Medicare Penalties Explained 2026
Medicare late enrollment penalties are permanent — they follow you for life. Learn exactly how they work, who is exempt, and how to avoid them entirely.
Important: Medicare late enrollment penalties are permanent and added to your premium for life. There is no way to remove them once assessed — prevention is the only solution.
Medicare Part B Late Enrollment Penalty
The Part B penalty is 10% of the standard Part B premium for each full 12-month period you were eligible but didn't enroll. In 2026, the standard Part B premium is $202.90/month.
Part B Penalty Formula
Example: Delayed 3 years = 30% × $202.90 = $60.87/month added permanently
Part B Penalty by Years Delayed (2026)
| Years Delayed | Monthly Penalty | New Monthly Premium | 10-Year Extra Cost |
|---|---|---|---|
| 1 year | $20.29 | $223.19 | $2435 |
| 2 years | $40.58 | $243.48 | $4870 |
| 3 years | $60.87 | $263.77 | $7304 |
| 5 years | $101.45 | $304.35 | $12174 |
| 10 years | $202.90 | $405.80 | $24348 |
Medicare Part D Late Enrollment Penalty
The Part D penalty is 1% of the national base beneficiary premium ($36.78 in 2026) for each month you went without creditable drug coverage.
Part D Penalty Formula
Example: 24 months without coverage = 24% × $36.78 = $8.83/month added permanently
Who Is Exempt from Medicare Penalties?
You can delay Medicare enrollment without penalty if you have qualifying coverage. Here are the most common exemptions:
Active employer coverage (20+ employee company)
If your employer has 20+ employees, your group plan is primary. You can delay Medicare Parts A and B without penalty. You have 8 months after losing coverage to enroll.
VA health coverage
Veterans with VA health coverage can delay Part D enrollment without penalty. VA drug coverage is considered creditable. However, VA coverage does not exempt you from the Part B penalty.
TRICARE for Life
Military retirees with TRICARE for Life must enroll in Part B to keep TRICARE benefits. TRICARE for Life is considered creditable drug coverage, so no Part D penalty applies.
FEHB (Federal Employee Health Benefits)
Federal employees and retirees with FEHB coverage can delay Medicare enrollment. FEHB is creditable for both Part B and Part D purposes.
Medicaid / Dual Eligible
If you qualify for Medicaid, you may be automatically enrolled in Medicare and won't face penalties. Dual-eligible beneficiaries often qualify for Extra Help with Part D costs.
ESRD (End-Stage Renal Disease)
People with ESRD who qualify for Medicare before age 65 have different enrollment rules. Consult with a Medicare specialist to understand your specific situation.
How to Avoid Medicare Penalties
Know your Initial Enrollment Period
Your IEP is the 7-month window starting 3 months before your 65th birthday month. Mark your calendar and enroll during the first 3 months to ensure coverage starts on your birthday.
Document your creditable coverage
If you have employer, retiree, VA, TRICARE, or FEHB coverage, keep documentation. Your plan administrator must provide annual creditable coverage notices. Save these letters.
Enroll within 8 months of losing employer coverage
When you lose qualifying employer coverage, you have an 8-month Special Enrollment Period to enroll in Medicare without penalty. Don't wait — COBRA does not extend this window.
Don't rely on COBRA to avoid penalties
COBRA is generally not considered creditable coverage for Part B penalty purposes. If you're relying on COBRA after leaving employment, enroll in Medicare promptly.
Work with a licensed Medicare broker
An independent broker can review your specific situation, confirm whether your current coverage is creditable, and help you enroll at the right time to avoid penalties.
