Watching headlines about soaring 2025 values and wondering what that means for your NorthShore tax bill? You are not alone. Property taxes can feel opaque, especially when both the City of Chattanooga and Hamilton County rates apply. In this guide, you will learn how your bill is calculated, what changed with the 2025 reappraisal, key deadlines, appeal steps, and relief options for NorthShore homeowners. Let’s dive in.
What changed in 2025
Hamilton County completed a countywide reappraisal effective January 1, 2025, with the assessor reporting large value increases around 56% to 60% on average. You can review reappraisal information and key dates on the Assessor’s page. (Hamilton County Assessor of Property)
To offset higher values, Tennessee requires a revenue‑neutral certified tax rate in reappraisal years. For 2025, Hamilton County’s certified rate was about $1.5157 per $100 of assessed value, and Chattanooga’s was reported near $1.55 per $100. Combined, that is roughly $3.06 per $100 of assessed value for a NorthShore homeowner if both certified rates apply. Local leaders also discussed whether to adopt rates above the certified level.

How Chattanooga property taxes are calculated
Appraised to assessed value
The Assessor sets your appraised value. Tennessee converts that to assessed value using set percentages. For residential property, assessed value equals 25% of appraised value. You can look up your parcel’s appraised and assessed values using the county search tool. (Assessor parcel search)

City and county tax rates
Hamilton County, the City of Chattanooga, and any applicable districts set rates per $100 of assessed value. In a reappraisal year, a certified tax rate is calculated so local governments do not receive an automatic windfall from higher values. Municipalities may accept the certified rate or hold hearings and adopt a different rate. (Certified rate overview)
Example for a NorthShore home
- Formula: (Appraised value × 25%) ÷ 100 × combined rate per $100 assessed
- Illustrative example: If your home appraises at $400,000, assessed value is 25% or $100,000. With a combined certified rate near $3.06 per $100, estimated tax is ($100,000 ÷ 100) × $3.06 = $3,060. Replace the appraised value and final adopted rates for your exact estimate.
Will your bill go up or down?
The certified rate lowers the nominal rate when values rise countywide, but individual bills can still change. What you pay depends on:
- How your value changed relative to the county average.
- Whether Chattanooga adopts a rate above the certified level.
- Any special district rates that apply to your parcel.
If your property’s value rose more than the county average, your bill may increase even with the certified rate. Local coverage provides context on value spikes and municipal debates in 2025. (Reappraisal impact background)
