I traded in my old car to purchase a new car (as in, latest year, never been owned before) in the middle of last year. I'm filling out my taxes and TurboTax is asking me to fill out the "FMV of like-kind property you received". I assume that FMV stands for "Fair Market Value"
According to this site:
The FMV of the like-kind property received is the price or value of the new vehicle you purchased, before any trade-in allowance.
In looking through my records, I see two numbers for my new car: the MSRP price and the lesser "Price Before Savings" that the dealership was offering. The difference is about two thousand dollars.
Which price is the IRS looking for?
As noted in the comments, I had made a mistake in TurboTax, so I didn't actually need to fill this out. Still, I figure I'll keep this question open for the benefit of others who may be asking it.
