The creation of the Simplified Employee Pension (SEP) and the Savings Incentive Match Plan for Employees (SIMPLE) affords smaller businesses with a way to offer their employees a retirement plan. The SEP and SIMPLE were designed for businesses with less than 100 employees and y are less costly to administer than a 401(k). For the employees, they are both easy to understand and provide a convenient way to save for retirement.
As qualified retirement plans, SEPs and SIMPLEs enjoy the same tax treatment as other plans. Contributions by employees and employers are tax deductible or made on a pre-tax basis. The accumulation inside the accounts grows tax deferred. The many of the same restrictions apply as well. Withdrawals made prior to age 59 ½ may be subject to a penalty.
As with all defined contribution plans, the future retirement benefit is uncertain as it depends on the amount of contributions, how long they accumulate, and the rate of return on the account over that period of time. At the time of distribution, withdrawals are taxed as ordinary income with no allowance for 10-year averaging as is available through a 401(k).
