Tax relief and valuation review

Protect your exemption and appeal rights.

A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Sullivan County Assessor of Property (Donna Whitaker).

Relief programs

What the local record says

Homestead filing

The filing guidance for this county is: Tennessee has no general homeowner homestead exemption. For tax year 2026, first-time Greenbelt applications are due March 15, 2026; State Board of Equalization property-tax exemption applications are generally due May 20, 2026; and state Tax Relief/Tax Freeze applications are filed with the county Trustee. Official program information: https://comptroller.tn.gov/office-functions/pa/property-taxes/property-tax-programs/tax-relief.html. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.

Open homestead application

Senior citizen tax relief

The Sullivan County Trustee administers Tennessee Property Tax Relief for qualifying elderly, disabled, disabled-veteran, and surviving-spouse homeowners. The official 2026 Comptroller participating-jurisdiction list does not list Sullivan County as a countywide local-option Property Tax Freeze county; confirm current eligibility with the Trustee.

Valuation cap or growth limit

No general Tennessee individual assessed-value cap was verified. Sullivan County's official Assessor page says the next countywide reappraisal is scheduled for 2027; Tennessee certified-tax-rate/revenue-neutral rules, Greenbelt, and any qualifying senior relief are separate protections.

Appealing an assessment

Build the objection around evidence and the notice date.

Calendar the window

Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.

Assemble support

Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.

File and preserve proof

Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.

The verified protest guidance for this county is: The Sullivan County Board of Equalization meets beginning June 1, 2026 for approximately two weeks. Appeal to the State Board by August 1, 2026 or within 45 days after the county-board notice, whichever is later; official guidance: https://comptroller.tn.gov/boards/state-board-of-equalization/value-appeals.html If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
