It's easy to make mistakes when it comes to claiming Social Security. What are some of the more common mistakes to consider and avoid? Here's what Larry Kotlikoff, a professor at Boston University and president of Economic Security Planning, had to say:

1. Taking benefits too early so as to not lose them. "There is an enormous return for most people to wait until 70 to collect their highest possible retirement benefits," says Kotlikoff. Read Benefits Planner: Retirement ' Delayed Retirement Credits.

2. Thinking you'll regret not taking Social Security when you're dead. "When you're dead, you'll be in heaven, where there are no regrets," he says. "The big risk is not having died without taking benefits. The big risk is taking benefits too early and ending up living to a ripe old age on cat food."

3. Thinking you'll die on time. "None of us will die at our life expectancy, which, after all, is just an average," says Kotlikoff. "We all need to plan for the worst-case scenario, which is living to our maximum, not our expected age of life." Read Life Expectancy Assumptions In Retirement Planning.
