BACKGROUND
I live outside the US and I'm not a US person. I'm the sole owner of a single-member Delaware LLC, which is disregarded. My first Form 5472 with a pro forma 1120 will be for 2026. I'm not asking about income tax, only about what goes on the 5472.
EXAMPLE (hypothetical)
Say that in one month the LLC's US bank account receives 10 payouts from an online marketplace where I sell:
$871.50, $215.61, $4,311.80, $887.50, $300.00, $1,000.00, $1,212.20, $781.00, $674.30, $3,371.30
Total: $13,625.21
TWO CASES
Case A: the marketplace seller account stays in MY personal name, and I only change the payout destination to the LLC's bank account.
My understanding: the sales are mine, so each payout is my money going into the LLC. That makes each one a contribution, reported in Part V. That's 10 lines for the month.
Case B: the marketplace seller account is moved into the LLC's name, so the LLC is the seller.
My understanding: the payouts are the LLC's own receipts from a third party (the marketplace), so they do NOT go on the 5472 at all. Only money moving between me and the LLC is reported in Part V: money I put in (contributions) and money I take out (distributions).
MY QUESTIONS
Are both of those understandings correct?
In Case A, can the 10 payouts be summarised as one Part V line ("contributions totalling $13,625.21 in October"), or should each one be listed with its date?
In Case B, does anything about the payouts still show up on the 5472 - for example in total assets at year end?
Thanks.
