Deductions & credits

Thank you! This was very helpful. 

 

Now I'm stuck on Basis for gain/loss and Basis for AMT gain/loss. Not sure what these mean. 

I am able to do this calculation: 

Price of the vehicle when placed in service: $15K. 

Used 10% for business. 

Total mileage when disposed of = X. 

X times 10% = Y. 

What I do with Y in relation to Basis for gain/loss or Basis for AMT gain/loss, I do not know. 

 

Any suggestions on this?
