What Form 1042 Is For
Form 1042 (2022) is the annual withholding tax return that U.S. withholding agents use to report income paid to foreign individuals during the calendar year. It summarizes the tax withheld and tax paid to the Internal Revenue Service for various types of source income, including interest, dividends, royalties, pensions, and personal services income. A withholding agent can be any financial institution, corporation, or entity that makes amounts paid to foreign corporations, foreign partnerships, foreign estates, or foreign trusts.
When You’d Use Form 1042
You must file Form 1042 if your organization acts as a withholding agent and pays source income subject to U.S. tax withholding to a foreign person. For tax purposes, the due date for the 2022 tax year was March 15, 2023. Extensions were available using Form 7004, though any unpaid tax was still due by that date. If you missed the deadline, reasonable cause may reduce penalties. If errors are found, you must file a separate form clearly marked “Amended.”
Key Rules or Details for 2022

- Withholding agent’s chapter codes: Each withholding agent’s name and status under Chapter 3 or 4 must be accurately reported. Withholding agents must provide both codes, even if reporting only one type of withholdable payment.

Step-by-Step (High Level)
Step 1: Gather information
Collect payment data for all foreign persons and foreign entities for the preceding calendar year, including gross income, amounts subject to withholding, and all related tax withheld. Confirm your employer identification number and ensure your financial institution records match IRS requirements.
Step 2: Prepare Forms 1042-S
Before completing Form 1042, prepare Forms 1042-S for each foreign person receiving U.S. source income. These forms report amounts paid, gross amount, and withholding tax details.
Step 3: Record tax liability
Enter your total tax liability by quarter-monthly periods. The gross income reported here should reflect the income paid when the payment occurred, not when the deposit was made.
Step 4: Report payments and deposits
In the section for report payments, summarize the total withholdable payments and the tax deposited. Ensure that these totals reconcile with Forms 1042-S and verify that all income subject to withholding is properly listed.
Step 5: Calculate totals and sign
Combine your Chapter 3 and Chapter 4 tax liability, account for any unpaid tax, and confirm that federal tax liability amounts are correct. An authorized person must sign the form. You may file it electronically or mail it to the IRS Ogden Service Center.

Common Mistakes and How to Avoid Them
- Incorrect employer identification number: Always verify that your withholding agent’s name and employer identification number match IRS records to prevent rejection notices.
- Incomplete status codes: Ensure that both Chapter 3 and Chapter 4 status codes are completed to identify the withholding agent type and avoid IRS delays accurately.
- Reporting errors in tax liability: Enter the correct gross amount and tax liability for each period. Double-check that your liability totals match your deposits to avoid mismatch penalties.
- Failure to account for treaty benefits: Apply treaty benefits only when proper documentation exists to ensure correct tax withholding and avoid underpayment.
- Missing report payments section: Always complete the report payments section to show all source income and certain income paid during the year.
- Using outdated forms: Use the Form 1042 (2022) version to ensure proper calculation of federal tax liability.
- Math or timing errors: Ensure that each business day's entry reflects an accurate tax deposit and that totals reconcile across the annual withholding tax return.

What Happens After You File
After filing, the IRS reviews the annual withholding tax return for accuracy and consistency with Forms 1042-S. The Internal Revenue Service may assess additional tax if tax liability or tax deposited amounts differ. If you have overpaid, you may request a refund or apply the excess amount toward the next tax year. Retain copies of all records, the foreign partner’s share statements, and backup withholding documentation for at least four years.
