Which state is easier for sellers?

For low-revenue sellers: nexus triggers first in both states because of its threshold. If you cross that first, you register there first.

On rate: Alaska is friendlier for customers with a combined state + local rate of 1.83% vs 9.51%.

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

Washington — nexus note

Washington sales tax nexus and economic nexus threshold: $100,000 in gross receipts sourced or attributed to Washington in the current or prior year (eff. 2020-01-01). The transaction-count threshold was eliminated when this unified threshold took effect. Crossing the threshold registers a remote seller for both retail sales tax AND Business & Occupation (B&O) tax — Washington classifies remote-seller revenue under the Retailing B&O classification, and a "No Local Activity" deduction is available when the seller has no in-state physical B&O nexus. Marketplace facilitator law (RCW 82.08.0531; marketplace facilitator defined at RCW 82.08.010(15)) applies the same $100,000 Washington-receipts threshold to marketplaces — Amazon, Etsy, eBay, and Walmart collect and remit Washington sales tax on third-party transactions they facilitate, and have provided monthly Washington-sales reports to their sellers since 2019-07-01. Direct-to-consumer Washington sales you make outside any marketplace continue to count toward your own $100,000 economic-nexus calculation.

Alaska — nexus note

Alaska has no state-level sales tax, but many municipalities impose local sales tax. Remote sellers with $100,000 or more in statewide gross sales must register with the Alaska Remote Sellers Commission (ARSLC) and collect applicable local rates.

Frequently asked questions

Which state has the lower sales tax nexus threshold, Washington or Alaska?
Both Washington and Alaska publish the same economic nexus dollar threshold of $100,000, so a remote seller would reach each state's published threshold at the same level of in-state sales. These are the thresholds published by each state's tax authority as of 2026-05-26; confirm against the official source before registering.
Do both Washington and Alaska have marketplace facilitator laws?
Yes. Both Washington and Alaska 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. Direct-to-consumer sales you make outside a marketplace remain your own responsibility once you cross each state's threshold. Verified 2026-05-26.
Which has the lower sales tax rate, Washington or Alaska?
Alaska has the lower combined state and local sales tax rate at 1.83%, compared with 9.51% in Washington. These are the statewide base rate plus the average local rate; the exact rate depends on the customer's delivery address. As of 2026-05-26.
Do I need to register for sales tax in both Washington and Alaska?
It depends on where you cross each state's economic nexus threshold (or have physical presence there). Washington's published threshold is $100,000, and Alaska's is $100,000. 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 2026-05-26.
When did economic nexus take effect in Washington and Alaska?
Washington's economic nexus rule took effect on 2020-01-01, and Alaska'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.
