In Episode 154 of the Teaching Tax Flow podcast, hosts Chris Picciurro, CPA, and John Tripolsky rev up a discussion on one of the most surprising new provisions from the One Big Beautiful Bill Act (OB3): a personal tax deduction for qualified automobile loan interest.
Chris and John break down how this above-the-line deduction works, the criteria for qualifying, and the potential pitfalls for taxpayers. From vehicle requirements to phased-out income thresholds, they explain how this law is designed to incentivize specific behaviors and how taxpayers can maximize the benefit.
The episode also includes case studies and examples showing how taxpayers in different income brackets may be affected, emphasizing the importance of marginal tax rate planning to understand the real financial impact.
What You’ll Learn:
• The specifics of the new automobile loan interest deduction under OB3
• Requirements for eligibility (new vehicle, U.S.-assembled, secured loan)
• How phase-outs at $100K (single) and $200K (married filing jointly) affect deductions
• Practical examples of how different taxpayers qualify—or don’t
• Why your marginal tax rate (MTR) is a critical metric for evaluating tax strategies
Key Insights:
This new provision could provide meaningful savings for qualifying taxpayers, but the rules are nuanced. Proper planning ensures you avoid phase-out surprises and maximize deductions where possible.
