Frequently Asked Questions – Sales Tax Calculator
To calculate sales tax: multiply the item price by the tax rate percentage. For example, a $100 item with 8.25% tax = $100 × 0.0825 = $8.25 tax. The total price would be $108.25. Our calculator handles this automatically and includes options for discounts, shipping, and multiple items.
The calculator includes current state-level base sales tax rates for all US states. However, local taxes (city, county, district) may apply in addition to state rates. Total tax rates can vary significantly within states. Always verify current rates with local tax authorities for official purposes.
To find the original price from a tax-inclusive total: divide the total by (1 + tax rate). For example, if the total is $108.25 with 8.25% tax: $108.25 ÷ 1.0825 = $100 original price. Use our “Remove Tax from Total” option for automatic calculation.
Shipping tax rules vary by state. Some states tax shipping charges, others don’t. Generally, if shipping is separately stated and reasonable, it may not be taxed. However, if shipping seems excessive or is bundled with the product price, it might be taxable. Check your state’s specific rules or use our calculator’s shipping tax option.
Common sales tax exemptions include: groceries (in many states), prescription medications, medical devices, clothing (in some states), textbooks, and items purchased for resale with valid resale certificates. Non-profit organizations may also qualify for exemptions. Exemption rules vary significantly by state and item type.
