A tax ID number, also known as an employer identification number (EIN), is a nine-digit number distributed by the IRS to identify sole proprietors, partnerships, corporations, estates and trusts for tax reporting purposes. Generally, the IRS does not require the grantor of an estate, or the individual who owns the assets in the trust, to obtain an EIN number; however, if someone other than the grantor is acting as the trustee, the trust must obtain an EIN. This number is used to report investments and prepare federal and state income tax, rather than using the grantor’s Social Security number. To obtain an EIN number for a trust, you must complete Form SS-4 and submit the form to the IRS.
Visit the IRS website at IRS.gov and obtain Form SS-4 and the corresponding instructions. You can save the form and instructions to your computer or print the documents directly from the website.
Enter your information in the top portion of the form. You must also provide information about the trustee.
Check the box labeled “Trust,” and enter the grantor’s Taxpayer Identification Number (TIN) in the field provided. Generally, this number is the grantor’s Social Security number or individual taxpayer identification number (ITIN).
Complete the remainder of the form, only answering the questions that are relevant to the trust.
Sign and date Form SS-4. Mail the form to the IRS address listed on the Form SS-A instructions.
Visit the IRS website at IRS.gov and click the “Apply for an EIN Online” link. This link is located toward the top of the page.

Click “Continue." The IRS will display the trust’s EIN number.
