I have a client who has a son that spent the summer selling alarm systems (or pesticide or something like that) and has a quite large 1099-NEC.  Is there anyone in the community that has prepared returns with this scenario?  What kind of expenses would we consider eligible?  The employer provided room and board and food while they are gone.  They would get dropped off in neighborhoods and canvas all day and return at night.  Made decent money.  Now the tax man cometh.  Any tips?

Thanks all.
