What the 2018 SGA limit was and how it affected your work
In 2018, the Substantial Gainful Activity (SGA) limit for SSDI was $1,180 per month. This is the amount of monthly earnings at which Social Security considers you to be working at a substantial level. If you earned more than $1,180 in a month, Social Security could find that you were no longer disabled and reduce or stop your benefits, even if you reported the income.
The SGA limit changes every year because it is tied to the national average wage index. The 2018 figure of $1,180 applied to most workers under full retirement age. If you were blind, the limit was higher — $1,970 per month — because Social Security has a separate earnings rule for blind beneficiaries.
The key point is that this limit was about your actual earnings, not your work capacity. You could work part-time, earn less than $1,180, and keep your full SSDI payment. You could also earn more than $1,180 in some months and less in others, as long as you did not consistently exceed the limit.
Key Takeaways
- The 2018 SGA limit was $1,180 per month for most SSDI beneficiaries, and $1,970 per month if you were blind.
- Earning more than the SGA limit in a month does not automatically stop your benefits, but it signals to Social Security that you may no longer be disabled.
- The SGA limit changes every January based on wage data from the previous year, so the 2019 limit and beyond would have been different.
- Work incentives like the Trial Work Period and Extended may be able to access Period allowed you to test your ability to work without losing benefits when ready.
How Social Security used the SGA limit to review your case
Social Security did not automatically stop your benefits the moment you earned $1,180 in a single month. Instead, the SGA limit was a threshold that triggered a review of your medical condition and work history. If you consistently earned above the limit, Social Security would contact you and ask for information about your work, your medical status, and whether your condition had improved.
During this review, Social Security looked at whether you were actually performing substantial work — not just earning above the threshold. The agency considered the type of work, the hours you worked, the skills required, and whether you were doing the job at the same level as someone without a disability. A high-paying job you could do only a few hours per week might not count as substantial, while a full-time job at minimum wage clearly would.
If Social Security determined that you were performing substantial gainful activity, it would send you a notice explaining that your benefits would end. You would have the right to request reconsideration or appeal that decision.
The Trial Work Period and how it protected your earnings in 2018
One of the most important work incentives available in 2018 was the Trial Work Period (TWP). This allowed you to work and earn any amount of money for nine months without affecting your SSDI benefits, as long as you reported your work to Social Security.
The nine months did not have to be consecutive. Social Security counted any month in which you earned $200 or more as a trial work month. Once you used nine trial work months, the TWP ended, and the SGA limit of $1,180 applied again. This gave you a protected window to test whether you could sustain work without the when ready risk of losing benefits.
Many people in 2018 used the TWP to return to work gradually, starting with part-time jobs or self-employment. The key was reporting your earnings to Social Security each month so the agency could track your trial work months accurately.
Extended may be able to access Period after your Trial Work Period ended
After you exhausted your nine trial work months, Social Security did not when ready cut off your benefits if you earned above the SGA limit. Instead, you entered the Extended may be able to access Period (EEP), which lasted 36 months. During the EEP, you could still receive a partial or full SSDI payment in any month you earned less than the SGA limit, even though you had already used your trial work period.
This meant that in 2018, if you were working but had months where your earnings dipped below $1,180, you would still get paid for those months. The EEP was designed to cushion the transition from full-time benefits to full-time work, recognizing that work income can be uneven, especially when you are managing a disability.
Once the EEP ended, the SGA limit still applied, but you lost the protection of receiving partial payments in low-earning months. At that point, if you earned $1,180 or more in a month, your benefits for that month would be withheld.
Impairment Related Work Expenses and Plan to Achieve Self-Support
In 2018, two other work incentives could help you earn more while keeping your benefits. Impairment Related Work Expenses (IRWE) allowed you to deduct certain costs directly related to your disability from your earnings before Social Security calculated whether you exceeded the SGA limit. If you paid for a personal assistant, specialized transportation, medical equipment, or therapy needed to work, those costs could be subtracted from your gross earnings.
The Plan to Achieve Self-Support (PASS) was a more complex tool that let you set aside income and resources for a specific work goal — like education, training, or starting a business — without those funds counting against your benefits. A PASS had to be in writing and approved by Social Security before you started setting money aside, but it could significantly extend your ability to work and save without losing SSDI.
Both IRWE and PASS required documentation and ongoing reporting, but they were valuable for people who wanted to work toward independence while keeping their safety net in place.
What happened if you earned above SGA in 2018
If you earned more than $1,180 per month consistently in 2018 and were not in your trial work period, Social Security would send you a letter asking about your work and medical status. You would have the chance to explain your situation and provide medical evidence if your condition had not improved. Social Security would review your case file and decide whether to continue, reduce, or stop your benefits.
The process was not automatic or when ready. You would receive written notice of any decision, and you had the right to request reconsideration within 60 days. If Social Security stopped your benefits, you could appeal to an Administrative Law Judge, and during the appeal, your benefits would usually continue while the case was pending.
It was important to report your earnings honestly and on time. Failing to report work income could result in an overpayment — money Social Security said you owed back — even if you did not realize you had exceeded the limit.
How the 2018 SGA limit compared to other years
The SGA limit changes every year. In 2017, it was $1,170 per month. In 2019, it rose to $1,220 per month. The increase from year to year is usually small — typically between $10 and $50 — but over time, the limit has climbed significantly. In 2010, the SGA limit was $1,000 per month, so by 2018 it had grown by 18 percent.
If you were reviewing your 2018 earnings history now, it is important to know what the limit was that year specifically. Social Security applies the SGA limit that was in effect during the year you earned the money, not the current year's limit. So if you are looking back at 2018 work income, you would use the $1,180 figure, not today's limit.
Frequently Asked Questions
If I earned $1,200 in one month in 2018, did my benefits stop when ready?
No. Earning above the SGA limit in a single month did not automatically stop your benefits. Social Security would review your case to determine whether you were performing substantial gainful activity overall. If you were in your trial work period, that month would count as a trial work month, but your benefits would continue.
What if I was self-employed in 2018 — how did the SGA limit explore?
Self-employment earnings counted toward the SGA limit the same way as wages from an employer. Social Security looked at your net profit (income minus business expenses) to determine whether you exceeded $1,180 per month. Self-employed people often benefited from IRWE deductions for business-related disability costs.
Could I have worked part-time and kept my full SSDI payment in 2018?
Yes, as long as you earned less than $1,180 per month and were not in your extended may be able to access period or past it. Many SSDI beneficiaries worked part-time jobs that paid under the SGA limit and received their full monthly benefit plus their wages.
If I'm looking back at my 2018 earnings now, which SGA limit should I use?
Use the 2018 SGA limit of $1,180 per month. Social Security applies the limit that was in effect during the year you earned the money, not the current year's limit. This matters if you are reviewing your work history or disputing an overpayment from that year.
Did the SGA limit explore differently if I was over 65 in 2018?
The SGA limit applied the same way regardless of age while you were receiving SSDI. However, once you reached full retirement age, your SSDI benefits converted to retirement benefits, and a different earnings rule (the retirement earnings test) applied instead. The SGA limit of $1,180 was for people under full retirement age who were still on the SSDI rolls.
