NJ exit tax, PA's retirement income exemptions, and the property tax tradeoff — quantified. Who actually saves money making this move, and what you need to do before you list your NJ home.
South Jersey and central NJ send a steady stream of retirees across the Delaware River into Bucks and Chester counties every year. The financial case for making the move is real but more complicated than the simple “PA doesn't tax retirement income” pitch most real estate agents give. The NJ exit tax withheld at your closing, PA's higher property tax rate vs NJ's senior relief programs, and the income composition of your retirement portfolio all affect whether the move saves or costs money in the first 5–10 years. Here's the actual math.
New Jersey requires sellers of NJ real property to pay an estimated tax at closing equal to the greater of 8.97% of the gain or 2% of the gross sale price. This is called the Estimated Income Tax Payment and is commonly (though technically imprecisely) called the “exit tax.”
This is not an additional tax — it's a withholding mechanism. Your NJ gain is taxed at NJ's marginal rate, and the withholding ensures NJ collects before you leave the state. If your actual NJ tax liability on the gain is less than withheld, you get a refund when you file your final NJ return. The practical problem is cash flow: the withholding happens at closing, before your refund arrives, and the NJ Division of Taxation takes 6–8 weeks to process the final return.
Calculate your estimated NJ gain (sale price minus your basis, including capital improvements) and multiply by 8.97%. That's approximately how much will be withheld at your NJ closing before you receive your proceeds. If you need those funds to close on the PA property simultaneously, you have a bridge financing problem. Most buyers solve this with a HELOC, a short-term loan, or a sequential close. Talk to your NJ attorney before listing, not after you're under contract.
Pennsylvania exempts from state income tax: all Social Security benefits, all pension income (public and private sector), all distributions from IRAs, 401(k)s, 403(b)s, and similar retirement accounts. New Jersey taxes some of these above certain income thresholds.
NJ tax: SS exempt below $150K combined income — pension taxable above $100K threshold — in this scenario roughly $0–$500 in NJ income tax depending on exact structure.
PA tax: Both SS and pension fully exempt — $0 PA income tax on this $90K.
Annual savings from move: ~$0–$500. Minimal at this income level.
NJ tax: At $150K combined income, SS is partially taxable in NJ; pension taxable above NJ's threshold; IRA distributions taxable. Estimated NJ tax: ~$2,500–$4,500 depending on filing status and exact income composition.
PA tax: SS, pension, and IRA distributions all fully exempt — $0 PA income tax on these sources.
Annual savings from move: ~$2,500–$4,500/year. Meaningful at this income level.
NJ tax: At $200K, significant NJ income tax exposure on pension and IRA income. Estimated $5,000–$8,000 in NJ income tax annually.
PA tax: All three sources fully exempt — $0 PA income tax.
Annual savings from move: ~$5,000–$8,000/year. Very significant.
The key insight: the PA income tax advantage scales with income. Lower-income retirees may see minimal savings; higher-income retirees can save $5,000–$10,000+ annually.
NJ's property taxes are among the highest in the nation at an average effective rate of ~2.1%, but NJ offers three senior relief programs that stack: ANCHOR (up to $1,750 credit), Senior Freeze (locks your base year tax), and Stay NJ (phasing in 50% relief). PA's rates in the Philadelphia suburbs run 1.7%–2.0% — marginally lower or comparable before NJ relief.
| Scenario | NJ (Burlington Co. ~2.56%) + Relief | PA Bucks Co. (~1.8%) + Act 1 | Annual Difference |
|---|---|---|---|
| $300K home, qualifying senior | ~$7,680 less ~$2,500 relief = ~$5,180 | ~$5,400 less ~$700 Act 1 = ~$4,700 | PA saves ~$480/yr |
| $600K home, qualifying senior | ~$15,360 less ~$2,500 relief = ~$12,860 | ~$10,800 less ~$700 Act 1 = ~$10,100 | PA saves ~$2,760/yr |
| $800K home, qualifying senior | ~$20,480 less ~$2,500 relief = ~$17,980 | ~$14,400 less ~$700 Act 1 = ~$13,700 | PA saves ~$4,280/yr |
Burlington County ~2.56% used for NJ; Bucks County ~1.8% for PA. Relief estimates approximate. Verify with county assessors and NJ Division of Taxation.
For a NJ buyer purchasing a $700,000 home in Bucks County with $150,000+ in retirement income: PA property tax savings ~$3,500/year + PA income tax savings ~$3,000–$5,000/year = combined annual advantage of ~$6,500–$8,500. Over 20 years that's $130,000–$170,000 in cumulative savings vs staying in NJ. That more than offsets the NJ exit tax withheld at closing on a typical NJ home sale. The move makes strong financial sense at this income and price point.
1. Calculate your NJ exit tax withholding. Your NJ attorney does this at closing, but you need the number before you list so you can plan cash flow for the PA purchase. Gain = sale price minus your adjusted basis (purchase price + capital improvements). Multiply by 8.97%. That's the approximate withholding.
2. Establish PA domicile as quickly as possible after closing. To claim PA's income tax exemptions for the full year, you need to be a PA domiciliary by December 31. Get your PA driver's license, register your vehicles in PA, and update your voter registration — all within 60–90 days of closing.
3. File your NJ final-year return carefully. You'll file a part-year NJ return for the year of the move. NJ taxes income earned or received while you were a NJ resident. Your PA return covers the PA-resident portion of the year. A CPA familiar with both states' part-year rules is worth the fee.
4. File PA Act 1 Homestead Exemption by March 1. Your first PA tax bill arrives after your first March 1 — if you don't file the exemption before that deadline, you miss a full year of savings. Your settlement attorney rarely flags this.
