Federal employees who retire on June 30, 2025, benefit from a mid-year financial transition. This date aligns with the end of the second quarter, making it easier for those tracking their TSP (Thrift Savings Plan) withdrawals, COLA (Cost-of-Living Adjustment) calculations, and FERS Special Retirement Supplement (SRS) eligibility. Additionally, a June 30 retirement ensures annuity payments begin in July 2025, reducing financial uncertainty. Choosing this date also allows for a well-timed break before the second half of the year begins, ensuring a smooth shift into post-retirement life. If you’re seeking the best dates to retire from the federal government in 2025, June offers financial and administrative advantages.
