Cost segregation is a valuable tax strategy that allows property owners to accelerate depreciation deductions and improve cash flow. However, the approach differs slightly when applied to new construction versus existing buildings. Here’s a breakdown of the key differences:

New Construction Cost Segregation

  1. Optimal Timing:
    • Cost segregation is most effective when conducted during the design and construction phase.
    • Allows for better classification of assets from the outset, reducing the need for later reallocation.
  2. Detailed Cost Breakdown:
    • New construction projects have itemized invoices and clear cost allocations, making it easier to identify assets that qualify for accelerated depreciation.
  3. Eligible Costs:
    • Includes direct construction costs (materials, labor, contractor fees).
    • Site improvements (landscaping, parking lots, sidewalks) can be classified as 15-year property.
    • Interior finishes, specialized electrical and plumbing, and HVAC systems often qualify for 5- or 7-year depreciation.
  4. Immediate Tax Benefits:
    • The property owner can claim accelerated depreciation deductions from year one.
    • Qualifies for bonus depreciation, allowing immediate expensing of certain assets (currently 80% in 2024, phasing out in future years).

Existing Building Cost Segregation

  1. Retrospective Study:
    • Conducted after purchase to reclassify portions of the building into shorter depreciation categories.
    • Often used when acquiring a property that hasn’t previously undergone a cost segregation study.
  2. Challenges with Cost Documentation:
    • Lacks detailed breakdowns of original construction costs.
    • Engineering-based studies are used to estimate costs based on IRS-approved methodologies.
  3. Eligible Costs:
    • Focuses on reclassifying existing components rather than identifying new costs.
    • Leasehold improvements and renovations can be analyzed separately for depreciation benefits.
  4. Catch-Up Depreciation:
    • IRS allows taxpayers to claim missed depreciation deductions without amending prior returns using a Section 481(a) adjustment.
    • Can result in a significant tax benefit in the current year.

Key Considerations

  • Best Timing: Cost segregation is ideal at the start of a new construction project but still highly beneficial for existing buildings.
  • Tax Savings: New construction benefits from better documentation, while existing buildings allow for substantial catch-up depreciation.
  • Bonus Depreciation: Both new and existing buildings qualify, but the impact depends on the type and timing of asset classification.
