INVESTOR RESOURCE
1031 exchange in New Jersey, without the jargon.
Sell an investment property, reinvest the proceeds in like-kind property, and defer the capital gains tax rather than paying it this year. Straightforward in concept, unforgiving on timing.
What qualifies for a 1031 exchange in New Jersey
The test is how you hold the property, not what kind of building it is. Real estate held for investment or used in a business can be exchanged for other U.S. real estate held the same way. A two-unit rental in Middlesex County can become a mixed-use building in Somerset County, or a rental in another state.
| Property | Qualifies? | Why |
|---|---|---|
| Rental house, two-unit or multi-unit | Yes | Held for investment |
| Mixed-use, retail, office or warehouse | Yes | Held for investment or business use |
| Vacant land held for investment | Yes | Improved and unimproved real estate are like-kind |
| Your primary residence | No | Personal use. The Section 121 home sale exclusion applies instead |
| Fix-and-flip property | No | Held for resale, not for investment |
| Vacation home you use yourself | Generally no | Personal use. A narrow IRS safe harbor exists for homes that are mostly rented, so ask your CPA |
| Property outside the United States | No | Not like-kind to U.S. real estate |
| Stocks, REIT shares, partnership interests | No | Not real property |
How boot works in a 1031 exchange
Boot is anything you take out of the exchange that is not like-kind real estate. It usually shows up in two ways: cash you keep, or a mortgage you pay off and do not replace. You pay tax on the boot, up to the amount of your gain, and the rest of the gain stays deferred.
Here is the same sale handled three ways. In each case the investor sells a rental for $900,000 and pays off a $400,000 loan, leaving $500,000 with the Qualified Intermediary.
| What the investor does | Replacement price | New loan | Boot | Result |
|---|---|---|---|---|
| Trades up and reinvests all $500,000 | $950,000 | $450,000 | $0 | Full deferral |
| Buys cheaper and keeps $100,000 in cash | $800,000 | $400,000 | $100,000 cash boot | Tax due on $100,000 |
| Buys cheaper, reinvests all $500,000, borrows less | $800,000 | $300,000 | $100,000 mortgage boot | Tax due on $100,000 |
The third row surprises people. No cash came out, but the debt dropped by $100,000 and nothing replaced it, so the IRS treats that amount as boot. These figures are simplified and leave out closing costs. Your CPA runs the real numbers.
New Jersey rules that affect a 1031 exchange
Section 1031 is federal law, so the 45-day and 180-day deadlines are the same in every state. Three New Jersey points still come up at the closing table.
- State income tax. New Jersey generally follows the federal result, so gain that is deferred under Section 1031 is generally not taxed by the state that year. Boot is taxable for both.
- Out-of-state owners. A nonresident who sells New Jersey real estate normally has to make an estimated Gross Income Tax payment at closing. In a 1031 exchange, the seller claims the exemption on Form GIT/REP-3 and reports the value of the like-kind property received. If there is boot, estimated tax is owed on that part, commonly paid as 2% of the boot when the deed is recorded. The New Jersey Division of Taxation form instructions cover this.
- Selling costs. A 1031 exchange defers income tax on the gain. It does not change ordinary selling costs such as the Realty Transfer Fee. My net proceeds calculator shows what those costs look like on your sale.

Sources and a caution: the federal rules on this page come from the IRS guide to like-kind exchanges. The New Jersey points come from the Division of Taxation. Tax forms, rates and rules change, so confirm the current requirements with your CPA or Qualified Intermediary before you list.
1031 exchange FAQ for Central Jersey investors
How long do I have to complete a 1031 exchange?
You have 45 calendar days from the closing of your sale to identify replacement property in writing, and 180 calendar days from that same closing to buy it. The two clocks run at the same time. If your tax return for that year is due before day 180, file an extension, or the earlier date applies.
Can I exchange a New Jersey rental for a property in another state?
Yes. Any U.S. real estate held for investment or business use is like-kind to any other U.S. real estate held the same way, so a Middlesex County rental can be exchanged for property in Florida or Texas. Property outside the United States is not like-kind to U.S. property.
Do I have to reinvest all of the sale proceeds?
No, but only the part you reinvest is deferred. Cash you keep and debt you do not replace are called boot, and boot is taxable up to the amount of your gain. To defer everything, buy at an equal or higher price and replace both the equity and the debt.
Who can act as my Qualified Intermediary?
An independent company that specializes in exchanges. You cannot hold the funds yourself. Someone who has acted as your real estate agent, attorney, accountant or employee within the past two years generally cannot serve either, and neither can a close relative. That is why I handle the replacement search and leave the funds to the Qualified Intermediary.
What happens if I miss the 45-day deadline?
The exchange fails and the sale is taxed as a regular sale for that year. There is no extension for a deal that falls through or a slow lender. The IRS has allowed extra time only in limited cases, such as federally declared disasters. This is why I start the replacement search before your sale closes, including off-market properties.
Does a two-unit home where I live in one unit qualify?
Partly, in most cases. The rented unit is investment property and can generally go into a 1031 exchange. The unit you live in is treated as your residence and falls under the Section 121 home sale exclusion instead. Your CPA divides the sale price between the two.
WHERE I FIT
The 45-day window is a sourcing problem, and that is my job.
Structuring the exchange belongs to your Qualified Intermediary and your CPA. Finding three viable replacement properties inside 45 days, in a market with thin inventory, is a real estate problem — and it is why investors line up the replacement search before the sale closes rather than after. I keep an eye on Middlesex, Union and Somerset multi-unit and mixed-use inventory, including owners who would sell quietly to the right buyer.
What does not qualify
- Your primary residence. Section 121 is the relevant relief there, not 1031.
- A property bought to flip and resell — held for resale, not for investment.
- Stocks, partnership interests, and since 2018 personal property. Real property for real property only.
