Pennsylvania has one of the higher corporate net income tax rates in the country at 8.99% for 2024, though it is scheduled to phase down toward 4.99% over the coming years. The personal income tax rate is a flat 3.07%. However, Philadelphia adds significant additional tax layers. The city imposes a wage tax on all residents (3.75%) and non-residents who work in Philadelphia (3.44%). Philadelphia also has a Business Income and Receipts Tax (BIRT) on both gross receipts and net income for businesses operating within city limits. The NPT (Net Profits Tax) applies to self-employed individuals and unincorporated businesses.
Philadelphia’s layered tax system is one of the most complex of any major US city. The city’s wage tax applies to remote workers who are Philadelphia residents even when working from home, creating significant questions for businesses with employees across different locations. The BIRT applies to almost all Philadelphia-based business activity and requires separate registration and annual filing with the city. Many new business owners underestimate their total effective tax rate when they fail to account for city-level taxes on top of state obligations. The education and healthcare sectors, which are major Philadelphia employers, also create specific compliance questions around nonprofit status and commercially taxable activities.
TurboTax Business handles federal and Pennsylvania state returns, but it does not fully address Philadelphia’s city-level BIRT, NPT, and wage tax obligations. QuickBooks can assist with bookkeeping but Philadelphia’s city tax filings typically require local expertise.
Many Philadelphia business owners attempt DIY returns for their first year, then quickly discover that city-level BIRT and NPT filings require local CPA expertise that general tax software does not adequately address.
Philadelphia CPAs serve businesses across the greater Philadelphia metro including Philadelphia, Delaware, Montgomery, Bucks, Chester, and Camden (NJ) counties.

The BIRT is a Philadelphia city tax imposed on businesses operating within city limits. It has two components: a gross receipts portion (0.1415% for most businesses) and a net income portion (6.25%). Nearly all businesses with taxable activity in Philadelphia must file a BIRT return, even if they also pay Pennsylvania corporate net income tax. There is a small business exemption for businesses with under $100,000 in gross receipts. A Philadelphia CPA can ensure you are registered correctly and taking advantage of any available exemptions.
Philadelphia’s wage tax applies to all wages earned within city limits. For residents, the rate is 3.75% on all wages regardless of where they work. For non-residents working in Philadelphia, the rate is 3.44%. Employers must withhold wage tax from employee paychecks and remit to the city. The wage tax is a significant cost consideration for Philadelphia-based businesses and can affect compensation planning and hiring decisions.
Philadelphia business owners must make federal and Pennsylvania state quarterly estimated tax payments on the standard schedule. For city taxes, the BIRT requires quarterly payments if annual liability exceeds a certain threshold. The wage tax is paid on a quarterly or monthly basis depending on the amount withheld. Keeping track of all filing deadlines across federal, state, and city levels is a common challenge for Philadelphia small business owners and a key reason to work with a local CPA.
Yes. Pennsylvania has been phasing down its corporate net income tax rate from 9.99%. The rate was 8.99% in 2024 and is scheduled to decrease by 0.5% per year until it reaches 4.99%. This phased reduction creates planning opportunities for Philadelphia businesses, particularly those structured as C corporations. A CPA can help you time income and deductions strategically around the rate reductions.
Philadelphia business owners benefit from federal deductions including Section 179 expensing, home office deductions (for those working outside the city), and standard business expense deductions. At the Pennsylvania level, the state conforms to most federal deductions. For the BIRT, allowable deductions reduce the net income portion of the tax. Philadelphia also offers wage tax refunds for residents who paid wage tax to another jurisdiction on the same income. A local CPA can identify which deductions apply to your specific business and structure.
