Your income plays a big role in what you pay for Medicare Part D. If you make more, you pay more. If your income is lower, you may get help paying for your prescriptions.
Let’s break it down simply: what affects your cost, what IRMAA means, and how programs like Extra Help can reduce your monthly bills.
What Is Medicare Part D?
Medicare Part D covers prescription drugs. You buy it from private companies approved by Medicare. Each plan has its own list of covered drugs and costs, but your income decides if you’ll pay extra.
Part D premiums are made up of two parts:
- The plan’s base premium
- Any extra amount due to your income
What Is IRMAA?
If you earn above a certain amount, you pay more for your Part D plan. This extra cost is called the Income-Related Monthly Adjustment Amount, or IRMAA.
The government looks at your tax return from two years ago to decide this. For 2025, they will check your 2023 income.
If your income is below a set level, you don’t pay IRMAA. But if it’s higher, a surcharge is added to your monthly premium.

2025 Income Brackets for Part D
The higher your income, the higher your extra payment. Here’s a simple breakdown of estimated 2025 income ranges and added monthly IRMAA amounts:
| Filing Status / 2023 Income | Extra Part D Cost per Month |
| Up to $106,000 (single) / $212,000 (joint) | $0 |
| $106,001 – $133,000 / $212,001 – $266,000 | $13.70 |
| $133,001 – $167,000 / $266,001 – $334,000 | $35.30 |
| $167,001 – $200,000 / $334,001 – $400,000 | $57.00 |
| $200,001 – $500,000 / $400,001 – $750,000 | $78.60 |
| Above $500,000 / Above $750,000 | $85.80 |
These numbers can change every year, but they give you a clear idea of how income drives costs.
What Counts as Income?
Medicare uses your modified adjusted gross income (MAGI). It includes:
- Wages and self-employment income
- Pension or retirement withdrawals
- Capital gains, interest, and dividends
- Tax-exempt interest
Your Social Security benefits usually don’t affect this number unless they’re taxable.
If your income drops due to retirement or another life change, you can ask for an IRMAA adjustment.

The Low-Income Subsidy (Extra Help)
If your income is low, you may not pay anything extra. The Low-Income Subsidy, also known as Extra Help, can lower your drug costs.
People who qualify for Extra Help often pay:
- Little or no monthly premium
- No or small deductible
- Only a few dollars for prescriptions
To qualify, your income and assets must fall under certain limits. Even if your income is slightly above, it’s worth applying to some states that offer partial help.
What If Your Income Changes?
Medicare checks your income every year. If your income goes up, your premium may rise too. If it goes down, you can request a review.
You can ask for a lower payment if your income dropped because of:
- Retirement
- Loss of job or business
- Divorce or death of a spouse
- Loss of income-producing property
You’ll need to provide proof when applying for a new IRMAA decision.
How to Lower Your Medicare Drug Costs
Even if you can’t change your income, you can still lower your costs:
- Compare plans every year
- Choose generic drugs
- Use mail-order pharmacy discounts
- Apply for state or local drug-assistance programs
Planning ahead can save hundreds each year.

Your income determines your Medicare Part D premium. Higher income means higher cost through IRMAA, but lower income can bring relief through Extra Help.
