The short answer
Usually the exchange is no longer needed, because the property was still the decedent's at death. Section 1014(a) gives property acquired from a decedent a basis equal to its fair market value at death, so an estate that closes the pending contract weeks later typically reports little gain and sometimes a small loss. The exception is a sale so far along at death that what passed to the estate was a right to the proceeds rather than the property: those proceeds are income in respect of a decedent, get no step-up, and carry the decedent's full gain. The Eighth Circuit's four-part test in Estate of Peterson decides which side of that line a pending contract falls on.
At a glance
| Property owned at death | Basis becomes fair market value at the date of death under section 1014 |
|---|---|
| Holding period | Inherited property is treated as held more than one year, so any gain is long-term |
| Exception | A right to proceeds of a sale completed in substance before death is income in respect of a decedent and gets no step-up |
| Test for the exception | Estate of Peterson: legally significant arrangement, substantive acts done, no material contingencies, decedent would have been paid |
| The contract | The personal representative may perform, compromise or refuse performance of the decedent's contracts |
| The exchange agreement | No exchange has begun until the relinquished property transfers, so the estate can close for cash |
| Value | The willing-buyer price at the valuation date, considering all relevant facts, including a recent arm's-length contract |
Title still in the decedent at death usually means a new basis and a sale with almost nothing to defer
Section 1014(b)(1) covers property acquired "by the decedent's estate from the decedent", and subsection (a)(1) sets its basis at "the fair market value of the property at the date of the decedent's death". A rental the decedent still owned on that date, even one under contract, is such property, and Publication 559 confirms that gain or loss on it "is considered long term, regardless of how long you held the property".
Fair market value is defined in Reg. section 20.2031-1(b) as the willing-buyer, willing-seller price, and "all relevant facts and elements of value as of the applicable valuation date shall be considered". A signed arm's-length contract weeks before death is strong evidence of value, so the date-of-death basis usually lands near the contract price, leaving commissions and costs as the main tax item, the result in selling inherited property within six months. With gain near zero, an exchange defers nothing.
The exception: a sale so complete at death that the estate inherited the proceeds, not the property
Section 1014(c) withholds the step-up from "a right to receive an item of income in respect of a decedent", and section 691(a)(1) taxes such items to the estate when received, with the character they would have had in the decedent's hands. Publication 559's examples include a tractor sold on February 1 with payment due March 1 by a farmer who died on February 15: the gain is income in respect of a decedent.
For a sale still open at death, the Eighth Circuit in Estate of Peterson v. Commissioner endorsed a four-part test: whether the decedent entered into a legally significant arrangement, whether the decedent "performed the substantive (nonministerial) acts required as preconditions to the sale", whether "any economically material contingencies which might have disrupted the sale" existed at death, and whether the decedent would have received the proceeds had he lived. The focus is "the status of the transaction itself at the time of the decedent's death".
In Peterson the decedent had signed a calf sale contract and received earnest money, yet the proceeds were not income in respect of a decedent because substantive acts remained. For real estate, an open financing, inspection, title or due diligence contingency generally leaves the property on the stepped-up side; a contract with every condition satisfied and only recording left is the risky case.
The estate decides whether to close, and the exchange agreement does not have to be used
The buyer's contract binds the estate. Minnesota's enactment of the Uniform Probate Code, section 524.3-715(3), lets the personal representative "perform, compromise or refuse performance of the decedent's contracts that continue as obligations of the estate", so the representative can close as scheduled, renegotiate, or decline and face the buyer's remedies.
The exchange agreement is different. Under Reg. section 1.1031(k)-1 the identification and exchange periods begin when the relinquished property is transferred, and the restriction on access to funds in paragraph (g)(6) applies to an exchange that has begun. A decedent who signed an intermediary agreement but had not yet closed had not started an exchange, so the estate can close for cash without a failed-exchange problem; cancelling before the relinquished closing covers the fee question.
Whoever signs the deed must have authority. An informally appointed representative in Minnesota cannot sell the decedent's real estate until 30 days after letters issue under section 524.3-711, so a closing inside that window needs a formal appointment or a special administrator; see who signs the exchange documents after the seller dies.
Hypothetical: a $1,000,000 contract, a $300,000 basis and a death three weeks before closing
Hypothetical, round numbers. The owner signed a contract to sell a rental for $1,000,000 with the buyer's financing and inspection contingencies open, set up an exchange agreement, and died three weeks before closing with an adjusted basis of $300,000.
If the step-up applies, the estate's basis becomes about $1,000,000. After $60,000 of commissions and costs the estate reports roughly a $60,000 loss, which stays in the estate until its final year and then passes to the heirs, as explained in taxes when an estate sells a rental before distribution, and the exchange agreement is simply not used. If instead the contract had closed in substance before death, the $700,000 gain would be income in respect of a decedent taxed to the estate at the decedent's character, including the depreciation slice, and completing the exchange through the estate would defer it. Have counsel apply the Peterson factors in writing before choosing, and run the numbers with the estate's CPA.
- Step-up applies: basis about $1,000,000, small loss after costs, no exchange needed.
- Income in respect of a decedent: $700,000 of gain, no step-up, exchange worth completing.
- The deciding facts: which contingencies were still open on the date of death.
When the estate should still run the exchange
Complete the exchange when the Peterson analysis points to income in respect of a decedent, because deferral then has real value, or when the estate will hold the replacement for years and the heirs want a passive asset rather than cash; an estate can exchange in its own right, as the executor's guide explains. A Delaware statutory trust interest on the list closes by subscription if time is short, but it is illiquid until the trust sells and can lose value; the traditional DST describes the structure.
Where there is no income-in-respect-of-a-decedent risk and the heirs want cash, close for cash and let the step-up do its work. Whether an estate's rental should be exchanged at all once the basis has reset is covered in an executor selling an estate's rental, and the mid-exchange case, where the sale had already closed, in what happens if the owner dies during a 1031 exchange.
Related questions
Does the buyer have to wait for the probate court before closing?
Someone with authority has to sign the deed, so yes in practice. A formal appointment, or a special administrator appointed to protect the estate, can usually be obtained within days; an informal appointee in some states cannot sell real estate for 30 days after letters issue.
Is the gain short-term if the estate closes a month after death?
No. Section 1223(9) treats property acquired from a decedent and sold within a year of death as held for more than one year, so any gain over the date-of-death basis is long-term.
The decedent already paid the intermediary. Is the estate locked into the exchange?
No. An exchange begins when the relinquished property transfers, which had not happened. The estate can close for cash; whether any part of the fee is refundable is a term of the intermediary's agreement, not a tax rule.
The buyer paid an earnest money deposit before death. Does that make the proceeds income in respect of a decedent?
Not by itself. In Estate of Peterson the decedent had received earnest money and the proceeds were still not income in respect of a decedent, because substantive acts remained. The deposit is one fact; the open contingencies matter more.
What value does the estate use if no estate tax return is required?
Fair market value at the date of death, supported by an appraisal that can cite the contract price. If a Form 706 is required, section 1014(f) requires the heirs' basis to be consistent with the value finally determined for estate tax.
