State preset + local rate, discount, shipping
Preset fills this automatically.
Shipping tax rules vary by state/item. Toggle as needed.
This free US sales tax calculator helps you estimate sales tax using a state preset plus your local rate. Add discount and shipping, choose whether shipping is taxable, and calculate totals instantly. Use “After tax” mode if you only know the final price and want to reverse-calculate subtotal and tax.
Why local tax input? US sales tax changes by city/county, so local input gives a more accurate total.
Are presets exact? Presets cover state-level rate only; local varies by location.
Is this free? Yes.
