My parents and I just formed an LLC in Maryland. We raise Livestock and crops for Agriculture purposes. I am confused on which way would be better for tax purposes. We obtained a Federial EIN number but told them that there were mulitple members to the LLC because we all signed the Articles of Organization form sent to the Maryland SDAT. However I want to basically know if I should have told the IRS that there is only one owner to the LLC and therefore change the members of the LLC with the Maryland SDAT. If anyone could let me know that would be greatly appreciated... Thanks.
