What is the Medicare IRMAA 2024 Schedule?

 Many years ago, I was still new to the Medicare insurance business. I had a few hundred clients but no high-income earners. I knew what Medicare IRMAA was, but I had never met someone subject to the IRMAA tax before Doug. He was an improbable candidate. After many years and thousands of clients later, I am very familiar with IRMAA, and I can tell you what the Medicare IRMAA 2024 schedule is all about.

Don’t Judge A Book by Its Cover

Doug drove up to my office on a loud Harley Davidson hog, his long hair waving in the wind. He was a big dude, and his leathers made him even bigger. I was a little nervous, but we sat down and took care ofIncome determines your Medicare Part B premium Medicare business.

A few months later, when Doug’s Medicare started, I got a distressed phone call. “You said my Medicare premium was going to be this amount. It’s three times that!”

I was befuddled. I got my calculator out but couldn’t figure out why it was so high. Finally, I said, “Your income would have to be unusually high to be charged that much.”

Doug got quiet.  “How high?” he asked. The first IRMAA bracket was $85,000 for a single person at the time. Doug guffawed and said, “Hell, my income is way more than that.”

Turns out Doug was not only a retired municipal employee with a pension and Social Security. He was also retired from the military with 20 years of service and a pension. On top of that, he had built up a stock portfolio that kicked out around $30,000 in dividend income a year.

I should have taken the adage, ‘Don’t judge a book by its cover’ more seriously.

Since then, I have always brought up income in my introductory meetings and how income affects Medicare Part B premiums. Zip code or fashion choices are no guarantee of what someone’s income may be.  

What Is Medicare IRMAA?

what is medicare part b irmaaIRMAA stands for income-related monthly adjustment amount. The government loves acronyms. Medicare IRMAA is a surcharge that high-earners pay for their Medicare Part B monthly premium.

Everyone pays a tax for Medicare during their working years. The Medicare tax is included in the FICA (Federal Insurance Contribution Act) you pay and is recorded on your pay stubs. Your Medicare tax is currently 1.45%. It is graduated up for higher earners.

In 1966 when the Medicare program began, the cost to workers was $3 per person per month, which is approximately $30 in today’s dollars. The baby boomers are leaving the workforce in huge numbers currently, so fewer workers are paying the Medicare tax. Medicare tax revenue is dropping like a stone in relation to the number of people collecting.

As Baby Boomers leave the workforce, they enter Medicare. The number of workers paying into Medicare is contracting, and the number taking out of the program is ballooning. Medical expenses are climbing. The current demographics are crushing Medicare’s ability to provide the same level of service as in the past because expenses are outpacing tax revenue.

Medicare Prescription Drug Improvement & Modernization Act

In 2003 Congress passed the Medicare Prescription Drug Improvement and Modernization Act of 2003 (MMA). In the legislation, Congress addressed the coming shortfall in Medicare revenue.congress is the institution that legislated the IRMAA rules in the existence. Congress’s answer was to raise taxes. The top 7 percent of earners were required to pay more into the program. There are currently 65 million Medicare beneficiaries. The IRMAA tax will affect approximately 4.6 million people out of the 65 million. If you are a politician, it is better to keep 60.4 million voters happy, even at the expense of making 4.6 million unhappy.  

A little-known fact is Medicare beneficiaries pay less than 25 percent of the actual Medicare cost. The current Part B premium is only $174.70. That premium covers about a fifth of the actual cost. In the MMA, Congress increased the Part B premium based upon your income. The IRMAA increases the percentage that upper-income Medicare beneficiaries actually pay for their Medicare. Instead of paying only 25 percent of the Medicare cost, IRMAA payors pay for 35, 50, 65, 80, or 85 percent of the actual Medicare cost. The additional revenue the IRMAA tax brings in is allocated to offset Medicare’s budget shortfall.

medicare irmaa is based upon your tax returns. How Does the Medicare IRMAA 2024 Schedule Work?

Medicare IRMAA is a different calculation from the progress income tax rates the IRS uses for federal income tax brackets.

You do not pay a federal income tax rate on everything you make. The federal government divides your taxable income into chunks — also known as tax brackets — and each chunk gets taxed at a progressively higher rate. The beauty of this is that no matter which bracket you’re in, you won’t pay the highest tax rate on your entire income! Only the “chunk” in that bracket. For example, you pay 10% on the first $40,000 of income, 25% on the next $20,000 of income (total of $60,000), and 35% on the next $15,000 of income (total of $75,000).  

Memedicare irmaa chartdicare IRMAA 2024 schedule utilizes a “cliff” style of assessment instead. That means if you are just $1 over the cut-off for the next tier of IRMAA, you will pay the higher amount. There are no brackets for each chuck of income like federal income tax and no graduation or progression in the amount you pay. The Medicare 2024 Part B IRMAA premium brackets change when you earn one dollar more above the line.

What Is Medicare IRMAA Based Upon in 2024?

The IRS and Social Security work with Medicare. Medicare determines your income based on your most recent tax filing. So, for example, you are going on Medicare in 2023. The most recent tax filing was in 2022 for 2021. Usually, IRMAA is based on a two-year lag in your income.

How Is Medicare IRMAA Calculated?

Your adjusted gross income (AGI) determines where you fall in the Medicare IRMAA 2024 schedule. The AGI, however, differs from the MAGI (Modified Adjusted Gross Income) you usually think of when doing your taxes. AGI for IRMAA is a Medicare-specific form of MAGI. It is your AGI with tax-exempt bonds–-both earned and accrued interest–-added back into your income. Interest from U.S. Savings bonds used for higher education is added back. Earned income from working abroad that was not added to gross income is included.  MAGI (Modified Adjusted Gross Income) for Medicare differs from what MAGI usually means for non-healthcare-related purposes.

You will be sent your Medicare IRMAA Initial Determination Notice soon after you enroll in Medicare Part B. Confirm the income amounts the IRS uses are correct–they make mistakes, too.

what does irmaa stand for in medicareMedicare Financial Planning

Examine the Medicare IRMAA 2024 schedule to see if you are close to any of the limits.  

What are your plans for the future? Will you withdraw from retirement savings this year or in future years? A home sale can spike your income when your intention is only to downsize and move to a one-story home. Capital gains from a stock and property sale or other appreciated assets may come back to visit you as an unexpected IRMAA tax.

Any of these actions may increase your income substantially enough to move you into and/or up the IRMAA brackets, requiring you to pay more. Knowing and planning for these events, you can move assets in smaller amounts over time to avoid large spikes in income and, consequently, increases in your income tax and IRMAA Part B premium.

How Do I Reduce Medicare IRMAA?Medicare Irmaa

Charitable donations of cash, appreciated assets, and appreciated stock can reduce your taxable and IRMAA surcharge, as well as contributions to 401ks, IRAs, and other qualified programs. Some minor adjustments may drop you down a bracket and save you some money.

What Our Clients Are Saying About Omaha Insurance Solutions

What an adventure! We started getting ourselves educated about Medicare insurance coverage several years ago – a bit too early, given how things change every year! While we had a foundational knowledge of the basics, it was helpful to work with Chris to fine tune all the nuances and make sure we were enrolling in the plan that best met our needs. Fingers crossed that our retirement and future insurance needs do not present any unwelcomed “surprises”. If that’s the case, we’ll be setting up time with Chris to help us through it!

After I acknowledged that I was nearing Medicare age, I realized I knew nothing about it so I reached out to two very informed friends. They both recommended Chris Grimmond. They praised his knowledge and helpfulness so I gave him a call. After meeting with Chris, I was 100% convinced that we would be working together. He answered all my questions and helped me understand the Medicare system. I feel confident I made the right decision to work with Chris and his team at Omaha Insurance Solutions.
