Work through this in order. Check each box as you go. Don't skip steps.
Will you operate as a sole proprietor (just yourself, no paperwork) or form an LLC or corporation? If you're not sure, start as a sole proprietor — you can always upgrade later.
If you're using a name other than your own legal name, you need to register it. Check with your county clerk's office.
Go to IRS.gov → search "EIN application." It's free and takes 5 minutes. Many cities require it to apply for a business license.
Search "[your city] business license" — find the official .gov website. Apply there. This is the main license most people need.
Most states don't have a general statewide business license — but some do (Nevada, Washington, Tennessee). Check the state guide for your state.
If you sell physical products, register with your state's department of revenue to collect sales tax. This is separate from your business license.
Restaurants need health permits. Contractors need contractor licenses. Childcare needs additional state licensing. Look up what your specific industry requires.
Almost all licenses renew annually. Set a calendar reminder NOW for 11 months from today. A missed renewal = a fine.
Once you've done all of these, you're legally operating. Keep your license documents in a folder (physical and digital) and check them each year at renewal time.
