Which state has the lower sales tax nexus threshold, Idaho or Oregon?

Oregon has no statewide general sales tax, so it publishes no economic nexus dollar threshold. Idaho publishes a $100,000 threshold as of 2026-06-24. Local or special taxes can still apply in Oregon; check the official source.

Do both Idaho and Oregon have marketplace facilitator laws?

Not both. Idaho has a marketplace facilitator law; Oregon does not have one recorded in our current data as of 2026-06-24. Confirm against the official state source before relying on facilitator collection.

Which has the lower sales tax rate, Idaho or Oregon?

Oregon has the lower combined state and local sales tax rate at 0.00%, compared with 6.03% in Idaho. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-06-24.

Do I need to register for sales tax in both Idaho and Oregon?

It depends on where you cross each state's economic nexus threshold (or have physical presence there). Idaho's published threshold is $100,000, 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 2026-06-24.

When did economic nexus take effect in Idaho and Oregon?

Idaho's economic nexus rule took effect on 2019-06-01, 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.

Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in Idaho because of its $100,000 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 6.03%.

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

Idaho — nexus note

Idaho sales/use tax nexus and economic nexus threshold: effective June 1, 2019, an out-of-state retailer without a physical presence in Idaho must collect Idaho sales tax once its combined Idaho sales exceed $100,000 in the current or previous calendar year. Idaho uses a sales-only threshold — no transaction-count test. The threshold counts all Idaho retail sales — taxable, exempt, wholesale, and sales facilitated through third-party marketplaces — and marketplace-facilitated sales still count toward a seller's own threshold even when the marketplace collects the tax. A marketplace facilitator without Idaho physical presence must register and collect once the combined total of its own sales plus the sales it facilitates for retailers exceeds $100,000. Idaho's state sales tax rate is 6%, with limited local resort-city and auditorium-district taxes. Idaho State Tax Commission source data last retrieved 2026-06-14.

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.
