This article discusses personal income tax in Iowa
If you are a resident or nonresident of Iowa and receive taxable income individually from property owned or business transacted in Iowa, you are subject to tax on net income. Therefore, if you are operating your business as an S corporation, partnership, limited liability company (LLC), or sole proprietorship, you will be subject to a personal income tax on your business income that passes through to you. In addition, school districts in Iowa are authorized to levy a local income tax, so be sure to check with your local government.
