When you deal with cross-border payments, Form 1042-S quickly becomes more than just another IRS requirement. It sits at the center of how the IRS tracks U.S. source income paid to foreign persons and how withholding is handled under two major tax frameworks, Chapter 3 and Chapter 4.
If you assume Form 1042-S is only about reporting income, you might miss the bigger picture. This form also reflects withholding responsibility, recipient classification, compliance status, and documentation accuracy. One wrong code or a mismatch can trigger notices, penalties, or rework later.
Chapter 3 withholding: The basics everyone should know
Chapter 3 withholding focuses on what type of income is paid and who receives it. It generally applies when you make U.S. source payments to foreign individuals or entities.
Most commonly, this includes FDAP income, such as:
- Interest
- Dividends
- Royalties
- Rents
- Certain service payments
Under Chapter 3, the default withholding rate is 30%, unless a reduced rate or exemption applies. Reductions usually come from tax treaties, while exemptions depend on income type or recipient status.
Chapter 4 (FATCA) Withholding: What it means for reporting
Chapter 4, commonly known as FATCA, works very differently. Instead of focusing on income type, it focuses on compliance and documentation.
Chapter 4 applies to withholdable payments made to:
- Foreign Financial Institutions (FFIs)
- Certain Non-Financial Foreign Entities (NFFEs)
If proper FATCA documentation is missing, invalid, or not provided, a 30% FATCA withholding may apply, even if the payment could otherwise qualify for a lower rate under Chapter 3.
When payments fall under both chapters: Reporting without confusion
When a payment falls under both chapters, Chapter 4 takes priority and determines whether FATCA withholding applies. This priority affects how withholding is calculated, not how the payment is classified.
To report the payment correctly, you need to:
- Identify the applicable chapter
- Select the correct chapter indicator
- Apply the appropriate status and exemption codes
Understanding status codes: How roles affect chapters 3 and 4 withholding
Status codes tell the IRS who the recipient is and how they are classified for withholding purposes. These codes play a key role in determining whether Chapter 3 or Chapter 4 applies and whether withholding is required.
Common chapter 3 recipient status codes
The following status codes are commonly used when Chapter 3 withholding applies:
- Individual (Code 01): Used when the recipient is a foreign individual.
- Corporation (Code 02): Applies to foreign corporations receiving U.S.-source income.
- Partnership (Code 04): Used for foreign partnerships.
- Trust or Estate (Code 05): Applies when income is paid to a foreign trust or estate.
- Qualified Intermediary (QI) (Code 07): Used when payments are made through a QI that has assumed withholding responsibility.
- Nonqualified Intermediary (NQI) (Code 08): Used when the intermediary does not assume withholding responsibility.
These codes determine how withholding is calculated and reported under Chapter 3 rules.
Common chapter 4 recipient status codes
Chapter 4 status codes focus on the recipient’s FATCA classification and determine whether FATCA withholding applies:
- Participating FFI (Code 01): Indicates a foreign financial institution that complies with FATCA requirements.
- Registered Deemed-Compliant FFI (Code 02): FFIs that meet FATCA obligations without full participation.
- Nonparticipating FFI (Code 03): Subject to FATCA withholding.
- Active NFFE (Code 04): Generally not subject to FATCA withholding.
- Passive NFFE (Code 05): May be subject to withholding if required documentation is missing or incomplete.
- Exempt Beneficial Owner (Code 06): Includes governments, international organizations, and certain retirement funds.
Exemption codes: How to reduce withholding without confusion
Exemption codes explain why withholding is reduced or not applied. They are required and must align with the documentation.
Common chapter 3 exemption codes
Under Chapter 3, exemption codes are used when withholding is reduced based on the type of income or the recipient’s tax status. For Chapter 3 withholding, common exemption codes include:
- Code 01 – Income effectively connected with a U.S. trade or business.
- Code 02 – Tax treaty exemption applied.
- Code 04 – Exempt income under the Internal Revenue Code.
- Code 05 – Income paid to exempt organizations.
These codes justify reduced or zero withholding under Chapter 3.
Common chapter 4 exemption codes
Chapter 4 exemption codes are tied to FATCA classification, not income type. Some of the common codes include:
- Code 13 – Exempt beneficial owner under FATCA.
- Code 15 – Payments to participating or deemed-compliant FFIs.
- Code 16 – Payments to active NFFEs.
Without valid and current FATCA or withholding certificates, such as the appropriate W-8 form, the exemption cannot be applied, even if the code appears to fit the payment.
