Eligibility Requirements
The Individual 401(k) is for incorporated and unincorporated businesses, sole proprietorships, partnerships, and corporations. The only requirement for contributions to this plan is that you receive a salary or wage.
The business entity must have no additional employees other than the spouse of the proprietor—or, in the case of a partnership, the only employees must be self-employed partners and their spouses.
An Individual 401(k) plan must be the only arrangement maintained by the business that is not included as part of a controlled group under federal tax law.
Deadline
The deadline for establishing an Individual 401(k) plan is the last day of your business’s tax year (December 31, for a calendar tax year).
However, if your business is incorporated, you may want to establish an Individual 401(k) plan early in the tax year to make employee salary deferrals based on the Form W-2 income throughout the year.
This is necessary because you may not defer on compensation that is paid to you from your corporation before you establish the Individual 401(k) plan.
