Economic Nexus in Hawaii
Following the 2018 South Dakota v. Wayfair Supreme Court decision, Hawaii can require out-of-state sellers to collect sales tax if they meet certain thresholds. The most common thresholds are $100,000 in sales or 200 transactions per year in the state, though Hawaii's specific rules may vary.
