Its really hard to tell but I see a few issues to consider, both buisness and tax. From a business perpsective, are you a qualified lender exempt from the Usury laws, which means, not charging interest above 10% per year (current rate)? Second, from your facts, you state that your LLC lent the money to non owner occopied homes, and that you charged interest. If they paid you interest, then you would have been 1099 possibly, or should have been, but in any event, the itnerest income you recevied (if on a cash method), would be reported as interest income on the IRS form 1065, and then you would receive a K-1 for your share of the income on you tax return. You probably need both a business/tax attorney and a CPA to properly document the legal notes, usury compliance, and tax reporting (CPA will file the return)
Mr. Zeppos gave you a marvelous response. You need to hire a competent CPA to advise you. There are hundreds in L.A., if not thousands, who would fit that description. If you need a recommendation, call me. Yes, interest income is taxable income. If you are the only owner of the LLC then the LLC does not have to file a 1065.
