The basic rule: substantial gainful activity limits

Social Security sets a monthly earnings threshold called substantial gainful activity, or SGA. In 2024, that threshold is $1,550 per month for most people receiving SSDI, and $2,590 per month if you are blind. If you earn more than that amount in a month, Social Security will assume you are working at a level that means you should not be receiving disability benefits, and your case may be reviewed or your benefits may stop.

The threshold changes each year based on national wage trends. Social Security publishes the new figure in December for the following year. The SGA limit applies to your gross earnings—the money you make before taxes or deductions—not what you take home.

Earning below the SGA limit does not automatically mean your benefits continue. Social Security also looks at whether your work shows you can do substantial work despite your condition. But the SGA threshold is the clearest, most concrete line: cross it, and your case gets flagged for review.

Key Takeaways

  • You can earn up to $1,550 per month (or $2,590 if blind) in 2024 without triggering an automatic review of your disability status.
  • The SGA limit is based on gross income before taxes, and it changes each January based on wage data from the previous year.
  • Work incentives like the Trial Work Period and Extended may be able to access Period let you test your ability to work without losing benefits when ready.
  • Self-employment income counts toward the SGA limit, and Social Security calculates it differently than W-2 wages.
  • Certain types of income—such as gifts, loans, and some housing information—do not count toward your earnings limit.

What counts as earnings for SSDI purposes

Social Security counts wages from a job, net profit from self-employment, and certain other forms of work income. If you are paid by an employer, your gross wages count, regardless of how many hours you work or whether the job is part-time or full-time. Bonuses, commissions, and paid leave all count as earnings in the month you receive them.

Self-employment income is calculated as your net profit—total revenue minus ordinary and necessary business expenses—divided by the number of months you worked. If you own a business or do freelance work, you will need to track expenses carefully, because Social Security will ask for tax returns and business records to verify your net income.

What does not count: gifts, loans, inheritances, investment income, rental income (in most cases), workers' compensation, unemployment benefits, Supplemental Security Income (SSI), other Social Security benefits, and certain housing or food information. If you receive a lump-sum payment—such as a settlement or back pay—Social Security counts it in the month you receive it, which can push you over the SGA limit that month even if your regular earnings are lower.

The Trial Work Period: nine months to test your work capacity

SSDI includes a built-in work test called the Trial Work Period (TWP). During this nine-month window, you can earn any amount without losing your SSDI benefits, as long as you report your work to Social Security. The nine months do not have to be consecutive; Social Security counts only months in which you earn $1,050 or more (in 2024) as a trial work month.

The purpose is to let you see whether you can sustain work without the financial risk of losing your benefits when ready. Many people use the TWP to return to part-time work, test a new job, or gradually increase their hours. At the end of the nine months, your benefits do not stop automatically; instead, you enter the Extended may be able to access Period.

You must report your work and earnings to Social Security each month during the TWP. If you do not report, Social Security may not count the month toward your nine, or may overpay you and ask for the money back later. Contact your local Social Security office or your work incentives planning and information (WIPA) project to make sure you are reporting correctly.

Extended may be able to access Period: the 36-month safety net

After your nine-month Trial Work Period ends, you enter the Extended may be able to access Period (EEP), which lasts 36 months. During the EEP, you can still earn above the SGA limit without losing your benefits, but only for months in which you do not earn over the SGA threshold. In other words, you get 36 additional months to have some months where you earn above SGA without an automatic benefit termination.

Here is how it works in practice: suppose you earn $2,000 in January (above the $1,550 SGA limit). Your benefits stop for January. But you still have 35 more months in your EEP window. If you earn $1,400 in February (below SGA), your benefits resume. You can use your EEP months strategically—working more heavily in some months, less in others—as long as you do not exceed SGA in more than 36 months total during the EEP.

Once your EEP ends, the old rule returns: earn over SGA in any month, and your benefits stop. This is why planning with a benefits counselor or WIPA project is important; they can help you understand how many EEP months you have left and what your earnings strategy should be.

Impairment-Related Work Expenses and other deductions

Social Security allows you to subtract certain work-related expenses from your gross earnings before comparing your income to the SGA limit. These are called Impairment-Related Work Expenses (IRWE). They must be costs you would not have if you did not have a disability, and they must be necessary for you to work.

Examples include: attendant care or personal assistant services, medical devices or equipment needed for work, medications required to work, transportation costs related to your disability (such as paratransit), prosthetics, and workplace modifications. You cannot deduct general living expenses, childcare, or transportation to and from work unless it is specifically disability-related.

To claim an IRWE, you must provide documentation to Social Security: receipts, invoices, or statements from providers showing the cost and the disability-related reason. If you have significant work-related expenses, subtracting them can lower your countable earnings and keep you below the SGA limit. This is another area where a WIPA project or benefits counselor can help you identify and document expenses you might otherwise miss.

Plan to Achieve Self-Support: a path for higher earnings

If you want to work toward a goal that requires earnings above the SGA limit—such as starting a business, completing education, or reaching a specific job level—you may be able to use a Plan to Achieve Self-Support (PASS). A PASS is a written agreement between you and Social Security that sets out a work goal, a timeline, and how you will use your earnings to reach that goal.

While you are following an approved PASS, earnings set aside for your goal do not count toward the SGA limit. For example, if your goal is to complete a certificate program and you earn $2,500 per month but set aside $1,200 for tuition, only $1,300 counts toward SGA. A PASS can last up to 18 months and can be extended.

PASS plans require careful documentation and must be approved by Social Security before you start setting aside money. They are complex, and mistakes can result in overpayments. Work with a WIPA project or a benefits planning counselor to develop and submit your PASS; most of these services are free.

What happens if you earn over the limit

If you earn more than the SGA limit in a month, your SSDI benefits stop for that month. You do not lose your benefits permanently; they resume the next month if your earnings drop back below SGA. However, if you consistently earn above SGA, Social Security will eventually terminate your case and send you a notice explaining why.

Termination is not automatic or when ready. Social Security sends you a notice, gives you a chance to respond, and usually allows you to request a hearing before your benefits actually stop. But the process takes time, and you may receive overpayment notices asking you to repay benefits you received in months when you should not have.

If you think you will earn above SGA, report it to Social Security before it happens. Explain your work plan, ask about the Trial Work Period or Extended may be able to access Period, and ask whether a PASS or IRWE deduction might help. Being proactive prevents surprises and overpayments.

Frequently Asked Questions

Can I work part-time and still get SSDI?

Yes, as long as your monthly earnings stay below the SGA limit ($1,550 in 2024) or you are still within your Trial Work Period or Extended may be able to access Period. Many people on SSDI work part-time. The key is reporting your work to Social Security and understanding which months count toward your work incentive windows.

Do I have to report my earnings to Social Security?

Yes. You must report your work and earnings, especially during your Trial Work Period. Failure to report can result in overpayments, loss of benefits, or both. Contact your local Social Security office or your WIPA project to find out how and when to report.

What if I am self-employed—how do I calculate my earnings?

Self-employment earnings are your net profit (revenue minus ordinary business expenses) divided by the number of months you worked. You will need to provide tax returns and business records to Social Security. If you are starting a business, a PASS plan can help you set aside earnings for startup costs without them counting toward SGA.

Can I use my Trial Work Period months all at once, or do they have to be spread out?

Your nine Trial Work Period months do not have to be consecutive. Social Security counts only months in which you earn $1,050 or more (in 2024) as a trial work month. You can work heavily for three months, take a break, then work again—as long as you report each month you work.

What if I receive a large one-time payment, like a settlement or bonus?

Lump-sum payments count as earnings in the month you receive them. If the payment pushes you over the SGA limit, your benefits stop for that month. Plan ahead if you know a large payment is coming; ask Social Security whether you can split it across months or whether other work incentives explore.
