How Property Tax Works

Wilson County, Tennessee operates on a property tax system that funds essential local services including public schools, county government operations, emergency services, and infrastructure maintenance. Property taxes are calculated based on the assessed value of real estate, which is determined at 25% of the property's appraised market value. The effective tax rate for levy year 2025 is approximately 2.50% of assessed value, though this can vary significantly depending on your location within the county.

Actual tax rates vary by location due to special taxing districts within Wilson County. Properties may be subject to additional assessments for school bonds, fire districts, utility districts, or other special services depending on their geographic location. The county reassesses all property periodically to ensure fair market valuations, and property owners receive tax notices in mid-October each year. Understanding your specific tax obligations requires knowing not only the base county rate but also any special district assessments that apply to your property's location.

Supplemental Tax Bills

Supplemental taxes in Wilson County are additional property tax bills issued when there are changes to property ownership, value, or use during the tax year. The most common triggers include new construction completion, property transfers that remove exemptions or credits, additions or improvements that increase assessed value, and changes in property use classification. These supplemental assessments ensure that tax obligations are properly allocated for the portion of the year when changes take effect.

Supplemental taxes are calculated by determining the difference between the old and new assessed values, applying the current tax rate to that difference, and prorating the amount based on the number of months remaining in the tax year. For example, if a $50,000 home addition is completed in July, increasing your assessed value by $12,500 (25% of $50,000), you would owe supplemental taxes on that $12,500 for the remaining six months of the tax year. At a 2.50% rate, this would result in approximately $156 in supplemental taxes ($12,500 × 0.025 × 0.5 years).

Example 3: $1,000,000 Property

Escrow & Property Taxes

Most mortgage lenders in Wilson County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, depositing these funds into an escrow account. When taxes become due, the lender pays the county directly from your escrow account. This system protects both you and the lender by ensuring taxes are paid on time and preventing potential tax liens on the property.

Escrow accounts are typically analyzed annually to ensure adequate funding. If your property taxes increase due to reassessment or rate changes, your lender may require higher monthly escrow payments or request a lump sum to cover any shortage. You should receive an annual escrow statement showing all deposits and payments. If you pay taxes independently without escrow, remember that Wilson County issues tax notices in mid-October with the first installment due January 31st. Verify with your lender whether they're handling tax payments or if you need to pay directly to avoid late penalties.
