SSDI counts as income for Affordable Care Act subsidies, but the calculation depends on your household size and other earnings

When you receive Social Security Disability Insurance (SSDI), the Social Security Administration counts it as income for purposes of the Affordable Care Act (ACA) subsidies—the tax credits that lower your monthly health insurance premiums. The amount of subsidy you receive shrinks as your total household income rises. SSDI is treated the same way as wages or other income sources: it goes into the pot that determines whether you fall below the income threshold for a subsidy, and if you do, how much that subsidy is worth.

The subsidy calculation is not automatic. You must report your SSDI income when you explore for coverage through Healthcare.gov or your state's health insurance marketplace. If you underreport or fail to report SSDI, you may receive a larger subsidy than you are may have access to to, and the IRS will ask you to repay the difference when you file taxes the following year. Conversely, if you overestimate your income, you may receive a smaller subsidy than you could have claimed.

Key Takeaways

  • SSDI income is counted dollar-for-dollar toward your household income for ACA subsidy purposes, just like wages or self-employment income.
  • Your subsidy amount depends on your total household income, household size, and the cost of the second-lowest-cost silver plan in your area—not on your individual SSDI amount.
  • You must report your SSDI income when you enroll in a marketplace plan; underreporting can result in repayment demands from the IRS at tax time.
  • If your SSDI income changes during the year, you can update your marketplace process and your subsidy may adjust when ready.
  • SSDI recipients may also be may be able to access for Medicaid, which has separate income rules and may offer coverage with no premium at all.

How SSDI income enters the subsidy calculation

The ACA subsidy is based on your modified adjusted gross income (MAGI), a figure that includes SSDI, wages, self-employment income, interest, dividends, and certain other sources. For SSDI recipients, MAGI is typically your SSDI amount plus any other income you or your spouse earn. If you are married and file taxes jointly, your spouse's income counts too, even if your spouse does not receive SSDI.

The marketplace compares your MAGI to the federal poverty line for your household size. The subsidy is available to people whose income falls between 100 percent and 400 percent of the federal poverty line (some states have expanded Medicaid to cover people below 138 percent). The higher your income, the larger the share of the premium you are expected to pay out of pocket. At 400 percent of poverty, the subsidy phases out entirely.

For example, in 2024, the federal poverty line for a single person is approximately $14,600 per year. Four hundred percent of that is about $58,400. If you receive $1,500 per month in SSDI ($18,000 per year) and have no other income, your MAGI is $18,000, which falls well below the 400 percent threshold. You would be in the range where subsidies are available. The exact subsidy amount depends on the cost of the second-lowest-cost silver plan in your county.

The role of the second-lowest-cost silver plan benchmark

The marketplace does not straightforward hand you a fixed dollar amount. Instead, it calculates your subsidy by comparing your income to a specific health plan: the second-lowest-cost silver plan available in your county. This plan's monthly premium is the benchmark. The government expects you to pay a percentage of your income toward that premium; the subsidy covers the rest.

The percentage you are expected to pay rises as your income rises. At 100 percent of poverty, you might be expected to pay 2 percent of your income toward the benchmark premium. At 300 percent of poverty, you might be expected to pay 9 percent. At 400 percent, you might be expected to pay 8.5 percent (the percentage can decrease at the highest income levels). If the benchmark premium is $300 per month and you are expected to pay 5 percent of your income, and your income is $24,000 per year ($2,000 per month), you would pay $100 per month and the subsidy would cover $200.

This means two SSDI recipients with the same monthly benefit can receive different subsidy amounts if they live in different counties, because the benchmark plan costs different amounts in different places. A recipient in a rural county might see a lower benchmark premium than one in an urban area.

Reporting SSDI income on your marketplace process

When you create an account on Healthcare.gov or your state marketplace, you will be asked to report your household income. You must include your SSDI income. The marketplace will ask you to estimate your income for the current year. If you have been receiving SSDI for a while and expect the amount to stay the same, you can use your current monthly benefit multiplied by 12.

You do not need to submit a Social Security statement or proof of SSDI at the time of enrollment, though the marketplace may verify your income later by checking records with the Social Security Administration. If your reported income does not match SSA's records, the marketplace will contact you to correct it.

If you are unsure of your exact SSDI amount, you can log into your my Social Security account at ssa.gov to view your current benefit. You can also call Social Security at 1-800-772-1213 to ask for your monthly benefit amount. Using an accurate figure is important because underreporting will lead to a reconciliation bill from the IRS the following April.

What happens if your SSDI changes during the year

SSDI amounts can change if you reach full retirement age (your benefit may increase), if you have a cost-of-living adjustment (COLA), or if your benefit is suspended or terminated due to work earnings or other factors. If your SSDI income changes, you can report the change to the marketplace and your subsidy will be recalculated.

The marketplace allows you to update your process at any time, not just during the annual open enrollment period. If your SSDI increases, your subsidy will decrease (because your income is higher). If your SSDI decreases, your subsidy will increase. The change takes effect the month after you report it, so it is worth updating promptly if a significant change occurs.

If you fail to report a change and it is discovered at tax time, you may owe money back to the government. Conversely, if you reported a decrease that did not actually happen, you may have received a larger subsidy than you were may have access to to and will face a repayment demand.

SSDI, Medicaid, and the interaction with marketplace coverage

Many SSDI recipients are also Medicaid-may be able to access, depending on their state and income. Medicaid has its own income rules, separate from the ACA marketplace. In states that have not expanded Medicaid, SSDI recipients may be limited to Medicaid only if they are also over 65, blind, or have a child under 19. In states that have expanded Medicaid, the income limit is typically 138 percent of the federal poverty line.

If you are Medicaid-may be able to access, you do not need to buy a marketplace plan. Medicaid is free and typically has no deductible. However, if your income is above your state's Medicaid limit but below 400 percent of poverty, you can enroll in a marketplace plan and receive a subsidy. Some people are may be able to access for both but choose marketplace coverage because it offers more choice of providers or because they prefer not to be on Medicaid.

If you are enrolled in both Medicaid and a marketplace plan, your SSDI income counts toward both programs' income calculations. You cannot use the same income to reduce your marketplace premium and also claim Medicaid benefits based on a lower income—each program calculates your income independently.

Tax reconciliation and repayment of excess subsidies

At the end of the year, you will file a tax return (if you have any tax filing requirement) and reconcile the subsidies you received with the subsidies you were actually may have access to to. This reconciliation happens on Form 8962, which you attach to your tax return. If you received more subsidy than your actual income may have access to you to, you will owe the difference back to the IRS. If you received less, you will receive a refund.

The repayment can be substantial if you significantly underreported your income. For example, if you reported $18,000 in SSDI income but actually received $24,000, and that difference pushed you above the subsidy threshold, you could owe back several months of subsidies. The IRS does not forgive these debts easily, and they can be offset against future tax refunds.

To avoid reconciliation problems, report your income as accurately as possible when you enroll and update your process if your income changes. The marketplace has a tolerance for small differences (typically $200 or less), but large discrepancies will trigger a repayment bill.

Frequently Asked Questions

If I receive SSDI, am I automatically ineligible for a marketplace subsidy?

No. SSDI is counted as income, but it does not disqualify you. If your SSDI income (plus any other household income) falls below 400 percent of the federal poverty line, you can receive a subsidy. Most SSDI recipients fall well below this threshold and are may have access to to substantial subsidies.

Do I have to report my SSDI income every year when I renew my marketplace plan?

Yes. The marketplace requires you to report your current income each year during open enrollment. If your SSDI amount has not changed, you can report the same figure. If it has changed due to a COLA or other adjustment, report the new amount.

What if I work part-time and also receive SSDI—how does that income count?

Both your wages and your SSDI are added together to calculate your total household income for subsidy purposes. If you earn $12,000 per year and receive $18,000 in SSDI, your MAGI is $30,000. Both sources count equally toward the income threshold.

Can I get a larger subsidy by not reporting my SSDI?

You could, but the IRS will catch it. The marketplace verifies SSDI income with Social Security, and if your reported income is lower than your actual SSDI, you will owe back the excess subsidy at tax time, plus potential penalties.

If I am on Medicaid, do I still need to buy a marketplace plan?

No. If you are Medicaid-may be able to access, you have free coverage and do not need a marketplace plan. However, if your income is above your state's Medicaid limit, you can enroll in the marketplace and your SSDI will count toward your subsidy calculation there.
