What is a California EDD payroll tax audit?

The Employment Development Department audits employers for UI, SDI, ETT, and worker classification. It is separate from the IRS and can reach back several years.

What is the EDD?

The Employment Development Department administers California's payroll tax programs, including:

  • Unemployment Insurance (UI)
  • Employment Training Tax (ETT)
  • State Disability Insurance (SDI) (employee withholding)

EDD is not the IRS. A clean federal return does not prevent an EDD audit.

Why EDD audits employers

Common reasons include:

  • Worker misclassification (1099 contractors reclassified as employees)
  • Discrepancies between DE 9 quarterly reports and wages paid
  • Referrals from other agencies or anonymous tips
  • Random selection programs

Lookback and assessments

EDD can examine multiple quarters. Assessments may include unpaid contributions, interest, and penalties. Officer liability can apply in some cases.

How this differs from income tax

EDD cares about employment status and reported wages, not whether your Schedule C deduction is allowed.

Good practices

  • Register as an employer when you hire W-2 staff
  • File DE 9 / DE 9C on time
  • Keep payroll registers that tie to quarterly filings
  • Document contractor relationships before paying 1099s
