Tools
Any payer, such as businesses, educational institutions, or financial platforms, that makes payments to non-U.S. persons must file Form 1042-S with the IRS. This is an essential part of staying tax-compliant and avoiding penalties.
Form 1042-S is used for reporting U.S.-source payments made to non-U.S. persons, along with any tax withheld under Chapters 3 (nonresident withholding) and/or 4 (FATCA). These payments can include:
Note: A separate 1042-S must be filed for each recipient, and each copy must be furnished to the recipient.
The IRS requires the payer or withholding agents to file the form with the IRS and furnish recipient copies by March 15 of the year after the payment is made.
Note: The 1042- S filing deadline moves to the next business day if March 15 falls on a holiday or weekend.
Special partnership rule: If a partnership withholds on a foreign partner after March 15, the due date can be moved to September 15 of that year.
If a withholding ageny is unable to meet the 1042-S deadline March 15, they can request for an extensionbefore the original deadline.

Important: Filing and furnishing are two separate actions. It is advisable to track both extensions and keep confirmation copies for your records.
E-filing is required if a payer files 10 or more information returns or the entire year.
Important: If you’re filing on paper, attach Form 1042-T to your 1042-S forms.
