Executor and Fiduciary Authority With the IRS: Form 56, POA and Account Access

An executor calls the IRS about a deceased taxpayer. The IRS will not discuss the account.

The instinct may be: “I need a power of attorney.” Maybe. But first comes a different question: has the executor's own fiduciary authority been established with the IRS? Form 56 and Form 2848 do different jobs.

Form 56 addresses fiduciary capacity.

IRC §6903 provides the federal framework for notifying the IRS that a person is acting in a fiduciary capacity. Form 56 is used for that purpose under the applicable instructions. Think: “I am the person legally acting in this taxpayer's or entity's place.”

Form 2848 is representation authority.

Form 2848 authorizes an eligible representative to act before the IRS for specified matters and periods. Think: “I have authority, and I am authorizing this professional to represent the matter.”

The fiduciary can appoint a representative.

The sequence can therefore be: fiduciary authority → Form 56 → representative appointment → Form 2848. Do not make the professional's POA substitute for establishing the executor's underlying capacity where fiduciary recognition is required.

Start with the court and estate documents.

Reconstruct the death certificate, Letters Testamentary or Letters of Administration, court appointment, estate EIN where applicable, decedent's SSN, tax periods involved, IRS notices, prior Forms 56 and existing powers of attorney.

Form 56 should match the capacity.

Determine whether the fiduciary is acting for the deceased individual, the estate, or another taxpayer/entity relationship. Follow the capacity actually created by law and the current Form 56 instructions.

Form 56 does not change the last known address by itself.

The current instructions distinguish fiduciary notice from changing a taxpayer's last known address. Use the appropriate IRS address-change procedure, such as Form 8822 where applicable.

Establishing authority does not extend another deadline.

If the estate or decedent has a Notice of Deficiency, examination request, refund deadline, collection notice or another time-sensitive document, the substantive deadline continues to matter. Protect it while authority paperwork is processed.

Fiduciary authority and personal liability are different.

Filing Form 56 does not automatically make the executor personally liable for the decedent's tax. Whether separate fiduciary exposure exists depends on different facts and authority.

Form 56 does not remove tax, penalties, interest or liens.

It is an authority/capacity document. Once authority is established, the underlying tax problem still needs its own procedural response.

Requesting records is a separate operational step.

A recognized fiduciary may need transcripts, prior returns, notices or account information. Follow current deceased-person information-request procedures and provide the required proof of authority.

Existing POAs deserve review after death.

A power of attorney created during life and fiduciary authority after death are not automatically the same thing. Review whether an existing authorization remains usable and whether a new Form 2848 is appropriate.

Form 8821 is different again.

Form 8821 generally authorizes access to specified tax information. It does not provide the same representation authority as Form 2848.

Refund and property matters add separate procedures.

Form 1310 may separately be required for a refund claim. If estate property may be subject to a federal tax lien, fiduciary authority is only the starting point; property rights and lien remedies require their own analysis.

A practical fiduciary-authority sequence.

1. Identify who was legally appointed.
2. Gather court and death documentation.
3. Identify the taxpayer/entity and tax periods.
4. File Form 56 where appropriate.
5. Address the last known address separately where required.
6. Request necessary records.
7. Execute Form 2848 separately if professional representation is needed.
8. Protect every substantive deadline.
9. Use the appropriate additional procedure for refunds, collection, liens or amended returns.

The PRISM principle

Form 56 answers “Who legally stands in the taxpayer's place?” Form 2848 answers “Who is authorized to represent that person before the IRS?”
