Find a K-1 form by typing "K-1" plus the tax year in the search box near the top of the main page in the Form and Pubs section on IRS.gov. Most tax forms for the current and prior tax years, including form K-1, are available for download free of charge on this website, states the Internal Revenue Service.
Searching for "K-1" on IRS.gov yields a link to the K-1 form and a link to instructions on how to complete the form. The form and instructions are in PDF format. You can complete the form using Adobe Acrobat or other PDF programs before printing it, notes the IRS. There are no computation, validation or verification features embedded in the form, so you should accurately compute all figures before completing the form and be sure to make all the required entries.
The K-1 is a reporting form, so individuals do not complete the form themselves. Partnerships and S Corporations pass income and deductions on to partners or shareholders at the end of each tax year using form K-1, states H&R Block. A partner or shareholder who is issued a K-1 form uses it when completing his tax return and includes a copy of the form when he mails his return to the IRS.
