New report exhibits flat revenue taxes also can redistribute tax burden


A brand new evaluation discovered that reaching a “honest” state revenue tax system is extra difficult than the controversy between a flat tax price and a graduated price would recommend.

The Coverage Highlight, titled The Earth isn’t Flat, and Neither is Illinois’— or some other state’s— Earnings Tax, discusses the various components that decide state private revenue tax liabilities and demonstrates that graduated tax charges usually are not the one technique to obtain a progressive tax system.

The report is co-published by the College of Illinois Chicago’s Authorities Finance Analysis Middle and the College of Illinois System’s Institute of Authorities and Public Affairs. A analysis temporary, summarizing key takeaways of the report, will be discovered on-line. 

“Oversimplifying tax-policy selections can result in symbolic victories that do little to advertise equity,” stated David Merriman, a co-author of the Coverage Highlight and the James J. Stukel Presidential Professor of Public Administration within the School of City Planning and Public Affairs at UIC. “Switching from a flat to a graduated tax-rate system won’t mechanically promote progressivity, and our analysis exhibits that even a flat tax system can permit tax burdens to rise with revenue.” 

The authors appeared to Illinois as an example this level. In 2011, Illinois had one statutory state revenue tax price of 5%. Nevertheless, the share of revenue that tax filers truly paid various from beneath zero to greater than 5%. The report discovered that the precise tax burden:

  • Was between 4.5% and 5% for under about 4% of tax filers and was higher than the statutory price of 5% for about 4.3% of filers.
  • Was zero for a small portion of the center third of tax filers, was between 4% and 5% for about 60% of them and was above 5% for about 3.9% of filers on this group.
  • Was comparable for tax filers within the center and high thirds of revenue distribution, however barely extra tax filers within the high third had a mean price close to or above 5%.

The report comes as Illinois and different states contemplate totally different plans for increasing their Earned Earnings Tax Credit, which complement the earnings of low-wage staff. The authors notice that the EITC is a vital driver within the variance between charges. One other issue that may make the charges tax filers pay differ from the statutory price is that states usually cap the worth of tax exemptions and tax credit. Tax filers could face abrupt shifts in charges when their incomes rise they usually hit the cap on a credit score or an exemption.

“Equity in state revenue tax methods requires loads of consideration to element,” stated Merriman, who co-leads IGPA’s Fiscal and Financial Working Group and serves as interim dean of the School of City Planning and Public Affairs. “We need to ensure that particular person taxpayers usually are not harm due to comparatively arbitrary guidelines like most limits on tax credit or exemption quantities. Our analysis exhibits that, even when tax filers observe the letter of the regulation, very comparable taxpayers can typically have fairly totally different tax liabilities.”
