Withholding Agents Vs. Intermediaries: Key Differences in Form 1042-S Reporting

reading time: 15 minute(s)

Form 1042-S plays a pivotal yet often overlooked role in international business transactions—serving as the critical bridge between U.S. businesses and their foreign counterparts. Whether it’s a global tech giant paying royalties overseas, a financial institution managing foreign investments, or a university providing scholarships to international students, the correct handling of Form 1042-S can profoundly impact business operations, compliance standings, and international relationships. 

Clearly identifying whether your organization acts as a withholding agent, a primary withholding agent, or an intermediary significantly influences your compliance obligations and reporting requirements.

Form 1042-S – Understanding the Basics

Form 1042-S, “Foreign Person’s U.S. Source Income Subject to Withholding,” is used to report income paid to foreign individuals who are subject to U.S. withholding tax. It covers a wide variety of income types, including interest income, dividends, rents, royalties, scholarships, and pension payments.

This form must be filed with the IRS and provided to the income recipient. Depending on how your business interacts internationally, your responsibilities in Form 1042-S reporting can vary greatly. Understanding these roles—whether as a withholding agent, primary withholding agent, or intermediary—helps clarify your compliance obligations and streamline the reporting process.

Who is a Withholding Agent?

A withholding agent is any individual, business, or entity responsible for withholding and remitting taxes on payments made to foreign persons that are subject to U.S. tax withholding under Chapter 3 (Withholding on Payments to Foreign Persons) and Chapter 4 (FATCA Withholding) of the Internal Revenue Code.

Responsibilities of a Withholding Agent:

1. Determining Tax Liability: The withholding agent must analyse whether a payment is subject to U.S. withholding tax and at what rate.
2. Withholding and Depositing Taxes: If withholding is required, the agent must deduct the applicable tax amount and deposit it with the IRS.
3. Filing Form 1042-S: Each payment made to a foreign entity or individual that is subject to withholding must be reported on Form 1042-S.
4. Maintaining Documentation: Withholding agents must collect valid Forms W-8 (such as W-8BEN, W-8BEN-E, and  W-8IMY) from payees to determine their tax residency status and applicable withholding rate.

Example: Stark LLC, a U.S.-based technology giant, licenses software from a developer in Ireland. As the withholding agent, Stark LLC must: Determine the applicable withholding tax rate based on U.S.-Ireland tax treaties. – Collect the required W-8BEN-E form from the Irish developer. – Withhold the correct tax amount from the royalty payments. – Submit the withheld amount to the IRS. – Issue Form 1042-S to the Irish developer and report payments on Form 1042 annually.

Who is Primary Withholding Agent?

Primary withholding agents hold a critical and direct responsibility in Form 1042-S compliance. They are typically the first point of contact with foreign payees and have a contractual obligation to manage tax withholding accurately and comprehensively.

Example: If Stark LLC has a subsidiary managing these software licensing transactions directly with the Irish company, that subsidiary acts as the primary withholding agent. It holds direct responsibility for withholding taxes, documentation, and reporting obligations to the IRS, fully accountable for compliance.

Who is an Intermediary?

An intermediary is an entity that receives payments on behalf of another foreign person. Unlike withholding agents, intermediaries are not always required to withhold tax, depending on their status. There are two main types of intermediaries:

Qualified Intermediary (QI)

A Qualified Intermediary (QI) is a foreign financial institution or other entity that has entered into an agreement with the IRS to manage U.S. tax withholding and reporting obligations.

• A QI can assume responsibility for withholding and reporting on behalf of its account holders.
• It can claim reduced withholding rates under tax treaties.
• QIs file Form 1042-S directly with the IRS and issue the form to their account holders.

Non-Qualified Intermediary (NQI)

A Non-Qualified Intermediary (NQI) is an entity that does not have a withholding agreement with the IRS.

• An NQI must pass relevant payee documentation (such as Forms W-8) to the withholding agent.
• It does not assume withholding responsibility; the withholding agent remains responsible for tax deductions and reporting.
• The withholding agent issues Form 1042-S directly to the final income recipient using information provided by the NQI.

Example: If Stark LLC pays royalties through an intermediary (e.g., an international financial firm): Qualified Intermediary (QI) – If the intermediary is a Swiss bank serving as a QI, it handles withholding and reporting directly. It independently applies treaty benefits to reduce withholding rates. – The QI files Form 1042-S directly with the IRS, simplifying Stark LLC’s responsibilities. Non-Qualified Intermediary (NQI) – If the intermediary is an international payment processor without a QI agreement, it forwards documentation from the foreign software developer to Stark LLC. – Stark LLC retains full responsibility for withholding taxes and reporting and files Form 1042-S based on the documentation received from the NQI.
