IRS Links

Instead of OSHC, the documents are at "libraries"

You need to setup an AARP account to access the Portal. See your LC for details. From the Portal you have access to "libraries".

Portal login. From the Portal's main page click on the "Libraries" tab at the top.
Rather than trying to guess which library they put stuff in, use the search box in the upper left
You can find the Scope Manual, modifiations to Pub 4012, and other stuff that way
