What counts as substantial gainful activity
Substantial gainful activity (SGA) is work that earns you a certain amount of money each month. Social Security uses this threshold to decide whether you are still disabled enough to receive SSDI payments. If your earnings cross the SGA line, Social Security will assume you can work and may stop your benefits.
The dollar amount changes every year. In 2024, the SGA threshold is $1,550 per month for most people receiving SSDI. If you are blind, the threshold is higher: $2,590 per month. These numbers are set by federal law and adjust annually based on wage trends.
The key word is earnings, not hours worked or job title. You could work 40 hours a week at minimum wage and still be under SGA, or work 10 hours a week at a high-paying job and exceed it. Social Security counts your gross income before taxes.
Key Takeaways
- SGA is a monthly earnings threshold ($1,550 in 2024 for most people, $2,590 if blind) that Social Security uses to determine if you can still work.
- If you earn more than the SGA amount in a month, Social Security may assume you are no longer disabled and can stop your SSDI payments.
- Only work earnings count toward SGA—not investment income, rental income, or benefits from other programs.
- Self-employment income counts the same way as wages, calculated as your net profit after business expenses.
- You can work below the SGA threshold and keep your full SSDI payment, but you must report your earnings to Social Security.
How Social Security measures your earnings
Social Security looks at your gross monthly earnings—the amount before taxes, deductions, or anything else comes out of your paycheck. If you are paid weekly or biweekly, Social Security will average your paychecks across the month to see if you cross the threshold.
For self-employed people, SGA is based on your net profit: the money left after you subtract legitimate business expenses. If you run a small business and your expenses are high, your net profit may stay below SGA even if your total revenue is much higher.
Work incentives can affect how your earnings are counted. If you are in a trial work period or using other work incentives that Social Security offers, the rules may be different. These programs are designed to let you test your ability to work without when ready losing benefits.
What does not count as substantial gainful activity
Investment income, rental income, interest, and dividends do not count toward SGA. If you receive money from stocks, bonds, real estate, or a savings account, Social Security does not consider this work activity.
Benefits from other programs—such as unemployment insurance, workers' compensation, or pension payments—also do not count as SGA. These are replacement income, not earnings from work.
Unpaid work does not count either. If you volunteer, help a family member without pay, or do household chores, none of that affects your SGA status. The work must produce income that you actually receive.
When Social Security checks your SGA status
Social Security does not automatically stop your benefits the moment you earn over the SGA threshold in one month. Instead, they look at a pattern. If you consistently earn more than SGA, or if your earnings show you can sustain work at that level, they will review your case.
You are required to report your earnings to Social Security. When you receive your SSDI award letter, it will explain how to report work income—usually through your online My Social Security account, by phone, or by mail. Failing to report earnings can result in overpayments that you will have to repay later.
Social Security also receives wage reports from your employer through the Social Security Administration's records. This means they often know about your earnings even if you do not report them yourself, though reporting on time is still your responsibility.
The difference between SGA and trial work period
The trial work period is a nine-month window during which you can earn any amount and keep your full SSDI payment. This is a separate rule from SGA and is designed to let you test whether you can return to work.
During your trial work period, you can earn $1,000, $5,000, or $10,000 in a month and still receive your full benefit check. The only requirement is that you report your earnings. Once your trial work period ends, the SGA threshold applies again.
After your trial work period, there is an extended may be able to access period where you can still receive benefits for months when you earn below SGA, even if other months exceed it. Understanding which phase you are in matters because the rules change.
What happens if you exceed SGA
If Social Security determines that your earnings show you can do substantial gainful activity, they will send you a notice explaining that your case is being reviewed. You will have a chance to respond and explain your situation before they make a final decision.
If they decide to stop your benefits, the termination is not when ready. There is usually a waiting period, and you have the right to request reconsideration or appeal. During an appeal, you can continue receiving benefits while your case is being reviewed.
Stopping benefits does not mean you can never receive SSDI again. If your earnings drop back below SGA later, or if your condition worsens and you can no longer work, you can request that benefits be reinstated. The process is faster if you request reinstatement within five years of when your benefits stopped.
SGA thresholds by year and category
| Year | SGA (Most People) | SGA (Blind) |
|---|---|---|
| 2024 | $1,550 | $2,590 |
| 2023 | $1,470 | $2,460 |
| 2022 | $1,350 | $2,260 |
These amounts are set by federal law and announced each October for the following year. If you are currently receiving SSDI, Social Security will use the threshold for the year in which you earned the income, not the current year's threshold.
Frequently Asked Questions
If I earn $1,600 one month, will my benefits stop when ready?
No. One month over the threshold does not automatically end your benefits. Social Security looks for a pattern showing you can sustain work at that level. If you exceed SGA in multiple months or show consistent earnings above the threshold, they will review your case and send you a notice before making any changes.
Does my spouse's income count toward my SGA?
No. Only your own work earnings count toward your SGA threshold. Your spouse's income, savings, or other resources do not affect whether you meet the SGA definition. Each person on SSDI has their own separate SGA calculation.
What if I work for a family member—does that count as SGA?
Yes, if you are paid for the work. Social Security counts wages from family members the same way as any other employer. However, Social Security may question whether the pay is reasonable for the work performed, especially if it seems unusually high or low compared to what others earn for the same job.
Can I work part-time and still receive SSDI if I stay below SGA?
Yes. You can earn up to the SGA threshold each month and keep your full SSDI payment. Many people on SSDI work part-time jobs that pay below the threshold. You must report your earnings to Social Security, but as long as you stay below SGA, your benefits continue.
If I am self-employed, how do I calculate my net profit for SGA?
Subtract your legitimate business expenses from your gross revenue. Expenses include supplies, equipment, rent for a workspace, and other costs directly related to running the business. Keep records of all expenses. If you are unsure what counts, ask Social Security or a tax professional before reporting your earnings.
