401(k) plan

The 401(k) plan (technically, a qualified profit-sharing plan with a cash or deferred feature) has become a hugely popular retirement savings vehicle for small businesses. According to the Department of Labor, an estimated 60 million American workers are enrolled in 401(k) plans with total assets of about 3 trillion dollars. With a 401(k) plan, employees can make pretax and/or Roth contributions in 2012 of up to $17,000 of pay ($22,500 if age 50 or older). These deferrals go into a separate account for each employee and aren't taxed until distributed. Generally, each employee with a year of service must be allowed to contribute to the plan.

You can also make employer contributions to your 401(k) plan--either matching contributions or discretionary profit-sharing contributions. Combined employer and employee contributions for any employee in 2012 can't exceed the lesser of $50,000 (plus catch-up contributions of up to $5,500 if your employee is age 50 or older) or 100% of the employee's compensation. In general, each employee with a year of service is eligible to receive employer contributions, but you can require two years of service if your contributions are immediately vested.

401(k) plans are required to perform somewhat complicated testing each year to make sure benefits aren't disproportionately weighted toward higher paid employees. However, you don't have to perform discrimination testing if you adopt a "safe harbor" 401(k) plan. With a safe harbor 401(k) plan, you generally have to either match your employees' contributions (100% of employee deferrals up to 3% of compensation, and 50% of deferrals between 3 and 5% of compensation), or make a fixed contribution of 3% of compensation for all eligible employees, regardless of whether they contribute to the plan. Your contributions must be fully vested.

Another way to avoid discrimination testing is by adopting a SIMPLE 401(k) plan. These plans are similar to SIMPLE IRAs, but can also allow loans and Roth contributions. Because they're still qualified plans (and therefore more complicated than SIMPLE IRAs), and allow less deferrals than traditional 401(k)s, SIMPLE 401(k)s haven't become popular.

Defined benefit plan

A defined benefit plan is a qualified retirement plan that guarantees your employees a specified level of benefits at retirement (for example, an annual benefit equal to 30% of final average pay). As the name suggests, it's the retirement benefit that's defined, not the level of contributions to the plan. In 2012, a defined benefit plan can provide an annual benefit of up to $200,000 (or 100% of pay if less). The services of an actuary are generally needed to determine the annual contributions that you must make to the plan to fund the promised benefit. Your contributions may vary from year to year, depending on the performance of plan investments and other factors.

In general, defined benefit plans are too costly and too complex for most small businesses. However, because they can provide the largest benefit of any retirement plan, and therefore allow the largest deductible employer contribution, defined benefit plans can be attractive to businesses that have a small group of highly compensated owners who are seeking to contribute as much money as possible on a tax-deferred basis.

As an employer, you have an important role to play in helping America's workers save. Now is the time to look into retirement plan programs for you and your employees.
