How Your Pennsylvania Paycheck Is Calculated
Pennsylvania levies a flat 3.07% state income tax rate on personal income under 72 P.S. ยง 7302, according to the Pennsylvania Department of Revenue (PA DOR). Pennsylvania's 3.07% flat rate is tied with Indiana as one of the lowest statutory flat state income tax rates in the nation.
Important PA Tax Rule: 401(k) Contributions Are NOT Pre-Tax for State Tax
Unlike federal tax law and almost every other state, Pennsylvania does NOT allow pre-tax deductions for 401(k) or 403(b) retirement contributions for state income tax purposes (72 P.S. ยง 7301). W-2 401(k) contributions are taxable for PA 3.07% state tax and local EIT, even though they reduce your federal taxable income! However, Section 125 health insurance premiums and HSA/FSA contributions ARE pre-tax for PA state and local taxes.
Pennsylvania Local Earned Income Tax (EIT) & Philadelphia Wage Tax
In addition to the 3.07% state tax, Pennsylvania municipalities and school districts levy local Earned Income Taxes (EIT) and Local Services Taxes (LST):
- Philadelphia Wage Tax โ 3.75% resident tax rate / 3.44% non-resident rate under the Sterling Act.
- City of Pittsburgh โ 3.00% local EIT (1.0% city + 2.0% school district).
- Scranton โ 3.40% local EIT.
- Act 511 Municipalities โ Most PA townships, boroughs, and school districts levy 1.00% to 2.50% local EIT.
- Local Services Tax (LST) โ Typically $52 per year ($1 per week) deducted by payroll for emergency municipal services.

How Much of Your Pennsylvania Salary Do You Actually Keep?
Most Pennsylvania workers take home 70โ77% of their gross salary, depending on local EIT obligations (Philadelphia residents keep ~70โ72% due to combined 3.07% PA state + 3.75% Philly wage tax). For workers in Philadelphia Metro (finance, healthcare Penn Medicine/Jefferson, Comcast HQ, pharma), Pittsburgh Metro (robotics/tech, UPMC healthcare, steel & advanced manufacturing, PNC Bank), Lehigh Valley (logistics & manufacturing), and Harrisburg (state capital & Hershey food processing), PA's low 3.07% state tax rate keeps overall tax rates reasonable.
