Penalties

Late enrollment penalties for Part A, B, and D — how to avoid them.

Signing up late for Part B or Part D can result in a lifetime penalty added to your monthly premium.

Key points

  • Part B penalty: 10% of the standard premium for each full 12 months you delayed, added for life.
  • Part D penalty: about 1% of the national base premium per month you went without creditable drug coverage.
  • Part A penalty applies only if you have to pay a premium for Part A.
  • Qualifying employer coverage or a Special Enrollment Period can protect you from penalties.
