Frequently Asked Questions

How do taxes work when selling online?

Online sellers typically deal with income tax on profits and, in many cases, sales tax on taxable transactions. Your bookkeeping should track revenue by platform, fees, refunds, shipping, and expenses so quarterly estimates and annual returns are accurate. If you sell across multiple states, you may also need to monitor nexus rules and filing thresholds for sales tax compliance.
