Quick answer: it depends on where you live and what you do. Many cities and counties require a general business license even for a small, home-based side hustle, and states license specific trades such as cosmetology, contracting, real estate and food sales. You may also need a sales tax permit if you sell taxable goods, a home occupation permit under local zoning rules and a DBA registration if you use a business name. The U.S. Small Business Administration says most small businesses need a mix of licenses and permits from federal, state and local agencies, so check all three levels before you start.
Few side hustlers think about licenses until someone asks for one. A client wants proof you are registered, a farmers market requests a permit number or a neighbor mentions the city’s rules for home businesses. By then, you may already be operating without paperwork you were supposed to have.
The good news is that most side hustles need only a few registrations, and they are usually inexpensive. This guide explains the main types, who issues them and how to find out exactly what applies to you. It is part of our startup series linked from the main side hustle ideas guide, which covers choosing a hustle, landing customers and handling taxes.

The Short Answer: It Depends on Location and Activity
There is no single national business license in the United States. Licensing happens at three levels of government, and each level regulates different things:
- Federal agencies license a short list of highly regulated activities.
- States license many professions and trades, and they handle sales tax registration and entity formation.
- Counties and cities issue general business licenses, zoning approvals, health permits and many local registrations.
Two questions drive everything: where the business is based and what it actually does. A freelance copywriter working from a laptop in one city might need only a local business tax registration. A home baker in another state might need a cottage food registration, a sales tax permit and a home occupation permit. Same “side hustle” label, very different paperwork.
Federal Licenses: Rare for Side Hustles
The SBA explains that businesses only need a federal license or permit when an activity is regulated by a federal agency. Its list includes:
- Agriculture involving the import or interstate transport of animals, animal products, biologics or plants (U.S. Department of Agriculture)
- Alcoholic beverages, including manufacture, wholesale, import or retail sale (Alcohol and Tobacco Tax and Trade Bureau)
- Aviation, such as transporting goods or people by air (Federal Aviation Administration)
- Firearms, ammunition and explosives (Bureau of Alcohol, Tobacco, Firearms and Explosives)
- Fish and wildlife activities and commercial fishing (U.S. Fish and Wildlife Service; NOAA Fisheries)
- Maritime transportation (Federal Maritime Commission)
- Mining and drilling on federal lands (Bureau of Safety and Environmental Enforcement)
- Nuclear energy (Nuclear Regulatory Commission)
- Radio and television broadcasting (Federal Communications Commission)
- Oversize or overweight vehicle operation (state permits, with U.S. Department of Transportation guidance)
Most side hustles, such as tutoring, design, pet care, cleaning, reselling and online services, do not touch any of these. One activity worth noting: flying a drone for paid work, like real estate photos, generally requires FAA certification under its small drone rules, so drone photography hustles should check the FAA’s requirements.
State Licenses and Registrations
States regulate a wider range of activities than the federal government. Here is what to check at the state level.
Professional and occupational licenses
Many occupations require a state license regardless of business size. Common examples include cosmetology and barbering, massage therapy, real estate sales, insurance sales, contracting and home improvement, electrical and plumbing work, child care, counseling and many health-related services. The SBA lists construction, dry cleaning, farming, plumbing, restaurants, retail, auctions and vending machines among activities commonly regulated at the state and local level.
If your hustle is in a licensed field, operating without the license can bring fines and may void contracts. Check your state licensing board before taking your first paying customer.
Sales tax permit
If you sell taxable goods, and in some states certain services, you will usually need a sales tax permit, also called a seller’s permit, from your state department of revenue. This applies to many crafters, resellers and online shop owners. Some marketplaces collect and remit sales tax for you under state marketplace facilitator laws, but that does not always cover sales through your own website or in person. Check your state’s rules.
Entity registration
If you form an LLC or corporation, you register with your state, usually through the secretary of state. The SBA notes that registration costs are usually under $300, though fees vary by state and structure. Sole proprietors using their own legal name generally do not register an entity at all. Our comparison of sole proprietor vs LLC for side hustles covers when forming an LLC makes sense.
Cottage food rules
Home-based food businesses are often covered by state cottage food laws. These typically list which low-risk foods you can make at home, where you can sell them, labeling requirements and sometimes annual sales caps or registration. Rules differ widely, so check your state agriculture or health department.
Local Licenses and Permits
Local requirements catch the most side hustlers by surprise, because they can apply even to tiny, home-based businesses.
General business license or business tax registration
Many cities and counties require any business operating within their limits to register and obtain a general business license, sometimes called a business tax certificate. Fees vary and some are based on revenue. Your city or county clerk’s website usually explains who must register.
Home occupation permit and zoning
The SBA points out that zoning ordinances can still apply to home-based businesses. Many cities require a home occupation permit, which may limit customer visits, signage, employees, parking or the share of your home used for business. Working quietly on a laptop rarely causes problems; having clients arrive at your door or storing inventory in the garage might.
Renters and homeowners should also check their lease or homeowners association rules, which can restrict business activity separately from city law.
Health and safety permits
Food service, mobile vending, personal care services and child care often need local health department permits or inspections. Event-based hustles, such as selling at markets or festivals, may need temporary vendor permits.
Business Name Registration (DBA)
If you operate under any name other than your own legal name, you will probably need to register it. The SBA describes a DBA, or “doing business as” name, as a trade name, fictitious name or assumed name registered with your state, county or city. A DBA does not create legal protection by itself, but the SBA says most states require registration if you use one.
For example, someone named Maria Lopez offering design work as “Maria Lopez Design” may not need a DBA in some places, while “Bright Fern Studio” almost certainly would. A DBA plus an EIN can also make it easier to open an account in the business name, as covered in our guide to a separate bank account for your side hustle.
How to Find Out What You Need
Follow these steps to build your own checklist:
- Describe your activity precisely. “Selling handmade candles online and at two weekend markets” is more useful than “crafts.”
- Check federal relevance. Compare your activity with the SBA’s federal list. Most hustles can stop here.
- Visit your state’s business portal. Many states run a one-stop website that lists licenses by business type. Your secretary of state site is a good starting point.
- Search your state licensing boards. If your work is a recognized trade or profession, confirm whether you need a license.
- Check your department of revenue. Find out whether your goods or services are taxable and how to register for a sales tax permit.
- Contact your city or county. Look up general business licenses, home occupation permits and zoning rules. A quick call to the clerk or planning office can save guesswork.
- Ask your local Small Business Development Center. SBDCs, supported by the SBA, provide free or low-cost guidance and know local requirements.
- Write it down and set renewal reminders. The SBA notes that some licenses expire after a set period, and renewing is usually easier than reapplying.

Examples by Side Hustle Type
These general examples show what each kind of hustle commonly needs to check. Actual requirements depend on your location.
| Side hustle | Commonly checked |
|---|---|
| Freelance writing, design or virtual assistance | Local business license or tax registration; DBA if using a business name |
| Selling crafts or resale goods | Sales tax permit; local business license; market vendor permits |
| Home baking or food sales | State cottage food rules; health permits; sales tax; home occupation permit |
| Hair, makeup, nails or massage | State professional license; local business license; health or salon rules |
| Handyman or home repair | State contractor or trade license above certain job sizes; local license; insurance |
| Pet sitting or dog walking | Local business license; some cities regulate kennels or animal boarding |
| Drone photography | FAA small drone certification; local business license |
| Child care in your home | State child care licensing; local zoning |
What Happens If You Skip a License
Operating without a required license can lead to fines, back fees or an order to stop until you comply. In licensed professions, the consequences can be more serious. Unlicensed work may also cause problems with insurance claims or with enforcing payment from a client. Getting registered up front is usually cheap compared with sorting out a problem later.
Licenses, Insurance and Other Startup Steps
A license shows you are allowed to operate; it does not protect you financially. The SBA notes that business insurance can fill gaps, and that home-based businesses can sometimes add a rider to homeowners insurance or buy a business owner’s policy. Clients in some fields ask for proof of liability insurance before hiring.
Licensing also fits into a broader startup checklist: choose a structure, register any business name, get licenses, set up banking and bookkeeping and plan for taxes. Our guide to tracking side hustle income and expenses covers the record-keeping side, and license fees are generally a deductible business expense.
Frequently Asked Questions
Frequently Asked Questions
Do I need a business license for a side hustle? Often, yes, at the local level. Many cities and counties require a general business license or tax registration for any business, including home-based ones. Your state may also require a professional license or sales tax permit depending on what you do.
Do I need a business license to sell online? Selling online does not remove local and state requirements. You may need a local business license where you are based and a sales tax permit from your state, even if you only sell through a marketplace.
How much does a business license cost? It varies by city, county and state. Some local licenses cost a modest flat fee, while others are based on revenue. The SBA says state business registration usually costs less than $300.
Do I need a DBA for my side hustle? If you use a business name other than your own legal name, most states require you to register it as a DBA with the state, county or city.
Can I run a side hustle from my apartment? Usually, but check local zoning for home occupation rules and read your lease. Some landlords and HOAs restrict business activity, customer visits or signage.
Where can I get free help with licensing? Your local Small Business Development Center, SCORE mentors and your state's business portal can help you identify the licenses and permits that apply.
The Bottom Line
Most side hustles need at least one registration, usually a local business license, and some need state licenses, sales tax permits or zoning approvals. Start with a precise description of what you do, then check federal, state and local requirements in that order. It takes an afternoon, it is usually inexpensive and it lets you grow the hustle without worrying about a fine or a stop order later.
