The 1031 Exchange, Explained
How to defer the tax when you sell an investment property, the two deadlines that cannot be extended, and the mistake that kills the whole thing.
What a 1031 Exchange Actually Does
Defers the tax. Does not erase it.
Section 1031 of the tax code lets you sell an investment or business use property and reinvest the proceeds into another one without recognizing the gain at that moment. The tax is deferred, not forgiven.
That deferral is powerful because it lets you move your full equity into the next property rather than the amount left after taxes. Investors use it to trade up, to consolidate, or to relocate their holdings to a different market.
It applies to investment property only. Your primary residence does not qualify for a 1031, though it may qualify for the Section 121 exclusion instead. Those are two completely different provisions. My Nevada capital gains page covers the primary residence side.
The Two Deadlines
Both run from the day your sale closes, and neither bends.
45 days to identify
You must identify potential replacement properties in writing to your qualified intermediary within 45 days of closing your sale. Weekends and holidays count.
180 days to close
You must complete the purchase within 180 days of the sale, or by your tax return due date including extensions, whichever comes first.
The identification rules
There are specific rules governing how many properties you may identify and their combined value. Your intermediary will walk you through which one you are using.
The clock starts at closing
Not when you list, not when you go under contract. The day your relinquished property records is day zero.
Forty five days is shorter than it sounds. In a tight market, finding a suitable replacement in that window is the hardest part of the whole exercise. Start shopping before your sale closes, not after.
What Kills an Exchange
Six mistakes, and the first one is fatal and common.
Touching the money
If the proceeds hit your account, the exchange is over. A qualified intermediary must hold the funds from the start.
Setting it up too late
The intermediary has to be engaged before your sale closes. There is no retroactive fix once the sale records.
Missing day 45
The identification deadline is absolute. No extensions for a bad market, a failed deal, or a slow week.
Trading down
Buying cheaper or taking on less debt creates boot, which is taxable. Understand that before you choose the replacement.
Wrong property type
It has to be held for investment or productive use in a business. A property you intend to move into immediately is a problem.
Mismatched title
The entity that sold generally has to be the entity that buys. Changing how title is held mid exchange creates issues.
Say this out loud to your escrow officer early: this is a 1031 exchange. Everyone in the transaction needs to know before closing so the paperwork and the funds route correctly the first time.
Exchanging Into Nevada
A very common move, and there is a wrinkle worth knowing.
Investors regularly sell property in higher tax states and exchange into Nevada, where there is no state income tax on the eventual gain. The properties do not have to be in the same state, which makes this straightforward at the federal level.
The wrinkle is on the other end. Some states track deferred gains from property sold within their borders and expect to be paid when you eventually cash out, even if the replacement property sits elsewhere. California in particular has a claw back reporting regime for this.
I am a Realtor, not a CPA or an attorney. A 1031 is a genuinely technical transaction with unforgiving deadlines and real money at stake. Involve a qualified intermediary and a tax professional before you list, not after. What I can do is help you find the replacement property and keep the timeline realistic.
Line up your intermediary before you close the sale. Once the money touches your account, there is no exchange to save.

Common Questions
Tap any one to open it.
What is a 1031 exchange?
A provision that lets you sell investment or business use real property and reinvest the proceeds into like kind replacement property without recognizing the gain at that time. The tax is deferred rather than eliminated, which lets you move your entire equity forward instead of the portion left after taxes.
Can I 1031 my primary residence?
No. Section 1031 applies to property held for investment or business use. Your primary residence is handled under a different provision, Section 121, which excludes up to $250,000 of gain for a single filer or $500,000 married filing jointly if you meet the ownership and use tests. Mixed use situations get complicated and need a CPA.
Can I exchange from California into Nevada?
Yes, the properties do not need to be in the same state at the federal level, and this is a common move. Be aware that California tracks deferred gains from property sold there and has an annual reporting requirement, expecting its share when the gain is eventually recognized. Talk to a CPA who handles multistate exchanges before you start.
What happens if I miss the 45 day deadline?
The exchange fails and the sale becomes a taxable event. The deadlines are set by statute and there is no ordinary process for extending them. This is why experienced investors have replacement candidates lined up before their sale closes rather than starting the search on day one.
Do I need a qualified intermediary?
Yes, and you must engage one before your sale closes. The intermediary holds the proceeds so that you never take receipt of them, which is what preserves the deferral. If the funds pass through your hands at any point, the exchange is disqualified. Choose one with a solid track record and proper security for the funds.
What is boot?
Any value you receive in the exchange that is not like kind property, including cash you take out and a reduction in debt. Boot is taxable to the extent of your gain. Generally, buying replacement property of equal or greater value and carrying equal or greater debt avoids it. Your CPA will model this before you commit to a replacement.
