401(k) retirement plan contribution limit increases for 2018; most other limits are stagnant

401(k) retirement plan contribution limit increases for 2018; most other limits are stagnantRetirement plan contribution limits are indexed for inflation, but with inflation remaining low, most of the limits remain unchanged for 2018. But one piece of good news for taxpayers who’re already maxing out their contributions is that the 401(k) limit has gone up by $500. The only other limit that has increased from the 2017 level is for contributions to defined contribution plans, which has gone up by $1,000.
