Living outside the US: When IRS Form 56 becomes important

Living abroad does not prevent someone from acting as an executor, trustee, guardian, or other fiduciary for a US taxpayer or estate. When that role begins, IRS Form 56 tells the Internal Revenue Service who has assumed the taxpayer’s powers, rights, duties, and privileges for specified federal tax matters.
What does Form 56 actually do?
Form 56 is titled “Notice Concerning Fiduciary Relationship.” It notifies the IRS that a person is acting in a fiduciary capacity for another individual or entity under Internal Revenue Code sections 6036 and 6903.
The form does not appoint an executor, create a trust, or grant authority by itself. Authority normally comes from a will, trust instrument, court order, statute, or other governing document. Form 56 reports that relationship to the IRS so the fiduciary can handle the relevant federal tax responsibilities.
For a straightforward introduction to What is IRS Form 56, taxpayers abroad can review the form’s purpose before assembling the supporting records.
Who is considered a fiduciary?
A fiduciary is someone who stands in the taxpayer’s place and is legally responsible for handling specified property or tax affairs. Common examples include:
- an executor or administrator of a deceased person’s estate;
- a trustee managing a trust;
- a court-appointed guardian or conservator;
- a receiver or assignee for the benefit of creditors; or
- another person holding a comparable legal duty.
Being a relative, beneficiary, accountant, or informal helper does not automatically make someone a fiduciary. A surviving spouse is not necessarily the executor. The person should confirm the source and scope of their legal authority before signing a federal notice under penalties of perjury.
Why does the form matter when someone lives abroad?
An overseas fiduciary may need to receive IRS correspondence, request records, sign returns, respond to notices, claim a refund, or manage tax debts. Form 56 helps the IRS recognise the person who has authority to act.
Foreign residence does not change the form’s basic purpose, but it raises practical issues. International mail can be slow, documents may require court certification, and local probate terminology may not match US terminology. The fiduciary should use a reliable mailing address and retain copies of every submission and delivery record.
What information appears on Form 56?
The fiduciary identifies the person or entity for whom they are acting, provides the relevant taxpayer identification number, states the fiduciary’s own details, and describes the authority creating the relationship. The form also identifies the taxes, forms, and years involved.
Each fiduciary generally files a separate Form 56. Likewise, a separate form is used for each person or entity represented. An executor who will file both the decedent’s final Form 1040 and the estate’s Form 1041 may therefore file one Form 56 for the deceased individual and another for the estate.
Form 56 is not a power of attorney
Confusing fiduciary status with third-party authorisation is a common mistake.
| Form | Main purpose |
| Form 56 | Notifies the IRS of a legal fiduciary relationship |
| Form 2848 | Authorises an eligible representative to act before the IRS |
| Form 8821 | Permits another person to inspect or receive specified tax information |
A fiduciary may appoint a tax professional using Form 2848 after establishing the authority to act. Form 56 and evidence of appointment may need to accompany that authorisation. By contrast, a professional does not become the taxpayer’s fiduciary merely by preparing a return.
When and where should Form 56 be filed?
The IRS generally instructs a fiduciary to file Form 56 when the relationship is created or terminated. For an estate, it should be filed as soon as the necessary information, including the estate’s identification number where applicable, is available.
The form normally goes to the IRS service centre where the represented person or entity files its returns. The correct address depends on the underlying return and current instructions.
Form 56 is only a notice. It does not replace the decedent’s final Form 1040, the estate’s Form 1041, an estate-tax return, or a separate refund claim when otherwise required.
Remember to end or update the relationship
The IRS continues to treat the fiduciary relationship as active until notified otherwise. When duties end, a successor is appointed, or the relevant proceeding finishes, another Form 56 should report the termination or change.
This step protects both the estate and the outgoing fiduciary. Without an update, notices may continue going to the wrong person, creating avoidable delays or uncertainty about responsibility.
A practical overseas checklist
Before submitting the form, an overseas fiduciary should:
- confirm the legal basis of the appointment;
- obtain the taxpayer and estate identification numbers;
- identify every return, tax type, and period covered;
- attach or retain evidence of authority;
- verify the current IRS filing address;
- keep a complete copy and proof of delivery; and
- calendar the eventual termination notice.
Form 56 is short, but its function is significant. For people living outside the United States, filing it correctly creates a clear administrative bridge to the IRS while complex personal or estate matters are handled across borders.
