Thank you for your question.  I am new in the trust world and have taken several classes but this is my first run at applying textbook work to real world scenarios.  I really appreciate your help.  Allow me to elaborate...

Uncle dies with an trust in place.  Uncle's trust document establishes a GST Exempt Trust for the benefit of the Uncle's nephew, Bob. Bob has the full control over the GST Exempt Trust and it is for his benefit only and his decedents.  The document doesn't state a "grantor trust" but given he has full control of the assets (what is sold and what is purchased) so in review to of the Grantor Trust Rules, my thinking is that Bob's trust is a grantor trust.  Bob also mentioned several times it is a grantor trust (but I know the client doesn't always know the right terms).

What do you think about the GST Exempt Trust for Bob - report earnings on Bob's 1040? If so, what is the best way to avoid a matching error with the IRS given Bob's trust has it's own EIN and included on Bob's personal 1040 under his SSN.  Are the Preparer Notes sufficient?

Or would you recommend a different course of action for reporting? or other thoughts to consider?
