City business license guide
Last updated: April 30, 2026
Starting or running a business in Philadelphia can involve more than one filing. The main city license is called a Commercial Activity License. You may also need a Philadelphia tax account, zoning approval, a certificate of occupancy, a state tax account, a state filing, or a special permit for your line of work.
This guide explains the city, county, state, and federal layers in plain English.
Bottom line
Most businesses that operate in Philadelphia need a Commercial Activity License from the Department of Licenses and Inspections. Before you can get it, you normally need a Philadelphia Tax Identification Number through the city tax account process.
The Commercial Activity License has no city license fee, but that does not mean opening a business is free. Business taxes, zoning permits, certificates, food licenses, vending licenses, sign permits, construction permits, state tax accounts, and professional licenses can still cost money or take extra steps.
Quick start for Philadelphia business owners
- Choose your business structure and name. If you are forming an LLC, corporation, or other entity, start with Pennsylvania business registration before you use the same name with the city.
- Get an EIN from the IRS if your business structure or hiring plan needs one. The IRS says its online EIN tool is free.
- Open or update your Philadelphia tax account through the Philadelphia Tax Center. This gives you the city tax ID used for city business taxes and the Commercial Activity License.
- Apply for the Commercial Activity License through eCLIPSE or through the city tax account paper process if you cannot apply online.
- Check zoning before you sign a lease, open to customers, work from home, place signs, serve food, sell from a truck, or change how a property is used.
- Check state and federal rules for your activity. Sales, food, contractors, alcohol, tobacco, child care, health, beauty, transportation, and regulated work can add more steps.
A good first check is the city’s register a business page. It lays out the city order: structure, EIN if needed, city tax account, and Commercial Activity License.

|---|---|
| Main city license name | Commercial Activity License, often called a CAL |

| City tax account | Philadelphia Tax Identification Number, sometimes called PHTIN |
| City portal | Philadelphia Tax Center for tax accounts and eCLIPSE for many L&I licenses and permits |
| County layer | Philadelphia city and county functions are closely linked. Check Philadelphia city offices first, then state offices for entity, tax, and trade name filings. |
| Best first move | Confirm your business activity, address, legal name, trade name, zoning use, and tax account before applying for licenses. |
City, county, state, and federal layers
Business licensing in Philadelphia is layered. A city license, state filing, and federal EIN each do different things.
| Layer | What to check | Where to start |
|---|---|---|
| City | Commercial Activity License, city tax account, BIRT, NPT, wage tax, zoning, CO, signs, food, vending, rental, and other local permits. | Start with the city register-a-business page, the Philadelphia Tax Center, and L&I. |
| County | Philadelphia does not work like a separate county license office for most small businesses. Many local checks are handled by city departments. | Use Philadelphia city offices first. Use Pennsylvania state offices for entity and fictitious name filings. |
| State | Entity filing, fictitious name, sales and use tax, employer withholding, unemployment compensation, state professional licenses, and industry registrations. | Use the PA Business One-Stop Shop, Department of State, and myPATH. |
| Federal | EIN, federal permits for certain activities, federal tax duties, and current beneficial ownership reporting checks when applicable. | Use IRS, FinCEN, and the SBA federal permit guide. |
| Private platform | Marketplace, payment processor, delivery app, landlord, insurance, and bank rules. | Read the contract or account rules. These are not government licenses, but they can still affect your launch. |

Philadelphia Commercial Activity License
The city uses the term Commercial Activity License for the basic city license to do business in Philadelphia. L&I issues it. The city says any person or legal entity that does business in Philadelphia needs this license, including businesses located outside city limits that do business in the city.
The license ties your business activity to the legal entity and BIRT account. Your license, city tax account, entity filing, and trade name should match.
You can apply through eCLIPSE. The city says you should have the CAL before applying for many other business licenses.
Do not call every step a business license. In Philadelphia, the city license is the Commercial Activity License. The city tax account, BIRT return, zoning permit, certificate of occupancy, food license, and state tax accounts are separate items.
Philadelphia business tax accounts and local taxes
Before getting the Commercial Activity License, you usually need a Philadelphia Tax Identification Number. You can register through the Philadelphia Tax Center. The city tax account can cover several city taxes, depending on your business.
Two common city business taxes are the Business Income and Receipts Tax and the Net Profits Tax. BIRT applies to many for-profit business activities in the city. The city says a BIRT return may be required even if the business did not make a profit. The Net Profits Tax can apply to Philadelphia residents with business net profits and to nonresidents who do business in Philadelphia, depending on structure and facts.
Employers may also need to handle Wage Tax. Some businesses may need other city taxes, such as Use and Occupancy Tax, Hotel Tax, Liquor Tax, Tobacco Tax, Parking Tax, or the Philadelphia Beverage Tax. Do not assume your business has only one tax account just because the license itself has no fee.
Zoning, home businesses, certificates, and signs
Check zoning before you sign a lease, open a shop, start a home-based business, add a sign, serve customers, store goods, or change how a building is used. Philadelphia says the zoning code regulates how property is used and developed. L&I issues zoning permits and change-of-use approvals.
You can use the city’s location and zoning tool to look up zoning boundaries and property information. If you are changing a property use, the city’s change-of-use permit page is a key stop. A new retail store, restaurant, office, daycare, or studio may need zoning review even if the space looks ready.
Home-based businesses need special care. Philadelphia’s zoning code has home occupation rules, and some home activities may be limited or not allowed. Before you rely on a home address, read the city code section on home occupations and consider our plain-English home occupation permit guide.
A Certificate of Occupancy may matter if there is new construction, an addition, an alteration that affects exits or fire ratings, or a change in use or occupancy. The city says a CO is not required just because the owner, tenant, or residents changed, as long as the building use stays the same. But if you change how the space is used, check before opening.
Signs are another common trap. Philadelphia has a separate zoning permit for signs, and some permanent signs may also need a building permit. Ask before ordering a sign, because sign rules can cover size, height, lighting, location, and number of signs.
Business types that may need extra Philadelphia permits
Some businesses need more than the Commercial Activity License. L&I groups city business licenses by activity. Food, vending, auto work, child care, rental property, entertainment, dumpsters, tobacco, limited lodging, and other activities can have extra rules.
| Business type | Extra item to check | Why it matters |
|---|---|---|
| Restaurant, deli, caterer, or food prep business | Food Preparation and Serving License, public health review, zoning, and possible building or fire permits. | The city says food businesses that prepare or serve food for public consumption need this license. |
| Food truck, cart, or movable stand | Food Establishment Retail, Non-Permanent Location License, location rules, health review, and vending rules. | Mobile food businesses have city license and location rules. See our food truck permit guide. |
| Sidewalk or vehicle vending | Vending approval, special district rules, and the correct vending license. | Some vending locations need approval from the Vending Unit before the license application. |
| Retail store or office | Zoning use, certificate of occupancy if use changes, signs, city taxes, and state sales tax if selling taxable goods. | A storefront can be blocked by zoning or occupancy issues even after the city license is issued. |
| Online seller based in Philadelphia | City CAL, city taxes, Pennsylvania sales tax account if selling taxable goods, and platform rules. | Online sellers may still have local and state duties. See online business license rules. |
| Freelancer or consultant | CAL, city tax account, NPT/BIRT checks, home occupation rules if working from home, and professional licenses if regulated. | A service business can still be a city business even without a storefront. |
Food businesses should start with the city’s Food Preparation and Serving License page or the mobile food license page, depending on the setup. Vending businesses should also check the city page for special vending districts.
Pennsylvania state steps for Philadelphia businesses
The city license does not form an LLC or corporation. If you want a Pennsylvania LLC, corporation, nonprofit, or other entity, use the Pennsylvania Department of State. The state’s register a business page points business owners to Business Filing Services for entity filings and related forms.
If you use a business name that is not your real or proper legal name, Pennsylvania may require a fictitious name filing. The Department of State says fictitious names are registered at the state level, not at the county seat. Read the state’s fictitious names page before you put a DBA on signs, invoices, licenses, bank accounts, or tax records.
State tax accounts are separate from city tax accounts. If you sell taxable goods, rent rooms, hire employees, withhold wages, need unemployment compensation, or have another state tax duty, use Pennsylvania’s Register My Business for Taxes page and myPATH. The PA Business One-Stop Shop can also help you sort state registration steps.
Federal steps to check
Many businesses need an EIN. The IRS says you can use its EIN tool for free if you qualify. The IRS warns that you never have to pay a fee for an EIN when you get it directly from the IRS.
Some activities can also need federal permits. The SBA’s license and permit guide points to federal agencies for activities such as alcohol, agriculture, aviation, firearms, broadcasting, transportation, and other regulated fields.
Beneficial ownership reporting has changed. FinCEN says, as of its March 26, 2025 alert, entities created in the United States and their beneficial owners are exempt from BOI reporting to FinCEN, while certain foreign entities registered to do business in the United States may still have deadlines. Check the current FinCEN BOI page before relying on old advice or paid mailers.
Costs you can plan for
Philadelphia says there is no cost for the Commercial Activity License. Still, your full startup cost depends on your business activity, location, entity choice, taxes, property work, and permits. Do not use the free CAL as your total budget.
| Cost area | What to expect | Where to verify |
|---|---|---|
| Commercial Activity License | The city lists no cost for this license. | Verify on the city CAL page before applying. |
| City business taxes | BIRT, NPT, Wage Tax, and other taxes may apply based on activity and structure. | Use the Philadelphia Tax Center and city tax pages. |
| Zoning or CO | Permit and certificate fees can apply when use, occupancy, construction, or signs are involved. | Use L&I fee pages and the exact permit page. |
| Food or vending | License fees, renewals, inspections, plan review, and location approvals may apply. | Use the specific food or vending license page. |
| State filings | Entity, fictitious name, state tax, and professional filings may have fees. | Use PA Department of State, myPATH, and the relevant board. |
| Federal steps | An IRS EIN is free through the IRS. Federal permits may have separate fees. | Use IRS and the proper federal agency. |
What does this mean for me?
If you are opening a simple service business, your first city steps are usually the Philadelphia tax account and Commercial Activity License. But your location and activity can add more. A home-based consultant may need to check home occupation rules. A retail shop may need zoning and state sales tax. A restaurant may need public health review, food licensing, zoning, inspections, and possibly construction permits.
The safest order is: name and structure, federal EIN if needed, state filing if needed, city tax account, city Commercial Activity License, zoning and occupancy checks, then activity-specific permits. If you already started out of order, do not panic. Gather your exact business name, address, activity, and tax account details, then ask the right office what needs to be corrected.
Real-world examples
Example 1: Home-based web designer
A web designer working from a Philadelphia apartment may still need a city tax account, CAL, home occupation check, and city tax filings.
Example 2: Small sandwich shop
A sandwich shop should check zoning, CO, food licensing, public health review, signs, city taxes, state sales tax, and any buildout permits.
Example 3: Weekend street vendor
A vendor should confirm allowed locations before buying equipment. Selling food adds mobile food and public health checks.
Common mistakes to avoid
- Getting an LLC and thinking that means you have a Philadelphia business license.
- Getting the Commercial Activity License but ignoring BIRT, NPT, Wage Tax, or other city tax filing duties.
- Signing a lease before confirming zoning use and certificate of occupancy needs.
- Using a DBA on signs or bank records without checking state fictitious name rules and city tax account records.
- Opening a food, vending, child care, rental, or regulated business with only the basic city license.
- Assuming an online or home-based business has no local license or tax duties.
- Paying a private site for an EIN when the IRS issues EINs for free through its own tool.
Phone and email scripts
Before contacting an agency, have your legal name, trade name, address, and business activity ready.
City license script
Hello, I am starting a [business type] in Philadelphia at [address or general area]. I want to confirm whether I need a Commercial Activity License, an Activity License Number, or any other L&I business license before I start. My legal name is [legal name], and my trade name is [trade name]. What should I check next?
City tax account script
Hello, I need to open or update a Philadelphia tax account for a [business type]. I may have [sales, employees, net profits, rental activity, or other activity]. Which city tax accounts should I add, and how should my trade name appear so it matches my Commercial Activity License?
Zoning or CO script
Hello, I am planning to use [address] for [business activity]. The space was last used as [prior use, if known]. Do I need a zoning permit, change-of-use approval, certificate of occupancy, building permit, or sign permit before opening?
Food or vending script
Hello, I want to operate a [food truck, cart, market stand, restaurant, caterer, or vendor business] in Philadelphia. Where can I confirm the correct food license, vending approval, health review, location approval, and renewal steps for my setup?
What to do if this doesn’t work
If an online portal does not accept your application, do not guess. Save screenshots, write down the date, and check whether your legal name, tax ID, trade name, address, and entity type match across systems. A mismatch between the Pennsylvania entity record, Philadelphia tax account, and CAL application can cause problems.
If you are unsure which office handles the issue, start with the most direct office: Revenue for city tax accounts, L&I for city licenses and permits, the Vending Unit for special vending location approval, the Department of State for entity and fictitious name filings, and myPATH for Pennsylvania tax accounts.
