When a U.S. person is involved in a business partnership that is legally established outside the United States, a significant tax reporting requirement is triggered. Form 8865, “Information Return of U.S. Persons With Respect to Certain Foreign Partnerships,” is the complex and detailed form used for this purpose. This is not for casual, small-scale investments; it applies to substantial ownership and control.
The filing requirements are specific and based on your level of ownership and influence. You must file if you are a U.S. person and you meet any of these conditions:
- You control the foreign partnership. This generally means you own more than 50% of the partnership’s capital or profits interest.
- You own at least a 10% interest in a foreign partnership that is controlled by a group of U.S. persons.
- You contributed property to a foreign partnership in exchange for a partnership interest.
- You had certain reportable transactions with a foreign partnership that you control, such as loans or sales of property.
Form 8865 is an information return. This is a critical distinction.
- File Even with No Income: You are legally required to file this form even if the partnership had zero income, operated at a loss, was completely inactive, or was a mere “shell” entity with no operations.
- Severe Penalties for Non-Filing: The penalties for failing to file Form 8865 are among the steepest in the tax code. They start at $10,000 per form, per year, and can increase by an additional $10,000 for each month the failure continues after the IRS sends a notice, with no maximum limit.
2025 Filing Deadlines and Process
- For Individuals: When filed with your personal Form 1040, the deadline for the 2025 tax year is April 15, 2026 (or October 15, 2026, with an extension).
- For Businesses: If the interest is held through an S-Corporation or another partnership, the form is due with that business’s return, typically by March 17, 2026.
- What the Form Does: The form itself does not calculate a tax payment. Its purpose is to provide the IRS with a transparent view of the foreign partnership’s financial activities, your ownership stake, and your share of its income, gains, losses, and deductions. This information then flows through to your personal tax return.
We advised two U.S. entrepreneurs who started a software company with a third partner based in Canada. For legal and operational reasons, they established the company as a Canadian Limited Partnership. Each U.S. partner owned a 33% stake.
Because each owned more than a 10% interest in this foreign partnership, U.S. tax law required each of them to file their own separate and detailed Form 8865 with their personal U.S. tax returns. This involved consolidating the partnership’s Canadian financial statements, converting them from Canadian GAAP to U.S. GAAP, handling currency translation, and reporting their distributive share of the income on multiple schedules. It tripled the complexity of their tax preparation, but it was mandatory to avoid penalties that could have destroyed their business.

FAQs
I own a 15% stake in a small real estate partnership in Spain that had no income or activity this year. Do I still need to file Form 8865?
Yes, very likely. If you are a U.S. person and own a 10% or greater interest in a foreign partnership, you are generally required to file Form 8865, even if the partnership was inactive, generated a loss, or had no operations. The filing requirement is based on your ownership percentage, not the partnership’s income level. Failure to file can result in severe penalties starting at $10,000.
What exactly does it mean to “control” a foreign partnership for filing purposes?
For Form 8865, “control” is specifically defined as owning more than a 50% interest in the partnership’s capital, profits, or voting power. If you are the sole majority owner, you are considered a “controlling partner” and must file under stricter reporting rules, which may require you to attach the partnership’s complete balance sheet and income statement.
If our entire partnership group consists of U.S. persons, do we all have to file separate forms?
Yes, typically. Each U.S. partner who meets a filing threshold (e.g., owns at least a 10% interest or is part of a U.S.-controlled group) must file their own separate Form 8865 with their individual or business tax return. One partner cannot file on behalf of the others. However, a single, detailed “master” Form 8865 may be filed by the controlling partner, with others filing a simplified version referencing it.
How is the 10% ownership threshold calculated? Is it based on capital or profits?
The 10% threshold is measured by your share of the partnership’s capital or profits interest. The IRS looks at the larger of the two. If you have a 12% capital interest but an 8% profits interest, you are considered a 12% owner and must file. The determination is made on any day during the partnership’s tax year.
I contributed my patent to a foreign partnership in exchange for a membership interest. Is this a reportable event?
Absolutely. Contributing property (intellectual property, real estate, equipment, etc.) to a foreign partnership in exchange for an interest is a significant reportable event. You must file Form 8865 and report the contribution, often requiring a disclosure of the property’s fair market value and tax basis. There can also be immediate U.S. tax implications if you contributed appreciated property.
Does filing Form 8865 mean I pay U.S. tax on the partnership’s entire income?
Not on the entire income. You report your distributive share of the partnership’s income, gains, losses, deductions, and credits on Form 8865. These items then “flow through” to your personal tax return (e.g., Schedule E of Form 1040), where you are taxed on your share of the net income, regardless of whether the partnership distributed any cash to you.
