Bob, that's a great idea.  Create an LLC to invest in partnerships.  Obtain an EIN number for the LLC and you can use the EIN number instead of a SSN.  The LLC can invest in an unlimited number of partnerships, etc.

But regarding you previous reply, what if the Tax Matters Partner steals one or more of the other partner's SSN.  A jury might say, you could have masked their SSN but you chose not.  

I know one person who described a partnership as a future messy divorce. 

So right now I like the LLC/EIN number idea.  I will need to work on that.

Thanks
