If your March mail included a DeKalb County assessment notice with a number well above what you remember from 2021, you are not imagining it. The county just closed out a four-year reappraisal cycle, and Assessor Shannon Cantrell told WJLE Radio that many landowners would be caught off guard by how much values had climbed since the last review. What surprised fewer people, because fewer people know to look for it, is that the tax rate fell hard enough to cancel most of that increase out.
That gap between the number on your notice and the number on your eventual bill matters if you are selling a home in Smithville this fall or buying one before the market cools for winter. A higher assessment does not automatically mean a higher tax bill, and it definitely does not mean a higher sale price. Treating those three numbers as one thing is the kind of mistake that shows up in a listing price or a buyer's monthly budget months after everyone involved should have known better.
The number on your notice isn't the number that sets your bill
Tennessee calculates property tax in three separate steps, and DeKalb County's own guidance spells out the formula plainly: appraisal times assessment rate equals assessed value, and assessed value times the tax rate equals what you actually owe. The reappraisal only touched the first number. What happens to your bill depends entirely on the third one, and that number wasn't finalized until months after the assessment notices went out.
Cantrell was direct about how this plays out for homeowners who don't follow the process closely.
"They get their tax notice October 1 and that's what really gets their attention if their taxes have gone up. Then they want to appeal it. But by that time the appeal for 2026 has already passed."
That's the trap. The appeal window opens in spring, before most people have connected their new assessed value to an actual dollar figure. By the time the bill arrives in October and the number finally means something, the chance to contest it is gone for the year.
Why the rate had to fall this far
Tennessee runs its reappraisal years through what the state calls a certified tax rate, sometimes shorthanded as truth-in-taxation. The idea is that a county-wide reappraisal shouldn't hand local government a windfall just because home values went up. The DeKalb County Assessor's office describes the mechanism directly on its site: the certified rate resets so that total tax collections stay roughly flat even when the combined value of every property in the county rises.
That's exactly what happened here. After appeals were heard through early June, the county's final certified rate landed at $1.5571 per $100 of assessed value, down from $2.51 the year before. The municipalities inside the county saw the same kind of reset:
| Jurisdiction | Previous Rate | New Certified Rate (2026-27) |
|---|---|---|
| DeKalb County | $2.51 | $1.5571 |
| City of Smithville | $0.7523 | $0.5199 |
| Town of Liberty | $0.1422 | $0.0793 |
| Town of Alexandria | $0.6233 | $0.4065 |
Every rate dropped by roughly the proportion assessed values rose, which is the whole point of the certified rate process. As Cantrell put it, most property owners will end up paying close to what they paid the year before, because the county and cities are collecting about the same total revenue either way.
What this actually changes if you're pricing a home this fall
Here's where it gets relevant to anyone with a closing date on the calendar. A DeKalb County assessed value is a tax instrument, not a market opinion. It reflects what the assessor's office believes a property was worth as of January 1, 2026, using recent sales and market trends across the whole county, not a comparative analysis of your specific street. If your assessed value jumped since 2021, that tells you the broader market moved, but it says nothing precise about what a buyer will actually pay for your particular home this September.
Sellers sometimes reach for a fresh, higher assessment as an anchor for their listing price. Buyers sometimes do the opposite and treat a lower assessed value as proof a home is underpriced. Neither read holds up on its own, because reappraisal values are calculated on a four-year lag and averaged across a wide range of comparable sales, while a listing price needs to reflect what's happening on a specific street this month, with the specific condition and features of that home. Assessed value is useful context. It is not a substitute for a current comparative market analysis.
The appeal window is already closed. Here's what's actually next.
For 2026, the process has run its course. Informal appeals were open from March 30 through April 10, and the DeKalb County Board of Equalization heard formal appeals the first week of June. If you didn't raise a concern about your assessed value during either window, that door is shut until next year's appeal season, regardless of what your October bill shows.
What's left on the calendar is the October 1 mailing, when the county sends out the actual tax notice tied to the new certified rates. For most homeowners, based on what the assessor's office has said publicly, that number should land close to last year's bill. If it doesn't, and you believe your property was overvalued relative to comparable sales, your options at that point are limited to whatever the county's process allows outside the normal appeal calendar, which is worth a call to the Assessor's office at 615-597-5925 rather than a guess.
What this means if you're buying or selling before then
A few practical notes worth carrying into a fall transaction:
- If you're listing a home, don't let this year's assessed value do the pricing work. Ask for a comparative market analysis based on actual recent closings in Smithville, not the county's four-year reappraisal number.
- If you're buying, understand that DeKalb County's assessed values were recalculated as of January 1, 2026. A property that looks cheap relative to its assessment isn't automatically underpriced, and one that looks expensive relative to its assessment isn't automatically overpriced.
- If you're budgeting for a purchase, expect your future tax bill to track closer to the new certified rates in the table above than to a straight-line projection off the old rate and the new higher assessed value. Multiplying an old rate by a new assessment overstates what you'll actually owe.
- If a seller's disclosure or listing sheet references an assessed value, ask when that value was set and whether it reflects the 2026 reappraisal or an earlier cycle. The two can tell very different stories about the same property.
Frequently asked questions
Does a higher assessed value mean my home is worth more on the market? Not directly. The reappraisal reflects market trends across DeKalb County as of January 1, 2026, not a specific analysis of your home compared to recent sales on your street. A current comparative market analysis is a better guide to what a buyer will actually pay.
Can I still appeal my 2026 property assessment? The informal appeal window and the County Board of Equalization's formal session for 2026 have already closed. If you have concerns about your assessment, contact the DeKalb County Assessor's office directly to ask what options remain outside the standard calendar.
Why did the tax rate drop so much if my assessed value went up? Tennessee's certified tax rate process is designed so a reappraisal doesn't automatically raise total tax collections. When countywide property values rise, the rate is recalculated so the county and cities collect roughly the same total revenue as the year before, which is why DeKalb County's rate fell from $2.51 to $1.5571 per $100 of assessed value this cycle.
