What IRS Form 1065 (2025) Is For
IRS Form 1065 (2025) is the U.S. Return of Partnership Income that all domestic partnerships must file each tax year to report income, gains, losses, deductions, and credits to the IRS. Partnerships do not pay federal income tax directly. Instead, profits and losses “pass through” to individual partners, who report them on their own tax returns using Schedule K-1.
Partnerships must accurately report all income, deductions, and other items to comply with applicable tax laws. The return serves as a key document for verifying business revenue, capital gains, and partner allocations. Filing correctly ensures that taxpayers pay the correct amount of tax and avoid penalties or other fees under federal law.
When You’d Use Form 1065 for 2025 (Late or Amended Filing)
You must file or amend IRS Form 1065 (2025) if your partnership missed the March 17, 2025, deadline or received a notice from the IRS, such as CP162B. Late or amended filings are also required when errors are discovered in partner allocations, capital reporting, or when certain entities identify discrepancies in their prior filings.
If you owe penalties, interest, or other fees, the IRS may send a notice by mail outlining your obligations. While partnerships do not receive a tax refund directly, corrected filings may impact each partner’s refund or payment. Partnerships should submit amended returns online through e-file or by mail and retain all related documents for a minimum of three years.
