1. What is State Tax?

State tax is a tax levied by individual states on income earned within that state. The amount varies by state and is calculated based on taxable income and the state's tax rate.

2. How Does the Calculator Work?

The calculator uses the state tax formula:

Where:

• \( Taxable\ Income \) — Income subject to state taxation ($)
• \( State\ Tax\ Rate \) — State's tax rate (decimal)

Explanation: The calculation multiplies your taxable income by your state's tax rate to determine how much you owe in state taxes.

3. Importance of State Tax Calculation

Details: Accurate state tax calculation helps with financial planning, budgeting, and ensuring you pay the correct amount of taxes to avoid penalties or overpayment.

4. Using the Calculator

Tips: Enter your taxable income in dollars and your state's tax rate as a decimal (e.g., 5% = 0.05). Both values must be positive numbers.
