Who Must File Form 8865

Form 8865 is required for U.S. persons in four categories: Category 1 — U.S. persons who controlled a foreign partnership (owned more than 50% of the profits, losses, or capital interest) at any time during the year; Category 2 — U.S. persons who owned at least 10% of the foreign partnership while the partnership was controlled by U.S. persons; Category 3 — U.S. persons who contributed property to a foreign partnership in exchange for a partnership interest; and Category 4 — U.S. persons who acquired or disposed of an interest that changed their ownership to or from 10% or more.

Frequently Asked Questions

My client owns 15% of a foreign LLC that is treated as a partnership for U.S. tax purposes. Do they need to file Form 8865?
Yes — if the foreign LLC is classified as a partnership for U.S. tax purposes (either by default or by election), and the client owns 10% or more of the LLC, they are a Category 2 filer and must file Form 8865. The form is attached to the client's individual tax return (Form 1040). The client must report their share of the foreign partnership's income, deductions, and credits on Schedule K-1 (Form 8865). Failure to file results in a $10,000 penalty per year, which can be reduced or waived for reasonable cause.
