Understanding Form W-8IMY
- Form W-8IMY is an IRS document used by foreign intermediaries, flow-through entities, or certain U.S. branches to certify their status for withholding tax purposes.
- Unlike other W-8 forms, such as W-8BEN, W-8BEN-E, or W-8EXP, the W-8IMY is not used to claim a reduction or exemption from withholding tax.
- Instead, its primary purpose is to document the entity’s status as an intermediary, which may pass through income to its beneficial owners. This allows withholding agents to apply the correct withholding tax rules when payments flow through the intermediary to the ultimate beneficial owners.
What Information is Required to Complete Form W-8IMY?
When your recipients fill out Form W-8 IMY, they must provide the following key information:
-
1. Entity Identification
- Name of the organization (intermediary or flow-through entity)
- Country of incorporation or organization
- Name of a disregarded entity (if applicable)
- Chapter 3 (e.g., Qualified Intermediary, Nonqualified Intermediary, U.S. Branch, etc.) and Chapter 4 (FATCA status, e.g., Participating FFI, Nonparticipating FFI, Active NFFE, Passive NFFE, etc.)
-
2. Address Details
- Permanent address (no P.O. box)
- Mailing address (if different)
-
3. Tax Identification
- U.S. TIN (if required)
- Foreign TIN
- GIIN (if applicable)
- Reference number(s), if needed
-
4. Authorization
- Signature and date by an authorized representative certifying that the information is accurate
What Happens if Form W-8 IMY is Not Provided?
If a foreign intermediary, flow-through entity, or U.S. branch does not provide a completed Form W-8IMY to the withholding agent:
- Backup Withholding Applies: The withholding agent is required by the IRS to apply the full statutory withholding rate on payments subject to U.S. tax (typically 30% for U.S.-source income).
- No FATCA Relief: Without the form, the withholding agent cannot apply any reduced withholding rates or exemptions under FATCA or a tax treaty.
- Payment Delays or Rejection: Payments to the entity may be delayed until the form is received and verified, or the agent may refuse to release the funds.
- Reporting Implications: The entity may be reported to the IRS as a “non-compliant” recipient, which could trigger additional scrutiny or penalties.

What is a Qualified Intermediary (QI)?
