PWA Compliance for Subcontractors: Start Here

Your first job is to freeze the inputs

Before anyone mobilizes, get the project-specific rules in writing. Your tracker should record the exact facility, contract, wage determination and modification, approved classifications, reporting cadence, due date, apprenticeship approach, and escalation contacts.

Do not let a spreadsheet decide whether your scope is covered. Coverage and project-specific requirements belong with the taxpayer, upstream contractor, and qualified advisers.

• Confirm whether PWA applies to your scope.
• Record the exact wage determination and modification/date.
• Confirm the classifications expected for your work.
• Get the payroll format, deadline, and submission destination.
• Identify who approves corrections and apprenticeship issues.

Build a weekly control loop

The simplest useful system is a recurring sequence: collect, check, track, fix, submit, and file. It should happen every week while payroll records and project facts are still easy to reconstruct.

• Collect payroll, workforce, apprentice, and lower-tier records.
• Check completeness before reviewing wage and classification details.
• Track apprentice hours, daily ratio evidence, participation, and written requests separately.
• Return incomplete packages with a dated deficiency list.
• Save the exact package submitted and proof of delivery or acceptance.

Understand the three apprenticeship components

IRS guidance describes the apprenticeship requirements as three separate components: a labor-hours requirement, a daily ratio requirement, and a participation requirement. One overall percentage does not answer all three questions.

The applicable labor-hours percentage is tied to when construction began: 10% before 2023, 12.5% during 2023, and 15% in 2024 or later. The daily ratio comes from the registered apprenticeship program. The participation component applies when a taxpayer, contractor, or subcontractor employs four or more individuals during covered work.

Escalate exceptions; do not invent answers

Preserve the facts, assign an owner, set a correction date, and keep the original record next to every revision. The subcontractor's operational role is to surface the issue early and create a clean evidence trail.

• A classification is missing from the wage determination.
• A worker performs more than one trade during the same pay period.
• Payroll cannot explain a fringe-benefit credit.
• An apprentice is not clearly registered in a qualifying program.
• The daily apprentice-to-journeyworker ratio is unknown.
• A lower-tier company has missed multiple payroll weeks.
