Roth 401(k) KnowledgebaseDeferral Limits and Eligibility RequirementsIndividual Pre-tax and Roth 401(k) Contribution Limits
No AGI Limit for Eligibility The adjusted gross income limits (AGI) that apply to Roth IRAs, do not apply to Roth 401(k)s. Therefore, if the employer's plan offers this feature, all eligible plan participants can contribute to a Roth 401(k). Individual Calendar Year Limit The 401(k) individual contribution limit for calendar year 2008 is $15,500. Participants who are or become age 50 in calendar year 2008, may contribute an additional “catch-up” contribution up to $5,000. These limits apply to the all 401(k) contributions, whether they are Roth, pre-tax, or a combination of Roth and pre-tax. COLAs (cost-of-living adjustments) After 2006, the individual 401(k) and catch-up limits increase based on the annual COLA in minimum increments of $500.
*Limits shown for 2009-2012 are estimated based on historical increases. In general, the annual COLA is calculated by comparing the rise in the Bureau of Labor Statistics’ Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of the prior year to the corresponding period of the current year. Not a Plan Limit The individual 401(k) and catch-up contribution calendar year limits apply to the total of all contributions in all 401(k) plans in which one participates, whether the employers are unrelated or considered related. This means that an individual may participate in two or more separate plans of two or more employers; however, the total of all contributions to all of these plans may not exceed the individual 401(k) and catch-up calendar year limits.
