PHOENIX - - The Internal Revenue Service today announced cost‑of‑living adjustments affecting dollar limitations for pension plans and other retirement-related items for Tax Year 2013. In general, many of the pension plan limitations will change for 2013 because the increase in the cost-of-living index met the statutory thresholds that trigger their adjustment. However, other limitations will remain unchanged because the increase in the index did not meet the statutory thresholds that trigger their adjustment. Highlights include:

* The elective deferral (contribution) limit for employees who participate in 401(k), 403(b), most 457 plans, and the federal government's Thrift Savings Plan is increased from $17,000 to $17,500.

* The catch-up contribution limit for employees aged 50 and over who participate in 401(k), 403(b), most 457 plans, and the federal government's Thrift Savings Plan remains unchanged at $5,500.

* The deduction for taxpayers making contributions to a traditional IRA is phased out for singles and heads of household who are covered by a workplace retirement plan and have modified adjusted gross incomes (AGI) between $59,000 and $69,000, up from $58,000 and $68,000 in 2012. For married couples filing jointly, in which the spouse who makes the IRA contribution is covered by a workplace retirement plan, the income phase-out range is $95,000 to $115,000, up from $92,000 to $112,000. For an IRA contributor who is not covered by a workplace retirement plan and is married to someone who is covered, the deduction is phased out if the couple's income is between $178,000 and $188,000, up from $173,000 and $183,000.

* The AGI phase-out range for taxpayers making contributions to a Roth IRA is $178,000 to $188,000 for married couples filing jointly, up from $173,000 to $183,000 in 2012. For singles and heads of household, the income phase-out range is $112,000 to $127,000, up from $110,000 to $125,000. For a married individual filing a separate return who is covered by a retirement plan at work, the phase-out range remains $0 to $10,000.

* The AGI limit for the saver's credit (also known as the retirement savings contribution credit) for low- and moderate-income workers is $59,000 for married couples filing jointly, up from $57,500 in 2012; $44,250 for heads of household, up from $43,125; and $29,500 for married individuals filing separately and for singles, up from $28,750.

Below are details on both the unchanged and adjusted limitations.

Section 415 of the Internal Revenue Code provides for dollar limitations on benefits and contributions under qualified retirement plans. Section 415(d) requires that the Commissioner annually adjust these limits for cost‑of‑living increases. Other limitations applicable to deferred compensation plans are also affected by these adjustments under Section 415. Under Section 415(d), the adjustments are to be made pursuant to adjustment procedures which are similar to those used to adjust benefit amounts under Section 215(i)(2)(A) of the Social Security Act.

The limitations that are adjusted by reference to Section 415(d) generally will change for 2013 because the increase in the cost-of-living index met the statutory thresholds that trigger their adjustment. For example, the limitation under Section 402(g)(1) on the exclusion for elective deferrals described in Section 402(g)(3) is increased from $17,000 to $17,500 for 2013. This limitation affects elective deferrals to Section 401(k) plans, Section 403(b) plans, and the Federal Government's Thrift Savings Plan.

Effective January 1, 2013, the limitation on the annual benefit under a defined benefit plan under Section 415(b)(1)(A) is increased from $200,000 to $205,000. For a participant who separated from service before January 1, 2013, the limitation for defined benefit plans under Section 415(b)(1)(B) is computed by multiplying the participant's compensation limitation, as adjusted through 2012, by 1.0170.

The limitation for defined contribution plans under Section 415(c)(1)(A) is increased in 2013 from $50,000 to $51,000.

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). After taking into account the applicable rounding rules, the amounts for 2013 are as follows:

The limitation under Section 402(g)(1) on the exclusion for elective deferrals described in Section 402(g)(3) is increased from $17,000 to $17,500.

The annual compensation limit under Sections 401(a)(17), 404(l), 408(k)(3)(C), and 408(k)(6)(D)(ii) is increased from $250,000 to $255,000.

The dollar limitation under Section 414(v)(2)(B)(ii) for catch-up contributions to an applicable employer plan described in Section 401(k)(11) or Section 408(p) for individuals aged 50 or over remains unchanged at $2,500.

The annual compensation limitation under Section 401(a)(17) for eligible participants in certain governmental plans that, under the plan as in effect on July 1, 1993, allowed cost‑of‑living adjustments to the compensation limitation under the plan under Section 401(a)(17) to be taken into account, is increased from $375,000 to $380,000.
