Sole prop solo 401k start up; EIN required or SSN allowed

[Santo Gold]

Simple enough, an individual who does significant work for herself but does not have a separate business name/EIN.  She wants to start a 401k with her SS#.   Is this permitted?

Thanks

Need an EIN. Do not use a SSN.

From the instructions to 5500-EZ

Quote

Line 2b. Enter the employer’s nine-digit employer identification number (EIN). For example, 00-1234567. Do not enter a social security number (SSN).

Employers without an EIN must apply for one as soon as possible. EINs are issued by the IRS. You can apply for an EIN:

• Online — Go to the IRS website at IRS.gov/Businesses and click on “Employer ID Numbers.” The EIN is issued immediately once the application information is validated.

• By mailing or faxing Form SS-4, Application for Employer Identification Number.

You can file an SS4 on line and get EIN almost immediately.
