SMLLC is a disregarded entity for tax purposes, you'll report it the same as a sole proprietor on Schedule C.

Your state may have additional filing requirements for LLC's.

Only 1 person on the LLC you would file a Schedule C for that LLC.

Check your State to see what other filings have to be done.

A SMLLC can also file as a C corp or as an S corp.

Only 1 person on the LLC you would file a Schedule C for that LLC.

I have (2) Single Member LLCs that are Schedule F.
