Cincinnati Campus Toll-Free Telephone Number
Estate representatives and executors can call Cincinnati Campus at the toll-free number of 1-866.699.4083 to inquire about the examination status of a filed estate tax return, Form 706, during "normal business hours" of 7 am to 7 pm Eastern time. Given the regular processing time frames, however, it is pointless to call until at least 5 or 6 months have passed since the return was filed.
More meaningful is that this toll-free number can be used to contact the person who is actually handling the section 6166 accounting and billing file for an estate at any time during the deferral period. Simply call the toll-free number, listen to the voice prompts, and then ask to speak with the person handling the 6166 billing file for your estate. NOTE: You must have a valid Power of Attorney, Form 2848, authorizing you to represent the estate before the IRS in order to speak with that person, or you must be the executor or administrator of record.
The direct telephone extension of the person handling the 6166 billing file can also be obtained from the annual billing notice sent out by Cincinnati Campus.
