Washington State Vehicle Title Price Error
So I purchased a car a few months back, and I noticed today with the old title, the seller listed the car price at a much lower price than what I had purchased it for (he put $400 when I bought it for $1400). I'm going to be selling this car soon for about $1000. I was wondering if I would need to pay income taxes on this vehicle if I do sell it, considering the listed price on the title was just $400, and based on the records, this sale would be considered a gain, even though it is a loss of $400, but since the actual price I paid isn't listed, it will look like I gained $600. What should I do in this situation?
