Rate Breakdown

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

How Property Tax Works in Mcnairy County

Property tax in McNairy County is determined by a systematic assessment process. The County Property Assessor is responsible for discovering, listing, and valuing all taxable property. Every five years, the state conducts a reappraisal to ensure that property values reflect current market conditions. Once the appraised value is established, it is multiplied by the assessment ratio—set by Tennessee state law at 25% for residential and commercial property—to determine the "assessed value." The local County Commission then sets the tax rate (often referred to as the millage rate), which is applied to the assessed value to calculate your annual tax bill.

Available Exemptions

Tennessee offers several property tax relief programs designed to support specific populations. Eligibility is typically based on income, age, or disability status. Available exemptions include:

• Property Tax Relief Program: Available to low-income elderly homeowners (age 65 and older) and disabled homeowners who meet specific income requirements set by the state.
• Disabled Veterans Property Tax Relief: Provides tax relief for disabled veterans or their surviving spouses, provided the veteran has a service-connected disability as determined by the U.S. Department of Veterans Affairs.
• Tax Freeze Program: Allows qualified senior citizens (age 65 and older) to "freeze" the tax amount on their primary residence at the base year amount, preventing increases due to rising property values.

Residents are encouraged to contact the McNairy County Trustee’s office to confirm current income thresholds and application deadlines for these programs.

Payment Schedule & Deadlines

Property taxes in McNairy County are due annually. Taxes become payable on the first Monday in October. To avoid penalties and interest, the full amount must be paid by the last day of February of the following year. If payment is not received by the deadline, interest accrues at a rate of 1.5% per month. While McNairy County generally requires annual payments, some taxpayers may be able to make partial payments throughout the year; however, these must be finalized by the February deadline to prevent the account from becoming delinquent and subject to legal collection proceedings.

Appealing Your Assessment

If you believe your property’s appraised value is inaccurate, you have the right to appeal. The process begins with an informal review with the McNairy County Assessor of Property. Should you remain dissatisfied with the results, you may file a formal appeal with the County Board of Equalization. This board meets during the month of June to hear property owner concerns. It is recommended that you provide supporting evidence, such as recent appraisals, photographs of property conditions, or sales data of comparable properties in your area, to substantiate your claim for a valuation adjustment.
