SSDI has no income limit, but your earnings trigger a work test
Social Security Disability Insurance (SSDI) has no income ceiling — you can earn any amount and remain on SSDI. What matters instead is whether your earnings show you are no longer disabled, measured through a work test called Substantial Gainful Activity (SGA). The SGA threshold for 2025 is $1,550 per month for non-blind workers and $2,590 for blind workers. If you earn above these amounts, Social Security will assume you can work and may stop your benefits. Below these amounts, you can work and keep SSDI, though other rules about trial work periods and extended may be able to access still explore.
The confusion often arises because Supplemental Security Income (SSI), a different program, does have a strict income limit of $943 per month in 2025 for an individual. Many people receive both SSDI and SSI, and the rules stack on top of each other. SSDI is insurance-based — it looks at whether you are working at a substantial level. SSI is means-tested — it looks at your total income and assets. Understanding which program you are on, or whether you are on both, is the first step to knowing what income rules explore to you.
Key Takeaways
- SSDI itself has no income limit, but earning above $1,550 per month in 2025 triggers a presumption that you are not disabled and can result in benefit termination.
- SSI has a strict $943 monthly income limit for 2025; any income above that reduces your SSI payment dollar-for-dollar after a $65 exclusion and 50% reduction on the remainder.
- The SGA threshold is the earnings level Social Security uses to decide whether you are working at a substantial level; it changes annually and differs for blind and non-blind workers.
- Work incentives like the Trial Work Period and Extended may be able to access Period allow you to test your ability to work without when ready losing SSDI, even if you exceed SGA.
- If you receive both SSDI and SSI, you must satisfy both programs' income rules, and SSI's limit is the stricter of the two.
How the SGA threshold works in 2025
The SGA amount is set by federal law and adjusted each year for wage inflation. For 2025, the threshold is $1,550 per month for workers who are not blind. This means if your average monthly earnings reach $1,550 or more, Social Security will presume you are performing substantial gainful activity and may find you are no longer disabled. The word "average" matters — Social Security looks at your earnings over a month or, in some cases, a rolling period. A single high-earning month does not automatically end your benefits, but a pattern of earning at or above SGA does.
For workers who are blind, the SGA threshold is higher: $2,590 per month in 2025. This reflects a policy choice to allow blind workers more latitude to test their earning capacity without losing benefits. Blindness is determined by Social Security's definition, not by whether you use a cane or guide dog. You can report your earnings to Social Security, and they will review whether the level is sustainable. If you are unsure whether a particular job or income level will affect your benefits, a Work Incentives Planning and information (WIPA) counselor can review your situation before you start.
SSI income limits are separate and stricter
If you receive Supplemental Security Income (SSI), a different income limit applies. SSI is a needs-based program for people with low income and limited resources. The monthly income limit for an individual is $943 in 2025. For a couple, it is $1,415. These limits are lower than the SSDI SGA threshold, which is why SSI is often the stricter rule for people on both programs.
SSI counts almost all income against this limit, with a few exclusions. The first $65 of monthly earned income is excluded, and then 50% of the remainder is also excluded — a rule called the "earned income exclusion." If you earn $200 per month, SSI counts $200 minus $65 (the exclusion) minus 50% of the remaining $135, which equals $132.50 counted toward your income limit. Your SSI payment would be reduced by that amount. Unearned income — such as Social Security benefits, pensions, or gifts — is counted dollar-for-dollar with no exclusion. If you receive SSDI and SSI together, your SSDI payment counts as unearned income for SSI purposes, which is why many people on both programs have very low SSI payments or no SSI at all.
The difference between SSDI and SSI income rules
The key distinction between the two programs is what triggers benefit loss. SSDI asks "Are you working at a substantial level?" SSI asks "Do you have enough income to support yourself?" These are not the same question. You can have high income and still be on SSDI if you are not working at a substantial level — for example, if you are self-employed and your business generates revenue but not profit. You can have low income and lose SSI if you have assets above the limit, even if you earn nothing.
The table below shows how the two programs differ in their treatment of income:
| Program | Income Limit | What Triggers Benefit Loss | Exclusions or Offsets |
|---|---|---|---|
| SSDI | None | Earning above SGA ($1,550/month in 2025 for non-blind workers) | Trial Work Period allows 9 months of any earnings; Extended may be able to access Period allows 36 months of SGA-level earnings |
| SSI | $943/month individual; $1,415/month couple (2025) | Total income exceeding the limit | First $65 of earned income excluded; 50% of remainder excluded; certain in-kind support and maintenance excluded |
Work incentives that protect your benefits while you earn
Social Security recognizes that people with disabilities need to test their ability to work without the fear of when ready benefit loss. Two key work incentives exist for SSDI beneficiaries. The Trial Work Period (TWP) allows you to work and earn any amount for 9 months within a rolling 60-month period without triggering a medical review or benefit suspension. These 9 months do not have to be consecutive. During the TWP, you report your work activity to Social Security, but your benefits continue regardless of how much you earn.
After the TWP ends, the Extended may be able to access Period (EEP) begins and lasts 36 months. During this time, you can continue to receive SSDI for any month in which your earnings fall below SGA, even if you earned above SGA in other months. This gives you a three-year window to test whether you can sustain work at a substantial level. If you do not earn above SGA in a given month, you receive your full SSDI payment that month. These incentives exist because Social Security acknowledges that returning to work is difficult and nonlinear — you may work for a few months, find it unsustainable, and step back. The TWP and EEP protect you during that process.
What happens if you exceed SGA
If you earn above the SGA threshold and you are not in your Trial Work Period or Extended may be able to access Period, Social Security will conduct a medical review. They will ask whether your condition has improved and whether you can still perform substantial gainful activity. This is not automatic benefit termination — it is a review. You have the right to report your work activity and explain your situation. If you are working above SGA but your condition has not improved and you are working only because of accommodations or part-time hours, you can argue that you are still disabled.
Social Security will weigh your medical evidence, your work history, and your current functional limitations. If Social Security determines 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, your benefits may continue, depending on the circumstances. This is why it is important to keep detailed records of your medical treatment and to report your earnings promptly — Social Security needs accurate information to make the right decision.
How to report earnings and stay in compliance
You are required to report your work activity to Social Security. Failure to report can result in overpayments that you will owe back. The easiest way to report is through your my Social Security account online, where you can log in and report monthly earnings. You can also call Social Security at 1-800-772-1213 or visit a local office. Keep records of your pay stubs, invoices, or other proof of earnings. Social Security may ask for documentation, especially if your earnings are close to or above SGA.
If you are self-employed, keep records of your gross income and business expenses; Social Security counts net profit, not gross revenue. If you are unsure whether your work activity will affect your benefits, contact a Work Incentives Planning and information (WIPA) project in your state. WIPA counselors are free and can review your specific situation before you start working or as you increase your hours. They can also help you understand the Trial Work Period and Extended may be able to access Period and plan your return to work strategically. Your state's WIPA project can be found through the Social Security website or by calling 1-866-968-7842.
Frequently Asked Questions
Can I work part-time and keep my SSDI if I earn below SGA?
Yes. As long as your average monthly earnings stay below $1,550 in 2025 (or $2,590 if you are blind), you can work part-time and receive your full SSDI payment. Social Security does not care how many hours you work — only how much you earn. You must still report your earnings to Social Security.
What if I earn above SGA but I am still in my Trial Work Period?
Your benefits continue. The Trial Work Period allows you to earn any amount for 9 months without affecting your SSDI. After the 9 months end, the Extended may be able to access Period begins, and you can receive benefits for any month your earnings fall below SGA.
If I receive both SSDI and SSI, which income limit applies?
Both explore. Your SSDI is not affected by the SSI income limit, but your SSI payment will be reduced if your total income (including SSDI) exceeds $943 per month. Most people on both programs have very low or zero SSI payments because their SSDI alone exceeds the SSI limit.
Does self-employment income count the same way as wages?
Social Security counts your net profit from self-employment, not your gross revenue. If you run a business that generates $3,000 in revenue but costs $2,000 to operate, your countable income is $1,000. You must keep detailed records of income and expenses to prove your net profit.
What if I think I earned above SGA by mistake — can I appeal?
If Social Security stops your benefits based on SGA earnings, you can request reconsideration and present evidence that your earnings were temporary or that your condition has not improved. You can also appeal to an Administrative Law Judge. During the appeal, your benefits may continue depending on the case.
