In May 2026, IRS leadership highlighted provisions of the One Big Beautiful Bill Act (OBBBA), enacted in 2025, that introduce new above-the-line deductions available for the 2026 federal tax year (and tax years 2025–2028). These deductions address senior taxpayers, qualified overtime compensation, and interest on certain car loans. The provisions are claimed on the new Schedule 1-A and may be taken whether or not the taxpayer itemizes deductions. California does not conform to these OBBBA provisions; taxpayers must make appropriate adjustments on their state returns. This publication reflects tax law and regulations applicable as of May 2026 and is subject to change without notice.
This article examines the enhanced senior deduction, the overtime pay deduction, and the qualified car loan interest deduction under the OBBBA for 2026, including eligibility, phase-out rules, documentation requirements, and federal versus California treatment.
Enhanced Senior Deduction Under OBBBA
Taxpayers who attain age 65 by the end of the 2026 tax year may claim an additional $6,000 deduction per qualifying senior ($12,000 if both spouses qualify on a joint return). This amount is taken in addition to the regular senior standard deduction amount.
The deduction begins to phase out when modified adjusted gross income (MAGI) reaches $75,000 for single filers or $150,000 for married filing jointly. It is completely phased out at $175,000 and $250,000, respectively.
Overtime Pay Deduction Under OBBBA
The premium portion of qualified overtime pay (as defined under the Fair Labor Standards Act) is eligible for a deduction of up to $12,500 for single filers and up to $25,000 for married filing jointly. This deduction phases out for MAGI above $150,000 for single filers and above $300,000 for married filing jointly. Proper reporting on Form W-2 is required to substantiate eligibility.
Qualified Car Loan Interest Deduction Under OBBBA
Taxpayers may deduct up to $10,000 of interest paid during 2026 on a loan for a new qualified personal-use passenger vehicle assembled in the United States and purchased after December 31, 2024. The vehicle must meet applicable gross vehicle weight rating and use requirements; the VIN must be reported. The deduction phases out for MAGI exceeding $100,000 for single filers and $200,000 for married filing jointly.
Taxpayers must maintain appropriate documentation, including proof of age for the senior deduction, detailed W-2 information showing overtime premium pay, and loan statements that include the vehicle identification number (VIN) for the car loan interest deduction. Taxpayers who filed prior-year returns before full guidance was issued may file amended returns to claim these deductions, subject to applicable statute of limitations and filing deadlines.
