How to pay St. Tammany Parish property tax without choosing the wrong account
The Sheriff’s Office is the Tax Collector. The Assessor does not send tax bills and does not collect property payments.
Search by new assessment number
Beginning with the 2022 tax year, the payment system says all properties were assigned new assessment numbers. Use the new number for payment.
Checking / savings account
The online system says there are no fees for payments made from checking or savings accounts.
Debit / credit card
Debit and credit card payments have a 2.5% convenience fee with a $1.00 minimum charge.
1
Open the official Sheriff payment search
Use the Tax Collector system, not the Assessor search, for payments.
▾
Go to the St. Tammany Parish Sheriff online property tax system. Search by assessment number, property address, or name on the tax roll.
2
Confirm the tax year and exact property
Wrong-property payments are painful to correct.
▾
Verify assessment number, owner name, property address, tax year, parish/city tax, exemptions, total due, interest, fees and whether any payment is already posted.
3
Watch delinquent and tax-sale timing
2026 rules shorten collection timing.
▾
The payment system states that payments are processed immediately but may not show for up to 5 business days. It also states that as of July 1, 2026, payments are no longer accepted online, and the Tax Lien Auction is scheduled for July 29, 2026. All payments must be in office before close of tax sale; no postmarks are accepted.
4
Save payment proof and know when a certificate is required
A website balance is not a legal tax certificate.
▾
Save the receipt or confirmation. If you need certification of taxes paid for a sale, refinance or legal requirement, the online payment system says to contact the Tax Collector at 985-809-8217 for a tax research certificate.
How to search St. Tammany Parish assessment records
Use the Assessor search for assessment, property value and exemption information. Use the Sheriff tax system for payment status.
| Need | Use This Official Tool | Useful Search Tip |
|---|---|---|
| Assessment value / ownership | Assessor Assessment Search | Use assessment number, name, address or available search type. |
| Map / physical location | GIS Parcel Viewer | Use for location help, not as a legal survey. |
| Tax payment status | Sheriff Tax Collector system | Use the new assessment number when available. |
| Acts of sale / liens / surveys | Clerk Land Records | Use for recorded documents, not assessed value. |
1
Start with the Assessor Assessment Search
It is free and should not ask for payment information.
▾
Open Assessment Search. The Assessor says checking assessment information on its site is a public service with no charge and it will never ask for credit card information or payment.
2
Use address carefully
Bad formatting causes no-result searches.
▾
The Assessor’s guidance says when searching by property address, do not use suffixes such as street, drive or road for better results.
3
Know which roll year you are viewing
Certified and current rolls may differ.
▾
The Assessor search notes the database defaults to 2025 certified tax roll data. 2026 ownership and assessment-number updates can appear, but 2026 assessed values, tax estimates, exemptions and special assessments are listed in August during the public inspection period.
2026 St. Tammany assessment review and Board of Review deadlines
Do not wait for a November tax bill to dispute assessment value. The Assessor specifically encourages owners to review assessments every August.
| 2026 Review Step | Official Date / Detail | What To Do |
|---|---|---|
| Public exposure / review period | Monday, August 17 through Monday, August 31, 2026 | Check assessment, mailing address, physical address, exemptions and special assessments. |
| Assessment Review deadline | Monday, August 31, 2026 | File with the Assessor by the last day of public inspection. |
| Board of Review appeal deadline | Monday, September 14, 2026 at 4:30 p.m. | Use if a timely Assessment Review was filed and you are not satisfied with response. |
| Storm Review | Can be filed after storm damage | Use for hurricane, flood, tornado or similar damage regardless of normal deadlines. |
What appeal is actually about
An assessment appeal is not a general complaint about tax dollars. It attempts to prove estimated market value is incorrect or inequitable.
Evidence that helps
Incorrect property record items, comparable sales, photos, condition problems, appraisal evidence or inequitable comparable values.
Late filing risk
Assessment Reviews and Appeals received after the legal deadline can forfeit appeal rights and be processed only after timely reviews.
How to estimate St. Tammany Parish property tax
The Assessor links a property tax calculator, but your final tax bill comes from the Sheriff Tax Collector. Estimate for planning only.
Simple Louisiana-style tax estimate
Then multiply taxable assessed value by applicable parish/city millage and add eligible parcel fees, interest or costs if delinquent.
Assessment record example
Assessor tax-roll records can show parish mills, city mills, parish taxes, city taxes, fair market value, assessed value, homestead value, taxable value, freeze type and exemption type.
City taxes may be included
The Assessor FAQ says the Sheriff collects all municipalities with a millage, including Slidell, Mandeville, Covington, Abita Springs, Pearl River and Madisonville.
Millage changes matter
Property taxes can rise when assessed value rises or when taxing authorities keep rates high enough to collect more revenue.
Delinquent tax is different
After timely payment ends, interest and costs can change the total. Always check the Sheriff payment system for current balance.
Homestead, Freeze, Disability, Veteran and First Responder property tax help
The Assessor handles exemptions and special assessments. Payment staff cannot decide if you qualify for assessment relief.
Homestead Exemption
Assessor forms guidance says you need a driver’s license or voter registration showing your current address and a copy of your recorded cash sale or deed.
Freeze applications
To apply for a Freeze, bring proof of age and most recent federal tax returns showing combined Adjusted Gross Income of $102,700 or less. Beginning in 2026, the income requirement adjusts annually with CPI.
Appointment rule
Homestead, Senior, Disability, Veteran Freeze and Special Assessment applications must be made in person at an office location or via Zoom.
Disabled veteran special exemption
The Assessor says veterans with a VA disability rating of 50% or more may be entitled to a Special Exemption in addition to Homestead; a surviving spouse may also be eligible.
Storm Review
If property received storm damage from hurricane, flood, tornado or similar event, the Assessor says Storm Review Applications may be filed regardless of normal deadlines.
Online forms
The Assessor encourages online forms for faster response, including Assessment Review, First Responder, Use Value, Storm Damage and calculator routes.
When you need the Clerk of Court instead of Assessor or Sheriff
Tax records do not replace recorded land records. For deeds, mortgages, liens and surveys, use the Clerk of Court.
| Document / Task | Correct Office | Official Detail |
|---|---|---|
| Acts of sale | Clerk Land Records | Land Records maintains Mortgage and Conveyance records. |
| Mortgages / liens | Clerk Land Records | Public can research and obtain copies of recorded documents. |
| Judgments of possession | Clerk Land Records | Useful for succession and ownership chain questions. |
| Maps and land surveys | Clerk Land Records / surveyor | GIS map is helpful but not a legal survey substitute. |
| Property tax archives | Clerk Land Records | Clerk page states users may view property tax archives. |
