What Is 1031 Exchange?

Under Section 1031 of the Internal Revenue Code, a taxpayer can sell an investment or business property and defer the recognition of capital gains taxes by reinvesting the sale proceeds into another qualifying property. The rules are strict: the replacement property must be identified within 45 days of the sale closing, and the acquisition must close within 180 days. The exchange must involve 'like-kind' properties — which in real estate is interpreted broadly, allowing, for example, an apartment building to be exchanged for commercial real estate or land. A qualified intermediary (QI) must hold the proceeds during the exchange — the seller cannot touch the funds. Boot (cash or dissimilar property received in the exchange) is taxable to the extent received. A 1031 exchange only defers taxes, not eliminates them — though if held until death, the heir receives a stepped-up basis that effectively eliminates the gain.

A 1031 exchange can preserve significant capital that would otherwise be lost to taxes — allowing more money to compound in real estate over time. However, the rules are strict and mistakes can trigger the full tax bill. A real estate advisor and tax professional should both be involved to ensure compliance, proper intermediary selection, and strategic property identification within the required timelines.
