Rate Breakdown

Property taxes in Cannon County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Cannon County

Property taxes in Cannon County are determined by a multi-step process involving the assessment of your property’s value and the application of a local tax rate. The Cannon County Assessor of Property is responsible for identifying, listing, and valuing all taxable property. Every five years, the state conducts a reappraisal to ensure assessments reflect current market values, though interim adjustments may occur for new construction or major improvements.

Once the Assessed Value is determined—calculated by multiplying the Appraised Value by the state-mandated assessment ratio (25% for residential and commercial property)—the Cannon County Commission sets the tax rate, often referred to as the millage rate. This rate is expressed in dollars per $100 of assessed value. To estimate your annual tax liability, multiply your assessed value by the current county tax rate and divide by 100.

Available Exemptions

Tennessee offers several property tax relief programs designed to assist eligible homeowners. These programs are administered by the state and may reduce the total tax burden for qualifying individuals:

• Property Tax Relief Program: This program provides financial assistance to low-income elderly (65+), disabled homeowners, and disabled veterans. Eligibility is based on total annual household income.
• Tax Freeze Program: Qualified seniors (65+) may be eligible to "freeze" the tax amount on their primary residence at the base year level, preventing future increases in property taxes despite rising property values.
• Disabled Veterans Exemption: Veterans with a 100% permanent and total service-connected disability, or those who are paraplegic, may qualify for a significant exemption on the value of their primary residence.

Applicants must reapply annually for these programs through the Trustee’s office to maintain eligibility.

Payment Schedule & Deadlines

Property taxes in Cannon County are due annually. Typically, tax notices are mailed in October, and payments are considered current through the last day of February of the following year.

• Deadline: All property tax payments must be received or postmarked by February 28th to avoid interest and penalties.
• Late Penalties: Beginning March 1st, interest accrues on unpaid balances at a rate of 1.5% per month (18% annually).
• Delinquency: If taxes remain unpaid beyond the grace period, the property may become subject to legal action, including tax liens or potential sale at a delinquent tax auction.

Homeowners are encouraged to pay early to avoid end-of-season processing delays.

Appealing Your Assessment

If you believe the appraised value of your property is inaccurate or exceeds its fair market value, you have the right to appeal. The process begins with an informal review with the Cannon County Assessor’s office. If you are unsatisfied with the outcome of the informal review, you may file a formal appeal with the Cannon County Board of Equalization. This board holds hearings to review evidence, such as recent sales of comparable properties or independent appraisals, to determine if an adjustment is warranted. Please note that appeals must be filed within the designated window following the notice of assessment.
