Sales tax you collect is not revenue. Move it to a separate account the day you collect it. Rates and rules vary by address and by what you sell. Confirm with your state comptroller or your CPA.
What this assumed
- You supply the rate. This tool does not know your state, county or city rate, and never guesses one.
- It does not handle exemptions, tax holidays or multi-jurisdiction splits.
Runs in your browser. Nothing you type is sent anywhere.
Not tax advice
Tax rules change and vary by state, county and situation. This tool does not know your filing status, deductions or local rates. Confirm anything you plan to file with a tax professional or the current official guidance.
