Note: The draft you are looking for begins on the next page.

Caution: DRAFT—NOT FOR FILING

This is an early release draft of an IRS tax form, instructions, or publication,
which the IRS is providing for your information. Do not file draft forms. We
incorporate all significant changes to forms posted with this coversheet.
However, unexpected issues occasionally arise, or legislation is passed—in this
case, we will post a new draft of the form to alert users that changes were made
to the previously posted draft. Thus, there are never any changes to the last
posted draft of a form and the final revision of the form. Forms and instructions
are subject to OMB approval before they can be officially released, so we post
drafts of them until they are approved. Drafts of instructions and pubs usually
have some additional changes before their final release. Early release drafts are
at IRS.gov/DraftForms and remain there after the final release is posted at
IRS.gov/LatestForms. Also see IRS.gov/Forms.
Most forms and publications have a page on IRS.gov: IRS.gov/Form1040 for
Form 1040; IRS.gov/Pub501 for Pub. 501; IRS.gov/W4 for Form W-4; and
IRS.gov/ScheduleA for Schedule A (Form 1040), for example, and similarly for
other forms, pubs, and schedules for Form 1040. When typing in a link, type it
into the address bar of your browser, not a Search box on IRS.gov.
If you wish, you can submit comments to the IRS about draft or final forms,
instructions, or pubs at IRS.gov/FormsComments. Include “NTF” followed by the
form or pub number (for example, “NTF1040”, “NTFW4”, “NTF501”, etc.) in the
body of the message to route your message properly. We cannot respond to all
comments due to the high volume we receive and may not be able to consider
many suggestions until the subsequent revision of the product, but we will
review each “NTF” message. If you have comments on reducing paperwork and
respondent (filer) burden, with respect to draft or final forms, please respond to
the relevant information collection through the Federal Register process; for
more info, click here.
