Question: what is the maximum contribution to a roth 401k in 2018?
Answer: The maximum amount workers can contribute to a Roth 401(k) for 2019 is $19,000 if they're younger than age 50. That's $500 higher than the 2018 Roth 401(k) contribution limit. Workers age 50 and older can add an extra $6,000 per year in “catch-up” contributions, bringing the total amount to $25,000.
