If you only read one section, read this one.
Your 2026 Assessment Change Notice updates your property's appraised value to current market value as of January 1, 2026. It is not a tax bill. The dollar amount you owe will not be known until the County Commission and your city council adopt their tax rates this summer.
Three things to do right now
- Read your parcel data carefully. Check that the square footage, acreage, classification, and improvements listed match your actual property.
- Call the Assessor's office between May 4 and May 29. The number is (615) 444-8661. Call if you see anything wrong, or if you want to understand how the value was determined.
- Mark June 15 on your calendar. That is the tentative date for the County Commission's budget vote, where the actual property tax rate will be set.

What a reappraisal actually is.
A reappraisal is the process by which the Wilson County Assessor of Property updates the appraised market value of every parcel of real property in the county. Tennessee law requires it on a regular cycle so that values reflect current market conditions and the tax burden is shared fairly among property owners.
It is a valuation update. It is not, by itself, a tax increase. The reappraisal sets every parcel's value to fair market value as of January 1 of the reappraisal year. Between cycles, your appraisal generally does not change unless your property is remodeled, damaged, or changes use.
Why values jumped so much
Wilson County had been on a five-year reappraisal cycle. The values you have been paying tax on were set in 2021. The local real estate market has moved significantly in the five years since.
A reappraisal does not push values up. It catches the appraisal up to where the market already is. That does not make a 50, 60, or 70 percent jump on paper any easier to look at — but it does explain why the change is so large after five years with no update.
Reading your notice
| Parcel Information | Your parcel ID, address, classification, and acreage. Verify all of this is correct. Square footage or improvement errors are exactly the kind of thing the Assessor's office can correct quickly. |
| Appraised Value | The Assessor's estimate of what your property would sell for on the open market as of January 1, 2026. The headline number on your notice. |
| Assessment Rate | Tennessee assesses residential property at 25% of appraised value, by the state Constitution. Same for every residential property in the state. |
| Assessment | Appraised value × 25%. This is the number a tax rate gets applied to. A home appraised at $400,000 has an assessment of $100,000. |
| Greenbelt Appraised Value | If you qualify for Tennessee's Greenbelt program (agricultural, forest, or open space land), your property is assessed at use value rather than full market value. Contact the Assessor for the application. |
Three numbers that get confused all the time
| Appraised Value | What the Assessor estimates your property would sell for. Set during reappraisal. |
| Assessment Rate | 25% for residential. Set by the Tennessee Constitution. |
| Assessment | Appraised value × 25%. The number a tax rate gets applied to. |
| Tax Rate | Set by the County Commission and city councils each summer. |
| Tax Bill | Assessment × tax rate ÷ 100. Mailed by the Trustee in October. |
Three decisions in three different rooms.
Most of the confusion over what is happening to your tax bill comes from collapsing three separate decisions into one. They are made by different people in different rooms at different times. Untangling them is the key to understanding the system.
- The Assessor The Wilson County Assessor of Property sets your property's appraised value to market. The Assessor does not set tax rates and does not decide how much revenue the county will collect. The Assessor estimates value, period.
- Truth in Taxation After every reappraisal, state law mandates the recalculation of a "certified tax rate" to keep total revenue roughly flat. This calculation happens in the background. It is not optional. It sets the floor for the conversation about what rate to adopt.
- The Commission and City Councils The Wilson County Commission, plus your city council if you live inside Lebanon, Mt. Juliet, or Watertown, adopt the actual property tax rate every summer in the budget process — typically in June or July. They can adopt the certified rate (revenue stays roughly flat) or vote to adopt a higher rate (which is a tax increase).
Truth in Taxation: a guardrail, not a guarantee
Tennessee has a law commonly called Truth in Taxation. After every county-wide reappraisal, it requires the County and the cities within it to recalculate something called the certified tax rate.
The certified tax rate is the rate that would generate roughly the same total property tax revenue as the prior year, given the new appraised values. So if total appraised value across the county rises by 50 percent, the certified rate falls by roughly the same proportion to keep total revenue flat.
This is a guardrail, not a guarantee. Truth in Taxation prevents reappraisal from being an automatic countywide tax increase. It does not guarantee your individual bill stays the same.
Why a higher value doesn't always mean a higher bill
- How your property's value moved compared to the county average. If yours rose faster than average, your share of the total grew. If it rose slower, your share shrank.
- Whether the Commission or city councils adopt a rate above the certified rate. They can. State law requires public hearings before they do, but the option is on the table every summer.
- Other charges on the bill — solid waste, special school district levies, or municipal fees, set separately.
How the math actually works
Worked example: home appraised at $400,000
- Appraised value: $400,000
- Assessment: $400,000 × 25% = $100,000
- If county tax rate is $2.00 per $100, county tax = $100,000 × $2.00 ÷ 100 = $2,000
- Add city tax (if applicable) and any special levies for the total
If you live inside a city
Residents of Lebanon, Mt. Juliet, and Watertown pay both county property tax and city property tax. The county and the city each set their own rate independently, on their own timelines.
If you live inside city limits, you should pay attention to both the County Commission's rate vote (tentatively June 15) and your city council's rate vote, which typically happens later in the summer.
What's happening, when, and your role at each step.
| Date | What happens / what to do |
|---|---|
| May 4 to May 29 | Discussion window — call the Assessor with questions or corrections. |
| Late May | Certified rate published. The state Comptroller calculates the revenue-neutral baseline. |
| First business day in June | Board of Equalization opens. Formal appeals begin and the board stays in session as needed. |
| June 15 (tentative) | Wilson County budget vote. Mayor presents the budget and Commission votes on the tax rate. |
| July 1 | New 3-year reappraisal cycle begins. Smaller, more frequent updates going forward. |
| July to September | Cities set their tax rates. Lebanon, Mt. Juliet, and Watertown vote separately. |
| August 1 (or 45 days after BoE) | State Board appeal deadline. Last day to escalate beyond the county. |
| August 6 | Election Day. Wilson County Commission elections. |
| Mid-October | Tax bills are mailed by the Wilson County Trustee. |
| October to early April | Tax relief application window — for seniors, disabled, and disabled veterans. |
| End of February | Pay-without-interest deadline. After this, interest accrues on unpaid bills. |
June 15: the most important date
Most people stop paying attention after their assessment notice arrives. Do not stop here. The June 15 meeting is when the actual tax rate gets set.
At Wilson County's tentatively scheduled June 15 meeting, the County Mayor presents the proposed budget and the Commission votes on the tax rate, all in the same session. That schedule is tight. It compresses the public's window to absorb the proposal and make their voices heard. Residents who want to weigh in need to be ready before they walk into the room.
Wilson County Commission typically meets the third Monday of each month at the Wilson County Courthouse, 228 East Main Street, Lebanon. Meetings are open to the public. To find out who your district's commissioner is, visit wilsoncountytn.gov/222/County-Commission.
What happens after June 15
Once the County Commission has voted, the city councils for Lebanon, Mt. Juliet, and Watertown will go through their own budget processes and adopt their own tax rates. These typically wrap up by the end of summer.
By mid-October, the Wilson County Trustee will mail tax bills with the actual dollar amounts. Bills are due starting the first Monday in October and can be paid without interest through the last day of February of the following year. Payments can be made at the Trustee's Office, at any Wilson Bank and Trust branch, at any Pinnacle Bank branch, or online at citisenportal.com/Search/WilsonCountyTrustee.
The move to a three-year cycle
In March 2026, the Wilson County Commission voted to move from a five-year reappraisal cycle to a three-year cycle, beginning July 1. The next full reappraisal under the new schedule would happen in 2029.
The argument for shorter cycles is that smaller, more frequent value adjustments are easier on owners than one large jump every five or six years. Whether residents agree with the change is a fair conversation to keep having with your commissioners.
Three steps. Most resolve at step one.
If the value on your notice does not reflect what your property would actually sell for, or if it is out of line with comparable nearby homes, you have the right to appeal. The process has three steps. Most appeals can be resolved at step one.
Step 1 · Informal discussion with the Assessor
When: May 4 through May 29. How: Call (615) 444-8661 or visit 228 East Main Street, Room 4, Lebanon. Many issues are resolved on the phone or at the front desk.
What to have ready
- Your notice, with the parcel ID handy
- A list of any factual errors on the parcel record (square footage, acreage, classification, room count, improvements that no longer exist or additions that were not picked up)
- Comparable sales — recent sale prices of similar nearby properties, ideally within the last six to twelve months. Three to five comps is plenty. Zillow, Redfin, or the Wilson County parcel viewer all work
- Photos of any condition issues — foundation problems, deferred maintenance, drainage issues, roof or structural damage
What to ask
How was this value determined? What comparable sales were used? Are the recorded improvements accurate? If the answer reveals an error, staff can usually correct it on the spot.
Get it in writing
Ask the Assessor's staff to document your call in their system. Ask if they have a reference or case number for the conversation. If your concerns will not be resolved on the phone, ask specifically how to formally request a Board of Equalization hearing.
Step 2 · Wilson County Board of Equalization
When: By state law, the County Board of Equalization convenes the first business day in June and remains in session as needed to hear appeals. About ten days before, the Assessor publishes a public notice in the local newspaper with the meeting dates, time, and location.
How to request a hearing: Appointments are normally requested by phone or in person at the Assessor's office during the last week of May or the first week of June. If you have already started the process at step one, the Assessor's staff will help you schedule.
What to expect: You request an appointment, present your case, and the board issues a decision usually before the end of June. You can represent yourself. You do not need a lawyer. You can also send a family member, an attorney, or an authorized agent in your place.
Evidence that helps most
- Comparable sales of similar properties in your neighborhood, within the last 6 to 12 months
- Photographs of property condition issues
- Documentation of factual errors on the parcel record (the easiest type of correction to win)
- Recent appraisals or your own purchase price, if recent
- Professional inspection reports
Step 3 · Tennessee State Board of Equalization
When: The deadline is August 1 of the tax year, or 45 days after notice of the County Board's decision is sent — whichever is later. The decision letter from the County Board will include directions on how to file.
Tips for a successful appeal
- Start early. The window closes faster than you think.
- Be specific. "This value is too high" is harder to win than "This value is $50,000 above three comparable sales on my street in the last six months."
- Bring the paperwork. Write down what you say, get reference numbers, and follow up in writing.
- Stay polite. The staff is dealing with thousands of frustrated calls. You will get more done with patience than with anger, even when the anger is justified.
- Do not expect the appeal to lower your tax bill directly. The appeal can lower your appraised value, which can affect your bill — but the rate decision happens separately.
The senior tax freeze most people don't know about.
Tennessee and Wilson County run several programs that can reduce or freeze your property tax bill. Most residents do not know about them. They are administered through the Wilson County Trustee's Office at 228 East Main Street, Room 102, Lebanon. If you or a neighbor might qualify, this is the most useful section of this entire guide.
Property Tax Freeze · Wilson County · Age 65+
Wilson County has adopted the Property Tax Freeze Program for residents 65 and older. If you qualify and apply, your property tax on your principal residence is frozen at the base year amount. As long as you continue to qualify, that amount generally does not change going forward — even if the rate goes up or there is another reappraisal in the future.
Eligibility
- You must be 65 or older
- Household income at or below $63,470 for tax year 2026 (raised from $51,790)
- The property must be your principal residence
- The freeze applies to the residential portion of the property and up to 5 acres for farm or Greenbelt properties
How to apply
Apply through the Wilson County Trustee's Office at (615) 444-0894. You must reapply each year. Bring proof of age (driver's license or birth certificate), proof of income (Social Security statement, pension records, tax returns), and proof of residency.
State Property Tax Relief Program
Wilson County also participates in Tennessee's state-administered Property Tax Relief Program. There are three categories of eligibility, each with its own rules.
Category 1 · Elderly low-income homeowners
- Must be 65 or older
- Household income at or below approximately $37,530 for 2026
- Relief on the first $30,000 of property market value
- State reimburses up to approximately $27,000 of value
Category 2 · Totally and permanently disabled homeowners
- Must be totally and permanently disabled
- Same income test as the elderly program
- Relief on the first $30,000 of property market value
Category 3 · Disabled veterans and surviving spouses
- No income test
- Relief on the first $175,000 of property market value
- Eligibility requires documented service-connected total and permanent disability, or surviving spouse status under specific circumstances
How and when to apply
Applications are filed each year through the Trustee's office after you receive your tax bill in October. The deadline is typically about 35 days after the delinquency date — usually early April.
Combining the programs
The Property Tax Freeze and the state Tax Relief Program are separate but compatible. You can be on both. Approval for Tax Relief as a low-income elderly recipient counts as evidence of age and income for the Tax Freeze, but you still need to file a separate application for the freeze. Ask the Trustee's office to walk you through both.
If you pay through a mortgage escrow
Your servicer will adjust your monthly mortgage payment in the fall when the new bill is calculated. You can call your servicer in late summer to plan ahead. You still have the right to appeal the value, regardless of how the bill is paid.
Where and how to pay your tax bill
Once your bill arrives in October, you can pay at the Trustee's Office (228 East Main Street, Room 102, Lebanon), at any Wilson Bank and Trust branch, at any Pinnacle Bank branch, or online at citisenportal.com/Search/WilsonCountyTrustee. Bills can be paid without interest from mid-October through the last day of February.
Payment plans and hardship options
If you are struggling to pay your bill, contact the Wilson County Trustee's Office directly at (615) 444-0894. They can discuss payment options and help you understand the timeline of interest accrual after February. Do not let a bill go unpaid without first asking what your options are.
If you are a renter
Property taxes are generally passed through to renters as part of rent over time. If your landlord raises rent in response to a higher tax bill, the law generally allows that — though when and how depends on your lease. If you are on a long-term lease, check the terms. If you are month-to-month, expect any increase to come with the legally required notice period.
