Do I Need to File Form 1042 if No Tax Was Withheld?
Introduction
Many withholding agents are unsure whether they must file Form 1042 when no tax was actually withheld from payments to foreign persons. The answer in most cases is yes. The IRS filing requirement is based on whether U.S.-source income was paid to a foreign person, not on whether tax was withheld. Form 1042 is the annual return that summarizes and reconciles all income and withholding activity reported during the year.
Understanding that zero withholding does not eliminate the filing requirement is essential for staying compliant and avoiding unnecessary IRS notices and penalties.
What Zero Withholding Really Means
Zero withholding simply means that, for a specific payment, the withholding rate applicable to the foreign recipient was zero. This may happen for several reasons.
A valid tax treaty may reduce the withholding rate to zero.
The income type may be exempt under the Internal Revenue Code.
The payee may have provided valid documentation such as Form W-8BEN or W-8BEN-E.
A refund or adjustment of previously withheld tax may have reduced the final withholding amount.
While withholding may be zero for these payments, the payments themselves are still reportable. That means a Form 1042-S is usually required for the payee, and a Form 1042 return is required for the withholding agent.
When Form 1042 Is Required Even With No Tax Withheld
A Form 1042 filing is required if any of the following occurred:
- You made a payment of U.S.-source income to a foreign person.
- You issued one or more Forms 1042-S during the year.
- You acted as a withholding agent for any payment subject to Chapter 3 or Chapter 4 rules.

The IRS does not base filing requirements on the amount of tax withheld. Instead, the requirement is tied to the underlying payments and your role as the withholding agent.
Examples of Common Zero-Rate Situations
There are several real-world situations where the withholding rate is zero, yet the filing requirement is still present.
- A foreign vendor performs work outside the United States and a tax treaty exemption applies.
- A foreign researcher receives a qualified scholarship that is exempt from withholding.
- A foreign investor receives portfolio interest which is generally exempt from withholding.
- Royalty payments qualify for a treaty rate of zero percent.
In each of these cases, the payment is still U.S.-source income, and therefore the withholding agent must file Form 1042 and issue Form 1042-S even when no tax is withheld.
IRS Reconciliation Expectations
Form 1042 must reconcile with the combined totals of all Forms 1042-S issued during the year. Total U.S.-source income paid, total withholding, and total deposits must match the amounts reported on Forms 1042-S. If the IRS receives payee statements but does not receive the corresponding annual summary return, or if the amounts do not reconcile, the IRS may issue a notice requesting correction or clarification.
Why Filing Zero-Withholding Returns Is Important
Submitting Form 1042 even when no tax is withheld helps demonstrate compliance with IRS requirements. Failure to file can result in:
- Late filing penalties.
- Requests for additional documentation.
- IRS notices questioning missing or incomplete returns.
- Potential withholding agent liability for unreported payments.
Proper filing ensures a complete record of payments to foreign persons and supports withholding decisions for future years.
Conclusion
A withholding agent may still need to file Form 1042 even when no tax was withheld. The filing requirement is based on whether U.S.-source income was paid to a foreign person and whether a Form 1042-S was required. Zero withholding does not eliminate the responsibility to file the annual Form 1042 return. Filing accurately and on time helps maintain compliance and reduces the risk of IRS notices or penalties.
