You're responsible for settling the estate, which means you'll need to get an EIN for the estate before the bank will let you deposit checks or pay bills on behalf of the deceased. It's a simple online form with the IRS, but there are a few questions that consistently trip people up if you don't know what they're asking. Here's what you need to prepare and how to avoid the common mistakes that cause delays or duplicate filings.
Key Takeaways:
- You can get a free estate EIN online in 10 minutes through the IRS EIN Assistant tool, if it happens to be working, it is often down
- Apply after receiving Letters Testamentary but before opening an estate bank account
- Estates earning over $600 in income must file Form 1041, even if no estate tax is owed
- Choose December as the closing month for predictable calendar-year tax filing deadlines
- Elayne automates estate administration including EIN filings, tax returns, and agency notifications
What Is an EIN and Why Your Estate Needs One
An Employer Identification Number, or EIN, is a nine-digit tax ID issued by the IRS to identify a legal entity for tax purposes. When someone passes away, their estate becomes its own legal entity, separate from the deceased, and it needs its own tax ID accordingly.
The deceased person's Social Security number cannot be used to open an estate bank account, file estate income taxes, or conduct most financial transactions on behalf of the estate. Banks require an EIN before opening an estate account, and the IRS requires one before accepting tax filings tied to the estate.
The EIN is, in short, the estate's financial identity.
When You Need to Apply for an Estate EIN
Timing matters more than most executors expect. The general rule: apply after receiving your court appointment letters (Letters Testamentary or Letters of Administration) but before opening an estate bank account. Banks won't move forward without an EIN in hand.
An EIN is required when:
- The estate earns more than $600 in income during administration, triggering the need to file a Form 1041 estate income tax return.
- You need to open a dedicated estate bank account to receive and distribute assets.
- You're transferring titled assets like real estate or brokerage accounts into the estate.
Some very simple estates with no income and no financial accounts may not technically need one. But in practice, most executors will need an EIN early in the process, and getting it before you need it prevents delays.
What Information You'll Need Before You Start
Having everything ready before you start the IRS online application saves real time. The session will time out if you pause too long, and you cannot save progress midway through.
Gather the following before you begin:
- Deceased person's full legal name, exactly as it appears on legal documents
- Deceased person's Social Security number
- Date of death
- Deceased person's last known mailing location
- Your full legal name as executor
- Your Social Security number
- Your mailing location
- The name and location of the estate, typically where the deceased last lived
- Your Letters Testamentary or Letters of Administration, which you will reference but not upload
One detail that trips people up: your name goes in as the "responsible party," not the deceased. The IRS treats the executor as accountable for the estate's tax obligations.

How to Apply for an Estate EIN Online (Step by Step)
The IRS EIN Assistant is a web-based intake system that collects entity classification data, taxpayer identification information, and fiscal year election inputs before issuing a federal tax identification number. The session runs in real time, with no save-and-resume functionality, meaning all required information must be on hand before the process begins. The application window is open Monday through Friday, 7 a.m. to 10 p.m. Eastern time, and the tool is known to go offline without notice, so having a fallback method ready is worth considering.
Below is a detailed walkthrough of each step, including where the application requires specific legal designations that are easy to misread:
- Go to the IRS EIN application page and select "Apply Online Now" — this initiates a new session that cannot be resumed if interrupted
- When prompted to select an entity type, choose "Estate" — not "Trust," "Individual," or any other classification, as the wrong selection cannot be corrected mid-session and will require starting over
- Enter the deceased person's full legal name exactly as it appears on government-issued documents, along with their Social Security number — these fields are cross-referenced against IRS records, and discrepancies can delay or reject the application
- Enter your own name and Social Security number in the "responsible party" fields — this designates you as the executor legally accountable for the estate's federal tax obligations, and it is a common point of confusion for first-time filers
- Confirm the estate's mailing address — typically the last known address of the deceased, which must match what appears on court-issued Letters Testamentary or Letters of Administration
- Select the closing month of the estate's accounting year — this is a fiscal year election with downstream consequences for Form 1041 filing deadlines; see the following section for a full breakdown before making this choice
- Review all entries carefully before submitting — the system does not provide an edit window after submission, and any errors will require a correction call to the IRS Business & Specialty Tax Line
Upon successful submission, the EIN is displayed once on the confirmation screen. It will not be accessible again through the online portal. Print the confirmation page or save it as a PDF immediately, and store it with the estate's core legal documents — alongside the Letters Testamentary, death certificate, and any court filings. If the confirmation page is closed before saving, the only recovery option is a manual lookup call to the IRS.
Understanding the Closing Month of Accounting Year
One question on the EIN application consistently stops executors cold: "Closing month of accounting year." It sounds like a question for accountants, but the answer is simpler than it appears.
For most estates, the answer is December. Choosing December means the estate follows a calendar year, which keeps filing deadlines predictable and aligns with standard IRS Form 1041 due dates.
Estates can technically elect a fiscal year ending in any month, which can offer some tax timing flexibility. But unless an estate attorney or CPA has recommended a different fiscal year, December is the right choice for nearly every executor filing independently.
The closing month chosen locks in when the estate's annual income tax return is due. A December year-end means the Form 1041 is due April 15 of the following year. A different month changes that deadline accordingly, which can create confusion when coordinating with financial institutions or beneficiaries.
When in doubt, choose December. A tax professional can always be consulted afterward if the estate's situation turns out to be more complex.
Alternative Ways to Apply for an Estate EIN
Online is fastest, but not always possible. Three other options exist.
Phone
Call the IRS Business & Specialty Tax Line at 800-829-4933, Monday through Friday, 7 a.m. to 10 p.m. Eastern. An agent will ask for the same information covered above and issue your EIN by the end of the call.
Fax
Complete Form SS-4 and fax it to the IRS. Turnaround is typically four business days.
Mail your completed Form SS-4 to the appropriate IRS office for your state. Expect four to five weeks for processing.
International applicants without a U.S. mailing location must apply by phone or mail, as the online tool is only available to domestic applicants. For anyone applying outside business hours, fax is the next-fastest route.

What Happens After You Receive Your EIN
Once the EIN is issued, the next step is opening the estate bank account. Bring the EIN confirmation, your Letters Testamentary, and a valid ID to the bank. Most institutions will also ask for the death certificate.
From there, the EIN goes on every estate-related tax filing, including Form 1041 for estate income taxes. Save the confirmation page or printed EIN letter in a secure place with the estate's other documents.
If the EIN gets misplaced, call the IRS Business & Specialty Tax Line at 800-829-4933. An agent can look it up once identity is verified. There is no fee to retrieve it.
Common Mistakes to Avoid When Applying for an Estate EIN
Four errors come up repeatedly in estate EIN applications, and each one can cause delays or require follow-up with the IRS.
The first is selecting the wrong entity type. The IRS online application lists both "Estate" and "Trust" as options, and choosing the wrong one means starting over.
- Entering the executor's SSN in the field meant for the deceased person's information is a common data entry slip that can invalidate the application.
- Applying before Letters Testamentary are issued leaves the executor without the legal authority needed to act on behalf of the estate, which the IRS may flag.
- Submitting the application more than once creates duplicate EINs, which requires a correction call to the IRS to resolve.
Estate Tax Filing Requirements and Thresholds
Two separate filing requirements often get confused: the federal estate tax return and the estate income tax return. They are not the same form, and they don't apply to the same estates.
The federal estate tax, filed on Form 706, only applies when the gross estate exceeds $15 million for individuals who die in 2026. Most estates fall well below that threshold and owe no federal estate tax at all.
Form 1041 is different. If the estate earns more than $600 in gross income during administration, filing is required regardless of estate size. Rental income, dividends, interest, and capital gains from sold assets all count toward that figure.

FAQ
How long does it take to get an EIN for an estate?
Your EIN appears immediately after submitting the online application through the IRS EIN Assistant tool. If you apply by phone, you'll receive it by the end of the call, while fax applications typically take four business days and mail applications take four to five weeks.
Can I use the deceased person's Social Security number instead of getting an EIN?
No, banks and the IRS require a separate EIN for the estate. The deceased person's Social Security number cannot be used to open estate bank accounts, file estate income tax returns, or conduct financial transactions on behalf of the estate.
What should I choose for the closing month of accounting year?
Choose December unless an estate attorney or CPA has recommended otherwise. December aligns the estate with a calendar year, keeping filing deadlines predictable and making Form 1041 due on April 15 of the following year.
When does an estate need to file a Form 1041 income tax return?
If the estate earns more than $600 in gross income during administration, filing Form 1041 is required. Rental income, dividends, interest, and capital gains from sold assets all count toward that $600 threshold, regardless of the estate's total value.
What happens if I lose my EIN confirmation after it's issued?
Call the IRS Business & Specialty Tax Line at 800-829-4933. An agent can look up your EIN once your identity is verified, and there is no fee to retrieve it.
