Why Does an Estate Need Its Own EIN?
The estate is a separate legal entity from the person who died. It earns income, pays debts, and holds a bank account, and every one of those actions runs through the estate's own 9-digit EIN, not the deceased's SSN.
| Task | Needs the estate EIN? | Detail |
|---|---|---|
| Open the estate bank account | Yes | Banks require the 9-digit EIN, not the deceased's SSN |
| File the Form 1041 income return | Yes | Required at $600 of gross income |
| Collect interest, rent, or dividends | Yes | Income earned after death is reported under the EIN |
| Pay estate expenses and debts | Yes | The executor writes checks from the 1 estate account |
| File the Form 706 estate tax return | Only above the exemption | Applies above $13.99 million in 2025 |

The estate account keeps the deceased's money separate from the executor's own funds, which the probate court requires. A bank opens that account only against the estate's EIN and the letters testamentary from the court. The EIN is a Federal Employer Identification Number, the same identifier covered on what is a FEIN.
The estate account is titled "Estate of [name], [executor] executor," and every dividend, interest payment, and rent check dated after the day of death is deposited into that 1 account under the estate EIN. Mixing those funds with the deceased's old personal accounts, still tied to a Social Security Number that closed at death, exposes the executor to personal liability before the probate court. Reporting the estate's income correctly begins with the estate EIN, the number covered on using your EIN.
No SSN. No passport upload.
Who Is the Responsible Party for an Estate EIN?
The executor, administrator, or personal representative is the responsible party. That person signs Form SS-4 and enters their own name on line 7a and their own SSN or ITIN on line 7b. Only 1 responsible party is named per estate.
The probate court appoints the executor, most often the one named in the will, and issues letters testamentary that prove the appointment. That executor is the individual the IRS holds accountable for the estate's filings under 26 U.S.C. section 6109. The responsible party is a person, never a company, so the executor uses their personal identifier on line 7b, not the estate's EIN. The mechanics of naming the responsible party and completing Form SS-4 sit on how to get an EIN.
When no will names an executor, the probate court appoints an administrator, who becomes the responsible party the same way and enters their own SSN or ITIN on line 7b of Form SS-4. A bank, a co-heir, or an attorney is never the responsible party for an estate, because 26 U.S.C. section 6109 ties the number to 1 individual with a personal taxpayer ID. If that individual later loses the CP-575 confirmation letter, the IRS reissues the estate EIN on a 147C letter, free, at 800-829-4933. The full walkthrough of naming the responsible party sits on how to get an EIN, and recovering a misplaced number sits on lost LLC EIN.
How Do You Get an EIN for an Estate?
The executor files Form SS-4 through 1 of 4 methods: online in about 15 minutes, by fax in 4 to 7 business days, by mail in 6 to 11 weeks, or by phone for an international applicant. All 4 cost $0 at the IRS.
| Method | Time to EIN | SSN needed? | IRS fee |
|---|---|---|---|
| IRS online assistant | About 15 minutes | Yes | $0 |
| Fax Form SS-4 | 4 to 7 business days | No | $0 |
| Mail Form SS-4 | 6 to 11 weeks | No | $0 |
| Phone, international only | On the call | No | $0 |

The executor selects Estate as the entity type on Form SS-4 and enters the date of death as the funding date. An executor with an SSN finishes online in about 15 minutes. An executor abroad faxes the signed form to 855-641-6935 within the US or 855-215-1627 from outside it, or calls the IRS international line at 267-941-1099 to receive the number on the call. Domestic questions run through the IRS at 800-829-4933. The full walkthrough sits on how to get an EIN, and a misplaced estate EIN is recovered on lost LLC EIN and how to verify an EIN.
After the IRS assigns the number, it mails the CP-575 confirmation letter, the 1 original notice printed per EIN. The executor keeps that letter with the letters testamentary and the estate's Form 1041 records for all 3 years the return can be examined. Confirming a number the executor already holds runs through how to verify an EIN, and the meaning of the 9-digit identifier sits on what is an EIN.
Does an Estate File Form 1041?
An estate files Form 1041, the income tax return for estates and trusts, once it has $600 or more of gross income in a tax year. Form 1041 is different from Form 706, the estate tax return, which applies only above the 2025 exemption of $13.99 million.
| Feature | Form 1041 | Form 706 |
|---|---|---|
| What it taxes | Income the estate earns after death | The transfer of the estate itself |
| Filing trigger | $600 of gross income | Gross estate above $13.99 million (2025) |
| Return type | Income tax return | Estate tax return |
| Who files it | The executor for the estate | The executor for a large estate |
| Uses the estate EIN | Yes | Yes |

Form 1041 taxes income the estate earns while probate is open, such as interest, rent, and dividends, once that income reaches $600. Form 706 is a separate return that taxes the value of the estate at transfer, and it applies only to the small share of estates that exceed the $13.99 million 2025 exemption. The executor files Form 1041 for the estate under the estate's own EIN, the identifier detailed on IRS EIN number.
The executor files the first Form 1041 for the tax year in which the estate reaches $600 of gross income, and the return is due by the 15th day of the 4th month after the estate's year-end. An estate can elect a fiscal year rather than the calendar year, giving the executor up to 12 months to gather the estate's income before the first filing. The number that goes on line 1 of Form 1041 is the estate's own 9-digit EIN, the identifier detailed on what is a FEIN.
Estate EIN vs Trust EIN?
An estate EIN covers the assets of a person who has died and files Form 1041 while probate is open. A trust EIN covers a trust, run by a trustee, that continues after death. Both are 9-digit EINs and each files Form 1041 at $600 of income.
| Feature | Estate | Trust |
|---|---|---|
| Entity begins | At the person's death | When the trust is created |
| Files Form 1041 at | $600 of gross income | $600 of gross income |
| Responsible party | Executor or administrator | Trustee |
| EIN format | 9 digits, XX-XXXXXXX | 9 digits, XX-XXXXXXX |
| Entity ends | When probate closes | When the trust terms are met |
A person's death can create both entities: the estate handles probate assets, while a trust holds assets the person moved into it during life. Each entity needs its own EIN, and each files its own Form 1041 once it earns $600. The trust side, including who signs Form SS-4 as trustee, sits on EIN for a trust. The cost of any EIN filing, and the $0 IRS fee, sits on LLC EIN cost.
