Waiting until full retirement age to sign up for Social Security helps avoid reduced monthly benefits, which is crucial for those relying on this income. However, circumstances like job loss or health issues may force early claims, which can lead to regrets; fortunately, there’s a do-over option that allows individuals to withdraw their application and reapply later, provided they repay all benefits received within a year. To make informed decisions, it’s essential to understand Social Security rules and calculate the long-term financial impact of claiming at different ages.
