When to claim Social Security is one of the most important decisions Americans face when approaching retirement. Recently, several unconventional claiming strategies have come to light – “Free Loan,” “Claim and Suspend,” and “Claim Now, Claim More Later” – that have the potential to pay higher lifetime benefits to some individuals, increasing system costs. In the “Free Loan” strategy, an individual can claim benefits at a given age and later repay them and file again, obtaining an increased benefit from the delayed filing. This strategy is equivalent to a “no interest” loan from Social Security and could potentially cost the program as much as $11 billion a year. “Claim and Suspend” allows an individual to claim benefits and then immediately suspend them, either to put his own benefits on hold if he reenters the workforce or to allow his spouse to claim a spousal benefit while he continues to work and earn delayed retirement credits. The potential cost of allowing couples the option of “Claim and Suspend” is about $0.5 billion dollars a year. In the “Claim Now, Claim More Later” strategy, a married individual claims a spousal benefit while delaying claiming his own retired worker benefit in order to build up delayed retirement credits. This option could potentially cost Social Security $10 billion a year. Of the three strategies, “Claim and Suspend” appears to have the clearest policy rationale as it provides an incentive for individuals to work longer.
