Yes. Our database combines state, county, and special district taxes to calculate the full “combined rate” you’ll actually pay at checkout.
How often are sales tax rates updated?
Sales tax rates are updated as soon as official changes are released by state Departments of Revenue. Major updates occur quarterly, and minor adjustments can happen monthly.
Do I need to create an account to use QuickTaxCalc?
No account or signup is required. All calculators are free to use — just enter your amount or ZIP code to get instant results.
What is the average sales tax rate in the U.S.?
The national average combined sales tax rate is around 7%. This includes both the average state rate (about 5.2%) and average local add-ons (about 1.8%).
Are groceries and prescription drugs taxable?
In most states, basic groceries and prescription medications are exempt from sales tax. However, some states apply reduced rates or tax prepared food separately.
