What is IRS Form 56 and who needs to file it?
IRS Form 56 is used to notify the IRS that you are acting on behalf of another taxpayer, estate, or trust as a fiduciary. Executors, trustees, guardians, and certain court-appointed representatives commonly file Form 56.
If you have been named the executor of a parent’s estate, appointed as the trustee of a trust, or given legal authority to manage another person’s financial affairs, you may need to file IRS Form 56.
Understanding when Form 56 applies can help avoid delays, communication problems with the IRS, and confusion about who has authority to act.

What is IRS Form 56?
IRS Form 56, Notice Concerning Fiduciary Relationship, notifies the IRS that a fiduciary relationship has been created or terminated.
A fiduciary is a person who has legal authority to act on behalf of another person or entity. In the eyes of the IRS, a fiduciary generally assumes the rights, responsibilities, and obligations of the taxpayer for the matters covered by the appointment.
Common fiduciaries include:
- Executors of estates
- Personal representatives
- Trustees
- Guardians
- Conservators
- Receivers
The IRS uses Form 56 to recognize who is acting in a fiduciary capacity for certain tax matters, although it is not used simply to request copies of IRS notices.
Do I need IRS Form 56?
Most US citizens living abroad do not need IRS Form 56 unless they are acting on behalf of another taxpayer, estate, or trust.

Situations where Form 56 is not required
You generally do not need Form 56 simply because you:
- Live outside the United States
- Own foreign bank accounts
- File Form 8938
- Claim foreign tax credits
- Own foreign investments
- Use a tax professional
These situations involve your own tax obligations rather than acting in a fiduciary capacity.
Who needs to file IRS Form 56?
Form 56 is commonly filed by fiduciaries who have legal authority to act for another taxpayer.
- Executors and personal representatives
- One of the most common uses of Form 56 occurs after a taxpayer dies. An executor or personal representative often files Form 56 to notify the IRS that they are responsible for handling tax matters related to the decedent’s estate.
- Trustees
- Trustees may file Form 56 when they assume responsibility for managing trust assets and related tax matters.
- Guardians and conservators
- Court-appointed guardians and conservators may also need to notify the IRS of their authority to act on behalf of another individual.
- Receivers and other court-appointed fiduciaries
- Receivers and assignees for the benefit of creditors may have additional filing obligations under the Internal Revenue Code.
Why would I file IRS Form 56 if I live abroad?
Americans abroad most commonly encounter Form 56 when serving as an executor, trustee, guardian, or another fiduciary with US tax responsibilities.
Although most expats never need Form 56, there are several realistic scenarios where it becomes relevant.
- Acting as executor of a parent’s estate from overseas
-
Imagine an American living in the United Kingdom whose parent passes away in the United States.
If they are appointed executor, they may need to:
- Notify the IRS of their appointment
- File final tax returns
- Respond to IRS correspondence
- Manage estate-related tax matters
-
- Serving as trustee of a trust
- Some Americans abroad serve as trustees for family trusts. In those situations, Form 56 may be used to notify the IRS that the trustee has assumed responsibility for tax administration.
- Acting as a guardian or conservator
- An expat who has been appointed to manage the affairs of an elderly parent or dependent relative may also encounter Form 56 requirements.
Note: Living abroad does not prevent you from serving as a fiduciary, but it can create logistical challenges such as mail delays, time zone differences, limited access to US courts, and difficulty obtaining documents. Planning ahead can help avoid complications.
What does IRS Form 56 actually do?
Form 56 does not create a fiduciary relationship. It notifies the IRS that the relationship already exists. Form 56:
- Allows the IRS to recognize your fiduciary authority: The IRS uses Form 56 to identify who is authorized to act regarding tax matters.
- Enables communication with the IRS: Once recognized, the fiduciary may be able to communicate with the IRS about the relevant tax matters, but Form 56 is not simply a request to receive copies of IRS notices.
- Establishes responsibility for certain tax matters: The fiduciary may be responsible for:
- Filing tax returns
- Paying taxes owed
- Responding to IRS inquiries
- Managing ongoing compliance obligations
What Form 56 does not do
Form 56 does not:
- Create fiduciary authority
- Serve as a power of attorney
- Change a taxpayer’s address
- Replace court appointment documents
When do I need to file IRS Form 56?
Form 56 should generally be filed when a fiduciary relationship begins or ends.
- After a taxpayer dies: Executors and personal representatives often file Form 56 after receiving legal authority to administer the estate.
- When a trust fiduciary is appointed: Trustees may file Form 56 when assuming responsibility for trust administration.
- When a court appoints a guardian or conservator: Court-appointed fiduciaries generally notify the IRS once their authority begins.
- When the fiduciary relationship ends: A second Form 56 may be filed to notify the IRS that the fiduciary relationship has terminated.
Filing timeline considerations
Most fiduciaries should file promptly after appointment. Receivers and assignees for the benefit of creditors have a more specific requirement and generally must provide notice within 10 days of appointment.
How do I complete IRS Form 56?
Form 56 requires information about the taxpayer, the fiduciary, and the fiduciary relationship.
Step 1: Identify the taxpayer: Provide the name, address, and taxpayer identification number of the individual or entity for whom you are acting.
Step 2: Identify the fiduciary: Provide your own identifying information and contact details.
Step 3: Describe the fiduciary relationship: Indicate whether you are acting as:
- Executor
- Trustee
- Guardian
- Conservator
- Receiver
- Other fiduciary
Step 4: Indicate whether the relationship began or ended: Specify whether you are notifying the IRS of the creation or termination of the fiduciary relationship.
Step 5: Sign and submit the form: Review the information carefully before signing and dating the form.
Where do I file Form 56?
Generally, Form 56 is mailed to the IRS service center where the taxpayer whose affairs you are managing is required to file tax returns.
Can Form 56 be filed electronically?
No. The IRS does not currently accept electronic filing of Form 56. The form must generally be printed, signed, and mailed.
Is IRS Form 56 the same as Form 2848?

What happens if I do not file IRS Form 56?
Failing to file Form 56 may make it more difficult for the IRS to recognize your authority to act on behalf of a taxpayer, estate, or trust.
- Potential communication issues: If Form 56 is not filed, the IRS may continue to recognize only the original taxpayer. Notices and requests may go to the wrong person, and the IRS may refuse to discuss the account due to privacy rules.
- Delays in handling tax matters: Without Form 56, fiduciaries may face delays accessing information or resolving issues, especially if additional documentation is required.
- Estate and trust administration complications: Not notifying the IRS can complicate estate or trust administration. While there is no specific penalty for not filing Form 56, fiduciaries must still meet all tax obligations or risk penalties and interest.
Is there a specific penalty for not filing Form 56?
There is no widely cited standalone penalty specifically tied to failing to file Form 56. However, failing to establish your role with the IRS can complicate tax administration and delay important actions.
Frequently Asked Questions
Can I attach supporting documents to IRS Form 56?
Yes. Depending on the situation, fiduciaries may attach documents that establish their authority, such as court appointment papers, letters testamentary, trust documents, or other legal records. Providing supporting documentation can help the IRS verify the fiduciary relationship.
Does filing Form 56 make me personally liable for someone else’s taxes?
Not automatically. Filing Form 56 notifies the IRS of a fiduciary relationship. However, fiduciaries may have legal responsibilities to manage tax matters properly. Personal liability generally depends on the facts and circumstances, including whether the fiduciary properly fulfills their duties.
Can an executor living outside the United States file Form 56?
Yes. US citizens and residents living abroad can serve as executors, trustees, guardians, and other fiduciaries. Living outside the United States does not prevent someone from filing Form 56 when they have legal authority to act.
Should Form 56 be filed before or after filing a tax return?
In many cases, fiduciaries file Form 56 soon after their appointment and before handling significant tax matters. Filing early can help establish authority with the IRS before submitting returns, requesting information, or responding to notices.
Does Form 56 expire?
Form 56 does not have a specific expiration date. The fiduciary relationship generally remains in effect until it ends under the governing legal documents, court order, or applicable law. When the relationship ends, the IRS should generally be notified.
Can multiple executors or co-trustees be listed with the IRS?
Yes. If there is more than one fiduciary, each fiduciary should generally file a separate Form 56 or otherwise provide notice of their fiduciary status to the IRS.
What records should I keep after filing Form 56?
Fiduciaries should generally keep:
- A copy of the completed Form 56
- Proof of mailing or delivery
- Court appointment documents
- Trust agreements, if applicable
- Correspondence received from the IRS
Maintaining complete records can help resolve questions later in the administration process.
What should I do if I discover the fiduciary relationship years later?
If you recently became aware of a fiduciary obligation that should have been reported, consider filing Form 56 as soon as practical and reviewing whether any tax returns or notices require attention. In complex situations, professional advice may be helpful.
Does Form 56 apply to foreign trusts?
Sometimes. Whether Form 56 is required depends on the fiduciary relationship and the trust’s connection to US tax obligations. Trustees of foreign trusts with US reporting requirements may need to consider Form 56 alongside other trust-related filings.
Can I correct a mistake on a previously filed Form 56?
Yes. If information changes or an error is discovered, fiduciaries can generally notify the IRS by submitting updated information and, when appropriate, a new Form 56 reflecting the correct details.
