What Is a 1031 Exchange?
A 1031 exchange is a strategy real estate investors use to defer paying capital gains tax when they sell an investment property, as long as the proceeds go into another qualifying property.
The basic mechanism
Normally, selling an investment property triggers capital gains tax on the profit. A 1031 exchange (named for the relevant tax code section) allows that tax to be deferred, not eliminated, as long as the proceeds are reinvested into a similar type of property within specific time limits.
Why "deferred" and not "eliminated" matters
The tax obligation doesn't disappear — it carries forward to whenever the replacement property is eventually sold without another exchange. Some investors use this strategy repeatedly across multiple properties over years, continuing to defer, sometimes until the property passes to heirs, at which point the tax treatment changes entirely under separate rules.
The strict timing involved
There are two well-known deadlines: identifying a replacement property within 45 days of the sale, and completing the purchase within 180 days. Both are firm, commonly cited limits with real consequences for missing them.
What counts as a qualifying property
The properties involved generally need to be held for investment or business use, not a personal residence. The replacement property doesn't need to be identical in type — the rules are broader than many people expect regarding what qualifies as "like-kind" real estate.
Why this is a specialist-territory strategy
Between the strict deadlines, the specific qualifying criteria, and the requirement to use a qualified intermediary to hold funds during the exchange, this is not a do-it-yourself tax move — real estate investors considering this typically work with a specialist familiar with the specific rules.

Can a 1031 exchange be used on a primary residence?
Generally no — the property involved needs to be held for investment or business purposes, not used as a personal home, though there are some nuanced exceptions in specific situations.
What happens if the 45-day identification deadline is missed?
Missing it generally disqualifies the exchange entirely, and the sale is treated as a normal taxable transaction — the deadline is strictly enforced with little flexibility.
