The Tax Foundation has posted this interesting entry on which states tax groceries. According to the entry, “states that tax groceries (rate if not fully taxed): Alabama, Arkansas (3%), Hawaii, Idaho, Illinois (1%), Kansas, Mississippi, Missouri (1.225%), Oklahoma, South Dakota, Tennessee (5.5%), Utah (1.75%), Virginia (1.5% + 1% local option tax), and West Virginia (5%).”
However, it is important to note that “Idaho's income tax provides a $20 credit per person that is designed to partially offset the impact of taxing groceries. Also, our source for this data, CCH, cites a Kansas law that allows for a ‘limited tax refund available to disabled, elderly, and low-income households.’”
