Schedule K-1: What It Is, Who Gets One, and How to File

If you’ve ever been a partner in a business, a shareholder in an S corporation, or a beneficiary of a trust or estate, chances are you’ve encountered a Schedule K-1. For many taxpayers, this form arrives in the mail and immediately raises questions. Here’s everything you need to know.

TL;DR: A Schedule K-1 is a tax form that reports your share of income, deductions, and credits from a pass-through entity. Getting it right matters for your tax return.

What Is a Schedule K-1?

A Schedule K-1 is an IRS tax form used to report a taxpayer’s share of income, deductions, losses, and credits from a pass-through entity. Unlike a traditional corporation (a C-corp) that pays its own taxes, pass-through entities don’t pay federal income tax at the entity level. Instead, profits and losses “pass through” to the individual owners or beneficiaries, who then report that information on their personal tax returns.

Who Receives a Schedule K-1?

You’ll receive a K-1 if you are:

  • A partner in a general or limited partnership
  • A shareholder in an S corporation
  • A beneficiary of a trust or estate
  • A member of certain LLCs taxed as partnerships

Each type of entity files a slightly different version of the form (partnerships use Form 1065, S corporations use Form 1120-S, and trusts and estates use Form 1041) but all produce K-1s for their owners or beneficiaries.

The K-1 contains a detailed breakdown of your allocated share of the entity’s financial activity for the year, including:

  • Ordinary business income or loss
  • Rental income or loss
  • Interest, dividends, and royalties
  • Capital gains and losses
  • Deductions such as Section 179 deductions or charitable contributions
  • Tax credits passed through to you
  • Self-employment earnings, if applicable

The form also includes identifying information for both the entity and the recipient, such as taxpayer identification numbers and ownership percentages.

When Are Schedule K-1s Due?

Partnership and S Corporation K-1s

K-1s from partnerships (Form 1065) and S corporations (Form 1120-S) are generally due by March 15 (in 2026, March 15th falls on a Sunday, so the due date is March 16th), the same deadline as the entity’s tax return. If the entity files for an extension, it gets until September 15, which means your K-1 could arrive late in the year.

Trust and Estate K-1s

K-1s from trusts and estates (Form 1041) follow the April 15 filing deadline, with an extension available through September 30.

Because K-1s can arrive later than standard tax documents like W-2s and 1099s, many K-1 recipients need to file for a personal tax extension.

How Do I File Taxes If I Received a Schedule K-1?

Once you receive your K-1, you’ll need to transfer the information onto your personal Form 1040. The specific schedules you’ll use depend on what’s reported on your K-1:

  • Schedule E is used to report partnership and S corporation income or loss
  • Schedule D handles capital gains and losses
  • Schedule SE covers self-employment tax, if applicable

It’s important to report every item accurately,  misreporting K-1 income is a common audit trigger. If you receive K-1s from multiple entities, the complexity compounds quickly.
