I ended up calling the Practitioner hotline, twice, and faxed 2848, twice, to get the answers I needed. Only took about 90 minutes total... First agent stated that client had no CP2000 so no worries. Called state back, challenged how they could have received a CP2000. Was told they had to have some documentation. Soooo, back to hotline, again. Second agent went deeper and discovered CP2000 resolved while first agent simply did not see one 'active.' So I have dutifully chastised client by email for not having provided this information last June when he paid the additional tax to IRS. Grrrr, yes I am charging for this although I normally wouldn't. Second agent sent wage transcript as well as account transcript for which I would have asked first agent had she not insisted there was no outstanding issue currently. Technically correct but not the whole story.
