Pennsylvania‘s tax system ranks 34th overall on the 2025 State Tax Competitiveness Index. Pennsylvania’s corporate income tax rate is unusually high but is slowly phasing down to a competitive 4.99 percent. Pennsylvania also has a low, flat state-level individual income tax rate of 3.07 percent, but local earned income taxes (on a narrower base than the state income tax) dramatically increase overall levels of income taxation in the Commonwealth.
Pennsylvania is among the very few states to significantly cap net operating loss carryforwards, limiting them to 40 percent of taxable income, but recently enacted legislation will phase this cap up to 80 percent, in 10 percentage point increments, from 2025 through 2029. The Commonwealth does not conform to the Section 168(k) first-year expensing regime offered at the federal level. Pennsylvania also allows localities with existing gross receipts taxes to retain them, though new local gross receipts taxes cannot be created.
Local governments, meanwhile, operate under a patchwork of different state-imposed tax rules, with Philadelphia possessing unique authority given to no other jurisdiction. Consequently, Pennsylvania’s local taxes are among the more complex and burdensome in the country.
From 2021-2024, within the span of 3.5 years, more states enacted laws converting graduated-rate individual income tax structures into single-rate income tax structures than did so in the whole 108-year history of state income taxation up until that point.
Thirty-nine states will begin 2025 with notable tax changes, including nine states cutting individual income taxes. Recent years have seen a wave of significant tax reforms, and the changes scheduled for 2025 show that these efforts have not let up.
