How Property Tax Works

Washington County, Tennessee operates on a property tax system that funds essential local services including schools, emergency services, infrastructure maintenance, and county operations. For the 2025 tax year, the county's tax rate is $14.50 per $1,000 of assessed value, which represents a decrease from previous years. Property taxes are assessed annually based on the property's value as of January 1st and are due by February 28th of the following year.

Your actual tax rate may vary depending on your location within Washington County due to special taxing districts, municipal boundaries, and school district overlays. These additional assessments can include city taxes, school bonds, fire district fees, and other special purpose levies. The effective tax rate typically ranges from the base county rate to significantly higher amounts when multiple special districts apply to your property location.

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when significant changes occur to a property after the January 1st assessment date. Common triggers include new construction completion, major renovations that add value, ownership transfers that remove exemptions, or corrections to previous assessments. The supplemental tax covers the difference between the original tax assessment and the revised assessment, prorated for the remaining months in the tax year.

For example, if you complete a $100,000 home addition in June that increases your assessed value by $80,000, you would receive a supplemental tax bill for the additional taxes owed from July through the end of the fiscal year. This would be calculated as: $80,000 ÷ $1,000 × $14.50 × (6 months ÷ 12 months) = $580 in supplemental taxes due.

  • Annual Tax: $148,125 ÷ $1,000 × $14.50 = $2,148
  • Monthly Escrow: ~$179

Section 5

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts to ensure timely payment of annual property taxes. Your lender collects 1/12th of your estimated annual property tax with each monthly mortgage payment and maintains these funds in an escrow account. The lender pays your property taxes directly to Washington County when they become due on February 28th.

Lenders typically conduct annual escrow analyses to adjust your monthly payment based on actual tax bills and account balances. If your property taxes increase due to reassessment or new special districts, your monthly escrow payment will increase accordingly. You should receive an annual escrow statement showing all deposits, payments, and any shortage or surplus. Property owners can verify their tax payments and balances through the Washington County Trustee's office or online payment portal.
