Pinellas County isexpected to keep the county's tax rate the same when it approves next year's budget tonight. The public is invited to speak during the second and final public hearing on the budget, which takes effect Oct. 1. Commissioners gave preliminary approval to the budget of $1.557-billion on Sept. 7. The proposed budget is $13-million less than the current spending plan. If approved, residents would pay the same countywide property tax rate of about $6.80 per $1,000 of taxable property value. Unincorporated residents pay an additional tax for municipal services and that tax will not increase from its current rate of about $2.36 per $1,000. Cities charge their residents an additional tax for services. All county residents pay other taxes, such as one for schools. The public hearing will be held at 6:30 p.m. in the Board of County Commissioners' fifth floor conference room, at the Pinellas County Courthouse, 315 Court St., in Clearwater.
