ROCKFORD, Ill. (WIFR) – In Winnebago County, voters will see a familiar question on their November ballot concerning a half-cent sales tax for “mental health purposes.”. The referendum first appeared in 2020, when more than 62% approved the effort funding mental health services. A sunset clause requires an extension ratified by a public vote. Before the general election, however, the county board must decide to allow the ballot question.
