Does New Mexico Tax Overtime in 2026?
Uncertain \ - New Mexico has not confirmed whether it recognizes the federal OBBBA overtime deduction for 2026. NM enacted 2026 legislation addressing OBBBA provisions, but the TRD has not published guidance confirming individual overtime deduction conformity. NM's general IRC conformity and use of the federal standard deduction suggest the deduction may flow through, but this is not confirmed. The federal deduction still applies on your federal return regardless.
How New Mexico's Overtime Tax Treatment Works
New Mexico's income tax generally conforms to the IRC, and the state uses the federal standard deduction by statutory reference. This structural alignment suggests that OBBBA above-the-line deductions may flow through to reduce NM taxable income.
However, the 2026 NM legislation addressing OBBBA focused on corporate tax provisions. The individual income tax treatment of the overtime deduction (§225) was not explicitly addressed. Until the TRD issues guidance, conformity remains uncertain.
New Mexico uses a Gross Receipts Tax (GRT) instead of traditional sales tax. The GRT does not apply to employee wages and does not interact with the overtime deduction.

Worked Examples Comparing Federal and New Mexico Treatment
Example 1: Oil field worker (single filer, $55,000 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
New Mexico return:
As of September 2026, New Mexico has not confirmed whether the OBBBA overtime deduction applies at the state level. If NM conforms: the $8,000 deduction would reduce NM taxable income, saving approximately $392 (at the 4.9% marginal rate). If NM does not conform: the full $8,000 in overtime premium remains subject to NM income tax. The federal deduction still saves $960 regardless.
Example 2: Construction worker (single filer, $80,000 income, $12,500 overtime premium - federal cap)
Qualifying overtime premium: $12,500
Overtime deduction claimed: $12,500 (capped at $12,500)
Estimated federal tax savings: $2,750.00
New Mexico return:
If NM conforms: the $12,500 deduction reduces NM taxable income, saving approximately $613 (at the 4.9% rate). If NM does not conform: the full $12,500 remains taxable at NM rates. New Mexico enacted 2026 legislation addressing OBBBA provisions, but the individual overtime deduction treatment has not been confirmed by the NM Taxation and Revenue Department.
New Mexico’s Tax Structure and Overtime Workers
New Mexico uses six graduated brackets with rates from 1.5% to 5.9%. Most overtime workers fall in the 4.7% or 4.9% brackets. The potential state savings from conformity - up to $613 on the maximum $12,500 deduction - is meaningful.
Key industries: Oil and gas extraction (Permian Basin), national laboratories (Los Alamos, Sandia), construction, and tourism/hospitality. Workers in these sectors frequently earn overtime and would benefit from conformity.
Gross Receipts Tax note: NM uses a GRT instead of sales tax. The GRT is a business tax and does not apply to employee wages or interact with the overtime deduction.
