What is the substantial gainful activity limit for SSDI in 2024?

Last updated 2026-07-10

What does substantial gainful activity actually mean?

Substantial gainful activity, almost always shortened to SGA, is Social Security's term for work that is both substantial (requires significant physical or mental effort) and gainful (done for pay or profit, or intended to be). The Social Security Act defines disability partly by reference to SGA: to qualify for SSDI, you must have a medically determinable impairment that prevents you from engaging in any SGA. ^[1]

That definition sounds simple but hides a lot of complexity. "Substantial" and "gainful" are each judged independently. A person who sweeps floors for two hours a day for $200 a month is doing gainful work but probably not substantial work by SSA's standards. A person who spends 40 hours a week doing unpaid volunteer work at a level equivalent to competitive employment could, in theory, be doing substantial work even though there's no paycheck. SSA has the authority to look past nominal wages in both directions.

The practical test SSA applies first is an earnings comparison. If your countable monthly earnings are above the SGA dollar threshold for the year, SSA presumes you're doing SGA. If they're below, SSA looks at the nature of the work itself before concluding you're not doing SGA. So the dollar figure is the starting point, not the ending point. ^[1]

SGA is evaluated at step one of SSA's five-step sequential evaluation process. If you're currently working above SGA, SSA stops right there and denies the claim. You never get to the medical or vocational analysis. That's why understanding this threshold before you file, or before you take on part-time work while waiting for a decision, matters so much.

What is the exact 2024 SGA dollar limit for SSDI?

The 2024 SGA limit is $1,550 per month for non-blind disabled workers and $2,590 per month for individuals who meet SSA's definition of statutory blindness. ^[2]

Those figures are gross countable earnings before income tax, not take-home pay. SSA compares your gross wages (or net self-employment profit after business expenses but before taxes) to the threshold. The blind limit is higher because Congress specifically legislated a more generous standard for blind claimants in 42 U.S.C. § 423(d)(4). ^[1]

SSA adjusts both figures annually using the national average wage index, which means the limit changes most years. The 2024 non-blind threshold rose $80 from the 2023 figure of $1,470. If you filed in late 2023 and your claim carried into 2024, SSA applies whichever year's limit corresponds to the time period being evaluated.

Here's the number to memorize: $1,550. If your gross monthly earnings clear that line, SSA will find you're doing SGA and deny your claim at step one, regardless of how severe your condition is. If you're under that line, the evaluation moves forward to your medical impairments.

How has the SGA limit changed from 2020 to 2024?

The SGA limit rises most years but not always dramatically. The table below shows the non-blind and blind SGA thresholds for the last five years. ^[2]

Year	Non-Blind SGA Limit	Blind SGA Limit
2020	$1,260/month	$2,110/month
2021	$1,310/month	$2,190/month
2022	$1,350/month	$2,260/month
2023	$1,470/month	$2,460/month
2024	$1,550/month	$2,590/month

The jump from 2022 to 2023 was larger than usual because the national average wage index surged during that period. The 2024 increase was more modest at $80 for non-blind workers. SSA publishes the new figures each fall, typically in October or November, alongside the COLA announcement. ^[2]

If you're trying to plan part-time work while your claim is pending, pay attention to the year, more than the generic figure you read somewhere online. Many older articles still quote the 2022 or 2023 number, and the difference of a few hundred dollars per month can change the outcome of your case.

What counts as earnings for the SGA calculation?

SSA counts gross wages from employment and net earnings from self-employment, but not all money you receive is counted at face value. There are several adjustments SSA makes before comparing your earnings to the SGA threshold. ^[3]

First, SSA can subtract "impairment-related work expenses" (IRWEs). These are out-of-pocket costs for items or services you need because of your disability in order to work. Examples include medication co-pays, specialized transportation, attendant care costs, and adaptive equipment. If you pay $200 a month out of pocket for a medication you need to tolerate your work schedule, SSA subtracts that $200 from your gross wages before comparing to the SGA limit. ^[3]

Second, SSA may apply a "subsidy" if your employer is paying you more than your actual work is worth because of your impairment. This happens most often with a supportive employer or in a sheltered work setting. If SSA determines you're receiving a subsidy, they count only the reasonable value of the work you actually perform, not the full paycheck.

Self-employment income gets more complicated. SSA uses one of three tests for self-employed individuals: the countable income test, the three-tests approach (significant services and substantial income, comparability, or worth of work), or both. Net profit after legitimate business deductions is the starting point, but SSA may still find SGA even if your net profit is low if you're providing substantial services.

Tips, bonuses, and sick pay all count. Money from investments, rental income, spousal earnings, and Social Security payments do not count toward SGA. The IRS and SSA don't use the same definitions, so what's taxable income to the IRS isn't always countable earnings under SGA rules. ^[3]

Does the SGA limit apply to SSI as well as SSDI?

No. This is one of the most common points of confusion in the disability system.

SSI, Supplemental Security Income, uses an entirely different earnings framework. SSI doesn't use the SGA test at step one the way SSDI does. Instead, SSI uses a countable income calculation that reduces your monthly benefit dollar-for-dollar after certain exclusions. SSA excludes the first $65 of earned income per month plus half of anything above that. So you can earn some money and still receive a partial SSI payment. ^[4]

For SSDI, by contrast, SGA is binary at the application stage: either you're above the threshold and get denied at step one, or you're below it and the evaluation continues. Once you're approved for SSDI, there's a trial work period (TWP) and then an extended period of eligibility that introduce more nuance, but during the application process SGA is a hard gate.

The $1,550 figure for 2024 applies specifically to SSDI applicants and to continuing disability reviews for SSDI recipients who return to work. If you're on SSI and working, you use the SSI earned income exclusion rules, not the SGA limit. ^[4]

Some people receive both SSDI and SSI simultaneously (called concurrent benefits). For them, SSA applies the SGA test to the SSDI side and the earned income rules to the SSI side. They're evaluated separately.

What happens if you earn just over the SGA limit while your claim is pending?

If you're working and earning above $1,550 per month (gross, countable) in 2024, SSA will deny your claim at step one. Period. The denial letter will cite SGA as the reason. Your medical records may never be reviewed at all.

If you're close to the threshold, say earning $1,400 to $1,600 a month, it's worth calculating your countable income carefully before SSA does it for you. Subtract any IRWEs, ask whether your employer is providing a subsidy, and look hard at whether your net earnings actually exceed the limit. A small overage that results from a miscalculation you could have corrected is frustrating to lose a case over.

If you get denied for SGA, you can appeal. At reconsideration and the ALJ hearing level, you can present evidence that your countable earnings were actually below the threshold after proper deductions. ^[5] This is one of the cleaner appeals because it's a math problem with a defined answer, not a subjective medical judgment.

One thing many applicants don't know: SSA looks at the period of alleged disability, more than the month you apply. If you stopped working six months ago and are earning nothing now, SGA isn't an issue for the current period. But if you were working above SGA during part of the period you claim as disabled, SSA will examine that period carefully.

How does SGA work during the trial work period for current SSDI recipients?

If you're already receiving SSDI and want to try returning to work, SSA provides a trial work period (TWP) of nine months (not necessarily consecutive) within a rolling 60-month window. During the TWP, you can earn any amount without triggering SGA. ^[6]

In 2024, a month counts as a TWP service month if your earnings exceed $1,110 (a separate threshold from the SGA limit). After you use up all nine TWP months, SSA begins evaluating whether you're doing SGA. If you are, your benefits can stop after a three-month grace period.

After the TWP, there's a 36-month extended period of eligibility (EPE). During the EPE, you can receive benefits for any month your earnings drop below SGA. This gives you some flexibility to try work, fall back to benefits if it doesn't work out, and try again without a full new application.

None of this applies to applicants who haven't been approved yet. The TWP is only for people already on SSDI. If you're in the application process, the $1,550 SGA limit is what matters. ^[6]

If you're weighing a return to work while on SSDI, SSA's Ticket to Work program offers free employment support services through approved providers. That's a resource worth knowing about, separate from the SGA calculation itself. ^[6]

Can working below the SGA limit hurt your SSDI claim in other ways?

Yes, though the risk is different from outright SGA denial.

If you're working part-time and earning under $1,550 a month, you clear the step-one hurdle. But your work activity still goes into the record. At step five of the evaluation, SSA assesses whether you can do any work that exists in significant numbers in the national economy. If you're actually doing a job, even part-time, that job becomes evidence about what you're capable of. An ALJ might look at the work you're currently performing and conclude it shows you have more functional capacity than your medical records suggest.

This is a real tension in the system. Working below SGA shows you're trying to support yourself and isn't supposed to be held against you. But it does create a factual record. If your job requires lifting 20 pounds and you're claiming you can only lift 10, that's a problem.

The way to handle this is to make sure your medical records accurately reflect your limitations, including any accommodations your employer makes for you, any days you miss due to your condition, and any tasks you're relieved of. If your employer lets you sit when others stand, or gives you a lighter workload, get that documented. It shows the work isn't representative of competitive employment.

A tool like DisabilityFiled's guided intake can help you think through how to describe your work history accurately in your application, which matters more than many applicants realize. Getting the work history section right is often where strong cases get inadvertently weakened.

What is the SGA limit for 2025, and what's expected after that?

SSA announced the 2025 SGA limit at $1,620 per month for non-blind individuals and $2,700 per month for blind individuals. ^[2] That's a $70 increase over 2024 for non-blind workers.

The adjustment follows the national average wage index, which SSA finalized in fall 2024. The formula is set by statute, so Congress doesn't have to vote on it each year. It adjusts automatically.

If you're reading this in 2025, use $1,620 as your working number for SSDI SGA. The 2024 figure of $1,550 still applies if SSA is reviewing a period of work that occurred in 2024.

There's no publicly announced projection for 2026 yet, but historically the non-blind SGA limit has risen between $50 and $130 per year, depending on wage growth. Nobody can tell you the exact 2026 figure until SSA announces it, probably in October or November 2025. Keep an eye on SSA's official SGA chart page for the update. ^[2]

How does SSA verify your earnings against the SGA limit?

SSA has several ways to find out what you're earning, and they use most of them.

The most direct source is your employer. SSA requests wage records from employers as part of disability reviews and continuing disability reviews. SSA also receives earnings data from the IRS annually through the Social Security earnings record. If you file a W-2 or a Schedule SE, that income is in SSA's system. ^[7]

For self-employed applicants, SSA typically asks for tax returns (Schedule C or Schedule F for farming) and may ask for bank statements or business records. Net profit after legitimate deductions is the starting point, but SSA can adjust upward if they believe you're underreporting.

During the application process, you'll be asked to list all work you've done in the past. SSA's form SSA-3368 (the Adult Disability Report) asks about your work history and current employment. If you're working above SGA and don't disclose it, SSA will likely find out through IRS data anyway. The better approach is to be accurate upfront.

For already-approved SSDI recipients, SSA requires you to report any work activity promptly. Failure to report can result in overpayments, which SSA will try to recover, sometimes years later. The duty to report work is ongoing, more than at the time of approval. ^[7]

Understanding your own SSDI payment amounts and how they could be affected is also worth reviewing. The social security disability benefits pay chart breaks down how monthly amounts are calculated.

What should you do if your earnings are close to the SGA limit?

If you're earning anywhere near $1,550 a month gross in 2024, you need to calculate your actual countable income before SSA does. Here's a practical checklist.

First, list your gross wages or net self-employment profit. If you're an employee, that's your gross pay before taxes, not your net check. If self-employed, it's net profit after business expenses on your Schedule C or F.

Second, identify every impairment-related work expense you're paying out of pocket. These must be costs you incur specifically because of your disability in order to work. Co-pays, attendant care, special transportation, adaptive equipment. Document each with receipts. SSA won't give you credit for expenses you claim but can't document. ^[3]

Third, look at whether your employer is accommodating you in ways that make your actual job easier than a competitive, unaccommodated worker's job would be. If so, the "subsidy" concept may apply, and SSA might count only the fair market value of your actual output, not your full paycheck.

Fourth, if after all those adjustments you're still above $1,550, talk to a disability attorney or advocate before filing. Most disability attorneys offer free consultations, and many work on contingency, meaning you pay nothing unless you win. They can help you analyze whether to postpone filing, reduce hours, or structure your situation differently.

If you're ready to file and want to make sure you document everything correctly, working through a structured intake process, like the one at DisabilityFiled, helps ensure you don't miss details about work history and impairment-related expenses that affect how SSA evaluates your earnings.

Where do you find the official SGA figures and SSDI rules?

SSA maintains an official SGA table that lists the non-blind and blind thresholds going back to 1975. You can find it at ssa.gov under the "Substantial Gainful Activity" page. That's the authoritative source. ^[2]

For the legal framework, the statutory definition of disability referencing SGA appears in 42 U.S.C. § 423(d)(1)(A) for SSDI. The SSA Program Operations Manual System (POMS), specifically DI 10501.015, covers the SGA evaluation for employed individuals in detail. ^[3] POMS is publicly available at policynet.ssa.gov and is the same internal manual SSA claims examiners use. If you want to understand exactly how a decision-maker at SSA is supposed to evaluate your earnings, that's the document to read.

The SSA Blue Book (Listing of Impairments) is the reference for whether a medical condition meets or equals a listed impairment. That's step three of the five-step evaluation, separate from SGA, but it's in the same disability determination process. ^[8]

For a broader look at how disability benefits work within the Social Security system, and how SSDI fits alongside other programs, there are more resources worth reviewing. The apply for social security disability guide walks through the full application process from start to finish.

Frequently asked questions

What is the SGA limit for SSDI in 2024?

The 2024 SGA limit is $1,550 per month for non-blind SSDI applicants and $2,590 per month for individuals who meet SSA's statutory blindness definition. These are gross countable earnings figures before income tax. If your countable monthly earnings exceed the relevant threshold, SSA will deny your claim at step one of its five-step evaluation without reviewing your medical records.

What is the SGA limit for blind individuals in 2024?

Blind SSDI claimants face a higher SGA threshold of $2,590 per month in 2024. Congress set a more generous standard for blind workers in 42 U.S.C. § 423(d)(4). This is not automatic; you have to meet SSA's specific definition of statutory blindness, which means central visual acuity of 20/200 or less in the better eye with best correction, or a visual field of 20 degrees or less.

Does gross or net income count toward the SGA limit?

For employees, SSA uses gross wages before taxes. For self-employed individuals, SSA starts with net profit after legitimate business expenses (as reported on Schedule C or F) but may apply additional adjustments. Either way, SSA can subtract impairment-related work expenses and employer subsidies before comparing the resulting figure to the $1,550 threshold.

Can I work part-time and still qualify for SSDI?

Yes, if your countable monthly earnings stay below the SGA limit ($1,550 in 2024). Earning under that threshold means SSA won't deny your claim at step one. Your work history will still be part of the record and can affect later steps of the evaluation, so it's worth documenting any accommodations your employer makes, hours missed due to your condition, and physical or mental limitations on the job.

What are impairment-related work expenses and how do they reduce my SGA calculation?

Impairment-related work expenses (IRWEs) are out-of-pocket costs for items or services you need specifically because of your disability in order to work. SSA subtracts documented IRWEs from your gross earnings before comparing them to the SGA threshold. Examples include medication co-pays, attendant care, specialized transportation, and adaptive equipment. You need receipts or other documentation; SSA won't deduct undocumented expenses.

Does the SGA limit apply during the trial work period for SSDI?

No. During the trial work period (TWP), you can earn any amount without losing SSDI benefits. A month counts as a TWP month in 2024 if earnings exceed $1,110 (a separate, lower threshold). Once you've used all nine TWP months within a 60-month window, SSA begins applying the regular $1,550 SGA limit. The TWP applies only to people already approved for SSDI, not to applicants.

What is the SGA limit for 2025 compared to 2024?

The 2025 SGA limit is $1,620 per month for non-blind workers and $2,700 per month for blind individuals, up from $1,550 and $2,590 in 2024. SSA adjusts the figures annually using the national average wage index and announces the new amounts each fall. If SSA is reviewing work activity that occurred in 2024, the 2024 figures apply to that period.

Does the SGA limit apply to SSI, or just SSDI?

The $1,550 SGA limit applies to SSDI, not SSI. SSI uses a different system: SSA excludes the first $65 of monthly earned income plus half of anything above that, then subtracts the remainder from your maximum SSI payment. You can receive a reduced SSI benefit even with moderate earnings, whereas SSDI uses SGA as a binary gate at the application stage.

What happens if SSA finds I was earning above the SGA limit?

SSA will deny your application at step one, citing SGA. The denial letter will explain the finding. You can appeal through reconsideration and then an ALJ hearing. On appeal, you can present evidence that your countable earnings were actually below the threshold after IRWEs, subsidies, or other adjustments are applied. If you're already approved for SSDI and fail to report work above SGA, SSA may assess an overpayment.

How does SSA find out how much I'm earning?

SSA receives annual earnings data from the IRS through your W-2 and Schedule SE filings. For current claims, SSA can contact your employer directly to verify wages. For self-employed individuals, SSA typically requests tax returns and may ask for bank statements. You're also required to report work activity on your disability application and, once approved, on an ongoing basis. Underreporting can lead to overpayment recovery.

If I stop working just before I apply, does SGA still affect my SSDI claim?

SSA looks at the period of alleged disability, more than the filing date. If you stopped working recently and your onset date is the day you stopped, SSA will evaluate SGA from your onset date forward. If you were earning above SGA at any point within the period you claim as disabled, SSA will scrutinize that period. Stopping work just before filing is fine, but SSA may question why you stopped and whether your impairment, not a choice, is the reason.

Can self-employment income push me over the SGA limit even if my business isn't profitable?

Possibly. SSA uses three tests for self-employment SGA. If your business isn't profitable but you're providing significant services to it, SSA may still find SGA based on the value of your work rather than your net income alone. This is the "significant services and substantial income" or "worth of work" test. A low Schedule C profit doesn't automatically mean you're below SGA if you're clearly operating a real business.

Where can I find the official SSA table of SGA limits by year?

SSA maintains a publicly available table of SGA limits dating back to 1975, listed separately for non-blind and blind claimants. You can find it on SSA's website by searching "substantial gainful activity" on ssa.gov. The POMS section DI 10501.015 contains the detailed policy rules SSA examiners follow when evaluating employed claimants' earnings. Both are free and publicly accessible.

Does investment income or a spouse's earnings count toward my SGA limit?

No. Investment income (dividends, interest, capital gains), rental income, and your spouse's earnings do not count toward your SGA calculation. SSA's SGA analysis is limited to earnings from your own work activity, either as an employee or self-employed person. Unearned income of any kind, and income belonging to other household members, is excluded from the SGA comparison entirely.
