An owner who has depreciated a California commercial or rental property for years is usually staring at two separate tax bills on sale: capital gain on appreciation, and unrecaptured Section 1250 gain on the depreciation already claimed, which is taxed at its own rate rather than the ordinary long-term capital gains rate. A properly structured 1031 exchange defers both pieces together, provided the exchange qualifies in full, but the recapture does not go away, it moves into the replacement property's basis and travels with the owner until a taxable sale finally triggers it.
The recapture calculation itself does not change because an exchange is involved. IRS Publication 544 and the depreciation recapture rules under Section 1250 still determine how much of the gain is attributable to prior depreciation versus appreciation; the exchange only changes when that gain is recognized, not how it is computed. An owner who receives any cash or non-like-kind property in the exchange, commonly called boot, can trigger recognition of gain up to the amount of that boot, and depreciation recapture is recognized first before any remaining gain is treated as capital gain.
California generally follows the federal deferral mechanics for depreciation recapture inside a 1031 exchange, but if the replacement property is located outside California, the recaptured amount becomes part of the California-source gain tracked on FTB Form 3840 for as long as it remains unrecognized.
Recapture is measured against the depreciation actually claimed on the relinquished property, not against some estimate of the building's decline in value. For most commercial and residential rental real estate placed in service after 1986, depreciation is straight-line, so the unrecaptured Section 1250 gain equals the lesser of the total depreciation claimed or the total gain on sale, taxed at a maximum rate that differs from the ordinary capital gains rate.
An owner should pull the full depreciation schedule from every year of ownership, including any component reclassified through a cost segregation study, before estimating what an outright sale would cost. That number is also the baseline for understanding how much of the eventual tax bill an exchange is actually deferring.
Boot is the most common way recapture gets triggered inside an otherwise valid exchange. If the replacement property has a lower purchase price than the relinquished property's net sale price, or if the owner reduces debt on the replacement property without offsetting it with additional cash into the deal, the difference is treated as boot and recognized as gain, with depreciation recapture recognized ahead of any capital gain component under the ordering rules in the Form 8824 instructions.
A partial exchange, where only part of the proceeds is reinvested, produces the same result on the unreinvested portion. An owner planning a partial cash-out alongside an exchange should calculate the boot exposure before closing, not after, since the qualified intermediary cannot undo a completed transaction to fix an unplanned recapture hit.
Once the exchange closes, the replacement property's basis carries over the deferred gain, including the recapture component, and depreciation on the replacement property generally restarts on the carried-over basis using the applicable recovery period for that property type. This means the deferred recapture liability is still sitting inside the property, waiting for a future taxable event, while new depreciation deductions accrue on top of it.
An owner who exchanges repeatedly over a long holding period can end up with a replacement property whose basis is far below its fair market value, almost entirely because of stacked deferred gain and recapture from prior exchanges. That gap becomes highly relevant to any heir or estate plan involving the property, since it determines how large a taxable event a future sale, rather than another exchange, would be.
Depreciation recapture attributable to a California property does not lose its California-source character just because the deferred gain is later carried into an out-of-state replacement property. FTB Form 3840 requires reporting the deferred gain, recapture included, for every year it remains unrecognized, and California taxes that amount when it is eventually recognized, using its own rates rather than the federal recapture rate. The California FTB's instructions for Form 3840 describe this ongoing obligation in detail.
An owner who exchanges a depreciated California property into replacement real estate in another state should expect a California filing obligation to continue indefinitely until the deferred gain, including the recapture portion, is finally recognized in a taxable event or otherwise resolved.
Before marketing a property with significant accumulated depreciation, an owner should get a current basis and recapture estimate from a CPA, not a rough guess from the closing statement of the original purchase. That number drives the decision of whether an exchange is worth the effort and cost relative to simply selling and paying the combined capital gains and recapture tax.
Owners who want to reduce the burden of directly managing another depreciated property, while still deferring the recapture through a qualifying exchange, sometimes look at a Delaware statutory trust interest as replacement property, since it is professionally managed and can accept a wide range of equity amounts. Any decision to use a DST interest should be made only after reviewing the specific offering's documents with a qualified advisor.
