What are the estimated Irmaa brackets for 2028?
2026 2027 2028 Medicare IRMAA Premium MAGI Brackets outlines that your 2028 Medicare IRMAA (Income-Related Monthly Adjustment Amount) brackets will be determined by your 2026 Modified Adjusted Gross Income (MAGI).
Projected 2028 MAGI Thresholds
Official CMS brackets for 2028 will be announced in late 2027, but current financial projections estimate the tiers as follows:
- Tier 1 (No Surcharge):
- Single: Up to ≈$113,000 – $114,000

- Tier 2:
- Single: ≈$114,001 – $143,000

- Tier 6 (Top Tier):
- Single: $500,000+
- Married Filing Jointly: $750,000+
Key Planning Facts
- The Cliff Effect: Crossing an IRMAA threshold by even $1 triggers the entire surcharge for that tier; it is not a marginal tax bracket.
- Income Sources: MAGI includes adjusted gross income plus tax-exempt municipal bond interest.
- Management: Actions taken during 2026 (such as capital gains realization or Roth conversions) directly lock in your 2028 surcharge exposure.
What are the Irmaa brackets for 2029?
Official Medicare IRMAA (Income-Related Monthly Adjustment Amount) brackets for 2029 are not yet finalized by the Centers for Medicare & Medicaid Services (CMS), as official numbers are typically released in late autumn of the prior year (2008/2028 data pattern applies, meaning 2029 official numbers release in late 2008? No, late 2028). However, 2029 IRMAA surcharges will be determined using your 2027 federal tax return Modified Adjusted Gross Income (MAGI).
How 2029 IRMAA Works
- The Lookback Year: Your 2027 MAGI (Adjusted Gross Income plus tax-exempt interest) sets your 2029 surcharge.
- The Baseline Structure: IRMAA uses five distinct high-income tiers above the standard base premium threshold.
- Projections: Based on current inflationary indexing trends, the standard baseline thresholds for 2027 sit at modified income cutoffs of $112,000 for single filers and $224,000 for married couples filing jointly, with 2029 expected to track slightly higher pending final inflation adjustments.
What will the Irmaa bracket be for 2027?
Official 2027 IRMAA brackets will not be finalized and released by the Centers for Medicare & Medicaid Services until late October or November 2026.
However, based on current inflation trends and the Medicare Trustees Report, independent financial trackers project the 2027 brackets and surcharges based on your 2025 Modified Adjusted Gross Income (MAGI).
Projected 2027 IRMAA Income Brackets
| Projected 2025 MAGI (Single) | Projected 2025 MAGI (Joint) | Projected Part B Surcharge | Projected Part D Surcharge |
|---|---|---|---|
| $112,000 or less | $224,000 or less | Part B base only | Part D base only |
| $112,001 to $142,000 | $224,001 to $284,000 | $83.70 plus base | $15.40 plus base |
| $142,001 to $177,000 | $284,001 to $354,000 | $209.40 plus base | $39.70 plus base |
| $177,001 to $212,000 | $354,001 to $424,000 | $335.10 plus base | $64.00 plus base |
| $212,001 to $499,999 | $424,001 to $749,999 | $460.70 plus base | $88.30 plus base |
| $500,000 or more | $750,000 or more | $502.60 plus base | $96.40 plus base |
Note: The highest tier ($500,000+ single / $750,000+ joint) is frozen by federal law through 2028.
Key Rules to Keep in Mind
- The Lookback Period: Your 2027 Medicare surcharges are determined strictly by your 2025 tax return (AGI plus tax-exempt interest).
- The Cliff Effect: IRMAA operates as a strict cliff rather than a progressive bracket. Exceeding a threshold by even $1 means paying the surcharge for the entire tier.
- Appeals: If your 2025 income was high due to a one-time event or if you have experienced a life-changing event (like retirement or work reduction) since 2025, you can appeal your surcharge using Form SSA-44.
Do husband and wife both pay Irmaa?
Yes, both husband and wife on Medicare must pay the IRMAA surcharge if their combined joint income crosses the government limit.
How IRMAA Works for Married Couples
- Per Person Charge: Medicare charges IRMAA to each individual person, not just once to the household.
- Shared Income: The Social Security Administration looks at your combined Modified Adjusted Gross Income (MAGI) from a joint tax return.
- Full Surcharge Each: If your joint income goes over the limit, both spouses pay the full extra fee separately. It is not split between them.
- No Medicare, No Fee: If only one spouse is enrolled in Medicare, only that enrolled spouse pays the IRMAA surcharge.
Key Numbers for 2026
- Income Limit: For 2026, joint income over $218,000 (based on your 2024 tax return) triggers IRMAA.
- The Cliff Effect: If you go over the limit by even one dollar, both spouses must pay the full surcharge for that tier for the entire year.
- Part B and D: The extra fee is added to both your Part B (medical insurance) and Part D (prescription drug) monthly costs.
How much will Medicare Part B premium be in 2027?
The standard Medicare Part B monthly premium is projected to be $209.50 in 2027. This represents an increase of $6.60 (about 3.25% to 3.5%) from the 2026 rate of $202.90.
These figures originate from the latest Medicare Trustees Report projections. The Centers for Medicare & Medicaid Services (CMS) typically announces the finalized official amounts in late autumn.
Additional Projected 2027 Medicare Part B Costs
- Annual Deductible: Projected to rise to $292, up $9 from $283 in 2026.
- High-Income Surcharges (IRMAA): Beneficiaries with higher modified adjusted gross incomes (MAGI) from two years prior (2025 tax returns) will pay higher premiums. The projected 2027 IRMAA income brackets start for single filers with a MAGI above $112,000 and joint filers above $224,000, adding a monthly Part B surcharge ranging from $83.70 to $502.60 on top of the base premium.

Projected 2028 IRMAA Tiers (Estimates)

The standard 2026 Medicare Part B premium is $202.90 per month. Exceeding the base thresholds adds monthly surcharges for both Part B and Part D across five distinct tiers.
2026 IRMAA Brackets and Premiums
| Single MAGI (2024) | Joint MAGI (2024) | Part B Surcharge | Total Part B Premium | Part D Surcharge |

| ≥ $500,000 | ≥ $750,000 | $487.00 | $689.90 | $91.00 |
Key Details to Remember
- Two-Year Lookback: Your 2026 surcharges rely on the tax data from your 2024 tax return (AGI plus tax-exempt interest).
- Cliff Brackets: Going over a threshold by even a single dollar means you pay the surcharge for that entire tier.
- Appeals: If you experienced a qualifying life-changing event (such as retirement or work stoppage), you can appeal using Medicare IRMAA Brackets & Income Limits guidelines via Form SSA-44.

What is the highest Medicare premium I can expect per month?
The highest standard monthly cost you can expect for Medicare Part B is $689.90 if you have a high income that triggers maximum IRMAA (Income-Related Monthly Adjustment Amount) surcharges.
Maximum Monthly Premiums by Part
- Part A (Hospital Insurance): Up to $565 per month if you or your spouse did not work long enough to qualify for premium-free Part A (under 30 quarters of Medicare taxes).
- Part B (Medical Insurance): A standard premium of $202.90, which can rise as high as $689.90 per month for high-income earners.
- Part D (Prescription Drug Coverage): Varies by private plan, but high-income surcharges add an extra $91.00 per month on top of your plan's standard monthly premium.
- Part C (Medicare Advantage) & Medigap: These are private insurance options with variable pricing (averaging around $14 to over $200 per month), but you must still pay your Part B premium to keep them active.
Who pays 75% of Medicare Part B?
The U.S. Federal Government pays approximately 75% of the total cost for Medicare Part B through general revenues.
How Part B Financing Works
- Government Share: The federal government subsidizes about 75% of the general program and premium costs for most enrollees.
- Beneficiary Share: You pay the remaining 25% through your standard monthly Part B premium.
- High-Income Exceptions: If your modified adjusted gross income is above a certain threshold, you pay a larger share (ranging from 35% to 85%) through an extra charge called the Income-Related Monthly Adjustment Amount (IRMAA).
