Revise campaign finance laws to limit certain tax-exempt organization contributions

SB 529 would limit contributions from certain tax-exempt nonprofits (like 501(c)(4) groups) to Montana political committees. It sets a $2,500 cap on such contributions to support or oppose candidates or ballot measures, bans direct contributions to candidates, and prohibits contributions if the nonprofit received foreign donations in the past four years. The bill directly affects tax-exempt organizations and political committees, aiming to increase transparency in campaign financing. It does not apply to regular voters or general public funding. (Note: The bill died in committee in May 2025 and did not become law.)
