Line 17 on Worksheet for Determining Support

[AndrewA87]

I am trying determine what should included for travel expenses for my son?

Does it include payments I am making on my automobile and camper?  

He also has his own car and I counted his car insurance but nothing he doesn't own like my vehicles and insurance.

[ThomasM125 · Accepted solution]

Since he has his own car, it would not be appropriate to deduct any expenses you have associated with your car or camper. You can deduct the cost of necessities that he needs. The camper would not normally be considered a necessity, as it is likely used for recreation.

Thanks.  I guess the key word I was missing was necessity.
