Retirees frequently make two expensive mistakes that can significantly reduce their total retirement income [1].

These errors often occur during the early years of retirement. Because these decisions impact the lifelong trajectory of a portfolio, failing to optimize timing can lead to premature depletion of savings and higher tax burdens.

One primary mistake involves the timing of Social Security claims [3]. Claiming benefits early reduces the monthly payment amount for the remainder of the retiree's life. By delaying these claims, individuals can increase their guaranteed monthly income, providing a larger hedge against inflation and longevity risk.

Another critical error is the mismanagement of account withdrawals [3]. Mistimed or premature withdrawals from retirement accounts can increase the amount of taxes owed to the government. This often creates a cycle where retirees must withdraw even more from their principal to cover the tax liability, effectively accelerating the exhaustion of their assets.

Financial guidance suggests that the first few years of retirement are the most volatile for decision-making [3]. During this window, the transition from accumulating assets to spending them requires a strategic approach to avoid the two identified errors [1].

While some reports suggest a broader range of errors, including five crucial mistakes in the first five years or nine common tax errors, the core issues of Social Security timing and withdrawal strategies remain central to long-term financial stability [1].

The focus on these two specific errors highlights a shift in retirement planning from simple accumulation to strategic decumulation. As retirees navigate the 'sequence of returns' risk, the timing of Social Security and tax-efficient withdrawals becomes more critical than the total size of the initial nest egg.
