How the Part B late enrollment penalty works
The Part B late enrollment penalty can last as long as you have Part B. In general, the penalty is 10% of the standard Part B premium for each full 12-month period that you could have had Part B but did not enroll and did not have qualifying employer coverage. COBRA and retiree coverage usually do not protect you from the penalty.
