Don’t Get Blindsided by the Medicare “Luxury Toll”
Remember the last time you thought you had a clear path, like planning a perfect road trip through the autumn foliage of New England? You plotted your stops, budgeted for gas and maybe a few clam shacks, feeling good about the journey ahead. Then, BAM, you hit an unexpected toll plaza with a hefty surcharge, not for the road itself, but because your car was just a little too nice, or you had too much luggage. Suddenly, your carefully planned budget takes a hit, and that scenic drive feels a little less relaxing.
When it comes to Medicare in retirement, many folks face a similar unexpected surprise: the IRMAA, or Income-Related Monthly Adjustment Amount. Think of IRMAA as that “luxury toll” on your Medicare Part B and Part D premiums. If your income goes above certain thresholds, the government asks you to pay a greater share of your Medicare costs, adding a surcharge to your standard premiums. It’s not about how much you use Medicare, but how much income you reported a couple of years ago.
Who Gets Hit with the IRMAA Toll?
The Social Security Administration (SSA) determines who pays IRMAA. If your Modified Adjusted Gross Income (MAGI) from two years prior exceeds specific income brackets, you’ll likely receive an Initial Determination Notice. For instance, your 2026 Medicare Part B and D IRMAA will be based on your 2024 tax return. This two-year look-back is a key detail, often catching retirees off guard if a spike in income (like selling a property or taking a large IRA distribution) occurred a couple of years prior. If you have both Medicare Part B and Part D prescription drug coverage, you’ll pay higher premiums for each.
Calculating Your MAGI, the “Luggage” That Matters
So, how do they figure out if you’re carrying “too much luggage” (income) for the standard toll rate? The SSA uses your Modified Adjusted Gross Income (MAGI). This isn’t just your standard adjusted gross income (AGI), but it also adds back certain tax-exempt interest. It’s a broader measure, designed to capture more of your financial picture.
Here’s a quick look at some common income sources that count toward your MAGI for IRMAA purposes:
- Taxable Social Security benefits and pension income.
- Wages, tips, interest, and dividends.
- Rental income and capital gains.
- Distributions from traditional 401(k)s, 403(b)s, and IRAs.
- Tax-exempt interest (like from municipal bonds).
What generally doesn’t count? Distributions from Roth accounts, Health Savings Accounts (HSAs), and life insurance proceeds are typically exempt from this calculation. This difference between traditional and Roth distributions is a big deal when it comes to retirement planning.
Planning Your Route to Avoid the Surcharge
The good news is that IRMAA isn’t a life sentence. Your surcharge can change year to year based on your income. If your income drops, your IRMAA could decrease or even disappear. However, IRMAA surcharges aren’t minimal, potentially costing thousands annually. It’s worth planning to avoid them.
One of the smartest moves you can make is to strategically manage your income in retirement. This is where foresight truly pays off. For married couples, planning is especially critical, as the death of one spouse can lead to the survivor filing individually and potentially jumping several IRMAA tiers.
Consider Roth IRA conversions, which, when planned carefully, can reduce your future taxable income. By converting traditional IRA funds to a Roth account before you’re on Medicare (ideally at least three years prior), you pay the tax now, and then those future tax-free Roth distributions won’t count toward your MAGI for IRMAA. This way, you enjoy tax-free income without triggering those extra Medicare surcharges, making for a much smoother, less costly ride through retirement.
If you believe an IRMAA determination is incorrect, or if you’ve had a life-changing event like retirement, divorce, or the death of a spouse, you can appeal the decision with the SSA. It’s always worth checking if your situation warrants a review.
