An EDD Notice of Assessment gives you 30 days to file a petition for reassessment with the California Unemployment Insurance Appeals Board. File it and the assessment is on hold pending a hearing before an administrative law judge. Miss it and the assessment is final — and the EDD’s collection machinery starts.
The petition itself is straightforward — a written statement of what you contest and why, filed under CUIC § 1222 — and it does not need to argue the whole case. It needs to be timely and preserve your grounds. The case that follows is more formal than people expect: an evidentiary hearing before a CUIAB ALJ, with testimony, exhibits, and a written decision, followed by an appeal to the Appeals Board itself and, after that, superior court review.
What to do with the 30 days
File early, then use the runway. The months between petition and hearing are where winning cases get built: assembling exemption and prong-C evidence for classification cases, reconciling the auditor’s wage math (EDD schedules contain arithmetic and period errors often enough to always check), and opening settlement conversations — the EDD settles, particularly where its hearing risk is real.
Personal exposure runs alongside
If the business entity cannot pay, CUIC § 1735 lets the EDD assess responsible officers and owners personally for the corporate payroll tax — the state cousin of the IRS Trust Fund Recovery Penalty. A § 1735 assessment carries its own petition rights and its own 30-day clock, and defending the entity assessment well is usually the cheapest way to never meet § 1735 at all.
Missed the deadline? A late petition can sometimes proceed on good-cause grounds, and even a final assessment leaves narrow paths — but every one of them is worse than filing on time. If the notice is in your hand, the date on it is the only fact that matters this week.
How engagements work
Many matters like this one run as a monthly flat-fee engagement: one number, agreed up front, that covers the work — agency contact, deadlines, document responses, strategy — until the matter resolves. Shorter, well-defined projects are often a one-time flat fee instead, and some matters genuinely fit hourly billing better. We will tell you which you are looking at on the first call, before you commit to anything. If you want the details first, see how we price our work.
