Accounting & Tax Services in Philadelphia, PA
Philadelphia is the birthplace of American business and today anchors one of the nation’s largest metro economies with a $557 billion gross metropolitan product. The city’s “eds and meds” sector drives employment, with Penn Medicine, Jefferson Health, and Comcast among the largest employers. University City has emerged as a thriving biotech and startup hub, where Drexel and the University of Pennsylvania fuel innovation in life sciences and technology.
Philadelphia’s tax structure is uniquely complex. The Business Income and Receipts Tax (BIRT) applies to gross receipts and net income for all businesses operating in the city. The Philadelphia wage tax adds another layer for both residents and non-residents working in the city. Combined with Pennsylvania’s flat 3.07% personal income tax and 8.99% corporate net income tax, business owners face four or more tax jurisdictions simultaneously. S-Corp owners in Center City, University City, and the Navy Yard corridor need careful entity structuring to minimize this cumulative burden.
SDO CPA works with Philadelphia business owners across healthcare, life sciences, professional services, and technology to optimize entity structure, claim R&D tax credits, and manage the interplay between BIRT, wage tax, state, and federal obligations. For biotech startups managing SBIR/STTR grants or established practices affiliated with major health systems, we provide monthly bookkeeping and fractional CFO services scaled to your stage of growth.
Pennsylvania Tax Planning Tip
Pennsylvania’s flat 8.99% corporate net income tax is among the highest in the U.S., but pass-through entities like S-Corps and partnerships are taxed at the individual level at a flat 3.07% personal income tax rate. Choosing the right entity structure can significantly reduce your state tax burden. Philadelphia businesses must also account for BIRT and the city wage tax, which adds another layer that proper planning can minimize.
