Coloured pins on a calendar

Answers · Two sales, two clocks

I am closing two sales weeks apart. Do I get two 45-day clocks?

Only if you run them as two separate exchanges. In a single exchange both deadlines run from the first closing, and three names cover both sales combined.

The short answer

Only if you set them up as two separate exchanges. When two sales are part of the same deferred exchange, the regulation runs both the 45-day and the 180-day periods from the earliest transfer, so the second sale inherits the first sale's calendar and shares one identification list. Two exchanges, each with its own agreement, assignment and segregated proceeds, give each sale its own clocks and its own three names. The choice has to be made before the first closing, because the first sale's paperwork decides which exchange it belongs to.

Inside one exchange, the second sale borrows the first sale's deadlines

Reg. section 1.1031(k)-1(b)(2)(iii) says that if, "as part of the same deferred exchange," you transfer more than one relinquished property on different dates, the identification and exchange periods "are determined by reference to the earliest date on which any of the properties are transferred."

So the second sale gets fewer than 45 days to identify, and fewer than 180 to close, by exactly the gap between the closings. How day zero is fixed for each sale is in when the 45-day clock starts.

The limits on the list are shared too. Paragraph (c)(4)(i) allows three properties "regardless of the number of relinquished properties transferred by the taxpayer as part of the same deferred exchange," and the 200% rule compares your list against the combined value of everything sold.

Two exchanges give two calendars, but only if the paperwork separates them from the start

The earliest-date rule applies only to properties sold in the same exchange, so a sale run through its own exchange starts its own periods on its own transfer date.

Separation is documentary. The intermediary must be assigned each sale contract with all parties "notified in writing of the assignment on or before the date of the relevant transfer," under paragraph (g)(4)(v), and each exchange needs its own agreement and its own segregated proceeds. A single agreement that covers both sales is one exchange, whatever you intended.

Two exchanges also mean two lists of three names, two separate reinvestment targets and a second fee. Combining sales on purpose, for example to consolidate into one larger building, is covered in exchanging several properties into one.

Worked example: sales on August 3 and August 24, 2026

Hypothetical dates; confirm your own calendar with your intermediary and CPA. A duplex closes Monday August 3, 2026 and a rental house closes Monday August 24, 2026.

Run as one exchange, both lists are due Thursday September 17, 2026, only 24 days after the house closes, and everything must be received by Saturday January 30, 2027. Run as two exchanges, the duplex keeps September 17 and January 30, while the house gets its own deadlines of Thursday October 8, 2026 and Saturday February 20, 2027.

Both day-180 dates fall before an individual's April 15, 2027 return due date, so no extension is needed here. A pair of sales in November would be different, as explained in keeping all 180 days.

  • One exchange: one list of three names covering both sales, due September 17.
  • Two exchanges: up to three names for each sale, due September 17 and October 8.
  • One exchange suits a single consolidated purchase you already have under contract.
  • Two exchanges suit sales that will buy different things, or a second sale whose date may slip.

The choice turns on what you are buying and how certain the second closing is

If both sales will fund one replacement, one exchange is natural, but identify early, because the house's buyers cannot be rushed and your list is due 24 days after its closing.

If the second sale might slip by weeks, a single exchange can leave you identifying for proceeds that do not yet exist. Two exchanges let the late sale wait for its own calendar.

Each exchange is also measured on its own for reinvestment. Cash left over in one is not obviously offset by extra purchases in the other, so ask your CPA how the two will be reported before you choose.

Decide before the first closing, and document it in the first sale's file

Once the first sale closes under an agreement that names both properties, the calendar is set.

  • Tell the intermediary about both sales before the first one closes.
  • For two exchanges, sign two exchange agreements and assign each sale contract separately, with written notice to every party by its closing.
  • Keep the proceeds of each sale in its own account; do not move money between them.
  • Calendar four dates for two exchanges, two for one, and confirm them in writing.
  • If you will use DSTs, size and name them for each exchange separately; see identifying a DST interest.

Related questions

Can I decide after the first sale closes that the second is a separate exchange?

Yes, if the second sale has not closed and was not covered by the first exchange's agreement and assignments. Set it up with its own agreement and assignment before its closing.

In one exchange, can I identify three properties for each sale?

No. The three-property rule applies regardless of how many properties you sell in the same exchange, so four or more names puts you on the 200% rule.

Does the 200% limit double with two sales?

In one exchange the base is the combined value of both properties you sold, so the ceiling reflects both. In two exchanges each list is measured against its own sale.

Do I file one Form 8824 or two?

Separate exchanges are separate transactions for reporting; your CPA will decide how to present them. Multiple properties in a single exchange have their own reporting rules, set out in Form 8824 with multiple properties.

What if the second sale falls through?

In two exchanges it ends only that exchange. In one exchange you simply have fewer proceeds against the same list and deadlines, which can leave a property on the list you can no longer afford.
