1. What is the IRS Sales Tax Deduction?

The IRS allows taxpayers to deduct either state and local income taxes or state and local sales taxes, but not both. The sales tax deduction can be calculated using actual receipts or the IRS's optional sales tax tables.

2. How Does the Calculator Work?

The calculator uses the basic sales tax formula:

Where:

• \( Sales \) — Total taxable sales amount in USD
• \( Rate \) — Sales tax rate as a decimal (e.g., 0.08 for 8%)

Explanation: This simple multiplication gives the deductible amount for sales tax purposes.

3. Importance of Sales Tax Calculation

Details: Accurate sales tax calculation is crucial for proper tax filing, especially for those who choose to deduct sales tax instead of state income tax.

4. Using the Calculator

Tips: Enter total sales amount in USD and the applicable sales tax rate as a decimal (e.g., 0.075 for 7.5%). Both values must be positive numbers.
