<p>Do most people FAX in their tax returns to USC? I keep seeing something about the Document Management System where it's done online. My daughter still has to log in so we can see what this is about. If done online, are the tax returns put on a pdf. file? My husband is in charge of this. He's going through IDOCS for another school my daughter is applying to. Anyway, do you find that FAXING the tax returns are the preferred method? I always worry about faxes sitting around and not getting to their designated destination. :)</p>
