Tax time anxiety starts on January 1 and grows toward full-blown panic as April 15 approaches. It's bad enough if all you need to do is fill out a personal 1040; it's even worse if you're responsible for filing taxes for a trust--and you can't find its tax ID number to save your life! But take heart. Employer ID Numbers are easy to retrieve. Your best option depends on how you applied for your trust's EIN and what you've done with it since.
Refer to the computer-generated notice the IRS issued to you immediately after you completed the online application process for your trust's Employer ID Number (EIN). This notice will contain your trust's EIN.
Contact the bank where you used your trust's EIN to open an account, or any state or local agency with whom you used your trust's EIN to apply for a license.
Contact the IRS via the Business & Specialty Tax Line: (800) 829-4933. Call between 7:00 a.m. and 10:00 p.m. local time, Monday through Friday. A representative will request some identifying information in order to look up your trust's EIN and confirm that you are authorized to receive it. If you do not have the authority to be told the EIN, the IRS will send the EIN via postal mail to the taxpayer listed on the original application.
