Almost every business needs a license or permit to operate legally — including home-based businesses and freelancers. What you need depends on your location, industry, and business structure. Operating without the right licenses can lead to fines, forced closure, or even criminal charges. The upside: most licenses are straightforward to get once you know which ones apply.
Most cities and counties require a general business license (sometimes called a business tax certificate) for any commercial activity in their area. This is separate from state requirements and usually runs $50–$400 per year.
Food service, construction, childcare, healthcare, and alcohol sales are among many fields that require specific permits and inspections. Some need a professional license — like a contractor's license — with exams and experience requirements.
Working from home doesn't let you skip licensing. You may need a home occupation permit on top of a standard business license, and zoning laws can limit what types of businesses run from residential areas.
Selling online doesn't exempt you from licensing. You typically need a license in the state where your business is based, plus a sales tax permit if you sell taxable goods.
Requirements exist at all three levels of government, and meeting one level's rules doesn't satisfy the others. Start with the SBA website for federal rules, then check your state's business portal and your city or county clerk's office.

This shows whether your state makes every business obtain a single state-level general business license or registration, or instead leaves general business licensing to your city or county. Each value is cited to the state statute or agency; a state with no sourced figure shows "Not yet sourced."
