What Are the SIMPLE IRA Contribution Limits?

Employees may contribute a maximum $12,500 to SIMPLE IRA plans in the year 2015, according to the IRS. Catch-up contributions up to $3,000 may be made by participants 50 years of age and older, if permitted by the SIMPLE IRA plan.

Employee participating in other employer plans with elective salary reductions under them are limited to total salary reductions of $18,000 across all plans in 2015, according to the IRS. Unless they decide to make non-elective contributions of two percent, employers are generally required to make matching contributions on a dollar-for-dollar basis up to three percent of the employee's compensation.
