Carter County property tax runs $2.18 per $100 of assessed value, with bills due the first Monday in October and delinquent if unpaid by March 1. If your property sits inside Elizabethton, Johnson City, or Watauga, you also owe that city’s rate on top of the county rate. A county-wide reappraisal is set for 2026, so appraised values (and the bills that follow from them) are likely to shift for many owners this cycle.
How Your Bill Is Calculated
Tennessee assesses property at a fixed percentage of its appraised value, and the percentage depends on how the property is classified. Residential and farm property is assessed at 25 percent of appraised value. Commercial and industrial property is assessed at 40 percent. Tangible personal property used in a business is assessed at 30 percent of its depreciated value.1Tennessee Comptroller of the Treasury. How to Calculate Your Tax Bill
From there the math is simple. Multiply the appraised value by the assessment ratio to get the assessed value, then multiply by the tax rate per $100. A home appraised at $200,000 has an assessed value of $50,000, and at the county rate of $2.18 per $100 the county tax comes to $1,090.2Tennessee Comptroller of the Treasury. Carter – County Assessment Info
Inside city limits, add the municipal rate:
- Elizabethton: $1.74 per $100, for a combined $3.92
- Johnson City: $2.3965 per $100, for a combined $4.5765
- Watauga: $0.57 per $100, for a combined $2.75
That same $200,000 home inside Johnson City would owe roughly $2,288 instead of $1,090.2Tennessee Comptroller of the Treasury. Carter – County Assessment Info The difference between living inside and outside city limits is not small.
To check your own appraised value, classification, and parcel ID, use the state’s Real Estate Assessment Data portal maintained by the Tennessee Comptroller’s office. You can search by owner name, address, or parcel ID.3Tennessee Comptroller of the Treasury.

When and How to Pay
The Carter County Trustee collects county property taxes. Bills become due on the first Monday in October and must be paid in full before March 1 to avoid penalties.5Tennessee Comptroller of the Treasury. Assessment Schedule That leaves roughly five months to pay.
The Trustee’s office accepts payments in person, by mail with a check or money order, or online through the county’s payment portal.6Carter County Government. Carter County Trustee Online card payments typically carry a convenience fee of around 2.5 percent, which goes to the payment processor rather than the county.
Tennessee law does not require county trustees to accept partial payments. A trustee may offer an installment plan if the office files an approved plan with the state Comptroller, but even on an installment arrangement the full balance must be paid before March 1. To find out whether Carter County currently offers installments, call the Trustee’s office at 423-542-1811.
What Happens If You Pay Late
Miss March 1 and interest starts at 1.5 percent per month on the unpaid balance. It accrues on March 1 and again on the first of each month afterward until the bill is paid.7Justia Law. Tennessee Code 67-5-2010 – Interest – Delinquent Taxes That works out to 18 percent per year. Taxes still unpaid after 13 months move to the Clerk and Master’s office for further collection.
Long enough unpaid, and the county can sell the property at a tax sale. The former owner keeps a right to redeem after the sale, but the window shrinks the longer the delinquency ran:
- Five years of delinquency or less: one year from the court order confirming the sale
- More than five but less than eight years: 180 days
- Eight years or more: 90 days
If you don’t pay the full redemption amount within the applicable window, the property transfers permanently to the purchaser.
Appealing Your Assessment
If you think the assessor overvalued or misclassified your property, start with the Carter County Board of Equalization. The board typically convenes beginning the first business day of June, and the assessor’s office posts the dates and procedures in advance. Bring evidence: recent comparable sales, an independent appraisal, photographs of the property’s condition, or documentation of anything that reduces market value.
If the county board rules against you, the next step is the Tennessee State Board of Equalization. The filing deadline is August 1 of the tax year or 45 days after the local board sends notice of its decision, whichever is later. The state uses an online filing system. An administrative judge hears evidence from both sides and issues a decision within 90 days.8Tennessee Comptroller of the Treasury. Value Appeals From there you can petition for review within 30 days or file in chancery court within 60 days of the State Board’s final order. Most homeowners resolve things at the county level.
Tax Relief and Freeze Programs
Tennessee funds state-level programs that reduce or reimburse part of what qualifying homeowners pay. All of them require an annual application filed through the Carter County Trustee’s office.
Elderly Low-Income Homeowners
If you’ll be 65 or older by December 31 of the tax year and your total household income falls below the annual threshold, you may qualify for reimbursement of all or part of your property tax. The base figure in the statute increases each year by the Social Security cost-of-living adjustment.9Justia Law. Tennessee Code 67-5-702 – Elderly Low-Income Homeowners For tax year 2026, relief applies to the first $32,700 of the home’s full market value. Household income counts all sources for everyone on the deed and their spouses, including Social Security, pensions, and investment income. The home must be your principal residence.
Disabled Homeowners
Homeowners who are totally and permanently disabled may qualify under a parallel program with the same income limits and market value caps. You’ll need documentation from a physician or the Social Security Administration.
Disabled Veterans
Veterans with qualifying service-connected disabilities get relief on the first $175,000 of their home’s full market value, regardless of income. Qualifying conditions include paraplegia or permanent paralysis of both legs, legal blindness, loss or loss of use of two or more limbs from a service-connected cause, 100 percent permanent total disability from having been a prisoner of war, or a permanent and total service-connected disability as determined by the U.S. Department of Veterans Affairs.10Justia Law. Tennessee Code 67-5-704 – Disabled Veteran’s Residence A dishonorable discharge disqualifies. Surviving spouses may qualify if they continue to meet ownership and residency requirements.
Property Tax Freeze for Seniors
Separate from the relief programs, Tennessee allows a tax freeze that locks your annual bill at its current amount so reappraisals and rate changes don’t push it up. The base amount only changes if you make improvements that raise the property’s value or if you move to a different home.11Tennessee Comptroller of the Treasury. Property Tax Freeze
Participation is optional at the county and city level, so not every jurisdiction offers it.11Tennessee Comptroller of the Treasury. Property Tax Freeze To qualify, you must be 65 or older by the end of the application year, own and occupy the home as your principal residence, and have household income under the limit for that year. For 2026, the statewide income threshold is $63,470, based on 2025 income. Call the Carter County Trustee’s office to confirm whether the freeze is currently available in your jurisdiction and to apply.
If You Own a Business
Business owners have a separate obligation. Every year you must file a Schedule B form with the county assessor listing all tangible personal property used in the business, including equipment, furniture, computers, tools, and other physical assets. The form is due by March 1.12Tennessee Comptroller of the Treasury. Tangible Personal Property
Skipping the filing is a costly mistake. A business that doesn’t return a schedule gets a forced assessment from the assessor, and forced assessments cannot be amended.12Tennessee Comptroller of the Treasury. Tangible Personal Property The assessor estimates your business assets, you’re taxed at 30 percent of that estimate, and you have no way to correct it. Filing accurately and on time is the only way to keep control over what you’re taxed on.
