What income level determines how much you pay for Medicare? Many people don't realize Medicare uses your taxable income to calculate premiums. Here's how this income-related monthly adjustment amount (IRMAA) works and what income ranges will impact your Medicare premium costs.
Medicare Part B and Part D Base Premiums 2023
Before looking at income adjustments, it helps to understand the base Medicare premium amounts:
Part B Premium - The standard Part B premium for 2023 is $164.90/month. This applies to individuals with income of $97,000 or less.
Part D Premium - Varies by plan but averages around $32/month in 2023 for standard coverage. Higher earners pay more.
These are the baseline premium costs before any income-based adjustments. High earners will pay surcharges on top of these amounts.
What Triggers Higher Medicare Premiums
Medicare Part B and D premiums are higher if your income exceeds $97,000 as an individual tax filer or $194,000 for a married couple filing jointly. The extra premium amounts are called IRMAA (income-related monthly adjustment amount).
Income levels are based on your latest federal tax return from two years prior. So your 2023 premiums use your reported Modified Adjusted Gross Income (MAGI) on your 2021 IRS tax return.
MAGI includes adjusted gross income plus any tax-exempt interest income you received. Social Security benefits are not counted. The highest IRMAA bracket for 2023 is $750,000 individual / $1.5 million joint filers.
Impact on Part B and Part D Plan Premiums
Here are the income brackets and additional premium amounts added for 2023:

These affect both your Part B and Part D premiums. The income thresholds may be a bit higher than you expect. Married couples get some leeway owing to combined income.
How Medicare Calculates Your Income
Your MAGI and household size on your federal tax return are used to determine if you'll pay a higher Part B and D premium. Make sure your filed return accurately reflects your income.
If you filed married filing jointly, you get double the income allowance compared to an individual return before IRMAA surcharges kick in.
Notified Via Mail Each Year
You'll be notified by letter if you are subject to IRMAA based on your tax return. This notice is sent each fall in time for you to factor in the higher premium during Medicare open enrollment.
If your income has gone down more recently, you can file an appeal by submitting evidence to request reducing the premium.
Plan Smart Knowing Higher Income Means Higher Costs
Even at middle class retirement income levels, your Medicare costs increase compared to the base amounts. Make sure to factor this in as you budget healthcare expenses and weigh Medicare Plan options each year.
Understanding how Medicare premiums are calculated can help you project costs more accurately during retirement and reduce surprises at enrollment time.
