If you have misplaced the employer identification number (EIN) for your solo 401k trust and the title company is asking to list it on the W-9 at time of property purchase or sale, try calling the bank where you opened the solo 401k bank account as they would have used it to open the solo 401k bank account. If they can’t timely provide it, you can call the IRS directly to obtain it.
Ask the IRS to search for your EIN by calling the Business & Specialty Tax Line at (800) 829-4933. The hours of operation are 7:00 a.m. – 7:00 p.m. local time, Monday through Friday. An assistor will ask you for identifying information and provide the number to you over the telephone, as long as you are a person who is authorized to receive it. Examples of an authorized person include, but are not limited to, a sole proprietor, a partner in a partnership, a corporate officer, a trustee of a trust, or an executor of an estate.
