IRS Form 56 Filing Requirements
IRS Form 56, the Notice Concerning Fiduciary Relationship, tells the IRS who is now responsible for another person's tax matters. It is filed by executors, administrators, trustees, guardians, conservators, receivers, and assignees under Internal Revenue Code sections 6903 and 6036. Below is everything you need to know: who files, when, what to attach, and how the paper filing actually works.
File Your Form 56Who Files Form 56
- A parent died and you are the executor. You will handle their final tax return and deal with any IRS letters: Form 56 puts you on record as the person the IRS should write to
- You are the administrator of an estate with no will. Same notice, with your court certificate of appointment attached
- You are the trustee of a family trust. Form 56 covers the trust's tax matters, with your authority under the trust instrument
- A court appointed you guardian or conservator for a minor or an adult who cannot manage their own affairs
- You are a receiver or an assignee for the benefit of creditors. You are required to notify the IRS within 10 days of appointment, with the court details of the proceeding
Key point: a separate Form 56 is required for each person or entity you act for. An executor who files the decedent's final Form 1040 and also administers the estate files two notices: one under the decedent's SSN and one under the estate's EIN.
Who does not use Form 56: representatives acting under a power of attorney use Form 2848 instead, and bankruptcy trustees are exempt from the section 6036 notice of qualification.
When to File
- On appointment: file when your fiduciary role begins. The IRS instructions direct a fiduciary who seeks to act on someone's behalf to give this notice
- Receivers and assignees: within 10 days of appointment (26 CFR 301.6036-1)
- When the role ends: a second Form 56 (Part II) terminates the notice so IRS correspondence stops coming to you
There is no monetary penalty for filing late or not at all. The reason to file promptly is practical: until the notice is on file, the IRS validly sends every letter about the person you represent, including statutory notices of deficiency, to their last known address, and deadlines can pass without you seeing them.
Requirements by Role
| Role | When to File | What to Attach | Special Notes |
|---|---|---|---|
| Executor / personal representative | On court appointment | Current letters testamentary or a court certificate | Two forms if also administering the estate (decedent SSN + estate EIN) |
| Administrator (no will) | On court appointment | Court certificate of appointment | Same two-filings rule when administering the estate |
| Trustee | When trust responsibility begins | Evidence of authority under the trust instrument | Uses the trust's EIN |
| Guardian / conservator | On court appointment | Court certificate of appointment | Uses the individual's SSN or ITIN |
| Receiver | Within 10 days of appointment | Court details (Part III): court, address, docket number | Answers line 2c (assets in the court's custody); mails to the IRS Insolvency address in Dallas, TX |
| Assignee for creditors | Within 10 days of appointment | Court/proceeding details (Part III), a description of the assigned assets, and the action to be taken with them | Mails to the IRS Insolvency address in Dallas, TX |
Evidence of authority matters: the Form 56 instructions require court-appointed executors and administrators to attach current letters testamentary or a court certificate, and every fiduciary must be prepared to furnish evidence that substantiates their authority.
What the Form Covers
Section B of Form 56 states which federal tax matters the notice applies to: which forms (1040, 1041, 706, 709, employment tax returns, and so on) and which years or periods. The information the form asks for:
Our default recommendation: cover all tax matters and periods unless you have a specific reason to narrow the notice. A narrow notice can leave correspondence about other forms or years going to the old address.
How Filing Works
Paper Only, Signed Personally
There is no e-file option for Form 56. The completed form is mailed to the IRS service center where the person you act for is required to file returns; the correct address depends on their return type and state.
- The fiduciary signs personally, with title and date, under penalty of perjury.
- A preparer cannot sign in the fiduciary's place.
- Receivers/assignees mail to: Internal Revenue Service, Insolvency, MS 5027 DAL, Dallas, TX 75242.
Proof of Filing
The IRS does not send an acknowledgment for Form 56 and only corresponds if required information or evidence is missing. Do not wait for a confirmation that will never come. Your mailing record is your proof, which is why we send every filing by USPS Certified Mail and give you the tracking number plus a copy of the form exactly as mailed.
What Form 56 Is Not
- Not a power of attorney. Appointing an attorney, CPA, or agent to represent a taxpayer is done with Form 2848
- Not a change of address. A taxpayer's address is changed with Form 8822 (or 8822-B for businesses)
- Not a discharge from personal liability. A fiduciary requesting discharge from personal liability for a decedent's taxes uses Form 5495. Filing Form 56 neither creates nor discharges fiduciary liability; for questions about personal liability, consult an attorney
Common Questions
Someone died and I'm handling everything. Is Form 56 really my job?
If you are the executor, administrator, or personal representative, yes. Form 56 puts you on record with the IRS so correspondence about the deceased person's tax matters comes to you instead of going to their old address. If you will also administer the estate, a second Form 56 is filed for the estate under its own EIN.
Is there a deadline?
For most fiduciaries there is no statutory deadline; the IRS instructions direct a fiduciary who seeks to act to give the notice, so the practical answer is to file when your role begins. The exception is receivers and assignees for the benefit of creditors, who are required to file within 10 days of appointment.
Can I e-file Form 56?
No. Form 56 is paper only. It is mailed to the IRS service center where the person you act for is required to file returns, which depends on their return type and state. Receivers and assignees mail to the IRS Insolvency unit in Dallas, TX.
Can someone sign the form for me?
No. The fiduciary signs Form 56 personally, with their title and the date, under penalty of perjury. A preparer cannot sign in the fiduciary's place. We prepare the form; you sign it; we mail it.
Will the IRS confirm receipt?
No. The IRS does not send an acknowledgment for Form 56 and only writes back if required information or evidence is missing. Your proof of filing is the mailing record, which is why we use USPS Certified Mail and send you the tracking number and a copy of the form as mailed.
What happens when my role ends?
A second Form 56, completing Part II, terminates the notice so IRS mail stops coming to you. The reason (court order, dissolution, or resignation/discharge) is indicated on the form. A new or substitute fiduciary files their own Form 56.
Ready to File?
