The purpose of the CAT tax, which went into effect on July 1, 2005, was to replace the corporate franchise tax and the tangible personal property tax with one, less burdensome tax. The elimination of the tangible personal property tax was intended to benefit manufacturers, who no longer have to pay tax on inventory and equipment. However, the CAT tax has a negative impact on businesses with slim profit margins and high volumes, such as grocery stores. The CAT tax is based on revenue, not profits. The Ohio Grocers Association sued, saying the CAT tax violates the Ohio Constitution's prohibition against taxing food that will be consumed off-premises. See Ohio Gocers Association v. Ohio Tax Commissioner, Franklin County Common Pleas Court Case No. 06 cv 002278 on the Franklin County Docket. The Tax Foundation also feels the CAT tax is unconstitutional because of the way it taxes out of state businesses.
