County, city, transit and special-district tax for the address the sale is sourced to. Leave blank to apply the state rate only; the result then shows the combined range the state publishes so you can see what is missing.
Number of items at this price.
Where the state taxes only the difference between the price and a trade-in (Missouri does, under RSMo 144.025), enter the allowance. Leave 0 elsewhere and in reverse mode.

Worked out from Texas Comptroller, Sales and Use Tax: 6.25% state rate; local jurisdictions up to 2% for a maximum combined rate of 8.25% and 6 other sources.
State rates are the general rates each revenue department publishes as of 5 September 2026; local rates change quarterly and depend on the exact address, so confirm the combined rate with the state department for the sale location. Food, lodging, vehicle and other special rates are not modelled.

How this is worked out

3 steps
  1. Custom rate entered: 8.25%
  2. Price before tax = 100 / (1 + 8.25%) = 92.38
  3. Tax included = 100 - 92.38 = 7.62
