SB 310

Authorizes a county with a pre-existing surcharge to continue the surcharge after December 31, 2030, at a lower rate of one-fourth per cent. Authorizes counties that have not adopted a surcharge ordinance on state tax to adopt a surcharge ordinance at the current rate of one-half of one per cent through December 31, 2030, and at a rate of one-fourth of one per cent after December 31, 2030. Expands the authorized use of surcharge revenues to more than capital costs of a locally preferred alternative for a mass transit project for counties with a population greater than five hundred thousand.
