Sales Tax FAQs
What's the difference between sales tax and VAT/GST?
Sales tax is applied only at the final sale to consumers, while VAT/GST is applied at each stage of production. Businesses can claim back VAT/GST paid on inputs.
How do I calculate sales tax backwards from total?
Use the reverse calculation method: Original Price = Total Price ÷ (1 + Tax Rate). For example, $107.25 total with 7.25% tax = $107.25 ÷ 1.0725 = $100.
Are online purchases subject to sales tax?
Yes, most online purchases are subject to sales tax based on the buyer's location. Rules vary by jurisdiction and business size thresholds.
What items are typically tax-exempt?
Common exemptions include groceries, prescription drugs, clothing (in some states), educational materials, and purchases by non-profit organizations.
How often do tax rates change?
Tax rates can change annually or even more frequently. Always check current rates with local tax authorities for accurate calculations.
