What is Form 1065?
Form 1065 (U.S. Return of Partnership Income) Form 1065 is an information return filed by partnerships to report income, deductions, gains, and losses. The partnership itself does not pay tax — instead, income "passes through" to partners who report it on their individual returns. Each partner receives a Schedule K-1 showing their share.

Who Needs to File Form 1065?
Domestic partnerships, multi-member LLCs taxed as partnerships, and certain foreign partnerships with US-source income or US partners.
Non-Resident Relevance
If you are a non-resident entrepreneur with a US LLC or US-source income, Form 1065 may be a critical part of your US tax compliance. Consult with a qualified tax professional to determine if this form applies to your situation.
Filing Deadline
March 15 for calendar-year partnerships (15th day of the 3rd month after fiscal year end). 6-month extension available via Form 7004.
Filing on time is critical. If you need more time, file Form 7004 for an automatic 6-month extension before the original due date. Note that an extension of time to file is not an extension of time to pay.
Penalties for Non-Compliance
Penalty Warning
$220 per partner per month (up to 12 months) for late filing. For example, a 2-partner LLC filed 3 months late would owe $220 × 2 × 3 = $1,320.
The IRS enforces these penalties strictly, especially for information returns related to foreign-owned entities. In many cases, there is no reasonable cause exception, making timely filing essential.
