Excerpt: Many of the pension plan limitations will change for 2008 because the increase in the cost-of-living index met the statutory thresholds that trigger their adjustment. However, for others, the limitation will remain unchanged. For example, the limitation under Section 402(g)(1) on the exclusion for elective deferrals described in Section 402(g)(3) remains unchanged at $15,500. This limitation affects elective deferrals to Section 401(k) plans and to the Federal Government's Thrift Savings Plan, among other plans.
