How To Get An Estate Tax ID Number: The Definitive Step-by-Step Guide
Securing an estate tax ID number, formally known as an Employer Identification Number (EIN), is a mandatory legal and financial step required to manage a deceased person's assets, open a bank account for the estate, and file fiduciary tax returns. The process is handled directly through the Internal Revenue Service online portal and can be completed instantly, provided you possess the decedent's correct Social Security Number and official documentation establishing your legal authority.
Pre-Procedure Planning & Estate Setup Requirements
Before you begin the application process for an estate tax ID number, you must establish proper legal standing and gather the foundational documentation required by the Internal Revenue Service. Attempting to apply without the correct legal authority or missing identification details will result in application rejections, processing delays, or compliance issues with the probate court.
- Essential Documentation & Information: Official death certificate, the decedent's full legal name and Social Security Number, your legal appointment papers (such as Letters Testamentary or Letters of Administration issued by the probate court), and your own Social Security Number or Individual Taxpayer Identification Number as the applicant or executor.
- Prerequisite Knowledge & Standards: Understanding that an estate is a separate legal and tax entity distinct from both the decedent and the executor. You must operate under Internal Revenue Code guidelines for fiduciary responsibilities, which include tracking date-of-death asset valuations and keeping meticulous accounting records.
- Budget & Duration Benchmarks: The official application through the Internal Revenue Service website is entirely free. The online application takes approximately fifteen minutes to complete, and the EIN is issued immediately upon successful submission.
Step-by-Step Estate Tax ID Number Execution Workflow
Step 1: Verify Your Legal Authority as Executor or Administrator
Before applying for the EIN, you must be officially appointed by a probate court or named as the qualified trustee of a living trust that has now become irrevocable. The Internal Revenue Service requires the applicant to act as the "responsible party," defined as the person who owns or controls the entity or, in the case of an estate, the fiduciary managing the estate assets.
- Locate the original Last Will and Testament or verify intestacy statutes if no will exists.
- File a petition for probate with the local county court to officially open the estate.
- Obtain certified copies of the Letters Testamentary or Letters of Administration from the court clerk, as these documents prove your legal standing to third parties like banks and the Internal Revenue Service.
Warning: Do not apply for an estate tax ID number using informal authority or prior to receiving court appointment papers, as this can create conflicting tax identification records and complicate the probate administration process.
Step 2: Access the Official Internal Revenue Service Online EIN Assistant
The most efficient method to acquire an estate tax ID number is by utilizing the digital application portal hosted on the official Internal Revenue Service website during their operational hours (Monday through Friday, 7:00 AM to 10:00 PM Eastern Standard Time).
- Navigate to the official Internal Revenue Service website and locate the "Apply for an Employer Identification Number Online" tool.
- Review the opening disclosure and click the button to begin the application.
- Select "Estate" from the list of entity types presented on the screen. Read the descriptive text to ensure you have chosen the correct legal classification.
Step 3: Complete the Online Application Prompts and Verify Data
The online interview will guide you through a series of screens requesting specific administrative, geographical, and personal data regarding the decedent and the estate.
- Enter the legal name of the estate, typically formatted as "Estate of [Decedents Full Legal Name]," along with the physical address where estate business will be conducted and tax documents mailed.
- Input the decedent's Social Security Number, date of death, and the state where the probate administration is officially registered.
- Designate yourself as the responsible party by entering your full legal name and your personal Social Security Number or Individual Taxpayer Identification Number.
Pro-Tip: Double-check the spelling of the decedent's name and ensure the Social Security Number matches government records exactly. A single typo on this screen will trigger an automated system rejection and force you to restart the application or submit documentation by mail.
Step 4: Review, Submit, and Save the Official EIN Confirmation Notice
Upon completing the final prompt of the online wizard, the system will present a comprehensive review screen detailing all the data you entered during the session.
- Carefully verify every data field, paying close attention to names, identification numbers, and addresses.
- Submit the application to the Internal Revenue Service processing server.
- View the official EIN Confirmation Letter (Notice CP 575) on your screen and immediately download, save, and print multiple physical copies for your legal and financial records.

- Actionable Fix: Print and complete a physical Form SS-4 (Application for Employer Identification Number) and mail or fax it to the appropriate Internal Revenue Service campus along with a copy of the death certificate.

Frequently Asked Questions
Is an estate tax ID number legally required for every deceased person?
An estate tax ID number is required if the estate generates income after the date of death (such as rental income, dividends, or interest), if the estate is required to file a Form 1041 (U.S. Income Tax Return for Estates and Trusts), or if the estate must hire employees. If the estate transfers assets immediately without generating income or holding accounts, an EIN may not be necessary, though most financial institutions still require one to open an estate bank account.
Can I use the decedent's Social Security Number after they pass away?
No. Using a deceased person's Social Security Number for financial transactions, opening new accounts, or filing tax returns for estate income after their date of death is illegal and constitutes identity fraud. All estate financial activities conducted after death require a newly issued estate tax ID number.
How long does it take to receive the estate tax ID number?
When applying through the official online assistant on the Internal Revenue Service website, the estate tax ID number is generated and issued instantly upon final submission. If you apply by fax, processing typically takes four business days, while mail applications can take between four to six weeks.
What should I do with the estate tax ID number once the estate administration is complete?
Once all debts, claims, and taxes are settled, and the remaining assets are fully distributed to the beneficiaries, you will file a final fiduciary income tax return indicating that it is a final return. You do not need to formally notify the Internal Revenue Service to close or cancel the EIN, as the account simply becomes inactive once the final tax obligations are fulfilled.
