What Is a 1031 Exchange and Why It Matters
Section 1031 of the Internal Revenue Code allows real estate investors to defer capital gains taxes when they sell one investment property and reinvest the proceeds into another 'like-kind' property. Without a 1031 exchange, selling a rental property triggers capital gains tax — typically 15–20% federal long-term capital gains tax plus state taxes and, for high-income taxpayers, the 3.8% Net Investment Income Tax (NIIT). On a property purchased for $200,000 and sold for $500,000 (with depreciation recapture also taxable at 25%), the tax burden can easily exceed $80,000–$100,000, dramatically reducing the capital available to reinvest. A 1031 exchange defers that entire tax bill by treating the sale and reinvestment as a continuous investment rather than a liquidation event. The investor's cost basis carries forward into the replacement property rather than being reset. Critically: the tax is deferred, not forgiven — it accumulates until the investor eventually sells without exchanging. However, if the investor holds replacement properties until death, heirs receive a stepped-up basis (the property's fair market value at death), potentially eliminating the deferred gain entirely. 'Like-kind' is intentionally broad in real estate: any investment or business-use real property qualifies as like-kind to any other investment or business-use real property. A single-family rental can exchange into a commercial building; raw land can exchange into an apartment complex. Primary residences do not qualify. Personal use property does not qualify. The property being sold is the relinquished property; the property being acquired is the replacement property.
