FAQ
Frequently asked questions
Do sales tax rates vary by location?
Yes — in the US, rates vary by state, county, and city, and some states have no sales tax at all.
Are all goods taxed at the same rate?
No — many jurisdictions exempt or reduce tax on items like groceries, prescription drugs, or clothing.
Is sales tax the same as VAT?
No — sales tax is charged once at final sale, while VAT is charged at each stage of production; see our VAT Calculator for that model.
