Will I get penalized for signing up for Medicare late?
Possibly, and it depends entirely on why you were late. If you had qualifying coverage the whole time, usually a group health plan through an employer with 20 or more employees, you generally will not owe a penalty.
If you simply did not enroll and had no creditable coverage, then yes. Part B adds 10 percent for every full twelve months you delayed and you pay it as long as you have Part B.
Part D adds 1 percent of the national base premium for every full month you went uncovered after 63 days without drug coverage.
How much is the Medicare Part B late enrollment penalty?
Ten percent of the standard Part B premium for each full twelve-month period you could have enrolled and did not. 50. It stays on your premium for life. Note that it counts full twelve-month periods, so a delay of 23 months is penalized at 10 percent, not 20.
How much is the Part D late enrollment penalty?
99 in 2026, for each full month you went without creditable drug coverage. 50 a month added to your plan premium and rounded to the nearest ten cents. It follows you even if you change plans, and the base premium it is calculated against changes each year.
How do I avoid a Medicare late enrollment penalty?
Enroll during your Initial Enrollment Period, or make sure you have creditable coverage every month you delay, and never let a gap run past 63 days. If you are working past 65 with employer coverage, confirm in writing that the drug coverage is creditable and keep that notice.
The single most common way people get penalized is using their full eight-month Part B window after employer coverage ends while missing the two-month window for a drug plan.
Does the Part A penalty last forever too?
No, and Part A is the exception in two ways. It is a flat 10 percent rather than 10 percent per year, and you pay it for twice the number of years you could have had Part A but did not enroll, then it stops.
It also only applies to people who do not qualify for premium-free Part A, which is a small minority, since most people earn premium-free Part A through about ten years of paying Medicare taxes.
Can a Medicare penalty be removed?
Sometimes. A Part D penalty can be reconsidered by Medicare's independent review contractor if you request it within 60 days of the letter, and proof of prior creditable coverage is the evidence that usually wins.
Qualifying for Extra Help stops the Part D penalty from being charged while you have it. Enrolling in a Medicare Savings Program eliminates the Part B penalty. Those last two are real and routinely missed.
Why is my Medicare premium higher than my friend's?
Usually one of two reasons, and they are completely different. Either a late enrollment penalty, which reflects when you signed up, or IRMAA, an income-related surcharge based on your tax return from two years ago.
IRMAA is not a penalty and enrolling on time would not have prevented it. If your income dropped because you retired, you can request a new determination, and a lot of people who qualify for that never file the form.
I got a letter saying I owe a penalty. What do I do?
Do not ignore it and do not just start paying it. Bring it to us, or call the number on the letter.
If it is a Part D penalty you have 60 days from the date on that letter to request a reconsideration, and the most useful thing you can dig up is any notice from a former employer or plan showing you had creditable drug coverage during the months in question.
