How capital gains tax applies when an Orange County investor sells a rental property, and how a Section 1031 exchange can defer the liability.
Capital gains tax applies when an Orange County investor sells a rental property for more than its adjusted basis. Adjusted basis starts with the original purchase price plus capital improvements, then subtracts depreciation claimed during the ownership period. Because depreciation reduces basis, long held rentals in cities like Anaheim and Santa Ana often carry a much lower basis than their current market value, which produces a larger taxable gain than the simple purchase price to sale price difference would suggest.
The gain on a rental sale is split into two components for tax purposes. The portion attributable to depreciation already claimed is taxed as unrecaptured Section 1250 gain, capped at a 25 percent federal rate, while the remaining appreciation is taxed at long term capital gains rates of up to 20 percent federally, plus the 3.8 percent net investment income tax for higher income investors. California does not recognize a reduced capital gains rate and taxes the entire gain, including the recaptured portion, as ordinary income, with combined state and federal exposure often exceeding 30 percent for Orange County owners in the top brackets.
A Section 1031 exchange defers both the capital gains and the depreciation recapture components as long as the investor reinvests into like-kind replacement real property and follows the 45 day identification and 180 day closing deadlines. Selling a rental outright triggers the full tax bill in the year of sale, while exchanging preserves the equity for continued investment. Orange County owners considering a sale should model both outcomes with a CPA before listing the property, since the deferred tax can represent a significant share of total proceeds.

Frequently Asked Questions
How is capital gains tax calculated on a rental property sale?
Gain equals the sale price minus the adjusted basis, which is the original cost plus improvements minus depreciation claimed. The gain is then split between unrecaptured Section 1250 gain and ordinary long term capital gain.
Why does depreciation increase the taxable gain on a rental sale?
Depreciation deductions reduce the property's basis each year it is held. A lower basis at sale produces a larger taxable gain, even if the sale price only modestly exceeds the original purchase price.
What rate applies to depreciation recapture on rental property?
Unrecaptured Section 1250 gain, which represents the depreciation claimed on real property, is taxed at a federal rate of up to 25 percent, separate from the standard capital gains rate on the remaining appreciation.
Does California tax rental property gains differently than federal law?
Yes, California taxes the entire gain, including depreciation recapture, as ordinary income with no reduced capital gains rate, which can push combined state and federal exposure above 30 percent.
Can a 1031 exchange defer both capital gains and depreciation recapture?
Yes, a properly structured 1031 exchange defers both components as long as the investor reinvests in like-kind real property and meets the identification and closing deadlines.
What happens to a rental owned for decades with significant depreciation?
Long held rentals often carry substantial depreciation, meaning most of the sale proceeds represent taxable gain. A 1031 exchange lets the investor carry that low basis forward without recognizing the gain today.
