Fifteen states have back-to-school sales tax holidays in late July through August this year, with items ranging from computers to backpacks to clothing exempt from state sales tax. Exemptions vary by state, but generally, items of clothing that cost less than $100 qualify. Among states that offer an exemption on computers, the upper limit ranges from $750 to $1,500. Diane Yetter, founder of the Sales Tax Institute, suggests paying attention to retailers’ ads because some retailers will have bigger and better sales leading up to or right after the tax holiday. We've compiled a state-by-state look at sales tax breaks. See if your state offers savings.
