Common confusion points
Ownership % vs. profit‑sharing %
Percentages can differ under partnership agreement
→ Verify both numbers in the partnership agreement
Foreign partnership vs. foreign corporation
Misclassifying triggers the wrong form
→ Check entity’s IRS classification
Contribution vs. acquisition
Different filing thresholds apply
→ Review the specific trigger in the instructions
Multiple partnerships in one year
Each partnership needs its own Form 8865
→ Do not combine data on a single form
Extension filing
Some filers think the extension only applies to the main return
→ Extension also extends Form 8865 deadline
