The IRS said that the limit on elective deferral contributions to 401(k) plans, 403(b) plans, most 457 plans, and the federal government’s Thrift Savings Plan will increase from $18,500 in 2018 to $19,000 in 2019. However, the catch-up contribution limit for those 50 and older remains $6,000 (Notice 2018-83). Most other inflation-adjusted amounts related to pensions increased from 2018 to 2019.
