How Does Income Impact Medicare Costs?
When planning your health care costs under Medicare, your income plays a critical role in determining what you’ll pay. Medicare uses your tax-reported income to calculate premiums for Medicare Part B and Part D, applying specific income thresholds for individuals and couples filing jointly or separately.
Depending on your income level, you may be required to pay an Income-Related Monthly Adjustment Amount (IRMAA), which is an additional charge on top of standard premiums for both Part B and Part D. These income thresholds and adjustment amounts are subject to annual changes.
For 2025, individuals with a tax-reported income above $106,000 or couples filing jointly with incomes above $212,000 will incur these additional costs.
Medicare Part B Costs Based on Income
Understanding Part B Premiums
Medicare Part B covers outpatient services like doctor visits, preventive care, and medical equipment. While standard premiums apply to most people, higher earners are subject to IRMAA, which increases monthly costs.
Income Thresholds and Monthly Premiums for 2025
Your Part B premiums are determined by your adjusted gross income (AGI) from two years prior. Below is the breakdown based on your filing status:
For Individual and Joint Tax Filers
| Taxable Income (Individual) | Taxable Income (Joint) | Total Monthly Part B Premium |

Managing Medicare Costs: Tips and Considerations
Using a Health Savings Account (HSA)
If you have an HSA, it can help offset Medicare expenses. HSA funds can be used for:
- Medicare Part B and Part D premiums.
- Out-of-pocket costs, such as copayments and deductibles.
Learn more about HSA and Medicare compatibility on Medicare.gov.
Employer Health Coverage
If you or your spouse have employer-provided health coverage that qualifies as creditable, you may delay Medicare enrollment. This option is particularly useful if your employer’s health plan is more cost-effective than Medicare premiums.
Find out more about delaying Medicare at the Medicare Eligibility and Premiums Guide.
