As taxpayers continue to pursue enhanced clean energy tax credits under the Inflation Reduction Act (IRA), many have become familiar with the prevailing wage and apprenticeship requirements that apply during project construction. What remains less understood is how prevailing wage obligations apply after a facility has been placed in service.
The IRA expressly requires prevailing wage compliance not only during construction, but also during certain post-construction activities. Specifically, taxpayers seeking enhanced credit amounts must ensure that laborers and mechanics performing “the alteration or repair of such facility” are paid prevailing wages during the applicable compliance period. (Federal Register, TD 9998)
For owners, developers, EPC contractors, and operations teams, the challenge is determining when routine operations and maintenance (O&M) activities cross the line into alteration or repair work that may trigger prevailing wage obligations.
Why This Distinction Matters
The financial consequences of getting this classification wrong can be significant. For many IRA incentives, taxpayers that satisfy the applicable prevailing wage and apprenticeship requirements can receive a credit amount that is up to five times greater than the otherwise applicable base credit.
At the same time, taxpayers that fail to satisfy prevailing wage requirements may be required to make correction payments, pay penalties, and work through statutory cure procedures to preserve eligibility for enhanced credit values.
As a result, understanding whether post-construction work constitutes routine maintenance or a covered alteration or repair is an important compliance consideration.
Some Interpretation Background Between the IRS and DBA
One of the most important observations from Treasury’s final regulations is that the agencies acknowledged the challenges of applying Davis-Bacon concepts traditionally used in federal contracting to a tax-credit framework.
In the preamble to the final regulations, Treasury and the IRS explained that they would incorporate only those Davis-Bacon requirements that are:
relevant for the purposes of section 45(b)(7)(A) and the intent of the IRA, and necessary for, and consistent with, sound tax administration.
Federal Register, TD 9998
The agencies further noted that they must:
take a reasonable approach to interpret a Code provision that references a Federal law applicable to Federal contracts.
For taxpayers and contractors, this language demonstrates that prevailing wage compliance under the IRA often requires a fact-specific analysis grounded in both IRS and Davis-Bacon principles.
What Does the IRS Mean by “Construction, Alteration, or Repair”?
The IRS has specifically addressed the question of what constitutes “construction, alteration, or repair” for purposes of the IRA prevailing wage requirements through its published guidance and FAQs.
Notably, the statute references “the construction of such facility” and “the alteration or repair of such facility.”
What the statute does not specifically reference is routine operations and maintenance. That omission is where much of the compliance analysis begins.
Operations & Maintenance vs. Alteration & Repair
Neither the IRA statute nor the IRS’s prevailing wage regulations provide an exhaustive list of activities that automatically qualify as operations and maintenance (O&M) or alteration and repair (A&R). As a result, taxpayers often look to Davis-Bacon authorities and Department of Labor guidance for interpretive context.
Importantly, the examples below are not definitive legal determinations and should not be interpreted as IRS-approved classifications. Rather, they reflect factors discussed in Department of Labor guidance that may help inform a project-specific analysis.
Activities Often Associated with Routine Maintenance
The Department of Labor has stated that:
Maintenance work that is routinely and regularly performed to keep the building or work functioning in the same condition is not considered construction.
Consistent with that principle, activities such as the following may be indicative of routine maintenance when performed to preserve existing operating conditions:
- Routine inspections and monitoring of equipment performance
- Preventive maintenance programs performed on a recurring schedule
- Cleaning and servicing activities intended to maintain existing functionality
- Minor upkeep work completed repeatedly over time as part of normal facility operations
The Department of Labor has further indicated that maintenance work is often characterized by activities that are “performed continuously/repetitively over time,” “completed comparatively quickly,” and intended to maintain a facility “in its existing condition.”
Activities That May Suggest Alteration or Repair
By contrast, Department of Labor guidance explains that:
Restoration or improvement of a facility by modifications to the facility’s components, systems, or materials is considered to be alteration or repair.
The guidance also notes that alteration or repair work will generally “improve the building or work, either by fixing something that is broken or by improving upon the building or work’s existing condition.”
Based on those principles, activities such as the following may warrant closer review:
- Major component replacement projects
- Equipment refurbishments or overhauls that restore or improve facility functionality
- Modifications to facility systems or materials intended to improve efficiency, capacity, usefulness, or performance
- Corrective work addressing specific failures, defects, or broken equipment
- Work requiring skills commonly associated with construction trades
The Department of Labor identifies additional factors suggesting alteration or repair, including whether the work:
- Corrects “individual problems or defects as separate and segregable incidents,”
- Improves a facility’s “structural strength, stability, safety, capacity, efficiency, or usefulness,” or
- Involves skills “typical of one or more construction trades.”
Important Caveat
Ultimately, neither the IRA nor current IRS guidance establishes a simple checklist for determining whether a particular activity constitutes maintenance or alteration and repair. Classification is often highly dependent on the scope, purpose, frequency, and technical nature of the work being performed. Taxpayers should evaluate significant post-construction activities based on the specific facts and circumstances of the project and should consult qualified legal, tax, and prevailing wage advisors when uncertainty exists.
Conclusion
As guidance continues to develop, taxpayers should carefully evaluate significant post-construction activities and document the basis for their classifications to help mitigate compliance risk and preserve enhanced credit eligibility.
