| Instalment | Due | Notes |
|---|---|---|
| Annual bill | January 1, 2027 | Ad valorem taxes are delinquent after December 31; some parishes accept partial prepayments before then. |
Louisiana property tax is billed and collected county by county, so the collector — not the state — issues the bill. The December 31 delinquency date is uniform, but parishes run their own notice, prepayment and installment practices.
