Best Time of Year to Start a 1031 Exchange
Most investors think about their 1031 exchange in terms of the property they are selling and the property they hope to buy. Far fewer think about the calendar. But when to start a 1031 exchange matters just as much as which properties are involved, because the IRS clock that governs your exchange runs in calendar days, not business days, and it does not pause for Thanksgiving, Christmas, or a slow week between holidays. An owner who closes a sale in early November can find themselves trying to identify replacement property during the busiest, least productive weeks of the year.
Talk with our exchange team before your sale closes so your identification and exchange periods land on a calendar that actually works for you. Open an exchange with Aspen Exchange and get a clear picture of your deadlines before you sign a purchase agreement.
Why the Calendar Matters More Than Investors Expect
Every 1031 exchange runs on two overlapping deadlines that begin the day your relinquished property closes escrow. You generally have 45 calendar days to formally identify potential replacement properties, and up to 180 calendar days total to close on one or more of them. Both periods are described in detail in our guide to the 3-property, 200%, and 95% identification rules, but the point worth repeating here is simple: these are calendar days. Weekends count. Federal holidays count. If your 45th day lands on Thanksgiving or New Year’s Day, the deadline generally does not move to the next business day the way many contract deadlines do.
That single fact changes how you should think about timing a sale. A closing in early-to-mid October gives you a 45-day identification window that runs straight through Thanksgiving and often into early December, a stretch when sellers, brokers, lenders, and title companies are harder to reach, offices close for extended breaks, and property tours get pushed to “after the holidays.” An investor who closes in late November or December compresses that same 45-day window almost entirely into the holiday season, when inventory can be thinner and decision-makers on the other side of a deal are slower to respond.
The Year-End Closing Squeeze
Year-end closings deserve special attention for a second reason beyond the holidays themselves: the 180-day exchange period can be shortened by your tax filing deadline. If your relinquished property closes late in the calendar year, the standard 180-day window may extend past the due date of your federal income tax return for that year (including extensions). In that situation, the exchange period generally ends on the earlier of the full 180 days or your tax filing deadline, unless you file for an extension of that return to preserve the full window.
This is often called the year-end rule, and it catches investors off guard because they assume they automatically get the full 180 days no matter when they sell. An investor who closes on December 1 and does not file an extension may find their effective exchange period is closer to 105 to 110 days rather than 180, simply because their tax return would otherwise be due before day 180 arrives. Filing an extension for the relevant tax year is a common and straightforward way to preserve the full 180-day window, but it needs to happen deliberately, not as an afterthought discovered in April.
- Closings from roughly October through December deserve extra lead time in planning conversations with your CPA and qualified intermediary.
- Confirm early whether your tax return will need to be extended to preserve the full 180-day exchange period.
- Build in buffer days around bank holidays, since wire transfers and funding for your replacement property purchase can be delayed by closed banks.
- Line up your qualified intermediary before the sale closes, not after, so exchange documents are ready the moment escrow closes.
Planning Ahead If You Know You’ll Sell Within 6 to 12 Months
The investors who navigate timing the best are rarely the ones scrambling after a surprise offer. They are the ones who know, months in advance, that a sale is likely and have already thought through what a replacement property search would look like. If you expect to sell within the next six to twelve months, a few habits make a meaningful difference:
- Start scouting markets and property types early. You do not need to have replacement property under contract before you sell, but having a shortlist of markets, property types, or even specific listings you are watching means your 45-day window is spent narrowing choices rather than starting a search from zero.
- Talk to your lender before you need financing. If your replacement property will involve a new loan, a pre-sale conversation about likely loan terms and underwriting timelines helps you avoid a financing delay eating into your 180 days.
- Ask your CPA about the tax-filing interaction. If a sale might close in the fourth quarter, ask now whether an extension will be needed to protect your full exchange period, and how that interacts with any estimated tax payments due.
- Choose your qualified intermediary before you’re under contract. The relinquished property’s closing documents and exchange agreement need to be structured correctly before funds move, which is difficult to fix after the fact. See our overview of exchange requirements by property type if you’re weighing different asset classes for your next purchase.
- Consider a mid-year closing when you have flexibility. If your sale timing is genuinely negotiable, closing between February and September generally gives your 45 and 180-day windows the most breathing room, away from both summer vacation slowdowns and the holiday compression at year-end.
None of this means a fourth-quarter or holiday-season exchange cannot succeed. Many do, every year. It simply means the margin for error shrinks, and the value of advance planning goes up. An investor who lines up a qualified intermediary, a lender, and a shortlist of replacement properties in September is in a far stronger position for a November closing than one who starts thinking about any of it the week escrow closes.
How Market Timing Interacts With Calendar Timing
Calendar timing is not the only timing question worth asking. Broader market conditions, interest rates, and pricing cycles also shape when an exchange makes sense, and those questions deserve their own analysis. Our article on exchanging in a down market covers that side of the decision in more depth. The calendar-days issue covered here is narrower and more mechanical: regardless of what the market is doing, the IRS clock runs the same way every time, and the time of year you close still determines how much real, usable time you have to execute your identification and closing.
Frequently Asked Questions
Does the 45-day identification deadline move if it falls on a weekend or holiday?
Generally no. The 45-day and 180-day periods are counted in calendar days from the closing date of your relinquished property, and they typically do not extend automatically because the deadline lands on a weekend or federal holiday. Investors should plan to have identification paperwork ready well before the actual deadline date, not on it.
What is the year-end rule for 1031 exchanges?
If your relinquished property closes late enough in the year that the full 180-day exchange period would extend past your federal tax return due date for that year, your exchange period generally ends on the earlier of those two dates unless you file an extension for that tax return. This effectively shortens the 180-day window for many late-year closings if no extension is filed.
Is there a best month to close a 1031 exchange?
There is no single best month for every investor, but closings in the first three quarters of the year generally give the full 45 and 180-day windows more room to run without hitting major holiday slowdowns or the year-end tax-filing interaction. Investors with flexible timing often prefer to avoid closings in November and December when possible.
Can I start looking for replacement property before I sell?
Yes. Nothing in the exchange rules prevents you from researching markets, touring properties, or even negotiating terms before your relinquished property closes. Formal identification for exchange purposes only happens after closing, but doing your homework in advance is one of the most effective ways to make a compressed holiday-season timeline manageable.
Does a federally declared disaster ever extend these deadlines?
In some circumstances, the IRS grants relief that extends 1031 exchange deadlines for taxpayers affected by a federally declared disaster. This is a separate and distinct relief mechanism from ordinary calendar-day planning. See our dedicated article on 1031 exchange disaster extensions for details on how that relief works and who qualifies.
How far in advance should I contact a qualified intermediary?
Ideally before you sign a listing agreement or accept an offer on your relinquished property. The exchange agreement and assignment documents need to be in place before your sale closes, and a QI who understands your timeline can flag calendar risks, like a year-end closing, while you still have time to plan around them.
Plan Your Exchange Before You Sell
The single best way to protect your exchange from a holiday-season time crunch is to start the conversation early. Open an exchange with Aspen Exchange before your sale closes, or contact our exchange team to walk through your specific timeline, including whether a year-end closing might require a tax return extension to preserve your full 180 days.
