Do I need a business license?

In many cases, yes — but there is not one single "US business license" that covers every business.

What you may need depends on your state, city or county, your industry, and whether you sell regulated products or provide regulated services. Some owners need a general local business license. Others need industry-specific permits, tax registrations, zoning approval, or professional licensing.

A DBA is a "doing business as" name, which is a public filing that lets you use a business name different from your legal name or company name. A DBA is not the same thing as a business license.

This page is general educational information, not legal advice. For a decision about your business, check the rules with the relevant government office and, if needed, a licensed attorney.

The answer usually depends on a few practical questions:

• Where you work. A home-based online business may still need a city or county license, home-occupation permit, or local tax registration.
• What you sell. Food, alcohol, cosmetics, transportation, childcare, health services, and construction often have extra permits or inspections.
• How your business is structured. An LLC is a limited liability company, a legal business structure created under state law. A C-corp is a corporation taxed under Subchapter C of the Internal Revenue Code. An S-corp is a tax election that can allow an eligible corporation or LLC to be taxed under Subchapter S. Forming one of these entities does not automatically give you a business license.
• Whether you hire workers or collect tax. An EIN is an Employer Identification Number from the IRS, used to identify a business for federal tax purposes. You may also need state tax registration, payroll accounts, or sales tax permits.

If you are still choosing a structure, How to form an LLC in the US, LLC vs corporation: which is right, and What is an EIN and how to get one can help with the basics.

A person starts a small bakery from home and sells through social media.

They may need:

• a city or county business license
• a home-occupation permit
• health department approval
• a sales tax permit
• labeling compliance for packaged food

By contrast, a freelance graphic designer working from home may need fewer approvals, but could still need a local business license or tax registration.

The key point is simple: forming the company is only one step. For example, filing articles of organization — the document filed with a state to create an LLC — does not mean all license and permit requirements are finished.

If you want help spotting the legal issues, you can get matched for free with a licensed business-law attorney.

Start with the official sources:

1. Check your state Secretary of State website for entity and registration rules.
2. Check your city and county websites for local business license, zoning, and home-based business rules.
3. Check IRS.gov for federal tax registration information.
4. If your business is regulated, check the agency that oversees that industry.
5. If anything is unclear, talk with a licensed attorney.

Be careful with online forms and intake pages. Share only contact information and a short description of your issue at first — not your Social Security number, Individual Taxpayer Identification Number, EIN, immigration status, bank account numbers, or confidential business secrets.
