Withholding Recalculation

Subtract eligible payroll deductions from regular federal wages:

Federal Regular Wages= Salary - Medical - 401(k) - FSA/HSA

Calculate regular federal withholding after bracket amounts and credits:

Federal Regular Withholding= Bracket Base + Marginal Amount - Eligible‑Child Credit

Subtract FICA-exempt payroll deductions from gross wages:

FICA Wages=Gross - Medical - FSA/HSA

Apply the Social Security rate to wages up to the annual wage base:

Social Security Withholding= MIN(FICA Wages, 2026 Wage Base) × 6.2%

Subtract SDI-exempt payroll deductions from gross wages:

California SDI Wages= Gross - Medical - FSA
