Blount County, home to Maryville and roughly 137k Tennesseans, uses the simplest residential property tax system of any state we cover: appraised value × 25% assessment ratio × combined tax rate = your bill. Tennessee has no state income tax and no statewide homestead exemption — county and city rates are the entire story. This guide explains how each piece works and what limited tax relief programs exist for elderly, disabled, and veteran homeowners.
How the bill is built
Tennessee's residential property tax calculation has only three steps. Start with your home's appraised value, set by the county property assessor. Multiply by the 25% residential assessment ratio (fixed by the Tennessee Constitution, Article 2, §28) to get your assessed value. Multiply that by the combined county + city tax rate (expressed per $100 of assessed value) to get your tax bill.
For example: a $300,000 home × 25% = $75,000 assessed value. If your combined county + city rate is $3.00 per $100 AV, your bill is $75,000 × (3.00 / 100) = $2,250. That's it — no homestead exemption to subtract, no equalization factor, no circuit breaker.

Tax relief programs in Tennessee
Unlike most other states, Tennessee has no statewide homestead exemption that reduces a primary residence's tax bill. Instead, the state operates targeted relief programs funded by the state and administered by your county trustee. These are income-limited and require annual application.
Elderly/Disabled Tax Relief — up to $167 credit for qualifying homeowners
Tennessee homeowners who are 65+ or totally and permanently disabled, and whose total household income is under $35,690 (2025 limit), may receive state reimbursement of the property tax on the first $30,900 of their home's market value. Typical credit is around $100–$200 depending on the local tax rate. Apply through your county trustee between when tax notices are mailed and the delinquency date.
Disabled Veteran Tax Relief — up to full exemption
Veterans with a 100% service-connected, total and permanent disability receive state reimbursement of property tax on up to $175,000 of market value. For homes valued below this threshold, it's effectively a full exemption. The surviving unmarried spouse of a qualifying veteran is also eligible.
Property Tax Freeze — available in some counties only
Tennessee's local-option Property Tax Freeze locks the tax amount (not the assessed value) for homeowners 65+ with income under a county-set limit. Not all counties have adopted the freeze. Contact your county trustee to confirm whether Blount County offers it.
Greenbelt Assessment — for farm and forest land
Not technically a homestead program, but significant: agricultural, forest, and open-space land can be assessed at its use value rather than market value, dramatically reducing the tax base for working farms and timberland. Apply with the Blount County Assessor of Property.
Appealing your assessment
Tennessee reappraises property on a 4, 5, or 6-year cycle set by each county (Blount County's cycle varies). If you disagree with your appraised value, first request an informal review with the Blount County Assessor of Property. If unresolved, appeal to the County Board of Equalization (which meets each June), then to the Tennessee State Board of Equalization, and finally to the Tennessee chancery court.
