What the 2017 SSDI income limits were

In 2017, Social Security set two income thresholds that mattered for SSDI: the Substantial Gainful Activity (SGA) limit and the Trial Work Period (TWP) threshold. The SGA limit—the amount you could earn before Social Security considered you no longer disabled—was $1,170 per month for non-blind beneficiaries and $1,950 per month for blind beneficiaries. These numbers changed every year based on national wage averages.

The Trial Work Period allowed you to test your ability to work without losing benefits. During the TWP, you could earn any amount and still receive your full SSDI payment each month you worked. The TWP lasted nine months (not necessarily consecutive) within a rolling 60-month window. After the TWP ended, the SGA limit kicked in: if you earned more than $1,170 per month, Social Security would review whether you were still disabled.

These limits applied only to your work earnings. Other income—such as pensions, investments, or rental income—did not count toward SGA and did not affect your SSDI payment amount. SSDI itself has no income limit based on how much money you have in the bank or what you own.

Key Takeaways

  • The 2017 SGA limit was $1,170 per month for non-blind beneficiaries; blind beneficiaries had a higher limit of $1,950 per month.
  • During your nine-month Trial Work Period, you could earn any amount without losing your SSDI payment.
  • After the Trial Work Period ended, earning more than the SGA limit triggered a medical review to determine if you were still disabled.
  • Non-work income such as pensions or investments did not count toward the SGA limit and did not reduce your SSDI payment.

How the Trial Work Period protected your benefits

The Trial Work Period was designed to let you test whether you could return to work without the fear of when ready losing your benefits. During those nine months, Social Security paid you your full SSDI benefit regardless of how much you earned. This gave you a real chance to see if work was sustainable for you—whether your condition would worsen, whether you could manage the schedule, or whether the job was a good fit.

The nine months did not have to be consecutive. If you worked in January, took a break in February, and worked again in March, both months counted toward your nine-month total. The entire 60-month window gave you flexibility: you could spread out your work months over five years if you needed to.

Once you used up all nine months of your Trial Work Period, the rules changed. At that point, the SGA limit became the threshold. If you earned $1,170 or more in any month, Social Security would begin a medical review. That review determined whether your condition had improved enough that you were no longer disabled. You were not automatically cut off—but you were no longer protected from a review based on your earnings alone.

What happened if you earned above the SGA limit

Earning more than $1,170 per month in 2017 did not automatically end your SSDI. Instead, it triggered what Social Security called a medical continuing disability review. Social Security would contact you and ask for updated medical evidence about your condition. They wanted to know whether you had improved, whether your treatment had changed, or whether you were managing your disability differently than before.

The outcome depended on the evidence. If your medical records showed that your condition had improved significantly—for example, if surgery had been successful or medication had become much more effective—Social Security might decide you were no longer disabled and stop your benefits. If your records showed your condition was stable and you were working despite your limitations, your benefits could continue. Some beneficiaries worked above the SGA limit for years while their benefits remained active.

The key was that earning above SGA meant Social Security would look more closely. It was not a penalty, but it was a signal that triggered review. This is why understanding the SGA limit mattered: crossing it did not end your benefits, but it did mean you should be prepared to provide medical documentation if Social Security asked.

The difference between SGA and other work incentives

SSDI included other work rules beyond the SGA limit that gave you more flexibility. The Plan to Achieve Self-Support (PASS) allowed you to set aside income and resources for a specific work goal—such as education, training, or starting a business—without that money counting against you. A PASS was a written plan you created with a Social Security work incentive specialist.

The Impairment Related Work Expenses (IRWE) deduction let you subtract the cost of items or services you needed because of your disability in order to work. If you paid for a personal assistant, specialized transportation, or medical equipment required for your job, those costs could be deducted from your earnings before Social Security calculated whether you had crossed the SGA limit.

These tools existed because Social Security recognized that people with disabilities often faced extra costs to work. The SGA limit was a baseline threshold, but it was not the only way Social Security measured whether you could work. If you were working in 2017 and earning close to or above $1,170 per month, a work incentive specialist could help you understand which of these tools might reduce your countable earnings.

Why the SGA limit changed every year

Social Security adjusted the SGA limit annually based on changes in the national average wage index. The index measured what American workers earned on average across the country. When average wages rose, the SGA limit rose with it. This meant the threshold moved slightly every January.

The reason for this adjustment was fairness. If the SGA limit stayed at the same dollar amount year after year while wages climbed, it would become easier and easier for beneficiaries to cross the threshold straightforward because of inflation—not because they had actually improved. By tying the limit to national wages, Social Security kept the standard consistent: the SGA limit represented roughly the same level of work capacity regardless of the year.

For 2017 specifically, the SGA limit of $1,170 for non-blind beneficiaries represented the national wage average for that year. If you were tracking your own earnings against this limit, you needed to know the 2017 figure. If you were working in a different year, the limit would be different—usually higher, because wages generally rise over time.

How to find the SGA limit for other years

If you were working in 2017 but also want to understand the limits for years before or after, Social Security published the SGA limit for every year on its official website. The limit appeared in the "Red Book," Social Security's handbook for beneficiaries, and in annual notices that went out to all SSDI recipients.

You could also contact Social Security directly by calling 1-800-772-1213 to ask what the SGA limit was for any specific year. A representative could tell you the limit and explain how it applied to your situation. If you were working and wanted to understand whether your earnings would trigger a review, Social Security could also connect you with a work incentive planning specialist who could review your specific numbers.

Frequently Asked Questions

If I earned $1,200 a month in 2017, would I lose my SSDI?

Not automatically. Earning above the $1,170 SGA limit would trigger a medical review, but Social Security would not stop your benefits without examining your medical records. If your condition had not improved, your benefits could continue even though you were working above the limit. The review was the consequence, not when ready termination.

Did the SGA limit explore to money I received from investments or a pension?

No. The SGA limit applied only to work earnings—money you made from a job or self-employment. Pensions, investment income, rental income, and other non-work money did not count toward the SGA limit and did not affect your SSDI payment amount.

Could I use the Trial Work Period months across different jobs?

Yes. The nine months of your Trial Work Period counted any month in which you earned money from work, regardless of whether you had the same job or switched employers. If you worked part-time at one job in January and switched to a different job in February, both months counted toward your nine-month total.

What was the difference between the SGA limit for blind and non-blind beneficiaries in 2017?

Blind beneficiaries had a higher SGA limit of $1,950 per month, compared to $1,170 for non-blind beneficiaries. Social Security recognized that blind individuals often faced higher costs related to work and set a higher earnings threshold before triggering a medical review.

If I earned above SGA in 2017, when would Social Security contact me?

Social Security typically contacted beneficiaries within a few months of learning about earnings above the SGA limit. They would request updated medical evidence and explain that a continuing disability review was underway. The timeline varied depending on how Social Security learned about your earnings and how quickly they processed the information.
