WASHINGTON — The Internal Revenue Service today announced cost of living adjustments applicable to dollar limitations for pension plans and other items for tax year 2009.

Section 415 of the Internal Revenue Code provides for dollar limitations on benefits and contributions under qualified retirement plans. It also requires that the Commissioner annually adjust these limits for cost of living increases.

Many of the pension plan limitations will change for 2009 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) is increased from $15,500 to $16,500. This limitation affects elective deferrals to Section 401(k) plans and to the federal government’s Thrift Savings Plan, among other plans.

Effective Jan. 1, 2009, the limitation on the annual benefit under a defined benefit plan under Section 415(b)(1)(A) is increased from $185,000 to $195,000. For participants who separated from service before Jan. 1, 2009, the limitation for defined benefit plans under Section 415(b)(1)(B) is computed by multiplying the participant's compensation limitation, as adjusted through 2008, by 1.0530. The limitation for defined contribution plans under Section 415(c)(1)(A) is increased from $46,000 to $49,000.

The Code provides that various other dollar amounts are to be adjusted at the same time and in the same manner as the dollar limitation of Section 415(b)(1)(A).

Social Security and Supplemental Security Income benefits increase automatically each year based on 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. This year's increase in the CPI-W was 5.8 percent. The 5.8 percent Cost-of-Living Adjustment (COLA) will begin with benefits that over 50 million Social Security beneficiaries receive in January 2009. Increased payments to more than 7 million Supplemental Security Income beneficiaries will begin on December 31.

Some other changes that take effect in January of each year are based on the increase in average wages. Based on that increase, the maximum amount of earnings subject to the Social Security tax (taxable maximum) will increase to $106,800 from $102,000. Of the estimated 164 million workers who will pay Social Security taxes in 2009, about 11 million will pay higher taxes as a result of the increase in the taxable maximum.
