HOW DO ROTH CONVERSIONS AFFECT IRMAA?
A Roth conversion increases taxable income in the year the conversion occurs. Because Medicare generally uses a two-year lookback period when calculating premiums, a Roth conversion can increase Medicare Part B and Part D premiums through IRMAA surcharges two years later.
What Is a Roth Conversion?
A Roth conversion occurs when assets are moved from a traditional IRA into a Roth IRA.
Why Roth Conversions Trigger IRMAA
Because Roth conversions increase Modified Adjusted Gross Income (MAGI), they can increase Medicare premiums.
Understanding the Two-Year Lookback
Many retirees are surprised to learn that Medicare does not use current-year income when calculating premiums. Instead, Medicare generally uses income from two years prior to determine whether IRMAA surcharges apply. If you're unfamiliar with IRMAA, learn more about What Is IRMAA and How Does It Affect Medicare Premiums? before evaluating a Roth conversion strategy
Understanding how Medicare calculates premium surcharges is critical before evaluating any Roth conversion strategy.
Why Paying Higher Medicare Premiums May Be Worth It
While nobody enjoys paying higher Medicare premiums, avoiding IRMAA should not be the primary objective. The primary objective should be reducing lifetime taxes.
How Roth Conversions Can Reduce Future IRMAA
Smaller traditional IRA balances generally mean:
• Smaller future RMDs
• Lower future taxable income
• Lower future Medicare premium risk
Many retirees are surprised to learn that a Roth conversion may temporarily increase Medicare premiums while reducing future Medicare costs.
The Ideal Roth Conversion Window
For many retirees, the most attractive Roth conversion period occurs between retirement and age 73.
Case Study
Assume a married couple retires at age 65 with $2.5 million in traditional IRAs. Strategic Roth conversions may reduce future RMDs, improve tax efficiency, and lower future IRMAA exposure.
