Frequently asked questions

How do I find my sales tax rate?
Combined state and local rates vary by city and county. Your receipt usually lists it, or your state revenue site has a lookup by address.
How does removing tax work?
Given a tax-included total, the calculator divides out the rate to recover the original pre-tax price and the tax portion — handy for expense reports.
Is my data sent anywhere?
No. Every calculation runs in your browser. Nothing you type is uploaded, logged or stored, and the numbers reset when you close the tab.
