How To Get A Tax ID Number For A Trust
Obtaining a Tax ID number, officially known as an Employer Identification Number or EIN, for a trust requires understanding the specific legal classification of the entity and filing Form SS-4 with the Internal Revenue Service. This nine-digit identifier is mandatory for opening bank accounts, filing annual fiduciary tax returns, and managing asset distribution for beneficiaries.
Preparing to Secure Your Trust's Federal Tax Identifier
Establishing a federal tax identification number for a trust requires careful alignment with the legal structure outlined in your trust agreement. Before initiating contact with the Internal Revenue Service, you must verify the legal status of the trust, distinguishing clearly between revocable living trusts and irrevocable trusts, as this dictates how income is reported and whether the grantor or the trust itself pays the associated taxes.
- Essential Documentation & Information: A finalized and signed trust document, the exact legal name of the trust, the date of trust creation, the full legal name and Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) of the grantor or settlor, and the contact details of the acting trustee.
- Prerequisite Knowledge & Standards: Familiarity with Internal Revenue Code guidelines regarding grantor versus non-grantor trusts, understanding the difference between a state-issued tax ID and a federal EIN, and knowing whether the trust will operate under an EIN immediately or use the grantor's SSN during their lifetime.
- Resource & Time Benchmarks: The online application process typically takes roughly 15 to 20 minutes to complete, and the digital EIN is generated instantaneously upon successful validation. There is zero application fee charged by the Internal Revenue Service for this service.
Step-by-Step Procedure to Obtain Your Trust EIN
Step 1: Verify Trust Classification and Legal Authority
Before completing any tax forms, examine the trust document to determine its exact legal structure. Revocable living trusts often use the grantor's Social Security Number for tax reporting while the grantor is alive and competent, meaning they may not require a separate EIN until the grantor passes away or the trust becomes irrevocable. Irrevocable trusts, conversely, almost always require an independent EIN immediately upon creation because they operate as separate taxable entities.
Pro-Tip: Never apply for an EIN for a revocable living trust while the grantor is alive unless the trust is designed to hold specific business assets or real estate that mandates a distinct financial profile.
Step 2: Gather Required Grantor and Trustee Details
Compile all identifying data required by the Internal Revenue Service database. You will need to input the legal name and taxpayer identification number of the responsible party, which for a trust is almost always the acting trustee. If you use a third-party designee, such as a certified public accountant or an estate planning attorney, ensure you have their formal authorization documentation ready.
Warning: Providing an incorrect Social Security Number for the responsible party during the application phase will cause an immediate electronic rejection and flag the application for manual review, delaying trust administration by weeks.
Step 3: Access the Internal Revenue Service Online EIN Assistant
Navigate to the official Internal Revenue Service website and locate the online Employer Identification Number application portal. Select the entity type categorized under trusts, estates, or other fiduciary entities. Read through the preliminary disclosures regarding session timeouts and data security before clicking the button to begin the application.
Step 4: Complete Form SS-4 Electronically
Input the required fields systematically, ensuring that the legal name of the trust matches the nomenclature used on the execution page of the trust agreement. Designate the reason for applying, such as "Created a trust," and provide the physical address of the trust administration office or trustee. Double-check all numerical entries, particularly the Social Security Number of the responsible party, before submitting the final payload.
Step 5: Download and Archive Your Official EIN Confirmation Letter
Upon successful submission, the system will instantly generate a PDF document containing your official nine-digit EIN and confirmation notice, known as Notice CP 575. Download this document immediately, save multiple encrypted backups to secure local storage, and print hard copies to place in the master trust binder for your estate planning records.

Common Filing Failures and Corrective Field Fixes
- Mismatch in Legal Naming Conventions:
- Root Cause: The name entered during the online application differs even slightly from the formal title specified in the trust agreement (e.g., omitting "The" or altering punctuation).
- Actionable Fix: Contact the Internal Revenue Service Business and Specialty Tax Line to amend the trust title on record, or submit a formal letter of explanation signed by the trustee accompanied by the first and signature pages of the trust document.
- Incorrect Responsible Party Designation:
- Root Cause: Listing the trust itself or a deceased grantor as the responsible party instead of the current, living acting trustee.
- Actionable Fix: File Form 8822-B (Change of Address or Responsible Party - Business) to update the Internal Revenue Service database with the correct current trustee's credentials.
- Premature Application for Revocable Entities:
- Root Cause: Obtaining an EIN for a revocable living trust while the grantor is alive, which can trigger conflicting information flags on individual income tax returns.
- Actionable Fix: Send a written closure letter to the Internal Revenue Service office where tax returns are filed, requesting the closure of the specific EIN account while clarifying that the grantor's SSN remains the active identifier.
Frequently Asked Questions
Can a trust use the grantor's Social Security Number instead of an EIN?
Yes, a revocable living trust typically uses the grantor's Social Security Number for all tax reporting purposes during the lifetime of the grantor, provided the grantor is also treated as the owner of the trust under relevant tax codes. Once the grantor passes away or the trust becomes irrevocable, a separate EIN must be obtained.
How much does it cost to get a Tax ID number for a trust?
Obtaining an Employer Identification Number directly through the official Internal Revenue Service online portal is completely free of charge. Beware of third-party websites that charge a fee to submit the application on your behalf, as they provide no official advantage over the direct application process.
How long does it take to receive the Tax ID number?
When you complete the application through the online Internal Revenue Service assistant, the EIN is generated instantaneously upon final submission. If you apply by mail or fax, the processing timeline can extend anywhere from four to six weeks before you receive written confirmation.
Can a foreign national act as a trustee and obtain an EIN for a trust?
Yes, a foreign national can serve as a trustee, but the application process requires specific identifiers. If the responsible party does not possess a Social Security Number or Individual Taxpayer Identification Number, they may need to complete the application process via fax or mail using alternative verification procedures.
What should I do if I misplace the trust's EIN confirmation letter?
If you lose the original Notice CP 575 confirmation letter, you can retrieve the number by checking prior-year fiduciary tax returns, bank account opening documents, or by calling the Internal Revenue Service Business and Specialty Tax Line to request a formal confirmation notice be mailed to the trustee of record.
