Indiana Use Tax
If, while a resident of Indiana, you made purchases while you were outside Indiana, through the mail (for instance, by catalog or offer through the mail), through radio or television advertising and/or over the Internet, these purchases may be subject to Indiana sales and use tax if sales tax was not paid at the time of purchase. This tax, called “use” tax, is figured at 7 percent.
When you make purchases from a company in Indiana, that company is responsible for collecting the Indiana sales tax from you. When you make purchases from an out-of-state company, you are responsible for making sure the use tax is paid. Either the out-of-state company collects the tax from you or you must pay the tax directly to the State of Indiana.
