Does an estate need an EIN?
Yes. An EIN for an estate is required because the estate is a separate taxpayer from the person who died. The executor applies on Form SS-4, the IRS charges $0, and the decedent's SSN stops working at death.
A death splits one taxpayer into two. Everything the person earned up to the date of death reports on a final Form 1040 under their Social Security Number. Everything the property earns after that date — bank interest, a dividend, rent, a capital gain on a sale — belongs to the estate, and the estate reports it under its own 9-digit number.
That is why banks refuse to open an estate account on a death certificate alone. The account needs a taxpayer, the taxpayer needs an EIN, and the EIN arrives on an IRS CP-575 letter. The estate exists from the date of death forward, and its first tax year starts on that date.

When does an estate need an EIN?
An estate needs an EIN the moment it holds an asset, opens a bank account, or earns income. Form 1041 becomes due once the estate's gross income reaches $600 in a tax year, and every 1041 requires the EIN.
| Situation | EIN needed | Why |
|---|---|---|
| The estate opens a bank account | Yes | The bank reports interest to a taxpayer, and the taxpayer is the estate |
| Gross income reaches $600 in a tax year | Yes | Form 1041 is due, and the return prints the EIN |
| A beneficiary is a nonresident alien | Yes | Form 1041 is due at any income level |
| The estate sells real property | Yes | The sale reports under the estate, not the decedent |
| The estate pays wages to a household worker | Yes | Payroll filings need an employer number |
| Everything passed by beneficiary designation | No | No estate property, no estate return |
| A small estate transferred by affidavit | No | No probate estate exists to report |

The $600 line counts gross income, not profit. An estate whose only asset is a savings account files Form 1041 for the year its interest reaches $600, even when the estate ends that year holding less than it started. A nonresident alien beneficiary removes the $600 test entirely: the return is due at any income level. Either way the 1041 is due on the 15th day of the 4th month after the estate's tax year closes, and Form 7004 extends that date by 5 and a half months.
Who applies for the estate EIN?
The executor, administrator, or personal representative applies. That person's name goes on line 3 of Form SS-4 and on line 7a as the responsible party. The IRS accepts one responsible party, and it must be a person.
The title changes with the state and with the paperwork. A will names an executor. A court appoints an administrator when no will exists. Several states call both a personal representative. All three complete the same Form SS-4, and all three sign it in the same block at the bottom of the page.
Line 7a takes a human being. A law firm, a bank trust department, and an accounting practice each fail that test, even when the same firm handles the whole administration. Co-executors pick one of the two for line 7a. The other co-executor keeps every legal power the court granted, because line 7a describes an IRS contact and not the chain of authority.
Form 56 tells the IRS a fiduciary now stands in for the taxpayer. It carries the executor's own name and SSN, and it is a separate filing from Form SS-4. Filing Form 56 early routes IRS notices about the decedent to the executor instead of an empty mailbox.
How do you apply for an EIN for an estate?
File Form SS-4. Executors with an SSN or ITIN file free at irs.gov in 15 minutes. Executors with neither enter Foreign on line 7b and fax the form to 855-641-6935, or 855-215-1627 from outside the United States.
The estate EIN application in 5 steps
- Collect the death certificate and the court appointment (5 minutes). You need the decedent's full legal name, their SSN, and the date of death exactly as the certificate prints them.
- Write line 1 as Estate of plus the decedent's name (2 minutes). Copy the wording the probate court used. Line 3 then takes your own name as executor.
- Answer line 9a and line 11 (3 minutes). Check the Estate box on line 9a, enter the decedent's SSN beside it, and put the date of death on line 11.
- Set line 7b and line 12 (3 minutes). Line 7b takes your SSN, your ITIN, or the word Foreign. Line 12 takes December or your chosen fiscal year end.
- Sign, date, and send (2 minutes). An unsigned SS-4 gets returned. Fax to 855-641-6935, or 855-215-1627 from outside the US.
The five steps take 15 minutes with the death certificate and the court appointment in front of you. The IRS online assistant runs Monday to Friday, 7 a.m. to 10 p.m. Eastern, ends the session after 15 minutes of inactivity, and issues one EIN per responsible party per day. Preparation is not the slow part of an estate EIN. IRS processing is.
Which SS-4 lines does an estate fill in differently?
Four lines change for an estate. Line 1 takes Estate of plus the decedent's name, line 3 takes the executor, line 9a checks the Estate box with the decedent's SSN, and line 11 takes the date of death.
| Line | Field | What an estate enters |
|---|---|---|
| 1 | Legal name of the entity | Estate of, then the decedent's full legal name |
| 2 | Trade name | Blank |
| 3 | Executor, administrator, trustee, care-of name | The executor or personal representative |
| 4a and 4b | Mailing address | The executor's mailing address |
| 6 | County and state of the principal location | The county and state of the probate court |
| 7a | Name of the responsible party | The executor, as a person |
| 7b | SSN, ITIN, or EIN of the responsible party | The executor's SSN or ITIN, or the word Foreign |
| 9a | Type of entity | Check Estate, then enter the decedent's SSN |
| 10 | Reason for applying | Banking purpose, or Other with a written description |
| 11 | Date the business started or was acquired | The date of death |
| 12 | Closing month of the accounting year | December, or the estate's chosen fiscal year end |
| 13 | Highest number of employees expected in 12 months | 0 in all three boxes |

Line 1: Legal name of the entity
Enter: Estate of, then the decedent's full legal name
Write it the way the probate court wrote it. A line 1 that reads only the person's name, with no Estate of in front, is the single largest cause of estate rejections.
Line 2: Trade name
Enter: Blank
An estate trades under no other name. Line 2 stays empty for every estate application.
Line 3: Executor, administrator, trustee, care-of name
Enter: The executor or personal representative
Line 3 is the field estates were built for. The name here decides where the IRS mails the CP-575 confirmation letter.
Line 4a and 4b: Mailing address
Enter: The executor's mailing address
The IRS accepts a foreign mailing address. Enter the province and postal code in the line 4b fields, then the country. The CP-575 travels to this address once.
Line 6: County and state of the principal location
Enter: The county and state of the probate court
Estates use the jurisdiction that opened probate, not the state where a beneficiary lives.
Line 7a: Name of the responsible party
Enter: The executor, as a person
The IRS accepts one responsible party per application and it must be an individual. A law firm, a bank trust department, or an accounting practice on line 7a triggers rejection.
Line 7b: SSN, ITIN, or EIN of the responsible party
Enter: The executor's SSN or ITIN, or the word Foreign
Line 7b decides your route. An executor holding neither an SSN nor an ITIN writes Foreign, and the application leaves the online tool for the fax line.
Line 9a: Type of entity
Enter: Check Estate, then enter the decedent's SSN
The Estate box on line 9a asks for the decedent's Social Security Number in the field beside it. That number identifies the person; the new EIN identifies the estate.
Line 10: Reason for applying
Enter: Banking purpose, or Other with a written description
Banking purpose is the accurate box when the EIN exists to open the estate account. Estate administration written on the Other line is the alternative.
Line 11: Date the business started or was acquired
Enter: The date of death
The estate came into existence on the date of death. A line 11 carrying the probate filing date or the date the will was signed does not match the record.
Line 12: Closing month of the accounting year
Enter: December, or the estate's chosen fiscal year end
An estate picks the last day of any month within 12 months of the date of death. A trust holds no such choice. December keeps the estate on the calendar year.
Line 13: Highest number of employees expected in 12 months
Enter: 0 in all three boxes
Agricultural, household, and other each need a number. Enter 0 three times when the estate runs no payroll. A blank line 13 is an incomplete form.
Every field on the form has a rule behind it. The complete walkthrough of all 18 numbered fields sits on the ss4 form checklist.
How do you get an estate EIN without an SSN?
Enter the word Foreign on line 7b. The IRS issues estate EINs to executors who hold no SSN and no ITIN. The application moves from the online tool to the fax line, and no passport is required.
| Channel | Number | Who uses it |
|---|---|---|
| IRS fax, US-based estate | 855-641-6935 | Probate opened in a US state |
| IRS fax, international | 855-215-1627 | The estate has no US address |
| IRS international phone line | 267-941-1099 | Executors calling the IRS from outside the US |
Source: IRS, verified July 2026.
Two facts settle the questions that follow. The IRS asks for no Social Security Number on line 7b, and the IRS asks for no identity document with Form SS-4. Line 7b carries one word, and the IRS accepts it. Line 9a still needs the decedent's SSN, because that field identifies the person who died and not the executor filing the form.
An executor living abroad enters a foreign mailing address on lines 4a and 4b, including the province, the postal code, and the country. The CP-575 letter travels to that address. The IRS mails it once, so a reliable address matters more here than anywhere else on the form.
How long does an estate EIN take?
An estate EIN filed online with an SSN issues in one 15-minute session. Faxed forms take days to weeks. Mailed forms take 4 weeks. einnumber.co faxes the SS-4 within 5 business days, or 24 hours on Fast.
| Method | Time to EIN | SSN required | Cost |
|---|---|---|---|
| IRS online assistant | 15 minutes | Yes | $0 |
| IRS fax, Form SS-4 | Days to weeks | No | $0 |
| IRS mail, Form SS-4 | 4 weeks | No | $0 |
| IRS international phone | One call | No | $0 |
| einnumber.co Standard | 12–14 business days total | No | $67 |
| einnumber.co Fast | Under a week | No | $97 |
Source: IRS Form SS-4 instructions, verified July 2026. Business days are Monday to Friday, excluding US federal holidays.
einnumber.co faxes the SS-4 within 5 business days of receiving your completed details, and within 24 hours on the $97 Fast tier. Your filing confirmation email prints the date the form went to the IRS. Standard runs 12–14 business days total; Fast lands under a week.
Timing matters more for an estate than for a company, because probate runs on court dates. An estate account that opens 4 weeks late holds up every distribution behind it, and the fax route carries no tracking number and no status page to check.
What does the executor do after the estate EIN arrives?
Open the estate bank account, then file Form 1041 for every tax year with gross income of $600 or more. A calendar-year 1041 is due April 15. The decedent's final Form 1040 stays under the SSN.
| Form | What it covers | Deadline | Filed under |
|---|---|---|---|
| SS-4 | The estate EIN application | Before the estate account opens | The estate |
| 56 | Notice of the fiduciary relationship | As soon as the court appoints you | Executor's SSN |
| 1040 (final) | Income up to the date of death | April 15 after the year of death | Decedent's SSN |
| 1310 | A refund claim for the decedent | With the final Form 1040 | Decedent's SSN |
| 1041 | Estate income of $600 or more | 15th day of the 4th month after year end | Estate EIN |
| 7004 | Extension for Form 1041 | By the Form 1041 due date | Estate EIN |
| 706 | Federal estate tax return | 9 months after the date of death | Estate EIN |
| 4768 | Extension for Form 706 | By the Form 706 due date | Estate EIN |
Source: IRS form instructions, verified July 2026.
Form 7004 extends the Form 1041 deadline by 5 and a half months. Form 4768 extends Form 706 by 6 months. Both extend the filing date and neither extends a payment date, so the estate pays on the original deadline either way.
Two elections turn on the calendar. Section 663(b) treats a distribution made in the first 65 days of a tax year as made on the last day of the prior year, which moves income to the beneficiaries a year earlier. Section 645 lets the executor and a trustee treat a qualified revocable trust as part of the estate on Form 8855, and that election period runs 2 years from the date of death when no Form 706 is required.
Form 4810 asks the IRS for a prompt assessment and shortens the assessment window to 18 months. Executors use it before making final distributions, because personal liability follows an executor who distributes an estate with taxes outstanding.
The EIN itself needs nothing after it arrives. An EIN never renews and never expires, which puts the year 2 cost at $0 and every year after that at $0. When probate closes, the estate files a final Form 1041 marked as the final return; the number is not cancelled.
Is an estate EIN different from a trust EIN?
Yes. An estate EIN covers property passing through probate and checks the Estate box on line 9a. A trust EIN covers a trust and checks the Trust box. A testamentary trust receives its own EIN, separate from the estate.
| Question | Estate | Trust |
|---|---|---|
| Line 9a box | Estate, plus the decedent's SSN | Trust, plus the grantor's SSN |
| Line 3 name | Executor or administrator | Trustee |
| Line 11 date | The date of death | The date the trust was funded |
| Fiscal year choice | Any month end within 12 months of death | Calendar year |
| Income return | Form 1041 at $600 of gross income | Form 1041 at $600 of gross income |
| Lifespan | Ends when probate closes | Runs until the trust terminates |
One death produces both numbers in many families. The will funds a testamentary trust, so the estate takes 1 EIN and the trust takes a second. The fiscal-year choice is the sharpest practical difference: an estate ending its tax year on, for example, the last day of the 11th month after death splits income across 2 returns and shifts a distribution deadline with it.
The trustee's side of the same event has its own procedure. Read it on the ein for trust page, which covers which trusts need a number and what changes on the grantor's death.
Why do estate EIN applications get rejected?
A line 1 name that omits Estate of causes most estate rejections. Three more causes: a firm named on line 7a, a blank line 13, and a line 11 date that is not the date of death.
Line 1 omits Estate of. The decedent's name alone names a person, not an estate. Match the wording on the court appointment.
Line 7a names a firm. The IRS requires an individual. A law firm, a bank trust department, or an accountant on line 7a fails.
Line 9a has no decedent SSN. The Estate box asks for the SSN of the person who died. The box checked with an empty field is incomplete.
Line 11 is not the date of death. The estate started the day the person died. A probate filing date or a will signing date does not match the record.
Line 13 is blank. All three boxes need a number. Enter 0 for agricultural, household, and other when the estate hires nobody.
The form is unsigned. An unsigned SS-4 gets returned unprocessed, and the wait restarts from zero.
The IRS reports a rejection by mail, not by email. A rejected fax filing costs weeks before the notice reaches the executor, and the estate account waits the whole time. Reading line 1 against the court appointment takes 2 minutes and removes the largest single cause.
Related entity routes: the ein for sole proprietorship route answers line 9a with a different box and reports under the owner's SSN by default.
How much does an EIN for an estate cost?
$0. The IRS charges nothing for Form SS-4 and nothing for the estate's EIN, through every filing method. An estate EIN costs $0 in year 2 as well, because an EIN never renews. einnumber.co charges $67 or $97 once.

The $67 exists for the executors the online tool blocks: a paper form, a fax line with no tracking, and the 12 SS-4 fields an estate completes — four of them estate-specific — that have to be right the first time.
When that is your situation, get it filed within 5 business days, guaranteed — we prepare the form, verify the estate name against your court appointment, and fax it to the IRS.
