City business license guide
Last updated: October 5, 2026
Starting or running a business in Philadelphia can involve more than one filing. The city’s basic business license is the Commercial Activity License, but you may also need city tax accounts, zoning or occupancy approval, state tax registration, or a special permit for your activity.
This guide separates the city, county, state, and federal layers in plain English.
Bottom line
Most people and legal entities doing business in Philadelphia need a Commercial Activity License, or CAL, from the Department of Licenses and Inspections. This can include businesses based outside the city that do business inside Philadelphia.
The CAL is free and does not need renewal. You normally need Philadelphia tax-account information first. Some activities use an Activity License Number instead, so check the official CAL page if your activity is listed as an exception.
Philadelphia business changes and clarifications, April 1–October 1, 2026
- April 29 clarification: Philadelphia Revenue explained that the PHTIN is a master taxpayer identifier, while individual taxes such as BIRT have separate account numbers. This clarified the system; it did not create a new license.
- July 1 change: Wage Tax rates fell to 3.735% for Philadelphia residents and 3.425% for nonresidents.
- 2026 tax-year change: BIRT rates are 1.395 mills on gross receipts and 5.65% on taxable net income for tax year 2026, filed in 2027. The 2026 NPT rates are 3.735% for residents and 3.425% for nonresidents.
- August 14 federal change: FinCEN’s final BOI rule made the exemption permanent for U.S.-created companies. Certain foreign-created entities registered in the U.S. can still have BOI duties.
- Rechecked existing rule: The former $100,000 BIRT exemption had already ended for tax year 2025. Do not treat that as a new October change or rely on the old threshold.
Quick start for Philadelphia business owners
- Write down your exact legal name, trade name, business activity, and street address.
- Choose your structure and complete any Pennsylvania entity filing.
- Get an EIN from the IRS if needed.
- Open or update your Philadelphia tax account through the Philadelphia Tax Center.
- Apply for the CAL through eCLIPSE if the CAL applies to your activity.
- Check zoning and occupancy before signing a lease, opening to customers, changing a property use, working from home, or installing signs.
- Check Pennsylvania and federal rules for sales tax, employees, professional licensing, and regulated activities.
Philadelphia’s Register a business page is a useful starting point for the city tax-account and CAL steps.
Philadelphia business license facts box
| City | Philadelphia, Pennsylvania |
|---|---|
| Main city license | Commercial Activity License, or CAL |
| City office | Philadelphia Department of Licenses and Inspections, or L&I |
| City tax identifier | Philadelphia Tax Identification Number, or PHTIN, plus separate tax-account numbers |
| City portals | Philadelphia Tax Center for taxes; eCLIPSE for many L&I licenses and permits |
| CAL fee and renewal | No fee; no renewal |
| County layer | Philadelphia city and county are coterminous, so most local licensing and permit questions are handled by City agencies rather than a separate county license office. |
| Best first move | Confirm the activity, exact address, legal entity, trade name, tax setup, and allowed property use. |
City, county, state, and federal layers
Philadelphia licensing is layered. A CAL, state entity filing, tax account, zoning approval, and federal EIN each do different jobs.
| Layer | What to check | Where to start |
|---|---|---|
| City | CAL or Activity License Number, city taxes, zoning, occupancy, signs, food, vending, rental, and other activity licenses. | Philadelphia Tax Center and L&I/eCLIPSE. |
| County | No separate county business-license system for most Philadelphia small businesses. | Use City agencies unless an official page directs you elsewhere. |
| State | Entity filing, fictitious name, sales tax, employer accounts, annual reports, and professional or industry licenses. | Department of State, Business One-Stop Shop, and myPATH. |
| Federal | EIN and federal permits for regulated activities. | IRS and the relevant federal agency. |
| Private rules | Landlord, HOA, insurer, bank, marketplace, and platform conditions. | Private approval does not replace government approval. |
For the state layer, see our Pennsylvania business license guide. For basic terms, see business license vs LLC vs DBA vs seller’s permit.
Philadelphia Commercial Activity License
The CAL is Philadelphia’s basic license to do business. L&I issues it, and the city says the requirement can apply even when the business is located outside city limits but does business in Philadelphia.
The application must identify the legal entity as it appears on the Philadelphia tax account. Any DBA or trade name should also be listed on that account. You can apply through eCLIPSE. The city says the online CAL is issued automatically, costs nothing, and does not need renewal.
Some activities use an Activity License Number instead of a CAL, including certain owner-occupied small rentals, nonprofits, and vacant-property licensing. Confirm the correct path on the official CAL page.
Do not call every step a business license. A PHTIN, BIRT account, tax return, zoning permit, Certificate of Occupancy, food license, state sales-tax license, and professional license are separate items.
Philadelphia business tax accounts and local taxes
Register through the Philadelphia Tax Center. Philadelphia Revenue describes the PHTIN as the master taxpayer identifier, while taxes such as BIRT have separate account numbers.
The Business Income and Receipts Tax applies broadly to Philadelphia business activity. The old statutory exemption for the first $100,000 of Philadelphia gross receipts ended for tax year 2025. Small businesses should not assume the former threshold still removes the filing duty. For tax year 2026, filed in 2027, the city lists BIRT rates of 1.395 mills on gross receipts and 5.65% on taxable net income.
The Net Profits Tax can apply to individuals, partnerships, associations, LLCs, estates, and trusts. For tax year 2026, the rates are 3.735% for residents and 3.425% for nonresidents. Employers should also review Wage Tax; the same resident and nonresident rates took effect July 1, 2026.
Use and Occupancy Tax can apply when Philadelphia property is used for business, including some home businesses. The former $2,000 annual U&O exemption ended beginning in 2026. Other city taxes can apply depending on activity, such as Hotel, Liquor, Tobacco, Parking, or Philadelphia Beverage Tax.
Zoning, home businesses, certificates, and signs
Check zoning before signing a lease, changing a property use, opening to customers, working from home, adding signs, or starting a buildout. Use the city’s location and zoning information tools for the exact property. A mailing-city label alone is not a zoning check.
If your planned activity is a different use, review the change-of-use zoning permit process. A Certificate of Occupancy is required for new construction, additions, certain alterations, and changes in use or occupancy. A CO is not required merely because the owner or tenant changed while the building use stayed the same.
Home-based businesses
Philadelphia recognizes home office, professional home business, and general home business categories. The rules change with the zoning district and with customer or employee visits. Home occupations must remain secondary to residential use and cannot create unreasonable noise, odors, traffic, loading, or similar neighborhood effects. Read the city code on home occupations and our home occupation permit guide.
Signs
Philadelphia separately regulates signs. Zoning approval is generally required, with listed exceptions for some small window, interior, directional, and temporary signs. Many permanent signs also need a building permit. Check the sign zoning permit page before ordering a sign.
Business types that may need extra Philadelphia permits
The CAL is only the starting point for many activities. Philadelphia has separate requirements for food, vending, automotive work, child care, rentals, entertainment, tobacco, lodging, construction trades, and other regulated work.
| Business type | Extra items to check | Why it matters |
|---|---|---|
| Restaurant, deli, café, or caterer | Food license, Health Department review, zoning, occupancy, and possible building/fire approvals. | The exact food license depends on the operation. |
| Food truck, cart, or mobile stand | Non-permanent food license, public-health approval, vending license, and location rules. | Location approval can be as important as the food license. See our food truck permit guide. |
| Sidewalk or vehicle vendor | Correct vending license and restricted-street or special-district rules. | Some districts use extra approvals or licenses. |
| Retail store or office | Zoning, CO if required, signs, city taxes, and Pennsylvania sales-tax registration when applicable. | A CAL does not prove the storefront use is allowed. |
| Online seller or freelancer | CAL, city taxes, home-occupation rules, and state tax or professional registration when required. | No storefront does not mean no local duties. |
Food businesses should start with the city’s Food Preparation and Serving License page or the non-permanent food license page. Vendors should also check special vending district rules.
Pennsylvania state steps for Philadelphia businesses
The CAL does not form an LLC or corporation. Use the Department of State’s Register a Business service for Pennsylvania entity filings.
If you use a name other than your real or proper legal name, Pennsylvania may require a fictitious-name registration. The state says these filings are made with the Department of State, not at the county seat. Review the Fictitious Names page before using a DBA across city licenses and tax records.
State tax registration is separate. Use myPATH business tax registration for sales and use tax, employer withholding, unemployment compensation, and other applicable accounts. Pennsylvania’s base sales tax is 6%, with an additional 2% local sales and use tax in Philadelphia for a combined 8% where the tax applies.
Pennsylvania filing entities also have annual-report duties. The state lists June 30 for corporations, September 30 for LLCs, and December 31 for several other association types. A Pennsylvania LLC’s 2026 annual-report window ended September 30, so check the entity record if you have not filed.
Federal steps to check
An EIN is a federal tax ID. The IRS says many employers, corporations, partnerships, and other businesses need one. You can get an EIN directly from the IRS for free. Some federally regulated activities also need federal permits from the responsible agency.
Beneficial ownership reporting changed again in 2026. FinCEN says its final rule, effective August 14, 2026, makes U.S.-created companies exempt from BOI reporting. Certain foreign-created entities registered to do business in the U.S. can still be reporting companies.
Costs you can plan for
The CAL is free, but your real startup cost can include taxes, special licenses, zoning, plan review, inspections, signs, and construction.
| Cost area | Current example | What to remember |
|---|---|---|
| Commercial Activity License | $0; no renewal. | Tax setup still comes first. |
| Food preparation/serving license | $299 for a small establishment, $415 for 30 or more seats, or $275 for a catering company. | Plan review or construction can add separate costs. |
| Non-permanent food retail license | $179; renewal $179. | Mobile food can also need vending approval. |
| Sidewalk sales license | $330 per location; renewal $330. | Restricted streets and special districts still matter. |
| Zoning, CO, signs, construction | Varies by permit and project. | Verify the exact L&I page before budgeting. |
Application fees, license fees, renewal fees, inspection charges, and construction permits are different costs. Verify the fee for the exact approval you need.
What does this mean for me?
A simple service business may start with the Philadelphia tax account and CAL. A home-based business adds home-occupation checks. A storefront adds zoning and occupancy. A restaurant adds health and food licensing.
For a property-based business, check zoning before an expensive lease, buildout, sign, vehicle, or food-equipment purchase. A quick, free CAL does not mean the location is ready to open.
Real-world examples
Example 1: Home-based web designer
A web designer working alone from a Philadelphia apartment may need a city tax account, CAL, BIRT/NPT filings as applicable, and a home-occupation check.
Example 2: Small sandwich shop
A sandwich shop should check zoning, CO status, health review, food licensing, signs, city taxes, state sales tax, and any buildout permits.
Example 3: Weekend street vendor
A vendor should confirm allowed locations before buying a cart or vehicle. Food adds public-health and mobile-food licensing.
Example 4: Consultant based outside Philadelphia
An outside-city office does not automatically remove Philadelphia duties. The city says the CAL can apply when the business does work in Philadelphia.
Common mistakes to avoid
- Forming an LLC and thinking that is the Philadelphia business license.
- Relying on the old $100,000 BIRT exemption.
- Getting a CAL but ignoring other city taxes.
- Signing a lease before checking zoning and occupancy.
- Using a trade name that does not match tax and license records.
- Opening a food, vending, rental, child-care, or other regulated business with only the CAL.
- Assuming a home-based or online business has no local duties.
- Assuming a mailing address alone proves the correct jurisdiction.
- Paying a private website for an EIN when the IRS issues it free.

What to do if this doesn’t work
If eCLIPSE or the Tax Center rejects your application, save the error and compare the legal name, DBA, EIN or SSN, PHTIN, tax-account number, entity type, and address across your records.
Use Revenue for city tax accounts; L&I for licenses, zoning, permits, and occupancy; Public Health for food review; the Pennsylvania Department of State for entity and fictitious-name filings; and myPATH for state tax accounts.

FAQ
Does Philadelphia require a general business license?
Philadelphia uses a Commercial Activity License for most people and legal entities doing business in the city. L&I issues it, and you need city tax-account information first. Some activities use an Activity License Number instead, so check the official CAL page for exceptions.
Is the Philadelphia Commercial Activity License free?
Yes. Philadelphia lists no fee for the Commercial Activity License, and the CAL does not need to be renewed. Other costs can still apply for taxes, zoning, occupancy, food or vending licenses, signs, construction, state filings, and professional or industry permits.
Do I need a Philadelphia license if my business is outside the city?
You may. Philadelphia says the Commercial Activity License requirement includes businesses located outside city limits that do business in Philadelphia. Confirm the exact activity and tax treatment with the city.
Does forming an LLC replace the Philadelphia business license?
No. An LLC is a state business structure. The Philadelphia Commercial Activity License, city tax accounts, zoning approvals, occupancy requirements, and activity-specific permits are separate checks.
Do home-based businesses in Philadelphia need to check zoning?
Yes. Philadelphia has specific home-occupation categories and standards. Whether customers or employees come to the home, the zoning district, the type of work, deliveries, noise, storage, and other neighborhood impacts can affect what is allowed.
Where should I start if I am opening a food business?
Start with the city tax account and Commercial Activity License, then confirm the property use, Certificate of Occupancy needs, Department of Public Health plan-review or eligibility steps, and the correct food license for a permanent location, mobile setup, or catering business.
