What is Form 1042?

Form 1042 (different from Form 1042-S) is an “Annual Withholding Tax Return for U.S. Source Income of Foreign Persons.” The form is used to report tax withheld on certain income of foreign persons. Unlike Form 1042-S, this form only needs to be submitted to the IRS, not to payees. Form 1042 is required to be reported anytime a 1042-S form is issued, regardless of if taxes were withheld. 

Historically, the IRS did not allow electronic filings for Form 1042, forcing companies to file via paper mailings. However, since Tax Year 2022 allowed electronic filings through the IRS’ Modernized e-File (MeF) system. Starting with Tax Year 2024 reporting, the IRS will require US Withholding Agents to file Form 1042 electronically.
