5 Business Licenses Most Service Businesses Need (And How to Get Them)

Starting a service business means navigating a confusing mix of licenses, permits, and registrations. The good news: most of them are straightforward to get. Here are the five that most service businesses need.

Important: Operating without required licenses can result in fines, forced closure, and denied insurance claims. It's not worth cutting corners. Most of these cost $50–$200 total and take a few days to process.

License 1: Business license (city or county)

Almost every city and county requires a general business license to legally operate. This is separate from any trade-specific license β€” it's just the permit to do business in that jurisdiction.

License 2: State business registration (LLC or DBA)

If you've formed an LLC, you registered with the state when you filed your Articles of Organization. If you're a sole proprietor operating under a name other than your legal name, you need a DBA ("doing business as") filing.

License 3: Federal EIN (Employer Identification Number)

An EIN is basically a Social Security number for your business. You need it to open a business bank account, hire employees, file business taxes, and often to get licensed at the state level.

Tip: Get your EIN even if you're a sole proprietor with no employees. Using your SSN on business documents and contracts exposes you to identity theft risk.

License 4: Trade or professional license (if required)

Most licensed trades require a state-issued professional license to perform regulated work. Whether you need one depends on your trade and state:

TradeTypically licensed?
Electrician, plumber, HVACYes β€” most states
Cosmetologist, esthetician, nail techYes β€” all states
General contractorYes β€” most states
Personal trainerNo (certification recommended)
Dog walker / pet sitterNo (most states)
House cleanerNo (most states)

License 5: Seller's permit (if you sell products)

If you sell physical products as part of your service β€” a cleaning company that sells cleaning kits, a stylist who sells hair products, a caterer who sells packaged foods β€” you likely need a seller's permit to collect sales tax.

Don't skip this: Collecting sales tax without a permit, or failing to collect it when you should, creates tax liability that compounds over time. When in doubt, consult a local CPA.
Bottom line: Budget one day and $100–$300 to get properly licensed when you start. It's a one-time investment in your business's legal foundation. Operating without required licenses puts everything you're building at risk.
