The Problem

This developer had realized a $780,000 capital gain from the sale of a commercial property and was facing approximately $185,000 in combined federal capital gains tax and NIIT. The developer was also planning a new mixed-use construction project in a designated Qualified Opportunity Zone but had not connected the capital gain to the OZ incentive.

The developer's prior advisor had not explored the QOZ program under IRC §1400Z-2, had not considered cost segregation on new construction, and had not evaluated the Section 179D energy deduction.

AE Tax Strategy

1. Qualified Opportunity Zone Fund Under IRC §1400Z-2

We formed a QOZ Fund LLC and invested the $780,000 capital gain within the 180-day window. This deferred the entire gain. If held 10+ years, any appreciation is permanently excluded under IRC §1400Z-2(c). Immediate deferral saved approximately $185,000.

2. Cost Segregation on New Construction Under IRC §168

The cost segregation study reclassified $1,260,000 of the $4.2 million depreciable basis to accelerated recovery periods. Combined bonus depreciation produced approximately $78,000 in additional tax savings.

3. Section 179D Energy Efficient Commercial Building Deduction

The building's high-efficiency design qualified for the full 179D deduction of $5.65 per square foot on the 8,400-square-foot commercial portion, producing approximately $17,000 in additional tax savings.

Total Tax Savings: $195,000 (plus $185K deferred via QOZ)

Key Takeaways

  • Qualified Opportunity Zone investments allow capital gains deferral and, if held 10+ years, permanent exclusion of appreciation.
  • New construction projects should always be evaluated for cost segregation — accelerated recovery periods apply equally to new buildings.
  • Section 179D provides a meaningful per-square-foot deduction for commercial buildings meeting energy efficiency standards.
  • Layering multiple incentives (QOZ + cost segregation + 179D) on a single project can materially change the after-tax return on investment.
