I filed the Form 1065 but did not include the K-1's with it.

Do you re-file all documents or just send in the K-1's

#1; you should mail the Form 1065 with all the Sch K-1’s to the IRS. The Sch K-1's are considered part of the partnership return. Also, you should give to each partner a copy of their Sch K-1’s that were issued to them. Ignoring the k-1s will result in a CP2000 adding it in anyway in about a year plus penalties and interest.


#2; I guess you may just send those sch k1s to IRS

Note;Sch K-1 are distributed to the partners. The partners use the information on the K-1 to prepare their personal returns but do not attach copies to their individual returns; they keep them for their records. Partner allocations are reported to the IRS on Sch K which is part of the Form 1065 partnership return.
