Under the OBBBA, taxpayers purchasing new, U.S.-assembled vehicles can deduct up to $10,000 in car loan interest annually from 2025 through 2028. This new provision encourages both smarter financial planning and stronger domestic vehicle production.

The One Big Beautiful Bill Act (OBBBA) permanently sets the mortgage interest deduction limit at $750,000 and expands the deduction to include qualified mortgage insurance. Understanding these changes can help homeowners make smarter tax planning decisions.
