FAQ
How is sales tax calculated?
Sales tax is calculated by multiplying the pre-tax purchase price by the sales tax rate. For example, an item costing $100 with an 8% sales tax rate would have $8.00 in sales tax for a total of $108.00.
What is the average sales tax rate in the US?
The average combined state and local sales tax rate in the US is approximately 6-7%, but it varies significantly. Rates range from 0% in states like Oregon and Montana to over 10% in some jurisdictions when combining state and local taxes.
Are all items subject to sales tax?
No. Many states exempt groceries, prescription medications, and clothing from sales tax. The specific exemptions vary by state and locality. Check your local tax authority for details.
