Information technology products and services

This quick reference guide is intended to provide guidance regarding the taxability of information technology (IT) products and services 

Non-itemized charges: Generally, when IT products and services are sold as a non-itemized package, the entire transaction is subject to retail sales or use tax. For example, if prewritten computer software, customization of prewritten computer software, and installation services are sold for one non-itemized price, the entire charge is subject to retail sales tax or use tax.

Itemized charges: When the products and services are separately stated on a sales invoice or contract, charges for computer hardware and prewritten computer software are subject to retail sales or use tax. Separately stated charges for custom software and customization of prewritten software are not subject to retail sales or use tax.
