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

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 2026-05-08.

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

Economic nexus in Idaho triggers at $100,000 in gross sales delivered into Idaho in the current or prior calendar year. No transaction count threshold.
