How Your Income at 63 and 64 Shapes Medicare Costs at 65
The two years before Medicare eligibility can permanently affect your premiums. Here's why strategic tax planning in your early 60s matters.
Most Americans think of retirement tax planning as a single event — something that happens when they stop working or begin drawing Social Security. But there is a quieter, often overlooked window that carries outsized financial consequences: the two calendar years immediately before you turn 65 and enroll in Medicare.
Medicare premiums are not flat fees. For higher-income beneficiaries, the program imposes an Income-Related Monthly Adjustment Amount, or IRMAA, which can substantially increase what you pay for Part B and Part D coverage. Critically, the income figure Medicare uses to calculate that surcharge is based on your tax return from two years prior — meaning the income you report at 63 and 64 directly determines what you will owe at 65.

This creates what financial planners sometimes describe as a second tax window. The first is the well-known opportunity to convert traditional IRA funds to a Roth account during low-income years. The second is the more urgent task of actively managing your modified adjusted gross income in the years just before Medicare kicks in. A large Roth conversion, the sale of appreciated assets, or even a one-time consulting payment during those years could push you into a higher IRMAA bracket — adding hundreds or even thousands of dollars annually to your Medicare costs.
The stakes are asymmetric. Once your income is reported and Medicare sets your premium tier, appealing the decision requires demonstrating a qualifying life event such as retirement or divorce. Simply having a high-income year — even for legitimate, non-recurring reasons — typically does not qualify for an exception. That rigidity makes proactive planning in your early 60s far more valuable than any corrective action taken after the fact.
For advisors and individuals alike, the takeaway is structural: Medicare premium planning deserves its own dedicated review at age 62 or 63, separate from broader retirement income strategy. Coordinating Roth conversions, capital gains realizations, and required minimum distributions around IRMAA thresholds is no longer optional for anyone navigating retirement with meaningful assets.
