Social Security's work rules are different for individuals currently receiving SSDI and those receiving SSI. (For a discussion of how much you can work when first applying for benefits, see our section on working and eligibility for Social Security disability.)
Generally, SSDI recipients can't do what's considered "substantial gainful activity" (SGA) and continue to receive disability benefits. In a nutshell, doing SGA means you're working and making more than $1,310 per month in 2021 (or $2,190 if you're blind). But to encourage SSDI recipients to go back to work, Social Security has created some exceptions to this rule. SSDI recipients are entitled to a "trial work period" during which they can make more than the SGA amount without losing benefits.
For the nine-month trial work period, SSDI recipients are entitled to test their ability to work and continue to receive full benefits regardless of whether they make more than the SGA amount. For 2021, the Social Security Administration (SSA) considers any month where a person has a monthly income of more than $940 to be a trial work month. If you're self-employed, any month where you work more than 80 hours can also be considered a trial work month.
Once you have completed the nine-month trial work period (the months do not need to be consecutive), you can still receive SSDI for any month where your earnings fall below the SGA level, for a period of 36 months. This three-year period is called the "extended period of eligibility." In other words, if you earn less than $1,310 in any month during this period, you will get benefits, but if you earn more than $1,310 in any month, you won't get disability benefits for that month (after a three-month grace period).
Following your trial work period, if Social Security has stopped your SSDI payments because your income is "substantial," the agency gives you five years during which your benefits can be reinstated if you again stop working because of your disability. During this five-year period, called the "expedited reinstatement period," the SSA will not require you to file a new disability application to get benefits.
For more information, see our article on the trial work period, the extended period of eligibility, and expedited reinstatement.
You can begin to work and continue to receive SSI benefits as long as your wages and other resources don't exceed the SSA's income limit for SSI; but your monthly benefit amount will be reduced in proportion to your income.
Here's how the SSA reduces your income. Both the federal benefit amount and the SSI countable income limit are $794 (in 2021). The SSA will reduce your benefit by the amount of your "countable income." Fortunately, not all of your income is countable income.
If your only income is from your job, the SSA does not include the first $85 you earn toward your countable income. After taking the $85 adjustment off of your income, the SSA will deduct, from your monthly benefits, 50 cents for every dollar you earn. For example, if you earn $1,000 a month from working, you have $457.50 of countable income.
Your monthly SSI benefit amount would be reduced by $457.50. (You can earn up to about $1,675 a month, if you have no other income, before your SSI benefit would be reduced to zero.)
Your monthly benefit amount is also affected by the amount your state adds to the federal SSI payment, if any. For more information, see our article on how much SSI pays.
If your SSI payments stop because you earn too much money (that is, if your countable income is over $794 per month), but you are then forced to quit work because of your disability, the SSA will reinstate your benefits without the need for a new application for a period of five years.

If, because of your disability, you have certain work-related expenses that a non-disabled person wouldn't have, the SSA will deduct these costs from your monthly earnings when calculating your benefits. Examples of qualifying expenses include special transportation needs or counseling services. These are called impairment-related work expenses, or IRWE.
Both SSI and SSDI recipients must report to the SSA:
You must also report the amount of your monthly wages (if any) to the SSA. If you report your wages by telephone, it must be done by the 6th of the next month; if you mail or bring in your paystub to your local SSA, it must be done by the 10th of the next month. SSDI and SSI recipients can now report wages online using their Social Security account, and SSI recipients can now also report wages with a smartphone app. Social Security's website has more information on telephone wage reporting and online wage reporting.
Also, see our section on reporting changes to Social Security to find out what other changes you may need to report.
Keep in mind that the mere fact that you're working, even if you are making slightly less than $1,310 per month, may influence whether a disability claims examiner or a disability judge believes you are disabled, especially if you're working more than 15 or 20 hours a week. For this reason, many disability lawyers and representatives will advise their clients not to work while their case is pending. For more information, see our article on whether you have to quit work when applying for disability benefits.
