Timing: Your Initial Enrollment Period
Your Initial Enrollment Period is a seven-month window: three months before you turn 65, the month you turn 65, and three months after. If you explore during this window, your coverage starts on the first of the month you turn 65 with no penalty. If you miss this window and explore later, your Part B premium will increase by 10 percent for each year you delayed — that increase is permanent and stays with you for life.
If you're still working at 65 and have health insurance through your employer, you may be able to delay Part B enrollment without penalty, but you must have coverage from the employer plan. Talk to your employer's benefits office or call Social Security before your Initial Enrollment Period ends to confirm whether you may have access to for this exception.
