California DIR Requirements​

eCPR Filing​

California requires electronic certified payroll reporting:

  2. Submit CPRs within 30 days of each pay period
  3. Upload to the DIR eCPR system

Apprenticeship Requirements​

  • Minimum ratio of apprentices required

Common Audit Findings​

  1. Wrong classification — Workers doing multiple tasks
  2. Missing fringe payments — Not making contributions
  3. Incomplete records — Missing daily time records
  4. Late filing — Not submitting within 30 days
  5. Split checks — Paying part cash to avoid taxes

Best Practices​

  1. Use software — Manual tracking is error-prone
  2. Daily time records — Don't recreate from memory
  3. Verify rates monthly — Prevailing wages change
  4. Train your foremen — They classify workers daily
  5. Audit yourself — Before the government does
