Why the rate here is not the whole story
Iowa's state rate is 6 percent and local option sales tax is a flat 1 percent that each jurisdiction adopts for itself, so there is no countywide Iowa sales tax rate as such. Cities vote on it one at a time and the county board adopts it separately for the unincorporated area, and a jurisdiction can start or end the tax only on January 1 or July 1. A city whose limits cross a county line is listed once under each county and the two halves can carry different rates, so the department's listing counts it separately in each. All 9 cities the department lists in Sac County have adopted the 1 percent, and so has the unincorporated area, so every address in the county is at 7 percent today. The uniformity is a coincidence of 9 separate local votes rather than a county tax, and any one city rescinding would put that city alone back to 6 percent. The unincorporated area outside the cities has adopted it as well, so the county's own 1 percent applies to every address the department does not list under a city.
How do I find the exact rate for an address in Sac County?
