A 1031 exchange lets a real estate investor defer the entire tax hit on a sale, federal capital gains, depreciation recapture, the net investment income tax, and New Jersey state tax, by rolling the proceeds into a like-kind replacement property. When it works, it is one of the most powerful wealth-building tools in real estate. When it fails, it fails on the calendar, and the failure is total: the whole gain becomes taxable at once. Getting the 1031 exchange timeline right is the difference.
The two headline deadlines are simple to state: 45 days to identify a replacement property, 180 days to close on it, under Treas. Reg. 1.1031(k)-1 (Cornell Legal Information Institute). The trap is that almost everyone misunderstands how those two clocks relate to each other, and New Jersey adds a step that investors in most other states never have to think about. This guide covers both, with a calculator so you can see your actual dates.
- The 45-day and 180-day clocks run concurrently, both starting the day your sale closes. It is 180 days total, not 45 plus 180. Every day you spend identifying is a day off your closing window.
- Both deadlines are calendar days and non-extendable, even if the 45th or 180th day falls on a weekend or holiday. The only exceptions are federally declared disasters.
- You cannot touch the proceeds. A qualified intermediary must hold the funds from sale to purchase, or the IRS deems constructive receipt and the exchange fails.
- New Jersey fully conforms to Section 1031, but a nonresident seller must file GIT/REP-3 checking Box 7a at closing to claim the exemption. Skip it and the settlement agent withholds the NJ exit tax, and no county clerk will record the deed without the form.
- New Jersey taxes all gain, including depreciation recapture, as ordinary income at graduated rates up to 10.75%, with no long-term capital gain preference, which makes deferring through a 1031 more valuable in NJ than the federal math alone suggests.

Illustrative only. Deadlines are calendar days and are not extended for weekends or holidays. If your sale closes late in the year, your 180-day window may be cut short by your tax-return due date unless you file an extension. This tool does not account for that or for disaster-relief postponements. Confirm every date with your qualified intermediary and CPA.
The Mistake: 45 + 180 Is Not How It Works
This is the single most misunderstood part of a 1031 exchange, and it sinks otherwise well-planned deals. The 45-day identification period and the 180-day exchange period begin on the same day, the day your sale closes, and run concurrently, both measured from the transfer of the relinquished property under Treas. Reg. 1.1031(k)-1(b). The 45 days are part of the 180, not added on top of it.
Put concretely: if your relinquished property closes on July 10, both clocks start July 10. If you use all 45 days to finalize your identification, you do not then get a fresh 180 days. You have 135 days left to close, because the identification period is a subset of the exchange period, not an addition to it. The more time you spend identifying, the less you have to handle financing, inspections, title issues, and lender requirements on the replacement. Investors who treat identification as leisurely and closing as a separate, later problem are the ones who run out of runway in month five.
The 45-Day Identification Rules
Within 45 calendar days of your sale closing, you must identify replacement property in writing, signed and delivered to your qualified intermediary by midnight of the 45th day, per Treas. Reg. 1.1031(k)-1(c). A vague description can invalidate the identification, so each property needs a specific address or legal description. You identify under one of three rules:
Three-Property Rule
Identify up to three properties, regardless of their combined value. This is what most investors use, and it is the first of the three identification methods in Treas. Reg. 1.1031(k)-1(c)(4).
200% Rule
Identify more than three properties, as long as their combined fair market value does not exceed 200% of the value of the property you sold.
95% Rule
If you exceed both the three-property and 200% limits, you must actually acquire at least 95% of the total value you identified. This is risky and rarely used.
Identify more than three properties without satisfying the 200% or 95% rule and the entire exchange can be disqualified under the identification regulations. Most investors stay inside the three-property rule and identify one primary target plus one or two backups, which is the disciplined way to protect against a deal falling through in the closing window.
The 180-Day Closing Rule and the Tax-Return Trap
You must acquire at least one identified replacement property within 180 calendar days of the sale, and the replacement must be one you actually named on your written identification, and the exchange is reported on IRS Form 8824. Simple enough, but there is a second deadline hiding inside the 180 that catches late-year sellers.
The replacement must be received by the earlier of 180 days after the sale or the due date of your tax return, including extensions, for the year of the sale, as stated in IRS Publication 544 and the Form 8824 instructions. If you sell in October, November, or December, your 180-day window naturally runs into the next year, but your tax-return due date may arrive first and cut the exchange period short.
The fix is straightforward: file a tax-return extension so the full 180 days is preserved. Investors who sell late in the year and do not file an extension can lose weeks of their closing window without realizing it.
The Qualified Intermediary and Constructive Receipt
The cardinal rule of execution is that you may never take possession of the sale proceeds. If the money touches your hands or your bank account, even for a single day, the IRS deems constructive receipt and the exchange is blown. A qualified intermediary, an independent third party engaged before your sale closes, holds the funds and then uses them to acquire your replacement.
The QI safe harbor only protects you if the exchange agreement is signed up front and expressly limits your right to receive, pledge, borrow, or otherwise benefit from the cash before the exchange period ends. These are the so-called (g)(6) restrictions under the regulations, and if they are missing from your exchange agreement, the safe harbor fails and the IRS can argue constructive receipt from the moment of sale, under the qualified intermediary safe harbor in Treas. Reg. 1.1031(k)-1(g)(6). This is why the QI has to be in place, and the paperwork signed, before the relinquished property closes, not after.
The timeline, the identification rules, the QI paperwork, and the New Jersey exit-tax step all have to line up before you list. We coordinate the exchange with your qualified intermediary and attorney so the deadlines and the NJ filings are handled before the clock ever starts.
Plan your 1031 exchange with a NJ CPA →The New Jersey Layer: GIT/REP and the Exit Tax
Here is what national 1031 guides leave out, and it matters on every New Jersey deal. New Jersey requires nonresident sellers of NJ real property to make an estimated Gross Income Tax payment at closing, commonly called the exit tax, under N.J.S.A. 54A:8-8 through 8-10 (New Jersey Division of Taxation). No county clerk will record the deed unless the transaction is accompanied by the correct GIT/REP form.
The good news for exchangers: New Jersey fully conforms to Section 1031. If you receive only like-kind property, you claim the exemption by filing GIT/REP-3 and checking Box 7a for full nonrecognition, and no withholding is required (New Jersey Division of Taxation, Form GIT/REP-3). The exchange defers the NJ gain exactly as it defers the federal gain.
The trap is procedural. If that form is not filed correctly at closing, the settlement agent must withhold the exit tax, which is the greater of 10.75% of the gain or 2% of the total sale price, and hold it in escrow (New Jersey Division of Taxation, TB-57(R)). On a $600,000 NJ property, the 2% floor alone is $12,000 pulled out of your proceeds, refundable later but gone at closing. For an exchange, that withholding should never happen, but only if the GIT/REP-3 is prepared and filed as part of the closing package.
Boot: The Partial Exchange Trap
To defer 100% of the tax, you generally must reinvest all of your equity and replace your debt, with the replacement costing at least as much as the net sale price. Anything you keep, cash, a reduction in mortgage debt, or non-like-kind items on the closing statement, is called boot, and boot is taxable in the year of the exchange.
Boot has a specific New Jersey consequence. For a partial exchange where a nonresident receives boot, you cannot simply file the GIT/REP-3 exemption for the whole transaction. You must either file GIT/REP-1 and pay the 2% on the non-exempt portion, or make an estimated payment via NJ-1040-ES on the taxable slice, per New Jersey's partial-1031 procedures in TB-57(R). Plan the numbers so you know before closing whether you are receiving boot and what the NJ payment will be, rather than discovering it when the settlement agent will not release your funds.
A 1031 exchange is one branch of a bigger decision. If you are a developer holding appreciated land rather than a rental, the analysis shifts to preserving investor status, which we cover in investor vs. dealer status for real estate developers. For the broader choice of whether to exchange at all, versus selling outright, doing an installment sale, or holding to step-up, see our guide to selling a rental property, and for the depreciation recapture a 1031 defers, our depreciation recapture guide.
Frequently Asked Questions
Do the 45-day and 180-day 1031 deadlines run one after the other?
No. This is the most common 1031 misunderstanding. The 45-day identification period and the 180-day exchange period both begin on the day your relinquished property sale closes, and they run concurrently. It is 180 days total, not 45 plus 180. If you use all 45 days to identify your replacement, you have 135 days remaining to close, not a fresh 180. Because financing, inspections, and title work all happen in the closing window, spending too long on identification directly shortens the time you have to complete the purchase. Both deadlines are calendar days and cannot be extended for weekends or holidays.
Does New Jersey recognize a 1031 exchange, or do I still owe NJ tax?
New Jersey fully conforms to Section 1031, so a valid like-kind exchange defers the New Jersey gain just as it defers the federal gain. However, a nonresident seller must claim the exemption at closing by filing Form GIT/REP-3 and checking Box 7a for full nonrecognition. If that form is not filed correctly, the settlement agent must withhold the New Jersey exit tax, the greater of 10.75% of the gain or 2% of the sale price, and no county clerk will record the deed without the GIT/REP paperwork. The deferral is real, but the procedural step is mandatory, so it must be handled as part of the closing.
What is the NJ exit tax and how does it interact with a 1031 exchange?
The New Jersey exit tax is an estimated Gross Income Tax prepayment required from nonresident sellers under N.J.S.A. 54A:8-8, equal to the greater of 10.75% of the gain or 2% of the total sale price, collected at closing. In a full 1031 exchange you avoid it by filing GIT/REP-3 Box 7a, since no gain is recognized. If you receive boot in a partial exchange, you cannot claim full exemption: you must file GIT/REP-1 and pay 2% on the non-exempt portion, or make an estimated payment via NJ-1040-ES. Because New Jersey taxes all gain as ordinary income up to 10.75%, the deferral a 1031 provides is proportionally more valuable in New Jersey.
How many replacement properties can I identify in a 1031 exchange?
Under the three-property rule, you can identify up to three replacement properties regardless of their combined value, and this is what most investors use. Under the 200% rule, you can identify more than three as long as their combined fair market value does not exceed 200% of the property you sold. If you exceed both limits, the 95% rule requires you to actually acquire at least 95% of the total value you identified, which is risky and rarely used. Identifying more than three properties without satisfying the 200% or 95% rule can disqualify the entire exchange, so most investors name one target and one or two backups.
What happens if I sell my property late in the year?
The replacement property must be received by the earlier of 180 days after your sale or the due date of your tax return, including extensions, for the year of the sale. If you close in October, November, or December, the natural 180-day window runs into the next year, but your tax-return due date may arrive first and cut the exchange period short. The fix is to file a tax-return extension, which preserves the full 180 days. Investors who sell late in the year and fail to file an extension can lose weeks of their closing window, so this should be planned with your CPA before the sale closes.
Can I hold the sale proceeds myself between the sale and purchase?
No. You may never take actual or constructive receipt of the proceeds. If the funds reach your hands or bank account at any point, even briefly, the IRS treats the sale as taxable and the exchange fails. A qualified intermediary must hold the funds from the sale through the purchase, and the exchange agreement must be signed before the relinquished property closes. The agreement must also include the (g)(6) restrictions that limit your access to the cash during the exchange period; without them, the safe harbor fails. This is why the qualified intermediary is engaged and the paperwork signed before closing, never after.
