Use Form 1042, Annual Withholding Tax Return for U.S. Source Income of Foreign Persons, to report tax withheld on certain income of foreign persons, including nonresident aliens, foreign partnerships, foreign corporations, foreign estates, and foreign trusts. Form 1042 is a calendar year tax return. There are no provisions for filing a fiscal-year form. Form 1042 could be filed separately and does not have to be accompanied by Form 1042-T.
Use Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding, to report payments made to foreign persons, including nonresident aliens, foreign partnerships, foreign corporations, foreign estates, and foreign trusts. Caution! Carefully review the Instructions for Form 1042-S and ensure that the proper Form 1042-S is used for income paid during that year. For example, the 2015 Form 1042-S must be used to report income paid in 2015.
Use Form 1042-T, Annual Summary and Transmittal of Forms 1042-S, to transmit paper Forms 1042-S to the Internal Revenue Service. Use a separate Form 1042-T to transmit each type of Form 1042-S.
Foreign Account Tax Compliance Act (FATCA). The Form 1042, Form 1042-S and Form 1042-T were modified in 2014 primarily for withholding agents to report payments and amounts withheld under the provisions commonly known as FATCA (or Chapter 4 of the Internal Revenue Code), in addition to those payments and amounts required to be reported under Chapter 3 of the Internal Revenue Code.
The Forms 1042, 1042-S and 1042-T must be filed by March 15 of the year following the calendar year in which the income subject to reporting was paid. If March 15 falls on a Saturday, Sunday, or legal holiday, the due date is the next business day.
Who Must File
Every withholding agent or intermediary, whether U.S. or foreign, who has control, receipt, custody, disposal or payment of any fixed or determinable, annual or periodic U.S. source income must file.
File only one Form 1042 consolidating all Form 1042-S recipient information, regardless of the number of different clients, branches, divisions, or types of income for which you are the withholding agent.
Do not attach paper Forms 1042-S with your Form 1042. Form 1042 could be filed separately and does not have to be accompanied by Form 1042-T with attached paper Form(s) 1042-S.
Where to File
You must file these forms with the:
Ogden Service Center
P.O. BOX 409101
Ogden, UT 84409
You must use Form 1042-T to transmit paper Forms 1042-S. Use a separate Form 1042-T to transmit each type of Form 1042-S. If you have 250 or more Forms 1042-S to file, follow the instructions under Electronic Reporting.
