How to Get an EIN for an Estate
A bank, payer, or tax workflow may ask for an estate identification number before you know whether the estate actually needs one.
The short answer
An estate EIN identifies the estate as a separate tax or banking entity when that entity is required; it is not a court appointment and does not grant authority to act.
Use the current IRS application instructions and coordinate the entity name and responsible-party information with the estate's records.
Stop when authority is unresolved, multiple EINs may have been requested, the entity type is uncertain, or a third party is charging for an unnecessary application.

If you are authorized to administer your loved one's estate, you can apply directly to the IRS for an employer identification number, or EIN. Qualifying U.S. applicants can apply online, while fax and mail applications use Form SS-4 and certain international applicants may apply by telephone.
An EIN identifies the estate for federal tax reporting. It does not appoint you as executor, prove that an asset belongs to the estate, or give you permission to use a bank account.
First confirm who should apply
A personal representative is the person responsible for administering an estate. This person may be called an executor when named in a will or an administrator in other circumstances.
A will may nominate someone, but court appointment may still be required before that person has authority to act.
The Form SS-4 instructions identify the executor, administrator, personal representative, or other fiduciary as the responsible party for a decedent's estate. A fiduciary is someone entrusted to act for another person or an estate.
Before applying, confirm:
- You are authorized to act under the governing documents and applicable law.
- The tax ID is for the decedent's estate, not a trust, surviving joint owner, beneficiary, or continuing business.
That distinction matters when an account earns interest after your loved one passed away. IRS Publication 559 says the taxpayer identification number used for reporting is the number of the person or estate to whom the interest is payable.
The facts and applicable law determine whether the income belongs to an estate, trust, surviving owner, or beneficiary.
What the number does and does not do
An EIN is a nine-digit federal taxpayer identification number. Despite the word “employer,” an estate can need one even if it has no employees.
Publication 559 tells a personal representative to apply as soon as possible because the number is used on returns, statements, and other documents concerning the estate. It may also be given to payers reporting interest, dividends, or other income payable to the estate.
| Identifier | Whom it identifies | What it is not |
|---|---|---|
| Estate EIN | The estate for federal tax reporting | Proof of court authority |
| Loved one's SSN or ITIN | Your loved one as an individual | The estate's EIN |
| Fiduciary's SSN or ITIN | The responsible party on the application | The estate's EIN |
Obtaining an EIN and determining whether a particular return is required are separate decisions.
Gather the estate information
Use the current Instructions for Form SS-4 as the field-by-field authority. Gather:
- The estate's legal name. If there is no legal name, the instructions say to enter your loved one's name followed by “Estate.”
- The name and mailing address of the executor, administrator, personal representative, or other fiduciary.
- The fiduciary's SSN or ITIN for the responsible-party fields. The instructions specify a different entry for a foreign responsible party who has no SSN or ITIN and is ineligible to obtain one.
- Your loved one's full name and SSN or ITIN for the estate entity-type field.
- The physical location, mailing address, reason for applying, and other requested information.
Protect these identifiers. Do not put a full SSN, ITIN, or EIN in an unencrypted email, a shared family note, or a public document.
Keep the assignment notice with controlled estate tax records.
Choose one application route
Apply online when eligible
The IRS recommends applying electronically when possible. Its online EIN application page says the tool is available to qualifying applicants whose principal place of business is in the United States or a U.S. territory and who have the responsible party's SSN or ITIN.
The online application must be completed in one session and expires after 15 minutes of inactivity. Prepare first, then view, save, and print the confirmation letter at the end.
The IRS provides this route free of charge.
Apply by fax or mail
If the online route is unavailable or you are not eligible, complete and sign Form SS-4. Use the fax number or mailing address in the current official instructions, not one copied from an old article or saved form.
The December 2025 instructions say fax applications generally receive a response within four business days when a return fax number is provided. They advise mailing the form four to five weeks before the number is needed.
These estimates are not guarantees and can change, so recheck the live instructions before sending personal information.
Use the international telephone route if it applies
The current instructions reserve telephone applications for applicants with no legal residence, principal place of business, principal office, or agency in the United States or U.S. territories. The caller must be authorized to receive the number and answer the Form SS-4 questions.
Check the instructions for the current telephone number, hours, and follow-up requirements.
Use only one route. Applying through multiple methods can create more than one EIN for the same entity.
The current limit is one EIN per responsible party per day, and the instructions apply that limit to the decedent for an estate.
Illustrative scenario: three identities, three fields
Illustrative scenario. All names and facts are fictional.
Jordan Lee has been appointed personal representative of Morgan Lee's estate in State A. Assume the appointment and local-law questions have been resolved.
An account held only in Morgan's name continues to earn interest after Morgan passed away, and the bank confirms that the interest is payable to the estate.
The estate has no separate legal name, so Jordan follows the current instructions and enters “Morgan Lee Estate.” Jordan is the fiduciary and supplies Jordan's own taxpayer identification number in the responsible-party field. Morgan's taxpayer identification number goes in the estate entity-type field.
The new EIN identifies Morgan Lee Estate.
Jordan saves the assignment notice and asks the bank which documents it requires for tax reporting. The number does not prove Jordan's court authority, and this scenario does not decide who owns any real account.
After the EIN is assigned
- Save the assignment notice and a controlled backup.
- Use the same estate name that appeared on the application.
- Share the number only with an institution, payer, court, tax professional, or agency that legitimately needs it.
- Ask each institution which separate evidence of fiduciary authority it requires.
- Determine which federal and state returns apply. Receiving an EIN does not by itself mean Form 1041 is required or resolve state filing duties.
- If the mailing address or responsible party changes, check the current Form 8822-B rules. The present instructions require a responsible-party change to be reported within 60 days.
The EIN is federal. State tax agencies may have separate registrations, returns, or identification numbers.
Probate courts determine authority under state law, and financial institutions have their own document and identity-verification procedures within applicable law.
When professional help matters
Talk with a probate attorney or qualified tax professional before applying if authority is disputed, no fiduciary has been appointed, a trust may be involved, ownership of income is unclear, the estate operates a business, there is an international connection, or an EIN may already exist.
A court clerk can explain filing logistics but cannot provide legal advice. An accountant or enrolled agent can help with federal tax administration.
An attorney can address authority, title, and local probate law. Some estates need both kinds of help.
Continue with the next responsible step
Use the executor checklist to place tax administration in the broader sequence. If the number relates to an account, review what happens to a bank account after death before assuming the account belongs to the estate.
