The Process

What happens after you pay

Five steps, fully managed. You provide building specs; we deliver IRS-ready documentation your tax advisor can use directly.

01
Intake & scope
We collect your building specs, energy system details, and construction timeline. Takes 20 minutes on your end.
02
Energy modeling
Our engineers run ASHRAE 90.1 compliant energy models for each qualifying system — HVAC, lighting, envelope.
03
IRS certification
We prepare the qualified professional certification required by IRS Notice 2012-26 and the IRA 2022 expansion rules.
04
Documentation package
You receive a complete filing package: Form 7205, energy study report, certification letter, and prevailing wage documentation.
05
Tax advisor handoff
We prepare a one-page summary for your CPA with all figures and citations. They file; you collect the deduction.
Return on Investment

The math is straightforward

For most buildings, our filing fee is a fraction of the deduction — typically a 10–50× return on the filing cost alone.

Common Questions

Before you file

Under current tax law, the enhanced 179D deduction rates (up to $5.94/sq ft) apply to qualifying energy-efficient improvements placed in service before June 30, 2026. After this date, the deduction is eliminated under current legislative proposals. To qualify, your project must be substantially complete by this date — not merely started. Our team helps you assess whether your timeline qualifies.
Yes, the IRS requires that a qualified professional inspect and certify the building. After payment, we coordinate site inspection scheduling. For most buildings under 100,000 sq ft, inspection is typically completed within 5 business days. We manage all scheduling — you just need to provide access.
If our preliminary assessment determines your building doesn't meet the 25% energy reduction threshold required for any qualifying system, we'll refund your filing fee. We conduct a no-cost eligibility screen before beginning the full study — so we'll flag any concerns early.
We deliver a complete package: (1) IRS Form 7205 ready to attach to your return, (2) the qualified professional certification letter, (3) the energy study report with system-level breakdowns, (4) prevailing wage documentation if applicable, and (5) a one-page summary memo with all dollar figures your CPA can use directly. Everything they need is in one package.
Yes. If qualifying improvements were placed in service in 2023, 2024, or 2025, you may be able to file amended returns to claim the deduction retroactively. Tell us your project placement-in-service dates during intake and we'll assess retroactive eligibility as part of your engagement.
For government-owned and tax-exempt buildings, the 179D deduction is allocated to the designer or engineer who designed the qualifying energy systems — not the building owner. If you're an architect, MEP engineer, or energy consultant who worked on such a project, you may be able to claim the deduction. See our A&E designer allocation guide for details.

The deduction won't be here after June 30

Most qualifying buildings see $50,000–$500,000 in deductions. The filing fee is the smallest number in that math. Start now — we need 10–15 business days to complete the study.
