SSDI has no income limit, but your work earnings can reduce or stop your benefits
SSDI (Social Security Disability Insurance) does not have an income limit based on how much money you receive from other sources—you can have savings, investments, rental income, or a pension without affecting your benefits. What matters is how much you earn from work. If you work and earn above a certain threshold called Substantial Gainful Activity (SGA), Social Security may determine you are no longer disabled and stop your benefits.
The SGA threshold changes each year. For 2024, it is $1,550 per month for most people receiving SSDI, and $2,590 per month for people who are blind. These amounts are the official limits Social Security uses to decide whether your work earnings show you can do substantial work. If you earn less than these amounts, your benefits continue regardless of how much you work.
The key distinction is that SSDI looks at earned income (money from work) differently than unearned income (money from savings, investments, or other sources). Unearned income does not affect SSDI at all. Earned income is what triggers the SGA rule.
Key Takeaways
- You can have unlimited savings, investments, rental income, or pensions without losing SSDI benefits—only work earnings matter.
- If you earn more than $1,550 per month (or $2,590 if blind) in 2024, Social Security will review whether you can still work and may stop your benefits.
- The SGA threshold increases each year, so the amount that triggers a review will be higher in 2025 and beyond.
- Social Security offers work incentives like the Trial Work Period that let you test working without when ready losing benefits.
- You must report your work earnings to Social Security—they do not automatically know what you earn.
How Social Security counts your work earnings
Social Security counts gross earnings from self-employment or wages—the money before taxes are taken out. If you are self-employed, they count your net profit (income minus business expenses). They do not count the taxes you pay, transportation costs, or medical expenses related to your work.
The way Social Security measures your earnings depends on how you are paid. If you receive a salary or hourly wages, they count what your employer pays you. If you are self-employed, they count your net profit for the month. If you receive irregular payments—such as a bonus, commission, or seasonal work—they average those earnings over the months you receive them, which can push you above the SGA threshold even in months when you earn less.
Social Security also looks at your work history. If you have worked in the past but are currently not working, that past work does not count toward SGA. Only current work earnings matter. If you stop working, your benefits do not automatically restart—you must contact Social Security to report the change.
What happens if you earn above the SGA threshold
If you earn more than the SGA amount in a single month, it does not automatically end your benefits that month. Instead, Social Security will review your case to determine whether your earnings show you are able to do substantial work. This review can take several months. During that time, you continue to receive benefits while they investigate.
Social Security looks at more than just the dollar amount. They consider whether the work you are doing is the kind of work a person without a disability could do, whether you are working full-time or part-time, and whether your earnings are temporary or ongoing. For example, if you earn $2,000 one month from a temporary project but normally earn $800 per month, they may not count that single high month as proof you can work consistently.
If Social Security decides your earnings show you can do substantial work, they will send you a written notice explaining their decision and telling you when your benefits will end. You have the right to request reconsideration or a hearing before an administrative law judge if you disagree with their decision.
The Trial Work Period and Extended may be able to access
Social Security offers a Trial Work Period (TWP) that protects you while you test working. During the TWP, you can earn any amount and keep your full SSDI benefits for up to nine months (not necessarily consecutive). The months do not have to be in a row—you can use them spread across a longer period. This is designed to let you see whether you can sustain work without the when ready risk of losing benefits.
After your nine Trial Work Period months end, you enter the Extended may be able to access Period, which lasts 36 months. During this time, if you earn above the SGA threshold in any month, you lose benefits for that month only—not permanently. Once your earnings drop below SGA, your benefits restart the following month. This gives you a safety net if your work becomes inconsistent or if you need to reduce your hours.
After the Extended may be able to access Period ends, the regular SGA rule applies: if you earn above the threshold, your benefits stop and Social Security reviews your case. You must report your work to Social Security to use these protections—they do not happen automatically.
Reporting your work earnings to Social Security
You are required to report any work you do to Social Security, even if you earn below the SGA threshold. You can report your work by phone, mail, or online through your my Social Security account. Social Security recommends reporting within 30 days of starting work or when your earnings change significantly.
When you report, tell Social Security how much you earn per month, how many hours you work, and whether your job is temporary or ongoing. If you are self-employed, report your expected monthly net profit. Keep records of your pay stubs or business income so you can verify what you report if Social Security asks.
If you do not report your work and Social Security discovers you earned above SGA, they may overpay you (send you benefits you were not may have access to to). You would then have to repay that money. Reporting protects you because it creates an official record of when you started working and how much you earned.
Other income that does not affect SSDI
SSDI is not a means-tested program, which means your other income sources do not reduce your benefits. You can receive money from savings, investments, rental property, a pension, unemployment benefits, workers' compensation, or family support without any effect on your SSDI check. This is different from SSI (Supplemental Security Income), which does count unearned income and has strict resource limits.
If you inherit money, receive a settlement, or get a large gift, none of that changes your SSDI benefits. You can own a home, a car, or other property without limits. The only thing that matters for SSDI is whether your work earnings show you are able to do substantial work.
Some people confuse SSDI with SSI because both are Social Security programs. SSDI is based on your work history and disability—income does not matter. SSI is based on financial need—income and resources do matter and can disqualify you. If you receive SSDI, you do not need to worry about how much money you have in the bank.
SGA thresholds by year
The SGA threshold increases each year because it is tied to the national average wage index. Social Security announces the new amount in October or November for the following year. Below is how the threshold has changed in recent years for non-blind individuals:
| Year | Monthly SGA Threshold |
|---|---|
| 2022 | $1,350 |
| 2023 | $1,470 |
| 2024 | $1,550 |
For people who are blind, the threshold is higher. In 2024, it is $2,590 per month. These amounts explore to work you do after you start receiving SSDI. If you worked before you applied for SSDI, that past work does not count toward these limits.
Frequently Asked Questions
Can I work part-time and keep my SSDI benefits?
Yes, as long as your monthly earnings stay below the SGA threshold. Many people on SSDI work part-time and earn less than $1,550 per month (in 2024). You must report your work to Social Security, but part-time work below the SGA limit does not affect your benefits.
What if I earn above SGA for just one month?
One month above SGA does not automatically end your benefits. Social Security reviews your case to see whether your earnings show you can do substantial work consistently. If it was a one-time bonus or temporary project, they may not count it as proof of substantial work. You should still report it to Social Security.
Do I lose all my back pay if I earn above SGA?
No. If Social Security determines your earnings show you can work and stops your benefits, you keep all the benefits you already received. You only lose benefits going forward from the month they decide your case. You do not have to repay past benefits unless you did not report your work and were overpaid.
Can I use my Trial Work Period months all at once or do they have to be spread out?
You can use them however works for you. Your nine Trial Work Period months do not have to be consecutive. You could use three months, stop working for a while, then use the remaining six months later. Social Security tracks which months count toward your nine-month total.
What counts as self-employment income for SSDI?
Social Security counts your net profit from self-employment—the money you make after subtracting business expenses. If you run a business and earn $3,000 but spend $1,500 on supplies and overhead, your net profit is $1,500. That is what they count toward the SGA threshold.
