The Internal Revenue Service (IRS) has released its annual inflation adjustments for the tax year 2025, bringing significant updates to the Energy-Efficient Commercial Buildings Deduction under Section 179D of the Internal Revenue Code. These changes, detailed in Revenue Procedure 2024-40, are poised to impact building owners, architects, and designers aiming to capitalize on tax incentives for implementing energy-efficient designs and technologies.
Understanding §179D
Section 179D provides a valuable tax deduction for owners and designers of energy-efficient commercial buildings. The deduction is calculated based on the square footage of the building and the extent of energy efficiency improvements achieved, specifically in lighting, HVAC, and building envelope systems. By reducing the building’s total annual energy and power costs compared to a reference building meeting minimum requirements set by ASHRAE standards, taxpayers can claim significant deductions.
Key Adjustments for Tax Year 2025
The IRS has adjusted the applicable dollar values used to calculate the maximum deduction allowances, reflecting inflation and encouraging further investment in energy efficiency. Here are the critical updates:
- Base Deduction Increase:
- Under § 179D(b)(2): The base deduction amount is now $0.58 per square foot, increased (but not exceeding $1.16 per square foot) by $0.02 for each percentage point of energy cost reduction above 25%.
- Implications: This means that for every percentage point your building’s energy efficiency exceeds the 25% threshold, the deduction increases incrementally, maximizing at 50% energy savings.
- Enhanced Deduction for Certain Properties:
- Under § 179D(b)(3): For properties meeting prevailing wage and apprenticeship requirements, the deduction starts at $2.90 per square foot, increasing (but not above $5.81 per square foot) by $0.12 for each percentage point of energy cost reduction above 25%.
- Implications: This enhanced deduction significantly benefits projects that meet specific labor standards, offering a substantial incentive to adopt energy-efficient designs while supporting workforce development.
Practical Impact on Your Projects
The increased deduction limits mean that investing in energy-efficient designs and technologies is more financially rewarding than ever. Here’s how you can benefit:
- Maximize Tax Savings: By achieving higher energy savings, you can qualify for deductions up to $1.16 or $5.81 per square foot, depending on the applicable section.
- Competitive Advantage: Buildings with superior energy performance not only reduce operating costs but also attract environmentally conscious tenants and investors.
- Support Sustainable Practices: These incentives align financial benefits with environmental responsibility, promoting a greener built environment.
Calculating Your Potential Deduction
To determine your eligible deduction:
- Assess Energy Savings: Calculate the percentage by which your building reduces energy costs compared to the baseline.
- Apply the Incremental Increase: For each percentage point above 25%, increase your deduction by the specified amount ($0.02 or $0.12).
- Ensure Compliance: Verify that your project meets all the requirements, including certification by a qualified individual and, if applicable, prevailing wage and apprenticeship standards.
Next Steps for Building Owners and Designers
To take full advantage of these updated deductions:
- Plan Early: Incorporate energy-efficient features into your design from the outset.
- Engage Experts: Work with professionals experienced in energy modeling and certification to ensure compliance.
- Stay Informed: Keep abreast of legislative changes and consult with tax professionals to optimize your benefits.
