How do auto-loan payments factor into taxes for cars that are solely used by dependent(s)?
I don't see how allowing usage of your vehicle is less support than giving money to buy their own vehicle. If that's the only vehicle your mother has - then you're supporting her. Quantifying that support may be difficult though, but if you are providing her all of her needs - it doesn't matter. If she does have income of her own, I do not think that you can put the actual amount you're paying as part of the calculation towards the 50% rule since she would otherwise have bought a much cheaper car. But if you pass the 50% threshold even without the car payments - then you're fine either way.
