Exemptions & appeals
View exemption application (opens in a new tab)Senior relief
2026 Senior Freeze: owner age 65+ with homestead exemption and maximum adjusted gross income of $102,700; assessed value may be frozen, but millage and total taxes may still change. Disability and veteran disability freezes also exist.
Valuation limits
No general annual assessment cap was verified; St. Tammany's official FAQ describes Louisiana reappraisal-year phase-in of additional residential homestead tax liability when assessed value increases by more than 50%, over four years. Special assessment freezes are separate and do not freeze millage.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
