1065 with a K1 for my personal. It's a partnership business with 1 business partner.
The 1065 for a Partnership is due 3/15 unless it goes on extension and the personal 1040 is due 4/15 unless it goes on extension.
And I hope you meant that the partnership has one partner that is a business entity and not that the partnership has only one partner.
