Can family attribution make me a Category 1 filer?

Yes. Ownership by your spouse, children, grandchildren, and parents may be attributed to you under constructive ownership rules, potentially pushing your total above 50%.

What forms do Category 1 filers need to complete?

Category 1 filers must complete the most schedules on Form 8865, including financial statements, balance sheets, and detailed reporting of partnership transactions and allocations.

Category 1: Controlling Interest in Foreign Partnership

Category 1 filers are U.S. persons who control a foreign partnership — meaning they own more than 50% of the capital, profits, losses, or deductions, either directly, indirectly, or through constructive ownership. Category 1 filers face the most comprehensive reporting requirements, essentially reporting nearly the full financials of the partnership.

Constructive Ownership Rules

You cannot avoid Category 1 filing through creative ownership structures. The IRS applies constructive ownership and attribution rules, meaning ownership by your spouse, family members, or entities you control may be attributed to you. For example, if you own 30% directly and your spouse owns 25%, the combined 55% may make you a Category 1 filer.

Similarly, if you own shares in a corporation that owns an interest in a foreign partnership, that interest may be attributed to you through the corporation.
