Form 7220, Prevailing Wage and Apprenticeship (PWA) Verification and Corrections, is the IRS form used to document that a clean energy project met labor standards required under the Inflation Reduction Act and to calculate any correction payments or penalties if it didn't. Meeting these requirements can multiply certain credits by five times the base rate, so the form has significant financial stakes attached to it.
What Is Form 7220 Used For?
Form 7220 is filed with your tax return, one per qualifying facility, to demonstrate that prevailing wage and apprenticeship (PWA) requirements were satisfied during construction, alteration, or repair of a clean energy project. It's also used to calculate any penalty or correction payments if those requirements weren't fully met.
The IRS released the form for the first time for the 2025 tax year, so this is new ground for most filers and preparers.
Why Does Prevailing Wage and Apprenticeship Compliance Matter?
Under the Inflation Reduction Act, several clean energy tax incentives, including the investment tax credit and production tax credit, pay a base rate unless the project also satisfies PWA requirements. Projects that do satisfy them can qualify for a credit equal to five times the base amount.
That difference can be the gap between a credit that barely moves the needle and one that materially changes a project's economics.
What Happens If Prevailing Wage Requirements Aren't Met?
The IRS allows a cure. If workers were paid below the required prevailing wage rate, the taxpayer can still claim the increased credit by:
- Paying each affected worker the wage shortfall, plus interest at an elevated underpayment rate
- Paying a penalty of $5,000 per laborer or mechanic who was underpaid
If the IRS determines the failure was due to intentional disregard of the rules rather than an honest mistake, the per-worker penalty increases to $10,000.
What Happens If Apprenticeship Requirements Aren't Met?
A similar correction mechanism applies to apprenticeship shortfalls: taxpayers can cure a failure by paying a penalty of $50 for every labor hour that didn't meet the apprenticeship participation requirement. A good faith effort exception may also apply in certain circumstances, which Form 7220 has a dedicated section to document.
When Should PWA Compliance Tracking Start?
Ideally, before the first laborer or mechanic sets foot on the project. Because prevailing wage and apprenticeship data has to be tracked hour by hour and worker by worker throughout construction, trying to reconstruct it after the fact â during tax season â is where most documentation gaps and correction payments come from.
FAQ
Is Form 7220 required every year a project is under construction?
A separate Form 7220 is generally required for each facility, filed with the return on which the related credit or deduction is claimed, for each year covered by the compliance period.
Does Form 7220 replace the underlying credit form, like Form 3468 or Form 8835?
No. Form 7220 supports and verifies the PWA compliance behind the increased credit amount â it's filed alongside the primary credit form, not instead of it.
Do subcontractor payroll practices count toward compliance?
Yes. Prevailing wage requirements generally extend to laborers and mechanics employed by contractors and subcontractors on the project, not just the taxpayer's direct employees.
Is Your Project Affected?
If your business or client is claiming an energy tax credit tied to the Inflation Reduction Act's bonus rate â solar, wind, storage, or another qualifying facility â PWA compliance and Form 7220 documentation are likely part of the filing.
Getting the labor records, payroll substantiation, and correction calculations right the first time is far easier than reconstructing them under audit pressure.
