IRS Seeks Input on 2025 Deregulation Guidance

The IRS rarely makes headlines in clean energy boardrooms. However, when the agency actively solicits industry input on a major guidance overhaul tied to 2025 legislation and deregulation priorities, developers, EPC contractors, and project financiers should pay close attention. Tax guidance isn't bureaucratic wallpaper — it's the scaffolding that determines whether a project pencils out.

What the IRS is signaling here is a structured opportunity: submit your concerns, your edge cases, your pain points — before the rules are written in stone.

What the IRS Is Actually Doing — and Why It Matters

The IRS is in the early stages of developing its priority guidance plan, and as part of that process, it's opening the floor to public input on how 2025 law changes and deregulation priorities should be interpreted and implemented. This kind of notice-and-comment phase is standard procedure, but its timing and scope make it anything but routine.

When the IRS asks for input on deregulation guidance, the window to shape the rules is short — and the developers who show up win.

For the infrastructure and clean energy world, IRS guidance isn't abstract. It determines how tax credits are claimed, how partnership structures are validated, how depreciation schedules are applied, and how transferability provisions — a mechanism that has fundamentally changed how clean energy deals are financed — actually work in practice. Ambiguity in any of these areas doesn't just create legal exposure; it freezes capital.

The 2025 legislative environment has introduced new variables: adjustments to existing incentive structures, potential rollbacks of certain provisions, and a broader deregulatory posture from Washington that affects how agencies like the IRS interpret their own mandate. The guidance plan this process feeds into will reflect those realities — and the industry's voice, or lack of it, will show.

What This Means for Infrastructure Developers

For developers working on utility-scale solar, battery storage, data centers, or land-intensive projects, the IRS guidance cycle is a critical variable in project underwriting. When rules are clear, lenders lend, and equity investors invest. When they're murky, deals stall — sometimes for months.

Deregulation, in principle, should reduce compliance friction. Fewer prescriptive requirements, simplified safe harbors, and more flexible treatment of project structures. But deregulation without clear guidance is its own kind of chaos. A developer who builds a project assuming a particular tax treatment is available — only to find out the IRS interprets the post-2025 rules differently — faces a capital stack problem that no amount of engineering excellence can fix.

The opportunity here isn't just to adapt to new rules. It's to help write them.

Infrastructure developers with active portfolios and legal teams should be preparing substantive comments for the IRS input process. This means identifying the specific provisions that create uncertainty in their deal structures, documenting the compliance burden of existing requirements they'd like simplified, and proposing clear, administrable alternatives. Trade associations — including those representing solar developers, storage integrators, and data center operators — typically coordinate comment campaigns for exactly this reason. If your organization isn't already engaged with one, now is the time.

From a project timeline perspective, clarity in guidance can compress the pre-development phase significantly. Projects that might otherwise sit in legal review waiting for a private letter ruling or technical advice memorandum could proceed with more confidence under a well-drafted safe harbor. That's not a minor efficiency gain — for a 200 MW solar project, a two-month delay in financial close can cost millions in carry costs alone.

Clean Energy Implications: Opportunity and Caution in Equal Measure

Solar and battery storage developers have more riding on this guidance cycle than almost any other sector. The past several years of incentive expansion — particularly the transferability and direct pay provisions that made tax credits accessible to a much broader pool of investors — created a financing ecosystem that is genuinely fragile in the face of regulatory uncertainty.

The potential benefits of deregulatory guidance are real. Streamlined rules around domestic content bonus credits, clearer pathways for standalone storage to qualify for investment tax credits, and simplified prevailing wage and apprenticeship documentation requirements would all accelerate deployment. These aren't marginal improvements — they're the difference between a project moving forward in 2026 or sitting on the shelf.

But the risks deserve equal attention. A deregulatory posture at the IRS level doesn't guarantee favorable outcomes for clean energy — it depends entirely on how that posture is applied.

Consider the domestic content bonus credit: deregulation could mean simplified compliance pathways, but it could also mean reduced enforcement of the requirements that protect domestic manufacturers — creating a race to the bottom that ultimately undermines the policy goal. Similarly, looser guidance around prevailing wage requirements could expose developers to retroactive credit recapture risk if the pendulum swings back in a future administration.

The clean energy finance community has learned, sometimes painfully, that tax incentive structures are only as valuable as the guidance that makes them bankable. Every institutional tax equity investor has a legal team that reads IRS guidance carefully before committing capital. Vague or incomplete guidance doesn't just slow projects — it reprices risk across entire portfolios.

Practical Advice for EPC Contractors and Project Tenants

EPC contractors occupy an interesting position in this regulatory moment. They're not the direct beneficiaries of tax incentives — that flows to the project owner — but they bear real exposure when guidance changes mid-project. Fixed-price contracts that were priced assuming a particular regulatory environment can become loss leaders if compliance requirements shift.

The most important thing EPC contractors can do right now is build regulatory change language into their contract templates. Force majeure and change-in-law provisions should explicitly address IRS guidance changes, not just permit-level regulatory shifts. If a project's economics depend on a specific tax credit structure, that dependency should be surfaced and allocated in the contract — not buried in assumptions.

For tenants in energy projects — particularly corporate offtakers signing long-term power purchase agreements — the IRS guidance cycle affects pricing indirectly but meaningfully. If the tax equity market reprices risk because of regulatory uncertainty, that cost flows downstream into PPA rates. Sophisticated corporate buyers should be tracking this process and engaging with their developer counterparties about how guidance risk is being managed.

On the due diligence side, any infrastructure transaction closing in 2026 should include a specific IRS guidance risk memo — not just a general tax opinion. Counsel should be assessing which aspects of the deal structure are sensitive to the guidance plan outcome and what contingencies exist if the rules land differently than expected.

What Comes After 2025: Reading the Regulatory Trajectory

The IRS guidance process underway now will set the tone for energy regulation changes well into the late 2020s. A few trends are worth watching.

First, the deregulatory posture in Washington is unlikely to be uniform across all provisions. Incentives tied to domestic manufacturing and job creation have bipartisan support in ways that purely environmental provisions do not. Expect guidance to reflect that political reality — some areas will see genuine simplification, while others will see heightened scrutiny.

Second, the transferability market — still relatively young, having only been authorized a few years ago — needs durable guidance to mature. Buyers and sellers of tax credits are operating on thin interpretive margins in some areas. The guidance plan is an opportunity to lock in clarity that allows this market to scale. If the IRS punts on key questions, expect the private letter ruling backlog to grow accordingly.

Third, state-level energy regulation is moving in its own direction, often independent of federal guidance. Developers operating across multiple jurisdictions need federal clarity precisely because it simplifies the calculus when state rules diverge. A coherent federal framework is an anchor — without it, multi-state portfolios become much harder to standardize and finance.

The infrastructure investors and clean energy developers who will be best positioned for the post-2025 regulatory environment are the ones engaging now — not waiting for final guidance to drop and then scrambling to adapt. The IRS has opened a door. The question is who walks through it.
