IRS Instruction 56 – In the complex world of tax administration, managing fiduciary relationships requires precise documentation to ensure compliance with IRS regulations. IRS Form 56, officially titled “Notice Concerning Fiduciary Relationship,” plays a crucial role in notifying the IRS about the creation or termination of such relationships. Whether you’re an executor handling a decedent’s estate, a trustee overseeing a trust, or a guardian managing assets, understanding the instructions for Form 56 is essential to avoid penalties and streamline tax processes. This guide, based on the latest IRS updates as of 2026, breaks down everything you need to know about Form 56 instructions, including purpose, filing requirements, and step-by-step completion tips.
What Is IRS Form 56 and Its Purpose?
IRS Form 56 is a notification form used under Internal Revenue Code sections 6903 and 6036. Its primary purpose is to inform the IRS of the establishment or termination of a fiduciary relationship, where one party (the fiduciary) acts on behalf of another (the principal) in tax matters. This allows the fiduciary to handle tax responsibilities, such as filing returns and paying taxes, as if they were the taxpayer themselves.
Key purposes include:
- Notifying the IRS when a fiduciary assumes control over assets, such as in estates, trusts, or bankruptcies.
- Providing notice of qualification for receivers or assignees for the benefit of creditors.
- Revoking or terminating prior fiduciary notices when the relationship ends.
Important note: Form 56 does not update addresses—use Form 8822 or 8822-B for that. It’s also distinct from Form 2848 (Power of Attorney), which authorizes representatives but doesn’t establish fiduciary status.
Fiduciary relationships often arise in scenarios like probate, guardianship, or asset assignments, ensuring the IRS directs correspondence and liabilities correctly. Filing this form voluntarily complies with tax laws but is required in specific situations to avoid processing delays.
Who Must File Form 56?
Not everyone involved in asset management needs to file Form 56. The form is mandatory for fiduciaries who:
- Seek to act on behalf of a taxpayer before the IRS under section 6903.
- Are receivers or assignees for the benefit of creditors giving notice under section 6036.
Examples of who must file:
- Executors or administrators of estates (testate or intestate).
- Trustees of valid trusts.
- Guardians or conservators appointed by courts.
- Receivers in non-bankruptcy proceedings or assignees for creditors.
Exemptions:
- Bankruptcy trustees or debtors-in-possession follow Bankruptcy Rules instead.
- Authorized representatives should use Form 2848.
- If multiple fiduciaries exist, each must file separately, even if acting for the same entity.
For decedents’ estates, file one form for the decedent and another for the estate if needed. This ensures clear separation of tax liabilities.
When and Where to File IRS Form 56?
Timing is critical for Form 56 compliance. File the form promptly upon the creation or termination of the fiduciary relationship.
When to File?
- Creation: Submit as soon as the fiduciary role begins, such as after court appointment or asset transfer.
- Termination: File when the relationship ends, like upon estate distribution or trust dissolution.
- Specific deadlines: Receivers and assignees must file within 10 days of appointment with the appropriate IRS Advisory Group Manager.
No fixed annual deadline exists, but delays can lead to penalties or suspended processing.
Where to File?
- General cases: Send to the IRS Service Center where the principal (e.g., decedent or entity) files tax returns.
- Special proceedings (non-bankruptcy receiverships or assignments): File with the Advisory Group Manager in the IRS area office with jurisdiction. Refer to IRS Publication 4235 for contact details.
Electronic filing isn’t available for Form 56; mail it physically. For the latest filing addresses, check the IRS website.

Key Definitions in Form 56 Instructions
Understanding terminology is key to accurate filing:
- Fiduciary: Anyone acting in confidence for another, including executors, trustees, guardians, and receivers.

- Decedent’s Estate: A separate taxable entity from death until final distribution.
