Administered locally: county assessors appraise property at 100% of true and fair market value and county treasurers collect; the Department of Revenue oversees but does not collect. It is the top funding source for schools, fire, libraries and parks (about 30% of state/local taxes). Exemptions and deferrals exist for qualifying seniors and people with disabilities.
