What IRS Form 56 Is and Why It Matters

IRS Form 56, officially called "Notice of Fiduciary Relationship," is a document that tells the Internal Revenue Service about a change in who is legally responsible for handling tax matters. This form is used when someone other than the original taxpayer needs to take over tax duties—such as a guardian, executor, trustee, or power of attorney holder.

The form serves a specific purpose: it notifies the IRS that a fiduciary relationship exists. A fiduciary is a person or organization that has a legal duty to act in someone else's best interest regarding financial or tax matters. When someone becomes a fiduciary, they often need to inform the IRS so that tax documents, notices, and correspondence go to the right person.

Common situations where Form 56 becomes relevant include:

• An executor managing a deceased person's estate and needing to handle final tax returns
• A guardian appointed for a minor child or incapacitated adult
• A trustee managing a trust's tax obligations
• An attorney-in-fact acting under a power of attorney document
• A conservator managing financial affairs for someone unable to do so themselves

Understanding what this form does helps people recognize when they might need to file it. The IRS information guide about Form 56 explains these situations in detail, showing readers which circumstances require notification and which do not. This distinction matters because submitting the form when not necessary could create confusion, while failing to submit it when required might result in important tax documents being sent to the wrong person.

Takeaway: Learn whether your situation involves a fiduciary relationship that the IRS needs to know about by reviewing what the form covers and which life circumstances typically trigger the need for notification.

The Different Types of Fiduciary Relationships

Not all fiduciary relationships are the same. The IRS recognizes several distinct types, and the form works differently depending on which category applies. Understanding these categories helps people determine whether they actually need to file Form 56 or whether their situation doesn't require IRS notification.

An executor or administrator handles the estate of someone who has died. They manage the deceased person's assets, pay debts and taxes, and distribute what remains to heirs. An executor is typically named in a will, while an administrator is appointed by a court when no will exists. Both roles make someone a fiduciary who may need to notify the IRS.

A guardian or conservator is appointed by a court to make decisions for someone who cannot make decisions themselves. Guardians often handle personal care decisions, while conservators typically manage financial matters. A parent is not usually considered a fiduciary for their minor child's tax purposes, but a court-appointed guardian for an adult child would be. This distinction is important because it affects whether Form 56 is required.

A trustee manages property held in a trust. Trusts are created during someone's lifetime or through their will and serve various purposes—protecting assets, managing money for beneficiaries, or planning for incapacity. A trustee's fiduciary duties regarding taxes may require Form 56 notification depending on the trust's structure and the types of tax obligations involved.

An attorney-in-fact or agent under a power of attorney holds legal authority to act on someone else's behalf. This might include managing taxes, but not all powers of attorney involve tax matters. Someone might have authority to make healthcare decisions but not financial ones, or vice versa. The scope of the power of attorney determines whether Form 56 is necessary.

A representative payee receives Social Security or other benefits on behalf of a beneficiary who cannot manage the money themselves. Representative payees are not always considered fiduciaries for tax purposes, which is why the IRS guide specifically clarifies when Form 56 does and does not apply to representative payees.

Takeaway: Identify which category of fiduciary relationship (if any) applies to your situation by learning about the specific roles and how the IRS distinguishes between them.

When You Must File Form 56 and When You Don't

The IRS Form 56 information guide provides clear guidance about which situations require filing and which do not. This distinction prevents unnecessary filings and ensures that people who actually need to notify the IRS do so correctly.

Form 56 is generally required when a fiduciary has taken control of tax matters and needs the IRS to send future tax documents, notices, and correspondence to them instead of the original taxpayer. For example, an executor settling a deceased person's final tax return would typically file Form 56 so the IRS directs all related correspondence to the executor's address.

Form 56 is typically required in these situations:

• An executor or administrator managing a deceased person's estate and tax returns
• A court-appointed guardian handling tax matters for an adult ward
• A trustee of a trust that has its own tax identification number and files its own returns
• Someone acting under power of attorney who needs the IRS to recognize their authority to receive documents and make changes
• A conservator appointed by a court to manage financial and tax matters

Form 56 is generally not required in these situations:

• A parent handling a minor child's taxes (parents have automatic authority for minor children)
• A representative payee who only manages benefits, not other income or taxes
• Someone with limited power of attorney authority that doesn't include tax matters
• Informal family arrangements where no court appointment or legal document establishes fiduciary duty
• A spouse managing joint tax returns (no separate fiduciary relationship exists)

The IRS guide explains the reasoning behind these distinctions. Parents don't need Form 56 for their minor children because the tax system assumes parental authority. Representative payees managing only benefits don't need it because their role doesn't extend to full tax authority. These exceptions prevent unnecessary paperwork while ensuring required notifications reach the IRS.

Takeaway: Review the specific criteria in the form's information guide to determine whether your fiduciary situation requires notification or falls into a category where filing is unnecessary.

How to Complete and File Form 56

The IRS Form 56 information guide walks through the completion process step by step. The form itself is relatively straightforward, but accuracy matters because it establishes the IRS's recognition of the fiduciary relationship.

The form contains several key sections. The first section requires identifying the taxpayer—the person whose tax matters are being managed. This includes their name, Social Security number or tax identification number, and current address. Accuracy here is critical because the IRS uses this information to locate the correct tax account.

The second section identifies the fiduciary—the person filing the form and taking over responsibility. This includes the fiduciary's name, address, phone number, and relationship to the taxpayer (executor, guardian, trustee, etc.). This section establishes who the IRS should contact and send documents to in the future.

The form asks for the date the fiduciary relationship began. This helps the IRS understand when the change in authority took effect. For an executor, this might be the date of death. For a court-appointed guardian, it's typically the date the court order was issued. For a trustee, it might be the date the trust became effective or the date the person assumed trustee duties.

The form includes checkboxes for the type of fiduciary relationship. The filer checks the box that matches their role: executor/administrator, guardian/conservator, trustee, power of attorney, representative payee, or other. This helps the IRS understand the legal basis for the authority being claimed.

Form 56 requires supporting documentation. The guide explains what documents to attach: a copy of the court order for court-appointed roles, a copy of the trust document for trustees, a copy of the power of attorney for agents, proof of death for executors, or other documentation establishing the fiduciary relationship. The IRS must be able to verify the authority being claimed.

The form is mailed to the IRS address specified in the instructions, which may vary depending on whether the taxpayer is an individual
