The 7 Hidden IRMAA Traps Retirees Over 62 Must Avoid
How to Avoid Unexpected Medicare Premium Increases
Many Americans approaching retirement focus on investments, taxes, and Social Security benefits. But one costly surprise that often catches retirees off guard is IRMAA.
IRMAA stands for Income-Related Monthly Adjustment Amount, a surcharge applied to certain beneficiaries enrolled in Medicare. These surcharges increase premiums for Part B and Part D and are based on income reported to the Social Security Administration.
What makes IRMAA tricky is that Medicare calculates your premiums using income from two years earlier, meaning financial decisions today may affect Medicare costs years later.
For retirees over age 62, understanding these rules early can help prevent unexpected healthcare expenses.

The following thresholds illustrate how income levels can affect Medicare premiums.

IRMAA Tier 1
$129,000 â $161,000
IRMAA Tier 2
$161,000 â $193,000
IRMAA Tier 3
$193,000 â $500,000
IRMAA Tier 4
Over $500,000
Highest IRMAA tier

Part B Premium Level
$206,000 or less
Standard premium

IRMAA Tier 1
$258,000 â $322,000
IRMAA Tier 2
$322,000 â $386,000
IRMAA Tier 3
$386,000 â $750,000
IRMAA Tier 4

Highest IRMAA tier
Because these brackets operate as income cliffs, even a small increase in income can trigger significantly higher premiums.
The 7 Hidden IRMAA Traps
1. The Two-Year Lookback Rule
Medicare premiums are based on income reported two years prior.
Example:
Medicare Year
Tax Return Used
2026 premiums
2024 income
2027 premiums
2025 income
Large financial events today can affect Medicare premiums years later.
2. Crossing an IRMAA Threshold by Accident
IRMAA tiers operate like tax brackets but without gradual increases.
If income exceeds a thresholdâeven slightlyâretirees move to the next tier and pay higher premiums.
Monitoring income levels near year-end is often an important planning step.
3. Large Retirement Account Withdrawals
Withdrawals from tax-deferred accounts such as:
⢠traditional IRAs
⢠401(k) plans
⢠employer retirement accounts
are generally counted as taxable income, which directly affects IRMAA calculations.
A single large withdrawal can unintentionally trigger higher Medicare premiums.
4. Required Minimum Distributions
At age 73, retirees must begin Required Minimum Distributions (RMDs) from most retirement accounts.
For individuals with large balances, these mandatory withdrawals can significantly increase reported income and push retirees into higher IRMAA tiers.
5. Capital Gains Events
Selling appreciated assets can produce large capital gains that increase modified adjusted gross income.
Examples include:
⢠selling investment property
⢠liquidating brokerage investments
⢠selling appreciated stock
Even though capital gains may be taxed differently, they still count toward IRMAA income calculations.
6. Not Appealing IRMAA After Retirement
Many retirees donât realize they can request an IRMAA reconsideration after certain life-changing events.
Examples include:
⢠retirement or reduction in work hours
⢠death of a spouse
⢠divorce
⢠loss of income-producing property
If income drops due to one of these events, retirees may submit Form SSA-44 to the Social Security Administration to request a new determination.
This can sometimes reduce Medicare premiums sooner rather than waiting for the two-year lookback to adjust.
7. Ignoring the Age 62-65 Planning Window
The years before Medicare eligibility may be the most important planning period.
During ages 62â65, retirees can evaluate:
⢠retirement account withdrawal timing
⢠Social Security start dates
⢠future IRMAA exposure
Once enrolled in Medicare, premiums are already tied to prior tax returns, limiting flexibility.
Why Early Planning Matters
Higher income in retirement is generally positiveâbut without planning, it can unintentionally trigger higher Medicare premiums.
Understanding how income interacts with Medicare and Social Security rules can help retirees make more informed financial decisions.
Even modest adjustments to income timing may influence long-term healthcare costs.
