Coordinating Depreciation with 1031 Exchanges

In a 1031 exchange, the replacement property inherits the relinquished property's adjusted basis (not its fair market value). If the relinquished property had an original basis of $500,000 with $200,000 in accumulated depreciation, the adjusted basis is $300,000. If the replacement property is purchased for $700,000, the exchange basis is $300,000 (carryover) plus $200,000 in new money (boot paid). The remaining $200,000 represents the deferred gain and deferred depreciation recapture. The depreciation schedule on the replacement property now has two layers: (1) the exchange basis ($300,000) which continues depreciating over the remaining life of the original property's schedule, and (2) any excess basis ($200,000 of boot paid) which starts a new 27.5/39-year depreciation schedule. This two-layer depreciation creates complexity but also creates an opportunity for a new cost segregation study on the replacement property.

The replacement property's excess basis (the boot paid plus any additional mortgage) qualifies for a new cost segregation study. Using our example, the $200,000 in excess basis can be analyzed by an engineering firm and reclassified into shorter-lived components. The exchange basis ($300,000) continues on the relinquished property's original depreciation schedule and cannot be reclassified in a new study. This means the investor gets a "second bite" at cost segregation on the new money invested in the replacement property. If the replacement property has a higher percentage of short-lived components than the relinquished property, the investor can accelerate depreciation on the excess basis while maintaining the exchange basis depreciation.

Step 1: Before listing the relinquished property, confirm the current depreciation schedule and accumulated depreciation with your CPA. Step 2: During the exchange, have the CPA calculate the exchange basis and excess basis for the replacement property. Step 3: Commission a cost segregation study on the replacement property within 60 days of closing—focusing on the excess basis (the portion eligible for new reclassification). Step 4: The CPA creates a two-layer depreciation schedule for the replacement property: Layer 1 (exchange basis continuing the old schedule) and Layer 2 (excess basis with cost-seg-accelerated depreciation and current-year bonus depreciation). Step 5: File the exchange documentation (Form 8824) with the depreciation schedules showing both layers. This workflow preserves the 1031 tax deferral while maximizing depreciation acceleration on the new investment dollars.
