For federal employees under FERS, selecting the best dates to retire in 2025 is crucial for maximizing financial benefits. Retirement dates such as January 11, May 31, October 31, and December 31 are strategically advantageous as they ensure full pay for those months while reducing the potential for income gaps. Additionally, these dates allow federal employees to manage their accrued annual leave effectively before the November 29 deadline. Coordinating retirement dates with Social Security and TSP distributions enhances overall retirement planning.
