Just a quick update on what I found in case anyone else is looking. I was able to successfully get TAXMODA mailed to me (faxing and e-service mailbox weren’t options). You must request this information over the phone. If you get push back you can direct the agent to IRM 126.96.36.199.9.5 and IRM 188.8.131.52.4. If they still refuse, ask for a manager.
