How Medicare IRMAA Surcharges Hit Retirees in 2026

In 2026 a retired couple with a modified adjusted gross income of $206,000 will pay an extra $3,624 per year in Medicare surcharges. These IRMAA fees, which stand for Income-Related Monthly Adjustment Amount, began in 2007 for Part B premiums and expanded to Part D in 2011.

The charges are calculated from your tax return two years prior, so 2024 income determines 2026 costs. For many Americans entering retirement after 50, these unexpected bills can reach nearly $5,000 annually for individuals earning above $103,000 or couples above $206,000.

The fees rise in four additional tiers, with the highest adding more than $5,000 a year per person. Congress designed the system to make higher earners help fund Medicare, yet the brackets have not been adjusted for inflation since 2019.

That means more retirees are getting caught each year as Social Security cost-of-living increases and required minimum distributions push them over the lines.

Current 2026 Brackets and Monthly Costs

For 2026, Medicare sets five income tiers based on 2024 tax returns. Individuals pay the standard Part B premium of $185 per month if their modified adjusted gross income is $106,000 or less.

The first surcharge level starts at $106,001 to $133,000 and adds $74.00 monthly, for a total Part B premium of $259. The next tier runs from $133,001 to $167,000 and adds $185 monthly.

Higher brackets reach $197.90, $274.20 and $359.50 added per month. Part D adds another layer: the base premium averages about $40 but IRMAA can tack on $13.70 up to $81.00 extra per month.

A couple filing jointly faces the same surcharges once their combined income exceeds $212,000. In 2025 the lowest surcharge threshold sits at $103,000 for singles; it rises to $106,000 in 2026 because of a one-time adjustment.

Data from the Centers for Medicare and Medicaid Services show roughly 8 percent of Medicare beneficiaries paid IRMAA in 2024, a share that has grown from 5 percent in 2015.

Why Two-Year Lag Creates Surprises

The Social Security Administration uses your adjusted gross income from two years earlier because that is the most recent tax return available when premiums are set each fall. A person who retires at 63 in 2025 may still show wages from 2023 on their 2024 return, triggering higher 2026 premiums.

Once the higher premium starts, it usually stays in place for one full year even if income drops sharply. Appeals are possible using Form SSA-44 if retirement, divorce, death of a spouse or certain other life-changing events occurred.

In 2023 the SSA approved about 60 percent of the roughly 150,000 appeals filed. Without an appeal, a couple moving from a salary of $240,000 to a pension of $90,000 could pay the top IRMAA tier for an entire year before the system catches up.

Impact on Required Minimum Distributions

Retirees turning 73 must begin taking required minimum distributions from traditional IRAs and 401(k)s. These distributions count as ordinary income and can easily push a household over the $212,000 combined threshold.

The IRS raised the RMD age to 73 in 2023 under the Secure 2.0 Act. For a retiree with a $1.2 million IRA balance at age 73, the first RMD is about $47,000. Added to Social Security of $40,000 and a pension of $35,000, total income can exceed $220,000 and trigger roughly $4,000 in extra Medicare charges for the couple.

Financial planners at Fidelity and Vanguard report that clients who convert portions of traditional IRAs to Roth accounts in their 60s often avoid these surcharges later. A 2022 study by the Employee Benefit Research Institute found that households making strategic Roth conversions between ages 62 and 70 reduced their lifetime Medicare surcharges by an average of $18,000.

State Taxes and IRMAA Interaction

Eleven states levy income taxes on Social Security benefits, which can compound the problem. Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah and Vermont all tax at least a portion of benefits.

A retiree in Connecticut receiving $50,000 in Social Security and $80,000 from pensions could face both state tax and federal IRMAA. Moving to one of the nine states with no income tax, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, Alaska or New Hampshire, does not erase the federal IRMAA calculation because it is based on federal modified adjusted gross income before state taxes.

Still, eliminating the state tax bill frees up cash that can be used for Roth conversions or other planning steps.

Practical Steps to Manage or Avoid Surcharges

Three main strategies help many households. First, conduct Roth conversions in years when income is lower, ideally before required minimum distributions begin. Second, use qualified charitable distributions from IRAs after age 70½; these reduce adjusted gross income without counting as taxable income.

In 2024 the limit for such distributions was $105,000 per person. Third, time the sale of taxable investments so large capital gains do not land in the same year as other income.

A 2023 report from the Medicare Payment Advisory Commission noted that 42 percent of beneficiaries with incomes between $150,000 and $250,000 could have lowered or avoided their 2022 IRMAA through better planning. Retirees should review their Social Security online account each October when the annual notice arrives and compare projected income against the current brackets.

Long-Term Outlook and Possible Changes

Because the IRMAA brackets are not indexed to inflation, more retirees will pay them over time. Between 2010 and 2023 the number of people subject to the highest tier grew from 400,000 to 1.1 million.

Proposals in Congress to adjust brackets for inflation have not passed. The Bipartisan Budget Act of 2015 froze the thresholds until 2020 and then allowed limited increases.

With Medicare trust funds projected to face shortfalls by 2034 according to the latest Trustees Report, pressure to expand IRMAA to more middle-income retirees remains strong. For those now 55 to 65, the prudent step is to run multi-year tax projections that include future Social Security, pensions, investment income and health-care costs.

Software from firms such as RightCapital and MoneyGuidePro can model different Roth conversion ladders and show the net effect on lifetime Medicare premiums.

Real Numbers From Recent Retirees

Consider a teacher who retired in 2024 at age 62 with a $68,000 pension and $22,000 in Social Security. In 2026 her total income of $90,000 keeps her below all surcharges.

Her neighbor, a former sales executive, retired the same year with a $135,000 pension plus $28,000 Social Security and a $12,000 IRA withdrawal. That $175,000 income triggers the second IRMAA tier, adding $4,440 a year in Part B and Part D fees.

Over ten years those extra charges total more than $44,000. The executive could have converted $50,000 from his IRA to a Roth in 2023 while still working part time, paid tax at ordinary rates then, and entered retirement with lower future taxable income.

Medicare IRMAA surcharges are not inevitable for every higher-income retiree. By mapping out income for the next five to ten years and acting while still in your 50s or early 60s, you can often stay below the thresholds or at least limit the time spent paying extra.

The key facts remain simple: two-year look-back, fixed brackets, and rising required distributions all work against you unless you plan ahead. Retirees who run the numbers with a tax advisor or use reliable projection software typically recover the planning cost many times over in lower lifetime Medicare premiums.

Start by pulling your last three tax returns and your latest Social Security statement. Compare those figures against the 2026 brackets posted on Medicare.gov each October.

A few hours of calculation now can protect thousands of dollars of retirement income later.
