Accounting & Tax Services in Pennsylvania

Pennsylvania’s $800+ billion GDP makes it the 5th largest state economy in the nation, home to 23+ Fortune 500 companies split between Philadelphia and Pittsburgh. The Commonwealth’s healthcare sector is anchored by systems like UPMC with 92,000 employees and Penn Medicine, while pharmaceutical leaders including Merck employ thousands at facilities like the West Point campus. Pittsburgh has transformed into a robotics and AI hub, attracting R&D centers from Apple, Google, and Bosch.

Pennsylvania’s tax landscape requires careful planning. The state levies a flat 8.99% corporate net income tax, one of the highest in the country, alongside local earned income taxes that vary by municipality. Philadelphia adds its own Business Income and Receipts Tax (BIRT) and wage tax. S-Corp owners operating across the Lehigh Valley logistics corridor or the I-76 manufacturing belt face nexus considerations when selling into neighboring states like New Jersey, New York, and Delaware.

SDO CPA works with Pennsylvania business owners across healthcare, life sciences, manufacturing, and technology to structure entities, optimize S-Corp reasonable compensation, and manage the interplay between federal obligations and Pennsylvania’s layered state and local tax system. Whether you’re running a biotech startup in University City or a manufacturing operation in the Lehigh Valley, 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. Additionally, Philadelphia businesses must account for BIRT (gross receipts and net income tax) and the city wage tax, which adds another layer that proper planning can minimize.

Pennsylvania is home to 1,100,000+ small businesses and a population of 13,002,700. From Healthcare, Manufacturing, Technology to professional services, Pennsylvania business owners need CPAs who understand layered state and local tax obligations including corporate net income tax, local earned income taxes, and city-specific levies and can provide year-round tax planning — not just compliance.
