The IRS announced that employee 401(k) contributions for 2019 will top off at $19,000—a $500 increase from 2018—while the “all sources” maximum contribution (employer and employee combined) rises to $56,000. Plan participants who contribute to the limit next year will be able to receive up to $37,000 from a match and profit-sharing contributions ($56,000 minus $19,000). For participants ages 50 and over, the additional “catch-up” contribution limit, which is set by law, will stay at $6,000.
