I got a W2 as a per diem worker. Barely any federal taxes deducted. No state taxes deducted. Can I deduct expenses from the job like commuting costs and parking fees?

COMMUTING EXPENSES

The expenses of commuting to and from work (or to and from school) such as gas, tolls, bus fare, train fare, taxis, Uber rides, parking, etc. are not deductible on your Federal return.  Sorry.
