How to search a St. Tammany Parish property-tax account
Check whether a St. Tammany tax payment posted
The Sheriff’s portal says payments are processed immediately but may take up to 5 business days to appear in the online tax data.
- Keep the transaction ID and receipt.
- Reopen the exact assessment and tax year.
- Do not submit a duplicate just because the website has not updated the same day.
The Assessor’s FAQ explains that a canceled check and the taxpayer’s portion of the bill can serve as a paid receipt. Online or in-person payments provide a receipt at payment.
- Keep the canceled-check image.
- Keep your tax-bill portion.
- Call the Tax Collector if the record still shows unpaid.

When St. Tammany property taxes become delinquent
What changed with St. Tammany delinquent property taxes in 2026?
Louisiana changed the system for 2026. For immovable property, unpaid statutory impositions that remain delinquent can lead to a tax-lien auction rather than the pre-2026 tax-sale-title process.
Louisiana law provides 1% per month or part of a month on delinquent statutory impositions, calculated on a noncompounding basis until payment or issuance of a tax-lien certificate.
The revised law requires delinquency notice and provides for the tax collector to auction the lien after the required notice process.
Search the St. Tammany Parish Assessor property records
Use the Assessor when your question is about the parcel, owner, assessed value, exemptions or property characteristics—not whether the tax payment has posted.
| Search clue | How to use it | Best for |
|---|---|---|
| Assessment number | Enter the number without dashes or punctuation when the system requests assessment number. | Direct record lookup. |
| Owner name | Search the owner/taxpayer name and try a simpler name variation if no result appears. | Finding multiple parcels owned by the same party. |
| Property address | Start with house number and street name; omit suffixes such as Street, Drive or Road. | Finding a home or business parcel. |
| Mailing address / care of | Use when the physical address does not match the owner’s mailing information. | Absentee-owner or mailing-record research. |
| Property description | Use subdivision or legal-description clues when name/address searches are ambiguous. | Complex parcel searches. |
Use the St. Tammany Parish Assessor GIS map
- Zoom to the neighborhood or road.
- Select the likely parcel.
- Compare parcel shape and physical location.
- Use the linked assessment information for owner/value details.
GIS is a property-location and assessment tool. Boundary, title, servitude or survey disputes require recorded land records and professional/legal review rather than a screen measurement.
Check the 2026 assessment before the review deadline
Homestead and special-assessment questions go to the Assessor
A new homeowner who qualifies must apply; the exemption does not automatically follow the owner from the previous home.
The Assessor lists age 65+, an approved Homestead Exemption and income eligibility among the requirements. The maximum listed 2026 AGI is $102,700.
Special-assessment and veteran exemptions can require government ID, disability/VA documentation and tax-return evidence depending on the program.
