Posted by Madison on November 5, 2014. The 2015 Roth IRA limits and Roth 401k contribution limits were just announced, so you can start planning your contributions. The 2015 limits will stay the same for the Roth IRA; the Roth 401k limits will increase.The 401k limits and IRA limits are determined based on inflation, but can only increase in $500 increments. highlight the Roth IRA and the Roth 401k because they are my favorite retirement plans; the limits for traditional 401ks and IRAs are the same as the Roth 401k and Roth IRAs.
