Understanding sales tax in Texas.
Texas state sales tax is 6.25%. However, when transacting within Texas, the total sales tax rate paid is often higher due to local county, city, or special district surtaxes.
How to Back Out Sales Tax in Texas
To separate the sales tax from the total paid gross amount for a transaction in Texas, use the standard reverse tax formula:
Base Price = Gross Amount / (1 + (Combined Tax Rate / 100))
For instance, if your combined tax rate (including Texas state rate of 6.25% and a local rate of 1.50%) is 7.75%, the formula becomes:
Base Price = Gross Amount / 1.0775
After deriving the base price, calculate the sales tax portion by subtracting it from the total gross amount.
