How to Read Your DE 2088: California Notice of Contribution Rates

The DE 2088 is the Notice of Contribution Rates and Statement of UI Reserve Account that California’s Employment Development Department mails to every registered employer each year, showing your Unemployment Insurance and Employment Training Tax rates for the coming calendar year.1Employment Development Department. California System of Experience Rating EDD mailed the 2026 edition by December 31, 2025, so most employers should already have it in hand.2Employment Development Department. California Employer News and Updates You don’t fill it out or send it back. You read it, load the new rates into payroll, and protest anything that looks wrong before the deadline printed on the notice.

What’s on the Notice

The DE 2088 puts your UI and ETT rates on a single page along with the account data EDD used to calculate them.3Employment Development Department. Contribution Rates, Withholding Schedules, and Meals and Lodging Values You’ll see:1Employment Development Department. California System of Experience Rating

  • Your assigned UI contribution rate, applied to each employee’s taxable wages for the year.
  • Your Employment Training Tax rate, a smaller separate rate that funds workforce training.
  • The annual taxable wage limit — the per-employee wage cap above which UI and ETT contributions stop for the year.
  • The statewide UI rate schedule in effect for the year.
  • An itemized breakdown of your UI reserve account, including the factors used to compute your reserve account ratio.

How Your Rate Was Calculated

California assigns UI rates through an experience rating system. Employers whose former workers have drawn more benefits pay higher rates; employers with fewer benefit charges pay less.1Employment Development Department. California System of Experience Rating

Your UI reserve account tracks the running balance between contributions you’ve paid in and benefits charged against you when former employees collect. EDD turns those figures into a reserve account ratio and maps the ratio to a specific rate on the year’s schedule. Both numbers appear on the DE 2088, so you can trace the calculation.

Which schedule applies depends on the health of the state’s UI trust fund. A healthy fund triggers a lower-cost schedule for everyone; a depleted fund triggers a higher one. Your rate can climb from one year to the next even when your own claims history hasn’t changed.

What to Do When It Arrives

EDD suggests three steps.2Employment Development Department. California Employer News and Updates

  • Review your UI and ETT rates and scan the reserve account activity for charges you don’t recognize.
  • Enter the new rates in your payroll tax software, or send them to whoever runs your payroll so withholding and deposits are correct starting with the first pay period of the year.
  • Read the protest information printed on the notice and note the deadline.

Get the rate into payroll promptly. UI contributions are calculated per employee per quarter, and running even one quarter on last year’s rate can produce underpayment penalties or overpayments you’ll have to reconcile later.

Protesting a Rate You Think Is Wrong

If the rates on your DE 2088 look incorrect, you can file a protest. The notice itself carries the specifics on your protest rights and the deadline.2Employment Development Department. California Employer News and Updates

Employers most often protest for reasons like these:

  • A former employee who quit voluntarily or was fired for misconduct collected benefits that were charged to your account.
  • The reserve account balance doesn’t reflect contributions you actually paid.
  • Benefits for a worker who held multiple jobs were charged entirely to your account instead of being split among employers. This comes up often with staffing agencies.

The itemized reserve account breakdown on the notice is where these errors show up. Benefit charges you don’t challenge become permanent entries in your reserve account and keep affecting your rate in future years.

Keep the Notice

California requires employers to keep records related to federal and state payroll taxes for at least four years.4California Tax Service Center. Staying on Track, Keeping Good Business Records Your DE 2088 belongs in that file. It documents the rate you were supposed to apply each year, which is what EDD will ask for if your deposits are ever audited. Holding on to prior notices also makes it easier to see trends in your reserve account and catch unexpected benefit charges before they compound.

Not to Be Confused With Form DE 2063

The DE 2088 is sometimes mixed up with the Notice of Reduced Earnings, Form DE 2063. They are unrelated. The DE 2063 is the form an employer completes to certify that an employee’s hours have been cut due to lack of work, so the employee can file a partial unemployment claim.5Employment Development Department. Unemployment Insurance – Forms and Publications Employers issue one for each payroll week the employee works reduced hours, and the employee uses it to claim partial UI benefits.6Employment Development Department. Notice of Reduced Earnings If that’s the form you were looking for, it’s available on EDD’s Forms and Publications page.
