Campaigns and Campaign Finance - As enacted, revises present law to designate as a political campaign committee for purposes of reporting expenditures pursuant to campaign finance laws a corporation that uses corporate funds, moneys, or credits for communications expressly supporting or opposing the election or defeat of a clearly identified candidate or elected official, and such funds, moneys, or credits are not used with the cooperation or with the prior consent of, or in consultation with, or at the request of, or suggestion of, a candidate or elected official or any agent or authorized committee of the candidate or elected official. - Amends TCA Title 2, Chapter 10.

SB 621 amends Tennessee's campaign finance laws to require corporations that independently spend their own funds on communications expressly supporting or opposing a specific candidate (without the candidate's or their campaign's prior agreement, consent, or consultation) to register as political campaign committees and report their expenditures. This directly affects corporations running ads or communications about elections without coordination with candidates or their official committees. The key provision clarifies that such independent corporate spending must now follow the same reporting rules as traditional campaign committees, increasing transparency in how outside groups influence elections. The law became effective on May 9, 2025, after being signed by the Governor.
