Once you have established a 401(k) plan, you assume certain responsibilities in operating the plan. If you hired someone to help in setting up your plan, that arrangement also may have included help in operating the plan. If not, another important decision will be whether to manage the plan yourself or to hire a professional or financial institution - such as a bank, mutual fund provider, or insurance company - to take care of some or most aspects of operating the plan. Elements of a plan that need to be handled include:
- Investing 401(k) monies
- Fiduciary responsibilities
- Disclosing plan information to participants
- Reporting to government agencies
- Distributing plan benefits
Typically, a plan includes a mix of rank-and-file employees and owner/managers. However, some employees may be excluded from a 401(k) plan if they:
- Have not attained age 21;
- Have not completed a year of service; or
- Are covered by a collective bargaining agreement that does not provide for participation in the plan, if retirement benefits were the subject of good faith bargaining.
Employees cannot be excluded from a plan merely because they are older workers.
Another design option you will have in establishing and operating a 401(k) plan is deciding on your business’s contribution (if any) to participants’ accounts in the plan.
Traditional 401(k) plan
If you decide to contribute to your 401(k) plan, you have further options. You can contribute a percentage of each employee’s compensation to the employee’s account (called a nonelective contribution), or you can match the amount your employees decide to contribute (within the limits of current law) or you can do both.
For example, you may decide to add a percentage - say 50 percent - to an employee’s contribution, which results in a 50-cent increase for every dollar the employee sets aside. Using a matching contribution formula will provide additional employer contributions only to employees who make deferrals to the 401(k) plan. If you choose to make nonelective contributions, the employer makes a contribution for each eligible participant, whether or not the participant decides to make a salary deferral to his or her 401(k) account.
Under a traditional 401(k) plan, you have the flexibility of changing the amount of nonelective contributions each year, according to business conditions.
Safe Harbor 401(k) plan
Under a safe harbor plan, you can match each eligible employee’s contribution, dollar-for-dollar, up to 3 percent of the employee’s compensation, and 50 cents on the dollar for the employee’s contribution that exceeds 3 percent, but not 5 percent, of the employee’s compensation. Alternatively, you can make a nonelective contribution equal to 3 percent of compensation to each eligible employee’s account. Each year you must make either the matching contributions or the nonelective contributions.
Automatic Enrollment 401(k)
Under an automatic enrollment 401(k) plan with a qualified automatic contribution arrangement, the plan is exempt from the annual IRS testing requirement that a traditional 401(k) plan must perform. The initial automatic employee contribution must be at least 3 percent of compensation. Contributions may have to automatically increase so that, by the fifth year, the automatic employee contribution is at least 6 percent of compensation.
The automatic employee contributions cannot exceed 10 percent of compensation in any year. The employee is permitted to change the amount of his or her employee contributions or choose not to contribute but must do so by making an affirmative election.
The employer must make at least either:
- A matching contribution of 100 percent for salary deferrals up to 1 percent of compensation and a 50 percent match for all salary deferrals above 1 percent but no more than 6 percent of compensation; or
- A nonelective contribution of 3 percent of compensation to all participants
SIMPLE 401(k) plan
Employer contributions to a SIMPLE 401(k) plan are limited to either:
1. A dollar-for-dollar matching contribution, up to 3 percent of pay; or
2. A nonelective contribution of 2 percent of pay for each eligible employee.
No other employer contributions can be made to a SIMPLE 401(k) plan, and employees cannot participate in any other retirement plan of the employer.
The maximum amount that employees can contribute to their SIMPLE 401(k) accounts is $12,500 in 2015, 2016, 2017, and 2018. See annual cost-of-living updates for more information.
An additional catch-up contribution is allowed for employees aged 50 and over. The additional contribution amount is $3,000 in 2015, 2016, 2017, and 2018.
Total employer and employee contributions to all of an employer’s plans are subject to an overall annual limitation - the lesser of:
- 100 percent of the employee’s compensation, or
- $55,000 (for 2018; $54,000 for 2017; $53,000 for 2015 and 2016).
The amount employees can contribute under a traditional, safe harbor or automatic enrollment 401(k) plan is limited to $18,500 in 2018 ($18,000 in 2015, 2016, and 2017).
Traditional, safe harbor and automatic enrollment 401(k) plans can allow additional catch-up contributions in the amount of $6,000 in 2015, 2016, 2017, and 2018 for employees aged 50 and over.
Employee salary deferrals are immediately 100 percent vested - that is, the money that an employee has put aside through salary deferrals cannot be forfeited. When an employee leaves employment, he/she is entitled to those deferrals, plus any investment gains (or minus losses) on their deferrals.
In SIMPLE 401(k) plans and safe harbor 401(k) plans, all required employer contributions are always 100 percent vested.
In traditional 401(k) plans, you can design your plan so that employer contributions become vested over time, according to a vesting schedule.
Realizing 401(k) plan tax benefits requires that plans provide substantive benefits for rank-and-file employees, not only for business owners and managers. These requirements are referred to as nondiscrimination rules and cover the level of plan benefits for rank-and-file employees compared to owners/managers.
Traditional 401(k) plans are subject to annual testing to assure that the amount of contributions made on behalf of rank-and-file employees is proportional to contributions made on behalf of owners and managers. Safe harbor 401(k) plans and SIMPLE 401(k) plans are not subject to annual nondiscrimination testing.
Investing 401(k) Monies
After you decide on the type of 401(k) plan, you can consider the variety of investment options. One decision you will need to make in designing a plan is whether to permit your employees to direct the investment of their accounts or to manage the monies on their behalf. If you choose the former, you also need to decide what investment options to make available to the participants. Depending on the plan design you choose, you may want to hire someone either to determine the investment options to make available or to manage the plan’s investments. Continually monitoring the investment options ensures that your selections remain in the best interests of your plan and its participants.
Disclosing Plan Information To Participants
Plan disclosure documents keep participants informed about the basics of plan operation, alert them to changes in the plan’s structure and operations, and provide them a chance to make decisions and take timely action with respect to their accounts.
The summary plan description (SPD) - the basic descriptive document - is a plain-language explanation of the plan and must be comprehensive enough to apprise participants of their rights and responsibilities under the plan. It also informs participants about the plan features and what to expect of the plan. Among other things, the SPD must include information about:
- When and how employees become eligible to participate in the 401(k) plan;
- The contributions to the plan;
- How long it takes to become vested;
- When employees are eligible to receive their benefits;
- How to file a claim for those benefits; and
- Basic rights and responsibilities participants have under the Federal retirement law, the Employee Retirement Income Security Act (ERISA).
The SPD should include an explanation about the administrative expenses that will be paid by the plan. This document must be given to participants when they join the plan and to beneficiaries when they first receive benefits. SPDs must also be redistributed periodically during the life of the plan.
A summary of material modification (SMM) apprises participants of changes made to the plan or to the information required to be in the SPD. The SMM or an updated SPD must be automatically furnished to participants within a specified number of days after the change.
An individual benefit statement (IBS) shows the total plan benefits earned by a participant, vested benefits, the value of each investment in the account, information describing the ability to direct investments, and (for plans with participant-direction) an explanation of the importance of a diversified portfolio. Plans that provide for participant directed accounts must furnish individual account statements on a quarterly basis. Plans that do not provide for participant direction must furnish statements annually.
A summary annual report (SAR) is a narrative of the plan’s annual return/report, the Form 5500, filed with the Federal government (see Reporting to Government Agencies for more information). It must be furnished annually to participants.
A blackout period notice gives employees advance notice when a blackout period occurs, typically when plans change recordkeepers or investment options, or when plans add participants due to corporate mergers or acquisitions. During a blackout period, participants’ rights to direct investments, take loans, or obtain distributions are suspended.
Reporting To Government Agencies
In addition to the disclosure documents that provide information to participants, plans must also report certain information to government entities.
Form 5500 series
Plans are required to file an annual return/report with the Federal government. Depending on the number and type of participants covered, most 401(k) plans must file one of the two following forms:
For 401(k) plans, the Form 5500 is designed to disclose information about the plan and its operation to the IRS, the U.S. Department of Labor, plan participants, and the public.
Most one-participant plans (sole proprietor and partnership plans) with total assets of $250,000 or less are exempt from the annual filing requirement. A final return/report must be filed when a plan is terminated regardless of the value of the plan’s assets.
Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc. is given to both the IRS and recipients of distributions from the plan during the year. It is used to report distributions (including rollovers) from a retirement plan
Distributing Plan Benefits
Benefits in a 401(k) plan are dependent on a participant’s account balance at the time of distribution.
When participants are eligible to receive a distribution, they typically can elect to:
- Take a lump sum distribution of their account,
- Roll over their account to an IRA or another employer’s retirement plan, or
- Purchase an annuity.
Even with the best intentions, mistakes in plan operation can still happen. The U.S. Department of Labor and IRS have correction programs to help 401(k) plan sponsors correct plan errors, protect participants, and keep plan's tax benefits. These programs are structured to encourage you to correct the errors early. Having an ongoing review program makes it easier to spot and correct mistakes in plan operations.
