Sales/ Use Tax Exemptions

If you purchase goods/ services for your department, follow the guidelines on this page to avoid costly tax errors.

Evaluate each item for tax applicability

An audit by the California State Board of Equalization found that some department buyers apply tax to items on department orders that are tax-exempt.

Generally, do not apply sales or use tax on:

  • Items delivered outside California and used more than 90 days
  • Transactions with these governments/ agencies:
    • State governments/ agencies in all 50 states, (e.g., state universities)
    • U.S. governments/ agencies
    • Foreign governments/ agencies
  • Materials/ parts for fabrications, where fabricated items are ultimately used outside California (Only apply sales tax.)
  • Items that UCSD buys from a vendor to resell to a consumer; certify this exemption by providing vendors with the University of California Resale Certificate #SXFH-25-610105
  • Occasional sales (less than three sales in a 12-month period)

Specifically, do not apply sales or use tax on:

  • Remote Internet access
  • Advertising
  • Consulting services
  • Exempt subscriptions*
  • Exempt mailing lists*
  • Installation services
  • Optional equipment maintenance agreements
  • Page charges

*Exempt from tax only in certain situations

Note: Computer software is complicated. For more clarification on software and other exemptions, see the UC Sales and Use Tax Manual.

Other types of exemptions

The California State Board of Equalization Sales and Use Tax Regulations define many conditions when UCSD transactions are exempt from sales and use tax. These exemptions depend on the transaction's nature and require a final determination by the purchasing director.
