Car loan interest deduction in Alaska

The car loan interest deduction is a federal benefit. What it means for your Alaska return depends on whether Alaska taxes income and how it follows the federal rules.

Alaska has no broad state income tax, so there is no state conformity question — the federal deduction is your entire benefit.
The short answer

The federal car loan interest deduction (tax years 2025–2028) applies in Alaska 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 Alaska has no broad income tax, there is no separate state question to answer.

ℹ️ Alaska has no personal income tax and no statewide sales tax, so there is no state income tax for the federal deduction to interact with.

No state income tax to worry about

Alaska 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.
