| The monies that you have lent the LLC Partnership could be created as either a Capital Contribution or a Loan to the Partnership. The expenses will of course be reported under the business deductions in the appropriate categories.
The choice to treat is a an additional capital contribution or loan to the partnership will depend on your existing basis in the partnership.
If you sustain a loss and have zero basis in the partnership, I would strongly suggest that you treat the monies invested into the LLC as an additional capital contribution to enable you to provide a basis to deduct the losses.
If you have sufficient basis in the LLC, then it might be prudent to record your monies invested as a loan from the Partner. I would also recommend that you establish a proper loan document specifying an interest rate and repayment terms to comply with the IRS requirements regarding partner loans to a partnerships. |
