What is prevailing wage compliance for IRA tax credits?

Under the Inflation Reduction Act, clean energy projects must pay workers prevailing wages and meet apprenticeship requirements to qualify for enhanced tax credits. Non-compliance triggers fines of $5,000 or more per worker per violation, and puts the credit at risk. Vindexa checks every payroll so anomalies are caught and cured within the IRS cure window.

How is Vindexa different from a compliance consultant?

Consultants typically deliver findings weeks or months after the fact — often after cure windows have already closed. Vindexa checks every payroll the week it lands, so anomalies are fixed while there is still time. We augment what consulting teams do well with the speed and granularity that only continuous checking provides.

Who is Vindexa built for?

Vindexa is built for clean energy developers, EPCs, and their compliance and finance teams: the VP of Tax or CFO who signs the return, and the Head of Compliance who manages day-to-day remediation. We do the work, so teams without dedicated compliance staff get the same outcome.

How long does it take to get started?

Most customers are live within 15–20 days. Results are typically visible within one to two payroll cycles.

You build the projects. We make the credits stick.

Continuous prevailing-wage and apprenticeship verification for IRA tax credits. Audit-ready, by default.

One outcome covers both halves. We take on the work you budget for today, and drive the half you can’t see as close to zero as the evidence allows.

Every payroll, checked into one record.

Payroll from the EPC’s own crews and every subcontractor below them comes to us. We check each line against the rate, the fringe, and the apprentice hours. When something is off, we fix it inside the cure window. Every line lands in The File.

Found the week it happens. Not at year end, when a $5,000 penalty per worker is already owed.

One file. Always current. Ready when your tax team needs it.

The File is what your VP of Tax signs. Cross-checked against every payroll and every rate, built as the work happens. Not assembled the week before a deadline.

Built from: Every payroll, every project
Updated: Every payroll cycle
Defensible to: IRS · DOL · Tax equity

Built for the people who sign.

The VP of Tax

Signs the return under penalties of perjury without living in the data. Needs a record to point to, not a consultant’s report that arrived after the deadline.

The File, current every payroll.
Cross-checked documentation for every project.
The evidence behind the signature.

The Head of Compliance

Lives in the EPC back-and-forth, chasing certified payrolls and tracking corrections to the penny. Needs the friction absorbed, not added to.

Anomalies caught inside the cure window.
Data collection and gap-chasing done for you.
Remediation followed through to closure.

Built inside one of the most complex clean-energy portfolios in the country.

Two core problems, each hard in its own way. Violations hide in dense documents and in how those documents interact. Clean data has to be chased down and verified. Vindexa was built to handle both.
