How to Get an EIN for an Estate: Complete Guide for Executors and International Heirs
If you’ve just been named executor of an estate, one task sits at the top of your list before anything else can move forward: obtaining an Employer Identification Number (EIN). Without this federal taxpayer identification number, you cannot open a dedicated bank account, file tax returns, or legally act on behalf of the estate. The IRS treats every estate as its own taxable entity a distinct business entity for tax purposes the moment the deceased person passes, and the clock starts immediately. Whether you plan to complete the online EIN application in under 15 minutes, or need to mail or fax Form SS-4 due to international circumstances, understanding the full application process protects you from costly mistakes. This guide provides a clear, practical overview for any executor, administrator, trustee, attorney, or even Canadian company representative dealing with US-based estates. From completing the official IRS form to receiving your EIN confirmation letter, we’ll walk through each step and share essential tips no prior tax planning experience required.

What Is an EIN and Why Does an Estate Need One?
An EIN is a 9-digit tax identification number assigned by the IRS to identify a taxable entity. While commonly associated with businesses, an estate is also treated as its own business entity for tax purposes once the decedent passes away.
The deceased person’s Social Security Number can no longer be used for new financial transactions after death. Any income the estate generates during the settlement period interest, rent, dividends, capital gains from asset sales must be reported under a separate taxpayer identification number. That number is the estate’s EIN.
Without it, the executor administrator cannot open a dedicated estate bank account, file the estate’s income tax return (Form 1041), or issue 1099 forms to contractors or beneficiaries. This also applies to any estate tax obligations that may arise depending on the value of the assets.
| Decedent’s SSN | Estate EIN | |
|---|---|---|
| Purpose | Identifies the individual | Identifies the estate as a taxable entity |
| Used by | The deceased person (during lifetime) | The executor or personal representative |
| Tax forms | Form 1040 (final return) | Form 1041 (estate income tax return) |
When Is an EIN Required for an Estate?
Not every estate needs an EIN. The IRS requires one when:
- The estate earns more than $600 in gross income during the tax year and is required to file Form 1041
- The executor needs to open a bank account in the estate’s name
- The estate has employees (rare, but possible for estates with ongoing businesses)
- The estate must issue 1099 forms or handle business tax obligations tied to the decedent’s former activity
If the estate consists solely of assets transferred directly to beneficiaries with no income generated during settlement an EIN may not be necessary. When in doubt, applying for one is free and avoids complications later.
Who Can Apply for an Estate EIN?
The IRS requires a “responsible party” on every EIN application. For an estate, this is typically the executor administrator or personal representative not a trustee, unless the assets have already transferred into a trust.
The Executor or Administrator Named in the Will
The executor named in the will applies using their own SSN or ITIN. They must have received Letters Testamentary from the probate court before applying. In intestate cases (no will), the court-appointed administrator serves the same role, using Letters of Administration as proof of authority. The principal officer of the estate is always the person the court has formally designated.
An International Executor Without a SSN
An international executor without a SSN faces additional steps. The online EIN application requires a SSN or ITIN neither of which a foreign executor may have. In this case, the executor must either obtain an ITIN first (Form W-7, which takes 7 to 11 weeks) or apply for the EIN by phone using Form SS-4, calling the IRS international line directly. Providing your legal residence principal address on the form is mandatory regardless of the method chosen.
Can an Attorney or CPA Apply on Your Behalf?
Yes. A CPA or attorney can apply on the executor’s behalf by completing Line 18 of Form SS-4 as a third-party designee. This requires a Power of Attorney (Form 2848) and is the most practical solution for executors located outside the United States. This personal service eliminates the burden of navigating IRS procedures from abroad.
Documents and Information You Need Before Applying
Gather everything before starting the application process. Incomplete information is the most common cause of delays. Having documents ready also helps prevent identity theft risks associated with transmitting sensitive data multiple times.
| Document / Information | Where to Get It |
|---|---|
| Deceased person’s full legal name and SSN | Death certificate, SSA records |
| Decedent’s date of death | Death certificate |
| Executor’s full name and SSN or ITIN | Personal ID, IRS |
| Letters Testamentary or Letters of Administration | Probate court |
| Estate mailing address (legal residence principal) | Determined by the executor |
| Reason for applying | Select “Estate of a deceased individual” |
How to Apply for an EIN for an Estate Step by Step
Method 1 Online EIN Application (IRS.gov)
The fastest method. Available Monday through Friday, 7 a.m. to 10 p.m. Eastern Time. The EIN is issued immediately upon completion.
- Go to the IRS EIN Assistant at irs.gov
- Select “Estate” as the business entity type not “Sole Proprietor” or “LLC.” Check this box carefully, as selecting the wrong category is the most common error
- Confirm you are the executor or authorized representative, then hit the continue button
- Enter the deceased person’s name, SSN, and date of death
- Enter your personal information (SSN or ITIN required)
- Submit and receive your EIN confirmation
Method 2 Phone Application (Required for International Applicants)
Call the IRS Business & Specialty Tax Line. This is the only real-time option for applicants without a SSN or ITIN. The international number is (267) 941-1099 (not toll-free). Hours: Monday–Friday, 6 a.m.–11 p.m. Eastern Time. The EIN is issued during the call.
Method 3 Fax (Form SS-4)
Complete Form SS-4 following the instructions for form SS-4 provided by the IRS and fax it to (855) 641-6935. Processing takes approximately 4 business days. Useful for international applicants in time zones that make phone calls impractical.
Method 4 Mail (Form SS-4)
The slowest method: 4 to 6 weeks. Filing Form SS-4 by mail to the IRS at the address listed in the instructions is only recommended as a last resort.
| Method | SSN/ITIN Required? | Processing Time | Best For |
|---|---|---|---|
| Online | Yes | Immediate | US-based executors |
| Phone | No | Same day | International executors |
| Fax | No | ~4 business days | International (time zone issues) |
| No | 4–6 weeks | Last resort |
How Long Does It Take and How Much Does It Cost?
For a domestic executor with a SSN, the EIN is available the same day via the online EIN application. For an international executor who first needs an ITIN, the realistic timeline extends to 8 to 14 weeks (ITIN processing plus EIN application process).
The EIN itself is completely free from the IRS. Paid services charge $49 to $199 for what amounts to filling out the same form. The real value of working with a CPA firm is not the filing itself it’s ensuring the correct business entity classification, proper responsible party designation, and compliance with downstream tax obligations including estate tax, business tax, and international reporting.
What Happens After You Receive the Estate EIN
Getting the EIN is only the first step. Several obligations follow immediately.
Open an estate bank account. The executor administrator must keep estate funds separate from personal funds. Commingling is a breach of fiduciary duty. Most banks require the EIN confirmation letter, Letters Testamentary, the death certificate, and the executor’s ID.
File Form 1041 if the estate earns more than $600 in gross income. The executor is required to file this return and chooses the estate’s fiscal year either a calendar year or a fiscal year ending within 12 months of the date of death. Income distributed to beneficiaries is reported on Schedule K-1, and each beneficiary must then include those amounts on their own tax returns.
Report foreign accounts. If the estate holds financial accounts outside the United States, the executor may need to file FinCEN Form 114 (FBAR) and potentially Form 8938 (FATCA). This is a frequently overlooked obligation, especially for estates with international assets.
Special Situations for International Executors
Most online guides assume the executor is a US resident with a SSN. For international families, the reality is different.
When the executor lives outside the United States, challenges include: no SSN or ITIN, time zone barriers for IRS phone calls, and difficulty providing a US mailing address or legal residence principal address. Working with a US-based CPA firm that holds Power of Attorney is typically the most efficient solution.
When a US citizen dies in France or a French person inherits US assets the estate EIN is the starting point of a cross-border tax process. The US-France tax treaty (1994) determines how estate income is taxed during settlement, which country has primary taxing rights, and what credits are available to avoid double taxation. French succession declarations run in parallel with IRS Form 1041 filings, and coordination between the two systems requires specialized expertise. Any trustee managing assets post-settlement faces a separate set of obligations under both jurisdictions.
Common Mistakes When Applying for an Estate EIN
- Selecting the wrong business entity type choosing “Sole Proprietor” or “LLC” instead of “Estate” when you check this box in the application
- Applying before receiving Letters Testamentary from the probate court
- Confusing an estate EIN with a trust EIN these are separate entities requiring separate numbers, each with its own trustee or executor administrator
- Using the deceased person’s SSN for new financial transactions after death
- Skipping the ITIN step as an international executor, then being blocked by the online EIN application
Frequently Asked Questions
Can I use my own SSN instead of getting an EIN for the estate?No. Once the estate generates income or requires a bank account, a separate EIN is required. Using your personal SSN creates reporting confusion on your tax returns and potential audit triggers.
Can a foreign entity or Canadian company get an EIN?Yes. Any foreign person or entity with US tax obligations can obtain an EIN via Form SS-4 by phone, fax, or mail. The online EIN application is not available without a SSN or ITIN.
Is the EIN the same for an estate and a trust?No. If the will creates a testamentary trust, a second EIN must be obtained once assets transfer from the estate into the trust. The trustee becomes the responsible party for the new number.
What if the executor changes do I need a new EIN?The EIN stays with the estate. However, the IRS must be notified of the change in responsible party whether a new executor administrator or principal officer using Form 8822-B.
How do I protect the estate from identity theft during the application process?Never share the EIN or deceased person’s SSN via unsecured email. Use the IRS online EIN application or phone line directly, and store the confirmation letter in a secure location. If you suspect the decedent’s SSN has been compromised, notify the IRS Identity Protection Specialized Unit.
