How a 1031 Exchange Defers the Tax Bill

A 1031 exchange defers the tax that would normally hit a commercial property sale by moving the sale proceeds into a replacement property rather than back to the seller. The IRS treats the transaction as a continuation of the original investment rather than a taxable event. The gain, and the depreciation the owner has been taking for years, stay embedded in the replacement property basis instead of showing up as a check to the federal and state governments.

For a Macomb County commercial owner who bought an industrial building for $650,000 fifteen years ago and is looking at selling for $1.4 million, the deferred amount is significant. Federal capital gains at 20 percent on the $750,000 appreciation is $150,000. Depreciation recapture at 25 percent on the roughly $250,000 of depreciation taken over fifteen years is another $62,500. Michigan state tax at 4.25 percent on the combined gain adds another $42,500. The combined tax bill approaches $255,000 without a 1031 exchange. That is $255,000 that stays working in the replacement property instead of paying tax.

The mechanism works through a qualified intermediary, or QI. When the relinquished property closes, the sale proceeds go to the QI rather than the seller. The seller cannot touch the funds during the exchange window. The QI holds the money and then wires it directly to the closing agent for the replacement property. Because the seller never had constructive receipt of the cash, the transaction qualifies for tax deferral under Section 1031.

The tax deferred is not tax forgiven. The gain and depreciation recapture carry forward into the replacement property. When the replacement property eventually sells without another exchange, all the deferred tax comes due at that point. Some owners chain exchanges across decades, deferring and compounding, and then pass property to heirs. Under current stepped up basis rules, the heirs receive the property at fair market value at death, and the deferred tax effectively disappears.

What qualifies for deferral matters. Both properties must be held for investment or business use. A vacation home used personally does not qualify. A primary residence does not qualify. Both must be considered like kind, which under current rules means any real property held for investment qualifies as like kind to any other real property held for investment. A Macomb County flex building can exchange into a retail strip, an apartment building, or even an out of state investment property.

The tax deferred stays intact only if the exchange follows the technical rules. The replacement property must be identified within 45 days of the original sale closing. The replacement must be purchased within 180 days. The replacement must be of equal or greater value. Any leftover cash, called boot, gets taxed at full rates. Any debt reduction from the sale to the replacement also counts as boot and gets taxed.

Michigan adds a specific consideration on the replacement side. Michigan uncaps property tax to state equalized value at sale, so the replacement property tax bill will typically exceed what the seller of that property was paying. The 1031 defers federal capital gains, depreciation recapture, and Michigan state income tax on the gain, but it does not affect the property tax uncapping. Buyers should underwrite replacement property NOI using post sale property tax estimates.
