Frequently Asked Questions
Can high earners deduct Macan loan interest?
Only partially — the MAGI phase-out reduces the deduction above the statutory thresholds. Run your real MAGI through the calculator.
Is there a vehicle price limit like the old EV credit?
No price cap — the limiter is the $10,000 interest cap and the MAGI phase-out, not the sticker.
