; stick to practice, not coaching.

Making and selling

10. Handmade crafts

For: Friends, family, school fairs, local markets.
Start small: Ten items (bracelets, cards, keyrings, prints), sold at one school or community event.
Earns: Per item. Work out materials cost first, then price.
Hard part: Pricing your time. Most beginners charge too little.

11. Baked goods for events

For: Bake sales, family events, neighbours' orders.
Start small: Bake for a school or charity bake sale first.
Earns: Per item or per order.
Hard part: Food rules and allergies. Selling food regularly often needs registration or hygiene rules; label allergens clearly and ask your local council.

12. Plant cuttings and seedlings

For: Gardeners and plant lovers nearby.
Start small: Grow cuttings from plants you already have; sell them at a stall outside your home with a parent's OK.
Earns: Per pot.
Hard part: Patience; plants take weeks.

13. Selling things you've outgrown

For: Anyone; you're decluttering.
Start small: Clothes, games and books you no longer use, sold through a parent's account or a school sale.
Earns: One-off sales.
Hard part: Most resale platforms require you to be 18 or use an adult's account. Check the terms.

Digital and creative

14. Video editing for creators

For: Local clubs, family businesses, creators you know.
Start small: Edit one short video free as a sample, then charge per video.
Earns: Per video.
Hard part: Clear briefs. Agree length, style and how many changes are included.

15. Photos for small businesses

For: Local cafés, shops and clubs that need better photos.
Start small: Shoot one business you know, with a parent coming along.
Earns: Per shoot.
Hard part: Getting permission. Ask before photographing people, and agree who can use the photos.

16. Simple websites for clubs and family businesses

For: A sports club, a relative's business, a school society.
Start small: Build a one-page site with what they do, when, where and a contact form. The website builder or landing page builder are good starts, and website ideas has more options.
Earns: A set-up fee, plus a small amount for updates.
Hard part: Age limits on tools and domains. Mythex's terms require users to be at least 16 (or the age of digital consent in your country), and buying a domain usually needs an adult's account and card.

For: Small businesses that know they should post but don't.
Start small: Plan and draft a month of posts for one business you know; they approve and post from their own account.
Earns: A monthly fee.
Hard part: Account access. Don't take passwords to someone else's accounts; let them post, or use the platform's own team access with a parent's agreement.

18. Study tools you build yourself

For: Students at your school.
Start small: A flashcard or revision tracker for one subject. How to build a flashcard app shows how, and side project ideas you can build with AI has more.
Earns: Usually nothing at first; it's great practice and something to show for college or job applications.
Hard part: Other students' data. Don't collect more than you need, and get permission from your school before you promote it there.

Community

19. Organising a local event

For: Your neighbourhood: a gaming tournament, a car-boot table, a book swap.
Start small: One event with a parent or teacher co-organising.
Earns: Small entry fees or table fees, or nothing if it's for charity.
Hard part: Venues, safety and permissions. An adult needs to be in charge of anything public.

20. Errands and grocery runs

For: Neighbours who find shopping hard.
Start small: One regular weekly run for someone your family knows.
Earns: A fee per trip, with receipts for everything you buy.
Hard part: Handling other people's money. Always give receipts and change back.

How to start (the safe way)

Pick one idea you can do this month with things you already have.
Talk to a parent or guardian. Agree what's allowed, who your first customers are, and how you'll get paid.
Check the rules in the table above for where you live.
Do one job for someone you know. Ask for honest feedback and, if it went well, a recommendation. How to get your first 100 customers has more ideas for later.
Keep a notebook or spreadsheet of every job, what you were paid and what you spent.
Make a simple flyer or page with what you offer and a parent-approved way to contact you. Don't include your home address.

Start small, stay safe, and treat your first customers well. Most good teen businesses grow from word of mouth.

Questions

What is the best business for a teenager to start?

A simple service for people who already know and trust you: pet sitting, tutoring younger students, garden tidying, or helping neighbours with phones and computers. These need little or no money to start, you can do them around school, and a parent can easily keep an eye on things.

Can a teenager legally run a business?

It depends on where you live and on your age. Doing small jobs for neighbours is usually fine, but signing contracts, opening bank or payment accounts, registering a business and paying tax often involve a parent or guardian. Check your country's or state's rules with a parent before you take money.

How can a teen accept payments online?

Usually with an adult's help. Many payment services require account holders to be 18. Stripe, for example, lets people from 13 create a standard account, but a legal guardian must add themselves as the owner before it can accept charges or pay out to a bank. Cash, or a parent's account with their agreement, is simpler for small jobs.

Do teens have to pay tax on business income?

Possibly, even at small amounts, depending on your country's rules. Keep a simple record of what you earn and spend from the first job, and ask a parent or a tax adviser what applies to you.

Can a teen build a website for their business?

Yes, and it's a good skill to learn. Check the age rules of any tool you use first; many website and app builders, including Mythex, set a minimum age in their terms. A one-page site with what you offer, your area and a contact form that goes to a parent's email is a safe start.
