Common confusion points

Ownership % vs. profit‑sharing %

Partnerships may allocate profit differently from ownership

→ Verify allocation method in partnership agreement

Foreign tax credit vs. foreign tax paid

Credits may be limited by U.S. tax liability

→ Cross‑check with Form 1116 calculations

Domestic vs. foreign partnership

Mistaking a U.S. partnership for foreign triggers unnecessary filing

→ Confirm partnership’s place of organization

Extension filing vs. original deadline

Extensions apply to Form 8865, not automatically to Schedule K‑1

→ File Form 8865 extension before original due date

Electronic vs. paper filing

Some software only supports PDF upload, not separate K‑1 attachment

→ Follow IRS e‑file guidelines for multipart submissions
