But, as always, the devil is in the details. It's is an incredibly complex process that, while holding great promise, comes with significant limitations and unknowns.

Sales taxes. The state sales tax rate in Iowa increased to 6% (from 5%) on July 1, 2008. Iowa also collects a corresponding use tax on out-of-state purchases. Local taxing jurisdictions also may impose a local option sales tax if approved by voters. This tax is imposed on the gross receipts from sales of tangible personal property.
The lowest possible total sales tax is 4.5 percent, while the highest possible total rate is 11.5 percent. Sales in the two largest cities, Oklahoma City and Tulsa, are taxed at total rates between 8 and 9 percent. Local governments lose revenue most years due to new exemptions granted by the state legislature.
