IRS boosts maximum 401(k) contribution to $17,000

WASHINGTON (AP) ? The Internal Revenue Service is boosting the maximum contribution that workers can make to their 401(k) pension plans without paying upfront taxes. The limit will rise to $17,000 next year.

The increase, required by law to adjust for inflation, is $500 higher than this year’s level. The ceiling hadn’t grown since 2009 because inflation had been too low to trigger an increase.

Companies that set up 401(k) plans for their employees are free to limit maximum contributions at levels below the legal ceiling, and many do.

Thirty-three percent of workers aged 21-64 used 401(k) plans in 2009, the most recent year for which figures are available. That’s according to the Employee Benefit Research Institute, a non-partisan research group that advocates strong employee benefit programs.
