1. What is a 1031 Exchange
Section 1031 of the Internal Revenue Code is one of the best wealth-building tools a real estate investor has. When you sell an investment property at a profit, you typically owe federal capital gains tax (up to 20%), depreciation recapture tax (25%), the Net Investment Income Tax (3.8%), and potentially state and local taxes. On a profitable NYC commercial sale, the combined bill can easily exceed 40% of the gain.
A 1031 exchange lets you defer all of these taxes by reinvesting the proceeds into a qualifying replacement property. Note the word "defer": the tax basis carries forward to the new property, so the gain is postponed. Investors can run successive 1031 exchanges for the rest of their lives, and at death their heirs receive a stepped-up basis that effectively wipes out the deferred gain.
Core Requirements of a 1031 Exchange
- Both properties must be held for investment or productive use in a trade or business
- Properties must be "like-kind" (broadly defined for real estate: any real property for any real property)
- A qualified intermediary (QI) must hold the proceeds during the exchange period
- Strict identification and closing deadlines must be met (45 and 180 days)
- The replacement property value must equal or exceed the relinquished property value
2. Qualifying Properties
The Tax Cuts and Jobs Act of 2017 limited 1031 exchanges exclusively to real property. Previously, personal property such as equipment, vehicles, and artwork could also qualify. Today, only real estate held for investment or business use is eligible. For real estate, though, the "like-kind" definition is extremely broad.
Properties That Qualify
- • Office buildings and commercial properties
- • Retail centers and shopping plazas
- • Multifamily apartment buildings
- • Industrial and warehouse facilities
- • Vacant land held for investment
- • Mixed-use properties
- • Triple net leased (NNN) properties
- • Delaware Statutory Trusts (DSTs)
Properties That Do NOT Qualify
- • Primary residences
- • Second homes used primarily for personal use
- • Property held for resale (fix-and-flip)
- • Stocks, bonds, or partnership interests
- • Foreign real property (cannot exchange for US property)
- • Property converted to personal use before sale
That breadth is what makes the 1031 so useful: any type of real estate can be exchanged for any other type. An investor can sell a Manhattan office building and buy a portfolio of NNN retail properties in the Southeast, or sell a vacant parcel and buy a multifamily building. Owners use it to reshape a portfolio, changing asset class or geography, without paying the tax on the way out.
3. Timeline Requirements
Two deadlines govern every 1031 exchange, and both start the day the relinquished property closes. Miss either one and the whole exchange fails, which means the full tax comes due.
The Two Deadlines
45-Day Identification Period
Within 45 calendar days of closing on the sale of your relinquished property, you must identify potential replacement properties in writing to your qualified intermediary. The identification has to be specific, including the address and legal description. The 45 days include weekends and holidays, and there are no extensions.
180-Day Exchange Period
You must close on the replacement property within 180 calendar days of selling the relinquished property (or by the due date of your tax return, including extensions, whichever comes first). The 180-day period starts on the same day as the 45-day identification period and runs alongside it, so the 45 days count toward the 180.
Identification Rules
The IRS provides three methods for identifying replacement properties during the 45-day window:
- Three-Property Rule: Identify up to three properties of any value
- 200% Rule: Identify any number of properties whose combined value does not exceed 200% of the relinquished property value
- 95% Rule: Identify any number of properties if you acquire at least 95% of the aggregate value identified
4. Rules & Restrictions
Full deferral requires the exchange to meet each of the tests below. Fail any one and some or all of the capital gain may be recognized.
Equal or Greater Value
The replacement property must have a purchase price equal to or greater than the net sale price of the relinquished property. Any difference in value is called "boot" and is taxable. Boot can be cash received, debt reduction, or non-like-kind property received in the exchange.
Qualified Intermediary Requirement
The exchanger cannot touch the sale proceeds at any point. A qualified intermediary (also called an accommodator) must hold the funds from the sale through the acquisition of the replacement property. The QI cannot be your agent, attorney, accountant, or anyone who has acted in those capacities within the prior two years.
Same Taxpayer Requirement
The entity or individual that sells the relinquished property must be the same entity or individual that acquires the replacement property. An LLC selling a property cannot have its individual members purchase the replacement in their personal names without triggering tax consequences.
Held for Investment or Business
Both the relinquished and replacement properties must be held for productive use in a trade or business or for investment. The IRS examines the taxpayer's intent at the time of the exchange. There is no specific minimum holding period in the statute, but most tax advisors recommend holding for at least one to two years to demonstrate investment intent.
5. Reverse Exchanges
In a standard (forward) 1031 exchange, you sell first and then buy. A reverse exchange flips this order: you acquire the replacement property before selling the relinquished property. It earns its cost in a market like NYC, where good buildings go quickly and waiting to sell first can mean losing the deal.
How Reverse Exchanges Work
- Exchange Accommodation Titleholder (EAT): An EAT takes title to either the replacement property or the relinquished property during the exchange period, since the investor cannot own both simultaneously.
- Parking Arrangement: Under Revenue Procedure 2000-37, the EAT "parks" the property for up to 180 days while the investor completes the sale of the relinquished property.
- Higher Costs: Reverse exchanges take more work and cost more than forward exchanges, typically $10,000-$25,000 or more in accommodator fees, plus potential additional financing costs.
- Same Deadlines Apply: The 45-day identification and 180-day exchange periods still apply, measured from the date the EAT acquires the parked property.
A reverse exchange makes the most sense for an NYC investor who has found a building they can't replace but needs time to market and sell the one they own. The extra cost can be real money, and it is still small next to the capital gains tax a successful exchange defers.
6. NYC-Specific Considerations
New York City adds its own issues to a 1031 exchange. High property values, state and city taxes, and a competitive buying market all make early planning more important here than elsewhere.
NY State Tax Benefits
New York conforms to federal 1031 exchange rules, so a qualifying exchange defers both federal and state capital gains taxes. With NY state rates up to 10.9% and NYC rates up to 3.876%, the state and city deferral adds up to real money.
Transfer Tax Considerations
NYC transfer taxes (including the mansion tax for properties over $1M) apply to both the sale of the relinquished property and the purchase of the replacement property. These transfer costs cannot be deferred through a 1031 exchange.
Out-of-State Replacement
Many NYC investors use 1031 exchanges to diversify into lower-cost, higher-cap-rate markets. Exchanging a $10M Manhattan property for multiple properties in growth markets like Texas or Florida can sharply increase cash flow while deferring taxes.
Competitive Timing Pressure
In a market as competitive as NYC, finding and tying up replacement properties within 45 days is hard. Experienced investors line up candidates before they sell, and use a reverse exchange when there is a building they can't afford to lose.
Skyline Properties has worked on hundreds of 1031 exchanges for NYC commercial real estate investors. Robert Khodadadian works directly with the client's tax advisors, attorneys, and qualified intermediary so the deal is structured correctly and replacement properties are identified well inside the deadlines.
7. Frequently Asked Questions
What is a 1031 exchange?
A 1031 exchange, named after Section 1031 of the Internal Revenue Code, allows real estate investors to defer paying capital gains taxes when they sell an investment property and reinvest the proceeds into a like-kind replacement property. The exchange must follow strict IRS timelines and rules to qualify.
What is the timeline for a 1031 exchange?
A 1031 exchange runs on two deadlines. You must identify potential replacement properties within 45 days of selling the relinquished property, and you must close on the replacement property within 180 days of the sale. Neither deadline can be extended.
Can you do a 1031 exchange on a primary residence?
No. Section 1031 applies only to property held for productive use in a trade or business or for investment. Primary residences, vacation homes used personally, and property held primarily for resale (such as fix-and-flips) do not qualify for 1031 exchange treatment.
Can I do a 1031 exchange into a property I already own?
No. The replacement property has to be one the taxpayer does not already own at the time of the exchange, so you cannot exchange into a property you currently hold title to. In certain circumstances you can exchange into a property owned by a related party, but special rules and a two-year holding requirement apply.
What happens if I only reinvest part of the proceeds?
Whatever you don't reinvest of the net sale proceeds is treated as "boot" and taxed. If you sell for $5 million and reinvest only $4 million, the $1 million difference is recognized as a taxable gain. Deferring 100% of the tax means reinvesting all of the proceeds and replacing all of the debt.
How many times can I do a 1031 exchange?
As many as you like; there is no limit. Plenty of experienced investors run serial exchanges over their whole careers, deferring the tax each time and growing the portfolio. At death, heirs receive a stepped-up cost basis that effectively wipes out the deferred gains, which is why families use the 1031 as a generational wealth strategy.
Can I exchange into a Delaware Statutory Trust (DST)?
Yes. DSTs are treated as direct property ownership for 1031 exchange purposes under IRS Revenue Ruling 2004-86. DSTs are popular with investors who want to defer taxes and stop managing property themselves. A DST gives you fractional ownership of institutional-quality real estate with professional management, which suits retiring investors and anyone who wants to diversify without being an active landlord.
