How Property Tax Works

Cannon County, Tennessee operates on a property tax system that serves as the primary funding mechanism for essential local services including public schools, road maintenance, law enforcement, emergency services, and general county operations. Property owners pay taxes based on their property's assessed value multiplied by the applicable tax rate, which varies depending on the specific location within the county due to different special taxing districts and municipal boundaries.

The effective property tax rate in Cannon County for fiscal year 2024-2025 is $1.596 per $100 of assessed value, though actual rates may differ based on your property's location within various special taxing districts. Tennessee assesses residential property at 25% of appraised market value, meaning a home valued at $400,000 would have an assessed value of $100,000 for tax calculation purposes. Property owners should note that tax rates and available credits can vary significantly depending on whether their property falls within municipal boundaries or special service districts within the county.

When Are Property Taxes Due?

For the 2025/2026 tax year in Cannon County, property taxes are due in two installments:

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.

Section 4

Supplemental Tax Bills

Supplemental taxes in Cannon County are additional property tax bills issued when there are mid-year changes to a property's assessed value or ownership. Common triggers include new construction completion, property improvements that increase value, change of ownership, or correction of assessment errors discovered after the main tax roll is finalized.

Supplemental taxes are calculated by determining the difference between the old and new assessed values, then applying the current tax rate to that difference. The tax is prorated based on the number of months remaining in the fiscal year after the change occurs. For example, if you complete a $50,000 home addition in January (midway through the fiscal year), the supplemental tax would be calculated on the increased assessed value ($50,000 x 25% assessment ratio = $12,500 additional assessed value) multiplied by the tax rate, then prorated for the remaining months of the fiscal year.

Escrow & Property Taxes

Most mortgage lenders in Cannon County require property tax escrow accounts, where monthly mortgage payments include a portion set aside for property taxes. Lenders typically collect 1/12 of the estimated annual tax bill each month, plus a cushion amount allowed by federal law. The lender pays your property tax bill directly to Cannon County when due.

Property tax bills in Cannon County are typically mailed in late summer, with the first installment due September 1st and the second installment due December 1st. If your property taxes are escrowed, verify that your lender receives and pays these bills on time. You should receive an annual escrow statement from your lender showing the account activity and any adjustments needed. If your property taxes increase significantly due to reassessment or rate changes, your lender may increase your monthly escrow amount or require you to make up any shortage over 12 months.

Frequently Asked Questions

Q: When are property taxes due in Cannon County? A: For fiscal year 2024-2025, the first installment is due September 1, 2024, and the second installment is due December 1, 2024. Taxes become delinquent if not paid by these dates.

Q: What tax credits are available and how do I apply? A: Tennessee offers various tax relief programs including homestead credits for qualifying homeowners, elderly/disabled tax relief, and veterans' exemptions. These require separate applications and are NOT automatic. Contact the Cannon County Property Assessor's office for applications and eligibility requirements.

Q: How does the homestead credit work? A: The homestead credit limits the annual increase in assessed value for qualifying owner-occupied homes, typically capping increases at a certain percentage. This credit requires filing an application and proving residency. It does not reduce your home's market value but limits assessment growth over time.

Q: How often are properties reassessed in Cannon County? A: Tennessee requires county-wide reappraisals every 4-6 years. Between reappraisals, individual properties may be reassessed due to improvements, sales, or other changes. Property owners receive notice of assessment changes and have appeal rights.

Q: What are the penalties for late payment? A: Cannon County charges interest and penalties on delinquent property taxes. Contact the County Trustee's office for current penalty rates and collection procedures.

Q: Can I pay property taxes online? A: Check with the Cannon County Trustee's office for available online payment options and accepted payment methods.

Q: Why did my tax bill increase when tax rates didn't change? A: Tax increases can result from higher property assessments, new special district taxes, or loss of previous tax credits. Your property may have been reassessed at a higher value even if tax rates remained constant.

Q: How do special district taxes affect my bill? A: Properties in fire districts, utility districts, or other special taxing districts pay additional taxes beyond the base county rate. These vary by location and the services provided by each district.
