The reality is pretty simple: Iowa is a low-tax state for business, and has been for some time. Late last year, the Council on State Taxation released its latest report on how much businesses pay in state and local taxes, prepared by the accounting firm Ernst and Young. Iowa was 18th lowest — only 17 states had a lower overall tax rate on business. (See graph.) Another accounting firm, Anderson Economic Group, ranks Iowa’s business taxes even lower, at 14th — only 13 states have lower taxes.
But why use real data when you can just cite some anti-tax, anti-government think tank that has cobbled together a “competitiveness index” that makes Iowa look bad?
So it is again in 2020. The governor cited the need to be competitive in her condition of the state address, and the Senate president repeated the theme. To support the claim, Senator Charles Schneider pointed to a bogus study by the Tax Foundation that ranked Iowa 42nd among the states in “business tax climate.” Only eight states were worse.
The Tax Foundation, it turns out, mashes together 124 components of state tax systems to produce an overall “index number” to rank the states. Their index is meaningless; it gives weight to components that cannot plausibly affect tax competitiveness, while ignoring features that have a large impact on business taxes.
The last problem is particularly salient for Iowa. Iowa offers single-factor apportionment, which can drastically reduce a corporation’s Iowa tax if they export much of their production. And Iowa is one of the few states that allow corporations to deduct part of their federal income taxes on their state return. Both of these factors are completely ignored by the Tax Foundation. Instead, they focus on things like the number of tax brackets. Meanwhile, the sales taxation of food is a good thing, in their book; Iowa’s failure to tax food somehow makes us less competitive. This is nonsense.
Iowa is a slow growing state, but more tax cuts for those at the top will not help. They will further erode the state’s ability to invest in our roads and bridges, in our children and our workforce, the building blocks of a strong economy. Education, from early childhood through college, not only produces the skilled workforce businesses need, but makes it easier to attract workers from elsewhere, knowing their children will get a good education.
