The Basic Rule: Substantial Gainful Activity

Social Security has a monthly earnings threshold called substantial gainful activity, or SGA. In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security will assume you are working at a level that means you are no longer disabled, and your benefits will stop.

This is not a hard cutoff where you lose all benefits the moment you cross it. Instead, it is the line Social Security uses to decide whether your work is substantial enough to end your disability. If you earn below this amount, you can work and keep your full SSDI payment. If you earn above it, your case will be reviewed, and your benefits will likely stop.

The SGA amount changes each year on January 1. You can find the current year's figure on the Social Security website, but the rule itself does not change: work below the threshold, keep your benefits; work above it, lose them.

Key Takeaways

  • You can earn up to $1,550 per month in 2024 and keep your full SSDI payment; the threshold is higher ($2,590) if you are blind.
  • Earnings above the threshold trigger a review that usually results in your benefits stopping, even if you have not worked for a full year.
  • Work incentives like the Trial Work Period and Extended may be able to access Period let you test your ability to work without when ready losing benefits.
  • Self-employment income counts toward the threshold the same way wages do, based on your net profit after business expenses.
  • The threshold amount increases each January; you must check the current year's figure, not assume last year's number still applies.

How Work Incentives Let You Earn More Without Losing Benefits

Social Security offers two time-limited work incentives that let you earn above the SGA threshold without losing your benefits right away. The first is the Trial Work Period, which lasts nine months. During these nine months, you can earn any amount and keep your full SSDI payment. The months do not have to be consecutive—Social Security counts only months in which you earn $1,050 or more (in 2024), so you can space them out over a longer calendar period.

After your nine Trial Work Period months end, you enter the Extended may be able to access Period, which lasts 36 months. During this time, you keep your benefits for any month in which you earn less than the SGA threshold. If you earn above it in a given month, you do not get paid that month, but your benefits do not stop permanently. Once you drop back below the threshold, your payment resumes the next month.

These incentives exist because Social Security recognizes that returning to work is a process. You may need to test whether you can actually work full-time, or you may have months where your condition flares up and you cannot work as much. The Extended may be able to access Period gives you a safety net during that transition.

What Counts as Earnings and What Does Not

Social Security counts wages from an employer, self-employment income (your net profit after business expenses), and certain other payments as earnings. Wages are straightforward: what your employer pays you. Self-employment income is trickier—you report your gross income minus ordinary and necessary business expenses, and Social Security uses that net figure to determine whether you have crossed the SGA threshold.

What does not count: Supplemental Security Income (SSI) payments, food stamps, housing information, student loans, gifts, inheritances, tax refunds, and interest or dividends from savings. Impairment Related Work Expenses (IRWE)—costs you incur specifically because of your disability to work, like special transportation or medical equipment—are also excluded from your earnings calculation.

Plan to Work Achieve Self-Support (PASS) is a more complex tool. It lets you set aside income and resources for a specific work goal without that money counting against your benefits. For example, if you are saving for vocational training or to start a business, a PASS plan can shelter that money. You must work with a Social Security representative to set one up, and it requires a written plan with specific goals and timelines.

What Happens When You Earn Above the Threshold

If you earn more than the SGA threshold in a month, Social Security does not when ready cut off your benefits. Instead, your case is flagged for medical review. A Social Security examiner will look at your medical records and work history to decide whether your earnings prove you are no longer disabled. This review can take weeks or months.

In most cases, earning above SGA for more than a few months does result in your benefits stopping. However, the outcome is not automatic. If you have a good reason for the higher earnings—for instance, you took a temporary job or had an unusually high month—you can explain that to Social Security. If your condition genuinely prevents you from sustaining that level of work, the examiner may find that you are still disabled despite the earnings.

Once your benefits stop, you do not lose your Medicare coverage when ready. You get an additional 93 months (about 7.75 years) of Medicare coverage after your SSDI payments end, even if you are working and earning above the threshold. This is called Medicare continuation, and it is one of the most valuable work incentives available.

Self-Employment and the SGA Threshold

If you are self-employed, Social Security counts your net profit—total income minus ordinary and necessary business expenses—toward the SGA threshold. You report this on your tax return, and Social Security uses that same figure. If your net profit is below $1,550 per month on average, you can continue your SSDI benefits even if your gross revenue is much higher.

Self-employment is often a good fit for people on SSDI because you can control your hours and pace. If you have a condition that makes full-time work difficult, you might be able to work part-time for yourself and stay below the threshold. Keep careful records of your expenses—equipment, supplies, rent, utilities, professional services—because these reduce your net profit and therefore your earnings count.

If you are thinking about starting a business, Social Security has a work incentive called the Plan to Achieve Self-Support (PASS) that can help. You can set aside money you earn to invest in the business without that money counting against your benefits, as long as you have a written plan with a specific timeline and goal.

Reporting Your Earnings to Social Security

You are required to report your earnings to Social Security. The exact timing depends on how you receive your benefits. If you get SSDI by direct deposit, you can report earnings online through your my Social Security account, by phone, or by mail. Social Security asks that you report within 30 days of the month in which you earned the money, though the important date is not always strictly enforced.

If you do not report earnings and Social Security discovers them later—through tax records, wage reports from your employer, or other means—you may have to repay benefits you were not supposed to receive. This is called an overpayment, and Social Security can recover it by reducing your future payments or asking you to repay it in a lump sum.

Many people worry about reporting because they fear losing benefits when ready. In reality, reporting is the safer choice. If you report and your earnings are below the threshold, nothing happens. If you report and your earnings are above it, you start the review process, which may take months. If you do not report and Social Security finds out later, you face an overpayment debt on top of losing your benefits.

How the SGA Threshold Changes Year to Year

The SGA threshold is adjusted each January based on changes in the national average wage index. In recent years, the threshold has increased by roughly $50 to $100 per year, but the exact amount varies. In 2023, the threshold was $1,470; in 2024, it rose to $1,550. You cannot assume the 2024 figure will explore in 2025.

Check the Social Security website in December or early January each year to learn the new threshold. If you are working and your earnings are close to the threshold, this annual change matters. A raise that kept you below the old threshold might push you above the new one, or a threshold increase might give you more room to earn.

The threshold for blind individuals is higher and also adjusts annually. In 2024, it is $2,590 per month. If you are blind and working, you have more room to earn before your case is reviewed.

Frequently Asked Questions

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

Yes, if your monthly earnings stay below $1,550 (in 2024). Part-time work is often the easiest way to stay under the threshold. Many people on SSDI work part-time jobs or do freelance work that lets them control their hours and stay within the earnings limit.

What if I earn above the threshold for just one month?

One month above the threshold does not automatically end your benefits. Social Security will review your case, but a single high-earning month may not be enough to stop your benefits if the examiner believes you cannot sustain that level of work. However, if you earn above the threshold for several months in a row, your benefits will almost certainly stop.

Do I lose Medicare if my SSDI benefits stop because I am working?

No. You keep Medicare for 93 months (about 7.75 years) after your SSDI payments end due to work. This is called Medicare continuation, and it is one of the strongest reasons to try working while on SSDI—you have years to test whether you can sustain employment without losing health coverage.

Can I use a Plan to Achieve Self-Support to earn more?

A PASS plan does not let you earn more per month; it lets you set aside money you earn for a specific work goal without that money counting against your benefits. For example, if you earn $2,000 per month but set aside $600 for vocational training under a PASS plan, only $1,400 counts toward the SGA threshold. You must work with Social Security to create a written plan with specific goals and timelines.

What if my employer pays me in cash and I do not report it?

Social Security can discover unreported cash income through tax records, wage reports, or other means. If you do not report and they find out, you will owe back the benefits you should not have received, plus you will lose your benefits. Reporting is always the safer choice, even if you are worried about losing benefits.
