If you have an interest in an OS corp, there is a requirement to file with the IRS and notify of this interest. (Again.. there are exclusions, but you need to check with a tax lawyer on this). The fact that there are filings needed means eg that privacy privileges of that OS corp will not exist and, to a degree diminishes the benefit of the OS corp.
