The Tax Rate For Washington County Tennessee Residents Doesn’t Look As Though It Will Be Changing This Year. The County Budget Committee Has Approved A 126-Million Dollar Proposed 2015-16 Fiscal Year Budget To Be Recommended To The Full Commission. That Plan Does Not Change The Current $1.98 Real Estate Tax Rate. It Does Provide A 2-Percent Cost-Of-Living Raise To All County Employees. It Will Now Go Before The Public At 5pm July 20th And Before The Full Commission The Same Night At 6pm.
