Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in California because of its $500,000 threshold. If you cross that first, you register there first.

On rate: Oregon is friendlier for customers with a combined state + local rate of 0.00% vs 8.99%.

Neither state has a transaction-count trigger — only the dollar threshold matters.

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.

Oregon — nexus note

Oregon has no state or local general sales tax. Sellers do not need to register or collect sales tax on transactions shipped to Oregon customers. Oregon does impose a Corporate Activity Tax (CAT) on certain businesses with Oregon-source revenue over $1M, but this is not a sales tax.

Frequently asked questions

Which state has the lower sales tax nexus threshold, California or Oregon?
Oregon has no statewide general sales tax, so it publishes no economic nexus dollar threshold. California publishes a $500,000 threshold as of 2026-05-21. Local or special taxes can still apply in Oregon; check the official source.
Do both California and Oregon have marketplace facilitator laws?
Not both. California has a marketplace facilitator law; Oregon does not have one recorded in our current data as of 2026-05-21. Confirm against the official state source before relying on facilitator collection.
Which has the lower sales tax rate, California or Oregon?
Oregon has the lower combined state and local sales tax rate at 0.00%, 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 2026-05-21.
Do I need to register for sales tax in both California and Oregon?
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 Oregon's is not applicable (no statewide sales tax). 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 2026-05-21.
When did economic nexus take effect in California and Oregon?
California's economic nexus rule took effect on 2019-04-01, and Oregon's effective date is pending verification. 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.
