What Is IRS Form K‑1 and Who Needs It?

Form K‑1 is the official document used to report each partner’s or shareholder’s share of income, deductions, credits, and other items from a partnership (Form 1065) or S corporation (Form 1120S). The IRS requires every partner or shareholder to receive a Schedule K‑1 so they can correctly report these amounts on their individual tax returns.

Common Mistakes to Avoid When Completing Form K‑1

• Leaving fields blank: Every required box must be completed; otherwise the IRS may reject the filing.
• Mismatched numbers: Ensure that totals on the Schedule K‑1 match the figures on the partnership’s Form 1065 or S‑corp’s Form 1120S.
• Incorrect tax year: Use the tax year that matches the underlying partnership or S‑corp return.
• Wrong entity type: Choose the correct Schedule K‑1 version (1065 vs. 1120S) for your situation.

Where to Submit Your Completed Schedule K‑1

After filling out the form, attach the PDF to your individual tax return (Form 1040) in the appropriate sections for partnership or S‑corp income. If you’re filing electronically, the PDF can be uploaded directly through most tax‑software platforms.
