Why the rate here is not the whole story
Grayson County levies no sales tax of its own. Everything above the 6.25 percent state rate comes from cities, transit authorities and special purpose districts, and none of those follow the county line, so there is no single countywide rate to quote. The low end of 6.25 percent is what applies where no city and no partial special purpose district reaches; the high end of 8.25 percent is the most the Comptroller lists anywhere in the county. Texas caps the combined local share at 2 percent, so no address here exceeds 8.25 percent.
How do I find the exact rate for an address in Grayson County?
Use Texas's own address lookup. In Grayson County the rate depends on the address, anywhere from 6.25% to 8.25%.
Who has to collect sales tax in Grayson County?
