St. Tammany Parish Property Records
Search by Address, Parcel, Assessment, Tax Bill and GIS Map
St. Tammany assessor property search starts with the official St. Tammany Parish Assessor assessment search and GIS parcel viewer. This guide shows you how to find property records by address or parcel, avoid bad search formatting, check assessed value, confirm owner/taxpayer clues, open the GIS parcel map, route tax bill questions to the Sheriff’s Tax Collector, and use the Clerk of Court for land records such as acts of sale, mortgages, liens, maps and surveys.
Use the official St. Tammany Parish Assessor assessment search at https://arist.stassessor.org/aristpwa/Search. If you want a map-based lookup, use the GIS parcel viewer at https://atlas.geoportalmaps.com/st_tammany. For property tax bill payment or payment status, use the St. Tammany Parish Sheriff’s Office Tax Collector system. For deeds, acts of sale, mortgages, liens, maps and land surveys, use the St. Tammany Parish Clerk of Court Land Records Department.
What Should You Click First for a St. Tammany Assessor Property Search?
The fastest route depends on what you already have. St. Tammany Parish uses separate official offices for assessment, tax payment and land records. Do not force every question into the Assessor website. Use the correct path below.
I have a street address
Use the Assessor’s assessment search first. When searching by property address, the Assessor warns users not to use address suffixes such as “Street,” “Drive” or “Road” for better results.
Open official assessment searchI need the parcel on a map
Use the GIS parcel viewer when an address is confusing, when the property is vacant land, or when you need visual parcel-location help.
Open GIS parcel viewerI need tax bill or payment status
Use the Sheriff’s Tax Collector system. The Assessor does not send property tax bills and does not collect property tax payments.
Open tax bill searchI need deed, sale or mortgage records
Use the Clerk of Court Land Records Department for acts of sale, mortgages, judgments of possession, cancellations, liens, maps and land surveys.
Open land records pageI disagree with assessed value
Check your assessment during the public inspection period, file an assessment review with the Assessor on time, then appeal to the Board of Review only if you first filed a timely review.
Open check assessment pageI need homestead exemption
Use the Assessor’s forms and appointments route. St. Tammany says homestead, senior, disability or veteran freeze applications must be made in person or by Zoom.
Open forms and resourcesSt. Tammany Parish Assessor Property Search by Address — Micro Step-by-Step Guide
If you have a St. Tammany Parish street address, the official assessment search is the first stop. The key is to search the way the parish system expects, not the way Google Maps or a real estate website formats the address.
Open the official Assessment Search
Go to the St. Tammany Parish Assessor assessment search at https://arist.stassessor.org/aristpwa/Search. If you land on the Assessor website first, use the “Check Your Assessment” route and agree to the terms before choosing the assessment text search or GIS parcel viewer.
Search the address without suffix words
The Assessor specifically advises that when searching by property address, you should not use suffixes such as “street,” “drive” or “road.” Search the house number and street name first. If the exact result fails, remove more formatting and search only the strongest street-name clue.
Watch for city-name confusion
St. Tammany Parish includes areas such as Covington, Slidell, Mandeville, Madisonville, Abita Springs, Lacombe, Pearl River and Folsom. The Assessor record is parish-level, so a city mailing name does not always solve the assessment search. Start with the property address and parcel clues.
Open the matching property result
Review the assessment record carefully. You are looking for the owner/taxpayer clue, assessment number or parcel details, property location, land and building value, homestead/exemption indicators where shown, and any link or map reference that helps confirm you selected the correct parcel.
Use the GIS Parcel Viewer when the address is not enough
If the address search does not work, use the GIS parcel viewer at https://atlas.geoportalmaps.com/st_tammany. This is especially useful for vacant land, new subdivisions, rural addresses, boundary questions and properties with mailing addresses that do not match the physical parcel perfectly.
High-success address tip: Search less, not more. If “123 Oak Drive” fails, try “123 Oak” or just “Oak.” Do not add “LA,” “St. Tammany,” subdivision name, ZIP code or suffix words on the first search. Parish assessment systems often store address fields differently from real estate listing sites.
How to Search St. Tammany Parish Property Records by Owner Name
Owner-name search can be useful, but it is not always clean. In Louisiana parish records, names can appear as legal owners, trusts, successions, LLCs, married names, abbreviations or prior owners until records update. For serious ownership history, do not stop at the assessment screen.
Best route when you know the address
Search the property address in the Assessor system first. Then use the assessment number, parcel reference or owner/taxpayer clue from the record to move into tax payment, GIS or land record research.
Best route when you know only a person or LLC
Try the Assessor assessment search for name clues, but use the Clerk of Court Land Records Department for deeper ownership history. Land Records maintains Mortgage and Conveyance records, including acts of sale, mortgages, judgments of possession, liens, maps and land surveys.
Why a name may not match
A home may be under a trust, estate, succession, company, spouse, previous owner or recorded legal name. The Assessor’s public site also notes that its new Arist assessment system changed certain process timing, including ownership reflection on the tax roll and tax bills with stated exceptions.
When to use Clerk Connect
For subscription-style online land record searching, Clerk Connect may be relevant because it provides civil, criminal and land record inquiry tools for participating Louisiana clerks. Use the St. Tammany Clerk page first to confirm access, fees and current options.
Do not confuse assessment owner clues with title proof: An Assessor record helps identify assessment and tax information. It is not a title opinion. If you need legal ownership, chain of title, mortgage release, judgment or sale document proof, use Clerk land records and a qualified title professional or attorney.
St. Tammany Parish Parcel and Assessment Search — Number, Legal Description and Map Clues
If you already have an assessment number, parcel reference, legal description, subdivision lot number or map location, use that clue before trying a broad owner-name search. Exact identifiers reduce false matches and help you move between Assessor, Sheriff Tax Collector and Clerk records.
Where to find your St. Tammany parcel or assessment clues
Assessment search result
Search by address first, then save the assessment or parcel identifiers shown.
Tax bill
The Sheriff Tax Collector tax bill/payment system may show account and property clues useful for future lookup.
Act of sale
Clerk land records may include legal description, subdivision, lot and conveyance details.
GIS map
Use the parcel viewer to confirm location when the address is vague or newly developed.
Mortgage papers
Lender and title documents often include legal description and tax assessment references.
Subdivision records
Lot, square and subdivision names may help when addresses are incomplete.
Micro-level search rule: If you have a parish assessment number or parcel clue, use it before a person name. If you have only an address, search without suffix words. If you have only a map location, use the GIS viewer. If you have only an ownership-history question, use Clerk land records.
What Shows in a St. Tammany Parish Property Record
A St. Tammany Parish property lookup can lead you to several different record types. The Assessor record is mainly for assessment information. Tax billing comes through the Sheriff’s Tax Collector. Land ownership documents come through the Clerk of Court.
Owner / taxpayer clue
Name information as reflected in the assessment system, subject to timing and legal-name differences.
Property location
Physical address or location information used for assessment and mapping.
Assessment value
Assessment details used in the parish property tax process.
Homestead clue
Possible exemption indicators or related eligibility questions to verify with the Assessor.
GIS map connection
Parcel location, spatial context and boundary reference through the GIS viewer.
Tax payment path
Links or routing to the Sheriff’s Office tax payment and payment status system.
Land record path
Acts of sale, mortgages, liens, property settlements, maps and surveys through Clerk records.
Review / appeal path
Assessment review and Board of Review deadlines during the public inspection process.
Do not treat the parcel viewer as a legal survey: GIS maps help residents and agencies access parcel information, but map lines are not the same as a recorded survey or title boundary opinion. For boundary, easement, fence, servitude or subdivision disputes, review Clerk land records and use a licensed surveyor or legal professional.
St. Tammany Parish Property Tax Records — Bill Search, Payment Status and Tax Collector
The Assessor determines assessed value. The Assessor’s Office does not send property tax bills and does not collect property payments. In St. Tammany Parish, tax bill/payment questions route to the St. Tammany Parish Sheriff’s Office Tax Collector.
Assessment questions
Contact the Assessor when you need help with assessed value, property characteristics, homestead exemption, special assessment level, GIS parcel information or assessment review.
Tax payment questions
Contact the Sheriff’s Tax Collector for tax bill search, payment status, tax research certificates, delinquent amounts and property tax payment issues. Tax Collector phone: 985-809-8217.
Online tax payment
The St. Tammany Parish Sheriff’s Office provides online services for taxpayers, including property tax payment and related secure payment options.
Tax research certificate
If you need certification of taxes paid for a sale, refinance or legal requirement, the online tax system routes users to contact the Tax Collector for a tax research certificate.
Need to check a tax payment? Use the St. Tammany Parish Sheriff’s Office property tax search/payment system, not the Assessor office.
Open Tax Bill SearchDo not wait for a paper bill: If you bought, inherited or refinanced property, check the Sheriff tax system and your mortgage company directly. The Assessor handles value and exemptions; tax payment status is a Tax Collector issue.
St. Tammany Parish GIS Parcel Viewer — Map Search for Parcels, Location and Assessment Clues
Use the GIS parcel viewer when text search is not enough. The St. Tammany Assessor describes GIS mapping as a public resource to help taxing bodies and residents access parcel information and tax assessments. The parcel viewer is especially useful for property location questions and map-based search.
Best for vacant land
If the property has no clear street address, search visually in the GIS viewer and compare nearby roads, subdivision boundaries and parcel shapes.
Best for new subdivisions
New lots may be easier to identify by subdivision, location or map view before address records fully match common search formatting.
Best for city/parish confusion
St. Tammany properties can use city mailing names while assessment and tax records remain parish-level. The map can help confirm the correct jurisdiction and parcel context.
Know the legal limit
GIS is a research tool, not a survey. Do not use the map alone to build a fence, settle a servitude issue or prove legal boundaries.
Map search route: If text search fails, open the official GIS parcel viewer and locate the parcel by physical location.
Open GIS ViewerSt. Tammany Parish Assessment Review and Appeal — Public Inspection, Review and Board of Review
If your assessed value looks wrong, do not wait until tax payment time. St. Tammany’s Assessor page explains that assessment review is tied to the Public Inspection of the Tax Roll period, and a Board of Review appeal requires a timely Assessment Review application with the Assessor first.
Check your assessment online during the review window
The Assessor states that the tax roll may be available online before or during the public inspection period. Check your assessment as soon as the roll is available instead of waiting until tax bills arrive.
Look for factual errors first
Check property location, structure type, square footage, land size, condition, homestead/exemption status and ownership clues. Factual errors are easier to discuss than general complaints about taxes.
File an Assessment Review on time
If the value appears incorrect, use the Assessor’s Assessment Review process within the official deadline. St. Tammany’s 2025 notice stated the legal deadline was the last day of Public Inspection of the Tax Roll period.
Appeal to Board of Review only after timely review
The Assessor page states that a taxpayer must first file a timely Assessment Review application with the Assessor before filing an appeal with the Parish Board of Review.
Use evidence, not emotion
Prepare comparable sales, appraisal evidence, incorrect property data, photos, repair/condition proof and documentation. A tax-rate complaint is not the same as an assessment-value appeal.
Review deadline warning: Dates change by tax year. Always check the current “Check Your Assessment” page before assuming the review or appeal deadline.
Check Assessment PageSt. Tammany Homestead Exemption, Senior Freeze, Disability Freeze and Veteran Benefits
Louisiana homestead exemption and special assessment rules are a major reason people search the St. Tammany Assessor site. The Assessor’s forms page says applications for Homestead Exemption, Senior, Disability or Veteran Freeze or Special Assessment must be made in person at an office location or by Zoom.
Homestead exemption
You may qualify if the property is your primary residence and you do not have another homestead exemption filed elsewhere. The Assessor FAQ says you need identification such as a driver’s license or voter registration card showing the new address.
Apply soon after purchase and occupancy
The Assessor advises new homeowners to apply for homestead exemption as soon as they purchase and occupy the home. If you move primary residence, notify the Assessor.
Senior, disability and veteran freeze
Special Assessment Level or freeze programs have eligibility rules and may require income or disability documentation. Contact the Assessor for the current requirement before assuming you qualify.
How to apply
The Assessor lists Appointments@STPAO.org for details, plus in-person office visits and Zoom appointment options. Bring identification, ownership documentation and residency proof.
Do not use old exemption advice blindly: forms, income thresholds and documentation rules can change. Use the official St. Tammany Assessor forms page.
Open Forms PageSt. Tammany Assessor vs Sheriff Tax Collector vs Clerk of Court — Which Office Handles Your Property Question?
A lot of property-search frustration comes from calling the wrong office. In St. Tammany Parish, assessment, tax collection and land records are handled separately.
St. Tammany Parish Assessor
Use the Assessor for assessed value, property characteristics, assessment search, GIS parcel help, homestead exemption, freeze programs, public inspection and assessment review. Covington phone: 985-809-8180. Slidell phone: 985-646-1990.
St. Tammany Parish Sheriff Tax Collector
Use the Sheriff’s Office Tax Collector for property tax bills, payment status, tax payment, delinquent tax questions and tax research certificates. Phone: 985-809-8217. Email: propertytax@stpso.com.
St. Tammany Clerk of Court Land Records
Use the Clerk for Mortgage and Conveyance records such as acts of sale, mortgages, judgments of possession, cancellations, property settlements, liens, maps, land surveys and property tax archives.
Board of Review / Louisiana Tax Commission path
Use the review and appeal path when the value is wrong. Start with a timely Assessment Review at the Assessor level before attempting Board of Review steps.
Common Problems When Searching St. Tammany Parish Property Records
If the official search is not showing what you expect, the problem is usually formatting, wrong office, record timing, city/parish confusion or a deed/assessment update gap. Fix the search before assuming the record does not exist.
No address result appears
Remove suffixes such as Street, Drive, Road, Lane, Avenue and Court. Try only the street name and house number. Then use the GIS parcel viewer if the text search still fails.
Owner name looks outdated
Recent sales, successions, trusts and LLC ownership can affect timing and name format. Confirm ownership history through Clerk land records, not only the assessment screen.
Tax bill does not match assessed value
Assessment value is not the same as final tax owed. Millages, exemptions, municipal taxes, fees, payment status and delinquency affect the tax bill. Use the Sheriff’s Tax Collector for tax payment issues.
GIS boundary looks wrong
Use GIS as a research layer only. Review Clerk land records, recorded surveys and professional survey work for legal boundaries, servitudes and fence disputes.
You found a paid property website first
Back out and use official St. Tammany Assessor, Sheriff and Clerk links first. Most basic assessment, map and tax-payment routing can be done through official parish systems.
