Pennsylvania is cheaper to live in and New Jersey pays better, and for most households that trade decides it. Census figures for 2020 to 2024 put New Jersey’s median household income at $103,556 against Pennsylvania’s $77,971, but the median owner occupied home costs $454,400 in New Jersey and $254,500 in Pennsylvania. Add New Jersey’s property tax bills, among the heaviest in the country, and Pennsylvania’s flat 3.07 percent income tax, and the picture gets clear fast.
Both states sit in the same corridor, share a border along the Delaware River, and pull from the same job markets, so this is less a lifestyle contrast than a cost and tax contrast. What follows uses figures published by the Census Bureau, the New Jersey Division of Taxation, and the Pennsylvania Department of Revenue, with the year attached to anything that moves.
The headline numbers side by side
| Measure | New Jersey | Pennsylvania |
|---|---|---|
| Population (July 2025) | 9,548,215 | 13,059,432 |
| Median household income (2020 to 2024) | $103,556 | $77,971 |
| Median home value (2020 to 2024) | $454,400 | $254,500 |
| Median gross rent (2020 to 2024) | $1,720 | $1,209 |
| State income tax | Graduated, 1.4 to 10.75 percent | Flat 3.07 percent |
| State sales tax | 6.625 percent | 6 percent, plus 2 in Philadelphia, 1 in Allegheny County |
| Average residential property tax bill | $9,898 statewide in 2024 | No comparable statewide figure published; generally far lower |
Two things stand out. First, the income gap is real but smaller than the housing gap. New Jersey households earn about 33 percent more, while New Jersey homes cost about 79 percent more. Second, Pennsylvania’s flat tax is genuinely flat: there is no bracket to climb into, and the same 3.07 percent applies to a first job and a senior engineering salary.
Income tax: flat simplicity against a graduated ladder
Pennsylvania levies personal income tax at 3.07 percent on eight classes of income with no standard deduction and no personal exemption. It is one of the simplest state returns in the country, and the rate is published on the Pennsylvania Department of Revenue tax rates page. Retirement income is the quiet advantage: Pennsylvania does not tax Social Security, and it does not tax distributions from qualified retirement plans once you have reached retirement age.
New Jersey runs graduated brackets that begin at 1.4 percent and top out at 10.75 percent, with the highest rate reserved for income above $1 million. For a household earning around the state median, the effective New Jersey rate lands well below Pennsylvania’s flat rate once exemptions and the lower brackets are applied. The crossover happens as income climbs. High earners pay materially more in New Jersey.
So the income tax comparison is not a simple win for either side. A teacher and a nurse in a two income household may pay less state income tax in New Jersey. A pair of software engineers clearing $400,000 will not.
The reciprocity agreement, and what it does not cover
New Jersey and Pennsylvania have a reciprocal personal income tax agreement, and it is currently in effect. Under it, compensation paid to a Pennsylvania resident working in New Jersey is exempt from New Jersey income tax, and the reverse holds for New Jersey residents working in Pennsylvania. You file only in your home state on wages. Employees claim the exemption with NJ-165 going one way and REV-419EX going the other.
There was an attempt in 2016 to end the agreement, which was reversed before it took effect. It has been in continuous operation since, but it is a policy that either governor could revisit, so it is worth checking rather than assuming.
Property taxes and what you actually pay to live somewhere
New Jersey’s statewide average residential property tax bill was $9,898 in 2024 according to the Division of Taxation. That is the number that shapes household budgets across the state, and it is the single biggest reason people leave. It also buys something: New Jersey funds public schools heavily through local property tax, and school quality across much of the state reflects that spending.
Pennsylvania does not publish an equivalent statewide average bill, and rates vary enormously by school district. What is safe to say from the underlying data is that Pennsylvania bills are lower on average, largely because assessed values are lower and county rates are less uniform. A township in Bucks County near the Philadelphia line can approach New Jersey territory. A borough in the western part of the state will not come close.
If you are comparing two specific addresses rather than two states, pull the actual assessment and millage for each. State averages hide swings of several thousand dollars within a single county. The same logic applies when you compare across regions, as our look at New York against Ohio shows.
Commuting, transit, and where the jobs are
New Jersey is built for commuting. NJ Transit rail and bus, PATH into Manhattan, PATCO into Philadelphia, and Amtrak on the Northeast Corridor all move large numbers of workers daily. If you want a job in New York City without living in New York City, northern New Jersey is the default answer, and the wage premium in the state’s income figures reflects that access.
Pennsylvania is more regional. SEPTA serves the Philadelphia area well, Pittsburgh has a functional but smaller system, and everything between is car country. The Lehigh Valley and the counties north of Philadelphia have grown as warehouse, logistics, and healthcare employers expanded, and those jobs pay less than New York finance but come with far cheaper housing.
Schools, healthcare, and daily life
New Jersey’s public schools benefit from high per pupil spending, driven by those property taxes, and the state’s district level results are consistently strong. Pennsylvania’s picture is more uneven: several suburban Philadelphia and Pittsburgh districts perform at a similar level, while funding disparities between wealthy and poor districts are wider than in New Jersey.
Healthcare access is strong in both. The Philadelphia academic medical corridor serves southern New Jersey and eastern Pennsylvania alike, and northern New Jersey draws on the New York City hospital network. Neither state leaves you far from a major medical center unless you choose a genuinely rural area, which Pennsylvania has far more of.
Weather is close to identical. Both get four real seasons, humid summers, and winters that vary more with elevation than with the state line. Pennsylvania’s northern and western counties get meaningfully more snow than the New Jersey shore.
Who should pick which
Pick New Jersey if you want proximity to New York City jobs, you value transit that works without a car, you have school age children and want reliably funded districts, or your income is in a range where the graduated brackets treat you gently.
Pick Pennsylvania if you want to own a home sooner, you earn a high salary and want a flat 3.07 percent instead of a top bracket, you are retiring and want retirement income left alone, or you simply want the same square footage for a lot less money.
The border case deserves its own note. Living in Bucks County and working in New Jersey, or living in Cherry Hill and working in Philadelphia, is a common arrangement that the reciprocity agreement makes workable. Just budget for the Philadelphia wage tax if that is where your office sits.

Residency rules, filing obligations, and how the reciprocity agreement applies to your specific income all depend on facts we cannot see.

Frequently asked questions
Is the New Jersey and Pennsylvania reciprocity agreement still in effect?
Yes. The New Jersey Division of Taxation confirms the agreement is active. Wages earned by a resident of one state working in the other are taxed only by the home state. It does not cover self employment income, business income, or gains from property sales, which still require a nonresident return.
Which state has lower property taxes?
Pennsylvania, on average, by a wide margin. New Jersey’s statewide average residential bill was $9,898 in 2024. Pennsylvania does not publish a directly comparable figure, but its assessed values and effective rates are lower across most of the state, with wide variation between school districts.
Do I pay Philadelphia wage tax if I live in New Jersey?
If you work in Philadelphia, the city wage tax generally applies to nonresidents on income earned within the city. The state reciprocity agreement does not exempt you from local wage taxes. New Jersey typically allows a credit for that local tax, but you should confirm the current treatment with a tax professional.
Is New Jersey better for families than Pennsylvania?
New Jersey has more consistently funded public schools and better transit, which many families weight heavily. Pennsylvania offers more house for the money and lower fixed costs, which frees up income for other things. The right answer depends on whether you value the district or the mortgage payment more.
Which state is better for retirees?
Pennsylvania has the stronger case on tax. It does not tax Social Security and it does not tax qualified retirement plan distributions once you reach retirement age. New Jersey has a pension exclusion but applies it within income limits, and its property taxes remain a major fixed cost in retirement.
The bottom line
Pennsylvania wins on cost. Lower home prices, lower rent, a simple flat income tax, and property tax bills that generally run well below New Jersey’s mean your money stretches further, and the gap is large enough that it shows up in the first mortgage statement rather than in a spreadsheet.
New Jersey wins on access and income. Higher wages, dense transit, and proximity to two major job markets are things Pennsylvania cannot match outside Philadelphia. If the higher salary you can earn in New Jersey exceeds the higher costs you will pay there, stay. If it does not, cross the river.
