self-directed Roth IRA w/LLC checkbook control reporting to IRS?

[cooking]

If a person has a self-directed Roth IRA and has invested into an LLC through the IRA (checkbook control), is the only reporting to the IRS for that LLC that which is done by the plan custodian on the yearly asset valuation Form 4598?  Assuming here no UBIT or UFDI, also ignoring the new BOI requirement, which I assume is not a yearly thing.

So if the LLC has, say, a capital gain, it would not be reported separately, if I'm interpreting what I'm reading about this subject correctly?  Trying to make sense of what I'm finding in my research.  Thanks in advance for any help offered.

Your LLC does need to file a BOIR obviously.

Regarding your IRA needing to file a 990-T, that'll possibly occur if your IRA (via the LLC) invests in a partnership or leveraged rental property.

You want to check the IRS instructions for the 990-T.

FWIW, if your IRA needs to file a tax return, I think you've made this too complicated
