California — nexus note
California sales tax nexus and economic nexus threshold: CDTFA guidance says remote retailers must register and collect California use tax when total combined sales of tangible personal property for delivery into California exceed $500,000 during the preceding or current calendar year. California uses a sales-only threshold — no transaction-count test. AB 147 replaced the earlier $100,000/200-transaction Wayfair threshold with the current $500,000 standard, and related-person sales count toward the threshold. CDTFA marketplace guidance says sellers include both direct California sales and marketplace-facilitated sales when testing the $500,000 threshold, but sellers whose California sales are entirely facilitated by registered marketplace facilitators may not need separate registration for those marketplace transactions. Direct-to-consumer sales outside a marketplace remain the seller's own collection responsibility once California nexus is met.
Ohio — nexus note
Ohio sales tax nexus and economic nexus threshold: effective August 1, 2019, out-of-state sellers have substantial nexus when Ohio gross receipts exceed $100,000 or the seller has at least 200 Ohio transactions in the current or previous calendar year. Ohio marketplace-facilitator rules use the same $100,000-or-200-transaction test, counting the facilitator's own Ohio sales plus sales facilitated for marketplace sellers. Marketplace sellers with Ohio sales through facilitators plus direct channels may need a seller's use tax account once combined Ohio sales exceed the threshold, but collect only on taxable direct sales that are not collected by a facilitator.

Frequently asked questions
- Which state has the lower sales tax nexus threshold, California or Ohio?
- Ohio has the lower economic nexus threshold at $100,000, versus $500,000 in California. A seller's Ohio sales would reach the published Ohio threshold first. These are the thresholds published by each state's tax authority as of 2026-06-03; confirm against the official source before registering.
- Do both California and Ohio have marketplace facilitator laws?
- Yes. Both California and Ohio have marketplace facilitator laws, so marketplaces such as Amazon, Etsy, and eBay collect and remit sales tax on the sales they facilitate in both states.

- Which has the lower sales tax rate, California or Ohio?
- Ohio has the lower combined state and local sales tax rate at 7.29%, compared with 8.99% in California. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-06-03.
- Do I need to register for sales tax in both California and Ohio?
- It depends on where you cross each state's economic nexus threshold (or have physical presence there). California's published threshold is $500,000, and Ohio's is $100,000 or 200 transactions. You generally register in a state only once you cross its threshold, so you may have an obligation in one, both, or neither. Run the nexus calculator with your actual sales and confirm with each state's official source. Thresholds as of 2026-06-03.
- When did economic nexus take effect in California and Ohio?
- California's economic nexus rule took effect on 2019-04-01, and Ohio's took effect on 2019-08-01. Both stem from the 2018 South Dakota v. Wayfair Supreme Court decision, which let states require remote sellers to collect once an economic threshold is met.
