Under RCW 23.95.520, all 13 items. MOST IMPORTANT: item (1)(m), "Employing a remote worker who resides in Washington state," was added by 2026 c 80 s 7 and is an express statutory safe harbor for remote employment. It is unqualified on its face, with no headcount cap and no role exclusion. Washington appears to be the first state to enact one. The amendment is current on the legislature's site but has not propagated to most secondary publishers, so many other sources still show the pre-2026 12-item list. Subsection (4) confirms the carve-out is registration-only and does not shelter the company from B&O tax, payroll tax, or service of process.
