Tax treatment of non-US partnership

Hi, hope everyone is doing well.

As part of my employment, I have been required to co-invest into a non-US partnership as a limited partner. My share is less than 1%, with no voting rights or any form of control. The vehicle seems to be treated as a corporation for US tax purposes.

Over the past few years I have invested approx $20k in total of which $5k has been returned through a mix of return of capital, interest income, dividends and capital gains from the underlying investments.

So my question is, where do these streams of income go on the return?

I will most likely renounce early next year, so I don’t need to plan far ahead for the future. Just keen to get this filed in a way that minimises risk and headaches.

Forms that come to mind are 926, 8621, 8938 and and FBAR. Assuming the entity has not elected to be disregarded, because it's classified as a corporation it's a PFIC so you'd be filing an 8621 each year and might have a deemed disposition with some possible PFIC tax as at renouncing. You'll want check though that is not made a check the box election.
