Contribution Limits

Each year the U.S. government adjusts the limits for qualified plans and Social Security to reflect cost-of-living adjustments and changes in the law. Many of these limits are based on the “plan year” as defined in the plan document. The elective deferral and catch-up limits are always based on the calendar year.
