1042 Forms › Form 1042-S › Form 1042-S Instructions: Line-by-Line Filing Guide 2026
Form 1042-S reports U.S. source income paid to foreign persons and the tax withheld. This guide walks you through every box on the form with clear instructions for accurate completion.
Form 1042-S is more complex than domestic information returns because it must account for tax treaty benefits, Chapter 3 withholding, and Chapter 4 (FATCA) withholding. Accurate completion requires understanding income codes, exemption codes, and recipient status codes.
Form 1042-S contains the following main sections:
Enter the two-digit code identifying the type of income paid. Common income codes include:
| Code | Income Type |
|---|---|
| 01 | Interest paid by U.S. obligors - general |
| 04 | Interest on real property mortgages |
| 06 | Dividends paid by U.S. corporations - general |
| 07 | Dividends qualifying for direct dividend rate |
| 10 | Royalties - industrial (know-how) |
| 11 | Royalties - motion pictures/TV |
| 12 | Royalties - other (copyrights) |
| 14 | Real property income and natural resources royalties |
| 15 | Pensions, annuities, alimony |
| 16 | Scholarship or fellowship grants |

| 18 | Dependent personal services |
| 19 | Compensation for teaching |
| 20 | Compensation during studying/training |
| 28 | Gambling winnings |
