What is Schedule K-1 (Form 8865)?
Schedule K-1 (Form 8865), Partner's Share of Income, Deductions, Credits, etc., is the Internal Revenue Service (IRS) schedule of Form 8865 that reports one partner's share of a partnership's income, deductions, credits and other items for a tax year.
This edition is for calendar year 2025, or a tax year beginning in 2025 and ending on the date entered at the top. It carries OMB No. 1545-0123 and Cat. No. 28396B. Two boxes at the top let you mark the schedule as Final K-1 or Amended K-1.
The schedule is built in three parts:
- Part I, Information About the Partnership: the partnership's employer identification number (A1), a reference ID number (A2) and the partnership's name and address (B).
- Part II, Information About the Partner: the partner's SSN or TIN (C), the partner's name and address (D1), disregarded entity details if the interest is held through one (D2), the partner's share of profit, loss, capital and deductions (E), the capital account analysis (F) and the net unrecognized section 704(c) gain or loss (G).
- Part III, Partner's Share of Current Year Income, Deductions, Credits, and Other Items: boxes 1 through 21, from ordinary business income (box 1) to foreign taxes paid or accrued (box 21).
Do not confuse this page with other schedules that share the K-1 name: it covers only the schedule printed as Schedule K-1 (Form 8865). Line E refers to the Partner's Instructions for Form 1065, and the form directs you to the Instructions for Form 8865 for its Paperwork Reduction Act Notice and line-by-line guidance.
Who needs to file Schedule K-1 (Form 8865)?
Schedule K-1 (Form 8865) is addressed to a partner: Part II identifies the partner by SSN or TIN, name and address, and Part III reports that partner's share of the partnership's items for the year. The partnership's information goes in Part I. The form itself does not say who must prepare or file it; the Instructions for Form 8865 at www.irs.gov/Form8865 cover that.
Points the form states for specific situations:
- Disregarded entities. Line C says not to use the TIN of a disregarded entity. If the partnership interest is owned through a disregarded entity (DE), line D2 asks for the DE's TIN and name.
- Corrections. Check Amended K-1 when the schedule corrects one already issued, and Final K-1 when it is the last one for the partner.
- Sale or exchange. In line E, a box is checked if a decrease in the partner's share is due to a sale or exchange of the partnership interest.
- Foreign reporting. Box 16 is checked when Schedule K-3 is attached.
The form gives no rules for representatives signing for a partner.
When to file Schedule K-1 (Form 8865)
Schedule K-1 (Form 8865) covers one tax year: calendar year 2025, or a tax year beginning in 2025 and ending on the date written at the top of the form. It has no separate due date printed on it, because it is a schedule of Form 8865 and follows that form's timing. For the deadline and any extension rules, see the Instructions for Form 8865 at www.irs.gov/Form8865. If a schedule already issued needs correcting, mark Amended K-1 at the top; use Final K-1 for the last schedule for that partner.
Documents you need
- Schedule K-3, when you check box 16 ("Schedule K-3 is attached if checked").
- A written explanation of the amount entered on the line for Other increase (decrease) in the Partner's Capital Account Analysis (line F); the form says to attach it.

Common mistakes to avoid
- Entering the TIN of a disregarded entity on line C; the form says not to, and the disregarded entity's TIN and name belong on line D2 when the interest is owned through one.
- Skipping line D2 when the partnership interest is owned through a disregarded entity.
- Checking box 16 without attaching Schedule K-3; the box means Schedule K-3 is attached.
- Entering an amount for Other increase (decrease) in line F without attaching an explanation.
- Leaving both the Final K-1 and Amended K-1 boxes unmarked when the schedule is a last or corrected one.
- Forgetting to check the line E box when the decrease in the partner's share is due to a sale or exchange of the partnership interest.
- Leaving the tax year beginning and ending dates blank when the year is not the 2025 calendar year.
