Capital Gains Tax on Rental Property Explained

Selling a rental property in San Francisco, CA generally triggers capital gains tax on the difference between the sale price and the property's adjusted basis, which is the original purchase price plus qualifying capital improvements, minus depreciation claimed over the holding period. For a duplex in the Sunset District or a small multi-unit building in the Mission that has been rented for years, the taxable gain is often larger than the cash profit an owner expects, because depreciation deductions reduce the property's basis even though the owner never received that depreciation as cash in hand. Owners are frequently surprised at how quickly a modest rental purchased decades ago can generate a six figure taxable gain once basis, selling costs, and depreciation recapture are calculated together by a tax advisor.

Federal and California Tax Layers

Rental property held longer than one year generally qualifies for federal long term capital gains rates, which top out at twenty percent for higher income owners, plus a three and eight tenths percent net investment income tax that applies above certain income thresholds. California does not recognize a separate, lower rate for capital gains. Instead, the state taxes the gain as ordinary income, layered on top of the owner's other California income, at rates that can reach into double digits for higher earners. A rental sale in San Francisco, CA can therefore push a seller into a materially higher state tax bracket for that year alone, even though the gain is a one time event rather than ongoing income.

Depreciation recapture adds a separate layer on top of the general capital gain. The portion of gain attributable to depreciation claimed on the building is generally taxed federally at a maximum rate of twenty-five percent, distinct from the rate applied to price appreciation. San Francisco, CA rental owners who have held property for many years, or who converted a former residence to rental use, often carry significant recapture exposure that a simple sale price comparison does not reveal until a CPA runs the actual basis calculation using purchase records and prior depreciation schedules.

Deferral Through a Section 1031 Exchange

A properly structured Section 1031 exchange allows an investor to defer both the capital gains tax and the depreciation recapture tax by reinvesting the net proceeds into another like kind investment property, rather than paying tax at the time of sale. Rental property, whether a rent controlled duplex, a triplex, or a larger apartment building, generally qualifies as like kind to other real property held for investment, which gives San Francisco, CA owners flexibility to exchange into different property types or different markets entirely. The exchange must follow the forty-five day identification and one hundred eighty day closing deadlines, and the investor cannot take actual or constructive receipt of sale proceeds at any point in the process.

Owners of tenant occupied San Francisco, CA rental property also need to account for local rules, including rent control status and any tenant relocation considerations, when timing a sale and coordinating a subsequent exchange, since tenancy status can affect both marketability and the closing timeline available within the one hundred eighty day window. We help investors map the interaction between local tenancy issues, the sale timeline, and the exchange deadlines before the relinquished property goes to market, so a rent controlled unit's occupancy status does not become a surprise obstacle inside the exchange window.

Because the capital gains calculation depends on basis records that are often incomplete for property held over a long period, we recommend San Francisco, CA rental owners assemble purchase documents, capital improvement records, and depreciation schedules well before listing the property. This preparation lets the owner's CPA calculate an accurate gain estimate, and it lets us help the investor evaluate whether a full exchange, a partial exchange with some boot, or an outright taxable sale best fits their goals.
