TL;DR

Yes, C-corporations can use Renewable Energy Tax Credits (RETCs) to reduce their federal tax liability — and often by up to 75% in a given year. These credits are transferable, meaning C-corps can purchase them without developing energy projects themselves. This blog outlines eligibility, mechanics, compliance, and how B10 Energy simplifies the process.

Why RETCs Matter More Than Ever for Corporations

If you're a CFO, controller, or tax advisor for a C-corporation, you're likely on the lookout for strategic, IRS-compliant ways to reduce your company’s tax burden. One of the most powerful — yet still underutilized — tools available today is the Renewable Energy Tax Credit (RETC).

The short answer: Yes, C-corporations can absolutely use RETCs. And for many, they represent one of the smartest and cleanest tax planning opportunities on the table in 2025.

C-corps face a unique challenge: a fixed Federal corporate tax rate (currently 21%) and fewer tax reduction options than pass-through entities. As margins tighten and ESG expectations increase, C-corporations are looking for strategies that do more than just lower taxes — they need solutions that align with long-term value, stakeholder trust, and public accountability.

That’s where RETCs shine.

Thanks to updates from the Inflation Reduction Act, many energy credits are now transferable, opening the door for C-corps to purchase and apply them to their own tax liabilities — without needing to develop or operate a renewable energy project themselves.

Who Qualifies to Use RETCs?

RETCs can be used by taxpayers who meet the following criteria:

  • The entity must be taxed as a C-corporation (not a pass-through like an S-corp or LLC).

  • The taxpayer must have federal income tax liability (i.e., taxes owed).

  • The credits must be tied to a qualified, IRS-approved renewable energy project.

  • The purchasing entity must receive the correct documentation and follow IRS transfer procedures.

That last part is important: the IRS is increasingly focused on compliance in the credit transfer market. Working with a vetted credit provider like B10 Energy ensures that everything — from eligibility to documentation — is handled securely and correctly.

The Financial Benefits: Why C-Corps Should Pay Attention

Offset Up to 75% of Federal Income Taxes

RETCs allow you to offset up to 75% of your federal income tax liability in a given year. That’s not a deduction — it’s a direct, dollar-for-dollar reduction in taxes owed.

For corporations with seven- or eight-figure liabilities, that’s a serious cash preservation tool.

Improve After-Tax Profitability

Because the savings are realized as a credit (not a deferral or deduction), RETCs improve your actual after-tax earnings — a metric that’s meaningful to boards, shareholders, and performance-based bonus structures.

Compliant and Transparent

Unlike some advanced tax strategies that walk a fine line with the IRS, RETCs are clearly sanctioned in the tax code. When properly sourced and documented, they represent one of the lowest-risk, highest-impact strategies available.

How the RETC Process Works for C-Corporations

At B10 Energy, we guide clients through a streamlined process to ensure their credits are sourced properly, documented fully, and applied efficiently. Here’s how it works:

Step 1: Confirm Eligibility

We help you verify your entity type, income structure, and filing method to ensure you qualify under current IRS rules. (We also help clarify edge cases, like corporations with pass-through subsidiaries.)

Step 2: Evaluate Tax Liability

Working alongside your internal team or CPA, we assess your annual tax liability and determine how much of that can be offset using RETCs — typically up to 75%. This step is critical to ensure you purchase only what you need and can use.

Step 3: Source and Secure Credits

We connect you with verified, IRS-compliant renewable energy credits from eligible developers. These are thoroughly vetted for legitimacy, project certification, and transferability.

You’ll receive:

  • Chain-of-title documentation

  • IRS-required transfer forms

  • Full audit-ready records

Step 4: Integrate with Financial and ESG Strategy

Beyond tax savings, RETCs help corporations tell a stronger story. We support your sustainability, ESG, and investor relations teams with clear data on the impact your credit purchase supports — from megawatts of clean power to carbon reduction equivalency.

How RETCs Support ESG and CSR Goals

The financial case for RETCs is strong, but the strategic upside goes further. Many companies today are under pressure to deliver on ESG commitments, and RETCs provide a clean, quantifiable way to do that.

Environmental

Each credit purchased is tied to a real renewable energy project — solar, wind, geothermal, or other technologies. That means your dollars are directly funding cleaner power.

Social & Governance

Transparent, measurable credit usage supports your CSR reporting, enhances your credibility with investors, and signals responsible corporate governance.

In short: RETCs offer a rare opportunity to meet your financial objectives while advancing corporate sustainability.

What RETCs Are (and Aren’t)

There’s often confusion around how energy credits work — and how they compare to other tax incentives. Let’s clarify:

Common Misconceptions About RETCs

Let’s bust a few myths that often stop companies from taking advantage:

  • “Aren’t these only for energy companies?”
    Not anymore. With transferability, you can buy credits without owning or developing a project.

  • “This sounds too complicated.”
    It’s not. When you work with a firm like B10 Energy, the complexity is on us — not you.

  • “We already use other tax credits.”
    Great! RETCs can often stack with other strategies. With the help of B10 Energy, your CPA can help optimize the overall mix.

  • “We missed the window this year.”
    Not necessarily — RETC purchases can often be finalized as part of year-end planning or Q1 filing strategy. Reach out early to explore your options.

A Low-Risk, High-Impact Tool for 2025 and Beyond

C-corporations have a narrow set of truly effective tax tools that are both low-risk and high-impact. RETCs sit at the top of that list — offering predictable savings, measurable environmental benefit, and strong alignment with shareholder values.

The combination of:

  • IRS-compliant structure

  • Transferability under current law

  • Transparent sourcing

  • Support for ESG and CSR reporting

…makes RETCs a strategic fit for many B10 clients, whether you're a CFO navigating tax exposure or a sustainability lead building your company’s impact profile.

Conclusion: Yes, You Can — And You Should

C-corporations can absolutely use renewable energy tax credits — and with transferability in place, there’s no reason not to. You don’t need to be in the energy sector. You don’t need to manage a project. You just need to be smart about sourcing, compliant in application, and strategic in integration.

At B10 Energy, we help you do exactly that — from credit acquisition to IRS-ready documentation, all with a focus on simplicity and transparency.
