What is Form 56?
Form 56, officially titled Notice Concerning Fiduciary Relationship, is used to notify the IRS when a person or entity becomes responsible for another taxpayer’s tax matters. This applies when a fiduciary, such as a guardian, executor, administrator, or trustee, is appointed to act on behalf of an individual, estate, or trust.
By filing this form, the IRS is formally informed of who is authorized to receive tax notices, respond to IRS communications, and handle the taxpayer's tax obligations. This helps prevent delays, misdirected correspondence, and confusion about who is responsible for IRS matters.
What is Form 56 used for?
Form 56 is used to notify the IRS about fiduciary relationships for tax purposes formally. Specifically, it is used to:
- Notify the IRS of the creation or termination of a fiduciary relationship under section 6903.
- Provide notice of fiduciary qualification under section 6036 when required.
- Identify the fiduciary’s name, authority, and contact information for IRS records.
- Enable the IRS to communicate directly with the fiduciary regarding tax matters related to an estate, trust, or individual.

Who is required to fill out Form 56?
Fiduciaries, including those acting on behalf of individuals, estates, or trusts, are responsible for completing Form 56. Receivers and assignees also use this form for creditors.
After completion, the Internal Revenue Service uses Form 56 to track changes in fiduciary status, which can affect tax obligations and reporting requirements by determining who is authorized to receive IRS notices and handle tax matters on behalf of the taxpayer.
When is Form 56 not required?
Form 56 is not necessary if there is no change in the fiduciary relationship, and the fiduciary relationship has already been reported to the IRS. Additionally, individuals without legal responsibility for managing an estate, trust, or another person’s tax matters do not need to file Form 56.
When is Form 56 due?
