Washington County Tennessee Commissioners Are Expected To Decide On A 40 Cent Property Tax Increase Today. If Approved, It Will Be The County’s First Tax Increase Since 2008. The Current Tax Rate Is $1.98 But Would Go To $2.38 Cents If Approved. The Hike Will Be Used To Provide 9 Million For New And Existing Capital Projects. One Big Ticket Item Would Be A New Boones Creek K-8th Grade School As Well As Remodeling Jonesborough’s Existing Elementary And Middle Schools.
