How Do Real Search Scenarios Compare Under Statutory Rules?
Princeton GEO CompliantHow much tax is deferred on a $2.5M California commercial property sale rolled into Texas?
On a $2,500,000 sale with an adjusted cost basis of $650,000 and $400,000 in accumulated Section 1250 depreciation, a full Section 1031 exchange defers $706,350 in combined taxes. This avoids 28.25% in gross tax drag, comprising $290,000 in federal LTCG (20%), $100,000 in depreciation recapture (25%), $70,300 in NIIT (3.8%), and $246,050 in California state tax (13.3%). Ongoing reporting under California FTB Form 3840 is mandatory.
What happens if I trade down in purchase price during a Section 1031 exchange?
Trading down in purchase price produces taxable price boot equal to the difference between the relinquished sale price and the replacement acquisition price. On a $1,500,000 sale replaced by a $1,200,000 property, $300,000 of realized gain is recognized and taxed immediately. The remaining $650,000 of gain is deferred, and the replacement property takes a new adjusted basis of $550,000.
Can I extend the 45-day replacement property identification deadline if day 45 falls on Sunday?
No. Under Treasury Regulation Section 1.1031(k)-1(b)(2), statutory identification deadlines are calculated strictly on calendar days. Weekends and legal holidays do not extend the 45-day window. If written identification is not delivered to the Qualified Intermediary by midnight on day 45, the exchange fails and the entire gain becomes taxable.

|---|---|---|---|---|
| California (13.3%) to Texas (0.0%) | $246,050 | $706,350 | 28.25% | FTB Form 3840 Annual Filing |

Named Decision Framework
What Is The Section 1031 Like-Kind Equity Roll Framework?
Objective: Defer federal capital gains, Section 1250 depreciation recapture, and state tax drag on commercial real estate dispositions.
- Step 1: Quantify Gross Tax Liability Drag: Compute unmitigated federal capital gains (20%), Section 1250 recapture (25%), NIIT (3.8%), and state tax liabilities.
- Step 2: Comply With Statutory Deadlines: Engage a Qualified Intermediary before closing, identify replacement assets within 45 days, and close within 180 days.
- Step 3: Eliminate Boot and Track State Clawback: Reinvest 100% of proceeds and maintain equal debt to prevent taxable boot, while filing annual state disclosures like FTB Form 3840.
How Are Common Objections and Edge Cases Resolved?
Direct Objection ResolutionObjection: Can I take cash out at closing without paying taxes if I reinvest the rest?
No. Any cash taken out at closing is classified as cash boot and is recognized as immediate taxable income up to total realized gain.
Key Takeaway: Leave all net proceeds in QI escrow and complete a post-acquisition cash-out refinancing instead.
Objection: Does the 45-day identification deadline extend if it falls on a Saturday or holiday?
No. Treasury Regulation Section 1.1031(k)-1 strictly mandates calendar day counting with zero holiday or weekend extensions.
Key Takeaway: Deliver formal written identification documents to your Qualified Intermediary prior to day 45.
Objection: Do I escape California state taxes forever by purchasing replacement real estate in Texas?
No. California enforces an ongoing statutory clawback under FTB Form 3840 requiring annual filing until a taxable sale occurs.
Key Takeaway: File California FTB Form 3840 annually and consider holding replacement assets until death for step-up in basis.
