FICA (Social Security & Medicare): Federal law requires 6.2% for Social Security (up to $168,600 in 2024) and 1.45% for Medicare.CA SDI: California State Disability Insurance. For 2024, the rate is 1.1%, and notably, the taxable wage limit has been removed, meaning it applies to all earnings.Federal Income Tax: Based on your W-4 filing and IRS tax brackets.California State Income Tax: Ranges from 1% to 13.3% depending on your income level.
