2027 Medicare Planning Guide
2027 IRMAA Brackets: What We Know Now — and How to Plan Before the Numbers Drop
The official brackets aren’t out yet. But if your 2025 income was above $109,000, your planning window is already open.
Brackets not yet officially announced — projections insideQuick Answer
The 2027 IRMAA brackets have not been officially announced. CMS typically releases the following year’s Medicare premium surcharges in late October or early November. Based on recent inflation trends, financial planners project the 2027 base threshold will remain near $109,000 for single filers and $218,000 for married couples — based on your 2025 Modified Adjusted Gross Income. The window to plan is open right now.
Every year, thousands of people open a letter from Social Security and discover their Medicare premiums have jumped — based on income from two years ago that no longer reflects their life today.
For 2027 Medicare premiums, that income year is 2025. And while the official brackets won’t be released until fall 2026, the planning you do right now — before those numbers drop — is what separates a surprise from a strategy.
Here’s everything we know, what’s being projected, and what you can do today.
Key Takeaways
- The 2027 IRMAA brackets will not be officially announced until fall 2026 — likely October or November.
- Your 2027 Medicare premiums are based on your 2025 Modified Adjusted Gross Income (MAGI).
- Financial planners project the base threshold will remain around $109,000 single / $218,000 joint.
- The highest bracket cap is legislatively set at $500,000 single / $750,000 joint.
- If your 2025 income was elevated by a one-time event, you may be able to appeal using Form SSA-44.
- The planning window is open now — before CMS makes it official.
Why the 2027 Brackets Aren’t Out Yet
The Centers for Medicare & Medicaid Services (CMS) announces official IRMAA thresholds and premium amounts for the following year in late autumn — typically by early November of the preceding year. That means the 2027 brackets won’t be confirmed until fall 2026.
This isn’t unusual — it happens every year. And it creates a useful window: the time between now and the announcement is when smart planning actually happens. Once the brackets are locked, your options narrow. Right now, they’re still open.
The Two-Year Lookback: Why 2025 Income Matters Right Now
IRMAA uses what’s called a two-year lookback rule. For 2027 Medicare premiums, Social Security will look at your 2025 Modified Adjusted Gross Income — the return you filed in 2026.
That means if you had an elevated income year in 2025 — a business sale, large IRA withdrawal, severance package, or investment gains — Medicare is going to see that number and set your 2027 premiums accordingly. Even if your income has since dropped significantly.
The trap most people miss: You could be retired, living on a careful budget, and still paying IRMAA surcharges in 2027 — because of money you made in 2025 during a very different chapter of your life. The good news is that if your income has genuinely dropped due to a qualifying life event, you can appeal.
Your 2025 income year has already closed, so you can’t go back and change the income Medicare will generally use for your 2027 IRMAA determination. But you can still prepare now by reviewing your 2025 MAGI, understanding where you may fall, and knowing whether a qualifying life-changing event could give you grounds to request a new determination.
Projected 2027 IRMAA Brackets
Because CMS adjusts IRMAA thresholds annually based on inflation (specifically the Consumer Price Index), financial planners use recent trends to project where the 2027 brackets will likely land. These are projections, not official figures — treat them as planning guideposts, not guarantees.
| Single Filer | Married Filing Jointly | Status |
|---|---|---|
| Up to ~$109,000 | Up to ~$218,000 | Standard premium — no IRMAA surcharge Projected |
| Above ~$109,000 | Above ~$218,000 | IRMAA surcharge begins Projected |
| $500,000 and above | $750,000 and above | Top bracket cap under current law Statutory cap under current law |
Source: Financial planning projections based on CMS inflation-adjustment methodology. Top bracket caps reflect current law. Final 2027 IRMAA brackets have not yet been announced. This page will be updated when official figures are released.
The middle brackets — which often create the biggest dollar increase for affected retirees — follow a stepped structure between the base threshold and the top bracket caps. Those projected figures will be added here as estimates become clearer. Official 2027 IRMAA brackets have not yet been announced.

What Counts Toward Your MAGI — and What Doesn’t
Not all income is treated equally when Medicare calculates your IRMAA. Understanding what counts — and what doesn’t — is one of the most powerful planning tools you have.
What IS counted in your MAGI:
- Wages, salaries, and self-employment income
- Traditional IRA and 401(k) withdrawals
- Required Minimum Distributions (RMDs)
- Capital gains (from stocks, real estate, business sales)
- Taxable Social Security benefits
- Pension and annuity income
- Tax-exempt municipal bond interest
What is NOT counted in your MAGI:
- Qualified Roth IRA withdrawals
- Qualified Charitable Distributions (QCDs) from IRAs — available after age 70½, up to $111,000 per individual in 2026
- Life insurance proceeds
- Inheritances (in most cases)
- Health Savings Account (HSA) withdrawals used for qualified medical expenses
The Roth advantage: Qualified Roth IRA withdrawals don’t count toward MAGI — which means they don’t trigger IRMAA. For people approaching Medicare, this is one of the strongest arguments for Roth conversions in the years before age 65. Talk with a tax professional about whether your situation makes this strategy worth pursuing.
How to Plan Before the Official Numbers Drop
The income year that generally determines your 2027 IRMAA—2025—is already behind us. But there is still plenty you can do before 2027: understand your 2025 MAGI, estimate your potential surcharge, prepare for the official brackets, and know whether you may qualify for an appeal if your income has since dropped. Here’s where to focus your energy.
Review your 2025 income picture
Did you have a high-income event in 2025 — a sale, large withdrawal, severance, or windfall? That number is what Medicare will see for 2027. Know it before Social Security does.
Consider Roth conversion timing
If you’re planning for future Medicare years, converting traditional IRA funds to Roth may reduce future RMDs that count toward MAGI. A Roth conversion made in 2026 will not change the 2025 income generally used for your 2027 IRMAA determination, and the conversion itself can increase MAGI for the year it occurs. Talk with a qualified tax professional before making a conversion.
Explore Qualified Charitable Distributions
If you’re 70½ or older, QCDs let you donate directly from your IRA to an eligible charity — up to $111,000 per person in 2026 — without the distribution counting toward your MAGI. That means no IRMAA trigger on that income.
Manage capital gains timing
If you’re planning to sell investments, consider whether the timing of those gains can be spread across tax years to avoid pushing you into a higher IRMAA bracket.
Know your appeal rights in advance
If your 2025 income was high due to a one-time event and your income has since dropped significantly, you may qualify to appeal your 2027 IRMAA using Form SSA-44.
Build a forward-looking income forecast
Work with a financial or tax professional to map your expected income for 2026 and future years. That can help you anticipate future IRMAA exposure and make more informed decisions about withdrawals, conversions, capital gains, and other taxable income.
These are general planning concepts. Consult a qualified tax professional or financial advisor before making income or investment decisions.
A Closer Look: How Qualified Charitable Distributions Work
QCDs are one of the most effective — and underused — tools for reducing IRMAA exposure. Here’s what you need to know before using one.
For 2026, the maximum QCD limit is $111,000 per person, up from $108,000 in 2025. Married couples can each give up to that amount from their own IRAs. To qualify, you must be age 70½ or older when the distribution is made.
QCDs can generally come from traditional, rollover, and inherited IRAs, and from SEP or SIMPLE IRAs — but only if those plans are not receiving current employer contributions. The funds must go directly from the IRA custodian to an eligible charity. If the money touches your personal bank account first, it becomes fully taxable.
QCDs are excluded from gross income, can satisfy all or part of your Required Minimum Distribution, and may help reduce AGI-based costs like IRMAA and Social Security taxation. For 2026, up to $55,000 of your QCD limit can be used as a one-time election to fund certain split-interest gifts — such as a charitable remainder trust or charitable gift annuity.
Important exclusions: Donor-advised funds and most private foundations do not qualify to receive QCDs. Always confirm with your IRA custodian and a tax advisor before making the transfer.
2027 IRMAA Brackets for Married Couples Filing Jointly
If you and your spouse both have Medicare, IRMAA applies to each of you individually — but the income threshold that triggers it is based on your combined household income from your joint tax return.
For 2026, the joint filing threshold starts at $218,000 in MAGI — exactly double the single filer threshold of $109,000. Financial planners project the 2027 thresholds may remain at similar levels, pending the official CMS announcement in fall 2026.
Key point for couples: Each spouse pays their own IRMAA surcharge separately. If both of you are on Medicare and your joint income exceeds the threshold, both Part B premiums and both Part D premiums are affected — not just one. That can mean a significant combined monthly increase depending on which bracket you land in.
Married Filing Separately — A Different Set of Rules
If you are married but file your taxes separately, the IRMAA rules are significantly stricter — and catch many people off guard.
For 2026, married individuals filing separately who lived with their spouse at any point during the tax year face a compressed bracket structure. The surcharge kicks in at a much lower income level than it does for joint filers, and the thresholds jump quickly to the highest bracket.
This filing status is rarely advantageous from a Medicare premium standpoint. If you are considering filing separately for any reason — including managing student loan repayment, protecting income-based benefits, or other financial planning purposes — factor in the potential IRMAA impact before deciding.
Planning tip for couples: If one spouse had significantly higher income in 2025 due to a one-time event — a business sale, large IRA withdrawal, or severance — and the other spouse’s income was modest, your joint MAGI still determines IRMAA for both of you. If that combined figure pushes you into a surcharge bracket and your income has since dropped, you may qualify to appeal using Form SSA-44. See the appeal section below for qualifying events.
When Both Spouses Are on Medicare
This is the scenario that surprises couples most. Many assume IRMAA is a single line item — one surcharge per household. It isn’t. Each spouse’s Part B premium and Part D premium are adjusted independently based on the same joint income figure.
For a couple in the first IRMAA bracket, that means the standard Part B premium increase applies twice — once for each person. Multiply that across Part D as well, and the combined annual impact can be substantial. Understanding this before you hit Medicare age — not after the letter arrives — is exactly the kind of planning that makes a real difference.
Your 2027 IRMAA Timeline
Understanding the sequence of events helps you know exactly when to act and what to watch for.
2025 — Income year that determines 2027 IRMAA
Every dollar of MAGI you earn in 2025 is what Social Security will use to set your 2027 Medicare premiums. This is where planning has the most impact.
Early 2026 — File your 2025 tax return
Your 2025 MAGI is reported on the return you file in spring 2026. Social Security receives this data from the IRS automatically.
Fall 2026 — CMS announces official 2027 brackets
Typically in October or November, CMS releases the official IRMAA income thresholds and premium amounts for the following year. This page will be updated when that happens.
Late 2026 — IRMAA determination letters go out
Social Security sends letters to beneficiaries affected by IRMAA, informing them of their 2027 surcharge based on 2025 income.
January 1, 2027 — New premiums take effect
Your updated Medicare Part B and Part D premiums — including any IRMAA surcharge — begin with your January 2027 coverage.
If Your Income Has Already Dropped: The SSA-44 Appeal
One of the most important things to know about IRMAA is that it isn’t always permanent — and it doesn’t have to be accepted without question.
If you experienced a qualifying life-changing event that reduced your income, you can file Form SSA-44 to appeal your IRMAA determination and request that Medicare use more recent income data instead of the two-year-old figure on file.
Qualifying life events for an SSA-44 appeal include:
- Retirement or reduction in work hours
- Death of a spouse
- Divorce or marriage
- Loss of pension income
- Loss of income-producing property
- Employer settlement payment that was a one-time event
Important: File your appeal as soon as the life change occurs — don’t wait for the new year. Include documentation (retirement letter, divorce decree, death certificate, etc.) and submit to your local Social Security office. In-person submissions typically move faster. Download Form SSA-44 here.
Appealing IRMAA isn’t a workaround — it’s your legal right. Medicare premiums should reflect where you actually are in life, not a snapshot from two years ago.
For a full walkthrough of the appeal process, see the 2026 IRMAA guide, which includes a step-by-step breakdown of Form SSA-44 with qualifying event examples.
Frequently Asked Questions
When will the 2027 IRMAA brackets be officially announced?
CMS typically releases the following year’s Medicare premium surcharges in late October or early November. The 2027 IRMAA brackets are expected in fall 2026. This page will be updated when official figures are confirmed.
What income year determines my 2027 IRMAA?
Your 2027 Medicare premiums will be based on your Modified Adjusted Gross Income (MAGI) from your 2025 tax return — the return you file in spring 2026. This is called the two-year lookback rule.
What are the projected 2027 IRMAA thresholds?
Financial planners project the base threshold will remain near $109,000 for single filers and $218,000 for married couples filing jointly — consistent with 2026. The highest bracket remains legislatively capped at $500,000 for single filers and $750,000 for joint filers. These are projections until CMS confirms official figures in fall 2026.
Do Roth IRA withdrawals count toward IRMAA?
No. Qualified Roth IRA withdrawals do not count toward your MAGI and therefore don’t trigger IRMAA. This is one of the key reasons Roth conversions before Medicare eligibility can be a valuable long-term planning strategy.
Can I appeal my 2027 IRMAA if my income has dropped?
Yes — if you experienced a qualifying life-changing event such as retirement, divorce, death of a spouse, or a significant income reduction, you can appeal using Form SSA-44. File as soon as the life change occurs and include supporting documentation.
Does IRMAA apply to both Part B and Part D?
Yes. IRMAA surcharges apply separately to Medicare Part B and Medicare Part D. If your income exceeds the threshold, you pay an additional amount on top of both your Part B premium and your Part D plan premium.
The Window Is Open Now
The 2027 IRMAA brackets haven’t been announced yet — and that’s actually the point. The time between now and the official announcement is when planning makes the most difference.
Once the letter arrives, your options become reactive. Right now, they’re proactive. Whether that means reviewing your 2025 income, exploring a Roth conversion, timing a capital gains event, or simply knowing your appeal rights before you need them — the best move is always the one you make before you’re surprised.
This page will be updated the moment CMS releases official 2027 figures. In the meantime, if you have questions about how IRMAA applies to your specific situation, that’s exactly the kind of conversation worth having with someone who knows Medicare.
