Charitable contributions made to NAU are deductible under Internal Revenue Code section 170.

State law does not exempt from sales tax sales made to NAU, and vendors may pass on to NAU the burden to pay applicable sales and use tax with the exception of certain qualified purchases described in CMP 120, Sales Tax Exemption for Purchases. See CMP 108, Sales Tax, for a listing of sales tax rates.


NAU's IPEDS ID can be used to look up information on the University from the IPEDS College Opportunities On-Line (COOL) web site.
