While the notion of Social Security benefits seems straightforward at first glance, the program is governed by thousands of regulations, resulting in hundreds — some say thousands — of possible claiming strategies for individuals and couples.
For those who are married, these can be narrowed down to 10 to 15 major strategies, according to Marc Kiner, a CPA and owner of Premier Social Security Consulting and co-founder of the National Social Security Association, which offers the NSSA certificate program in Social Security maximization. Kiner pointed out a handful of these approaches:
Additionally, according to certified financial planner Robert Leitner, president of Financial Advisory Network, those who divorce and then remarry cannot collect on their ex's accounts; unless they remarry after age 60, in which case they can collect survivor benefits.
Social Security's guaranteed compounding behavior from the earliest claiming age (62) to the latest (70) results in a benefit guaranteed to be 76 percent higher, said Ash Ahluwalia, CFP, founder of National Social Security Partners, and this notion can impact other portfolio decisions. For example, conventional thinking around individual retirement accounts is to wait until age 70½ to begin withdrawing funds, while taking Social Security at age 66.
"However, it may be better to do the opposite — take your IRA distribution early and delay Social Security — because the IRA may not grow, but Social Security is guaranteed to grow by 8 percent per year up to age 70," he said.
A fundamental error, said Ahluwalia, is looking at your Social Security benefits without coordinating them with your other assets. "When and how you elect can have a major impact on your income in retirement," he said.
The fact that the claiming rules are in transition sometimes complicates decisions, Ahluwalia noted. He has found that often Social Security staffers themselves get confused, and he has had to send them the regulation code section to support an option.
People need to be aware that, when they file for Social Security, they are making a pension election and they are locked in, he added.
It is possible to change an election decision after the fact, but it comes with serious restrictions. You get one chance to make a change, but with two stipulations: The change must take place within 12 months of filing, and everything you or your beneficiaries received must be paid back, Ahluwalia said.
Social Security is "actuarially neutral" on when to file, said Leitner of Financial Advisory Network. For example, if you file at 62 and live until 82, you'll get a smaller check for a longer period. If you file at 70 and live to 82, you'll be getting a larger check for a shorter time. Overall, you'll be getting the same amount of money.
He also advises clients to be mindful that Social Security could be taxable depending on certain combinations of modified adjusted gross income, Social Security and tax-exempt interest received.
There is a behavioral aspect to Social Security claiming, according to Tim Maurer, CFP, director of personal finance with The BAM Alliance.
"Many people's perspective is that they've paid in to the program, so they want to get as much as possible out of it ASAP," he said. "What's most often written about is getting the most, but it's important to think strategically, not just [gross] numerically."
Maurer wants individuals to consider the point at which they're most likely to run out of money. The answer, he said, is at the end of life, and as a result, he advises them to delay claiming until they need it more urgently.
"We have a tendency to spend what comes in, so behaviorally, if we claim sooner, we'll spend more," he said. "Leaving it in the system forces you to save."
This strategic thinking can mitigate longevity risk, Maurer said.
"If you compound the benefits of working plus delaying Social Security, you will get the most," he added. "The question is: Can you get a better rate of return than 8 percent per year?"
In other words, do you want to spend, or do you want to save?
