Licenses & permits

Almost every business needs some combination of federal, state, or local licenses or permits. The hard part is not reading a list from 2011 — it is finding your current list for your place and industry.

By Rich Thurman, who spent about 15 years at Microsoft as an application-development consultant and has helped about 1,500 small businesses automate the busywork that eats their week. He still builds real software, AI and data systems today.

Rules change and can differ by state. Before you act, check with your state, SBA.gov, or a lawyer. This guide is a simple starting point, not legal advice. Licensing pages and fees change. Do not treat archived guides, old bookmarks, or AI summaries as the final word. Confirm on official state and local sites before you file or open.

How to find what you need

  1. Start with your state “business” or “one-stop” portal. Search [your state] business license or start a business on the official .gov site.
  2. Check your city and county. Local business licenses, zoning, health, and sign permits often sit here — not at the federal level.
  3. Check your industry. Food, childcare, construction, alcohol, healthcare, transportation, and many trades have extra boards or agencies.
  4. Ask whether federal licensing applies. Most small local businesses do not need a federal operating license; some activities (for example certain transport, agriculture, firearms, broadcasting) do. When unsure, check current federal agency guidance for your activity — or ask counsel.
  5. Bundle registration steps. Entity formation, DBA/name registration, EIN (IRS), state tax/seller permits, and licenses often travel together. See classic “steps to register” logic: structure → name → tax IDs → licenses.

Quick answers

Where do I start looking for the licenses I need?

Start with your state “business” or “one-stop” portal.

Where do local business licenses come from?

Check your city and county. Local business licenses, zoning, health, and sign permits often sit here — not at the federal level.

Do most small businesses need a federal license?

Most small local businesses do not need a federal operating license; some activities (for example certain transport, agriculture, firearms, broadcasting) do.

Is an EIN the same as a federal business license?

Many owners confuse an EIN (tax ID) with a federal business license. An EIN is common; a federal operating license is not, unless your activity sits under a specific agency.

Can I trust AI on license rules?

AI can help you draft a research checklist and explain jargon. It can also hallucinate agency names and fees. Always click through to the official site and save a dated copy of what you relied on.

Checklist while you research

  • ☐ State general business / privilege license (if any)
  • ☐ City or county business license
  • ☐ Professional or occupational license (if your trade requires one)
  • ☐ Sales tax / seller permit / vendor’s license
  • ☐ Home-occupation or zoning clearance (home-based)
  • ☐ Health, fire, building, or sign permits (if relevant)
  • ☐ Industry-specific federal permits (only if your activity is regulated)

What “federal” usually means

Many owners confuse an EIN (tax ID) with a federal business license. An EIN is common; a federal operating license is not, unless your activity sits under a specific agency. When archived lists mention agriculture, alcohol, aviation, firearms, fish and wildlife, or similar, treat them as clues to investigate — not as your personal to-do list.

Keep a paper trail

  • Save PDFs or screenshots of the official requirement pages (with dates).
  • Calendar renewal dates the day you get approved.
  • If you move cities or change activities, re-check — licenses often do not travel cleanly.
