What Is Property Tax in Tennessee and How Is It Calculated?

Property tax in Tennessee is a local tax on real estate and certain business property, calculated by multiplying your property’s appraised value by a state-set assessment ratio and then by a local rate expressed per $100 of assessed value. The statewide effective rate averages roughly 0.78%, which puts Tennessee in the lower half of all states. Because Tennessee has no state income tax, these local property taxes do most of the heavy lifting for county and city budgets, funding schools, roads, and emergency services.¹

How Your Tax Bill Is Calculated

Three numbers determine what you owe: the appraised value of your property, an assessment ratio set by state law, and a tax rate set by your county or city. The formula is straightforward once you see the pieces.

Appraised value is what your county assessor determines the property would sell for between a willing buyer and a willing seller. State law requires appraisals to reflect the property’s “sound, intrinsic and immediate value” using manuals approved by the State Board of Equalization.²

Assessment ratio converts that appraised value into a smaller “assessed value” that you actually pay tax on. For residential property, the ratio is 25%, so a home appraised at $300,000 has an assessed value of $75,000.³

Tax rate is set each year by your county commission and, if you live inside city limits, by your city council as well. Rates are expressed per $100 of assessed value. A rate of $2.50 means you pay $2.50 for every $100 of assessed value.⁴

Put together: (appraised value × assessment ratio) ÷ 100 × tax rate = your bill. Take a $400,000 house with the 25% residential ratio and a county rate of $2.50. The assessed value is $100,000. Divide by 100 to get 1,000, multiply by $2.50, and the county tax is $2,500.⁴ A city tax, if you owe one, is calculated the same way with the city’s rate and added on top.

Assessment Ratios by Property Type

The ratios are fixed in state law, so they are the same in every county:³

Residential property: 25% of appraised value
Farm property: 25% of appraised value
Commercial and industrial property: 40% of appraised value
Business tangible personal property: 30% of depreciated value⁵
Public utility property: 55% of appraised value

The split matters most to commercial owners, who pay on nearly double the share of value that homeowners do.

Reappraisal Cycles and the Certified Tax Rate

Tennessee counties do not reappraise every year. State law requires a full reappraisal of all real property on a cycle of four to six years, with the specific interval chosen by the assessor and approved by the county governing body. The State Board of Equalization can approve a shorter four-year cycle or extend a cycle in limited circumstances.⁶ Between reappraisals, your appraised value generally stays flat unless you build an addition or make significant improvements.

Values usually jump at reappraisal. To stop that jump from quietly becoming a tax hike, Tennessee’s truth-in-taxation law requires each county and city to calculate a certified tax rate, which is the rate that would raise roughly the same total revenue as the prior year after adjusting only for new construction. If the local government wants to set a rate above the certified rate, it has to hold a public hearing and take a formal vote to exceed it.⁷ Reappraisal years are the ones to pay attention to local budget hearings.

When Taxes Are Due and What Late Costs

Property taxes for the current year become due on the first Monday in October.⁶ You have until the end of February to pay without penalty. On March 1, the taxes become delinquent and interest of 1.5% per month starts accruing on the unpaid balance.⁸ That works out to 18% a year.

Payments go to the county trustee’s office. If you also owe city taxes, you may pay through the trustee or through the city recorder depending on the municipality. Most counties take payment online, in person, or by mailed check.

Unpaid taxes don’t stay a billing problem forever. When they remain delinquent long enough, the county can sue, obtain a court order, and sell the property at public auction to satisfy the tax lien. The property is advertised beforehand, and the taxpayer can stop the process at any point by paying everything owed. Former owners also get a redemption period after the sale to reclaim the property by paying the full amount plus costs. The length depends on how far behind the taxes were when sold:⁹

Five years or less delinquent: one year to redeem
More than five but less than eight years: 180 days
Eight or more years: 90 days

The redemption clock starts when the court confirms the sale, not at the auction. Interest compounds monthly from March 1, so catching up early is always cheaper than catching up later.

Programs That Can Lower Your Bill

Several programs reduce property tax for people who qualify. Each targets a different group, so check the one that fits your situation.

Relief for Elderly and Disabled Homeowners

The state-funded Property Tax Relief Program reimburses a portion of taxes paid by homeowners who are at least 65 years old or who have a total, permanent disability, if household income is below a threshold set each year in the state’s General Appropriations Act.¹⁰ The income ceiling adjusts annually with the Social Security cost-of-living adjustment. For 2026, the maximum appraised value the state will reimburse taxes on is $33,600.

This is a reimbursement, not an exemption. You still get the tax bill, still owe it by the deadline, and still pay it. The state sends a check afterward covering the taxes on the capped portion of your home’s value.¹⁰ You apply through your county trustee with proof of age or disability and income documentation.

Relief for Disabled Veterans

Disabled veterans and their surviving spouses can qualify under broader rules than most assume. You do not necessarily need a 100% rating. Tennessee law covers veterans with a service-connected permanent and total disability rating from the VA, and also veterans with paraplegia, permanent paralysis of both legs, loss or loss of use of two or more limbs, legal blindness, or a 100% disability rating from being a prisoner of war.¹¹ The maximum appraised value eligible for reimbursement is higher under the veterans’ program than under the general elderly and disabled program.

Tax Freeze for Seniors

Separate from the reimbursement program, Tennessee lets counties and cities adopt a property tax freeze for homeowners 65 and older. The freeze locks your bill at the amount you paid the year you first qualified, so later rate increases and reappraisals don’t push it up as long as you stay eligible. The catch is that only jurisdictions that have opted in offer it. As of 2026, around 27 counties and 36 cities participate.¹²

You must be 65 or older, own your principal residence in a participating jurisdiction, and have household income below the limit your county has set for that tax year. The limit varies by county and is recalculated annually. You must reapply every year with updated income documentation.¹²

Greenbelt for Farm, Forest, and Open Space Land

Tennessee’s Agricultural, Forest, and Open Space Land Act of 1976, usually called the Greenbelt Act, lets qualifying land be taxed on its current use rather than its highest potential value. A farm near a growing city gets taxed as farmland, not as future subdivision lots. The savings can be large where development pressure is high.¹³ Minimums vary by classification:

Agricultural land: at least 15 acres actively used for producing or growing agricultural products. There is a rebuttable presumption of qualification if the land averages at least $1,500 in gross agricultural income over any three-year period, though income alone is not the test.¹³
Forest land: at least 15 acres with tree growth managed under a sustained yield program.
Open space land: at least 3 acres in open or natural condition, not in agricultural or forest use.

Pulling land out of Greenbelt or changing its use triggers rollback taxes covering the difference between what you paid under Greenbelt and what you would have paid at full market-value assessment, typically for the prior three to five years. Plan for that bill before selling Greenbelt land for development.

If Your Appraisal Looks Too High

Tennessee gives you a tiered appeal process, and most disputes end at the first or second step.

Start with an informal review at the county assessor’s office. Bring comparable sales or point out errors in the property record. This resolves many straightforward mistakes quickly.
If that doesn’t work, file a formal appeal with the County Board of Equalization. You have to go through this step before escalating.¹⁴
From there, you can appeal to the State Board of Equalization by August 1 of the tax year or within 45 days of the county board’s decision, whichever is later. An administrative judge holds a hearing and issues a decision within 90 days.¹⁴
If you still disagree, you can seek judicial review in chancery or circuit court.

Evidence wins appeals. Recent comparable sales showing a lower value carry far more weight than a general sense the number is too high, and errors in the property record like incorrect square footage or lot size are easier still to fix. You can handle the first two levels without a lawyer, and most homeowners do.
