Section 179D

Determining whether a project qualifies for Section 179D requires careful evaluation of building systems, timelines and energy performance thresholds. Many owners and design professionals assume eligibility is all‑or‑nothing, when in reality qualification can apply to specific systems or phases of a project.

We begin by evaluating project specifications and construction details with support from specialty professionals. Our team helps clarify whether energy‑efficient improvements meet current standards and identifies where partial or system‑level qualification may apply.

This helps address common challenges such as:

• Uncertainty around eligibility thresholds
• Missed deductions due to partial upgrades
• Confusion between owner‑ and designer‑claimed benefits
• Overlooking eligibility during renovation projects

Energy modeling is essential to substantiate compliance with Section 179D requirements. Accurate modeling demonstrates that energy‑efficient improvements meet or exceed established performance benchmarks.

We coordinate with specialty providers to complete modeling using accepted methodologies and ensure certifications are prepared in accordance with IRS requirements. This approach helps streamline the process and avoid rework late in the project cycle.

This service helps clients:

• Demonstrate compliance with required energy reductions
• Avoid delays caused by incomplete modeling
• Maintain consistency across documentation and filings
• Reduce risk tied to technical substantiation

Section 179D requires certification from an unrelated, licensed professional. Coordinating this step late in a project can create timing challenges or documentation gaps.

We manage coordination with trusted third‑party engineers to ensure certifications are completed efficiently and aligned with project milestones. Our role is to reduce friction between engineering teams, architects and tax advisors.

This helps solve:

• Missed certification windows
• Incomplete or inconsistent certifications
• Delays caused by last‑minute coordination
• Unclear roles between project participants

Claiming the Section 179D deduction requires more than eligibility and certification. Proper documentation must be assembled and retained to support the deduction if reviewed.

We prepare comprehensive documentation packages aligned with IRS expectations and coordinate closely with tax preparers and internal accounting teams to ensure proper reporting.

This support helps clients:

• Reduce audit exposure
• Maintain organized, defensible records
• Apply deductions consistently across projects
• Avoid errors during tax filing
