The EDD collects more than $100 billion a year in payroll taxes from California’s 1.6 million employers — and its audit program tests worker classification over a standard 12-quarter window, stacking UI, ETT, SDI, and PIT assessments plus penalties when it reclassifies workers.
California doesn’t publish audit-count dashboards the way the IRS does, so this page assembles what the state does publish — collections scale, program structure, and rates — with the enforcement patterns we see representing employers, labeled as exactly that.
The scale of EDD enforcement
- Over $105 billion collected in a recent calendar year in payroll taxes, penalties, and interest (per EDD tax branch reporting)
- 1.6 million+ employers filing quarterly; 18.5 million workers covered
- Standard audit window: 12 quarters; unregistered employers: up to 8 years
What a reclassification costs in 2026
| Component | 2026 basis |
|---|---|
| Unemployment Insurance (UI) | 1.5%–6.2% (Schedule F+) on first $7,000 per worker; new employers 3.4% |
| Employment Training Tax (ETT) | 0.1% on first $7,000 |
| State Disability Insurance (SDI) | 1.3% — no wage cap since 2024 |
| PIT withholding | Assessed on reclassified wages |
| Penalties & interest | Stacked on all of the above |
What we see in practice
Three patterns from the defense side, offered as experience rather than state statistics: worker-classification disputes drive the overwhelming majority of audits; the single most common trigger is a former contractor filing an unemployment claim; and audits that begin as one worker’s status routinely expand to every similarly-situated worker across all twelve quarters. The audit process chapter walks the examination step by step; EDD audit defense covers representation; and for the broader payroll-tax problem — assessments, personal liability, resolution — see the California payroll tax attorney overview.
Frequently asked questions
How many employers does the EDD oversee?
More than 1.6 million California employers, covering over 18 million workers. The EDD’s Tax Branch collects over $100 billion a year in payroll taxes — it is one of the largest tax collection agencies in the country by dollars.
How far back does an EDD audit go?
The standard audit covers the twelve most recently completed calendar quarters — three years. If required returns were never filed, the reach extends to eight years, and there is no penalty ceiling for fraud.
What does an EDD assessment actually include?
Every reclassified worker triggers stacked assessments: Unemployment Insurance, Employment Training Tax, State Disability Insurance (1.3% in 2026, no wage cap), and Personal Income Tax withholding — plus penalties and interest on all of it.
Can the EDD hold owners personally liable?
Yes. CUIC § 1735 allows the EDD to assess responsible individuals — officers, owners, anyone controlling payments — personally for a business’s unpaid payroll taxes once the entity can’t or won’t pay.
