What are the 2026 IRMAA thresholds for Medicare?

For 2026, IRMAA surcharges begin when MAGI exceeds approximately $106,000 (single) or $212,000 (married filing jointly). Thresholds are adjusted annually for inflation. The IRS finalizes IRMAA thresholds each fall for the following year. Check Medicare.gov for the most current brackets.

Can you appeal an IRMAA surcharge caused by a large RMD?

Generally not for a regular RMD — IRMAA appeals are for qualifying life events that caused a permanent reduction in income (retirement, divorce, death of spouse, reduction in work hours). A one-time large RMD that won't recur is unlikely to qualify. However, if the large RMD was a one-time event and income returns to normal, you can request a recalculation in the following appeal year.

Does a QCD reduce IRMAA exposure?

Yes. A Qualified Charitable Distribution is excluded from your taxable income (it appears on Form 1040 line 4a but not 4b), which means it is excluded from MAGI. Using a QCD to satisfy part or all of your RMD directly reduces MAGI and can keep you below an IRMAA threshold.

Scenario

RMD and Medicare IRMAA — How Large Distributions Increase Premiums

How do large Required Minimum Distributions trigger Medicare IRMAA surcharges?

Medicare Part B and Part D premiums are not fixed — they include income-related monthly adjustment amounts (IRMAA) for higher-income beneficiaries. Your IRMAA tier is based on Modified Adjusted Gross Income (MAGI) from two years prior. A large RMD in 2026 could increase Medicare premiums in 2028.

Required Minimum Distributions are included in MAGI and therefore directly affect IRMAA calculations. For 2026, the standard Part B premium applies to individuals with MAGI at or below $106,000 (single) or $212,000 (married). Above those thresholds, surcharges begin. The maximum IRMAA tier (MAGI over $500,000 single or $750,000 married) adds over $4,800 annually to Part B premiums alone.

Planning RMDs with IRMAA in mind — especially Roth conversions, QCDs, and the timing of large distributions — can prevent costly premium spikes.

Key RMD Rules

1IRMAA is based on MAGI from 2 years prior (2026 income affects 2028 Medicare premiums).
22026 IRMAA thresholds (approximate): $106K single / $212K married — standard premium. $133K/$266K, $167K/$334K, $200K/$400K, $500K/$750K — progressive surcharge tiers.
3QCDs reduce MAGI — a QCD does not appear on the taxable income line, reducing IRMAA exposure.
4Roth conversions increase MAGI in the conversion year — model the IRMAA impact before converting.
5You can appeal an IRMAA determination if income dropped due to a life event (retirement, divorce, death of spouse) using Form SSA-44.

Managing RMDs to Stay Below IRMAA Thresholds

Key strategies: (1) Use QCDs for charitable giving — QCDs are excluded from AGI, directly reducing IRMAA exposure. (2) Take IRA distributions before RMD age to reduce the future RMD base — lower balance = lower RMD = lower MAGI in later years. (3) Spread Roth conversions over multiple years to avoid single-year spikes. (4) Time large one-time distributions (IRA liquidation, real estate sale) carefully relative to Medicare enrollment.

Common RMD Mistakes to Avoid

⚠Not modeling the 2-year lookback — a large 2026 RMD affects 2028 Medicare premiums, which many retirees discover only when the premium bill arrives.
⚠Doing a large Roth conversion in the same year as a large RMD, doubling the IRMAA impact.
⚠Not filing an IRMAA appeal after a qualifying life event (e.g., retirement in 2026 reduces 2027 income, but 2026 Medicare is still based on 2024 MAGI).
