Should I do a 1031 exchange if I'm selling at a loss?

§1031 refuses the loss in two separate places

The operative words in §1031(a)(1) are "No gain or loss shall be recognized," and the section is not optional for a qualifying exchange. §1031(c) repeats the point for the mixed case: where you also receive money or other property, "no loss from the exchange shall be recognized."

So the deduction is not deferred to the closing table and recovered with the boot; it is simply not there. Taking cash out of a loss exchange produces no taxable gain and no deductible loss, which is a strange and expensive place to end up.

Reg. §1.1031(j)-1 applies the same answer where several properties move at once, and its language is blunt: "Losses realized with respect to an exchange group are not recognized."

Run the adjusted basis before you call it a loss

Most apparent losses on long-held rentals are not losses at all. §1016(a)(2) has been reducing basis every year by the depreciation allowed, and never by less than the allowable amount, so the number you compare the sale price against is far below what you paid.

Hypothetical. You bought at $600,000 in 2014, took $150,000 of depreciation, and are selling for $520,000 with $31,200 of selling costs. Adjusted basis is $450,000 and the amount realized is $488,800, which is a $38,800 gain, all of it in the 25% unrecaptured §1250 layer, not a $80,000 loss.

Working out adjusted basis is the step that settles this, and where depreciation was never claimed the answer is the same, as set out on recapture you never deducted.

• Start from the purchase price, add capitalized improvements, subtract all depreciation allowed or allowable.
• Take selling commissions, transfer taxes and title charges off the price to get the amount realized.
• Compare the two figures, not the sale price against what you paid.
• If depreciation exceeds the paper loss, the transaction is a gain sitting entirely in the 25% layer.

A real §1231 loss is ordinary, which makes it worth more than a deferral

§1231(a)(2) provides that where the year's §1231 gains do not exceed the losses, "such gains and losses shall not be treated as gains and losses from sales or exchanges of capital assets," which is what makes the deduction ordinary rather than capital.

The practical difference is the annual ceiling. A capital loss is metered out at $3,000 a year against other income under §1211(b); an ordinary §1231 loss lands in one year against wages, interest and rental income at your marginal rate.

Against that, a 1031 exchange on a loss property defers nothing, because there is no gain to defer, while still costing intermediary and closing fees; the fee side is on what an exchange costs.

If you exchange anyway, the loss moves into the replacement's basis

The loss is postponed rather than destroyed. §1031(d) sets the replacement's basis at "the same as that of the property exchanged," adjusted for money and recognized gain or loss, and since no loss is recognized the high basis carries straight across.

That means a replacement worth less than its tax basis, depreciating from the higher figure and producing a larger loss whenever it is eventually sold. Some owners accept this deliberately to keep a property they want; almost nobody should do it by accident. How basis works after an exchange has the arithmetic.

The real cost of choosing that path is timing: the deduction moves from this April to some year you cannot name, and the §469 suspended losses stay frozen with it.

• The replacement depreciates from the carried-over basis, not from what you paid for it.
• Any suspended passive losses on the old property ride along rather than being released.
• The deferred loss surfaces only on a fully taxable disposition of the replacement.

One loser inside a portfolio sale: close it separately

When several properties sell together and one is under water, keep it out of the exchange documents and give it its own closing. Inside an exchange group its loss is disallowed; outside one it is a deductible §1231 loss that can offset the §1231 gain from the properties that did well.

Practically, that means telling the intermediary which sales are exchange sales before contracts are assigned, and pricing the replacement target from the exchange proceeds only. Exchanging several properties into one covers the structuring, and when one leg closes and another does not covers what happens if the plan slips.

A fully taxable sale of the loss property also satisfies §469(g)(1)(A), which turns the suspended passive losses attached to that activity into ordinary deductions once every dollar of realized gain or loss is recognized and the buyer is unrelated.

• Separate purchase and sale agreements, separate escrows, separate closing statements.
• No exchange cooperation clause in the loss property's contract; see the cooperation clause.
• Proceeds from the loss sale go to you, not to the intermediary.
• Report the loss sale on its own line of Form 4797 in the same year as the exchange.

Two costs of taking the loss that people forget

The first is the five-year lookback. §1231(c) recharacterizes a later net §1231 gain as ordinary income to the extent of ordinary §1231 losses you claimed in the previous five years, so a big deduction now can convert part of a future building sale into ordinary income.

The second is that a suspended-loss release happens once. Using it on a small property while a much larger gain is still coming can waste the timing, which is the sizing question worked through on using losses instead of an exchange.

Have your CPA or attorney verify the basis figure, the §1231 history and the passive loss balance before either contract is signed. Where one property in a portfolio is sold at a loss and the others exchanged, we can size a replacement for the exchange leg alone.
