Key Takeaways

Energy tax credits offer businesses valuable financial incentives for investing in energy efficiency and renewable energy projects. By taking advantage of federal, state, and local programs, companies can reduce their tax liability while lowering long-term energy costs and improving sustainability. Understanding which credits apply can help businesses maximize savings and make smarter energy investments.

-Unlike deductions, tax credits directly reduce a business’s tax liability when they invest in qualifying energy-efficient technologies or renewable systems.

-Common incentives include the Investment Tax Credit (ITC), Production Tax Credit (PTC), 179D Commercial Buildings Deduction, and the R&D Tax Credit for sustainability innovation.

-Businesses may receive credits or deductions for installing renewable energy systems, improving HVAC and lighting efficiency, or implementing other sustainable technologies.

-Companies can pair tax credits with utility rebates, financing programs, or state incentives to further reduce project costs and improve ROI.

What Are Energy Tax Credits for Businesses?

Energy tax credits allow businesses to reduce their tax liability for installing or improving their current energy-efficient equipment. Credits cut the amount owed in taxes, unlike deductions, which lower taxable income. Companies become eligible by investing in sustainable systems and renewable technologies, like solar panels, HVAC systems, and LED smart lighting. Tax credits are available at the local, state, and federal levels, making them widely available to most businesses. To qualify, you must meet the proper performance or certification standards.

Which Federal Energy Tax Credits Are Available?

There are many different types of federal energy tax credits, deductions, and incentives for businesses to choose from. The main programs include: the Business Energy Investment Tax Credit (ITC), the Energy-Efficient Commercial Buildings Deduction (179D), the Renewable Energy Production Tax Credit (PTC), and the Research and Development (R&D) Tax Credit. Each program is responsible for a different aspect of sustainability, from directly generating renewable energy to improving the overall efficiency of buildings to advancing green technologies.   

What each federal tax credit accomplishes: 

  • Energy-Efficient Commercial Buildings Deduction (179D) – Designed for commercial building owners and tenants, this deduction encourages energy-efficient upgrades of HVAC and water systems, lighting fixtures, and building envelopes.  
  • Research and Development Tax Credit (R&D) – This credit pushes innovation forward, providing tax relief to those who are researching how to improve energy efficiency and sustainability processes.  

Business Energy Investment Tax Credit (ITC)

The ITC provides businesses with a credit for investing in certain renewable energy systems such as wind, solar, geothermal, and fuel cells. The Inflation Reduction Act (IRA) has recently extended timelines for claiming this credit and expanded upon what types of technologies are eligible. These updates have opened the door for more companies to afford and benefit from sustainability upgrades.  

Energy-Efficient Commercial Buildings Deduction (179D)

179D allows tenants and building owners to deduct costs for lighting, HVAC, and building envelope upgrades. The amount of the deduction varies but can reach several dollars per square foot, making it an enticing option for businesses willing to implement these efficiency improvements and obtain the required certifications.   

Renewable Energy Production Tax Credit (PTC)

The PTC offers annual renewable energy tax credits for each kilowatt hour of green energy an organization generates and sells. It’s the perfect fit for a company that operates renewable energy systems, like solar panels, wind farms, and biomass facilities, and has the storage capacity for excess energy.  

Research and Development (R&D) Tax Credit

The R&D tax credit is offered to businesses that invest in innovative technologies and strategies to improve sustainability and efficiency. These improvements that reduce environmental impact include materials research, product design, and process optimization.

How Do Energy Tax Credits Help Small Businesses (SMBs)? 

Smaller businesses tend to lack the necessary capital to tackle sustainable energy projects. Tax credits reduce the negative effects of these higher upfront costs by offsetting expenses. Energy-efficient and sustainable upgrades, such as solar installations, LED retrofits, and HVAC updates, can lower operating costs that can then be reinvested to grow the business further.  

SMBs that lease their buildings may feel energy upgrades are out of reach or pointless. However, many business energy credits are available to tenants seeking ways to improve their systems. These incentives make it possible for a company to reduce its monthly energy bills while improving its sustainability credentials.   

An example of how tax credits benefit SMBs can be found in Maine Beer Co., a local brewery. The business was able to install a rooftop solar panel system by utilizing the federal ITC. With the help of these tax credits, Maine Beer Co. was able to greatly reduce its future energy costs while also improving its sustainability.

What Financing Options Do SMBs Have?

SMBs are able to combine tax credits with rebates, loans, or low-interest financing to reduce costs even further. By taking advantage of the multiple financing options available, organizations can significantly lower costs and reduce the amount of time needed to secure an ROI. Power purchasing agreements (PPAs) are also an option to help with financing. Your business would get the benefits that come from having cleaner energy but would not own the systems outright.

What State and Local Incentives Are Available?

There’s a wide variety of state and local incentives available to boost your business’s ROI on green energy projects. With free access to the Database of State Incentives for Renewables & Efficiency (DSIRE), your business can browse the thousands of programs across the U.S. that support efficiency upgrades and renewable investments. The database allows you to filter by state and type of efficiency or technological improvement, giving your business instant access to incentives and programs it may be eligible for. For example, in Maine, the database offers low-interest loans and property-tax exemptions through state-administered renewable energy programs. 

Another source for incentives is your utility. Many utilities provide solar energy incentives or rebates that are funded separately from state and local credit programs. For example, Oncor in Texas offers property-tax exemptions and utility rebates for businesses that install commercial-scale solar panels and storage. Many of these rebates are first-come, first-served, so it’s important to investigate options and get pre-approved as soon as possible. 

How Can Businesses Claim Energy Tax Credits?

Learn how to secure clean energy tax credits for 2025 in four simple steps.  

Step 1: Conduct an Energy Audit

Performing an energy audit can decipher and identify what types of upgrades your business is eligible to make. It also ensures compliance with credit requirements.  

Step 2: Install Qualifying Upgrades

It’s important to ensure projects meet specific efficiency or renewable generation requirements. Common examples of eligible upgrades include solar panel systems, LED lighting fixtures, and smart HVAC systems.  

Step 3: Obtain Necessary Certifications

Many renewable and energy efficiency tax credits require independent verification. Third-party or American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) certifications track energy savings and compliance.  

Step 4: File with IRS or State

Fill out and submit the appropriate IRS forms or state–specific documentation. Supplement these forms with your receipts, invoices, and certifications to ensure a smooth process.  

Documentation Requirements

It’s imperative that you keep track of your energy audits, receipts, project invoices, and ASHRAE reports, as many of these tax credits and incentives require these documents before providing the credit or benefit. Requirements may vary, which is why it’s smart to organize and keep track of everything. This will save you from having to scramble for documents when the time comes. Being properly prepared keeps your business both organized and up to date with compliance during audits. 

Key Deadlines and Timing

Some requirements and deadlines need to be met to receive clean energy tax credits. For example, to qualify, projects must usually begin construction within a “safe harbor” period. This is often achieved by investing around 5% of total costs or by starting physical work. There may also be “placed-in-service” deadlines, which means the equipment must be operating by a set time to claim the credit. These deadlines make it important to act quickly. Missing them can reduce or disqualify tax credit eligibility. Plan early and move through the process diligently to ensure your business benefits from these incentives and credits.  

What Pitfalls Should Businesses Avoid?

Companies should avoid missing certification deadlines, skipping out on IRS audits, failing to keep proper track of documents, and overclaiming credits. Although this may seem like a lot to keep track of, it can be easily managed with the proper help. Energy advisors and tax professionals are available to reduce compliance risks and strengthen the likelihood that your business receives the maximum credit utilization.

Why Act Now to Maximize Savings?

Many of these programs and energy credit opportunities are on a first-come, first-served basis thanks to evolving laws, rising costs, and routine phase-outs of offerings. Programs come and go depending on these factors, so it’s important to do the proper research and move with urgency. Acting now will help your business secure higher incentives and credits to offset project costs while also accelerating its sustainability efforts.

FAQs About Energy Tax Credits & Incentives

What is the difference between an energy tax credit and a deduction? 

Deductions lower taxable income, while energy tax credits directly reduce the amount of tax owed. Both are helpful, but tax credits tend to provide a greater financial benefit for qualifying energy investments.  

Do small businesses qualify for energy tax credits? 

Yes! Small to midsize businesses qualify for many of the same federal and state energy tax credits as large businesses. Utilize the DSIRE database to find credits and programs your company is eligible for.  

Can leased buildings or rented spaces still qualify for credits? 

Yes, under 179D, tenants who pay for and install eligible energy improvements can claim credits or deductions on HVACs, lighting fixtures, and other efficiency upgrades. Just keep in mind that it is imperative for the property owner to give permission before proceeding with these improvements. 

What documents are needed to claim energy tax credits? 

The following documents may be needed to claim energy tax credits: receipts and invoices, proof of installation documents, energy audits, ASHRAE certification reports, and IRS tax forms. By staying organized, you’ll be ready to provide anything needed to secure an energy tax credit for your business.
