Bill Summary · AB 490

Legislative bill overview

AB 490 proposes allowing California taxpayers to deduct car loan interest payments from their gross income when calculating state income taxes. This would create a new deduction similar to existing deductions for mortgage interest or student loan interest. The bill is currently in the Revenue and Taxation Committee where it has had preliminary hearings.

Why is this important

Currently, California residents cannot deduct car loan interest on state taxes, unlike federal tax treatment in some limited circumstances. This proposal would reduce taxable income for vehicle owners, potentially lowering their state tax liability and affecting state revenue. The impact would be most significant for middle and lower-income households that carry auto debt, as higher-income earners typically benefit less from deductions.

Potential points of contention

  • Revenue impact: California's Legislative Analyst's Office would need to estimate significant state revenue loss, which could pressure other tax or spending decisions
  • Equity concerns: The deduction would primarily benefit car owners and debt-holders, potentially favoring suburban/rural residents over urban transit users, and wealthier individuals with larger loans
  • Policy consistency: California already limits certain deductions (like SALT caps); expanding deductions contradicts recent tax policy direction and federal tax law that eliminated personal auto loan interest deductions
