Ashford International Law P.C.

Summary

1. Banks, broker-dealers, trust companies, custodians and transfer agents meet cross-border estates at three points: when a foreign account holder dies, when an estate or trust they administer pays a beneficiary abroad, and whenever they pay income to a foreign person.
2. Whether an asset of a deceased nonresident is subject to United States estate tax depends on its situs. Shares of American companies, including American mutual funds, are United States assets; bank deposits, portfolio debt and shares of foreign companies are not. An estate tax treaty can remove the tax on American shares altogether.
3. A custodian may release the United States assets of a nonresident decedent only against an IRS transfer certificate, unless those assets were worth $60,000 or less at death or are administered by an executor appointed in the United States. A release without it exposes the institution to personal liability.
4. An estate or trust that distributes income to a foreign beneficiary is a withholding agent. It must withhold 30 percent, or a lower treaty rate, on the part of each distribution that carries out income subject to withholding, and 21 percent on gain from United States real property allocable to the foreign beneficiary.
5. Withholding on payments to foreign persons runs under several regimes at once, each with its own documentation, rate and return: chapter 3, FATCA, backup withholding, FIRPTA and the partnership rules.
6. Most errors arise from outdated or missing Forms W-8, from the assumption that the death of an account holder changes nothing, and from distributions made before the estate’s taxes are settled.

Part I. Where institutions meet cross-border estates

A United States financial institution rarely chooses to become involved in an international estate. The involvement follows from its role: it holds the securities of a customer who lives in Munich or Paris and dies there; it serves as trustee of a family trust whose beneficiaries have moved to Europe; it acts as transfer agent for an issuer whose shareholder has died abroad; or it administers an American estate with heirs in several countries. In each role the institution carries legal risk of its own. The Internal Revenue Code treats a person in possession of a decedent’s property as an executor for estate tax purposes if no executor is appointed in the United States (IRC § 2203), makes recipients of estate property personally liable for unpaid estate tax (IRC § 6324(a)(2)), and holds a withholding agent liable for tax it should have withheld (IRC § 1461). A fiduciary who pays other claims or distributions before the federal tax claims is personally liable to the extent of the payment (31 U.S.C. § 3713(b)).

The firm advises institutions on these questions in individual cases and on their procedures: account documentation, the handling of a foreign customer’s death, distributions from estates and trusts to beneficiaries abroad, and the correction of past withholding and reporting.

Part II. United States situs and non-United States situs assets

A person who was neither a United States citizen nor domiciled in the United States is subject to United States estate tax only on property situated in the United States, with an exemption equivalent to $60,000 and rates up to 40 percent (IRC §§ 2101, 2102(b), 2103). The situs rules are statutory and do not follow the location of the account.

Cash in a brokerage account is treated as a bank deposit only if it is actually held with a bank, for example through a sweep program. The gift tax reaches less: a nonresident’s gift of shares or other intangible property is not subject to United States gift tax at all (IRC § 2501(a)(2)).

Treaty relief. The United States has estate tax treaties with fifteen countries. The modern treaties with Germany, France, the United Kingdom, Austria, Denmark and the Netherlands allow the United States to tax a decedent domiciled in the other country essentially only on United States real property and on the property of a business carried on through a permanent establishment in the United States. For a German or French customer’s portfolio of American shares, the treaty removes the United States estate tax. The estate must still claim the exemption, usually on Form 706-NA with a treaty disclosure, and the institution still needs a transfer certificate before it releases the assets. The treaties and their credit provisions are described on the page on nonresidents with U.S. assets.

Part III. Death of a foreign account holder: release of the assets

A custodian, transfer agent or other holder may not transfer the property of a nonresident non-citizen decedent without a transfer certificate issued by the IRS (Treas. Reg. § 20.6325-1). The IRS issues the certificate when it is satisfied that the estate tax, if any, has been paid or provided for. Two exceptions apply. No certificate is required if the value of the decedent’s United States gross estate at death did not exceed $60,000 (reduced by certain taxable gifts); the holder is protected if it first receives a statement of the relevant facts from the executor or another responsible person and has no information to the contrary. And no certificate is required for property administered by an executor or administrator appointed, qualified and acting in the United States.

The certificate is requested with Form 706-NA, where that return is required, or with an affidavit and supporting documents where it is not. The IRS states that it needs 12 to 18 months to process an affidavit once all documents are received. Institutions should explain that timeline to the heirs at the outset, because the certificate, not the estate’s foreign court documents, is what permits the release.

Foreign documents of succession raise a second question. A German certificate of inheritance (Erbschein) or a European Certificate of Succession identifies the heirs under the law of the decedent’s residence, but it is not a letter of administration from a United States court, and it does not bind an American transfer agent. Depending on the value and the state, the heirs may need an ancillary probate, a small estate affidavit or an indemnity, in addition to the transfer certificate. Institutions that accept foreign documents should have a documented policy on which documents they accept, with translations and apostilles, and on the indemnities they require.

Part IV. Distributions to foreign beneficiaries

A United States estate or trust that makes distributions to a nonresident beneficiary is a withholding agent, whether the fiduciary is an individual, a trust company or a bank. The obligations follow from the character of what is distributed.

• Income subject to withholding. To the extent a distribution carries out distributable net income consisting of fixed or determinable annual or periodical income, such as dividends, rents or non-portfolio interest, the fiduciary withholds 30 percent (IRC §§ 1441, 871(a); Treas. Reg. § 1.1441-5). The beneficiary can claim a reduced treaty rate on Form W-8BEN; under the treaty with Germany, dividends are generally subject to 15 percent and interest to 0 percent.
• Income exempt from withholding. Portfolio interest and bank deposit interest retain their exemption when they pass through the estate or trust (IRC §§ 871(h), 871(i)).
• Capital gains. Gain on the sale of securities is generally not taxable to a nonresident beneficiary who was not present in the United States for 183 days or more in the year (IRC § 871(a)(2)), and in most trusts the gain is allocated to principal rather than distributed.
• United States real property. A domestic estate or trust that sells United States real property must withhold 21 percent of the gain allocable to foreign beneficiaries when it distributes or credits that amount (IRC § 1445(e)(1); Treas. Reg. § 1.1445-5(c)), and report it on Forms 8288 and 8288-A.
• Principal. A distribution of principal that carries out no income is not subject to withholding, but the fiduciary must be able to show that the income for the year has been accounted for.

The distributed income is reported to the foreign beneficiary on Form 1042-S, not on Schedule K-1 alone, and the fiduciary files Form 1042 for the year. Before any distribution to heirs abroad, the fiduciary should also confirm that the estate’s own income, estate and gift tax liabilities are paid or reserved, because a distribution that leaves the government unpaid is the fiduciary’s personal liability under 31 U.S.C. § 3713(b). A beneficiary resident in Germany is separately subject to German inheritance tax and must notify the German tax office within three months (§ 30 ErbStG); the institution does not withhold German tax, but requests for documentation from German heirs are common and should be anticipated.

Part V. Withholding requirements

Several withholding regimes apply side by side, and a single payment can fall under more than one of them.

Documentation. A Form W-8BEN generally remains valid until the last day of the third calendar year after the year in which it was signed, unless a change in circumstances makes the information on it incorrect (Treas. Reg. § 1.1441-1(e)(4)(ii)). The death of the account holder is such a change: from that date the payee is the estate, which must be documented in its own right, as a foreign estate on Form W-8BEN-E or as a United States estate on Form W-9. Where documentation is missing, the presumption rules of Treas. Reg. § 1.1441-1(b)(3) decide whether the payee is treated as a United States person subject to backup withholding or as a foreign person subject to 30 percent withholding. A trust must be documented according to its type: a grantor or simple foreign trust generally provides Form W-8IMY with information on its owners or beneficiaries, and a complex foreign trust provides Form W-8BEN-E.

Correction. Under-withholding is the withholding agent’s liability, and over-withholding can only be refunded through the adjustment procedures or by the payee’s own claim. Errors found in a review of the account files should be corrected in the current year where the adjustment rules allow it and disclosed on amended Forms 1042 and 1042-S where they do not.

Part VI. Practical steps

1. Flag accounts of foreign persons and accounts with foreign beneficiaries or trust beneficiaries, and track the expiry of each Form W-8.
2. On notice of the death of a foreign account holder, restrict the account, determine the value of the United States situs assets as of the date of death, and ask the executor for the facts needed to decide whether a transfer certificate is required.
3. Where the decedent was domiciled in a treaty country, inform the executor that the treaty exemption must still be claimed and that the transfer certificate is still needed.
4. Obtain new documentation for the estate or the heirs before any payment after the date of death.
5. Before a distribution from an estate or trust to a beneficiary abroad, determine the income character of the distribution, the applicable treaty rate and any FIRPTA amount, and confirm that the estate’s own taxes are paid or reserved.
6. File Forms 1042, 1042-S, 8288 and 8288-A on time and reconcile them with the Schedules K-1.
7. Maintain a written policy on foreign succession documents, translations, apostilles and indemnities.

Conclusion

For a financial institution, a foreign customer’s death or a beneficiary’s move abroad turns a routine account into a matter of personal liability. The rules on situs, transfer certificates and withholding are technical but largely predictable, and the treaties often reduce the tax to nothing. What causes loss is the timing: releasing assets before the certificate is issued, paying a distribution before the income and the estate tax are accounted for, or relying on documentation that ceased to be valid on the date of death.
