IDOC or the Institutional Documentation Services is a service that collects family financial documents and distributes them to institutions on behalf of the student. You have to submit them in a specific format within a given deadline. How do you know if you need to submit your tax documents through IDOC? The College Board sends you an email requesting your tax documents be submitted through IDOC. Until this happens, you cannot sign into IDOC. Check out the College Board's IDOC website:
