How To Obtain A Tax ID For A Trust: A Complete Step-by-Step Guide
Securing a federal Employer Identification Number (EIN), commonly known as a tax ID, for a trust is a mandatory legal step required to open bank accounts, file annual fiduciary income tax returns, and issue beneficiary distribution statements. The process is entirely digital for most domestic trusts, requiring accurate legal documentation, valid Social Security or Individual Taxpayer Identification Numbers for responsible parties, and submission through the official Internal Revenue Service online portal.
Trust Setup Requirements & Documentation Checklist
Establishing a valid trust structure requires precise adherence to state probate codes and federal tax classifications. Before initiating the tax ID application, trustees must assemble specific documentation and legal instruments to ensure accurate data entry during the online submission process. Entering conflicting legal names or mismatched grantor details will immediately trigger processing rejections or require manual IRS correspondence.
- Essential Legal Instruments: Executed trust agreement, schedule of trust assets, and any official amendments establishing the trust's existence and naming the acting trustee.
- Responsible Party Identification: Valid Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) for the primary trustee or grantor acting as the designated control party.
- Financial and Operational Benchmarks: Estimated budget of zero dollars for the electronic application process, completed within an estimated duration of fifteen to thirty minutes per entity.
- Prerequisite Knowledge Standards: Clear determination of whether the trust is revocable or irrevocable, as this distinction dictates structural taxation rules and subsequent Form 1041 filing requirements.
How to Apply for and Secure a Trust Tax ID
Step 1: Determine the Proper Trust Classification and Tax Status
Before logging into the government portal, you must identify whether your trust is classified as a grantor trust or a non-grantor trust. Revocable living trusts typically operate as grantor trusts during the lifetime of the trustor, using the trustor's personal SSN for income reporting. However, upon the death of the trustor, a revocable trust becomes irrevocable, creating an independent taxable entity that legally requires its own separate EIN. Irrevocable trusts established during a grantor's life usually require a distinct tax ID immediately upon funding.
Warning: Using a personal SSN for a trust that legally requires a separate EIN can lead to severe IRS compliance penalties, mismatch notices, and complex tax auditing complications.
Step 2: Access the Official IRS EIN Application Portal
Navigate exclusively to the official Internal Revenue Service website to utilize the online EIN Assistant tool. Avoid third-party filing services that charge excessive administrative fees for simple form completion. Ensure your browser is secure and that you are accessing the legitimate federal domain ending in dot gov. The online assistant operates only during specific operational hours established by the IRS, generally Monday through Friday, early morning to late evening Eastern Time.
Step 3: Select the Correct Legal Entity Type
Within the online application interface, select "Trusts" from the primary list of legal structures. The system will subsequently prompt you to narrow down the specific sub-category of the trust. Accurately choose the correct variant matching your legal documents, such as Irrevocable Trust, Charitable Remainder Trust, Testamentary Trust, or Bankruptcy Estate. Misclassifying the trust structure at this stage will invalidate the generated tax ID, forcing you to submit a formal written correction request to the agency.
Step 4: Input the Responsible Party Information
Designate the individual acting as the responsible party for the trust. For most standard trusts, this is the current serving trustee. The system requires the full legal name and the valid SSN or ITIN of this individual. The IRS defines the responsible party as the person who exercises ultimate operational or financial control over the entity.
Pro-Tip: The individual listed as the responsible party must pass identity verification protocols within the online portal; ensure their legal name matches their social security card precisely.
Step 5: Complete the Trust Details and Download the Official Notice
Fill in the remaining mandatory fields, including the legal name of the trust as stated in the trust document, the physical mailing address, the state or foreign country where the trust was formed, and the exact date the trust was funded or acquired. Review all entered data on the final summary screen for typographical errors. Upon final electronic submission, the system will instantly generate an official EIN confirmation letter (Notice CP 575 or equivalent document). Download and save this PDF file immediately, as it serves as the official proof of your trust tax ID.

Common Trust Tax ID Application Failures and Field Fixes

Frequently Asked Questions
Can a revocable living trust use the grantor's Social Security Number?
Yes, during the lifetime of the grantor, a revocable living trust is typically treated as a grantor trust for federal income tax purposes. This means all income, deductions, and credits are reported directly on the grantor's personal individual income tax return using their personal SSN. However, once the grantor passes away, the trust becomes irrevocable, and a separate EIN must be obtained.
How long does it take to get a tax ID for a trust online?
When utilizing the official online IRS EIN Assistant tool, the process takes approximately fifteen minutes from start to finish. Upon completing the final validation steps, the system issues the official PDF confirmation letter containing the tax ID immediately on the screen, allowing you to print or save it right away.
What should I do if I lose the official EIN confirmation letter?
If you misplace your official IRS confirmation letter containing the trust tax ID, you can retrieve it by contacting the IRS Business and Specialty Tax Line directly. Alternatively, you can review past bank statements, prior year fiduciary tax returns (Form 1041), or official IRS correspondence addressed to the trust where the nine-digit number is printed.
Do I need a lawyer to obtain a tax ID for a trust?
Legal representation is not required to apply for and obtain an EIN for a trust. Any authorized trustee or designated legal representative can complete the online application independently. However, consulting an estate planning attorney or certified public accountant is strongly recommended to ensure proper trust classification and long-term tax compliance.
Can a foreign trust obtain a United States tax ID?
Yes, foreign trusts that hold United States source income, engage in trade or business within the United States, or have U.S. beneficiaries receiving distributions may apply for an EIN. Foreign entities can complete the application process by telephone, fax, or mail using specialized IRS forms if they do not possess a standard U.S. social security number for a responsible party.
