Salary reduction simplified employee pension plans (SARSEPs) are a type of pension plan that, as of 1997, are no longer available. Those who already have such plans can continue to contribute to them, and add accounts for new employees, but no new SARSEPs can be set up.
SARSEPs are SEPs that act like 401(k) plans in the sense that employees who participate in the SARSEP can elect to have salary-reduction contributions made to the SEP, just as they can in a 401(k) plan.
Basic rules. The amount that can be deferred in a SARSEP is $17,500 for 2013 ($17,000 for 2012; this amount may be adjusted for inflation) or 100 percent of compensation, whichever is less. To participate, an employee must be at least 21, must have worked for you in at least three of the preceding five years, and must have received at least $550 in compensation for the year in which the contribution was made. The compensation amount may be adjusted annually for inflation. The election to use a SARSEP is available only if (1) at least 50 percent of the employees who are eligible to participate elect to have amounts contributed to the SEP and (2) you have no more than 25 eligible employees.
