Does Louisiana Tax Overtime in 2026?
As of August 2026, Louisiana has not issued official guidance on whether it recognizes the federal OBBBA overtime deduction (IRC §225). Louisiana starts its income tax calculation from federal AGI, which means the deduction may flow through automatically – but the Louisiana Department of Revenue has not confirmed this. Louisiana's 2026 legislative session addressed certain OBBBA provisions, but individual treatment of the overtime deduction remains unconfirmed. Louisiana's flat 3% income tax rate applies to all taxable income.
How Louisiana's Overtime Tax Treatment Works
Louisiana's tax system underwent a major overhaul with Act 11 of the 2024 Third Extraordinary Legislative Session, replacing the prior graduated rate structure (2%, 4%, 6%) with a flat 3% rate effective January 1, 2025. Despite this reform, Louisiana continues to use federal adjusted gross income (AGI) as its starting point for computing state taxable income.
The federal OBBBA overtime deduction (IRC §225) is an above-the-line deduction – it reduces federal AGI before that figure reaches any state return. In states that start from federal AGI, above-the-line deductions generally flow through automatically unless the state enacts a specific addback. This structural feature makes it likely that the overtime deduction would reduce Louisiana taxable income – but "likely" is not "confirmed."
The uncertainty exists because Louisiana's 2026 legislative session addressed certain OBBBA provisions at the corporate level, and the LDR has not published guidance clarifying whether the individual overtime deduction is recognized, added back, or subject to any Louisiana-specific limitations. Until official guidance is issued, Louisiana workers who earn overtime face genuine ambiguity about their state tax treatment.

Worked Examples Comparing Federal and Louisiana Treatment
Example 1: Offshore oil rig worker (single filer, $50,000 income, $8,000 overtime premium)
Qualifying overtime premium: $8,000
Overtime deduction claimed: $8,000 (capped at $12,500)
Estimated federal tax savings: $960.00
Louisiana return:
Louisiana's treatment of the federal overtime deduction is unknown. If Louisiana recognizes the deduction (because it flows through federal AGI), the state savings would be approximately $240 ($8,000 × 3%). If Louisiana decouples, overtime remains fully taxable at the flat 3% rate. No LDR guidance has been issued as of August 2026.
Example 2: Refinery operator (single filer, $78,000 income, $12,500 overtime premium - federal cap reached)
Qualifying overtime premium: $12,500
Overtime deduction claimed: $12,500 (capped at $12,500)
Estimated federal tax savings: $2,750.00
Louisiana return:
Louisiana's treatment is unconfirmed. If the deduction flows through federal AGI to Louisiana, state savings would be approximately $375 ($12,500 × 3%). If Louisiana decouples, the full $12,500 in overtime premium pay remains taxable at 3%. The federal savings of $2,750 apply regardless of Louisiana's decision.
Why Louisiana's Conformity Status Matters for Overtime Workers
Louisiana has a heavy industrial economy with substantial overtime work. The oil and gas sector, petrochemical refining, offshore drilling, and construction industries employ large numbers of hourly workers who regularly earn overtime premium pay. Hurricane season response, turnaround maintenance at refineries, and offshore shift schedules all generate significant overtime hours.
At Louisiana's flat 3% rate, the maximum state-level savings from the overtime deduction would be $375 for a single filer (3% of the $12,500 cap) or $750 for married filing jointly (3% of the $25,000 cap). While modest compared to the federal savings, this still matters for hourly workers.
Louisiana's 2024 tax reform simplified the rate structure but did not address OBBBA conformity. The flat 3% rate means the state-level savings calculation is straightforward – every dollar of deductible overtime saves exactly 3 cents in Louisiana tax.
What to watch for: Louisiana taxpayers should monitor LDR publications for IT-540 instructions for tax year 2026, any Revenue Information Bulletins (RIBs) addressing OBBBA, and any 2027 legislative session activity. If no addback is enacted or announced, the structural default (federal AGI flow-through) may apply – but taxpayers should not rely on this assumption without professional guidance.
