Schedule K-1 Form 1120-S: Simple guide for S corp owners
As an S corporation owner, it is important to understand your tax obligations. One key form you need to be familiar with is Schedule K-1 (Form 1120-S).
This guide will help you navigate the complexities of 1120-S Schedule K-1 to ensure compliance and maximize available deductions and credits.
What is Schedule K-1?
Schedule K-1 is a tax document used to report each shareholder's share of an S corporation's income, deductions, credits, and other financial information.
It is an integral part of Form 1120-S, the annual tax return that S corporations file with the IRS. The form breaks down the corporation's financial activities into portions attributable to each shareholder, allowing them to accurately report their share on their individual tax returns.
Components of Schedule K-1
Part I: Information About the Corporation
This section includes the S corporation's name, address, and Employer Identification Number (EIN). It also shows the type of entity and the IRS filing year.
Part II: Information About the Shareholder
This section collects the shareholder's identifying information, including the shareholder's name, address, and taxpayer identification number (TIN). It also shows the shareholder's percentage ownership for the year.
Part III: Shareholder's Share of Current Year Income, Deductions, Credits, and Other Items
This is the most detailed section where the S corporation reports the shareholder's allocated share of various financial items. Key items include:
- Ordinary business income (loss): The primary income or loss from the corporation's operations.
- Net rental real estate income (loss): Income or loss from real estate rental activities.
- Interest income: Income earned on interest-bearing accounts or investments.
- Dividend income: Income received from stock dividends.
- Capital gains (losses): Gains or losses from the sale of capital assets.
- Deductions, such as Section 179 expensing: Allowable deductions that may reduce taxable income.
Requirements for filing and reporting
For the S corporation
The S corporation must file Form 1120-S annually, along with a completed Schedule K-1 for each shareholder. This form must be filed by the 15th day of the third month following the end of the corporation's tax year (usually March 15 for calendar year filers).
Filing steps for the S corporation:
- Complete Form 1120-S. Gather all necessary financial information for the fiscal year.
- Prepare a Schedule K-1 for each shareholder. Ensure that each shareholder's share of income, deductions, and credits is accurately reported.
- File Form 1120-S and Schedule K-1 with the IRS. File electronically or by mail by the due date.

- Report income and deductions on Form 1040. Transfer the relevant information from Schedule K-1 to your personal tax return.
