Deduction for Independent contractor with a W-2. Can I deduct anything?

I am an independent contractor. I do occasional work for an out of state company that gives me a w2. They pay my expenses and in some cases reimburse me for hotels and such. They do take taxes out of what they pay me. Can I deduct anything?  Also, I contacted a tax attorney.  She said that they many be taking credit for services.  Not sure what that means and if it has anything to do with my situation.
