In general, U.S. investors investing in C-corporations on Republic will only need to report income when they realize a gain or loss for tax purposes and no K-1 is due to you. In other words,

When obtaining liquidity such as through selling a position,
When earning interest, or
When receiving and then selling a digital asset (token).
In these cases, the company you invested in (or its 3rd party transfer agent) will provide you with the necessary documents.
