The basic earnings limit: $1,550 per month in 2024

Social Security Disability Insurance (SSDI) has a substantial gainful activity (SGA) limit. If you earn more than this amount in a month, Social Security will assume you can work and may stop your benefits. For 2024, the SGA limit is $1,550 per month for non-blind disabled workers. This figure changes each year based on national wage averages.

The limit applies to your gross earnings—the money before taxes are taken out. It does not matter whether you work one job or multiple jobs; Social Security adds them together. If you earn $1,551 in a single month, that one month can trigger a work activity review, though one month over the limit does not automatically end your case.

The SGA limit is higher for blind workers: $2,590 per month in 2024. If you are blind and working, you have more room to earn before Social Security reviews your case. The rules also differ slightly for workers who became disabled before age 22 and are receiving benefits on a parent's record.

Key Takeaways

  • You can earn up to $1,550 per month (2024) without triggering a work activity review, but earnings above that amount may lead Social Security to examine whether you can still work.
  • The limit resets each month—a high-earning month does not carry over, so you could earn $2,000 one month and $500 the next without penalty.
  • Work incentives like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can reduce your countable earnings and let you work more while keeping benefits.
  • The Trial Work Period lets you test your ability to work for nine months without any earnings limit, though you must report all work to Social Security.
  • After the Trial Work Period ends, you enter the Extended may be able to access Period, during which you keep benefits for nine more months even if you earn above the SGA limit.

The Trial Work Period: nine months with no earnings cap

When you first start working after becoming disabled, you enter a Trial Work Period (TWP). During this nine-month window, you can earn any amount without losing benefits. Social Security does not count earnings against you during the TWP, and you do not have to report monthly earnings—only that you are working.

The nine months do not have to be consecutive. Social Security counts only months in which you earn $940 or more (2024) as a TWP month. If you earn $939 in a month, that month does not count toward your nine. This means you could use your TWP over several years if you work part-time or take breaks.

You must tell Social Security that you are working, but you do not lose benefits during the TWP no matter how much you earn. This period is designed to let you test whether you can sustain work without the fear of losing your safety net when ready.

Extended may be able to access Period: nine more months of partial protection

After your nine Trial Work Period months end, you enter the Extended may be able to access Period (EEP), which lasts nine more months. During the EEP, you keep your SSDI benefits for any month in which you earn less than the SGA limit ($1,550 in 2024), even if you earned above it in other months.

The EEP gives you a second cushion. If you have a high-earning month during the EEP, you lose benefits only for that month—you do not lose them for the whole year. Once the EEP ends, the standard SGA rule takes over: if you earn above $1,550 in any month, Social Security will review whether you can work.

Like the TWP, the EEP months do not have to be consecutive. If you work part-time and dip below the SGA limit some months, those months count toward your nine-month EEP window.

Work incentives that reduce your countable earnings

Impairment Related Work Expenses (IRWE) are costs you pay to work because of your disability. If you need a personal assistant, special transportation, medication, medical equipment, or therapy to do your job, you can deduct those costs from your gross earnings. Social Security then counts only the remaining amount toward the SGA limit.

For example, if you earn $2,000 per month but pay $600 for a personal care attendant to help you at work, your countable earnings are $1,400—below the SGA limit. IRWE deductions can be substantial, but you must document them carefully and report them to Social Security.

Plans to Achieve Self-Support (PASS) let you set aside income and resources for a work goal without losing benefits. If you are saving toward education, equipment, or business startup costs, you can exclude that money from your earnings calculation. A PASS is more complex to set up—it requires a written plan and Social Security approval—but it can let you work and save aggressively while staying on benefits.

Expedited Reinstatement protects you if you stop working and your benefits end. Within five years, you can return to work and have your benefits restarted without a new process, as long as your medical condition has not improved. This is a safety net if you try work and find you cannot sustain it.

What happens when you earn above the SGA limit

If you earn more than $1,550 in a month after your Trial Work Period and Extended may be able to access Period end, Social Security will not automatically stop your benefits that month. Instead, they will send you a letter asking you to report your work activity. They want to know whether you are still disabled and whether your earnings show you can do substantial work.

Social Security looks at the nature of your work, not just the amount you earn. Earning $2,000 per month at a job you can do only because of accommodations or support may not be "substantial gainful activity" in their eyes. They also consider whether your earnings are temporary or sustainable.

If Social Security decides you are performing substantial gainful activity, they will stop your benefits. You have the right to request reconsideration and explain why you believe you are still disabled despite the earnings. Many people win reconsideration by showing that their work is not sustainable or that they need ongoing support to do it.

Reporting your work to Social Security

You must report all work to Social Security, even during the Trial Work Period when there is no earnings limit. Report your job start date, employer name, expected hours per week, and expected monthly earnings. You can report by phone, mail, or online through your my Social Security account.

Social Security uses your reports to track your TWP months and to monitor whether you stay below the SGA limit. If you do not report work and Social Security discovers it later, they may overpay you and ask for the money back, or they may stop your benefits retroactively.

If your earnings change—you get a raise, cut back hours, or lose a job—report the change. Social Security needs current information to calculate your benefits correctly and to know when your TWP months are being used.

Self-employment and business income

If you are self-employed, Social Security counts your net profit (income minus business expenses) toward the SGA limit. The calculation is more complex than wage work because you must document all business expenses and prove they are legitimate.

Social Security also looks at whether you are doing substantial work in your business, not just earning money. If you own a business but do not work many hours in it, or if someone else runs it for you, the earnings may not count as your work activity. This is an area where the rules are fact-specific, and it often helps to have a work incentives planning specialist review your situation.

Frequently Asked Questions

Can I work part-time and keep all my SSDI benefits?

Yes, if you earn less than $1,550 per month (2024) after your Trial Work Period and Extended may be able to access Period end. During those two periods, you can earn any amount. Many people work part-time indefinitely while on SSDI by staying below the SGA limit.

What if I earn $1,600 one month and $1,400 the next?

The limit resets each month. The high-earning month may trigger a work activity review, but the lower month does not offset it. Social Security looks at each month separately. If you consistently earn above $1,550, they will likely review your case.

Do I lose all my benefits if I go over the SGA limit?

Not when ready. Social Security will contact you and ask about your work. If they decide you are performing substantial gainful activity, your benefits stop. You can request reconsideration and explain why you believe you are still disabled despite the earnings.

How do I know if my work expenses count as IRWE?

IRWE must be costs you would not pay if you were not working, and they must be necessary because of your disability. Examples include personal care attendants, special transportation, medications, and medical equipment. Contact your local Social Security office or a work incentives planning specialist to review your specific expenses.

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

They can be spread out. Only months in which you earn $940 or more count as TWP months. You could use all nine months in one year, or you could use one or two per year over several years, depending on how much you work.
