Does a Solo 401k Need an Ein

An Employer Identification Number (EIN) is not typically required for a solo 401(k) plan, which is a retirement savings plan for self-employed individuals with no employees. However, an EIN may be necessary if you are operating a business as a corporation or other legal entity separate from yourself. The IRS recommends obtaining an EIN for any solo 401(k) plan that is established under a business name. This is because the EIN helps identify the plan and simplifies the reporting process, ensuring that contributions and distributions are properly tracked and taxed.
