What it means
Normally, selling an appreciated asset triggers tax on the gain. A like-kind exchange lets an owner swap one qualifying property for another of the same kind and delay the tax, so that more money stays invested.
Under US rules, like-kind treatment has been limited to real property held for business or investment since the 2017 tax reform, so exchanges of equipment, vehicles and similar assets no longer qualify. Real property is interpreted broadly, so a shop could be swapped for farmland or an apartment block.
Strict timing and process rules apply. A qualified intermediary usually holds the sale proceeds, the replacement property must be identified within a short window, and the exchange must be completed within a set period.
If the owner receives cash or other non-qualifying value in the deal, known as boot, tax is due on the gain up to the value of that boot. The deferred gain reduces the tax basis (the cost used to calculate future gains) of the new property.
Deferral can last for many years, even through a series of exchanges. Eventually, tax becomes due when the property is sold for cash, although in some jurisdictions the gain may be eliminated on death, so owners should take tax advice.
The detail differs between countries, and rules change, so this entry describes the principle rather than current rates or deadlines. Investors should confirm the current law with a qualified adviser.
In practice
Real-world examples.
Example
A landlord sells a rental house for $600,000 and uses the proceeds to buy a small apartment block of the same value through a qualified intermediary. No tax is due on the gain in that year. The landlord keeps more capital working in property. The landlord's accountant keeps a schedule of the deferred gain so it can be tracked across future exchanges.
Example
A farming family sells a field next to a growing town and exchanges into a larger farm in another region. Because both are real property held for business use, the exchange qualifies. They defer the tax on the gain until a later sale. They also take advice on how the transaction will be reported to the tax authority each year.
Example
A business owner swaps a warehouse for a retail unit worth less and receives $80,000 in cash. She pays tax on the $80,000 of boot, up to her realised gain, but defers the rest. Her accountant records the new, lower basis. She learns that the cash portion is treated differently from the swapped property, even though it comes from the same deal.
Formula
Calculation
Recognised gain = Lesser of (Realised gain, Boot received)
New basis = Fair value of replacement property - Deferred gain
Suppose an investor sells a building for $900,000 with a tax basis of $400,000, so the realised gain is 900,000 - 400,000 = $500,000. She buys a replacement property worth $850,000 and receives $50,000 of cash boot. Recognised gain = the lesser of $500,000 and $50,000 = $50,000, so the deferred gain is 500,000 - 50,000 = $450,000. The basis of the new property is 850,000 - 450,000 = $400,000. The basis rule matters later. If she sells the new property for $850,000 in cash, her gain will again be 850,000 - 400,000 = $450,000, which is exactly the deferred gain, so the tax postponed from the first sale is caught up at the second.Case study
Seen in the real world.
Larkspur Holdings is an illustrative, fictional property company. It sells an office building for $2,000,000 that cost $800,000, giving a gain of $1,200,000. Selling outright at a 20% tax rate would cost $240,000 in tax.
Instead it exchanges into a $2,000,000 warehouse through a qualified intermediary, deferring the tax. The $240,000 stays invested and earns rental income, though the warehouse carries a lower basis and so lower future depreciation. The numbers are invented, and tax rates vary by jurisdiction and time.
Larkspur's accountant also warned the board that the exchange tied up the company's capital in property for years. The board accepted that, because it planned to hold the warehouse long term and could carry the deferred gain forward through a further exchange later if it chose.
Watch out
Common mistakes.
- Believing the gain disappears. The tax is deferred and may fall due on a later sale. A record of the deferred gain should be kept so that it can be tracked for years.
- Missing the deadlines. The identification and completion windows are strict, and missing them can cancel the benefit.
- Taking the sale proceeds directly. Receiving the cash before the exchange is complete can disqualify it. The intermediary must hold the funds until the replacement property is bought.
Questions
People also ask.
What counts as like-kind?
The test is the nature or character of the property, not its quality, so one piece of investment real estate can be exchanged for another.
What is boot?
Boot is cash or other non-qualifying value received in an exchange, and it is taxable up to the amount of the gain.
Do personal homes qualify?
Generally not, because the exchange must involve property held for business or investment. The rules for selling a main home are separate and usually have their own exclusions.
