1. What is Bonus Tax in California?

In California, bonuses are considered supplemental wages and are taxed differently than regular wages. They are subject to both federal supplemental tax rates (typically 22%) and California state income tax.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Bonus \) — The bonus amount in dollars
• \( Federal\_rate \) — Federal supplemental tax rate (typically 0.22)
• \( CA\_rate \) — California state tax rate (varies by income)

Explanation: The calculator multiplies your bonus by the sum of federal and state tax rates to determine the total tax withholding.

3. Importance of Bonus Tax Calculation

Details: Understanding bonus taxation helps with financial planning and ensures you're not surprised by a smaller-than-expected net bonus amount.

4. Using the Calculator

Tips: Enter your bonus amount, federal tax rate (default is 0.22), and your California tax rate. All values must be valid (bonus > 0, rates between 0-1).
