For many retired California educators, Medicare planning feels simple at first. You turn 65, enroll at the right time, choose the coverage you need, and prepare for monthly premiums. But higher-income retirees may face an added cost that can surprise them: IRMAA.
IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra monthly surcharge added to Medicare Part B and Medicare Part D premiums when your income is above certain limits. For retired educators, this can matter because income may come from several places, including pension payments, supplemental retirement savings, taxable account withdrawals, interest, dividends, and other retirement income sources.
This is why Medicare planning should not be separated from retirement income planning. A retired teacher or public school employee may feel financially ready, but a poorly timed withdrawal or taxable income spike can make Medicare premiums higher two years later. Working with Peak Solutions Financial can help California educators understand how retirement income choices may affect long-term cash flow, taxes, and healthcare costs.
What Is IRMAA and Why Does It Matter for Retired Educators?
IRMAA is an added Medicare premium amount for higher-income beneficiaries. It applies to:
- Medicare Part B, which covers doctor visits, outpatient care, and many medical services
- Medicare Part D, which helps with prescription drug coverage
IRMAA does not apply to Medicare Part A for most retirees.
The important part is that IRMAA is based on income, not assets. A retired educator may have a pension, savings, and other accounts, but the surcharge is triggered by modified adjusted gross income, often called MAGI. For Medicare IRMAA purposes, MAGI generally includes adjusted gross income plus tax-exempt interest income.
This means IRMAA can be affected by income decisions such as:
- Taking large withdrawals from retirement accounts
- Selling investments with capital gains
- Receiving pension income
- Taking required minimum distributions
- Earning interest or dividends
- Completing taxable account conversions
- Filing taxes jointly, separately, or individually
For educators who spent decades building retirement security, IRMAA can feel frustrating because it reduces monthly flexibility. It is not just a tax issue. It is a retirement income issue.
How Are IRMAA Surcharges Calculated?
IRMAA uses income from two years earlier. For example, 2026 Medicare premiums are generally based on the federal tax return from tax year 2024. This two-year lookback can create confusion because your current income may be lower than the income used to set your premium.
For 2026, the standard Medicare Part B premium is $202.90 per month. If your MAGI is above the IRMAA threshold, you may pay an additional amount on top of that standard premium. For individuals, IRMAA begins above $109,000 of MAGI. For married couples filing jointly, IRMAA begins above $218,000 of MAGI.
The 2026 Part B surcharge ranges from $81.20 per month to $487.00 per month, depending on the income bracket. The Part D surcharge ranges from $14.50 per month to $91.00 per month, in addition to the plan premium.
For a retired California educator, this can create a meaningful annual cost. If both spouses are on Medicare and both are subject to IRMAA, the surcharge can apply to each person. That is why a household income plan matters.
Why Can California Educators Be More Exposed to IRMAA?
California educators may be more exposed to IRMAA because retirement income can come from multiple coordinated sources. A pension may provide dependable income, but it may not be the only source of cash flow.
A retired educator may also use:
- 403(b) accounts
- 457(b) accounts
- Taxable savings
- Bank interest
- Investment income
- Spousal income
- Part-time work
- Deferred compensation
- Required minimum distributions later in retirement
Peak Solutions Financial explains that educators face unique retirement challenges, including pensions, service credit rules, supplemental accounts, and benefit decisions that all affect retirement income. Their retirement planning services focus on turning these moving parts into a clear plan.
This is important because a Medicare premium decision is rarely isolated. It can connect to when you retire, when you draw income, how you use supplemental savings, and how much taxable income you create in a given year.
How Can Pension Income Affect Medicare Premiums?
Pension income can provide stability, but it also counts as income for tax purposes. If your pension income, taxable withdrawals, dividends, interest, and other taxable income push your MAGI above an IRMAA threshold, your Medicare Part B and Part D premiums may increase.
This does not mean pension income is bad. For many retired educators, it is the foundation of retirement. But it does mean pension income should be coordinated with other sources. For example, taking a large withdrawal from a supplemental account in the same year as pension income could push your MAGI higher than expected.
Educators planning their retirement timeline may want to review Peak’s article on transition-year income. The transition year can be especially important because income may shift from salary to pension, savings withdrawals, or bridge income.
How Can Supplemental Retirement Savings Trigger IRMAA?
Supplemental retirement savings can give educators more control, but they also need careful timing. Withdrawals from some retirement accounts may increase taxable income. If a large withdrawal happens in a year used for Medicare’s two-year lookback, it can raise Medicare premiums later.
This can happen when a retired educator uses supplemental savings to:
- Cover income before full pension benefits begin
- Pay off debt
- Help family members
- Make a major purchase
- Build a cash reserve
- Convert taxable retirement funds
- Prepare for future required minimum distributions
Peak’s article on supplemental retirement savings fits naturally with IRMAA planning because the timing of withdrawals can affect both cash flow and Medicare premium exposure.
Educators may also want to compare how different account types fit together. Peak’s resources on 403(b) contributions, 457(b) plans, and Roth 403(b) vs. Traditional 403(b) can help frame the bigger planning conversation.
Can a Retirement Income Floor Help Manage IRMAA Risk?
A retirement income floor is the dependable income you can count on for essential expenses. For California educators, this may include pension income and carefully planned supplemental income sources.
A clear income floor helps because it separates needs from flexible spending. If your basic lifestyle is covered, you may have more control over when and how to draw from other accounts. That control can help reduce the chance of creating unnecessary taxable income in one year.
Peak’s article on building a retirement income floor can be useful for educators who want to connect pension income, supplemental savings, and spending needs. IRMAA planning fits into this because Medicare premiums are part of retirement expenses.
What Is a Pension Bridge Strategy and How Can It Affect IRMAA?
A pension bridge strategy is a plan for covering income needs during a gap period, often before full pension benefits or other retirement income sources begin. This can be helpful, but it must be designed carefully.
If a bridge strategy relies too heavily on taxable withdrawals, it may increase MAGI. If that income year is later used for Medicare IRMAA calculations, the retiree may face higher premiums.
That does not mean bridge strategies should be avoided. It means they should be coordinated with Medicare timing, tax planning, and income expectations. Peak’s article on a pension bridge strategy is a good internal resource for educators who want to understand how temporary income planning may fit into a larger retirement plan.
Can IRMAA Be Reduced After Retirement?
In some cases, yes. If your income has gone down because of a qualifying life-changing event, you may be able to request a new IRMAA decision. Common examples include retirement, reduction in work hours, marriage, divorce, or the death of a spouse.
This is very relevant for educators. A teacher may have high income in the final working year because of salary, unused leave payouts, deferred compensation, or other taxable income. Two years later, Medicare may use that higher income to calculate IRMAA, even though the retiree’s current income is lower.
If that happens, the retiree may be able to file the proper request and provide documentation. This is where careful records matter. Keep copies of retirement letters, tax returns, income estimates, and any documents that show the income change.
What Should Higher-Income Retired Educators Review Before Medicare Enrollment?
Before enrolling in Medicare, higher-income California educators should review the full retirement picture. The goal is not to avoid income. The goal is to understand how income timing affects premiums, taxes, and long-term cash flow.
Important items to review include:
- Expected pension income
- Filing status
- Current and future supplemental withdrawals
- Taxable investment income
- Required minimum distribution timing
- Medicare enrollment timeline
- Part B and Part D premium exposure
- One-time income events
- Spousal income
- Possible life-changing event documentation

How Can Peak Solutions Financial Help Educators Plan Around IRMAA?
Peak Solutions Financial can help educators look at IRMAA as one part of the full retirement income plan. This matters because IRMAA is not only about Medicare. It is connected to pensions, supplemental savings, tax timing, income distribution, and household cash flow.
A good planning conversation may include:
- When to retire
- How pension income fits into monthly needs
- Which accounts to use first
- How to avoid unnecessary income spikes
- How to prepare for Medicare enrollment
- How to plan for healthcare-related expenses
- How to coordinate with licensed tax professionals when needed
The best time to think about IRMAA is before the income year that Medicare will use. Since Medicare looks back two years, waiting until the premium notice arrives may limit your options. Planning earlier gives retired educators more room to make thoughtful choices.
What Are the Most Common IRMAA Mistakes to Avoid?
Higher-income retired educators should be careful with these common mistakes:
- Taking a large taxable withdrawal without checking Medicare impact
- Forgetting that Medicare uses a two-year income lookback
- Assuming current income is the only income that matters
- Ignoring Part D surcharges
- Planning pension income without reviewing supplemental savings
- Missing the chance to request a lower IRMAA after a qualifying income drop
- Treating Medicare planning and retirement planning as separate decisions
IRMAA should not cause panic. But it should be part of the plan, especially for educators with strong pensions, savings, or household income.
Why Should IRMAA Be Part of a Retirement Income Plan?
IRMAA can quietly increase healthcare costs for higher-income retired California educators. Since it is based on MAGI and uses a two-year lookback, the best planning often happens before Medicare premiums are calculated.
A strong retirement plan should answer more than, “How much income do I have?” It should also answer, “When should I take income, from which source, and what will it affect?”
For educators who want more clarity, Peak Solutions Financial offers retirement-focused planning built around California educators, public employees, pension decisions, supplemental savings, and long-term income confidence. IRMAA is only one part of retirement, but it is an important part to understand before it becomes an unexpected monthly cost.
