No you cannot use a passport. The IRS does not require you to enter a drivers license in order to e-file; it just adds an extra layer of security. A few states are pretty picky about the requirement for a driver's license or state ID and will not let you e-file the state without it. He can skip the license part; if the state will not allow e-filing he can print and mail the state.
