IRMAA is an income-related adjustment to Medicare Part B and Part D premiums. Planning considers income timing, taxes and health coverage costs; savings are not assured. Brett Henderson at SWE90 provides professional guidance. Coordinate tax decisions with your tax advisor.
Key Takeaways
Income timing can affect Medicare premiums as well as income taxes.
- ✓
IRMAA MAGI includes adjusted gross income plus tax-exempt interest.
- ✓
A fiduciary financial advisor has a duty to act in your best interests when providing investment advice.

IRMAA Income Thresholds
For 2026, IRMAA generally uses 2024 tax-return MAGI (2023 if unavailable). It starts above $109,000 for single filers or $218,000 for joint filers. Married-filing-separately rules depend on living arrangements; see SSA tables.
Planning Considerations
- Model taxable Roth conversions: they raise current MAGI and may affect premiums two years later.
- Eligible QCDs excluded from IRA income may help manage MAGI; requirements and limits apply.
- Tax-exempt municipal interest is added to IRMAA MAGI; it does not avoid IRMAA.
- Coordinate capital gains, withdrawals and coverage costs; no sequence assures lower premiums.
Can I appeal my IRMAA determination?
A qualifying life-changing event with reduced income may support a new determination using SSA-44 and evidence. Other appeals follow the notice instructions; relief is not automatic. See page 5.

Tax planning can help manage your lifetime tax burden. Roth conversions, withdrawal sequencing and tax-loss harvesting can help save taxes over time, depending on your individual circumstances.
How Do Different Strategies Compare?
Traditional IRA / 401(k): Withdrawals are generally taxable except for after-tax basis. RMD timing depends on birth year and account type; certain current-employer plans permit retirement deferral, with exceptions. Roth IRA / Roth 401(k): Qualified withdrawals are tax-free. Neither requires lifetime RMDs for the owner; beneficiary rules differ.
Taxable brokerage: Income and realized gains may be taxable; withdrawals are not all taxed at capital-gains rates.
HSA: Qualified medical withdrawals are tax-free. Other withdrawals may be taxable and subject to additional tax. Withdrawal order depends on your circumstances; no sequence is best for everyone.
Frequently Asked Questions
How can I reduce my tax burden in retirement?
Consider withdrawal timing, eligible deductions and tax-loss harvesting with a tax professional. A strategy should reflect your income, cash needs and Medicare premiums. A fiduciary financial advisor has a duty to act in your best interests when providing investment advice.
Should I do a Roth conversion?
A Roth conversion generally includes its taxable portion in current income and may raise IRMAA two years later. Qualified Roth withdrawals generally are tax-free and do not increase AGI. Compare current costs with possible future RMD and premium effects; inherited-account and qualification rules apply.
What are the tax implications of Social Security benefits?
Up to 85% of Social Security benefits may be taxable depending on your combined income. Strategic planning around income sources can help minimize the tax impact on your Social Security benefits.
What Tax Planning Actions Should You Prioritize?
Effective tax planning requires proactive strategies implemented throughout the year, not just during tax season. Consider these priority actions:
- Review your withholding and estimated payments: The IRS Tax Withholding Estimator can help you determine if your current withholding is appropriate to avoid surprises at tax time.
- Evaluate Roth conversion opportunities: Compare current and potential future taxes. The taxable portion of a conversion is income; qualified Roth distributions are tax-free. Review the amount and withdrawal rules with your tax advisor.
- Harvest tax losses: Review whether selling investments at a loss to offset gains fits your circumstances and applicable tax rules.
- Review retirement contributions: Pre-tax workplace contributions may reduce taxable wages. IRA deductibility depends on eligibility, income and workplace-plan coverage. Roth contributions are not deductible.
- Review charitable giving: Discuss whether bunching donations or using a donor-advised fund fits your goals. Deductibility depends on eligibility, limits and whether you itemize.
Effective tax planning can help individuals and families identify opportunities to reduce their tax burden and improve after-tax outcomes.
How to Create a Tax-Efficient Retirement Plan: Step-by-Step
Implementing a tax-smart strategy requires a systematic approach:
- 1. Step 1: Map your income sources. Identify all current and projected retirement income streams, including Social Security, pensions, 401(k)/IRA distributions, and taxable investment income.
- 2. Step 2: Estimate your future tax bracket. Project your retirement income to determine which federal and state tax brackets you will likely fall into, using resources from the IRS.
- 3. Step 3: Evaluate Roth conversions. Compare the taxable conversion amount, available funds to pay taxes and potential future tax treatment. Savings are not assured.
- 4. Step 4: Evaluate tax-loss harvesting. Review whether realizing investment losses fits your circumstances and applicable tax rules with your tax advisor.
- 5. Step 5: Plan withdrawals. Compare account tax treatment, required distributions, cash needs and other circumstances. There is no single withdrawal order appropriate for everyone.
- 6. Step 6: Review charitable options. Ask your tax advisor whether you qualify for a direct IRA-to-charity distribution and how its rules and limits apply to any required distribution.
- 7. Step 7: Review annually with your advisors. An annual review helps support informed decisions as tax laws and circumstances change; it cannot assure savings or prevent every mistake.
Tax-efficient retirement planning may help reduce the taxes you pay throughout retirement, depending on your individual circumstances. Book your tax strategy session.

Medicare Premium and Review Details (2026) The standard Part B premium is $202.90 monthly. Part B IRMAA is added to that base; Part D IRMAA is a separate adjustment added to the drug plan premium. Do not confuse an adjustment with the total premium. SSA-44 addresses specified events with reduced income, such as work stoppage/reduction, marriage, divorce or a spouse's death; evidence is required. A voluntary Roth conversion alone is not a qualifying life-changing event. Follow your notice for reconsideration deadlines or contact SSA about tax-data errors.
