Car loan interest deduction in Texas
The car loan interest deduction is a federal benefit. What it means for your Texas return depends on whether Texas taxes income and how it follows the federal rules.
The federal car loan interest deduction (tax years 2025–2028) applies in Texas the same as anywhere — if your vehicle is new, personal-use, US-assembled, financed with a 2025–2028 loan, and your income is under the phase-out. Because Texas has no broad income tax, there is no separate state question to answer.
No state income tax to worry about
Texas does not levy a broad income tax on wages, so there is no state income tax for the federal deduction to reduce — and nothing extra to file at the state level for this. Your entire benefit is the federal deduction, claimed on your federal return.
