W-2 Information: Understanding Your W-2

  • General Information

The Form W-2 reflects wages paid by warrants/direct deposit payments that were issued to you during the tax year (January 1 through December 31), regardless of the pay period in which you earned the wages.

Form W-2 contains all wages and tax information for you regardless of the number of State of California agencies/CSU campuses for which you worked during the tax year.

The year-to-date gross on your final paycheck stub (earnings statement/direct deposit advice) may not agree with Box 1 (Wages, Tips, Other Compensation) of your W-2, due to the following items:

  • Retirement
  • Employee paid health
  • Tax Shelter Annuity (TSA) Contributions
  • Deferred Compensation/Savings Plus Program Contributions
  • Dependent Care Account (DCA)
  • Health Care Reimbursement Account (HCRA)
  • Pre-tax Parking Deduction
  • Accounts Receivable Deductions
  • Non-Uniformed State Payroll System (USPS) Adjustments (Including taxable fringe benefits)

  • Distribution of W-2 Form
The W-2 form is issued once a year and is mailed by the State Controller's Office directly to the address you have on file with Payroll Services. W-2's are mailed to your home address normally by January 20th of each year. Undeliverable W-2 forms are returned to Payroll Services.
