After filling form SS-8 how long does it take to get a rulling?
The Process A worker or employer can file Form SS-8 and receive a determination from the IRS. When the IRS receives the request, it will begin research and may come back to the firm and worker for further information. At the end of the process (which might take up to six months) the IRS will either (a) issue a determination letter, which is binding on the IRS, or (b) issue an informational letter, which is advisory but not binding.
