The Earnings Limit That Matters: The Substantial Gainful Activity Threshold

Social Security has one main rule about work and SSDI: if you earn more than a set amount per month, Social Security will assume you are no longer disabled and will stop your benefits. That amount is called the Substantial Gainful Activity (SGA) threshold, and it changes every year.

For 2024, the SGA threshold is $1,550 per month if you are blind, and $1,470 per month if you are not blind. These are gross earnings — the amount before taxes are taken out. If you earn more than this in a single month, Social Security counts that month as a month of work, and your benefits may be affected depending on where you are in the process of returning to work.

The threshold applies to what you actually earn, not what you are offered or what the job pays. If you work part-time or earn less than the threshold, you keep your full SSDI payment. If you cross the threshold, the rules change based on whether you are still in a trial work period or have moved into the extended period of may be able to access.

Key Takeaways

  • You can earn up to $1,470 per month (or $1,550 if blind) in 2024 without triggering a work rule, but this threshold increases each January.
  • The nine-month trial work period lets you test your ability to work at any earnings level without losing benefits, but you must report all work to Social Security.
  • After the trial work period ends, you enter the 36-month extended period of may be able to access, during which months over the SGA threshold count against your benefits.
  • If you stop working or drop below the threshold, you can restart benefits within five years without a new medical review.
  • Work incentives like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can reduce your countable earnings and extend your work window.

The Trial Work Period: Nine Months to Test Your Work Capacity

When you first return to work while on SSDI, you enter a nine-month trial work period. During these nine months, you can earn any amount — there is no earnings limit. You keep your full SSDI check every month, no matter how much you make. The only requirement is that you report your work to Social Security.

The nine months do not have to be consecutive. Social Security counts only the months in which you earn $240 or more (in 2024; this amount also adjusts yearly). If you work one month and then take two months off, you have used one month of your trial period. You can spread the nine months across several years if you need to.

This period exists to let you test whether you can actually sustain work without losing your benefits as a safety net. Many people use it to try part-time work, return to a previous job, or test a new field. If you discover you cannot work, you stop, report it to Social Security, and your benefits continue without interruption.

After the Trial Work Period: The Extended Period of may be able to access

Once your nine trial work months are used up, you move into the extended period of may be able to access, which lasts 36 months. During this time, the SGA threshold applies. Any month you earn $1,470 or more (if not blind) counts as a month of work.

Here is how it works: if you have 12 months of earnings at or above the SGA threshold within your 36-month window, Social Security will stop your benefits. The months do not have to be consecutive. If you earn $1,470 in January, take three months off, then earn $1,470 again in May, you have used two of your 12 months. You still have 10 months left before benefits stop.

If you drop below the threshold — by reducing hours, taking unpaid leave, or stopping work entirely — those months do not count. You can work indefinitely at $1,400 per month and never trigger a benefit termination. The extended period gives you a cushion: you can have months of higher earnings without losing coverage, as long as you do not hit 12 high-earning months before the 36 months end.

What Happens When Your Benefits Stop

If you use all 12 of your extended period months, Social Security will send you a notice that your benefits are stopping. This is not permanent. You have a five-year period during which you can restart benefits without a new medical review, as long as you report that you can no longer work or that your earnings have dropped below the SGA threshold.

The restart process is faster than the original process. You contact Social Security, explain that you need benefits again, and provide current earnings information. If you stopped working or your condition worsened, benefits usually restart within one to two months. You do not have to go through the full medical evaluation again.

After five years, if you have not restarted benefits, you would need to file a new SSDI process and go through the medical review process again. This is why it is important to contact Social Security before your five-year window closes if you think you will need benefits again.

Work Incentives That Reduce Your Countable Earnings

Impairment Related Work Expenses (IRWE) are costs you pay because of your disability that allow you to work. Examples include special transportation to get to work, medication you need to work, medical equipment, or a personal assistant. You can deduct these expenses from your gross earnings, which lowers the amount Social Security counts toward the SGA threshold.

If you earn $1,600 per month but spend $200 on disability-related work costs, Social Security counts only $1,400 as your earnings. This keeps you below the threshold even though your gross pay is higher. You must document these expenses and report them to Social Security; they do not happen automatically.

Plans to Achieve Self-Support (PASS) let you set aside income and resources for a specific work goal — like training for a new job, buying equipment, or starting a business. Money in a PASS plan does not count as income for SSDI purposes. If you are saving $500 per month toward a vocational certificate, that $500 does not count against your earnings limit. PASS plans require a written agreement with Social Security and must have a clear endpoint and goal.

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. Failure to report can result in overpayments you will have to repay, or suspension of benefits. Social Security wants to know your start date, your employer, your job title, and your expected monthly earnings.

You can report work by phone, mail, or online through your my Social Security account. Many people report once a month or whenever their earnings change. If you are unsure whether something counts as work — such as self-employment, volunteer work, or family business — contact your local Social Security office. It is better to report and ask than to assume.

Social Security also has a Ticket to Work program, which extends your work incentives and gives you access to employment support services. If you use your Ticket, you get an additional 60-month extended period of may be able to access after your first 36 months end, giving you more time to test your work capacity. This is optional, but it can be valuable if you are working toward long-term employment.

How Self-Employment Earnings Count

If you are self-employed, Social Security counts your net profit — the money left after business expenses — not your gross revenue. You will need to keep records of income and expenses, usually through tax returns or business records. Self-employment can be harder to report because earnings fluctuate, but the same trial work period and extended period rules explore.

During your trial work period, you can earn any amount from self-employment. Once you enter the extended period, months in which your net profit exceeds the SGA threshold count against your 12-month limit. If you own a business that generates $2,000 per month in net profit, that counts as a work month even if you only spend a few hours per week on it.

Frequently Asked Questions

Can I work part-time and keep my full SSDI check?

Yes, if you earn less than $1,470 per month (in 2024, if not blind). You can work part-time indefinitely at this earnings level and receive your full benefit. During your nine-month trial work period, you can earn any amount and keep your full check.

What if I earn over the limit one month but not the next?

Only the months you earn at or above the SGA threshold count. If you earn $1,600 in January and $800 in February, January counts as one work month toward your 12-month limit, but February does not. You can have months of lower earnings without penalty.

Do I have to report my work if I am still in the trial work period?

Yes. Even though there is no earnings limit during the trial period, you must report all work to Social Security. Failure to report can cause overpayments and suspension of benefits. Report your start date, employer, and expected monthly earnings.

What if my disability gets worse and I have to stop working?

Contact Social Security when ready. If you stop work or your earnings drop below the SGA threshold, your benefits can continue or restart. You do not lose your extended period months just because you stop working; the clock keeps running for 36 months from when your trial period ended.

Can I use work incentives like IRWE if I am self-employed?

Yes. If you are self-employed and have disability-related work expenses — such as special equipment, transportation, or information — you can deduct them from your net profit. You must document and report these expenses to Social Security.
