Maximizing Green Building Tax Incentives for Multifamily Developers and Homebuilders

Green Building Tax Incentives for Homebuilders Denver, Fort Collins, Santa Fe, Albuquerque

Green building tax incentives: As the world prioritizes sustainability, green building practices have become increasingly important for developers and builders. 

With the environmental benefits, there are also many financial incentives for those who incorporate green building practices into their projects. 

The Inflation Reduction Act (IRA) offers several federal tax incentives for green building, including the 45L Tax Credit, 179D Tax Deduction, and 25C Tax Credit.  

Let’s explore these tax incentives and discuss how multifamily developers and homebuilders can maximize their benefits.

The 45L Tax Credit – Green Building Tax Incentive

The 45L Energy-Efficient Home Tax Credit offers contractors and builders a way to offset the expenses of constructing energy-efficient single-family or multifamily properties. 

45L provides a dollar-for-dollar reduction in their taxes owed or paid during the tax year when the property is sold or leased.

The Internal Revenue Code (IRC) Section 45L offers a credit per dwelling unit for every newly constructed energy-efficient home. 

This credit applies to homes built by eligible contractors and acquired by individuals for residential use within the tax year. It can be transferred to the homeowner and utilized on an amended tax return or carried forward for a maximum of 20 years.

The 179D Tax Deduction – Green Building Tax Incentive

Section 179D is a tax credit provided by the federal government. It allows commercial building owners and primary designers of public building projects to be eligible for a deduction if they include specific sustainable building components in their projects.

The EPAct 179D tax deduction, also known as the Energy Policy Act, offers a sliding scale deduction ranging from $2.50 to $5.00 per square foot. 

This deduction applies to the implementation of energy systems that can reduce energy and power costs by 25% to 50% compared to buildings that meet the minimum requirements set by ASHRAE Standard 90.1-2019. 

To qualify for this deduction, retrofits must demonstrate an improvement of 25% to 50% in terms of existing building performance (EUI).

The 25C Tax Credit – Green Building Tax Incentive

For homeowners who want to improve the energy efficiency of their homes, the 25C Tax Credit is a highly beneficial incentive. 25C provides individuals with substantial financial savings by reducing their tax bill if they invest in energy-efficient upgrades.

Updated under the Inflation Reduction Act, 25C is a non-refundable credit that aims to promote energy efficiency. It helps homeowners lessen their tax burden by installing qualifying upgrades like insulation, door and window sealing, electrical improvements, and more.

Previously, the credit was limited to $500. However, starting in 2023 and continuing until 2032, the credit has been increased to 30% of the total installation costs. So homeowners can now receive up to 30% of their expenses back, potentially amounting to annual tax credits of up to $3200, depending on the extent of their upgrades.

Are you currently involved in the construction or renovation of a building? 

If you are, you will be directly affected by green building tax incentives. 

Your project has the potential to qualify for significant tax credits amounting to thousands of dollars. For instance, if your single-family or manufactured home meets ENERGY STAR requirements, you could be eligible for a tax credit of $2,500. If your home is certified as a DOE Zero Energy Ready Home (ZERH), you may qualify for an even higher tax credit of $5,000.
