How this calculator works
California PIT uses the annualized Method B calculation permitted by EDD, with the 2026 low-income exemption, deduction, allowance credit and rate tables. SDI is calculated separately at 1.3% of covered wages with no wage cap. Married dual-income or multiple-employer withholding uses the Single option in the California filing field.
Example calculation
EDD’s 2026 annualized example uses $57,000 annual wages, monthly pay, Married status and four regular California allowances. It produces approximately $7.17 California PIT per month. On $4,750 of SDI-covered monthly wages, SDI is $61.75 before considering other deductions.
2026 methodology & assumptions
For regular U.S. employee wages with a 2020-or-later W-4. This estimate uses 52 weekly, 26 biweekly, 24 semi-monthly or 12 monthly pay periods. Federal withholding follows IRS Publication 15-T Worksheet 1A. Amounts are rounded to cents.
Social Security uses a $184,500 wage limit and 6.2% employee rate; Medicare uses 1.45%. Additional Medicare withholding is 0.9% on wages above $200,000 paid by the same employer, regardless of filing status. Enter year-to-date taxable wages before this paycheck to model those thresholds.
California uses EDD Method B annualization, including DE 4 allowances and 1.3% uncapped SDI. Period-specific tables may differ slightly because of rounding. Supplemental wages, nonresident-alien adjustments, self-employment tax, local taxes, special exemptions, and multi-state allocation are not automatically modeled. Overtime is not automatically treated as tax-free.
Frequently asked questions
Are W-4 credits the same as California allowances?
No. Federal Step 3 is an annual dollar amount. California DE 4 regular and additional estimated-deduction allowances are separate whole-number inputs.
Does this determine California overtime eligibility?
No. Enter the regular and overtime hours and rate that apply to your situation. Daily overtime, double time, exemptions and special wage rules require separate review.
