Form 1042 is an annual IRS return used to report and reconcile federal tax withheld on payments made to foreign persons. It applies to U.S.-source income paid during the calendar year and is filed by withholding agents responsible for those payments.
The form covers multiple types of withholding under different IRS rules, including Chapter 3 withholding on income paid to foreign individuals and entities, Chapter 4 (FATCA) withholding on certain foreign financial transactions, Section 5000C withholding on payments to foreign persons under U.S. government contracts, and Section 877A withholding on certain payments made to covered expatriates.
Any withholding agent that receives, manages, has possession of, disburses, or pays a withholdable payment or an amount subject to withholding must file Form 1042.
Additional filing triggers include:
You must file even if no tax was actually withheld, as long as you had a reporting obligation for the calendar year. The obligation to file is based on your status and activity as a withholding agent or intermediary.

Form 1042 is filed annually with the IRS for the preceding calendar year. There is no minimum dollar threshold. The obligation to file depends on your status as a withholding agent, not the size of your payments.

No, there is no dollar threshold for Form 1042. The requirement to file is based solely on your status and activity as a withholding agent or intermediary. Once you have a reporting obligation for U.S.-source income paid to foreign persons, Form 1042 must be filed regardless of the amount.
A withholding agent is any person or business responsible for handling payments made to foreign persons that may be subject to U.S. tax withholding. This can include businesses, partnerships, corporations, trusts, government agencies, nonprofits, and even individuals if they control or make the payment.
The IRS charges a failure-to-file penalty of 5% of the unpaid tax per month (up to 25%), plus a separate failure-to-pay penalty of 0.5% per month. A separate late payment penalty of 0.5% per month, also capped at 25%, applies if tax is not paid when due. Interest accrues on unpaid tax from the original due date, even if an extension to file was granted.
