Medicare Part B IRMAA: What High Earners Need to Know

If you have worked hard, saved diligently, and built a solid income for your retirement, Medicare has a surprise waiting for you. It is called the Income-Related Monthly Adjustment Amount, or IRMAA. This is an extra charge added to your Medicare Part B premium if your modified adjusted gross income (MAGI) from two years ago exceeds a certain threshold set by the government.

For most people, the standard Part B premium covers their outpatient care, doctor visits, and preventive services. But if your income pushes past the limit, you will pay the standard premium plus the IRMAA surcharge. This surcharge is recalculated every year based on your tax returns from two years prior. So, the IRMAA you pay this year is based on what you earned two years ago.

The IRMAA brackets are adjusted annually for inflation. If you file your taxes as an individual and your MAGI is above the base threshold, or if you file jointly and your combined MAGI is above the joint threshold, you will fall into one of the IRMAA tiers. The higher your income, the higher the surcharge.

It is important to note that IRMAA applies to both Medicare Part B and Medicare Part D (prescription drug coverage). If you are subject to IRMAA for Part B, you will also pay an extra amount for your Part D coverage, regardless of whether you get it through a standalone plan or a Medicare Advantage plan.

Now, let's talk about how this fits into your overall Medicare strategy. The Medicare module is simple: you have two paths, not two products. You can choose Traditional Medicare (Parts A and B) and add a Medigap policy to fill the holes, or you can choose Medicare Advantage (Part C), which replaces Traditional Medicare with a private network plan.

If you choose the Traditional path, your Medigap premium is completely separate from your Part B premium and the IRMAA surcharge. Medigap premiums are based on your age, location, and the plan you choose, not your income. However, you still have to pay your Part B premium, including any IRMAA, directly to Medicare.

If you choose Medicare Advantage, you still have to pay your Part B premium and any IRMAA surcharge, even if the Advantage plan itself has a $0 premium. The IRMAA is a federal requirement, and no private insurance plan can waive it for you.

If your income has dropped significantly due to a life-changing event - like retirement, divorce, or the death of a spouse - you do not have to just accept the IRMAA surcharge. You can file an appeal with the Social Security Administration using Form SSA-44. If approved, they will recalculate your premium based on your current, lower income.

Navigating Medicare costs can feel like walking through a minefield, especially when you are penalized for your financial success. But you do not have to figure it out alone. We are on your side of the table, ready to walk you through every option and make sure you are not paying a dime more than you have to.
