Is Your Organization Ready for Mandatory Electronic Filing of Form 1042?
Beginning with tax year 2023 filings (submitted in 2024), the IRS mandated electronic filing of Form 1042, Annual Withholding Tax Return for U.S. Source Income of Foreign Persons. Although the Service provided administrative relief in prior seasons by permitting paper filings, that relief should not be assumed to continue. With additional software providers now supporting Form 1042 electronic filing, the expectation is that compliance through electronic submission will be enforced for Form 1042 2025 filings.
Understanding the Filing System
Form 1042 must be filed through the IRS’s Internal Revenue Service Modernized e-File (MeF) platform. This is separate from the systems used for Form 1042-S.
Many organizations are familiar with submitting Forms 1042-S through:
Filing Information Returns Electronically (FIRE)
Information Returns Intake System (IRIS)
However, these platforms do not support Form 1042. MeF requires compatible software — either internally developed or obtained through a third-party provider. Without access to MeF-capable software, electronic filing will not be possible.
If You Are Not Ready — Immediate Steps to Consider
If your organization is not prepared to electronically file Form 1042 by the March 16 deadline (due to March 15th being on a Sunday), there are several options to evaluate.
1. Engage a Qualified MeF Provider
The Internal Revenue Service maintains a list of vendors that have successfully completed the IRS Assurance Testing System (ATS) for Form 1042 MeF submissions. See 1042 Modernized e-File (MeF) providers | Internal Revenue Service. While helpful, the list may not always reflect all available providers, as updates occur periodically.
Conducting independent due diligence in addition to reviewing the IRS list is advisable. Confirm that any provider you engage specifically supports Form 1042 MeF (not just Form 1042-S).
2. Submit a Hardship Waiver Request
Withholding agents experiencing legitimate barriers to electronic filing may request a hardship waiver. The request must be submitted prior to March 16th via fax, delivery service, or standard mail.
A complete waiver submission should include:
A summary of the actions taken to attempt timely compliance;
A plan outlining how the organization will meet the electronic filing requirement in future years; and
A detailed explanation of the undue hardship currently preventing electronic filing.
Importantly, the IRS expects a quantification of incremental costs associated with electronic filing compared to paper filing, along with an explanation of why those costs create a hardship.
Waiver approval is not automatic and requires thoughtful documentation. See Requesting a waiver from the electronic filing requirement of Form 1042.
3. File for an Extension
Organizations needing additional time may submit Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns, by March 16.
An approved Form 7004 provides a six-month extension to file Form 1042. However:
The extension applies only to the filing deadline.
Any tax due must still be paid by the original March 16 deadline.
An extension does not eliminate the electronic filing requirement but may provide critical time to implement a compliant solution.
Final Considerations
Electronic filing of Form 1042 through MeF is no longer theoretical — it is an operational requirement. Organizations that have relied on prior administrative flexibility should reassess their readiness immediately.
Confirm system access, validate vendor capabilities, and document contingency plans before the deadline approaches.
