The 55–67 Checklist: 6 Ages Where Retirement Mistakes Get Expensive
Between age 55 and age 67, the federal government hands you a timeline of strict thresholds. Miss 1 by 30 days, and you can trigger permanent lifetime premium surcharges or delayed payouts.
Here is the quick-reference cheat sheet for the critical milestones:
- Age 55 (The Rule of 55): If you leave your job during or after the calendar year you turn 55, you can take penalty-free distributions from your current 401(k). If you roll it into an IRA prematurely, that liquidity locks up again until age 59½.
- Age 59½ (Standard Access): The 10% early withdrawal penalty disappears across all traditional retirement accounts.
- Age 62 (The Earliest Check): Social Security becomes available at a permanent discount of up to 30% off your Primary Insurance Amount. Earnings tests also apply if you continue working while collecting.
- Age 63 (The IRMAA Look-Back): Medicare tracks your Modified Adjusted Gross Income starting January 1 of this year. High capital gains or large Roth conversions completed at 63 will trigger Part B and Part D surcharges when you reach 65.
- Age 65 (The Medicare Line): Your 7-month Initial Enrollment Period begins (3 months before your 65th birthday, your birthday month, and 3 months after).
- Ages 66–67 (Full Retirement Age): Full benefit access with zero earnings caps. Every year you delay filing beyond this point earns an 8% annual delayed retirement credit until age 70.
