    Calculate your OBBBA car loan interest tax deduction for 2025-2028. See how much you can save on auto loan interest with the new above-the-line deduction for US-assembled vehicles.

    How Much Can You Save with the Car Loan Interest Tax Deduction?

    If you bought a US-assembled vehicle in 2025 or later, you may qualify for an above-the-line tax deduction on your car loan interest. Using the OBBBA Auto Loan Savings Calculator, I found that this deduction could save me $500-$1,500 annually, depending on my loan details and tax bracket. Here’s how it works and what you need to know.

    Who Qualifies and How Much Can You Deduct?

    The deduction applies to loans on new or used vehicles assembled in the US, purchased between 2025 and 2028. The interest deduction is capped at $1,500 annually ($1,000 for married filing separately). For example, if you paid $2,000 in interest on your car loan, you can deduct $1,500. If you paid $800, you deduct $800.

    Your savings depend on your tax bracket. If you’re in the 22% bracket and deduct $1,500, you’ll save $330 ($1,500 × 0.22). In the 32% bracket, that same deduction saves $480.

    Real-Life Example: Crunching the Numbers

    Let’s say you bought a $30,000 car in 2025 with a 5-year loan at 6% interest. In the first year, you’d pay about $1,800 in interest. Since the deduction is capped at $1,500, you’d deduct $1,500.

    • If you’re in the 24% tax bracket, your savings would be $360 ($1,500 × 0.24).
    • If you’re in the 12% bracket, your savings would be $180.

    Over the life of the loan, assuming you deduct the max each year, you could save $1,800 in the 24% bracket or $900 in the 12% bracket.

    Tips to Maximize Your Deduction

    1. Check Your Vehicle’s Eligibility: Only US-assembled vehicles qualify. Look for the Vehicle Identification Number (VIN) or check the manufacturer’s details.
    2. Keep Records: Save your loan agreement and interest statements to prove your deduction.
    3. Plan Your Purchase: If you’re considering buying a car, prioritize US-assembled models purchased between 2025 and 2028 to take advantage of this deduction.

    This deduction is a great way to offset the cost of financing a car, but it’s temporary—so act before 2028. Use the OBBBA Auto Loan Savings Calculator to estimate your savings and see if you qualify.
