SSDI has a federal income limit, not a state one, so Illinois follows the same rules as every other state

Social Security Disability Insurance (SSDI) does not have an income limit that changes based on where you live. The Substantial Gainful Activity (SGA) limit is set by the federal government and applies to everyone receiving SSDI, whether you live in Illinois, California, or anywhere else. In 2024, that limit is $1,550 per month for non-blind individuals and $2,590 per month for blind individuals. If you earn more than these amounts, Social Security may consider you able to work and could reduce or stop your benefits.

Illinois does not add its own income limits on top of the federal ones. What matters is whether your earnings cross the SGA threshold that Social Security uses nationally. This is different from some other benefit programs—Supplemental Security Income (SSI), for example, does have state variations—but SSDI works the same way everywhere.

Key Takeaways

  • SSDI income limits are federal, not state-based, so Illinois residents follow the same SGA limits as everyone else receiving SSDI.
  • The 2024 SGA limit is $1,550 per month for non-blind beneficiaries and $2,590 per month for blind beneficiaries.
  • These dollar amounts change each year, usually in October or November, so you should check Social Security's website annually to see the current limit.
  • Earning above the SGA limit does not automatically end your benefits, but it signals to Social Security that you may be able to work and triggers a review of your case.

What counts as income for the SGA test

Social Security counts earned income—money you make from working—toward the SGA limit. This includes wages from a job, net profit from self-employment, and certain other forms of work-related pay. It does not include unearned income like Social Security benefits themselves, pensions, interest, dividends, or rental income.

The way Social Security measures your earnings matters. They look at your average monthly earnings over the period you worked. If you had a few high-earning months but then stopped working, Social Security will average those months to see if you crossed the SGA line. This is why someone who worked for three months at $2,000 per month and then stopped might still trigger a review, even though they are no longer earning anything.

If you are self-employed, Social Security counts your net profit after business expenses, not your gross revenue. You will need to show tax returns or business records to prove what you actually earned.

How the trial work period and extended may be able to access protect you

SSDI includes built-in protections that let you test your ability to work without when ready losing benefits. The trial work period allows you to earn any amount for nine months without affecting your SSDI payment. During these nine months, Social Security does not count your earnings against the SGA limit at all. You keep your full benefit check no matter how much you earn.

After your trial work period ends, you enter the extended may be able to access period, which lasts 36 months. During this time, you can still receive a benefit check in any month your earnings fall below the SGA limit. If you earn above the limit in a particular month, you do not get a check that month, but your benefits do not stop permanently. The moment your earnings drop back below SGA, your benefits resume.

These protections exist specifically so people can try working without the fear of losing their entire benefit structure. Illinois residents have access to the same trial work period and extended may be able to access as SSDI beneficiaries everywhere.

What happens if you earn above the SGA limit

Earning more than the SGA limit does not automatically end your SSDI. Instead, it tells Social Security that you may be able to work and triggers what is called a continuing disability review (CDR). Social Security will contact you and ask for information about your work, your medical condition, and whether your condition has improved.

During a CDR, Social Security looks at the whole picture: not just your earnings, but whether you can actually do the work you are doing given your disability. Someone earning $2,000 per month at a job they can only do because of accommodations, or because they work very few hours, might still be found disabled. Someone earning $1,400 per month at a job that requires full-time work and no accommodations might be found able to work. The SGA limit is a starting point, not the final answer.

If Social Security decides you are no longer disabled, your benefits will stop. You have the right to request reconsideration and, if denied, to appeal to an administrative law judge. During the appeal process, you can continue to receive benefits while your case is reviewed.

The difference between SSDI and SSI income limits in Illinois

If you receive Supplemental Security Income (SSI) instead of SSDI—or in addition to it—Illinois does have its own income limits that sit on top of the federal ones. SSI is a needs-based program, and Illinois sets resource limits and income thresholds that are sometimes stricter than the federal baseline. SSDI, by contrast, is based on your work history and has no state variation.

It is possible to receive both SSDI and SSI at the same time if your SSDI payment is very small. In that case, you would need to meet both the federal SGA limit and Illinois's SSI income rules. If you are unsure which program you receive or whether you may have access to for both, you can call Social Security at 1-800-772-1213 and ask them to review your account.

When the SGA limit changes and how to stay informed

The SGA limit increases most years because it is tied to the national average wage index. Social Security announces the new limit in October or November for the following year. In Illinois, this change affects all SSDI beneficiaries the same way it affects beneficiaries in every other state.

You can find the current and upcoming SGA limits on the Social Security Administration website at ssa.gov. If you work or are thinking about returning to work, it is worth checking this page once a year to know what threshold applies to you. You can also call your local Social Security office or the national number to ask what the current limit is.

Some people set up a work incentive plan with Social Security before they start working. This is called a Plan to Achieve Self-Support (PASS), and it lets you set aside income and resources for a specific work goal without it counting against your benefits. A PASS is complex and requires Social Security approval, but it can be valuable if you are planning to return to work gradually.

Frequently Asked Questions

Does Illinois have a lower income limit for SSDI than other states?

No. SSDI income limits are federal and the same everywhere. Illinois does not set its own SSDI income threshold. The SGA limit of $1,550 per month (for non-blind individuals in 2024) applies to you whether you live in Illinois or any other state.

What if I earn money but do not report it to Social Security?

Social Security can find out about unreported earnings through tax records, employer reports, and other sources. If you do not report earnings and Social Security discovers them later, you may have to repay benefits you received while you were over the SGA limit, plus interest. It is always better to report your work upfront.

Can I work part-time and still keep my SSDI in Illinois?

Yes, as long as your monthly earnings stay below the SGA limit during your extended may be able to access period, or if you are still within your nine-month trial work period. Many people work part-time and receive SSDI. The amount of hours you work does not matter—only how much you earn per month.

If I move to another state, does my SSDI income limit change?

No. SSDI income limits do not change when you move. The SGA threshold follows you because it is a federal rule, not a state rule. If you move from Illinois to another state, your income limit stays the same.

How do I know if I am in my trial work period or extended may be able to access period?

Social Security tracks this for you and should have sent you a notice explaining which period you are in when you started receiving SSDI. You can also call Social Security at 1-800-772-1213 and ask them directly. Knowing which period you are in is important because it changes how your earnings affect your benefits.
