The IRS requires an Employer Identification Number (EIN) for sole proprietors who establish a retirement plan.
Generally, a sole proprietor who (1) has no employees and (2) doesn't file any excise or pension plan tax returns doesn't need an EIN. In this instance, a Social Security Number (SSN) may be used as the Taxpayer Identification Number (TIN).
However, an EIN is required when a sole proprietor creates a retirement savings plan.
The fastest and easiest way to apply for an EIN is via the EIN Assistant directly on the IRS website. An EIN will be issued immediately so you can complete your retirement plan set-up request.
A few tips before you proceed:
- You must have a valid Taxpayer Identification Number (SSN, ITIN, EIN). Your EIN will not be linked to your SSN.
- Your application must be filled out in one session and cannot be saved.
- The session will time-out after 15 minutes if not in use. You may apply only once per day.
- You will immediately get an EIN after the form is completed.
