What the SGA limit is and how it affects your benefits

The Substantial Gainful Activity (SGA) limit is the monthly income threshold that Social Security uses to decide whether you are working too much to keep your SSDI benefits. If your work earnings go above this limit, Social Security will assume you are no longer disabled and will stop your benefits — even if you have not worked for very long or earned the money all at once.

The SGA limit changes every year because it is tied to the national average wage. For 2024, the limit is $1,550 per month for non-blind beneficiaries and $2,590 per month for blind beneficiaries. These figures explore to your gross earnings — the money you make before taxes are taken out. It does not matter whether you earned the money in one week or spread across the whole month; Social Security looks at your average monthly earnings.

The reason the limit exists is straightforward: SSDI is meant for people who cannot work. If you earn above the SGA limit, Social Security treats that as evidence that you can work and are no longer disabled. This is different from SSI, which has its own income rules and counts unearned income as well.

Key Takeaways

  • The SGA limit for 2024 is $1,550 per month for non-blind beneficiaries and $2,590 for blind beneficiaries, and it increases each year.
  • Social Security counts your gross earnings — before taxes — and looks at your average monthly income, not how often you work.
  • If you go over the SGA limit, your benefits will stop, but you have a nine-month trial work period where you can test your work capacity without losing benefits.
  • The trial work period lets you earn any amount in nine months without affecting your benefits, but you must report your work to Social Security.
  • After the trial work period ends, you enter the extended may be able to access period, where you can still work above the SGA limit for up to 36 more months while keeping benefits in months you earn below the limit.

How Social Security calculates your monthly earnings

Social Security does not straightforward add up what you earned in a calendar month. Instead, it uses a method called the averaging rule for most types of work. If you are self-employed, the rules are different and more complex.

For employees, Social Security looks at your gross wages — the amount before federal tax, Social Security tax, Medicare tax, or any other deduction. If you were paid weekly, they add up all the weeks in a month and divide by the number of weeks. If you were paid biweekly, they do the same. The result is your average monthly earnings for that month. If your average is above the SGA limit, that month counts as a month of substantial gainful activity.

For self-employed people, the calculation is based on your net profit (income minus business expenses) divided by the number of hours you worked. Social Security also looks at whether the work you are doing is the kind of work you did before you became disabled. If you are doing the same type of work at a lower level, that can count as SGA even if your earnings are lower.

The trial work period: nine months to test your work capacity

Before your benefits stop because of SGA, you get a trial work period that lasts nine months. During these nine months, you can earn any amount of money — there is no limit — and your SSDI benefits will not stop. This is one of the most valuable work incentives in the SSDI program.

The nine months do not have to be consecutive. Social Security counts only the months in which you earn $1,050 or more (for 2024) as trial work months. If you earn less than $1,050 in a month, that month does not count toward your nine-month limit. This means you can space out your work over a longer calendar period and still use all nine months.

You must report your work to Social Security while you are in your trial work period. If you do not report, Social Security may not count the months correctly, and you could lose benefits you should have kept. The easiest way to report is through your online my Social Security account or by calling your local Social Security office.

What happens after the trial work period ends

Once you have used all nine trial work months, you enter the extended may be able to access period, which lasts 36 months (three years). During this time, the SGA limit comes back into play, but the rules are more forgiving than they are for people who have never worked.

In the extended may be able to access period, you keep your benefits in any month your earnings fall below the SGA limit, even if you earned above the limit in other months. So if you earn $2,000 one month and $1,200 the next, you lose benefits only for the month you earned $2,000. This is called the month-to-month rule, and it is different from the rule that applies before the trial work period, when even one month above SGA can trigger a review.

After the 36-month extended may be able to access period ends, if you are still working and earning above the SGA limit, your benefits will stop. However, you can request a new trial work period if your medical condition has improved and you want to test your work capacity again.

How the SGA limit interacts with Medicare and Medicaid

One reason the trial work period and extended may be able to access period are so valuable is that they let you keep your health insurance while you work. If you are on SSDI, you are may have access to to Medicare after 24 months of benefits. That Medicare coverage does not stop when you go over the SGA limit during your trial work period or extended may be able to access period.

After your extended may be able to access period ends and your benefits stop, you can keep Medicare for an additional 93 months (about 7.75 years) as long as you pay the premiums. This is called Medicare continuation, and it is a major reason why some people can afford to work even after their SSDI benefits end.

If you are on Medicaid instead of or in addition to Medicare, the rules vary by state. Some states let you keep Medicaid while you work and earn above the SGA limit; others do not. You should contact your state Medicaid office or your local Social Security office to find out what applies to you.

When the SGA limit does not explore

There are a few situations where earning above the SGA limit does not automatically stop your benefits. The most common is if you are in your trial work period — as explained above, you can earn any amount. Another is if you are blind and working; blind beneficiaries have a higher SGA limit ($2,590 in 2024) and also have access to additional work incentives.

You also may not lose benefits if Social Security determines that your work is not substantial gainful activity for reasons specific to your disability. For example, if you have a mental health condition and you work in a sheltered workshop with significant support, Social Security may not count that as SGA even if you earn above the limit. This is rare and requires a detailed medical review.

Additionally, if you are working but your medical condition has not improved, you can request a medical improvement review to argue that you should keep your benefits despite earning above the SGA limit. This is a difficult argument to win and requires strong medical evidence, but it is an option.

Planning your return to work and reporting requirements

If you are thinking about going back to work, you should report your plans to Social Security before you start. This is not required, but it helps Social Security understand your situation and ensures that your trial work period is counted correctly from the beginning. You can report by calling your local Social Security office or through your online account.

Once you start working, you must report your earnings every month. Social Security will ask you to fill out a form (SSA-777) that asks about your work, hours, and pay. If you do not report, Social Security may stop your benefits based on the assumption that you are working above the SGA limit. If you then report later, you may have to repay benefits you received while you were not reporting.

Keep records of your pay stubs, tax documents, and any other proof of your earnings. If Social Security questions your earnings, you will need to show what you actually made. This is especially important if you are self-employed, because Social Security will want to see your business records and tax returns.

Frequently Asked Questions

Does the SGA limit include money I did not earn from work?

No. The SGA limit counts only your work earnings — wages from a job or net profit from self-employment. It does not count interest, dividends, rental income, gifts, or benefits from other programs. However, if you are on SSI instead of SSDI, unearned income does count toward your limit and can reduce your benefits.

What if I earn above the SGA limit for just one month?

During your trial work period, one month above the limit does not matter — you can earn any amount. After the trial work period ends and you are in the extended may be able to access period, one month above the limit means you lose benefits only for that month. After the extended may be able to access period ends, one month above the limit can trigger a review that may result in your benefits stopping.

Can I go back to work after my benefits stop because of SGA?

Yes. If your benefits stop because you earned above the SGA limit, you can request a new trial work period if your condition has not improved or if you want to test your work capacity again. You can also ask Social Security to review your case if your medical condition has gotten worse.

Does the SGA limit change every year?

Yes. The SGA limit is adjusted each January based on the national average wage index from the previous year. Social Security publishes the new limit in December, so you can plan ahead. The limit for blind beneficiaries is always higher than the limit for non-blind beneficiaries.

What if I am self-employed and my income varies a lot month to month?

Social Security calculates your average monthly net profit over the whole year and divides it by the number of hours you worked. This can work in your favor if you have some very high-earning months and some low-earning months, because the average may be below the SGA limit even if some individual months are above it. You should keep detailed records of your hours and income to show Social Security how the calculation works.
