Washington Revised Code Title 29B. Campaign Disclosure and Contribution § 29B.30.100. Top five contributors to political advertisement (Effective January 1, 2026)

(1) For any requirement to include the top five contributors under RCW 29B.30.050 or any other provision of this title, the sponsor must identify the five persons or entities making the largest contributions to the sponsor in excess of the threshold aggregate value to be considered an independent expenditure in an election for public office under RCW 29B.10.310(1)(d) reportable under this title during the 12-month period preceding the date on which the advertisement is initially to be published or otherwise presented to the public.

(2) If one or more of the top five contributors identified under subsection (1) of this section is a political committee, the top three contributors to each of those political committees during the same period must then be identified, and so on, until the individuals or entities other than political committees with the largest aggregate contributions to each political committee identified under subsection (1) of this section have also been identified. The sponsor must identify the three individuals or entities, not including political committees, who made the largest aggregate contributions to any political committee identified under subsection (1) of this section in excess of the threshold aggregate value to be considered an independent expenditure in an election for public office under RCW 29B.10.310(1)(d) reportable under this title during the same period, and the names of those individuals or entities must be displayed in the advertisement alongside the statement “Top Three Donors to PAC Contributors.”

(3) Contributions to the sponsor or a political committee that are earmarked, tracked, and used for purposes other than the advertisement in question should not be counted in identifying the top five contributors under subsection (1) of this section or the top three contributors under subsection (2) of this section.

(4) The sponsor shall not be liable for a violation of this section that occurs because a contribution to any political committee identified under subsection (1) of this section has not been reported to the commission.

(5) The commission is authorized to adopt rules, as needed, to prevent ways to circumvent the purposes of the required disclosures in this section to inform voters about the individuals and entities sponsoring political advertisements.
