FAQs About Individual 401(k) Plans
Owner-only businesses including partnerships now have a greater opportunity to benefit from both the salary deferral and employer contribution features of a 401(k) plan. Because of tax law changes under the Economic Growth and Tax Relief Reconciliation Act of 2001 (EGTRRA), employers may be able to contribute more to the plan on a tax-deferred basis than previously allowed. And because the Individual 401(k) is only for owners and their spouse and partners and their spouses, you avoid the costly administrative burden of a traditional 401(k) plan.

What are the features of an Individual 401(k)?
- Self-directed investment account
- Up to $46,000 in contributions for 2008[1] ($46,000[2] + $5,000[3] catch-up deferral for owners age 50 or older)

Who should open an Individual 401(k)?
The Individual 401(k) is designed for owner-only businesses looking to save more for retirement than previously possible with a traditional small business retirement plan.
The plan maximizes contributions for a sole proprietor or partnerships with earned income of less than $230,000[1]. Individuals with income greater than this level can usually make the maximum contribution of $46,000[2] without using the salary deferral feature.
- [1] $230,000 is the annual compensation cap for 2008. Future indexing is in $5,000 increments.
- [2] $46,000 is the annual contribution limit for 2008. Future indexing is in $1,000 increments.
- [3] $5,000 is the annual catch-up contribution limit for 2008.

Note: This chart is for demonstration purposes only. Actual contribution amounts may vary.
Note: A spouse employee and partners and their spouses may be included; however, the Individual 401(k) plan does not support accounts for common law employees. For businesses that include common law employees or less than 5% owners, please ask about other products that are suitable for you.
Are there advantages of an Individual 401(k) over a standard Profit Sharing or Money Purchase Pension plan?
Yes. Because of the law changes made by EGTRRA, an employer can now take a full deduction for elective deferrals in addition to the maximum 25% deduction allowed for a profit sharing contribution. Please note, however, that your total contribution per individual, including deferrals, cannot exceed the lesser of 100% of compensation or $46,000[2] annually. (If you are age 50 or older, an additional $5,000[3] catch-up deferral is allowed.)
Can I establish an Individual 401(k) if my business has employees?
No. The only other employee that may be included in the Individual 401(k) besides the business owner is the owner's spouse, partners, and partner's spouse. If the business employs additional employees, the business will be required to transition to a traditional 401(k) (or other type of plan). This is due to the additional administrative burden brought on by additional participants. If you find yourself in this situation, please contact us at 800.209.9010 to find out about other products that are available to you.
What is the deadline for depositing salary deferral contributions?
The Department of Labor (DOL) regulations state that salary deferral contributions are to be made as of the earliest date on which such contributions can reasonably by segregated from the employer's general assets (CFR 2510.3-102). In general, salary deferral contributions are calculated upon the determination of the participants' compensation/earned income using the participants' salary deferral agreement. Please contact your tax or legal advisor with questions specific to how and when your compensation or earned income is determined.
Can I take a loan from an Individual 401(k)?
Yes. Loans are available with our Individual 401(k) plan.
Can I also make contributions to an IRA or a Roth IRA?
Yes. A small business owner who elects to open an Individual 401(k) plan may also contribute the maximum dollar amount allowable under current law to an IRA or Roth IRA. However, contributions may not be deductible.
