Get your taxes done using TurboTax

If you have 2 multi member LLC's then you MUST file a Partnership return form 1065 for EACH LLC as the IRS is expecting both returns.  If you have never completed a form 1065 before I highly suggest you seek professional help for at least this first year to get educated.  Also the Partnership returns are due 3/15/18 unless you put them on extension ... filing late will get you billed for penalties & interest.
