What Income Is Used to Determine Medicare Premiums?

Medicare is a federal health insurance program that provides coverage for eligible individuals aged 65 and older, as well as certain younger individuals with disabilities. While most people are aware of the basic eligibility requirements and benefits of Medicare, many may not be familiar with how their income can affect their Medicare premiums.

In this article, we will explore the various types of income that are used to determine Medicare premiums and provide an extensive understanding of this important aspect of Medicare.

Understanding Medicare Premiums

Before delving into the details of income and its impact on Medicare premiums, it is essential to have a basic understanding of how Medicare premiums are calculated. Medicare consists of several different parts, including Part A (hospital insurance), Part B (medical insurance), Part C (Medicare Advantage), and Part D (prescription drug coverage). Each part of Medicare may have its own premium structure, and the income used to determine these premiums may differ depending on the specific part.

Medicare Part B, which covers medically necessary services like doctor visits and outpatient care, is the focus of our discussion on income and premiums. The standard Part B premium amount is set by the federal government each year. However, individuals with higher incomes may be subject to an Income-Related Monthly Adjustment Amount (IRMAA), which is an additional amount added to their Part B premium.

Types of Income Used to Determine Medicare Premiums

To determine if an individual is subject to IRMAA and the amount of the adjustment, the Social Security Administration (SSA) uses the modified adjusted gross income (MAGI) reported on an individual’s tax return from two years prior. The MAGI includes several types of income, and we will explore each of them in detail.

1. Adjusted Gross Income (AGI)

The first type of income used to determine Medicare premiums is the adjusted gross income (AGI). AGI is the total income an individual receives from all sources, minus certain deductions allowed by the Internal Revenue Service (IRS). It is an essential factor in calculating an individual’s tax liability and is reported on the IRS Form 1040.

2. Tax-Exempt Interest

Tax-exempt interest refers to the interest an individual receives from investments that are exempt from federal income tax. These investments may include municipal bonds issued by state or local governments. While tax-exempt interest is not included in an individual’s AGI, it is considered income for the purpose of determining Medicare premiums.

3. Taxable Social Security Benefits

Social Security benefits can be subject to federal income tax, depending on an individual’s overall income. If an individual’s combined income (AGI plus tax-exempt interest plus one-half of their Social Security benefits) exceeds a certain threshold, a portion of their Social Security benefits may become taxable. This taxable portion is also included in the calculation of Medicare premiums.

4. Capital Gains

Capital gains are profits earned from the sale of assets, such as stocks, bonds, or real estate. When an individual sells an asset for more than its original purchase price, they realize a capital gain. Like tax-exempt interest, capital gains are not included in an individual’s AGI but are considered income for the purpose of determining Medicare premiums.

5. Foreign Income

For individuals who earn income from foreign sources, such as foreign investments or employment abroad, that income is also included in the calculation of Medicare premiums. This income is reported on an individual’s tax return and is subject to the same rules and thresholds as other types of income.

Income-Related Monthly Adjustment Amount (IRMAA)

Once an individual’s MAGI is determined by considering the types of income mentioned above, the SSA uses a sliding scale to calculate the Income-Related Monthly Adjustment Amount (IRMAA). The IRMAA is added to the standard Part B premium and results in a higher premium for individuals with higher incomes.

The sliding scale for IRMAA has different income thresholds for individuals and married couples filing jointly. For example, in 2024, the income thresholds for individuals are:

• $103,000 or less for individuals: No adjustment
• $103,001 to $129,000 for individuals: $69.90 adjustment
• $129,001 to $161,000 for individuals: $174.70 adjustment
• $161,001 to $193,000 for individuals: $279.50 adjustment
• $193,001 to $500,000 for individuals: $384.30 adjustment
• $500,001 or more for individuals: $419.30 adjustment

The income thresholds for married couples filing jointly are higher, allowing for a larger income range before being subject to an adjustment. It is important to note that these income thresholds may change annually, so it is essential to check the most up-to-date information to determine if you are subject to an IRMAA.

Reporting Changes in Income

As the income used to determine Medicare premiums is based on an individual’s tax return from two years prior, it is possible for individuals to experience significant changes in income that may affect their premiums. If an individual’s income has decreased since the most recent tax return on record, they may request a reconsideration of their IRMAA. This process is known as a “life-changing event” and allows individuals to provide evidence of a significant income decrease, such as retirement or the cessation of work.

On the other hand, if an individual’s income has increased since the most recent tax return, they are required to pay the higher premium until the next tax return is filed and the SSA has the updated income information. It is crucial to report any changes in income promptly to avoid potential penalties or incorrect premium calculations.

Conclusion

Understanding the role of income in determining Medicare premiums is vital for individuals approaching or already enrolled in Medicare. The types of income used, such as adjusted gross income, tax-exempt interest, taxable Social Security benefits, capital gains, and foreign income, all play a role in determining an individual’s premium amount. The Income-Related Monthly Adjustment Amount (IRMAA) is added to the standard Part B premium for individuals with higher incomes, resulting in a higher monthly premium.

It is essential for individuals to stay informed about their income and report any changes promptly to ensure accurate premium calculations. By understanding the impact of income on Medicare premiums, individuals can better plan for their healthcare expenses and make informed decisions regarding their Medicare coverage.

Remember, Medicare premiums are just one aspect of the program, and it is advisable to consult with a qualified professional or visit the official Medicare website for comprehensive information on eligibility, coverage, and premiums.
