Campaigns and Campaign Finance - As enacted, makes various changes to campaign finance laws and related laws. - Amends TCA Title 2; Title 3 and Title 67.

HB 653 updates Tennessee's campaign finance laws by imposing a $150 annual registration fee on political campaign committees (but not candidates), increasing penalties for violations from $100 to $250, and requiring multi-county election candidates to file with all affected county commissions. The bill exempts party-controlled committees from contribution limits while subjecting associated committees to standard limits, and clarifies that campaign funds cannot cover litigation to attack opponents but may fund reputation defense. It also mandates electronic filings under penalty of perjury and extends post-election contribution acceptance periods for officeholders. These changes directly affect campaign committees, candidates, and party organizations managing election finances.
