Common confusion points
What is the difference between 'Foreign Source' (column f) and 'Sourced by partner' (column g) in Part II?
Column (f) lists income sourced internationally, while column (g) specifies that this income was sourced specifically by a partner.
→ Check which category applies to each line item.
When filling out the Total gross income on line 24 of Part II, what should be combined?
The total gross income is calculated by combining the amounts from lines 1 through 23 of Part II.
→ Verify that all applicable lines (1-23) have values entered in columns A, B, or C.
If the partnership is a withholding foreign partnership, where do you enter its EIN?
The partner's WP-EIN must be entered in the designated spot if the answer to question 'A' on Part I is 'Yes'.
→ Confirm the correct EIN is placed next to the Name of Partnership.
What does it mean for income to be 'Sourced by partner' (column g)?
This indicates that the income listed in column (f) originated from a source attributable directly to a specific partner.
→ Review the partnership agreement or documentation to confirm which income streams are sourced this way.
If Part III applies, what is its primary function?
Part III contains Other Information used specifically for preparing Form 1116 or Form 1118, particularly detailing interest expense apportionment factors (Section 2).
→ Check if the partnership needs to prepare those related forms; if so, Part III is necessary.
