I formed former an LLC for an odd reason

[Sean Kuhn]

My main goal with the LLC is keeping commercial loans and debt off my personal credit report. With that in mind do I have to file any taxes if the LLC did not produce income? What if I started buying properties in the LLC and those properties produce income, would I have to report taxes through the LLC or could I still file it by myself? Also do you know if I have to disclose my LLC holdings to any creditors or mortgage companies if I'm applying personally? For example if I hold 15 LLC properties do I have to disclose this if I'm applying for a primary residence with a conventional lender? Is that illegal or immoral? Thank you Sean
