1. What is State Sales Tax?

State sales tax is a consumption tax imposed by state governments on retail sales of goods and services. The 2025 rates vary by state and sometimes by locality within states.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Price \) — The pre-tax price of the item or service (USD)
• \( State\ Rate\ 2025 \) — The applicable state sales tax rate for 2025 (as decimal)

Explanation: The tax amount is calculated by multiplying the item's price by the state's sales tax rate.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is essential for businesses to comply with tax laws, for consumers to understand total costs, and for financial planning.

4. Using the Calculator

Tips: Enter the item's price in USD and the state sales tax rate as a decimal (e.g., 0.06 for 6%). Both values must be positive numbers.
