Can a life tenant or remainderman do a 1031 exchange?

Each interest is a separate asset with its own owner, basis and exchange

A life estate and a remainder are two interests in the same land. Each holder is the taxpayer for their interest, so each decides whether to exchange, runs their own 45-day and 180-day periods, and must acquire replacement property in the same name, as covered in the same-taxpayer rule.

Both interests can meet the holding test. Reg. section 1.1031(a)-1(b) says real estate held for future use or future realization of the increment in value is held for investment, which describes a remainder well; the life tenant holds for investment or business use if the property is rented or farmed rather than lived in.

The like-kind question is less settled when a life estate alone is exchanged. Reg. section 1.1031(a)-1(c) names a leasehold with 30 years or more to run as like-kind to fee ownership, but it does not mention life estates, and a life estate held by an older person can have a much shorter expected life than that.

Selling together unlocks the basis that a lone life tenant loses

Section 1001(e)(1) disregards the basis of a life interest acquired by gift or inheritance when the life tenant sells it, so the entire amount realized is gain. Publication 544 gives the example of a child who inherits a farm for life and sells the life interest: the whole price is recognized gain.

Section 1001(e)(3) turns that rule off when the entire interest in the property is transferred in one transaction. Under Reg. section 1.1014-5, the uniform basis of the whole property is then divided between the life tenant and the remainderman using the factors in the actuarial tables of Reg. section 20.2031-7 for the life tenant's age on the sale date.

The regulation's own example shows the difference. A life tenant selling alone recognized the full price as gain; when life tenant and remainderman sold the whole property together, the life tenant used their share of basis and recognized a loss.

Worked example: a joint sale splits $1.2 million of proceeds and $500,000 of basis

Hypothetical; the 35% and 65% factors are illustrative, and the real ones come from the IRS tables at the current section 7520 rate; run your own numbers with your CPA. A father's will left a rental farm to his widow for life, remainder to their son, and it was worth $500,000 at his death. Years later both sell the whole farm for $1,200,000.

If the widow's life factor is 35%, her share of proceeds is $420,000 and her share of the $500,000 uniform basis is $175,000, a $245,000 gain. The son receives $780,000 against $325,000 of basis, a $455,000 gain.

Each can defer their own gain by acquiring replacement real estate with at least their share of the proceeds. Had the widow sold only her life estate for $420,000, her entire $420,000 would have been gain.

• Widow, joint sale: $245,000 gain, deferrable on her share.
• Son, joint sale: $455,000 gain, deferrable on his share.
• Widow, selling alone: $420,000 gain, because basis is disregarded.

A life estate the parent kept after deeding the remainder changes the math

When a parent deeds the remainder to children and keeps a life estate, the children's remainder is a gift and takes the parent's carryover basis under section 1015. The payoff usually comes later: section 2036(a) includes in the parent's gross estate property in which they retained possession or income for life, and section 1014(b)(9) then gives that property a basis equal to its value at death.

A joint sale during the parent's life gives that up. The children's share of the proceeds carries the parent's old basis, and if they exchange it the replacement keeps that low basis indefinitely.

So before selling, compare the tax on a sale now with the step-up the family would get by waiting, which is the decision in holding for the step-up and, for older owners, 1031 options for an elderly parent.

What to do, and where trust interests fit

Have the closing documents state the actuarial split, have each holder sign a separate exchange agreement with the intermediary, and have each identify replacement property in their own name. Ask your CPA to compute the factors on the sale date, because the split moves as the life tenant ages and as the section 7520 rate changes.

Shares from an actuarial split rarely match a whole building. Fractional Delaware statutory trust interests, which Rev. Rul. 2004-86 treats as acquirable in a 1031 exchange, let each holder size a replacement to their exact share; see splitting one sale into separate exchanges and traditional DSTs.

If the family wants to keep the life estate and remainder structure in the replacement, that is a title design question for your estate attorney before closing, not after.
