When to begin receiving social security benefits.

• Author: Sarenski, Theodore J.

Social Security Administration (SSA) statistics indicate that a majority of U.S. citizens elect to begin receiving Social Security benefits at age 62; see Song and Manchester, "New Evidence on Earnings and Benefit Claims Following Changes in the Retirement Earnings Test in 2000" (July 2006), available at www.ssa.gov/policy/docs/workingpapers/ wp107.pdf. Is this a wise choice? Is there an optimum age to begin receiving benefits? This column explores the answers to these questions.

An individual who reaches age 62 in 2007 has a full retirement age (FRA) of 66 (i.e., the age at which he or she would receive 100% of his or her Social Security benefits). Opting to receive benefits between ages 62 and 66 results in a reduced benefit. The reduction factor applied to the full benefit is 5/9 of 1% for each of the first 36 months that benefits begin before the FRA, plus 5/2 of 1% for each month in excess of 36 months; see "Find Your Retirement Age," available at www.ssa. gov/retirechartred.htm, and SSA Pub. No. 05-10070," Your Retirement Benefit: How It Is Figured" (January 2007), available at www.ssa.gov/pubs/10070. html. Individuals who turn 62 in 2007 and want to begin receiving benefits immediately will get only 75% of the benefits they would have received had they waited until age 66. There will be no change (other than cost-of-living increases) to these individuals' benefits under their own work histories for the remainder of their byes.

Comparing Break-Even Points

The argument is sometimes made that if individuals saved all of their reduced monthly benefits from age 62 to 66, they would be far ahead of the person who waits until age 66 to begin receiving benefits.

The tax adviser might consider an example with three assumptions: (1) a 5% after-tax return rate; (2) all funds received at either age 62 or 66 are invested; and (3) no withdrawals are made from those investments over life expectancy. The break-even point is somewhere between ages 77 and 78 (see Exhibits 1 and 2 on p. 409).

According to the uniform life expectancy table, life expectancy at attained age 62 is 85.5 years and at attained age 66 is 86.2 years; see Regs. Sec. 1.401 (a)(9)-9, Q&A-1. Based on these life expectancies and a break-even point around age 77, it is always better to begin to receive Social Security benefits at the FRA. But life does not always follow actuarial tables; there are other factors to consider when advising clients when to begin receiving benefits.
