Working After 65
Delaying Medicare while covered by employer insurance.
If you're still working at 65 with employer health coverage, you may be able to delay Part B without penalty — but only if the coverage qualifies.
Key points
- Employer size matters: 20 or more employees generally lets you delay Part B safely; under 20, Medicare usually becomes primary.
- When you eventually leave the job, you get an 8-month Special Enrollment Period.
- Most people still enroll in premium-free Part A at 65.
- HSA contributions must stop once you enroll in any part of Medicare.
