Like-kind exchange

1031 exchange

A 1031 exchange defers capital gains tax and depreciation recapture by rolling the proceeds of an investment-property sale into another investment property. The deadlines are strict and statutory: 45 days from closing to identify replacement property in writing, 180 days to close on it, and the proceeds must never touch your hands — a qualified intermediary holds them.

Deferred tax = (capital gain × capital gains rate) + (depreciation × 25%)

Worked example

Selling with $60,000 of gain and $80,640 of accumulated depreciation defers roughly $29,000 of federal tax into the next property.

Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.

The mistake to avoid

Missing the 45-day identification window. It runs on calendar days including weekends and holidays, there is no extension, and a blown identification collapses the exchange entirely.
