How do I avoid Medicare late enrollment penalty?


Editorial team Published on

You can delay Medicare without penalty by maintaining active group health coverage through your own or a spouse's current job at an employer with 20 or more employees. Learn more on the Official Medicare Working Past 65 Guide.

Key Rules to Delay Penalty-Free

  • Employer Size: Your active employer or spouse's employer must have 20 or more employees (100+ if disabled). COBRA and retiree health plans do not count as active employment.
  • Creditable Prescription Drug Coverage: Your employer plan must provide drug coverage that is expected to pay at least as much as standard Medicare Part D.
  • Health Savings Account (HSA): Stop making contributions to your HSA at least 6 months before you plan to enroll in Medicare to avoid retroactive tax penalties.

When You Leave Your Job

  • Special Enrollment Period (SEP): You get an 8-month window starting the month after your employment or group health coverage ends (whichever comes first) to sign up for Part B without a penalty.
  • Part D Window: You have 63 days after losing creditable drug coverage to enroll in a Part D prescription plan penalty-free.
  • Required Forms: Keep CMS Form L564 signed by your employer as proof of continuous creditable coverage when you finally apply.
