Deductions & credits

Thanks @Anonymous 

 

Would the 50% personal use be taxable - let's say I sold it for $22,000. Would I pay tax on the $2,000 that is above the $20,000 adjusted basis?

 

I worry about the IRS seeing I received $10,000 and not declaring it as income anywhere. I guess I just have to explain I reduced the basis of the car if they audit me?
