Sales Tax

When to Charge Sales Tax

  • WhenÌýthe university sells tangible property to non-university, non-tax-exempt entities, the sale is subject to sales tax. This includes sales made to students, facultyÌýand staff (not acting in an agent capacity on behalf of the university), companies, the general publicÌýand conference catering.
  • There are someÌýCUÌýBoulder campusÌýdepartments that have a large volume of sales (e.g., the Book Store) have their own sales tax license and file/pay their own taxes.
  • Departments with a small volume of sales collect sales tax and let the Campus Controller's OfficeÌýfile and pay the tax.
