If you have enough wealth, your Medicare costs – specifically your premiums – might be more than you had bargained for. Not everyone knows this, but there are Medicare surcharges (officially called Income Related Monthly Adjustment Amount, or IRMAA) that correspond to income brackets.
These additional costs can really add up. It is the highest-earning 5% of Medicare recipients who pay more for their health coverage.
What Does Medicare Cost?
There are many different costs associated with Medicare. You may pay monthly premiums, IRMAA (see below), coinsurance, as well as co-pays and deductibles.
Your total out-of-pocket costs for Medicare will vary tremendously depending on the types of coverage you select, your income, where you live, your health status, and healthcare usage.
For a personalized estimate of your Medicare costs, use the Boldin Retirement Planner. It will help you estimate your total lifetime out of pocket medical spending – including calculating your premiums based on your income.
What is IRMAA?
IRMAA stands for Income Related Monthly Adjustment Amount. Medicare.gov explains that, if your modified adjusted gross income (MAGI) as reported on your IRS tax return from two years ago is above a certain amount, you’ll pay the standard premium amount and IRMAA.
IRMAA is an extra cost added to your premiums – specifically parts B and D. Keep reading below to learn about Medicare premiums and just how significantly they rise for those with higher income.
What is the Maximum IRMAA You Might Pay?
The standard monthly Medicare Part B premiums in 2024 are $185. However, if you are in the highest IRMAA income bracket for Parts B and D, you will pay at least an additional $628.90 a month or $7,546.80 a year.
How Can You Reduce a Medicare Surcharge?
With some planning, there are steps you can take to avoid or reduce IRMAA.
Here are 5 ideas:
1. Find Out in Which Future Years You Will Pay a Medicare Surcharge, IRMAA
You can use the Boldin Retirement Planner which provides you with an IRMAA analysis. You can see your projected annual income and assess when you might be assessed for IRMAA and how much for every year from now through your (and your spouse’s) longevity.
NOTE: Your IRMAA payments are determined by your MAGI from two years earlier. So, the IRMAA you would owe in 2028 is dictated by your 2026 earnings.
2. Take Steps to Minimize Taxable Income
If you can lower your taxable income below an IRMAA bracket, you can save hundreds if not a thousand or more on the surcharges. If you are even one penny over the bracket, you will pay IRMAA.
However, minimizing your retirement income can be tricky, especially if you are already taking your Required Minimum Distributions (RMDs) from your tax deferred accounts.
Planning ahead is key. You may be able to shelter income in certain years, manage capital gains, utilize Medicare Savings Accounts, take charitable distributions and consider other strategies. Working with a tax accountant or a Certified Retirement Planner may be helpful.

3. Consider a Roth Conversion
You can convert money from your taxable retirement savings accounts into a Roth account to avoid having to take RMDs. This can be a great way to reduce taxable income and enable you to avoid IRMAA.
Use the Roth Conversion Explorer in the Boldin Retirement Planner to see your potential opportunity for reducing your tax and IRMAA liability.
You can use this tool to explore only converting to IRMAA brackets.
5. Let Medicare Know if Your Circumstances Have Changed
Your IRMAA is based on your income from two years ago. If your circumstances have changed since that time, you can file an appeal with Medicare to let them know about a reduction in income.
Events that might make Medicare reassess your IRMAA include: marriage, divorce, spouse’s death, loss of a job, loss of income generating property, loss of your pension and more.
6. Create and Maintain Your Overall Retirement Plan
Healthcare is a major consideration when planning a secure retirement, but there are hundreds if not thousands of different elements that impact your current and future wealth and security.
Make sure that you have a comprehensive plan and that you keep it updated.
