A lot of people assume the answer is no thinking that you have to be completely out of work before you can even think about filing for SSDI. So they keep pushing through, keep showing up, keep trying to make it work, until they physically can’t anymore.
That assumption costs people. Sometimes a lot.
The real answer is more nuanced. Yes, you can apply for SSDI while you’re still working but whether that works in your favor depends almost entirely on how much you’re earning. There’s a specific monthly threshold the SSA uses, and everything hinges on which side of it you fall on.
The Number That Matters: Substantial Gainful Activity
The SSA uses a measure called Substantial Gainful Activity, or SGA, to determine whether someone is working too much to qualify for disability benefits. It’s a monthly earnings threshold that gets adjusted annually.
For 2025, the SGA limit for non-blind applicants was $1,550 per month in gross earnings. For people who are blind, the threshold is higher, set at $2,590 per month.
If you’re working and earning less than the SGA limit, the SSA does not automatically consider you ineligible. Your application can still move forward and your case gets evaluated on its medical merits. If you’re earning above the limit, the SSA will generally find that you’re engaged in substantial work and deny the claim at the outset, before they even look at your medical records.
That’s the threshold. It’s not a suggestion. It’s the line the SSA draws before anything else gets considered.
Gross Earnings, Not Take-Home
One thing worth understanding clearly. The SGA calculation is based on gross earnings, meaning your income before taxes and deductions come out. Not what lands in your bank account after withholding.
If your gross monthly pay is $1,600 but your take-home is $1,300, the SSA looks at $1,600 which puts you over the 2025 limit. The net amount doesn’t factor in.
For hourly workers, the math is straightforward. For people with irregular hours, tips, commissions, or multiple part-time jobs, it requires a little more attention. Add up everything coming in for the month before any deductions and that’s the number you’re working with.
What If Your Hours Were Cut Because of Your Condition
This is a situation that comes up constantly and it’s worth addressing directly.
A lot of people don’t stop working all at once. Their condition gets worse gradually. They start calling out more, cut back to part-time or switch to something less physically or mentally demanding. They’re still working, technically, but they’re working less and earning less than they were before things got bad.
If that reduction in hours or earnings happened because of your condition, that context matters. It becomes part of the picture the SSA evaluates when they look at your work history and your onset date. A documented pattern of declining work capacity due to a medical condition is relevant evidence, not a mark against you.
It also affects back pay calculations. If your condition caused you to scale back significantly before you stopped working entirely, the onset date could potentially be established earlier than your last day of work, which means more back pay if you’re eventually approved.
Impairment-Related Work Expenses
Here’s something most people filing on their own never know about. The SSA allows certain disability-related work expenses to be deducted from your earnings before the SGA calculation is applied.
These are called Impairment-Related Work Expenses, or IRWEs. The basic idea is that if you have to spend money specifically because of your disability in order to work, that spending can reduce your countable earnings for SGA purposes.
Examples of what qualifies include medications you take to manage your condition well enough to work, medical equipment or devices you need at your job, transportation costs if your disability prevents you from using standard transportation, attendant care services, and certain home modifications that allow you to get to work.
The expenses have to be directly related to your disability and necessary for you to work. They can’t be general living expenses. But for people who are close to the SGA threshold, IRWEs can sometimes be the difference between being over the limit and being under it. That’s worth knowing before you assume you don’t qualify.
Self-Employment Is More Complicated
If you work for yourself, the SGA calculation works differently. The SSA doesn’t just look at what you earned. They look at the value of the work you actually performed and the time you put in, not just the income that came out of it.
A self-employed person can have a low-income month and still be found to be engaging in substantial gainful activity if the SSA determines the work itself was substantial. On the flip side, someone whose business generates significant revenue but who is personally able to do very little of the work due to their condition may be evaluated differently than the dollar amount alone would suggest.
Self-employment situations require a closer look at the specifics. The SSA uses three tests to evaluate self-employment for SGA purposes, and which test applies depends on the circumstances. If self-employment is your situation, it’s worth getting guidance on how those tests work before you file rather than making assumptions based on your income alone.
Applying While Working: What the Process Actually Looks Like
If your earnings are below the SGA threshold and you decide to file, the application process itself doesn’t look dramatically different from filing after you’ve stopped working entirely.
You’ll document your medical condition, your work history, your current limitations. The fact that you’re still working will be part of the picture. The SSA will look at whether your ability to work has been affected by your condition, how your current job compares to what you did before your health changed, and whether what you’re doing now constitutes substantial work under their standards.
One thing to be aware of. The SSA may look at your current work as evidence about your functional capacity. If you’re still performing a job that requires significant physical or cognitive demands, that gets factored into the evaluation of your limitations. This doesn’t automatically hurt your case but it does mean the medical documentation of your limitations needs to be thorough and specific about what you can and can’t do, not just what your diagnosis is.
What Happens If You Stop Working After You File
Some people file while still working and then stop working before a decision is made. That’s a common sequence and it doesn’t create a problem with your claim.
If anything, stopping work during the application process because your condition made it impossible to continue is additional evidence that your disability is genuinely preventing substantial employment. Document the reason for stopping as close to the time it happens as possible. A note from your doctor around the time you stopped working, explaining that your condition necessitated it, becomes part of the medical record in a useful way.
Let the SSA know about the change in your work status when it happens. Your application reflects your situation at the time of filing but your situation at the time of the decision matters too. Keeping the SSA current on significant changes is part of the process.
The Bigger Mistake People Make
Waiting. That’s it. That’s the biggest mistake.
People who are still managing to work, even partially, even at reduced capacity, often talk themselves out of filing because they don’t feel like they qualify yet. Or they feel like applying while still working would look bad. Or they’re worried about what it means to officially say they can’t work when they’re technically still showing up somewhere.
What they don’t think about is the onset date. Every month that passes between when your condition became genuinely disabling and when you file is a month you can’t recover in back pay. The SSA caps back pay at twelve months before your filing date. Waiting six months to file because you’re not sure you’re ready costs you six months of potential back pay if you’re eventually approved.
You don’t have to be certain you’ll be approved to file. Most people who get approved weren’t certain when they started. What matters is getting your filing date on record while the back pay window is still as wide as possible.
Finding Out Where You Actually Stand
If you’re still working and wondering whether your situation might qualify, the honest answer is that it depends on specifics that are hard to evaluate in general terms. Your earnings relative to the SGA threshold, the nature of your condition, your work history, what your medical records actually document.
A free evaluation can give you a clearer picture of whether your situation is worth pursuing and what the process would look like for your specific circumstances. There’s no cost involved and no obligation. And knowing sooner rather than later gives you more time to act if it makes sense to move forward.
