FAQ

Frequently Asked Questions

How does Pennsylvania's flat tax compare to Washington State?

Pennsylvania charges a flat 3.07% on all income with no deductions or exemptions from the rate. On $100,000: $3,070/year in PA state tax vs $0 in Washington State. Over 10 years: $30,700 savings from Washington State. Philadelphia residents add a 3.79% city wage tax, totaling $6,860 on $100k income. Pennsylvania does exempt most retirement income (Social Security, pensions, IRAs after 59½), so PA can be competitive for retirees.

Is Philadelphia really that expensive to live in taxwise?

Philadelphia has one of the highest combined income tax burdens of any major US city: 3.07% state + 3.79% city wage tax = 6.86% combined on resident income. On $100k: $6,860/year. Washington State: $0/year. The city wage tax was established in 1939 and has proven extremely difficult to reduce politically. Philadelphia also has a school district income tax and various other levies. For high earners who must live in Philadelphia, the tax burden is substantial.

Is Pittsburgh different from Philadelphia for taxes?

Yes — Pittsburgh's local income tax situation is much better than Philadelphia's. Pittsburgh residents pay the state 3.07% plus a 3% earned income tax (local), totaling ~6.07% combined — still high vs Washington State's 0%, but better than Philadelphia's 6.86%. Pittsburgh also has lower housing costs (~$220k median vs Philadelphia suburbs ~$380k) and has undergone significant economic revitalization as a tech and healthcare hub (Carnegie Mellon, University of Pittsburgh driving AI research).

Does Pennsylvania exempt retirement income from tax?

Pennsylvania is relatively generous with retirement income exclusions: it exempts Social Security benefits, most private pensions and employer retirement plans, and IRA/401(k) distributions after age 59½. This makes Pennsylvania competitive for retirees versus Washington State (which also has no state income tax). However, for working-age earners, Washington State's 0% rate on all income beats PA's 3.07% flat rate at every income level.
