How does a 1031 exchange work when selling an investment property in California?

A 1031 exchange is one of the most powerful tools in a California investor's kit, because it answers the question every profitable seller dreads: what do I do about the tax? The exchange does not forgive the tax; it postpones it, often for decades, by rolling the gain into the next investment. The power comes with strict rules, and those rules decide everything.

What a 1031 exchange actually defers

When you sell an investment property at a profit, you owe capital gains tax on the gain, and California adds its own state tax. A 1031 exchange lets you defer both by reinvesting the net proceeds into another like-kind property for business or investment use. The gain is not erased; it carries into the new property's basis, so the tax waits until you eventually sell without exchanging. That can be generations away.

The timing rules

Two deadlines govern every exchange: you must identify potential replacement properties in writing within 45 days of the sale closing, and you must close on the replacement within 180 days. These are hard deadlines with no extensions. The identification can name several candidate properties within value limits, which is why most exchangers line up replacements before the sale. Missing either deadline turns the exchange into a taxable sale instantly.

Like-kind and what qualifies

Like-kind in real estate is a broad standard: most real property held for business or investment qualifies, from a single-family rental to raw land to a commercial building. The critical exclusions are a personal residence and property held primarily for resale, such as a flip. The exchange must also be equal or up in value and debt to defer the full gain; cash out or a mortgage reduction can create taxable boot.

The qualified intermediary

The proceeds of the sale cannot touch your bank account; they must be held by a qualified intermediary, or QI, who structures the exchange and completes the replacement purchase. The QI is the backbone of the transaction, and choosing a reputable, experienced one is as important as the properties themselves. The costs are modest relative to the tax deferred.

Plan before you list

The golden rule of 1031 exchanges is that the planning happens before the sale, not after: identify the QI, line up replacement candidates, and confirm eligibility with your tax professional. Once escrow closes, the clock is running. Our 1031 exchange guide walks the sequence, and Mike can coordinate the sale and the replacement purchase so neither deadline is missed.
