How to calculate Georgia sales tax
Multiply the price by the combined rate. At the 4% state rate, a $250.00 sale carries $10.00 of sales tax, for a total of $260.00. Add the county, city or district rate for the delivery address to get the full rate for that sale.
To find the tax inside a total that already includes it, divide the total by 1 plus the rate. A $107.00 receipt at 4% is $102.88 before tax and $4.12 of tax.
