I'll add to the confusion.
Both my husband and I work for the same company. Both of us are self employed, too. We're classified as independent contractors. Very legal.
We each get a 1099 at tax time. For all that crap that goes along with that, there's some help there. Your husband can claim all his miles to and from work, any clothes, tools, equipment, meals, motels, etc used for work. I think we could write off $0.50 per mile this past year.
There are so many variables, you really do need to call someone who can explain this to you, based on your own situation. Do you have someone do your taxes? Call them. And start keeping odometer readings and receipts now.
