Add attachments to 1042 forms

Follow these steps to attach 1042-S forms to a 1042 form.

If you are reporting values on line 61 of a 1042 form, you must include the 1042-S forms as attachments that correspond to those values and were previously filed with the IRS.

Attachments added to a 1042 form are automatically included when the form is printed and submitted to the IRS.
Note:

To correct attachments after submitting to the IRS, you must correct the 1042 form and submit it again.

  1. When creating a 1042 form, click Save, then scroll down to line 61 and click Manage 1042-S forms.
  2. Click Add attachment.
  3. Fill out the 1042-S form as it was reported to the IRS. Then click Save.
    The attached 1042-S form is validated with standard 1042-S validations. If it has a validation error, the 1042 form it is attached to can still be saved, printed, and submitted to the IRS.
  4. Optional: Click [Payer ID #] Attachments to return to the Attachments page and add more.
    The Payer ID number Attachments breadcrumb is highlighted.
    Tip:

    Click Form 1042 to return to the 1042 form.
