How can I get different results using the Basic Tax Calculator in Texas?


You see that the rate at an address changes sometimes when checking with the Basic Tax Calculator (BTC).

  • In Texas the tax rate changes based on the origin and destination address for sales within the state.
    • The rate can change in the BTC if you use a different origin address in TX, even if you do not change the destination address, see Mixed Sourcing
