1031 Exchanges for Philadelphia and New Jersey Investors: The 45 and 180 Day Rules
Back
By Max Karasick, Compass real estate agent licensed in PA and NJ
A 1031 exchange lets you sell a rental or other investment real estate, buy replacement real estate and push the tax on the gain down the road, as long as you play by the federal rules. The catch is the clock. Two of them, actually. Both start the day the old property transfers: 45 days to identify replacement property in writing and 180 days to receive it, or the due date of that year's tax return (including extensions) if that comes first. Pennsylvania has followed the federal treatment for exchanges in tax years beginning after December 31, 2022. Realty transfer tax still applies to every deed, though. No exchange gets around that.
This is general information, not tax or legal advice. Set up any exchange with your CPA and attorney before the sale closes.
What a 1031 Exchange Does
The idea is simple. Under Section 1031, no gain or loss is recognized when real property held for business or investment is swapped for like-kind real property. The IRS Instructions for Form 8824 say that since 2018 the rule covers only real property, and not real property held primarily for sale. Real properties are generally like-kind to each other, improved or not, so a Philadelphia rental can be traded for a New Jersey rental or a parcel of land. Publication 544 adds one exception: U.S. and foreign real estate aren't like-kind. Sorry, no swapping the triplex for a villa abroad.
Keep in mind it's a deferral, not a pardon. The tax waits for a later taxable sale. And if you walk away with cash or other non-like-kind property in the exchange, the instructions say gain is recognized to that extent.
The 45 Day Identification Rule
In a deferred exchange you sell first and buy later, and the shopping window is short. Per the Form 8824 instructions, you have to identify replacement property within 45 days after the property you're giving up transfers. For the identification to count, it has to be:
In writing and signed by you, or in a written agreement signed by all parties.
Clear about the property: a legal description, street address or distinguishable name.
Sent within the 45 days to the person obligated to transfer the replacement property to you or to another person in the exchange who isn't a disqualified person.
There's a cap on how many you can name, too. Treasury Regulation 1.1031(k)-1 allows any three properties regardless of value, or any number as long as their total fair market value doesn't top 200% of the value of the property you sold. And if you actually receive the replacement property within the 45 days, the IRS treats the identification requirement as met.
The 180 Day Exchange Deadline and the Year End Trap
The Form 8824 instructions say you have to receive the replacement property by the earlier of two dates: the 180th day after you transferred the old property, or the due date (including extensions) of your tax return for the year of that transfer. Sell late in the year and the return can sneak up first.
Worked Example: A November 2026 Sale
Say a hypothetical investor closes the sale of a Philadelphia rental on November 16, 2026 and files individually on a calendar year:
Day 45: December 31, 2026. Replacement property has to be identified in writing by then. Happy New Year.
Day 180: May 15, 2027.
The 2026 return: due April 15, 2027 for most individuals, which is day 150.
File the 2026 return on time with no extension and the exchange period ends April 15, 2027, a month early. File an extension and you keep the full 180 days. Bring up the extension with your CPA before year end, not in April.
If the exchange fails, the instructions say the gain may be taxable in the year you transferred the property. A November 2026 sale that never finds a replacement is a 2026 gain. So make sure your CPA knows about every exchange in progress when planning year-end estimates.
What a Qualified Intermediary Does
The money can't touch your hands. In a deferred exchange, you can't receive the sale proceeds, so a qualified intermediary holds them. Publication 544 describes one as a person who isn't a disqualified person and who signs a written exchange agreement with you to acquire and transfer the property you give up and to acquire and transfer the replacement property to you. A disqualified person, per the instructions, is generally your agent at the time of the deal or someone related to you. That rules out your real estate agent and your family.
Since the intermediary has to be part of the sale, the exchange agreement needs to be signed before the old property closes. Not after. And if the intermediary makes you miss a deadline, the Form 8824 instructions say the deal may not qualify as a deferred exchange, with a narrow exception for an intermediary in bankruptcy or receivership.
Pennsylvania and New Jersey Rules
Pennsylvania Personal Income Tax
Pennsylvania used to be the odd one out. Before 2023, it taxed these gains even when the IRS didn't. PA Personal Income Tax Bulletin 2006-07, revised September 27, 2022, says Act 53 of 2022 wrote the Section 1031 requirements into Pennsylvania law for exchanges in tax years beginning after December 31, 2022. Now Pennsylvania gain is deferred when the same exchange is deferred federally, and your Pennsylvania basis carries over to the new property.
Realty Transfer Tax on Each Deed
An exchange doesn't dodge transfer tax. The same bulletin says that when title to Pennsylvania real estate moves in a 1031 exchange, the deed is subject to realty transfer tax. If an intermediary takes title, the same property can get taxed on more than one transfer. In Philadelphia, City and state rates together make that a real line item. See the Philadelphia transfer tax guide for current rates and have the title company price each deed in the exchange.
New Jersey
Selling a shore rental from across the river? A nonresident who sells New Jersey real property normally makes an estimated Gross Income Tax payment at closing. TB-57(R), revised June 15, 2026, sets it at the federal gain times the highest New Jersey rate (10.75% per the Division's GIT/REP FAQ, as of October 2026), but never less than 2% of the consideration. The GIT/REP-3 form lets you claim an exemption when gain isn't recognized under Section 1031. If the exchange later fails or only partly qualifies, you agree to file a New Jersey return and report the gain.
Primary Residences and Depreciation
Your home: the Form 8824 instructions say Section 1031 doesn't apply to property used solely as your personal residence. A property used partly as your main home gets split, and the home portion falls under the home sale exclusion covered in Max's guide to capital gains when you sell a home.
Moving in later: Publication 523 says you can't turn replacement property into your main home right after the exchange, because it has to be held for investment or business use. Patience is part of the deal.
Depreciation: Publication 544 says section 1245 recapture can still apply in an exchange. If a cost segregation study moved part of the old building into personal property, ask your CPA what that does to the exchange.
How Max Uses This With Clients
Max isn't a tax advisor, so whether to exchange is your call with your CPA. His job is making the real estate fit the calendar. Before an investor lists, he asks whether an exchange is on the table, so the intermediary is lined up before closing. He maps the 45th day, the 180th day and the return due date from the planned closing. Then he starts the replacement search early enough that the written identification is a short list, not a guess. On a late-year sale, he flags the extension question for the CPA. For more on how he works with investors, see Max's investment services.

FAQ
What are the 45-day and 180-day rules?
You have 45 days after transferring your old property to identify replacement property in writing. Then you have to receive it by the earlier of the 180th day or your tax return due date, including extensions, for the year of the transfer. Both deadlines come from the IRS Instructions for Form 8824. Calendar both.
Can a primary residence be part of a 1031 exchange?
No, not if it's used solely as your personal residence, per the IRS Instructions for Form 8824. A property that's partly your main home and partly business or investment gets split, and the home portion falls under the Section 121 home sale exclusion. Replacement property can't become your main home right after the exchange either.
Does Pennsylvania follow federal 1031 treatment?
Yes, for exchanges in tax years beginning after December 31, 2022. Under Act 53 of 2022, Pennsylvania personal income tax gain is deferred when the same exchange is deferred federally under Section 1031, and your Pennsylvania basis carries over to the replacement property. Pennsylvania realty transfer tax still applies to each deed, though.
What happens if a 1031 exchange closes near year end?
Your exchange period can get cut short, because the tax return due date can land before the 180th day. Sell on November 16, 2026 and day 180 is May 15, 2027. But a 2026 return due April 15, 2027 ends the period at day 150 unless you file an extension.
Do nonresident sellers owe New Jersey tax at closing in a 1031 exchange?
Usually, yes. A nonresident selling New Jersey real property normally makes an estimated Gross Income Tax payment at closing of at least 2% of the consideration. The GIT/REP-3 form lets you claim an exemption when gain isn't recognized under Section 1031. If the exchange fails or only partly qualifies, you file a New Jersey return and report the gain.
