Sales Tax vs. Use Tax for Columbus 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: 8.000%.
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 Ohio Department of Taxation. Use tax audits are common — failure to accrue on untaxed invoices is a frequent audit finding.
Insurance and financial services and education (OSU) and government companies operating in Columbus should maintain rigorous use tax accrual procedures, especially for equipment and specialized software purchased from out-of-state vendors.
Sales Tax Registration & Permits for Columbus Businesses
Businesses with physical presence or economic nexus in Ohio must register with Ohio Department of Taxation before collecting tax.
Columbus's position as a hub for Ohio State University (OSU / The Ohio State University), State Capitol building, Columbus Zoo and Aquarium means remote sellers shipping to this city should proactively monitor Ohio's nexus thresholds.

Resale Certificates & Tax Record-Keeping in Columbus
Businesses in Columbus must maintain resale certificates and transaction records to comply with Ohio tax audits. If you sell wholesale, obtain a valid resale certificate from the buyer.
