1. What California State Withholding Means
There is no single flat percentage of California state tax that "should" be withheld from your paycheck. The exact dollar amount depends on your wage bracket, pay frequency, filing status, and the number of allowances you claim on California Form DE 4.
State tax withholding is an advance installment payment of your estimated California Personal Income Tax (PIT) remitted directly by your employer to the Employment Development Department (EDD) and Franchise Tax Board (FTB). When you file your California resident tax return (Form 540) in the spring, your actual tax liability is reconciled against your withholdings:
- If your employer withheld too much, you receive a state tax refund.
- If too little was withheld, you owe a tax balance and potential underpayment penalties.
