How To Get A Tax ID Number For A Trust
Securing a Tax ID number, formally known as an Employer Identification Number (EIN), is a mandatory legal step for any newly established trust that generates income, hires employees, or requires a separate financial identity from the grantor. The process involves submitting IRS Form SS-4 through official federal channels, with instant digital issuance available via the online portal during standard operating hours.
Preparing to Apply for a Trust EIN
Establishing a trust requires meticulous documentation before you interact with federal revenue agencies. The Internal Revenue Service (IRS) mandates specific data points regarding the trust instrument, the legal creator, and the fiduciary administering the estate. Failing to gather these credentials beforehand results in processing delays or application rejections.
- Essential Documentation & Information: A finalized and signed trust agreement, the exact legal name of the trust, the date of trust formation, and the physical address of the administration office.
- Mandatory Prerequisite Knowledge: Identification of the trust type (revocable versus irrevocable), determination of whether the trust requires a separate tax return (Form 1041), and validation of the grantor or trustee Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
- Time and Financial Benchmarks: The online application is entirely free of charge and takes approximately 10 to 15 minutes to complete, yielding an immediate digital EIN PDF upon successful submission.
Step-by-Step Guide to Securing Your Trust Tax ID
Step 1: Classify the Trust Structure
Before launching the application portal, determine the exact legal classification of your trust. Revocable living trusts typically use the grantor's SSN during the grantor's lifetime and do not require a separate EIN until the grantor passes away or the trust becomes irrevocable. Irrevocable trusts, charitable trusts, and testamentary trusts require an independent EIN immediately upon creation because they are treated as separate taxable entities by the federal government.
Pro-Tip: Review the trust document carefully or consult an estate planning attorney to confirm whether the trust is a grantor trust or a non-grantor trust, as this dictates how income is reported on federal tax returns.
Step 2: Gather Responsible Party Credentials
The IRS requires every trust EIN application to name a "Responsible Party." For a trust, this is almost always the acting trustee or the grantor if it is a revocable arrangement. You must supply the full legal name and valid SSN or ITIN of this individual. The IRS uses this information to verify identity and track tax compliance.
Warning: Never use a third-party accountant or attorney’s personal identification details as the responsible party; the system demands the actual controlling fiduciary of the trust estate.
Step 3: Access the Official IRS Online Application Portal
Navigate to the official IRS website and locate the Apply for an Employer Identification Number (EIN) Online tool. Ensure you are using the official government domain (.gov) to avoid fraudulent third-party filing services that charge unnecessary fees for a free government service. The online assistant is accessible Monday through Friday during standard business hours and provides the EIN immediately upon completion.
Step 4: Complete Form SS-4 Prompts
The digital interview will guide you through a series of dropdown menus and text fields corresponding to IRS Form SS-4. Select "Trusts" as the legal structure type, input the exact legal name of the trust, provide the state where the trust was formed, and enter the trustee's personal identification details. Double-check all spellings and numerical entries against your executed trust agreement to prevent discrepancies.
Step 5: Validate and Download Your EIN Confirmation Letter
Upon final submission, the system validates your entries and generates an official IRS EIN assignment notice, known as Notice CP 575. Save this document digitally and print physical copies for your records. Banks, financial institutions, and investment brokerages will require this exact document to open trust checking, savings, or investment accounts.

Troubleshooting Common Trust EIN Application Failures
- System Rejection Due to Name Mismatch:
- Root Cause: The legal name entered into the IRS portal does not match the exact wording in the trust document, or illegal characters were used.
- Actionable Fix: Review the trust agreement's first page, remove any punctuation marks like periods or ampersands that the IRS system rejects, and re-enter the name precisely as written.
- Responsible Party Verification Error:
- Root Cause: The SSN provided for the trustee does not match government database records, often due to a recent legal name change or typographical error.
- Actionable Fix: Verify the SSN against the trustee's social security card, ensure the name matches tax records, and attempt the electronic application again or file via mail using paper Form SS-4.
- Obtaining a Duplicate EIN Notice:
- Root Cause: The original Notice CP 575 containing the EIN was misplaced before opening the trust bank account.
- Actionable Fix: Contact the IRS Business and Specialty Tax Line to request a confirmation letter, or submit Form 4506-T to request a formal verification letter.
Frequently Asked Questions
Can I use my personal SSN for a trust bank account?
You can only use a personal Social Security Number if you have established a revocable living trust where you act as the grantor, trustee, and primary beneficiary during your lifetime. Once the trust becomes irrevocable or the grantor passes away, federal law strictly requires a dedicated EIN.
Is there a fee to get a Tax ID number for a trust?
No. The IRS provides EINs completely free of charge through its official online portal. Any website demanding payment to secure an EIN for your trust is a private third-party filing service and should be avoided.
What should I do if I make a mistake on my trust EIN application?
If you submitted the online application and realized a minor error in the trust name or address, you do not need to reapply. You can submit a written correction letter to the IRS office servicing your state, detailing the correct trust information and referencing your assigned EIN.
Can a foreign trust get a US Tax ID number?
Yes. If a foreign trust generates income from United States sources or is required to file a US federal tax return, it can apply for an EIN. International applicants generally submit paper Form SS-4 via fax or mail rather than using the online digital portal.
How long does it take to get a trust EIN?
If you use the official IRS online application tool, the EIN is generated instantly upon final submission, allowing you to download the official assignment letter immediately. If you apply via fax or mail, the processing time can take anywhere from two to four weeks.
