Requires assent of two-thirds of the members for any bill that enacts or increases tax revenues

S 1308 requires a two-thirds vote in both the state legislature and local governing bodies to pass bills that create new taxes, increase existing taxes, or extend tax collection periods. This applies to all tax-related bills except those resulting from home rule requests under state constitution provisions. The bill directly affects state legislators and local government officials (like city councils or county boards) who must secure supermajority approval for tax changes. It does not alter current tax rates but changes the legislative process needed to enact or raise them. The law takes effect immediately upon passage.
