Pennsylvania State Income Tax Guide (2026)

Pennsylvania's 3.07% flat rate has held since 2004 — predictable, mid-priced for a state with full retirement exemption, and among the lowest flat-rate structures in the country. The math is genuinely simple: take your compensation, multiply by 0.0307, that's your PA state tax. No brackets, no standard deduction, no personal exemption, no income-tested phase-outs.

The structural quirk is the part movers from New Jersey or New York don't see coming. PA taxes 'compensation' — your gross wages before federal AGI adjustments. That means 401(k) contributions, traditional IRA contributions, and most pre-tax payroll deductions reduce your federal taxable income but NOT your PA taxable income. A $100,000 PA wage earner contributing $20,000 to a 401(k) pays federal tax on $80,000 (after the federal SD) but PA tax on the full $100,000. The PA bill: $3,070. The bill in a conforming state at the same comp: ~$2,455. About $615/year of 'hidden' PA tax during working years.

It doesn't change the recommendation to max the 401(k) — the federal benefit (~$5,400 at 22% federal rate) dominates the PA non-conformity cost (~$615). But it does mean PA workers should run combined federal-plus-state math when deciding between 401(k) and Roth 401(k) contributions, especially in the higher federal brackets. The PA-tax-already-paid contributions effectively become basis at retirement — see the retirement FAQ for why this matters.

Local Earned Income Tax (EIT) compounds the state rate for most PA workers. Most municipalities outside Philadelphia levy 1-2% under Act 32 (combined municipal + school district rate). Pittsburgh and most of Allegheny County combined ~3.0%. Lower Merion (Main Line), Radnor, Bryn Mawr suburbs 1.0-1.5%. Lehigh Valley townships 1.0-1.75%. State College (Penn State) ~1.5%. Erie ~1.65%. Always look up your specific address — adjacent townships sometimes differ by 50-100 basis points.

Philadelphia operates under a separate legal framework (the Sterling Act, predating Act 32) and levies the highest big-city local wage tax in the country. Residents pay 3.75% on all earned income regardless of where they work. Non-residents working in Philadelphia (commuting from NJ, the suburbs, or anywhere else) pay 3.44% on wages earned for work performed within city limits. The tax is withheld by employers and remitted to the City; there is no separate filing for most W-2 workers. The City also operates a Business Income & Receipts Tax (BIRT) for self-employed and pass-through income — different mechanics but real for Philly-based freelancers.

The non-resident rate matters more than it looks. A Cherry Hill NJ resident working downtown pays 3.44% Philly wage tax (no PA state, no NJ state per reciprocity — but Philly stacks anyway). A Bryn Mawr hybrid worker splitting downtown/home pays 3.44% only on Philly-workday wages. Track your work location — the City has been increasingly aggressive about auditing hybrid workers since 2022.

Pennsylvania has wage-tax reciprocity with six states — NJ, OH, IN, MD, VA, and WV. The biggest cross-border flow is the PA-NJ Delaware Valley commute (Philadelphia metro extending into Camden, Burlington, and Gloucester counties). NJ residents working in PA file NJ Form NJ-165 with their PA employer; PA tax withholds, NJ collects nothing on those wages. The reverse works for PA residents commuting to NJ employers (file PA REV-419 with the NJ employer). The reciprocity zeros out the state-level double-tax. Philadelphia's wage tax operates outside reciprocity and still applies to anyone working in Philly.

Pittsburgh-to-Ohio, PA-WV (Wheeling / Morgantown), and PA-MD (Mason-Dixon line) cross-border setups work the same way under their respective reciprocity agreements. One of the cleanest interstate commute setups in the country alongside the MD-DC-VA Capital region.

Four scenarios that cover most readers. Find the one closest to you. If none match, the calculator at the top is for you.

Pennsylvania property tax statewide average is about 1.5% effective on market value — above the national average but well below New Jersey. The structural reason is that PA schools rely heavily on local property tax for funding (one of the highest local-school-funding shares in the country), so tax bills correlate strongly with school district quality.

Approximate effective rates by area on a primary residence: Philadelphia ~0.95% (lower than peer cities because of the wage tax doing the work), Pittsburgh (Allegheny County) 1.85-2.05% (high due to Pittsburgh Public Schools mechanics and the city's narrow grand list), Bucks / Montgomery / Chester (Philly suburbs and Main Line) 1.4-2.0%, Lehigh Valley (Allentown / Bethlehem / Easton) 1.7-2.2%, Erie 1.6-1.8%, central PA rural townships 1.0-1.5%, State College area 1.4-1.7%.

The Main Line is the famous outlier: Lower Merion Township, Radnor, Tredyffrin-Easttown school districts run effective rates 1.4-2.0% but on home values that often exceed $700K, making the absolute dollars steep but the school quality genuinely exceptional. The Main Line property tax bill is the lifestyle premium being collected in a different form than NJ's or Westchester's — same trade, different invoice.

On top of the annual mill, PA levies a real estate transfer tax of 1% at the state level plus 1% by most municipalities = 2% combined on sales (Philadelphia is higher at 4.278% combined city + state). The OBBBA SALT cap raise to $25K softens the deductibility hit on the annual property tax bill but doesn't change the cash bill.

If you're earning $100K+ in PA and you're not doing most of these, you may be leaving real money on the table. None of this is exotic. Most of it is 30 minutes of setup once a year and discipline the rest of the year.

Pennsylvania is appreciably better than its dense-urban tax reputation for almost all working professionals. The 3.07% flat state rate is genuinely competitive (stable since 2004 — the kind of predictability tax planners actually value), retirement income is fully exempt (best-in-class for retirees), and six-state reciprocity keeps interstate work clean. The two real catches are the 401(k) non-conformity (a small annual cost during working years that converts to back-end benefit at retirement) and Philadelphia's wage tax (which compounds the effective rate for Philly residents specifically).

Run your numbers in the calculator above. The PA line on the calculator already applies PA's no-standard-deduction rule (compensation taxed directly), so it should match your actual PA return closely.

Then add your local EIT manually — the calculator doesn't model municipal layers. Philadelphia residents 3.75%, Pittsburgh ~3.0%, Lower Merion / Main Line ~1.0-1.5%, Lehigh Valley 1.0-1.75%, State College ~1.5%, Erie ~1.65%. Use munstats.pa.gov for any specific address.

If you're contributing to a 401(k) and just moved to PA, don't reduce contributions over the non-conformity — federal benefits dominate the math. Max PA529 contributions if you have kids and you're in a 22%+ federal bracket. If you commute across a PA state line, file the right reciprocity certificate with your employer (NJ-165 for NJ, REV-419 incoming for PA). The biggest tax mistake most Pennsylvanians make isn't paying too much PA state tax — it's missing the local EIT calculation and being surprised at filing time, or forgetting to file a reciprocity certificate.
