What Form 1042 (2024) Is For
Form 1042 (2024) is filed by every withholding agent or financial institution that makes payments of income subject to U.S. tax withholding. These include federal procurement payments, withheld payments, or dependent personal services paid to foreign persons. It documents the total tax withheld and tax paid, serving as a reconciliation of the federal tax and state income tax withheld during the year. Entities with foreign branches or foreign partnerships need to use this federal tax return to maintain tax compliance.
When You’d Use Form 1042 (2024)
A withholding agent must file Form 1042 when paying U.S.-source income to non-U.S. individuals or entities. This includes effectively connected income, substitute dividend payments, or notional principal contracts. The due date for the 2024 annual withholding tax return is March 17, 2025. If the due date falls on a legal holiday, filing is due the next business day. Filing extensions may be requested using Form 7004, but the delay does not extend the time to pay any federal taxes owed.

Step-by-Step (High Level)
Step 1: Gather documentation
Collect all Forms 1042-S, EFTPS deposit records, and documents showing income subject to withholding. Include records from foreign entities, foreign partnerships, or financial institutions in territories that have U.S. source transactions.
Step 2: Enter withholding agent information
Provide your withholding agent’s name, address, foreign postal code, and identification numbers. Ensure that your employer identification number and foreign tax identification number are entered correctly to ensure proper tax compliance.
Step 3: Report gross income and tax withheld
In Section 1, record gross income, tax withheld, and tax deposited for each payment period. These figures must match your federal tax liability for that period.
Step 4: Reconcile payments and deposits
Compare totals from all Forms 1042-S with your annual withholding tax return data. Verify that the federal tax withheld equals the total tax paid and the income subject reported.
Step 5: Review and file the return
Sign the form under penalties of perjury. The primary withholding agent or designated withholding agent must ensure accuracy before submitting to the Internal Revenue Service electronically or by mail.

What Happens After You File
After submission, the Internal Revenue Service cross-checks your annual withholding tax return with reported Forms 1042-S, EFTPS deposits, and federal taxes. If inconsistencies appear, you may receive a notice requesting clarification. Keep copies of your return, flow-through entity records, and proof of tax deposited for at least four years. Withholding agents must retain all documentation related to foreign persons, foreign partnerships, and foreign trusts to demonstrate compliance with applicable regulations.
