What Form 1042-S Is For
IRS Form 1042-S (2024) reports U.S.-source income paid to foreign persons, including nonresident aliens, foreign corporations, and other entities subject to withholding. It shows the income paid, federal tax withheld, and any tax treaty benefits claimed. The form covers FDAP income—such as interest, dividends, rents, royalties, and specific service fees. Unlike Forms 1099 or W-2, it applies to cross-border payments even when no tax is withheld.
Each payment must be reported separately to ensure full compliance with IRS regulations. Access the IRS Form Help Center for guidance on international reporting requirements, withholding forms, and verification documents needed when filing Form 1042-S.

Step-by-Step Filing Process (High Level)
Filing IRS Form 1042-S (2024) requires careful attention to detail to ensure full tax compliance with the Internal Revenue Service. The following is a simplified overview of the process for filing as a withholding agent:
- Confirm Your Role: Determine if you are a withholding agent, designated withholding agent, or primary withholding agent responsible for reporting source income subject to U.S. tax.
- Identify Payments: Review all federal procurement payments, specified federal procurement payments, eligible deferred compensation items, scholarship or fellowship grants, and other certain income made to foreign persons, foreign estates, or withholding foreign partnerships.
- Apply Correct Withholding: Calculate the proper tax rate based on effectively connected income, backup withholding, or claiming treaty benefits. Include any state income tax withheld or tax paid.
- Complete the Form: Enter the withholding agent’s name, employer identification number, income codes, and payment details. Report transactions involving foreign financial institutions, qualified investment entities, publicly traded partnerships, or foreign withholding trusts.
- Submit and Reconcile: File electronically through the FIRE System. Ensure that adjustments for withheld tax, own funds, or the foreign partner's share are accurately displayed.
- Maintain Records: Keep documentation, including any federal tax return or central withholding agreement, for at least three years to verify tax withheld and prevent unpaid tax issues.
Common Mistakes and How to Avoid Them
Even experienced filers can make mistakes when completing IRS Form 1042-S (2024). Below are common errors and how to prevent them:
- Missing or Incorrect Identification: Mistakes in the withholding agent’s name or employer identification number delay processing. Ensure all identification details are verified before submission.
- Wrong Income Classification: Misreporting eligible deferred compensation items, dependent personal services, or scholarship or fellowship grants under incorrect income codes leads to mismatches. Use current IRS instructions to classify each payment accurately.
- Filing the Wrong Form Type: Confusing federal procurement payments with specified federal procurement payments or omitting state income tax withholding causes reporting errors. Review all tax forms before filing.
- Reporting Errors: Failing to report tax withheld or overwithheld tax repaid can create compliance issues. Reconcile totals with your federal tax return and payment records.
- Omissions in Entity Reporting: Missing data for foreign financial institutions, withholding foreign partnerships, or publicly traded partnerships is common. Confirm all source income subject to withholding before e-filing to maintain tax compliance.
