How Property Tax Works

Hamilton County, Tennessee operates on a property tax system that funds essential local services including schools, public safety, infrastructure, and county government operations. For the 2025 tax year, Hamilton County achieved a historic milestone with a certified property tax rate of $1.51 per $100 of assessed value—the lowest rate in over 80 years since 1941. This rate applies to the assessed value of real and personal property within the county boundaries.

Property tax rates in Hamilton County vary by location due to special taxing districts, municipal boundaries, and additional assessments for services like fire protection, libraries, or utility districts. Property owners may pay different effective rates depending on whether they reside within city limits, rural areas, or special service districts. The county completed a four-year countywide reappraisal process, which contributed to the ability to lower the overall tax rate while maintaining essential services.

Section 4

Supplemental Tax Bills

Supplemental taxes in Hamilton County are triggered by changes in property ownership, new construction, or significant improvements that increase assessed value during the tax year. When these events occur, the county issues additional tax bills to capture the increased value for the remainder of the fiscal year. The supplemental tax is calculated by determining the difference between the old and new assessed values, multiplying by the applicable tax rate, and prorating for the remaining months in the tax year.

For example, if you purchase a home in September that was previously under-assessed, or complete a major renovation, you may receive a supplemental tax bill. The bill covers the period from when the change occurred through February 28 of the current tax year. These supplemental assessments ensure that property taxes reflect current ownership and property values throughout the fiscal year.

Escrow & Property Taxes

Most mortgage lenders in Hamilton County require borrowers to establish an escrow account for property tax payments. Your lender collects monthly payments equal to 1/12 of your annual tax bill plus insurance premiums. The lender pays your property taxes directly to Hamilton County before the February 28 deadline to avoid penalties and protect their security interest in the property.

Lenders typically review escrow accounts annually and may adjust monthly payments based on actual tax bills received. Since Hamilton County mails tax bills in October and taxes are due by February 28, lenders usually make payments in January or February. Property owners should verify that their lender has the correct tax amount and payment schedule, especially following the recent rate reduction and reappraisal cycle. You can monitor payment status through the Hamilton County Trustee's office or online payment portal.
