Business Licenses by City: How the Biggest Cities License
In most of the country the license that lets you open the doors comes from city hall, not the state capitol. But no two big cities run licensing the same way: some license every business, some license none generally and regulate by activity, and several fold the license into the local tax system. These guides cover the largest markets one city at a time, and each pairs the city layer with the state requirements that sit above it.
Why the city layer is the confusing one
State licensing is at least documented in statute. City licensing is written in municipal codes, administered by departments with different names in every city, and often disguised as a tax registration rather than a license. The result is that the same question, does my business need a license here, has a different answer in New York than in Chicago, and a different issuing office in Los Angeles than in Philadelphia. The honest framing matters: city licenses are issued by the city to the operator, usually online and quickly, and no outside service can skip that step for you. What a licensing partner does is manage the state layer above it, keep the multi-city and multi-state stack coherent, and tell you exactly which local filing you still owe.
The three city licensing models
Big cities cluster into three models. Tax-certificate cities, Los Angeles, Philadelphia, Seattle, and Atlanta among them, require every business to register with the city's finance or revenue office and treat the certificate as the license. General-license cities, Chicago is the clearest example, issue a true business license with an application and review. And no-general-license cities, New York and Houston, license nothing across the board but regulate dozens of specific activities, so whether you need a city license depends entirely on what the business does.
The state layer still applies
Whatever the city requires, the state layer runs in parallel: entity registration with the secretary of state, a seller's permit or sales tax registration with the revenue agency, and industry licenses for regulated fields. A business can be perfectly licensed with the city and still be operating unlawfully at the state level, and the reverse. Each city guide links the matching state page so both layers get checked together.
Multi-city operators carry the stack in every market
A company operating in several cities holds each city's registration plus each state's licenses, and the renewal calendars do not line up. That portfolio problem is where Cornerstone's business licensing practice earns its keep: we run the state-level registrations, seller's permits, and industry licenses across every state, flag the local filings each market adds, and keep the calendar so no certificate lapses quietly.
The city guides
Each guide covers one city's licensing model and pairs it with the parent state's requirements.
New York
New York City business licenses
New York City licenses by activity through DCWP rather than a general business license; the state Certificate of Authority for sales tax is the filing nearly every seller needs.
California
Los Angeles business licenses
Los Angeles requires every business to hold a Business Tax Registration Certificate from the Office of Finance; the California seller's permit and activity permits stack on top.
Illinois
Chicago business licenses
Chicago licenses most businesses through BACP with zoning review built into the application; Illinois state registration and the IDOR sales tax account complete the stack.
Texas
Houston business licenses
Houston and Texas both lack a general business license; the real stack is the Texas sales tax permit, assumed name filings, and activity permits for regulated operations.
Arizona
Phoenix business licenses
Phoenix has no general business license; the Arizona TPT license from the state Department of Revenue is the key registration, with city regulatory licenses only for listed activities.
Pennsylvania
Philadelphia business licenses
Philadelphia requires a free Commercial Activity License tied to a BIRT tax account for every business, with L&I activity licenses and Pennsylvania state registrations stacking on top.
Washington
Seattle business licenses
Seattle licensing runs through Washington's centralized Business Licensing Service: one application covers the state license, the Seattle city certificate, and specialty endorsements.
Georgia
Atlanta business licenses
Atlanta licenses businesses through the occupational tax certificate with zoning verification and gross-receipts-based fees; Georgia's state registrations complete the stack.
Texas
San Antonio business licenses
San Antonio and Texas both lack a general business license; the stack is the Texas sales tax permit, assumed name filings, and activity permits for regulated operations.
California
San Diego business licenses
San Diego requires every business to hold a Business Tax Certificate from the City Treasurer; the California seller's permit and activity permits stack on top.
Texas
Dallas business licenses
Dallas and Texas both lack a general business license; the practical stack is the certificate of occupancy for premises, the Texas sales tax permit, and activity licenses.
Colorado
Denver business licenses
Denver has no general business license; Excise and Licenses covers listed activities, and the city's home-rule sales tax license is the registration most retailers need.
Florida
Miami business licenses
Miami businesses hold both a City of Miami Business Tax Receipt with a Certificate of Use and a separate Miami-Dade County receipt; Florida's state registrations stack on top.
Frequently asked questions
Is a city business license the same as a state business license?
No. They are separate layers issued by separate governments. Some states have a general state license or registration and most cities have their own requirement; a business inside city limits typically needs both layers, and neither substitutes for the other.
Do online businesses need a city business license?
Usually the city where the business physically operates, including a home office, is the city whose rules apply. Selling online into a city from elsewhere generally does not trigger its license, though it can trigger state-level sales tax registration.
Can Cornerstone file my city business license for me?
City licenses and tax certificates are issued by the city to the operator, and most are filed directly online in minutes. We tell you which one your market requires and handle the state licensing stack above it, which is where multi-state complexity actually lives.
