Here is a little secret that some know about but most don't.
The IRS has a file on you and it is called an Individual Master File. In this file is the coding for your tax payer status.
The funny thing about this file is that most employee's of the IRS do not know how to read it. They don't know because everything at the IRS is compartmentalized keeping most at the agency from understanding more than the smallest part of their job.
This IMF must be kept 100% by law Title 5 if I remember correctly. In order to read the file you must refer to a couple of other regs you must refer to but again IRS employee's are not given this training. The master file will show that you are not a tax payer subject to Title 26.
There are people out there who can read the file and from what I have seen so far, I've just started learning, they are very successful.
