Income Related Monthly Adjustment Amounts IRMAA Medicare PremiumsThis post was last updated on January 07, 2024, to reflect all updated information and best serve your needs.

Interested in keeping your medical costs low in retirement? Failing to plan out key details could cost you if you’re not careful. Income Related Monthly Adjustment Amounts (IRMAA) for your Medicare Part B and Part D premiums are a prime example.

Let’s imagine that our good pal, Max Benny, doesn’t get along so well with his Aunt IRMAA. As a matter of fact, he tries to avoid her at all costs. Then one day, she shows up on the front porch, suitcase in hand, “My favorite nephew! Aren’t you glad to see me?” – I’ll take NO for 800, Alex.

Are you over the age of 60? Did you know that healthcare is likely your biggest unknown expense in retirement? Check out our simple 3-step Medicare guide that could save you thousands in surprise medical bills or penalties.

What is Income Related Monthly Adjustment Amounts (IRMAA)

In short, IRMAA will make your Medicare premiums go up. It goes without saying, we want to keep Aunt IRMAA as far away as possible. She can be a real drag [on your wallet]!

Determinations (initial and all subsequent) of IRMAA are based on your modified adjusted gross income (MAGI) from two years prior. In other words, the Social Security Administration (SSA) uses your MAGI for 2022 to determine your Medicare premiums for 2024. If your income for 2022 was above certain thresholds, then your premiums will be higher (Hello, Aunt IRMAA!).

Aunt IRMAA Follows the Money

Don’t get us wrong, Max will be cordial with Aunt IRMAA, but he’s not going to be very happy. There is a solution. If she doesn’t think Max has much money, she’ll probably leave him alone.

The only way that Aunt IRMAA pops into town is if Max’s MAGI gets too high. This is determined when you file your taxes with the IRS. The name of the game is to make sure your MAGI is below the applicable thresholds.

My Life Changed Over the Last Two Years

Your situation may have changed significantly in the last two years (ever been through a pandemic?). If that’s the case, then you can request to have you’re the IRMAA determination reevaluated.

The SSA will send you a notice upon initial determination letting you know your costs as well as the process to appeal. You can appeal for things like a life changing event (LCE) such as a marriage, death of a spouse, divorce, or even significant changes in your work status.

There are other reasons to appeal the decision as well. If the IRS information used was incorrect, then you can appeal based on that. Regardless, if you think there has been a change or mistake in your IRMAA determination, reach out right away.

Planning to Avoid Aunt IRMAA Entirely

You’ll want to plan for Aunt IRMAA and keep her visits to a minimum. Looking long-term and paying close attention to your MAGI over time is best. This is especially important starting the year you’ll turn 63. Some tax-saving strategies like Roth conversions will inflate your income and affect your premiums.

In a perfect world, you’d have income and expenses that are even every year and never go above the threshold amounts. There are a couple ways to think about this. Keeping expenses low reduces the need for more income. On the other hand, more income isn’t the worst thing either – except for the tax part.

Required Minimum Distributions

Required Minimum Distributions (RMDs) can really cause a lot of headaches. Max Benny knows how much Aunt IRMAA likes RMDs too. She loves them and can’t get enough.

RMDs push your income higher and therefore have the potential to raise your Medicare premiums. This can really stink because you see the reduction in your income every month. RMDs take a good thing (more money) and take the fun out by adding extra taxes and costs.

Roth Conversions: Right Time, Right Amount

Roth conversions are a very powerful antidote to RMDs. If you go too far too close to age 65, you might end up with the same issues with Aunt IRMAA. For instance, if you complete a mega backdoor Roth conversion at age 63 or later, you’ll potentially increase your Medicare premiums. Then you’re trading tax savings to pay for Medicare premiums – not what we were hoping for.

However, it could be that the tax savings far outweigh the higher Medicare premiums. Regardless, you need to be aware and avoid this if possible. We want to be intentional about what we’re doing and not get caught off guard.

In reality, you’ll probably want to look at spreading Roth conversions out over time. This is a great strategy to minimize your tax bill over the course of your entire lifetime. You should take a comprehensive, long-term look at all the variables and make a well-balanced plan.

Calculating Modified Adjusted Gross Income (MAGI)

It’s important to note how the SSA determines your modified adjusted gross income (MAGI) in the first place. In short, it’s calculated by taking your adjusted gross income (AGI) and adding any tax-exempt interest like income from municipal bonds. This means that maximizing “above the line” deductions from income is still helpful.

Above the Line Deductions

Above the line deductions reduce your taxable income before taxes are applied. In other words, your AGI is your total (gross) income minus above the line deductions. The IRS allows for many deductions (not to be confused with credits). Self-employment expenses or contributions to a 401(k), IRA, or HSA would be examples of above the line deductions.

How Much is Too Much?

Knowing all the thresholds is helpful. If you know you’re going to make too much to avoid IRMAA altogether, then you can at least attempt to avoid the next higher premium increase. The chart below shows the current (2024) Medicare premium increases.

Significant Annual Increase

If you were paying the minimum Part B and Part D premiums and get hit with the first level of IRMAA, you’ll pay an additional $993.60 in Part B and D premiums for that year. Ouch! If you cross the next threshold, your annual premiums for the year would add a total of $2,492.40 for the year!

It doesn’t take long to see that the pain of Aunt IRMAA increases the higher your income goes. This would be even more painful if you barely crossed one of the income thresholds and could have avoided it.

Crossing Thresholds

If you know that you’ll make more than the first threshold, then you don’t want to increase your income unnecessarily (selling shares in your brokerage account, selling an investment property, etc.). On the other hand, if you already know you’ll be over the first threshold, you can relax until you start getting closer to the next threshold.

More importantly, if your taxable income in retirement is going to be close to one of the thresholds already, avoiding RMDs or other taxable events becomes even more important. That’s why you want to look ahead to create a solid gameplan.

Proper Planning Goes a Long Way

The main takeaway is that if you don’t plan for Aunt IRMAA, then she’ll show up at the worst possible time. Obviously, you can’t control everything. Knowing how to optimize your income and expenses in retirement is super helpful.

You’ll want to be intentional about how you accumulate income, apply prudent tax strategies, and implement well-planned retirement income tactics. Getting all the pieces to work in concert over the course of your lifetime is essential. Any method used in a vacuum will probably be less effective.

Final Thoughts About IRMAA

Getting hit with higher Medicare costs might not be the end of the world if you’ll be saving much more in taxes. However, if you can avoid paying more money for the same coverage, that’s always better. Increases in Medicare costs just seem to hurt more for some reason.
