You’re sitting at the kitchen table, opening a piece of mail that looks suspiciously like a bill, and there it is: your property assessment. For most folks in Dickson County, this is the moment when the "tax man" suddenly feels very real. But honestly, most of what we think we know about the Dickson County Property Assessor is a little bit sideways.
First off, Jenny Heath Martin—who’s been the Assessor of Property here since 2016—isn't actually the one who decides how much you pay in taxes. I know, it sounds like a technicality, but it’s a big one. Her office’s job is basically to figure out what your house or land is worth if you sold it today. They "discover, list, and value" property. The actual tax rate? That’s on the County Commission. If your bill went up, it’s usually because the market went crazy or the local government changed the rate, not because the Assessor has a personal vendetta against your driveway.
The Reality of the Assessment Cycle
Tennessee law is pretty strict about how this works. In Dickson County, we don’t just guess every year. There's a cycle. Most counties operate on a 4-to-6-year reappraisal schedule to keep things fair. Between those big reappraisal years, your "appraised value" stays pretty much frozen unless you do something major, like adding a deck or a whole new garage.
During a reappraisal year, the office looks at every single parcel in the county. They aren't just looking at your specific house; they’re looking at what similar houses in Charlotte, Burns, or White Bluff sold for recently. It’s a massive data project. They use a system called Computer Assisted Mass Appraisal (CAMA). It sounds like something out of a sci-fi movie, but it’s basically just a giant database that helps ensure your neighbor with the same floor plan isn't getting a wildly different value than you.
Why Your "Taxable" Value Isn't Your "Market" Value
Here is where people get really confused. In Tennessee, you aren't taxed on 100% of your home's value. That would be brutal. Instead, we use "assessment ratios."
- Residential and Farm Property: 25% of appraised value.
- Commercial and Industrial: 40% of appraised value.
- Business Personal Property: 30% of appraised value.
So, if Jenny’s office says your home is worth $300,000 (the "appraised value"), your "assessed value" is only $75,000. That smaller number is what the County Commission applies the tax rate to. If you’re looking at your notice and seeing a number that feels way too low, don't panic—you’re likely looking at the 25% assessment, not the actual market value.

The Greenbelt "Secret" for Landowners
If you have a decent amount of land, you’ve probably heard of the Greenbelt Law. Officially, it’s the Agricultural, Forest, and Open Space Land Act of 1976. This is huge for Dickson County because we still have so much beautiful rural acreage.
Basically, if you have 15 acres or more that you’re using for farming or timber, you can apply to have that land valued based on its use rather than what a developer would pay for it. This can drop your tax burden significantly. However—and this is the "gotcha"—if you sell that land to a developer or stop farming it, you might have to pay "rollback taxes." That’s the difference between the savings you got and the full tax amount for the last three years. It’s a great deal, but it’s a long-term commitment.
How to Actually Appeal (And Win)
What if they got it wrong? It happens. Maybe they think you have finished basement square footage that’s actually just a crawlspace with a lightbulb. Or maybe they haven't noticed the sinkhole in the backyard that makes half your lot unusable.
- Informal Review: Start by just calling the office at (615) 789-7015. They’re located in the Administration Building in Charlotte. Sometimes a simple conversation and a few photos can fix a clerical error without any drama.
- County Board of Equalization: This board meets in the first two weeks of June. You have to make an appointment through the Assessor’s office. This is your formal "day in court" at the local level.
- State Board of Equalization: If you still aren't happy, you can go to the state level, but you usually have to start at the county board first.
Don't just go in and say, "My taxes are too high!" Everyone thinks their taxes are too high. Instead, bring evidence. Show them three houses nearby that sold for less than your appraised value. Bring a contractor’s estimate for that foundation repair you’ve been putting off. The board responds to data, not feelings.
Common Misconceptions About the Office
One thing that drives the staff crazy? People calling to pay their taxes there. The Assessor’s office does not collect money. That’s the Trustee’s job. Jenny Martin’s team handles the "what it’s worth" part; Glynda Pendergrass (the Trustee) handles the "here is the bill" part.
Also, the Assessor doesn't set the tax rate. That is a political decision made by the County Commission. If the county builds a new school or paves more roads, the Commission might raise the rate to pay for it. The Assessor’s job stays the same: just tell us what the property is worth.
Actionable Next Steps for Dickson County Owners
If you want to stay ahead of the game, don't wait for the tax bill in October.
- Check Your Data Now: Go to the Tennessee Comptroller’s "Real Estate Assessment Data" website. Search for your name in Dickson County. Make sure your square footage, acreage, and "improvements" (buildings) are listed correctly.
- Apply for Exemptions Early: If you’re over 65, a disabled veteran, or looking at the Greenbelt program, there are deadlines. Don't wait until June.
- Keep Records: If you do a major renovation, keep the receipts. If you have damage, take photos. These are your best friends if you ever need to challenge a value.
Understanding the Dickson County Property Assessor is really about understanding the difference between value and taxation. One is a math problem based on the market; the other is a budget problem based on what the county needs to run. By keeping an eye on your property’s "math," you ensure you’re only paying your fair share and not a penny more.
