The first report by a self-proclaimed conservative think tank in Iowa is getting some attention today, and reviving dubious ideas about taxes.
First, we applaud the recognition from Engage Iowa that our state’s various tax rates are not as high as they appear at first blush, because of federal deductibility — which permits tax filers to reduce their state taxable income for federal taxes paid. Ending federal deductibility, which Engage Iowa proposes, is something Iowa should consider. That would allow lowering the top rate to around 7 percent and eliminate the perception problem the group is so concerned about.
Unfortunately, however, this is not a well-thought-out plan to improve fairness and simplicity in Iowa taxes, or to assure adequate revenues for schools and other critical services, which are the best way to promote economic growth.
It compounds the overall regressive nature of Iowa taxes — and does nothing to help low- to moderate-income working families. In fact, for many families it would destroy the most important recent advance — the Earned Income Tax Credit. Some 147,000 recipients making over $10,000 — 70 percent of all EITC recipients — would lose the EITC.
While raising low-income Iowans’ taxes, the plan would buy down income-tax rates for higher-income Iowans with a sales tax increase. This would compound existing inequities in Iowa’s state and local tax system, which taxes the bottom 80 percent of taxpayers at about 10 percent, and the highest earners only 6 percent. The big winners would be those with the highest incomes.
The report’s claims about taxes and migration fly in the face of much published academic research showing that in fact taxes have very little influence on interstate migration. The claims that the flat tax would result in substantial economic gains to the state are highly suspect.
Finally, the group’s argument rests on discredited assumptions about Iowa’s so-called “business climate” and ignores the fact that Iowa already is very — perhaps overly — friendly to business. The plan places a great deal of weight on the Tax Foundation rankings, which have been thoroughly debunked. The author could have consulted more credible rankings of business climate, such as the Anderson Economic Group (which places Iowa 20th best, with below-average business taxes) or Ernst and Young, which has Iowa 28th, with an effective rate equal to the national average.
In short, the plan focuses mostly on a perception about Iowa taxes, a perception that is inaccurate but is cultivated by anti-tax forces, rather than ways to improve the stability and sustainability of funding for the critical public services on which all Iowans depend.
