How can I avoid IRMAA surcharges?

If you are on Medicare or getting close to Medicare age, there is a cost that can catch you off guard: IRMAA, or the Income-Related Monthly Adjustment Amount.

What makes IRMAA especially easy to miss is the timing. Your surcharge generally is not based on what your income looks like right now. It is based on your income from two years ago.

That means a financial decision you make today could quietly show up in the form of higher Medicare premiums two years later.

Why IRMAA Requires You to Think Two Years Ahead

IRMAA applies to Medicare Part B and Part D premiums when your income reaches certain levels. At the higher tiers, the additional amount can add hundreds of dollars per month, per person.

The problem is that many people do not connect a financial decision today with a Medicare bill two years from now.

A large Roth conversion may increase your income for the year. So can realizing a significant capital gain or selling a rental property. Those decisions may be completely intentional, but if you are approaching Medicare age or already enrolled, they also need to be viewed through the IRMAA lens.

Instead of looking only at this year’s tax impact, ask what the transaction could do to your Medicare premiums two years from now.

That two-year window needs to become part of the planning process.

Roth Conversions Are Powerful, but Timing and Size Matter

Roth conversions can play an important role in long-term tax planning, but that does not mean you should convert as much as possible without considering the consequences.

Because a Roth conversion increases your reported income, a large conversion can potentially push you into a higher IRMAA tier.

This becomes particularly important as you get closer to Medicare age.

The question is not simply whether a Roth conversion makes sense. You also need to consider when to make the conversion and how much to convert.

A conversion that fits well into your overall tax plan may look different once you factor in the Medicare impact two years later. That is why Roth conversions should not be evaluated in isolation.

The long-term tax benefit and the potential effect on Medicare premiums need to be considered together.

The Accounts You Withdraw From Can Change the Picture

Your retirement withdrawal strategy also matters.

Once you begin taking money from different accounts to fund retirement, the source of those withdrawals can affect your reported income. Pulling money from the right accounts in the right order may help you manage your income and potentially stay below an IRMAA threshold.

This is another reason retirement income planning is more complicated than simply deciding how much money you need to spend each year.

You also have to consider where that money comes from.

If you have multiple account types available, the sequence of withdrawals can influence your taxable income. That makes withdrawal planning an important part of managing potential Medicare surcharges.

Again, the goal is to look ahead rather than react after the higher premium appears.

A Life-Changing Event May Give You a Chance to Appeal

Sometimes the income Medicare is using no longer reflects your current situation.

For example, perhaps you earned considerably more two years ago but have since retired. Or your financial circumstances changed because of the death of a spouse or a divorce.

Certain life-changing events may allow you to appeal an IRMAA determination through Form SSA-44.

If you qualify, Social Security may be able to reconsider the income being used to calculate your surcharge. Depending on the circumstances, that can reduce or potentially eliminate the additional amount.

This is an important distinction because sometimes the issue is not how you planned your income. The issue is that Medicare is looking backward at an income level that no longer represents your financial life today.

IRMAA Is Something You Plan Around, Not Just React To

The biggest takeaway is that IRMAA planning starts before you receive a Medicare bill.

A Roth conversion, a large capital gain, the sale of a rental property, or a retirement withdrawal can all have consequences that appear two years later. Looking at each decision through that two-year window gives you a better understanding of how today’s income may affect future Medicare costs.

That does not mean every decision should revolve around staying below an IRMAA threshold. It means Medicare premiums should be part of the conversation when you are deciding how much income to recognize and when.

IRMAA is not something you want to discover after the fact. When you plan income two years at a time, you have a better opportunity to minimize unnecessary surcharges and coordinate Medicare with the rest of your retirement tax strategy.
