Understanding ITIN Requirements for Beneficiaries

If you are a non-U.S. person who is a beneficiary of a U.S. estate, trust, or retirement account such as a 401(k) or IRA from TIAA, Charles Schwab, Morgan Stanley, Fidelity, you may be required to obtain an Individual Taxpayer Identification Number (ITIN) before any distributions can be made. U.S. estate administrators, trustees, and financial institutions are obligated to report and withhold taxes on income distributed to foreign individuals.

When Is an ITIN Required as a Beneficiary?

An ITIN is required in the following scenarios:

  • You are a foreign beneficiary receiving U.S. source income through an estate, trust, or retirement distribution.
  • The executor or trustee of the estate or trust must file Form 1041 and issue Schedule K-1 in your name.
  • A financial institution is required to issue Form 1042-S for distributions such as retirement income or investment income and requests a valid U.S. tax ID.
  • You wish to claim a refund of withheld taxes or apply for reduced withholding under an applicable tax treaty.

Without an ITIN:

  • U.S. withholding agents may be forced to withhold tax at the default 30% rate.
  • You may face delays in receiving your inheritance or distributions.
  • You will be unable to file a 1040NR tax return or claim any tax treaty benefits.

Supporting Documentation for ITIN Application:

To apply for an ITIN as a beneficiary, you must submit:

  • Form W-7 – Application for IRS Individual Taxpayer Identification Number.
  • Proof of identity and foreign status – e.g., an original passport or a certified copy from the issuing agency.
  • Supporting documentation such as:
    • A letter from the executor or trustee requesting an ITIN for reporting purposes.
    • A copy of the will or trust document naming you as a beneficiary.
    • For inherited 401(k) or IRA distributions, a distribution notice or letter from the financial institution.
    • If applicable, any Form 1042-S issued in your name.
