Sales Tax vs. Use Tax for San Francisco Businesses & Consumers
While sales tax is collected by registered vendors at the point of sale, use tax is a self-assessed tax that applies when taxable goods are purchased from a vendor who did not collect sales tax. The rates for both are identical: 8.625%.
If you purchase equipment, software, or supplies from out-of-state merchants and no tax was charged, you are legally obligated to report and pay use tax to California Department of Tax and Fee Administration (CDTFA). Use tax audits are common — failure to accrue on untaxed invoices is a frequent audit finding.
