Got a commercial building you want to sell but hate the idea of a big tax bill? Follow these steps and keep your capital gains on hold. We’ll walk you through each rule you must obey so the exchange stays valid.
Step 1: Confirm the Property and Transaction Qualify
First, make sure the asset you’re selling qualifies as ” like‑kind” under the tax code. The property has to be held for investment or business use, not for resale. If you own a warehouse, an office tower, or a retail strip, you’re in the clear; a primary residence or a vacant lot meant for flip‑and‑sell doesn’t count.
Next, declare your intent to do a 1031 exchange in the purchase contract. That clause tells the buyer you won’t take cash at closing, which protects the exchange from being busted.
Finally, you need a qualified intermediary (QI) before the sale closes. The QI holds the proceeds in a segregated escrow account and wires the money to the seller of your replacement property. Without a QI, the IRS sees the funds as “constructive receipt” and you lose the deferral.
According to Section 1031 of the Internal Revenue Code, no gain or loss is recognized when you exchange real property held for productive use or investment for another like‑kind property held for the same purpose. That’s the legal backbone of the whole strategy.
Step 2: Build the Exchange Team Before Closing
Now you need a small crew that can keep the clock ticking without a hiccup. Think of it as a project‑management checklist for tax‑deferral.
Our team at 1031 Exchange Timeline: Essential Guide for Investors walks you through each of these roles. We coordinate the QI, run market comps, and keep the paperwork moving.
Pro Tip: Get the QI’s written fee schedule early. Hidden wire fees can bite into your equity if you’re not prepared.
With the crew set, you can focus on pricing and timing instead of scrambling for a missing document.
Step 3: Sell the Relinquished Property Without Taking Receipt of Funds
The sale itself is where many investors stumble. The key is to keep the proceeds out of your hands from day one.
When the buyer wires the money, it goes straight to the QI’s escrow account. You never see a check, never sign a receipt, and never deposit the cash into your own account.
Because the seller never holds the cash, the IRS treats the transaction as a true exchange, not a taxable sale.

Keep the buyer in the dark about the exchange if you can. Some sellers push for a lower price when they know you’re racing against a 45‑day clock. Staying silent protects your negotiating power.
Step 4: Identify Replacement Property Within 45 Days
Day zero is the closing date of your original sale. From that moment you have exactly 45 calendar days to name the new asset.
Write a formal identification notice that includes a full street address or legal description for each property you’re considering. The notice must be signed, dated, and delivered to your QI before midnight on Day 45.
There are three identification rules you can use:
- Three‑Property Rule, up to three properties of any value.
- 200 % Rule, any number of properties, total value ≤ 200 % of the relinquished property.
- 95 % Rule, any number of properties, but you must acquire at least 95 % of the total identified value.
Most investors stick with the three‑property rule because it’s simple and gives flexibility.
Our market analysts at 1031 Exchange for Commercial Real Estate in MA & NH keep a live list of qualified replacement sites in Greater Boston, Essex County, and Rockingham County. We can drop a shortlist into your identification notice so you don’t waste a day.
Step 5: Close the Replacement Property Within 180 Days
After you’ve locked in your list, the next race is to close. You have 180 calendar days from the original sale to take title on one of the identified properties.
The 180‑day clock runs at the same time as the 45‑day clock, so you effectively have 135 days left after you submit your identification notice.
When the closing date arrives, the QI wires the escrowed funds directly to the seller of the replacement property. You never touch the cash.
Any cash or debt reduction that isn’t reinvested, called “boot”, triggers a taxable gain. Make sure the replacement’s purchase price and mortgage are equal to or greater than the relinquished property’s equity and debt.
Our advisors at MANSARD run a final checklist to confirm that the replacement meets the “equal or greater value” rule and that all paperwork, including Form 8824, is ready for filing.
For a closer look at timing, review the exchange’s identification and closing deadlines. The two clocks overlap, making the 45‑day deadline an early pressure point.
FAQ: Common Questions About 1031 Exchange Rules
What is the 45‑day identification deadline?
The 45‑day deadline is the latest date you can formally name replacement property in writing and deliver that notice to your qualified intermediary. It starts the day your original sale closes and includes weekends and holidays.
Can I identify more than three properties?
Yes. You can use the 200 % rule (total value ≤ 200 % of the relinquished property) or the 95 % rule (acquire at least 95 % of the total identified value). Most owners stick with the three‑property rule for simplicity.
What happens if I receive cash back from the sale?
Receiving any cash directly disqualifies the exchange. The IRS treats that as constructive receipt, and the entire gain becomes taxable immediately.
Do I need a qualified intermediary for every exchange?
Yes. A qualified intermediary must hold the sale proceeds in a segregated escrow account and must be named in the exchange agreement before closing.
Is the 180‑day closing deadline absolute?
The 180‑day deadline runs from the sale closing date and does not extend for weekends, holidays, or lender delays. The only exception is a federally declared disaster, which may grant extra days.
What type of property can I acquire?
Both relinquished and replacement properties must be like‑kind U.S. real property used for business or investment.
