IRS Form 56: Notice Concerning Fiduciary Relationship. This form is important when someone is legally acting on behalf of another taxpayer—for example, an executor handling a deceased person’s tax matters or a trustee managing a trust. The IRS explains that Form 56 notifies the agency when a fiduciary relationship begins or ends, and it has specific filing rules.

What Is IRS Form 56?

When someone manages another person’s financial affairs, handles an estate after a death, or acts as a trustee, there may be additional tax responsibilities to consider. One important document is IRS Form 56, Notice Concerning Fiduciary Relationship.

Form 56 is used to notify the Internal Revenue Service (IRS) that a fiduciary relationship has been created or terminated. In simple terms, it tells the IRS that someone has legal authority to act in a fiduciary capacity for another taxpayer or entity.

For individuals and families in Grand Rapids, Kentwood, Wyoming, and throughout West Michigan, understanding Form 56 can help when managing an estate, administering a trust, or handling certain financial and tax matters for someone else.

AIM Financial helps taxpayers understand tax forms and filing responsibilities so they can better prepare for tax season and address important reporting requirements.

What Does “Fiduciary” Mean?

A fiduciary is a person or entity that acts in a position of trust on behalf of another person or organization. A fiduciary generally has responsibilities to act within the authority granted and in the interests of the person or entity being represented.

Examples of fiduciaries may include:

• Executors and estate administrators: People responsible for managing a deceased person’s estate.
• Trustees: Individuals responsible for managing assets held in a trust.
• Guardians and conservators: Individuals authorized to manage certain personal or financial matters for another person.
• Receivers: Individuals appointed to take control of property or assets in certain legal proceedings.
• Certain bankruptcy fiduciaries: Individuals acting in roles recognized under applicable law.

The exact responsibilities depend on the legal arrangement, court appointment, or other authority involved.

When Is Form 56 Used?

The IRS uses Form 56 to receive notice of the creation or termination of a fiduciary relationship under Internal Revenue Code Section 6903. The form can also provide notice of qualification in certain circumstances under Section 6036.

For example, suppose a person passes away and an executor is appointed to administer the estate. The executor may need to notify the IRS of the fiduciary relationship so the agency has notice of the executor’s role.

Another example involves a trustee who manages a trust and must communicate with the IRS in a fiduciary capacity. Form 56 may be appropriate when the relationship begins or ends.

Form 56 does not create legal authority by itself. The authority must come from the applicable will, trust, court appointment, or other legal basis.

Who Should File Form 56?

A fiduciary who needs to notify the IRS of the creation or termination of a fiduciary relationship generally files Form 56. Receivers and certain assignees for the benefit of creditors also use the form to provide notice of qualification in applicable proceedings.

The form may be relevant to estate administration, trust management, and other situations where a person is acting in a recognized fiduciary role.

Not every person helping a relative with financial matters automatically qualifies as a fiduciary for IRS purposes. The person’s authority and the nature of the relationship must be evaluated under the applicable rules.

If you are unsure whether Form 56 is required, review the current IRS instructions or seek qualified tax or legal guidance.

What Information Is Needed to Complete Form 56?

Form 56 asks for information identifying the taxpayer or entity and the person serving as fiduciary. Depending on the circumstances, the form generally requires information such as:

• The name and taxpayer identification number of the person or entity represented.
• The address of the person or entity.
• The fiduciary’s name, address, and contact information.
• The type and legal basis of the fiduciary relationship.
• Information about the creation or termination of the relationship.
• The relevant dates and other details requested by the form.

The information should be consistent with the relevant legal documents and tax records. For an estate, for example, the executor may need information from the deceased person’s records and documentation showing the appointment.

Keep a copy of the completed form and supporting records for your files.

When and Where Should Form 56 Be Filed?

Generally, Form 56 should be filed when the fiduciary relationship is created or terminated. The filing location depends on the circumstances.

For many situations, the form is sent to the IRS service center where the person or entity being represented is required to file tax returns. Special rules and filing addresses apply to certain receivers and assignees for the benefit of creditors.

Because the IRS can update its forms and mailing instructions, check the latest Instructions for Form 56 before mailing the form.

It is also important to distinguish Form 56 from other IRS documents. Form 56 is not a substitute for an estate’s or trust’s required income tax returns, and filing it does not automatically satisfy all tax obligations.

Form 56 vs. Form 2848: What Is the Difference?

Form 56 and Form 2848 serve different purposes.

IRS form	Main purpose
Form 56	Notifies the IRS of the creation or termination of a fiduciary relationship and provides certain required notices.
Form 2848	Authorizes an eligible individual to represent a taxpayer before the IRS within the authority granted.

A fiduciary relationship and an authorization to represent someone before the IRS are not necessarily the same thing. The correct form depends on the legal role and the action being taken.

Form 56 also cannot be used simply to change the address of the taxpayer or entity being represented. The IRS identifies Form 8822 or Form 8822-B as the appropriate forms for certain address changes.

Common Mistakes to Avoid

When handling Form 56, taxpayers and fiduciaries should avoid these common mistakes:

• Assuming the form replaces an estate or trust income tax return.
• Using Form 56 to change a taxpayer’s mailing address.
• Providing incomplete or inconsistent identifying information.
• Failing to notify the IRS when a reportable fiduciary relationship ends.
• Assuming Form 56 automatically grants legal authority that has not otherwise been established.
• Using Form 56 when a different authorization or notification is appropriate.

Careful preparation can help reduce confusion when dealing with an estate, trust, or another person’s tax matters.
