How Medicare Premiums Are Determined Based on Your Income

For most people enrolling in Medicare when they turn 65, the standard premium for Part B medical coverage applies. In 2023, the standard monthly premium for Medicare Part B is $ 164.90.

However, about 7% of Medicare beneficiaries pay more than the standard premium based on their income. Higher-income enrollees pay an income-related monthly adjustment amount (IRMAA) in addition to their standard premium.

But how exactly does Medicare calculate your income to determine whether you’ll pay higher premiums? Read on for an in-depth look at how your Medicare costs are adjusted based on income.

Medicare Part B Premium Rules

Let’s start with an overview of Medicare Part B monthly premiums. Some key things to know:

  • Most people turning 65 pay the standard premium amount each month for Part B.
  • Your Part B premium is determined based on your income from 2 years prior.
  • If your income exceeds certain thresholds, you’ll pay an IRMAA premium on top of the standard amount.
  • IRMAA premiums for higher earners can total over $500 per month.
  • Married couples face double the income thresholds for the standard premium versus individuals.

So while most seniors pay the same Part B premium cost, higher earners pay progressively more based on their income.

How Medicare Calculates Your Income

In determining whether you’ll pay higher Part B premiums, Medicare looks at your modified adjusted gross income (MAGI) from two years prior.

For example, your monthly premiums in 2023 will be based on your MAGI and tax filing status for 2021. Here is how your income is calculated:

  • Start with your adjusted gross income (AGI) from your 2021 IRS Form 1040 tax return
  • Add back any tax-exempt interest income you received
  • Include any non-taxable Social Security benefits
  • Add back certain deductions like student loan interest, self-employed health insurance premiums, and others

This formula gives you the total MAGI amount that Medicare uses to determine your income bracket and corresponding Part B premium.

Income Thresholds for Medicare Part B

Once your MAGI is calculated, Medicare compares it against set income thresholds to determine your Part B premium costs.

Here are the income brackets for 2023 Part B premiums:

Filing IndividuallyMarried Filing JointlyMonthly Premium
$97,000 or below$194,000 or below$164.90
$97,001 – $123,000$194,001 – $246,000$230.80
$123,001 – $153,000$246,001 – $306,000$329.70
$153,001 – $183,000$306,001 – $366,000$428.60
$183,001 – $499,999$366,001 – $749,999$527.50

Over $500,000 Over $750,000 $548.30

If your income falls into the higher brackets, you’ll pay the corresponding IRMAA premium in addition to the standard $164.90 premium cost.

For example, an individual with $180,000 in MAGI would pay the standard amount plus $363 extra per month for a total 2023 Part B premium of $527.50.

Medicare Part D Premiums Also Adjusted

In addition to potentially higher Part B premiums, higher earners also pay more for Medicare Part D prescription drug coverage.

If your income exceeds $97,000 as an individual or $194,000 as a couple, you’ll pay an extra monthly amount directly to Medicare for your Part D Plan. Here are the 2023 Part D IRMAA amounts:

$97,000 or below |$0 $97,001 – $123,000|$13.20 $123,001 – $153,000|$32.80 $153,001 – $183,000|$52.40 $183,001 – $499,999|$71.90 Over $500,000|$86.80

So higher earners pay more for both Medicare Part B and Part D coverage.

Avoiding Late Enrollment Penalties

In addition to income adjustments, it’s important to know Medicare’s enrollment timing rules to avoid penalties.

If you don’t sign up for Part B when first eligible at 65, you may face a late enrollment penalty that permanently increases your premium if you join later.

However, as long as you maintain health coverage such as through an employer plan, you can enroll in Part B during a Special Enrollment Period without penalty.

Understanding these rules is key to minimize Medicare costs.

Steps to Reduce Medicare Premium Expenses

If you fall into the higher income brackets, here are some potential steps to reduce your Medicare premium expenses:

  • Appeal your IRMAA premium if your income has dropped significantly since the tax return used to determine premiums.
  • Compare Medicare Advantage Plans premium annually and switch to options with lower costs.
  • Evaluate Part D prescription plans each year during open enrollment and change plans to reduce premiums.
  • Contribute pre-tax dollars to Health Savings Accounts and Flexible Spending Arrangements to decrease your MAGI.
  • Discuss lowering your future MAGI with a tax advisor to get into a lower premium bracket.
  • See if you qualify for assistance from a Medicare Savings Program through your state Medicaid office.

Carefully monitoring your MAGI and Medicare options can help minimize premium costs for higher earners.

The Bottom Line

In summary, Medicare determines your Part B and Part D premium costs based on your income from two years prior. Income over set thresholds results in higher earners paying an income-related monthly adjustment amount.

Checking your MAGI calculation and utilizing strategies to reduce premiums allows higher-income beneficiaries to manage Medicare expenses.
