Find the Right Union County Before You Search
Union County property searches are unusually easy to mix up because the same county name exists in several states. Start by identifying the state, then use the official assessor, tax, GIS or deed system built for that jurisdiction.
This guide focuses on the strongest current search intents—South Dakota, Oregon, New Jersey and North Carolina—and shows exactly which fields work, what the records mean, how to fix failed searches, where taxes are actually paid and which 2026 appeal rules apply.
Quick Answer: Which Union County Property Database Do You Need?
If the property is around Elk Point, North Sioux City or Dakota Dunes, use Union County, South Dakota. If it is around La Grande, use Oregon. If it is in Elizabeth, Linden, Plainfield, Westfield, Union Township or another New Jersey municipality, use Union County, New Jersey. If it is around Monroe, Indian Trail, Waxhaw or Weddington, use North Carolina.
Choose Your Union County by State and Nearby City
Do this before entering an owner name. A legitimate parcel found in the wrong state is still the wrong property.
South Dakota
Nearby places: Elk Point, Jefferson, North Sioux City and Dakota Dunes.
The county assessment office is called the Director of Equalization. Union County directs property-search users to Beacon.
Confirmed Beacon fields: Address, Parcel ID and Section/Township/Range.
Oregon
Nearby places: La Grande, Island City, Elgin and Union.
The county has a combined Assessor / Tax Collector office responsible for both assessment and tax collection.
New Jersey
Municipalities include: Elizabeth, Linden, Plainfield, Rahway, Summit, Westfield and Union Township.
The local municipal assessor performs assessment work. Confirm the municipality before searching statewide parcel or assessment data.
North Carolina
Nearby places: Monroe, Indian Trail, Waxhaw, Weddington, Stallings and Marvin.
Union County Tax Administration provides the Property Portal, while UC Atlas provides current interactive mapping.
How to Search the Correct Union County Property Record
Use this sequence before checking value, ownership, taxes, GIS or appeal information.
Confirm the state and municipality
Identify the state first. For New Jersey, also determine the municipality because local assessors maintain municipal assessment records.
Choose the record you actually need
Use the assessor or appraisal system for value and property characteristics, the tax collector or treasurer for payment status, GIS for mapping and the recorder or register of deeds for legal documents.
Start with one reliable search field
Use a parcel/PIN/account number when available. Otherwise begin with a simplified property address or an owner name only where the official system supports owner searching.
Reduce the search when no result appears
Remove ZIP code, punctuation, unit number and unnecessary street-direction wording. A partial street or owner name can work better than an over-formatted query.
Verify the matching parcel
Compare state, municipality, situs address, parcel identifier, owner display, legal-description clues and tax year before using the result.
Use the responsible office for the final action
Move to the tax office for payment, the recorder for legal title documents or the correct assessment-appeal authority when disputing value.
Search by Address, Owner Name, Parcel or Map
Jurisdiction |
Best search fields |
Micro-level search tip |
|---|---|---|
Union County SD |
Address, Parcel ID, Section/Township/Range |
On Beacon choose South Dakota → Union County, SD. The county does not explicitly list owner name among its three primary search fields. |
Union County OR |
County Property Records / account lookup |
Use the county-linked Property Records inquiry rather than a private property-value website. Tax and assessment information are handled by the same office. |
Union County NJ |
County, municipality, address, block and lot |
Use NJ Property Explorer for parcel identification. Owner availability may be affected by privacy protection or annual-data timing; use the municipal assessor when an owner-specific assessment question remains. |
Union County NC |
Owner name, Parcel ID, address |
The official Property Portal supports all three. If the property characteristics are wrong, the portal can also be used to request corrections. |

2026 county reappraisal work
The county’s current Director of Equalization information identifies Jefferson Township and Deer Run Development as the 2026 areas in its countywide reappraisal schedule. Property owners in an active review area should compare the parcel’s physical characteristics with the actual structures and report material factual errors.
Do not use Beacon as proof that taxes were paid
The Treasurer specifically instructs users not to rely on Beacon to confirm taxes paid or determine the exact amount currently due. Use the Treasurer’s live tax-payment system instead.

South Dakota 2026 Property Appeal Process
South Dakota’s official 2026 guide lays out a staged appeal process. As of August 2026, the ordinary spring deadlines below have passed.
Assessment notices were required to be mailed by March 1.
The local-board clerk had to receive the written appeal by March 12. A letter, email, signed PT17 or another written notification could qualify.
This was the 2026 filing deadline for owner-occupied status with the Director of Equalization.
Qualifying written appeals to the county auditor had an April 7 deadline.
A qualifying further OHE appeal had to be mailed or filed by May 15.
The state guide describes a 30-day court deadline after the applicable decision notice.
What must the written local appeal contain?
- Property owner’s name.
- Legal description of the property.
- A brief explanation of the appeal.
- Evidence supporting the requested change.
Do not skip the required board
The 2026 guide warns that a taxpayer who is required to appeal to the Local Board first can lose the right to proceed to later boards by skipping that stage. Nonresidents and owners in unorganized townships have different routing rules.
Official South Dakota Department of Revenue PDF Open 2026 Appeal GuideOregon: One Office Handles Assessment and Tax Collection
Union County, Oregon differs from South Dakota because the county combines the Assessor and Tax Collector functions.
Property Records Inquiry
Use the county-linked Records Inquiry system for assessment and property-tax account research rather than a private valuation database.
Tax maps and ORMAP
The Assessor / Tax Collector page provides tax-map resources and a route to Oregon’s ORMAP cadastral mapping system.
Real market value is not always taxable assessed value
Oregon property records can involve real market value, maximum assessed value and assessed value. Oregon generally taxes the applicable assessed value under its constitutional property-tax system, so multiplying the real market value by an internet “average tax rate” can produce a poor estimate.
Current Oregon value-appeal timing
For most property-value disputes, Oregon DOR says the owner files with the county Property Value Appeals Board after receiving the tax statement but before December 31, or the next business day when December 31 falls on a weekend or holiday.
After a PVAB value decision
For a property-value issue, Oregon DOR says an owner generally has 30 days from the board order to appeal to the Magistrate Division of the Oregon Tax Court. Some non-value issues, including exemption denial and omitted assessments, use different routes and can have a 90-day deadline.
Official Union County Oregon and Oregon DOR resourcesNew Jersey: Municipality First, Then Parcel or Assessment
Union County, New Jersey does not operate like a single-county assessor database. Property assessment begins with the local municipal assessor.
Best official route when you have an address
- Confirm that the property is in Union County, New Jersey.
- Identify the municipality—for example Elizabeth, Linden, Plainfield, Rahway, Summit, Westfield or Union Township.
- Use the official New Jersey Property Explorer to search by address, county, municipality, block and lot.
- Save the block and lot numbers.
- Use the municipality’s assessor for assessment-specific questions or corrections.
Why a recent buyer may not appear yet
The New Jersey Transparency Center says its annual property-tax data comes from local-assessor lists filed in January. Ownership changes occurring after that data snapshot may not yet appear in the annual file.
Official New Jersey property researchNew Jersey A-1 Assessment Appeal: Deadlines, Fees and Evidence
The current official Petition of Appeal instructions add practical details that are often omitted from generic property-search pages.
Filing deadline rule
The general rule is that the county board must receive the appeal by April 1 of the tax year, or within 45 days of completion of the bulk mailing of assessment notices, whichever is later. For a qualifying municipality-wide revaluation or reassessment, the general deadline is May 1.

The instructions say the fee accompanies the original petition, is payable to the County Tax Administrator and is non-refundable. Certain petitions contesting denial of specified veteran or senior/disabled deductions do not require the standard filing fee.
Copies and attachments
- File the original petition with the County Board of Taxation.
- Serve a copy on the municipal assessor.
- Serve a copy on the municipal clerk.
- Keep a copy for yourself.
- Include supporting attachments with the assessor’s and municipal clerk’s copies as required.
Comparable-sale evidence
The current instructions permit up to five comparable sales. If they were not submitted with the petition, the comparable information generally must reach the assessor, clerk and county board no later than seven calendar days before the hearing.
- Include block and lot.
- Include sale price.
- Include sale/deed date.
- Use actual comparable sales—not merely neighboring assessments—as evidence of market value.
- Photos, survey and cost information can also be relevant.
North Carolina: Owner, Parcel and Address Search + UC Atlas
Union County North Carolina provides one of the clearest official search workflows of the four jurisdictions.
Search the Property Portal
The county says owners can search the Property Portal using their name, Parcel ID or address. The portal was introduced so owners could review property-record characteristics and communicate corrections to Tax Administration.
Wrong square footage, bedrooms or bathrooms?
The county says property owners can submit correction requests through the Property Portal for details such as property size or bedroom/bathroom counts. After submission, the Tax Administrator’s Office sends confirmation, reviews the request and may contact the owner if more information or an inspection is required.
Use UC Atlas instead of old GoMAPS links
Union County launched UC Atlas in 2025 after the previous GoMAPS system was retired. UC Atlas supports mapping and property lookup, parcel information, zoning and other geographic layers.
2026 appeal status
The ordinary 2026 real-property appeal window closed when the Board of Equalization and Review adjourned on May 6, 2026.
Owners receiving a real-property assessment notice after the Board’s adjournment can have a separate 15-day appeal period from the later notice. Personal-property appeals use different notice-based timing.
Current 2026 forms
The county’s forms page currently lists the 2026 Real Property Valuation Appeal Form, Personal Property Valuation Appeal Form, Improvement Listing Form and multiple 2026 property-tax-relief forms.

Parcel Maps Are for Research; Deeds Are for Recorded Ownership
South Dakota
Beacon provides the assessment/GIS map. For the recorded instrument itself, use Union County’s Register of Deeds.
Oregon
Use county tax maps or ORMAP for map research. Use the County Clerk/Recorder for recorded real-property documents.
New Jersey
Use the state Property Explorer for parcel identification. Use the Union County Clerk’s Online Public Land Records for deeds and other recorded instruments.
North Carolina
Use UC Atlas for map research. The Register of Deeds says its land-record index is name-based; for an address-first ownership search, begin with the Tax Assessor.
New Jersey recorded-document search
The Union County Clerk’s official online land-record index contains records from June 1, 1977 forward and supports searches including name, date range, book/page and instrument number. Older records can require office research.
North Carolina deed-search limitation
The Union County NC Register of Deeds states that its land-record system is name-based. If you know only an address, use the Tax Assessor property search first, obtain the owner/parcel information and then move to recorded land records.

Union County Property Search FAQs
Which Union County assessor property search should I use?
Confirm the state first. Use the Director of Equalization and Beacon for Union County South Dakota, the Assessor / Tax Collector for Oregon, the municipal-assessor and state parcel system for New Jersey, and Union County Tax Administration’s Property Portal for North Carolina.
Can I search Union County property records by address?
Yes. South Dakota explicitly supports Beacon address search, North Carolina supports Property Portal address search, New Jersey Property Explorer supports address-based parcel research, and Oregon provides an official county property-record inquiry system.
Can I search Union County property records by owner name?
It depends on the state. North Carolina officially supports owner-name searches. South Dakota’s county instructions list Address, Parcel ID and Section/Township/Range rather than owner name. In New Jersey, owner information can be affected by municipal record structure, annual-data timing and privacy redactions.
What is the assessor called in Union County South Dakota?
The county assessor function is performed by the Union County Director of Equalization. That office handles assessment matters and directs users to Beacon for assessed values, basic tax information and GIS data.
Can I use South Dakota Beacon to prove my property taxes are paid?
No. The Union County Treasurer specifically says not to use Beacon to confirm taxes paid or determine the amount currently due. Use the Treasurer’s live tax-payment system or contact the office.
When is the Oregon property-value appeal deadline?
For most Oregon value appeals, the petition is filed with the Property Value Appeals Board after the tax statement is received and before December 31, or the next business day when December 31 falls on a weekend or holiday.
Why must I know the municipality for Union County New Jersey?
New Jersey assessments are prepared by local municipal assessors. Knowing the municipality lets you identify the correct assessment jurisdiction and use address, block-and-lot and other parcel information reliably.
How much does a New Jersey property assessment appeal cost?
The current A-1 instructions list valuation-appeal fees from $5 to $150 depending on assessed value, with separate rules for classification and other appeals. Certain specified deduction-denial petitions have no filing fee.
What happened to Union County North Carolina GoMAPS?
Union County replaced GoMAPS with UC Atlas in 2025. Use UC Atlas for current parcel and GIS research and the Property Portal for assessment-record lookup and correction requests.
Is a Union County assessor or GIS map a legal survey?
No. Assessor and GIS parcel maps are research tools. Use recorded deeds, plats and a professional survey when a legal boundary, fence, easement or encroachment decision depends on the exact property line.
State First, Record Second
The safest Union County property lookup starts with the state—not the owner name. Once the jurisdiction is correct, use the parcel/account identifier whenever possible, verify the tax year and move to the responsible office for payment, appeal or deed work.
This prevents the two costliest mistakes on this search intent: relying on a real property record from the wrong Union County and using an assessor/GIS page as if it were a live tax-payment or legal-title system.
