Understanding Medicare Subsidy Income Rules and Income Thresholds

Medicare subsidies, formally called Extra Help or Low-Income Subsidy (LIS) programs, reduce the cost of prescription drug coverage for people who meet certain income requirements. The income thresholds that determine whether someone may be able to receive help change each year. In 2024, the income limits were set at 150% of the federal poverty level for the contiguous United States. For a single person, this meant an annual income of approximately $1,968 per month. For a married couple, the threshold was around $2,643 per month combined.

These numbers shift annually because the federal government adjusts poverty guidelines each year. The income limits in 2025 increased slightly, reflecting changes in the cost of living. Understanding what counts as "income" is critical, because not all money you receive counts toward these limits. For example, Supplemental Security Income (SSI) does not count as income when determining Extra Help eligibility, even though it counts as income for many other government programs. Similarly, certain types of unearned income and home equity are treated differently than wages.

The way income is calculated varies depending on the type of income. Earned income includes wages, salaries, and net self-employment income. Unearned income includes Social Security benefits (though not SSI), pensions, interest, dividends, and rental income. Some people receive a combination of both. A person who works part-time and also receives Social Security would need to count both toward the income limit. The Social Security Administration and Centers for Medicare and Medicaid Services provide updated income tables on their official websites each year.

One important detail: some states have different rules than federal guidelines. Maine, Massachusetts, and Vermont have their own Extra Help programs with higher income limits. In 2024, Maine allowed income up to 225% of the federal poverty level, which was considerably higher than the federal standard. If you live in one of these states, you may have additional options even if your income exceeds the federal threshold.

Practical takeaway: Write down your current monthly income from all sources (wages, Social Security, pensions, interest, rental income, etc.). Compare this number to your state's current income threshold, which you can find on the official Medicare website or your state's health department site. Remember that these thresholds change yearly, so last year's limits don't apply.

What Types of Income Count and What Doesn't

The income calculation for Medicare subsidies can be confusing because the rules treat different money sources differently. Social Security retirement benefits count toward the income limit, but Supplemental Security Income (SSI) payments do not. This distinction matters significantly for people receiving both types of payments. If you receive $900 per month in Social Security and $300 per month in SSI, only the $900 counts. This rule makes SSI recipients in particular better positioned to receive Extra Help.

Earned income—money you make from working—counts at full value. If you earn $2,000 per month from a job, that $2,000 counts entirely toward the income limit. However, if you're self-employed, only your net income (after business expenses) counts. Someone running a small business who earns $3,000 but has $1,200 in business expenses would count only $1,800 as income for subsidy purposes.

Unearned income sources have specific rules. Interest from savings accounts counts, as do dividends from stocks and bonds. Rental income counts, but you can deduct certain housing expenses related to the rental property. Pension payments, annuities, and distributions from retirement accounts all count. However, the return of your own principal or capital (not earnings on investments) typically does not count.

Some income sources are excluded entirely. Veterans' benefits, workers' compensation, and certain disability payments have different treatment depending on the specific program. Food assistance (SNAP), housing vouchers, and utility assistance do not count as income. Gifts and inheritances do not count, though earnings on inherited money would count once received. If you receive a lump sum payment—such as a settlement or bonus—it may be treated as income only in the month received, depending on how the program categorizes it.

Spousal income matters when determining household income. If you're married, your spouse's income counts toward your household total, even if it's kept separate or in a different account. This applies to legally married couples living together. The rules are different for unmarried partners or adult children living in the household—their income typically does not count.

Practical takeaway: Create a list of every income source you or your spouse receives: employment, Social Security, pensions, interest, rental income, and anything else. Note which items count and which don't based on the categories above. Many people overlook smaller income sources like interest or investment income, which can affect eligibility.

How Your Resources and Assets Affect Subsidy Determinations

While income is the primary factor in Extra Help decisions, some programs also examine resources or assets. The federal Extra Help program has resource limits, though these are relatively high. In 2024, the resource limit for a single person was $8,100, and for married couples it was $12,150. These limits increased in 2025 to approximately $8,400 and $12,600 respectively. Resources include savings accounts, checking accounts, stocks, bonds, and retirement accounts. However, many assets are excluded from this calculation.

Your primary residence does not count as a resource, no matter its value. This means a person living in a paid-off house worth $500,000 could still meet the resource limit for Extra Help. Similarly, one vehicle does not count toward the resource limit. Some personal possessions and household items are also excluded. However, a vacation home, rental property, or investment property would count as a resource.

Retirement accounts have complex rules. A traditional IRA or 401(k) that you haven't yet withdrawn from typically does not count as a resource for Extra Help purposes. However, once you begin taking distributions from a retirement account, the money you've withdrawn counts as a resource. Someone with $300,000 in an IRA who hasn't taken distributions yet would not count this toward the resource limit, but that same person taking $2,000 per month from the IRA would have $24,000 per year added to their countable resources.

Life insurance policies generally do not count as resources. However, life insurance with a cash surrender value—where you can borrow against it or cash it in—might be treated differently depending on the specific program and how it's structured. Burial accounts set aside for funeral expenses are excluded up to a certain amount. Vehicles beyond the first one do count as resources at current market value.

Some state programs have different or more lenient resource limits than the federal program. If you live in one of the states with its own subsidy program, the resource rules may be more favorable. It's worth investigating your specific state's rules if you're near the federal resource limit.

Practical takeaway: List your countable resources: savings, checking accounts, investments, and retirement account distributions you've already taken. Don't include your home, one vehicle, or retirement accounts you haven't touched yet. Add these up and compare to your state's resource limit. If you're close, consider whether you've missed any excluded items.

Income Reporting Requirements and How Changes Affect Your Coverage

Once someone receives Extra Help, keeping the Social Security Administration informed about income changes is essential. The rules require reporting significant changes in income or resources. Many people don't realize that changes must be reported, and this causes problems when their circumstances improve or worsen. If your income increases enough to exceed the limit, continuing to receive Extra Help without reporting the change can result in overpayments that may need to be repaid.

The definition of a "significant change" varies by program. Generally, increases in monthly income of $10 or more, decreases of $20 or more, or changes to living situation must be reported. Some changes don't need to be reported immediately but should be reported during the annual renewal process. For example, if you gain a small part-time job that adds $8 per month to your income, this might not trigger an immediate reporting requirement, but it should be included when your subsidy is reviewed annually.

Income changes can happen unexpectedly. A person receiving Social Security might get a cost-of-living adjustment (COLA) that increases their monthly payment. Someone with part-time work might see their hours reduced or increased. A spouse might start or stop working. In any of these cases, reporting the
