• IRS Penalties for Late Filing: Failure to e-file by the deadline may result in penalties based on the lateness of the filing, which can range from $50 to $290 per form, depending on when the form is submitted. 

• State Filing Requirements: Some states have additional reporting requirements, so businesses should verify their obligations beyond federal filing. 

 

Form 1042 E-Filing Deadline 2025 

The e-filing deadline for Forms 1042-S and 1042 is March 15 of each year. Form 1042-S reports income subject to withholding under U.S. tax laws, while Form 1042 is used by withholding agents to report tax withheld on payments to foreign persons. To avoid penalties, ensure accurate filing by the due date. If needed, filers can request an extension using Form 8809 for Form 1042-S and Form 7004 for Form 1042. 

Here is a table outlining the e-filing deadlines for Forms 1042-S and 1042: 

Form	Description	E-Filing Deadline	Extension Form
