Business Taxes

A highly-competitive tax policy that favors growth

The state of Iowa wants business to succeed. That’s why the state has developed a tax code that favors businesses who locate here with special advantages over other locations.

Single-Factor, Nonunitary Tax

Iowa's corporate income tax is a single-factor, nonunitary tax based only on the percentage of total sales income within the state. For example, an Iowa manufacturer selling all its products outside Iowa pays no Iowa corporate income tax.

Federal Deductibility

Iowa is one of only five states that offers federal deductibility. This allows businesses to deduct 50 percent of federal taxes from any Iowa Corporate Income Tax obligation.
