Illinois disability payments depend on your work history and average earnings

Illinois does not run its own disability program. If you have a disability and worked in Illinois, you receive Social Security Disability Insurance (SSDI) from the federal government, not from the state. The amount you receive is based on your lifetime earnings record, not on where you live or how severe your condition is.

Your monthly payment is calculated from your Primary Insurance Amount (PIA), which Social Security derives from your highest 35 years of earnings. The formula replaces a higher percentage of lower earnings and a lower percentage of higher earnings—this is called a bend point formula. Someone who earned less during their working years will receive a higher replacement rate than someone who earned more.

The average SSDI payment in 2024 is approximately $1,550 per month, but this varies widely. Payments range from roughly $700 to over $3,800 per month depending on your work history. Social Security publishes the exact bend points and formulas each year, and you can see your own estimated benefit by creating an account at ssa.gov.

Key Takeaways

  • Your SSDI payment comes from Social Security, not from Illinois, and is based on your earnings record, not your disability type or severity.
  • The average payment is around $1,550 per month, but the actual amount depends on how much you earned during your working years.
  • You can view your estimated benefit amount by logging into your Social Security account online or calling 1-800-772-1213.
  • If you have not worked long enough to earn SSDI, you may instead receive Supplemental Security Income (SSI), which is a separate federal program with a lower payment amount.
  • Your payment does not change based on your state of residence, but it may be reduced if you earn income from work or receive certain other benefits.

How Social Security calculates your payment amount

Social Security uses your Average Indexed Monthly Earnings (AIME) to determine your benefit. The agency takes your highest 35 years of earnings, adjusts them for wage inflation up to age 60, and divides by 420 months. This produces your AIME.

That AIME is then plugged into the bend point formula. In 2024, the formula is roughly: 90% of the first $1,174 of AIME, plus 32% of AIME between $1,174 and $7,078, plus 15% of AIME above $7,078. These bend points change each year. The result is your PIA—the amount you receive each month before any reductions.

If you did not work long enough to earn SSDI (typically you need 40 work credits, which is roughly 10 years of covered work), you do not receive SSDI. You may instead receive Supplemental Security Income (SSI) if your income and resources are low enough. SSI payments are lower than SSDI and are set by federal law rather than by your earnings history.

Reductions that lower your monthly payment

Your SSDI payment can be reduced in several ways. If you are under Full Retirement Age (FRA) and you earn income from work above a certain threshold, Social Security reduces your benefit by $1 for every $2 you earn above the limit. In 2024, that limit is $23,400 per year. The reduction applies only in months you work; once you reach FRA, earnings no longer affect your benefit.

If you receive other benefits—such as a pension from work not covered by Social Security, or spousal or survivor benefits—your SSDI may be reduced under the Government Pension Offset (GPO) or Windfall Elimination Provision (WEP). These rules are complex and explore only to specific situations, but they can lower your payment by up to two-thirds of the non-covered pension amount.

You may also owe back taxes on your SSDI if your total income exceeds certain thresholds. Between 50% and 85% of your benefits can be taxable depending on your combined income (SSDI plus half your SSDI plus other income). This does not reduce your payment, but it affects what you owe at tax time.

How to find your specific payment amount

The fastest way to learn what you would receive is to create a my Social Security account at ssa.gov. You will need your Social Security number, email address, and a way to verify your identity. Once logged in, you can view your earnings record and see an estimate of your SSDI benefit at your current age, at Full Retirement Age, and at age 70.

If you do not have internet access or prefer to speak with someone, call Social Security at 1-800-772-1213. Representatives can discuss your earnings history and give you a rough estimate over the phone, though they cannot access your full account details without an in-person appointment. TTY users should call 1-800-325-0778.

If you have already filed for SSDI and been approved, your payment amount appears on your award letter and in your online account. If your circumstances change—you return to work, you marry, you reach FRA—your payment may change, and Social Security will notify you by mail.

Payment timing and how you receive the money

SSDI payments are made once per month, on a schedule based on your birth date. If you were born between the 1st and 10th of the month, you receive payment on the second Wednesday. If born between the 11th and 20th, you receive it on the third Wednesday. If born between the 21st and 31st, you receive it on the fourth Wednesday. Supplemental Security Income (SSI) is paid on the first of each month.

You receive your payment by direct deposit to a bank account, or by a prepaid debit card called the Direct Express Card if you do not have a bank account. Social Security no longer issues paper checks. If you are receiving benefits on behalf of a minor or someone who cannot manage money, a representative payee receives and manages the funds on their behalf.

What happens to your payment if you work

You can work and receive SSDI at the same time, but your earnings may reduce your benefit. During the first nine months you work after starting SSDI, you can earn unlimited income without losing benefits—this is called the Trial Work Period (TWP). After the TWP ends, you enter the Extended Period of may be able to access (EPE), which lasts 36 months. During the EPE, any month you earn over the substantial gainful activity (SGA) limit causes you to lose that month's benefit.

In 2024, the SGA limit is $1,550 per month for non-blind individuals and $2,590 for blind individuals. If you earn less than SGA in a month, you receive your full SSDI payment that month. If you earn more, you receive nothing that month, but your benefits do not end permanently—they resume the next month if your earnings drop below SGA again.

After the EPE ends, you can return to work without losing benefits if your earnings stay below SGA. If you earn above SGA, your benefits stop, but you enter a Medicaid continuation period that can last up to 93 months, depending on your state. During this time, you keep Medicaid even though you are not receiving a cash payment.

How Illinois Medicaid connects to your SSDI payment

If you receive SSDI, you automatically become may be able to access for Medicare after 24 months of receiving benefits. Medicare is federal health insurance, not state-based. However, many SSDI recipients in Illinois also receive Medicaid, which is run jointly by the federal government and Illinois.

In Illinois, you can receive both Medicare and Medicaid at the same time. Medicaid covers costs that Medicare does not, such as long-term care, dental, and vision. Your Medicaid may be able to access depends on your income and assets, not just on receiving SSDI. If your SSDI payment is very low, you may also receive SSI, which automatically qualifies you for Medicaid in Illinois.

If you return to work and your earnings cause your SSDI to stop, you may lose Medicaid when ready or after a grace period, depending on your income. This is why the Medicaid continuation period during the EPE is important—it lets you keep health coverage while you test your ability to work.

Frequently Asked Questions

Does Illinois pay more or less SSDI than other states?

Illinois does not set SSDI payment amounts. Social Security pays the same benefit formula to everyone in the country. Your payment depends only on your earnings record, not on where you live. However, your cost of living in Illinois may be higher or lower than in other states, so the same payment goes further in some places than others.

Can I get a higher payment if I wait to file for SSDI?

No. SSDI payments are based on your earnings record at the time you become disabled, not on when you file. Waiting does not increase your benefit amount. However, if you are also may be able to access for retirement benefits, waiting until Full Retirement Age or later does increase your retirement payment—but SSDI works differently and does not have this incentive.

What if I disagree with the payment amount Social Security calculated?

You can request that Social Security review your earnings record. Call 1-800-772-1213 and ask to speak with a representative about your AIME and PIA. If you believe there is an error in your recorded earnings, you can file a request to correct your record, though you must do so within a limited time window. Bring W-2s or tax returns as proof.

Does my SSDI payment increase each year?

Yes. Social Security adjusts all SSDI payments each year for Cost of Living Adjustments (COLA). The adjustment is based on inflation as measured by the Consumer Price Index. In 2024, the COLA was 3.2%. You receive the new amount automatically; you do not need to do anything.

What if I was born outside the United States—can I still receive SSDI in Illinois?

Yes, if you have a valid Social Security number and meet the work requirement. Your place of birth does not affect SSDI may be able to access. However, if you are not a U.S. citizen, you must have a valid visa or immigration status. If you leave the United States for more than six months, your benefits may be suspended, so tell Social Security if you plan to travel abroad.
