Understanding Medicare IRMAA in 2025
The Income-Related Monthly Adjustment Amount (IRMAA) is an additional charge added to your Medicare Part B and Part D premiums if your income exceeds certain thresholds. This surcharge affects approximately 7% of Medicare beneficiaries with higher incomes.
How IRMAA Works
- 2-Year Lookback: 2025 IRMAA is based on your 2023 tax return
- Automatic Determination: Social Security receives income data from the IRS
- Annual Recalculation: IRMAA is recalculated each year based on most recent tax data
- Cliff Effect: Going $1 over a bracket threshold increases premiums significantly

Calculating Your Modified Adjusted Gross Income (MAGI)
Your MAGI for IRMAA purposes is calculated differently than for other tax purposes. Here's how to determine your IRMAA MAGI:
IRMAA MAGI Formula:
- Start with your Adjusted Gross Income (AGI) from Form 1040, line 11
- Add back any tax-exempt interest income (Form 1040, line 2a)
- Add back excluded foreign earned income (Form 2555)
- Add back EE bond interest used for education (Form 8815)
- The total is your MAGI for IRMAA purposes
Income That Counts:
- Wages and self-employment income
- Social Security benefits
- Pension and retirement distributions
- Investment income
- Rental income
- Capital gains
Income That Doesn't Count:
- Roth IRA distributions
- Life insurance proceeds
- Gifts and inheritances
- Veterans benefits
- Medi-Gap reimbursements
- Return of principal
Strategies to Reduce or Avoid IRMAA
Proactive Income Management
Before Retirement
- Maximize 401(k)/403(b) contributions

During Retirement
- Use QCDs for charitable giving (age 70½+)

- Manage capital gains timing
- Consider installment sales for property
- Bundle or defer income when possible
Advanced Planning Techniques
Qualified Charitable Distributions (QCDs)
Direct transfers from IRA to charity (up to $100,000) don't count toward MAGI and satisfy RMDs.
Tax-Loss Harvesting
Sell losing investments to offset gains and reduce overall taxable income by up to $3,000.
Income Smoothing
Spread large income events over multiple years to stay below IRMAA thresholds.

Frequently Asked Questions
When will I be notified about IRMAA?
Social Security typically sends IRMAA determination notices in late November or December for the following year. You'll receive a notice if you owe IRMAA.
Can IRMAA change during the year?
Yes, if you experience a qualifying life-changing event or if Social Security receives updated tax information. You can also request a new determination if your circumstances change.
Do both spouses pay IRMAA?
Yes, if both spouses are on Medicare and your combined income exceeds the thresholds, each spouse pays their own IRMAA surcharge.
Is IRMAA permanent?
No, IRMAA is recalculated annually based on your most recent tax return. If your income decreases, your IRMAA can be reduced or eliminated.
How is IRMAA collected?
IRMAA is typically deducted from your Social Security benefits. If you don't receive Social Security, you'll be billed quarterly by Medicare.
