What Is the 1031 Exchange Timeline in Los Angeles?
Justin Borges, DRE #01940318 · 11 min read · Updated July 26, 2026
The 1031 exchange clock starts the day escrow closes on the relinquished property, day 0. Replacement property must be identified in writing by day 45, and the purchase must close by day 180, or by the investor's tax return due date if earlier. Every calendar day counts, including weekends and holidays (IRS, IRC Section 1031(a)(3)).

What Is the Day-by-Day 1031 Exchange Timeline?
The clock starts the day escrow closes on a Los Angeles County relinquished property, counted as day 0. From that date, an investor has exactly 45 calendar days to identify replacement property in writing to the qualified intermediary, and exactly 180 calendar days to close on the replacement purchase, or until the investor's tax return due date for that year, whichever comes first (IRS, IRC Section 1031(a)(3)).
| Milestone | Deadline | What Must Happen |
|---|---|---|
| Relinquished property closes | Day 0 | Sale proceeds transfer to the qualified intermediary |
| Identification deadline | Day 45 | Replacement property identified in writing |
| Completion deadline | Day 180 | Replacement property purchase closes |
| Tax return due date cutoff | Whichever is earlier | Exchange must complete before the return is filed |
Forty-five days sounds like plenty of time until you are also closing the sale that started the clock. Most investors underestimate how fast it actually moves.
Justin Borges, CA DRE #01940318Does a Weekend or Holiday Extend the 45-Day or 180-Day Deadline?
No. Both the 45-day identification deadline and the 180-day completion deadline count every calendar day, including weekends and federal holidays, with no automatic extension if day 45 or day 180 happens to land on one (IRS, IRC Section 1031(a)(3)). This is a meaningful difference from many other tax and legal deadlines that push to the next business day when they fall on a weekend.
An investor exchanging a Los Angeles County property should mark the exact calendar date of both deadlines the moment escrow closes, rather than estimating "45 business days" or assuming a weekend buys extra time. Missing either deadline by even one day disqualifies the exchange entirely.
Can a Federally Declared Disaster Extend a 1031 Exchange Deadline?
Yes, under IRC Section 7508A, the IRS has authority to postpone 1031 exchange deadlines for taxpayers affected by a federally declared disaster. This relief is not automatic; it applies only when the IRS specifically issues a postponement notice tied to a particular disaster declaration and geographic area, and an investor has to confirm their specific transaction and location actually qualify under that notice rather than assuming relief applies broadly.
Los Angeles County investors whose relinquished or replacement property, or whose qualified intermediary, sits within a federally declared disaster area should check IRS disaster relief announcements directly rather than assuming an extension applies. Absent a specific IRS notice, the standard 45-day and 180-day deadlines control with no built-in disaster buffer.
Because this relief depends on an IRS notice tied to a specific disaster declaration and geographic scope, an investor cannot simply assume protection exists just because Los Angeles County has experienced a recent emergency. Confirming with a qualified intermediary or tax professional whether a specific notice actually covers the investor's county, property address, and transaction dates is the only genuinely reliable way to know whether the standard deadlines have actually been postponed for a given Los Angeles County exchange, rather than guessing based on news coverage of the disaster itself.
What Should You Do in the First 45 Days After Closing?
A qualified intermediary needs to be lined up before the relinquished Los Angeles County property even closes, since the exchange structure has to be in place at the time of sale, not arranged afterward. Once escrow closes and the 45-day clock starts, the priority is identifying replacement property in writing under one of the IRS identification rules: the 3-Property Rule, the 200% Rule, or the 95% Rule.
- Days 1 to 15: confirm the qualified intermediary is holding proceeds correctly and begin actively touring replacement candidates.
- Days 15 to 35: narrow to serious candidates and begin due diligence, since a written offer takes time to negotiate before identification is finalized.
- Days 35 to 45: finalize the written identification with the qualified intermediary well before the deadline, not on the final day.
Does Financing the Replacement Property Add Timeline Risk?
An investor financing the Los Angeles County replacement property, rather than paying cash, adds a second clock running in parallel with the 180-day exchange deadline: the lender's own underwriting timeline. Conventional financing underwritten to Freddie Mac and Fannie Mae guidelines typically closes in 30 to 45 days once a purchase contract is signed, which usually leaves comfortable room inside 180 days, but only if the identification and negotiation phase in the first 45 days did not already consume most of the available runway.
An investor who spends the full 45 days identifying a replacement property, and then still needs a 30-to-45-day financed closing, is working with a tighter margin than one who identifies a property in the first two weeks. Getting fully underwritten by a lender before the 45-day identification window even opens, rather than after, is one of the more reliable ways to protect the back half of the 180-day timeline (IRS, IRC Section 1031(a)(3)).
How Does Your Tax Return Due Date Interact With the 180-Day Deadline?
The completion deadline is 180 days from the relinquished property's closing, or the investor's tax return due date for that tax year, including any extension actually filed, whichever comes first. For a Los Angeles County exchange that closes late in the calendar year, this can shorten the effective window well below the full 180 days unless the investor files a tax extension.
An investor whose relinquished property closes in November or December should confirm with a tax professional whether filing an extension is necessary to preserve the full 180-day window, since failing to do so can force the exchange to complete on an accelerated timeline tied to the standard tax filing deadline instead.
Frequently Asked Questions
What is the 1031 exchange timeline for Los Angeles investors?
The clock starts the day escrow closes on the relinquished property (day 0). Replacement property must be identified in writing by day 45, and the purchase must close by day 180, or by the investor's tax return due date if earlier (IRS, IRC Section 1031(a)(3)).
Does a weekend or holiday extend the 45-day or 180-day deadline?
No. Both deadlines count every calendar day, including weekends and federal holidays, with no automatic extension if day 45 or day 180 happens to fall on one.
Can a federally declared disaster extend a 1031 exchange deadline in California?
Yes. Under IRC Section 7508A, the IRS can postpone 1031 exchange deadlines for taxpayers affected by a federally declared disaster, but this relief is only available when the IRS specifically issues it for a given disaster, and it is not automatic.
What should you do in the first 45 days after closing a 1031 exchange?
Line up a qualified intermediary before closing the relinquished property, then use the 45-day window to identify replacement property in writing, following the 3-Property, 200%, or 95% identification rule.
What happens if you miss the 45-day identification deadline?
Missing the 45-day identification deadline disqualifies the entire exchange, and the transaction is treated as a normal taxable sale with no extension available outside a federally declared disaster.
Can the 180-day deadline be shorter than 180 days?
Yes. The completion deadline is 180 days from the relinquished property's closing, or the investor's tax return due date (including extensions), whichever comes first, which can shorten the window for an exchange that closes late in the calendar year.
