OVERVIEW
Pennsylvania and Arizona both use flat income tax rates, but Arizona's is lower at every income level, with no crossover point in Pennsylvania's favor. At $100,000, Pennsylvania residents pay $2,576 versus Arizona's $2,098, a $478/year edge for Arizona that grows to $2,758/year at $500,000. Property tax tells the same one-sided story: Pennsylvania averages 1.58% versus Arizona's 0.63%, a $3,800/year gap on a $400,000 home. Combined, a $100,000 earner with a $400,000 home saves $4,278/year in Arizona — one of the clearest, least nuanced state-tax comparisons on this site. Pennsylvania does hold one card: it doesn't tax any retirement income at all, while Arizona taxes pensions and 401(k)/IRA withdrawals at its 2.5% flat rate (though it fully exempts Social Security). Philadelphia residents face a steep additional 3.79% local wage tax that has no equivalent anywhere in Arizona.

FAQ

Frequently Asked Questions

Is Pennsylvania or Arizona cheaper for state taxes?

Arizona is cheaper at every income level and on both income and property tax. At $100,000, Arizona's income tax bill is $2,098 versus Pennsylvania's $2,576 — a $478/year edge that grows to $2,758/year at $500,000. Add in Arizona's much lower 0.63% property tax versus Pennsylvania's 1.58%, and a $100,000 earner with a $400,000 home saves $4,278/year total by choosing Arizona.

Why is there no crossover point between Pennsylvania and Arizona?

Both states use a flat tax, but Arizona's 2.5% rate is simply lower than Pennsylvania's 3.07% at every dollar of income — there's no bracket structure or larger deduction on either side to flip the outcome. Unlike comparisons involving progressive tax states, this is a straightforward case where one flat rate beats the other flat rate consistently, with the dollar gap widening as income rises.

How much lower is Arizona's property tax than Pennsylvania's?

Arizona averages 0.63% versus Pennsylvania's 1.58% — Pennsylvania's rate is more than double. On a $400,000 home, that's $2,520/year in Arizona versus $6,320/year in Pennsylvania, a $3,800/year difference. This gap adds substantially to Arizona's overall tax advantage on top of its lower income tax.

Does Pennsylvania or Arizona tax retirement income?

Pennsylvania is the more retirement-friendly state on income tax: it fully exempts Social Security, pensions, and all 401(k)/IRA withdrawals from state tax. Arizona exempts Social Security entirely but taxes pensions and 401(k)/IRA withdrawals at its 2.5% flat rate. For retirees relying heavily on pension or 401(k) income, Pennsylvania's income tax exemption can offset some of Arizona's lower property tax and overall rate advantage.

What is Philadelphia's local wage tax and how does it change the comparison?

Philadelphia residents pay an additional 3.79% local wage tax on top of Pennsylvania's 3.07% state rate, for a combined 6.86% — well above Arizona's 2.5% flat rate with no local income tax anywhere in the state. This applies only to Philadelphia residents and workers; the rest of Pennsylvania has no local wage tax, but Philadelphia specifically faces a meaningfully higher total burden than this comparison's statewide figures suggest.

How much would I save moving from Pennsylvania to Arizona at $100,000 income?

At $100,000 income with a $400,000 home: Arizona's income tax edge is $478/year, and its property tax edge is $3,800/year, for a combined savings of $4,278/year moving from Pennsylvania to Arizona. This makes Arizona one of the more clear-cut tax savings destinations for Pennsylvania residents considering a move, particularly for homeowners.

Is Arizona's 2.5% flat tax rate likely to change?

Arizona moved to its current 2.5% flat rate in 2023 after a multi-year phase-down from a progressive bracket system, and it has remained stable since. As of 2026, there are no active legislative proposals to change the rate, though tax policy can shift with future budget cycles or ballot initiatives, as it has in several other states.
