An executor in Manhattan receives Letters Testamentary from the Surrogate’s Court, granting her the authority to manage her father’s estate. She walks into his bank, documents in hand, to open an estate account and consolidate his finances. The bank manager stops her. “I’m sorry,” he says, “but we can’t open an account without an EIN for the estate.” This common roadblock exists for a reason: upon a person’s death, their estate becomes a distinct legal entity with its own tax identity.
The deceased’s Social Security Number dies with them. From that moment on, any income the estate generates—interest from a savings account, dividends from stock, rent from a property—must be reported to the IRS under a new number. That number is the Employer Identification Number, or EIN.
An Estate Is a Separate Taxpayer
I often explain to new executors that they are not just managing the deceased’s old accounts. They are now the steward of a new, temporary entity: the estate. Think of the estate as a new business that exists for one purpose—to gather the deceased’s assets, pay their final debts and taxes, and distribute what remains to the beneficiaries. Like any business, it needs a federal tax ID number.
Without an EIN, an executor cannot perform their most basic duties. You cannot open a bank account in the name of the estate. You cannot file the estate’s income tax return, IRS Form 1041, which is required if the estate earns over $600 in gross income in a year. You cannot transfer assets like stocks or bonds into the estate’s name before distribution. The EIN is the key to conducting the estate’s financial affairs.
Applying for this number is one of the first steps a newly appointed fiduciary should take, right after being formally appointed by the court.
The Fiduciary’s Role in the EIN Application
Only the court-appointed executor or administrator has the legal authority to apply for an EIN on behalf of an estate. This person is the “responsible party” in the eyes of the IRS. Before you can begin the application, you must have the legal standing granted by the New York Surrogate’s Court, typically in the form of Letters Testamentary (if there was a will) or Letters of Administration (if there was no will).
This authority is not just procedural—it comes with significant legal obligations. As a fiduciary, you have a duty to act prudently in the best interest of the estate and its beneficiaries. This responsibility is codified in New York law. For example, EPTL § 11-1.1 grants fiduciaries broad powers to manage estate property, but these powers must be exercised with care. Securing an EIN promptly is a foundational act of that prudent management.
When we represent an executor, we handle this application as a matter of course. The process itself is straightforward, but the information must be precise. The application, IRS Form SS-4, asks for:
- The full legal name of the estate (e.g., “Estate of John Smith, Deceased”)
- The name and Social Security Number of the executor or administrator
- The type of entity—in this case, “Estate”
- The date the estate was “created”—which is always the date of death
Accuracy is critical. A mistake in the estate’s name or the fiduciary’s information can create mismatches with bank records and tax filings, causing significant delays.
Securing the EIN: The Practical Steps
There are three primary ways to apply for an EIN for an estate: online, by fax, or by mail. For nearly every client, we use the IRS’s online portal. It is the fastest method, providing the EIN immediately upon successful completion of the application. There is no fee to apply.
The online application is an automated interview that walks you through the required information. It requires the responsible party—the executor—to have a valid Social Security Number or Individual Taxpayer Identification Number. Once the information is validated, the EIN is issued in a printable PDF. This allows the executor to walk into a bank that same day and open the necessary accounts.
Applying by fax or mail is an option, but it is much slower, often taking weeks. In an estate administration where time can be critical—for stopping automatic payments, securing assets, or meeting tax deadlines—the delay is rarely advisable. Whichever method is chosen, the goal is the same: to create the official identity for the estate so the work of stewardship can begin.
If you have been named the executor of a will, your first formal step is petitioning the Surrogate’s Court for the authority to act. If you need guidance preparing that petition or understanding the duties that follow, including obtaining an EIN, our firm can schedule an initial consultation to review the will and outline the administration process ahead.
