Participants may contribute up to $18,000 in 2017.
Age 50 Catch Up
Participants age 50 and older at any time during the calendar year are permitted to contribute an additional $6,000 in 2017.
Employees with 15 years of service with their current employer and an annual average contribution of less than $5,000 per year are eligible for an additional $3,000 contribution per year up to a lifetime maximum catch up of $15,000. This is known as the 15-year rule. For participants eligible for both the age 50 catch up and the 15-year rule, the IRS will apply contributions above the regular limit first to the 15-year rule. Employers are not required to make this provision available.
