What Form 1042 (2010) Is For
IRS Form 1042 (2010) is the annual withholding tax return used by withholding agents to report tax withheld on U.S. source income paid to foreign persons, including nonresident aliens, foreign corporations, foreign partnerships, foreign trusts, and foreign estates. The Internal Revenue Service requires this form to summarize income tax withholding and federal tax liability related to certain income subject to U.S. tax laws during the calendar year.
Form 1042 must be filed by any withholding agent responsible for reporting tax withheld on income paid, such as eligible deferred compensation items, scholarship or fellowship grants, or specified federal procurement payments. It also covers withholdable payments made to foreign financial institutions and qualified investment entities. The form works in conjunction with Forms 1042-S and 1042-T to ensure accurate reporting of tax withheld and compliance with IRS tax forms and regulations.

Step-by-Step (High Level)
Step 1: Gather Your Records
Gather all records of payments made to foreign persons, including Forms W-8BEN, income codes, and documentation of income subject to withholding and tax withheld. These records support accurate reporting and compliance with Internal Revenue Service requirements.
Step 2: Prepare Forms 1042-S
Prepare Form 1042-S for each foreign person or entity receiving payments subject to withholding. Each form must show the income paid, tax withheld, and any treaty benefits claimed under applicable tax laws.
Step 3: Complete Form 1042-T
If filing on paper, complete Form 1042-T to transmit all Forms 1042-S to the IRS. Ensure the totals reported match the income paid and federal tax withheld for the calendar year.
Step 4: Calculate Federal Tax Liability
Calculate the total federal tax liability for the year using the Record of Federal Tax Liability section on Form 1042. Enter each period’s tax withheld to confirm proper reporting of income and tax deposits.
Step 5: Reconcile Income Paid and Tax Withheld
Reconcile all income paid and tax withheld to ensure totals on Form 1042 align with the data reported on all Forms 1042-S. Accurate reconciliation prevents reporting errors and reduces the likelihood of IRS correspondence.
Step 6: Report Total Deposits
Report all federal taxes deposited through EFTPS or another approved system. Verify that the total tax deposited equals the total tax liability reported on the annual withholding tax return.
Step 7: Determine Balance Due or Overpayment
Determine if additional tax is due or if there is an overpayment. Overpayments may be credited toward the next calendar year or refunded, pending approval from the IRS.
Step 8: Sign and Mail Form 1042
Sign and mail the completed Form 1042 to the IRS Ogden Service Center by the due date or the next business day if it falls on a legal holiday. Retain copies and supporting records for at least three years.
Common Mistakes and How to Avoid Them
Many withholding agents make avoidable errors when filing Form 1042. The most frequent issues include:
- Failing to reconcile Forms 1042 and 1042-S: Always ensure totals on Form 1042 match the amounts reported across all Forms 1042-S before submission.
- Using the wrong identification number: Enter the correct QI-EIN, WP-EIN, or WT-EIN rather than a standard Employer Identification Number.
- Missing or late deposits: Review and follow the proper deposit schedule to avoid penalties for late or missed tax payments.
- Filing late or not filing because no tax was withheld: Form 1042 must still be filed even if no tax was withheld during the year.
- Incorrectly adjusting for overwithholding: Make adjustments for overwithheld amounts before the due date; late corrections are not permitted.
Withholding agents can avoid penalties and processing delays by reconciling all payment data, verifying identification numbers, and filing complete, accurate, and timely electronic returns.
