The state sales tax rate in Iowa increased to 6 percent (from 5 percent) 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. It usually remains in effect until it is repealed, but the ordinance may include a sunset clause.
The Department of Revenue has an online sales tax rates lookup tool.
Personal and real property taxes
Property tax is levied on the taxable value of real property -- that is, mostly land, buildings, structures and other improvements that are constructed on or in the land, attached to the land or placed upon a foundation. Typical improvements include buildings, houses or mobile homes, fences and paving.
Five classes of real property are evaluated: residential, agricultural, commercial, industrial and utilities/railroad (which is assessed at the state level).
Residential, commercial and industrial real estate is assessed at 100 percent of market value. Agricultural real estate is assessed at 100 percent of productivity and net earning capacity value.
Iowa has more than 2,000 taxing authorities. Most property is taxed by more than one taxing authority. The tax rate differs in each locality and is a composite of county, city, school district and special levies.
State law requires that all real property be assessed every two years in odd-numbered years. Railroads and public utilities, which are assessed by the Iowa Department of Revenue, are assessed every year.
Iowa offers a variety of full and partial property tax exemptions and credits.
Inheritance and estate taxes
Iowa collects an inheritance tax that ranges from 5 percent to 15 percent, depending on the amount of the inheritance and the relationship of the recipient to the decedent. Form IA 706 must be filed.
The surviving spouse's share, regardless of amount, is not subject to tax. State tax also may be limited or even eliminated for bequests left to other family members. See Form IA 706 for details.
Iowa's estate tax was linked to the federal estate tax. Due to the phaseout of the federal estate tax credit, Iowa no longer imposes an estate tax.
