Union County Property Assessor 2026: Search & Tax Records

by
Union County TN Property Assessment Guide 2026

Search Union County Tennessee Property Records, Parcel Maps and Assessments

Union County property research starts with the Assessor of Property, but tax bills and recorded deeds belong to different offices. The Assessor maintains appraisal, assessment, parcel-map, ownership, sale and building information. The County Trustee collects real and personal property taxes. The Register of Deeds records deeds, trust deeds, liens, releases, plats and other legal instruments.

This 2026 guide shows how to search Tennessee Property Assessment Data by owner, address or parcel ID, use advanced map/group/parcel fields, read January 1 owner versus current owner, understand Tennessee’s 25% residential assessment ratio, calculate a tax estimate, research Greenbelt, use Union County’s $38,470 senior tax-freeze limit, handle assessment appeals and find the right office for permits, 911 addresses, taxes and deeds.

What Union County Property Owners Should Know Right Now

Tax year 2026 assessment data is available, but Union County’s 2026 property-tax notices are not normally mailed until late September. The Trustee says annual tax notices are normally sent in late September, remain payable through the end of February and become delinquent March 1.
Searching a 2026 parcel Use Tennessee Property Assessment Data and select Union County. The current state database supports owner, property address and parcel-ID searches.
2025 tax still unpaid Taxes for the preceding year became delinquent March 1, 2026 under the normal Tennessee schedule. Ask the Trustee for the live amount rather than relying on an old bill.
2026 tax bill not received yet In August, that can be normal because Union County says tax notices are usually mailed in late September.
2026 database clue: Tennessee Property Assessment Data identifies Union County as county number 087 and current Union County parcel records show tax year 2026. State parcel records also identify the county’s reappraisal year as 2022.
Use the correct office

Assessor of Property vs Trustee vs Register of Deeds

Assessor of Property

  • Appraised property value
  • Assessed value and classification
  • Parcel ownership and maps
  • Sales and building characteristics
  • New deeds entered into assessment system
  • Business tangible personal property
  • 911 addresses for new construction
  • County building permits

County Trustee

  • County property-tax collection
  • Real and personal property taxes
  • Online, mail and counter payments
  • Partial in-office payments
  • Tax Relief applications
  • Property Tax Freeze administration
  • Delinquent account questions
  • Tax-payment records

Register of Deeds

  • Warranty and quitclaim deeds
  • Trust deeds and releases
  • Liens and foreclosure notices
  • Plat maps and easements
  • Affidavits and heirship deeds
  • Restrictions and rights-of-way
  • Greenbelt recordings
  • Property-fraud alerts
Critical routing rule: The Assessor calculates property appraisal and assessment. The County Commission sets the county tax rate. The Trustee collects the tax. The Register records legal real-estate instruments.
State terminology differs: Tennessee calls this office the Assessor of Property. Florida typically uses a Property Appraiser. For a comparison of the Florida parcel-search/value system, see the existing St. Johns County Property Appraiser guide.

Six Fields to Verify Before Relying on a Union County Parcel

County Confirm Union / 087.
Parcel ID Match exact identifier.
Property address Confirm location.
Owner Compare Jan. 1/current.
Classification Residential, farm, etc.
District Verify taxing location.
Do not use an assessment page as a deed. The parcel database is designed for property assessment. If legal ownership, title or an encumbrance matters, verify the recorded instrument through the Register of Deeds.
A Tennessee database detail many users miss

January 1 Owner vs Current Owner

Tennessee assessment records can show both a January 1 Owner and a Current Owner. These can legitimately differ after a property sells during the tax year.

January 1 Owner Tennessee’s assessment date is January 1. Assessment rolls and tax maps are based on the property status on that date.
→
Recorded Sale / Deed A later transaction can appear in the parcel’s sales section with date, instrument and book/page information.
→
Current Owner The current-owner field may update after the Assessor processes the newer deed information.
Buyer workflow: Match the newest sale date and book/page reference with the Register of Deeds record, then compare the current owner shown in TPAD. This helps distinguish a legitimate midyear ownership change from an outdated record.

How to Use TN Property Viewer for Union County

The Tennessee Property Viewer works with the Comptroller’s Property Assessment Data system. It lets users search, select a parcel on the map, view basic information and open the more detailed assessment record.

Open TN Property Viewer. Go to Tennessee Property Viewer.
Select Union County. Set the county before entering search information.
Search owner, address or parcel ID. The current viewer supports all three through its primary search field.
Use partial terms when useful. The state viewer supports partial owner, street and map-number search criteria.
Select the parcel from search results. The viewer highlights and zooms to the parcel and displays basic property information.
Open detailed Property Assessment Data. Use the link in the parcel panel for the most detailed property assessment record.
Turn map layers on and off. Use Layer Control to avoid clutter and focus on relevant parcel context.
Print only after verifying the correct parcel. The viewer includes a print function for the map and parcel details.
GIS boundary warning: A parcel viewer is not a legal survey. For boundary lines, encroachments, easements or acreage disputes, compare the deed and recorded plat and use a licensed surveyor when necessary.

Market Appraisal, Use Value and Assessed Value Explained

Land market value Appraised market value assigned to the land.
Check acres, location and land classification.
Improvement value Appraised value assigned to buildings and qualifying improvements.
Check building type, size and condition.
Total market appraisal Combined market appraisal before the statutory assessment percentage.
This is not the tax bill.
Assessment Appraisal multiplied by the statutory percentage for the property class.
Residential and farm are normally 25%.
Agricultural record: A qualifying Greenbelt parcel can display both Total Market Appraisal and Total Use Appraisal. The use-value figure reflects the property’s qualifying current agricultural, forest or open-space use rather than ordinary highest-and-best-use market value.

Tennessee annual assessment/tax sequence

Union County Property Assessment and Tax Calendar

Assessment date Ownership, assessment and tax-map status are tied to January 1.
Greenbelt First-time agricultural, forest and open-space applications are generally due.
Assessment notices Tennessee’s schedule targets completion of assessments and mailing of change notices.
County BOE County Boards of Equalization normally begin their session around June 1.
Union tax notices Trustee says county tax notices are normally mailed in late September.
Delinquency Unpaid preceding-year taxes become delinquent under the normal schedule.
State appeal timing: A further State Board of Equalization appeal from a County Board decision generally must be filed by August 1 of the tax year or within 45 days of the date notice of County Board action was sent, whichever is later.
Value and classification disputes

How to Appeal a Union County Property Assessment

Informal Assessor review Contact the Assessor first when a property characteristic, ownership entry, classification or appraisal appears wrong.
County Board of Equalization This is normally the first formal level for disputing a current-year property value or classification.
State Board of Equalization A taxpayer dissatisfied with the County Board decision can usually continue the appeal to the Tennessee State Board.
Search the 2026 parcel. Save the parcel ID, classification, land value, improvement value, total appraisal and assessment.
Identify the exact issue. Separate a market-value disagreement from an acreage, building, ownership or classification error.
Contact the Union County Assessor. Ask whether an informal review remains available and confirm the current County Board filing schedule.
Prepare objective evidence. Use comparable sales, photographs, surveys, building records, repair information or other issue-specific evidence.
File with the County Board when required. Tennessee generally requires the disputed assessment to go through the County Board before further appeal rights are preserved.
Read the County Board decision carefully. The date notice is sent matters for a later State Board filing.
Use the State Board deadline if continuing. The general state deadline is August 1 or 45 days from notice of County Board action, whichever is later.

Useful evidence checklist

  • Parcel ID and property address
  • Assessment/change notice
  • Current appraised value
  • Your opinion of value
  • Comparable sales
  • Condition photographs
  • Survey or acreage documents
  • Building measurements
  • Permit or demolition records
  • Recorded deed for ownership issues
Informal review is not automatically a formal appeal. Tennessee’s State Board warns that taxpayers normally must appeal to the County Board to preserve further appeal rights.
“I am calling about Union County parcel __________. The 2026 assessment record shows __________, but my evidence shows __________. Please confirm whether an informal review is available and the current deadline and procedure for a County Board of Equalization appeal.”
Union County Assessor Contact the office for the current local review and County Board schedule. State Board Value Appeals Review Tennessee’s appeal sequence, deadlines and exceptions.
Agricultural, forest and open-space land

Union County Greenbelt Property Records

Greenbelt is Tennessee’s Agricultural, Forest and Open Space Land Act program. Qualifying land is assessed using its current-use value rather than ordinary market value.

What to look for in the parcel record

  • Total Market Appraisal
  • Land Use Value
  • Total Use Appraisal
  • Agricultural or forest classification
  • Deed acres and land-code breakdown
  • Greenbelt-related deed/recording information
First-time deadline Tennessee requires first-time Greenbelt applications to be filed with the Assessor by March 15.
Forest land Qualifying forest land generally requires at least 15 acres plus sufficient tree growth and a forest management plan.
Open-space land Different statutory requirements apply and qualifying areas depend on planning designation.
Rollback risk: When Greenbelt land becomes disqualified, rollback tax can recapture some prior tax savings. Do not remove acreage, change use or transfer property without understanding the possible rollback consequence.
Late continuation: Tennessee allows a limited late route when a prior Greenbelt classification is being continued after a missed March 15 filing. The state guidance describes a 30-day period after disqualification notice plus a $50 late fee payable to the Trustee.
Open Tennessee Greenbelt Guidance Review agricultural, forest and open-space requirements, forms, filing deadlines and rollback rules.
Union County adopted the program in 2023

Union County Property Tax Freeze: 2026 Income Limit

2026 Union County Tax Freeze basics

  • Union County adopted the county Property Tax Freeze program in 2023.
  • The published 2026 income limit is $38,470.
  • The applicant generally must be age 65 or older by the end of the application year.
  • The property must be the applicant’s principal residence.
  • Income from all owners is considered under program rules.
  • The owner must apply and provide proof of age, ownership and income.
  • The freeze generally locks the property tax at a base amount rather than freezing the assessed value itself.
  • Annual reapplication is required.
Freeze does not stop assessments: The Assessor continues valuing the property. If the calculated tax becomes lower than the frozen amount, the taxpayer owes the lower amount and the freeze can be adjusted downward.
Improvements can change the frozen amount. The state program allows the base tax to be adjusted when improvements increase the property’s value.
2026 Tennessee Tax Freeze Review Union County’s participation, income limit and qualification rules. Apply Through Union County Trustee Ask the collecting office for current application documents and deadline guidance.
Different from the local Tax Freeze

Tennessee Property Tax Relief for Union County Homeowners

Tennessee also operates a state-funded Property Tax Relief program. It can help qualifying low-income elderly or disabled homeowners, disabled veterans and qualifying surviving spouses.

Elderly homeowner State-funded relief can apply when age, principal-residence and income requirements are satisfied.
Disabled homeowner Qualifying permanently disabled homeowners may apply under the state program.
Disabled veteran Tennessee provides special relief for qualifying disabled veterans and certain surviving spouses.
Disabled-veteran value limit: Tennessee’s current veteran guidance states that qualifying relief is calculated on up to the first $175,000 of market value of the primary residence.
Tax Relief is not a tax exemption. The state pays or reimburses qualifying property tax under the program. The owner still receives the tax bill and remains responsible for properly handling any balance due.
Tax Relief and Tax Freeze can coexist. Tennessee’s Tax Freeze rules state that the freeze program is in addition to the existing Property Tax Relief Program.
State Property Tax Relief Review the 2026 brochure, eligibility and application guidance. Union County Trustee Local collecting officials receive applications from taxpayers who may qualify.
County Trustee payment workflow

Union County Tennessee Property Tax Records and Payments

Union County Trustee Gina B. Gilbert collects county real and personal property taxes. The Trustee offers payment in person, by mail and online; partial payments are accepted when made in the office.

Find the Assessor parcel first. Copy the owner, parcel ID and property address from Tennessee Property Assessment Data.
Open the Union County Trustee page. Use Union County Trustee for current tax-payment instructions.
Use the county-linked online tax portal when paying online. The Trustee currently routes online payments to Union County Trustee property-tax search.
Verify the exact account before payment. Match owner, property location, tax year and amount due.
Review the convenience fee. The Trustee states that a convenience fee applies to online payments and that Union County does not receive that fee. Check the live payment screen for the current amount.
Consider an in-office partial payment if needed. Union County states that partial payments are accepted when payments are made in the Trustee’s office.
Save the receipt. Retain proof until the tax account reflects the payment.
Late September Union County tax notices are normally mailed.
Through February Annual county property taxes are normally payable through the end of February.
March 1 Unpaid taxes become delinquent under the county’s published schedule.
18-month collection transition: The Trustee says delinquent taxes remain in the Trustee’s office for 18 months. After that period, amounts due are transferred to the Clerk & Master for collection and a lawsuit is filed.
“I need the current tax status for Union County parcel __________ at __________. Please confirm the tax year, total amount due, any interest or collection status, and whether the account is still with the Trustee or has been transferred to the Clerk & Master.”
Legal recorded-property records

Union County Deeds, Trust Deeds, Liens and Plat Records

Register of Deeds Ann Russell records legal instruments affecting Union County property. These records are separate from the Assessor’s valuation database.

Ownership documents Warranty deeds, quitclaim deeds, heirship deeds and related conveyances.
Debt / lien documents Trust deeds, federal liens, state tax liens, fixture filings and releases.
Land-use documents Plat maps, easements, rights-of-way, restrictions and Greenbelt recordings.
Start with the Assessor parcel. Save the owner, Parcel ID and sale-book/page information when available.
Contact the Register of Deeds. Use the Union County Register of Deeds for current recording and record-access instructions.
Search or request the specific instrument. Provide owner names, deed type, approximate date, book/page reference or other available identifiers.
Compare legal description and parties. Do not assume a same-name document belongs to the correct parcel.
Use professional title help when required. The Register records documents but cannot provide legal advice or prepare documents for you.
Property-fraud protection: The Register of Deeds promotes a fraud-alert service that can notify property owners by email when a document or transaction is filed under a monitored name or business.
Alert does not automatically mean fraud. The Register notes that some notifications may simply reflect an address search or legitimate transaction. Verify the document before assuming criminal activity.
Unusual Union County office responsibility

Building Permits, New-Construction 911 Addresses and Septic Records

Unlike many counties where building permits are handled by a separate building department, Union County states that all county building permits must be purchased through the Assessor of Property’s office and are not offered online.

Identify parcel Find the property in TPAD and save the parcel ID and owner information.
Contact Assessor Ask what is required for the planned new construction.
Purchase permit in office Union County says building permits are not offered online.
Coordinate 911 address The Assessor also assigns 911 addresses for new construction.
Building permit Purchase at the Union County Assessor of Property office.
911 address New-construction addressing is handled through the Assessor’s office.
Septic files Union County directs septic-file questions to the Knoxville Field Office at 865-594-6035.
Do not use the parcel card as a building permit. Assessment data may describe buildings on the property but does not prove that a structure was permitted or approved under current building rules.
Mailing record maintenance

How to Correct a Union County Property Mailing Address

The Assessor’s official page provides a Change of Address Form because the assessment office tracks ownership and address information used in property records.

Search the parcel first. Confirm the owner, current mailing information and exact parcel ID.
Open the Union County Assessor page. Find the current Change of Address Form through Assessor of Property.
Provide every requested parcel and owner detail. The office needs enough information to distinguish the correct property from other accounts.
Do not treat a mailing-address change as a deed change. A new mailing address does not transfer legal ownership.
Check the property database again after processing. Allow administrative time, then confirm the new mailing information appears.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
