IRS Form 56 for Expats Explained: Fiduciary Notice to the IRS
IRS Form 56, officially titled “Notice Concerning Fiduciary Relationship,” is the form you file to tell the IRS that you are legally responsible for someone else’s tax affairs. If you’ve been appointed executor of an estate, trustee of a trust, guardian of a minor or incapacitated person, or receiver in a legal proceeding, Form 56 establishes your authority so the IRS sends all tax correspondence directly to you.
According to the IRS instructions for Form 56, once you file this form, the IRS treats you as if you are the taxpayer, with full authority to file returns, make payments, and respond to notices on their behalf.
For American expats, the form itself is straightforward, but managing fiduciary duties from abroad adds logistical challenges: coordinating across time zones, handling mail internationally, and potentially dealing with foreign assets in the estate or trust. These are solvable, and this guide covers what you need to know.
Not Sure If You Need to File Form 56?
For line-by-line instructions on completing Form 56, see our step-by-step guide.
Who Needs to File Form 56?
| Fiduciary Role | When to File | Typical Scenario |
|---|---|---|
| Executor or administrator (estate) | When appointed by the court after someone dies | A parent passes away and names you executor in their will |
| Trustee | When you assume management of trust assets | Your family creates a trust and appoints you to manage it |
| Guardian or conservator | When a court appoints you to manage someone’s finances | A court appoints you to handle finances for an aging parent |
| Receiver | Within 10 days of the appointment | A court appoints you in a receivership proceeding |
| Assignee for the benefit of creditors | Within 10 days of the appointment | You’re assigned to manage assets in a creditor arrangement |
Who Does NOT Need Form 56?
| Situation | What to File Instead |
|---|---|
| You’re someone’s authorized tax representative (e.g., a CPA filing on their behalf) | Form 2848 (Power of Attorney) |
| You’re a fiduciary for a financial institution (bank, thrift) | Form 56-F |
| You’re a bankruptcy trustee | Separate notice requirements under Title 11 of the U.S. Code |
The distinction between Form 56 and Form 2848 is the most common point of confusion. Form 56 is for fiduciaries who have legal authority over someone’s tax affairs (you are the taxpayer in the IRS’s eyes). Form 2848 is for representatives who act on someone’s behalf but don’t assume their legal identity.
When Do I File Form 56?
- At the start of the relationship: File Form 56 as soon as you are appointed or assume your fiduciary role. There is no specific deadline for most fiduciary types, but filing promptly ensures the IRS directs correspondence to you rather than to an address that may no longer be monitored.
- Receivers and assignees: Must file within 10 days of appointment with the Advisory Group Manager of the appropriate IRS area office.
- With a tax return: Form 56 is often attached to the first tax return you file in your fiduciary capacity (estate return, trust return, or individual return for the person you’re managing).
- At the end of the relationship: File Form 56 again (Part II) to notify the IRS that the fiduciary relationship has terminated. This is critical. If you don’t file the termination notice, the IRS will continue sending correspondence to you indefinitely.
How Do I File Form 56?
Form 56 cannot be filed electronically. You must print, sign, and mail it to the IRS service center where the person you’re representing normally files their tax returns.
What to Include When Filing
- Completed Form 56 (signed and dated)
- Evidence of your authority (court appointment letter, trust document, letters testamentary)
- The taxpayer’s identifying information (name, SSN or EIN, address)
Form 56 cannot be used to change the taxpayer’s address. If you need to update their address, file Form 8822 (Change of Address) separately.
What Does Form 56 Cover?
When you complete Form 56, you specify the scope of your authority:
- Section A (Authority): Check the box that describes your role (executor, trustee, guardian, receiver, or other). Enter the date of death (for estates) or date of appointment (for other roles).
- Section B (Tax Types): Check which types of taxes you’ll handle (income, estate, gift, employment, excise, etc.) and specify the form numbers and tax years or periods.
- Part II (Termination): Used only when the fiduciary relationship ends. Check the box to revoke all prior notices and indicate the reason (court order, completion of duties, replacement by another fiduciary).

Expat-Specific Considerations
Filing from Abroad
Living overseas doesn’t change the Form 56 requirements, but it affects logistics:
- Mailing: Use an international express mail service with tracking for your initial filing. Standard international mail can take weeks, and you need a delivery confirmation.
- Time zones: If you need to contact the IRS by phone about your filing, account for the time difference. IRS phone lines operate on Eastern Time.
- Deadlines: American expats get an automatic two-month extension for filing tax returns (to June 15), which applies to returns you file in your fiduciary capacity as well. See our guide on expat tax deadlines.
Managing a U.S. Estate from Abroad
If a family member in the U.S. passes away and names you executor while you’re living overseas, you’ll need to:
- Obtain court appointment (which may require appearing in person or through a U.S.-based attorney)
- File Form 56 to establish your authority with the IRS
- File the decedent’s final Form 1040 for income earned in the year of death
- File Form 1041 (estate income tax return) if the estate generates income
- File Form 706 (estate tax return) if the estate exceeds the filing threshold ($13.99 million for 2025)
- File FBAR if the decedent held foreign accounts exceeding $10,000
Serving as Trustee from Abroad
If you’re appointed trustee of a U.S. trust while living abroad, your filing obligations include Form 56 plus annual Form 1041 filings. If the trust holds foreign assets or has foreign beneficiaries, additional reporting requirements may apply, including Form 3520-A for foreign trusts.

Your Own Fiduciary Tax Obligations
Form 56 relates to the other person’s tax affairs, not yours. Your personal expat tax obligations (filing your own Form 1040, claiming the FEIE or Foreign Tax Credit, FBAR reporting) remain separate and unchanged by your fiduciary role.
Common Mistakes to Avoid
- Not filing the termination notice. When your fiduciary duties end, file Part II of Form 56. Without it, the IRS continues treating you as the responsible party and sending correspondence to you.
- Confusing Form 56 with Form 2848. Form 56 is for fiduciaries with legal authority. Form 2848 is for representatives (like your CPA). Filing the wrong form delays your ability to act.
- Missing the 10-day deadline for receivers and assignees. Other fiduciary types don’t have a strict deadline, but receivers and assignees must file within 10 days.
- Not specifying the correct tax types and periods. If you only check “income tax,” but the estate also owes employment taxes, the IRS won’t direct employment tax notices to you.
- Trying to e-file. Form 56 must be mailed. There is no electronic filing option.
Frequently Asked Questions
No. Form 56 must be printed, signed, and mailed to the IRS service center where the taxpayer you’re representing files their returns. Use tracked mail, especially if filing from abroad.
Form 56 establishes a fiduciary relationship: the IRS treats you as the taxpayer. Form 2848 (Power of Attorney) authorizes a representative to act on someone’s behalf without assuming their legal identity. Executors, trustees, and guardians use Form 56. CPAs and attorneys typically use Form 2848.
Not until you are officially appointed by the court. Being named in a will does not create a fiduciary relationship. File Form 56 after you receive your court appointment (letters testamentary or letters of administration).
Complete Part II of Form 56, check the box to revoke all prior notices, indicate the reason for termination, and mail it to the same IRS service center where you filed the original Form 56.
No. Form 56 concerns the other person’s tax affairs. Your personal expat tax obligations remain separate. You’ll file your own Form 1040 as usual, and any returns you file in your fiduciary capacity are separate filings.
Yes. Living overseas doesn’t disqualify you from serving as executor, trustee, or guardian. The logistical challenges (international mail, time zones, potential in-person court appearances) are manageable with proper planning and, often, a U.S.-based attorney who can handle local proceedings.
