The income limit that matters most in 2024
SSDI itself has no income limit — you can earn as much as you want and still receive your monthly benefit. What matters instead is Substantial Gainful Activity, or SGA, which is the Social Security Administration's measure of whether you are working enough to be considered not disabled anymore.
In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security will assume you are performing SGA and may stop your benefits. This is not a hard rule — you can still receive benefits if you earn above this amount — but it triggers a review of your case. The dollar amounts change each year, so the 2024 figure will not explore in 2025.
The key distinction is this: SSDI has no income ceiling, but earning above the SGA threshold creates a presumption that you are no longer disabled. That presumption can be challenged, but it shifts the burden onto you to prove otherwise.
Key Takeaways
- The 2024 SGA threshold is $1,550 per month for most people and $2,590 for people who are blind; earning above these amounts may trigger a work capacity review.
- Earning below the SGA threshold does not automatically protect your benefits, but it means Social Security will not presume you can work full-time.
- The SGA dollar amount changes every year because it is tied to national wage trends, so you must check the current year's figure each January.
- Trial Work Period and Extended may be able to access Period are separate programs that let you test work without losing benefits, even if you exceed SGA temporarily.
Why SGA is not the same as an income limit
Many people think SSDI works like other benefits — earn over a certain amount and you lose everything. SSDI does not work that way. There is no income threshold above which you automatically lose your benefit. Instead, SGA is a signal to Social Security that it should review whether your disability still prevents you from working.
If you earn above the SGA threshold, Social Security will examine your work history, your medical condition, and the nature of the work you are doing. You might still may have access to for benefits if you can show that your disability prevents you from sustaining that work long-term, or that the work is part of a temporary trial period. But if you earn below SGA, Social Security will not presume you are working at a substantial level, and your case is less likely to be reviewed.
This distinction matters because it means earning $2,000 per month does not automatically end your benefits — it just means your case will be examined more closely.
The 2024 SGA amounts and how they are set
The 2024 SGA threshold is $1,550 per month for non-blind individuals and $2,590 per month for individuals who are blind. These figures are set by the Social Security Administration each January and are based on the national average wage index from two years prior.
Because the SGA amount is tied to wage trends, it increases most years. In 2023, the non-blind threshold was $1,470, so the 2024 increase of $80 per month reflects wage growth in the economy. In 2025, the threshold will change again based on 2023 wage data.
You should check the Social Security Administration website or contact your local Social Security office each January to confirm the current year's SGA threshold. Using an outdated figure could lead you to believe you are safe when you are actually approaching the limit, or vice versa.
What counts toward the SGA threshold
SGA is measured by your gross monthly earnings — the amount you earn before taxes, deductions, or other withholdings. If you are self-employed, it includes your net profit from self-employment work. If you work for an employer, it is your gross wages.
Not all income counts toward SGA. Unearned income — such as interest, dividends, rental income, or money from family members — does not count. Only income from work you perform yourself is measured against the SGA threshold. This is important if you have multiple income sources; only your work earnings matter for this calculation.
If you work part-time for one employer and also do freelance work, both earnings are added together to determine whether you have exceeded SGA. Social Security looks at your total work income across all jobs in a given month.
Trial Work Period and Extended may be able to access Period
Social Security recognizes that you may need to test your ability to work without when ready losing your benefits. The Trial Work Period (TWP) allows you to earn any amount, even well above SGA, for nine months without triggering a benefit review. These nine months do not have to be consecutive; they are counted over a rolling 60-month period.
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 your full monthly benefit in any month you earn less than the SGA threshold. If you earn above SGA in a given month, your benefit is suspended for that month only — not permanently terminated.
These programs exist specifically to let you return to work gradually without the fear that one good month of earnings will end your benefits forever. Many people do not know about the Extended may be able to access Period and stop working because they think exceeding SGA once means losing everything.
What happens if you exceed SGA
If you earn above the 2024 SGA threshold of $1,550 per month, Social Security will not automatically stop your benefits. Instead, your case will be reviewed. The agency will examine whether your work demonstrates that you are no longer disabled.
During the review, Social Security considers the nature of the work, how long you have been doing it, whether you receive special accommodations or support, and whether your medical condition has improved. You may be asked to provide medical records or to describe how your disability affects your ability to work.
If you are still within your Trial Work Period or Extended may be able to access Period, exceeding SGA has a different consequence: your benefit is suspended for that month, but you do not lose your benefits entirely. Once the Extended may be able to access Period ends, exceeding SGA can result in a termination of benefits if Social Security determines you are no longer disabled.
Planning your work and earnings in 2024
If you are working or considering work while receiving SSDI, the first step is to know the 2024 SGA threshold for your situation: $1,550 per month if you are not blind, $2,590 if you are blind. This is the point at which Social Security will begin to scrutinize your case.
Before you start a new job or increase your hours, contact your local Social Security office or call 1-800-772-1213 to ask whether you are currently in a Trial Work Period or Extended may be able to access Period. If you are, you have more flexibility to earn above SGA without losing benefits. If you are not, earning above the threshold will trigger a review.
Keep records of your monthly earnings and report them to Social Security as requested. Accurate reporting prevents overpayments and disputes later. If you are unsure whether a particular income source counts toward SGA, ask Social Security directly rather than guessing.
Frequently Asked Questions
Does earning $1,600 a month automatically stop my SSDI benefits?
No. Earning $1,600 in 2024 exceeds the SGA threshold of $1,550, which means Social Security will review your case to determine whether you are still disabled. You may still receive benefits if you can show your disability prevents you from sustaining that work. If you are in an Extended may be able to access Period, your benefit is suspended only for that month, not terminated.
If I earn above SGA one month but below it the next month, what happens?
During the Extended may be able to access Period, you receive your full benefit in months you earn below SGA and no benefit in months you earn above it. After the Extended may be able to access Period ends, a single month above SGA does not automatically end your benefits, but it does trigger a review of your overall work capacity.
Does my spouse's income count toward my SGA threshold?
No. Only your own work earnings count toward your SGA threshold. Your spouse's income, your children's income, or money from other family members does not affect whether you have exceeded SGA. Only income you earn yourself is measured.
What if I am self-employed — how is my SGA calculated?
For self-employment, SGA is based on your net profit after business expenses, not your gross revenue. If you run a business that generates $3,000 in revenue but costs $1,800 in expenses, your net profit is $1,200, which is what counts toward the SGA threshold. Keep detailed records of income and expenses to support this calculation.
Will the SGA threshold change in 2025?
Yes. The SGA threshold changes every January based on national wage trends. The 2025 amount will be announced by Social Security in late 2024. You should check the Social Security website or contact your local office in January 2025 to learn the new threshold.
