When PWA Compliance Gets Put to the Test

A certified payroll report (CPR) is prepared by the contractor. It records worker classifications, hours, wage rates and pay, and the contractor attests that the information is accurate.

That makes CPRs an essential part of the compliance record. But a report can only show what the contractor reported.

A worker omitted from a CPR cannot appear in a CPR-only review. An incorrect classification can look compliant if no one compares it with the duties the worker actually performed. A reported wage can appear correct even when the amount actually paid was not.

That is why Empact distinguishes certified payroll review from three-way verification: CPRs are cross-referenced against timesheets and proof of payment so reported workers, hours, classifications, and payments can be checked against the underlying records.

The underlying data makes the difference concrete. Across the same 18,403 contractor-weeks reviewed during the twelve months through July 2026, examples of confirmed issues include:

• 740 workers were identified in contractor timesheets but were missing from certified payroll reports.
• 5,622 apprentice hours exceeded the permitted journeyworker ratio.
• Wage and fringe underpayments included cases where the rate reported on the CPR appeared correct but the amount actually paid did not.
• Classification issues required comparing the classification reported by the contractor with the duties reflected in underlying records.

CPR review is an important first step. The problem is when the review stops there.

Together, these six checks show whether the conclusions in the final report are supported by the underlying compliance work.

If you want one place to start, start with Verify: ask for one redacted week showing the certified payroll report, timesheet, and proof-of-payment reconciliation.

The standard is not whether a provider has a dashboard. It is whether the compliance conclusions can be traced back to the evidence supporting them.

The final PWA regulations require the taxpayer claiming an increased credit amount to maintain records sufficient to establish compliance for each laborer and mechanic employed by the taxpayer, its contractors and subcontractors in the construction, alteration or repair of the facility.

The taxpayer may arrange for a third-party vendor to maintain those records, but the taxpayer remains responsible for substantiating the PWA compliance position and must be able to make the required records available to the IRS on request.

For a source-document review, that can include certified payroll, timesheets, proof of payment, wage determinations, classification support, registered apprenticeship records, and documentation showing how exceptions were corrected.

Ask the provider to show the evidence behind its conclusions. That should include the source-document reconciliation, proof that every contractor and pay period was covered, records showing how exceptions were resolved, and the documentation a buyer or counsel would receive in diligence.

The point is simple: you should not have to take the provider's word for how the compliance work was done. The record should show it.

How thoroughly payroll and source records are reviewed affects when problems are found.

For certain limited Prevailing Wage failures that are not due to intentional disregard, the $5,000-per-worker penalty payment is waived if the required correction payment is made by the last day of the first month following the end of the calendar quarter in which the failure occurred and either (1) the worker was underpaid in not more than 10% of the pay periods in which the worker was employed on the project during the calendar year, or (2) the total underpayment for that worker was not greater than 5% of the amount the worker was required to be paid. The wage difference and required interest are still owed.

Apprenticeship creates a different timing problem. If the apprentice-to-journeyworker ratio is exceeded on a day, the excess apprentice hours still count toward total labor hours but do not count as qualified apprentice hours for the labor-hours requirement. An apprentice working in excess of the permitted ratio also must be paid not less than the applicable prevailing wage rate for the work actually performed.

Finding an apprenticeship shortfall while work is underway may allow the project to adjust staffing or make additional qualified-apprentice requests. If the labor-hours or participation requirements remain unsatisfied after the work is complete, the taxpayer may need to make the applicable apprenticeship correction payment unless the Good Faith Effort Exception or another applicable rule is satisfied.

That is why high-quality compliance does more than flag exceptions. It drives issues to resolution while corrective options remain available.

For Section 48 and Section 48E investment tax credit projects covered by this article, the compliance obligations and recordkeeping can continue beyond close. Prevailing Wage requirements can apply to qualifying alteration and repair work during the five-year period beginning on the placed-in-service date. Apprenticeship requirements do not apply to alteration or repair performed after the facility is placed in service.

Routine maintenance is treated differently from alteration and repair, so the project needs a process to classify post-placed-in-service work, apply the appropriate wage requirements when they attach, and maintain the supporting record. The determination depends on the facts and circumstances of the work.

That means recordkeeping is not complete at close. The project may need the record to support post-placed-in-service work and to answer diligence or IRS examination questions years later.

Two providers can both say they manage PWA compliance. Both can collect CPRs. Both can generate reports. The quality difference becomes clear in diligence, when a buyer, counsel, underwriter, or examiner asks what was tested and requests the evidence supporting the conclusions.

A high-quality record shows the chain from requirement to evidence to resolution.

It makes missing workers and missing pay periods visible. It ties exceptions to source documentation. It documents the issue, the correction, and the evidence that closed it. And it gives an independent reviewer enough information to understand how the conclusion was reached without reconstructing the file from scratch.

That matters because the same record may later be examined during tax equity or credit-buyer diligence, insurance underwriting, or an IRS examination. Source-document verification creates a record that a third party can test; speed of reporting by itself says nothing about which records were actually examined.

The goal is not simply to ask whether a provider offers PWA compliance. Ask what evidence supports the provider's compliance conclusions.

• Can they show the source records behind their conclusions?
• Can they demonstrate complete population coverage?
• Can they show how issues were corrected?
• Can another reviewer independently validate the record later?
• Will the provider stand behind the work?

Those questions tell you far more about the quality of the compliance program than the existence of a final report.
