M any entrepreneurs prioritize making their businesses environmentally friendly, but the costs can seem prohibitive. The U.S. government offers some cost-saving options to help come tax season, particularly the Internal Revenue Code (IRC) Section 179D tax deduction for business property and the IRC Section 48C tax credit for energy projects.
Here, we discuss what you can do to save money as you make your business more environmentally friendly. We cover the §179D tax deduction, the §48C tax credit, other credit options, and how they work.
Environmental Tax Deductions and Environmental Tax Credits for Businesses
The U.S. offers both environmental tax deductions and environmental tax credits for businesses. And, if you work from home, you may also qualify for additional tax credits.
The Energy Efficient Commercial Buildings Deduction (§179D Tax Deduction)
The primary environmental tax deduction for businesses is the §179D tax deduction. The deduction comes in two forms: the energy efficient commercial building property (EECBP) deduction and the energy efficient commercial building retrofit property (EEBRP) deduction. These credits may be available to businesses that place qualified commercial buildings in service and to designers of green features installed in buildings owned by certain tax-exempt entities.
General Section 179D Requirements
To qualify for the deduction, the building must:
Be located within the U.S.
Have environmentally friendly features
Those features must follow the green energy standards established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society of North America (IESNA)
Also, the environmentally friendly features must be a part of the building’s:
Interior lighting system
Heating, cooling, or ventilation system
Hot water system
Envelope (the building components that separate indoors from outdoors)
You place the property in service for tax purposes when it is available and ready for use, even if you have not yet started using it. It also must be the kind of property you can amortize, like startup and organizational costs, the cost of acquiring a lease for business property, or research and experimental expenses.
Qualified EECBP Buildings
To qualify for the EECBP deduction, you must create a plan based on the ASHRAE and IESNA green energy requirements. The plan must reduce consumption by at least 25% compared to the ASHRAE and IESNA minimums. A professional must certify that the features being installed meet that standard.
Qualified EEBRP Buildings
A building must establish a qualified retrofit plan to qualify for the EEBRP deduction. The building’s owners must have placed it in service within five years of establishing the plan.
A professional must design the retrofit plan to qualify for the deduction.
Deduction Amount
You can typically deduct the lesser of the cost of the installed property or an amount calculated as follows:
For a building with 25% energy savings, $0.50 per square foot
Plus an extra $0.02 per square foot above 25% savings
Up to $1.00 per square foot for 50% savings
If you deducted building expenses in the previous three to four years, subtract the amount of those deductions before calculating your current deduction.

The Advanced Energy Project Credit (Section 48C Tax Credit)
The advanced energy project credit applies to entities that invest in qualifying advanced energy products. Qualifying advanced energy products include:
Clean Energy Manufacturing and Recycling Projects
Industrial Decarbonization Projects (formerly named Greenhouse Gas Emissions Reduction Projects)
Critical Materials Projects
Unlike most tax credits, you apply for the §48C tax credit through the U.S. Department of Energy (DOE).
Clean Energy Manufacturing and Recycling Projects
Clean Energy Manufacturing and Recycling Projects establish, expand, or reequip facilities for the manufacture of:
Property or equipment designed to produce solar, wind, geothermal, or other renewable energy sources
Fuel cells, microturbines, or energy storage for electric or hybrid-electric vehicles
Electric grids to store or transport renewable energy
Property or equipment designed to capture carbon dioxide
Property or equipment refining or blending renewable energy
Energy conservation technologies
Electric motor vehicles and their components
Projects intended to refine or blend nonrenewable fuels do not qualify.
Industrial Decarbonization Projects
Industrial Decarbonization Projects involve retrofitting industrial or manufacturing facilities, especially those related to:
Cement
Iron
Steel
Aluminum
Various chemicals
The retrofit must be designed to reduce emissions of greenhouse gasses by 20% or more to qualify.
Critical Materials Projects
Critical materials projects establish, expand, or reequip industrial facilities for the processing, refining, or recycling of critical materials. Critical materials include the following items that have a high risk of supply chain disruptions and serve an essential function in the energy technology process:
Non-fuel minerals
Elements
Substances
Critical minerals
The following are not critical minerals:
Fuel-related minerals
Water, ice, and snow
Many sand, gravel, stone, pumice, cinders, and clay varieties
Critical minerals typically include rare earth elements.
Credit Amount
The advanced energy project credit allows you to claim 30% of the investment costs for projects that meet prevailing wage and apprenticeship requirements. For projects that do not meet those requirements, you can claim 6% of your expenses.
You meet the prevailing wage requirements if you pay your workers no less than the amount usually paid for the type of work in the area, as determined by the U.S. Department of Labor (DOL). You meet the apprenticeship requirements if you employ apprentices from registered programs for a specified number of hours—and those hour requirements vary.
Applying for the Credit
You apply for the credit through the DOE’s §48C Portal. When you apply, you must submit:
A narrative description of the project and a workforce and community engagement plan
A §48C Application Data Sheet
A business entity certification
Templates and forms are available through the §48C Portal.
The credit does not follow the typical tax timeline. The DOE publishes application deadlines each year. For example, in 2024, the application period opened on August 29 and closed on October 18.
When evaluating applications, the DOE considers the project’s:
Commercial viability
Domestic job creation potential
Impact on air pollutants and greenhouse gasses
Potential for technological innovation and commercial deployment
Energy generation or storage costs or reductions to energy consumption or greenhouse gas emissions
Expected timeline
The DOE selects qualifying projects based on these factors.

Green Tax Credits for Business at Home
If you work from home, you may be able to claim the energy efficient home improvement credit, the residential clean energy credit, or both. Although not specifically green tax credits for business expenses, these credits can apply if you use your home as your business. You can apply the credit to a home office based on the percentage of the home that qualifies as your office. You can take full credit if the business uses 20% or less of the home. If it uses more than 20%, you can claim a share based on what percentage of the home you use for non-business purposes.
The Energy Efficient Home Improvement Credit
The energy efficient home improvement credit applies to qualifying expenditures related to an existing home, including additions or renovations involving:
Qualified energy efficiency improvements (for example, improvements to exterior doors, windows, skylights, insulation, and air sealing materials or systems)
Residential energy property expenses (for example, costs related to central air conditioners, natural gas, propane or oil water heaters, propane or oil furnaces, and hot water boilers)
Biomass stoves and boilers, heat pumps, and water heaters
Home energy audits of a main home
The credit allows you to claim up to $2,000 for qualified heat pumps, biomass stoves, or biomass boilers and $1,200 for energy property costs and certain energy efficient home improvements.
The Residential Clean Energy Credit
The residential clean energy credit applies to new, qualified clean energy equipment installed in a U.S. home between 2022 and 2033. Qualified clean energy equipment may include:
Solar electric panels
Solar water heaters
Wind turbines
Geothermal heat pumps
Fuel cells
Battery storage technology
You can claim up to 30% of the costs of these projects.
The U.S. government offers cost-saving options, like the §179D tax deduction and the §48C tax credit, to help businesses go green.
Claiming Your Green Tax Deductions and Credits
The U.S. government offers green tax credits and deductions to help businesses become and stay environmentally friendly. Claiming these credits can be complicated, especially the advanced energy project credit, which requires an application with the DOE. A lawyer or certified public accountant specializing in green energy can help you apply.
