The 2021 Substantial Gainful Activity threshold

In 2021, Social Security set the Substantial Gainful Activity (SGA) limit at $1,310 per month for non-blind workers and $2,190 per month for blind workers. If you earned more than that amount in a month, Social Security could find that you were no longer disabled and stop your benefits — even if you had been receiving SSDI for years.

The SGA limit changes every year because it is tied to the national average wage index. The 2021 figure was higher than 2020 ($1,260 for non-blind workers) because average wages had risen. Social Security announces the new limit each October for the following calendar year, so the 2021 limit was set in October 2020.

The limit applied to your countable earnings — wages you received for work, minus impairment-related work expenses (IRWE) and other deductions Social Security allowed. It did not matter whether you worked one month or twelve; if any single month crossed the threshold, that month counted as SGA.

Key Takeaways

  • The 2021 SGA limit was $1,310 per month for non-blind workers; earning more than that in any month could trigger a work incentive review or benefit suspension.
  • Blind workers had a higher limit of $2,190 per month in 2021, reflecting different work capacity assumptions.
  • The limit applied only to countable earnings after deductions like impairment-related work expenses were subtracted.
  • Crossing the SGA limit did not automatically end benefits; it triggered a review, but work incentives like Trial Work Period could protect your benefits during that time.

How the 2021 limit connected to your Trial Work Period

If you were in your Trial Work Period (TWP), the SGA limit did not matter. During the nine-month TWP, you could earn any amount without affecting your benefits. The TWP was designed to let you test your ability to work without the risk of losing SSDI when ready.

Once your TWP ended, the SGA limit became the boundary. If you earned $1,310 or more in a month after your TWP, Social Security would count that month as a month of SGA. After nine months of SGA in a 60-month window, your benefits would stop — though you would enter the Extended may be able to access Period, which gave you three more years to use your work incentives.

Many people in 2021 did not realize they were still in their TWP or had already used it up. Checking your Social Security statement or calling 1-800-772-1213 could tell you where you stood in the timeline.

What happened if you earned over the limit in 2021

Earning more than $1,310 in a single month did not automatically stop your benefits that month. Instead, Social Security reviewed your case to determine whether you were still disabled. The review could take weeks or months.

During the review, you kept receiving your regular SSDI payment. If Social Security concluded you had returned to work at the SGA level, they would send you a notice explaining the decision and your right to appeal. The appeal process could take several months, during which you continued to receive benefits.

If you disagreed with the decision, you could request reconsideration, then a hearing before an Administrative Law Judge. Many people won their cases at the hearing level, especially if they could show that the high-earning month was unusual or that their impairment still limited their ability to work consistently.

The difference between SGA and the Trial Work Period earnings test

The SGA limit and the TWP operated on different rules, and confusing them cost people benefits. During your TWP, you could earn $1,000, $2,000, or $5,000 in a month with no penalty. The TWP counted only months in which you earned $200 or more (in 2021); months below that did not count toward your nine-month limit.

After your TWP ended, the SGA limit took over. Now earning $1,310 or more triggered the SGA review process. The key difference: the TWP protected you from any review, while the SGA limit put you under review but did not automatically end benefits.

Many people in 2021 thought they had to stay under $1,310 during their TWP. That was wrong and cost them money. If you were in your TWP, you could have earned more without penalty — the whole point of the TWP was to let you test work without risk.

How impairment-related work expenses reduced your countable earnings in 2021

You could subtract impairment-related work expenses (IRWE) from your gross earnings before Social Security compared your income to the SGA limit. An IRWE was a cost you paid because of your disability and that you needed to work.

Common examples in 2021 included: a personal assistant to help you at work, specialized transportation, medication or medical equipment you used only for work, therapy sessions scheduled around your work hours, or modifications to your workplace or tools. The expense had to be reasonable and directly tied to your ability to work.

If you earned $1,500 in a month but paid $300 for a personal care attendant you needed at your job, your countable earnings were $1,200 — below the SGA limit. You had to report the IRWE to Social Security and provide receipts or invoices. Social Security did not automatically know about these expenses; you had to tell them.

Why the 2021 limit matters now

The 2021 SGA limit no longer applies — 2024 and 2025 have their own thresholds. But understanding how the 2021 limit worked helps you understand how the current limit works. The rules have not changed; only the dollar amount updates each year.

If you are reviewing old notices or appeal decisions from 2021, knowing the 2021 threshold helps you understand why Social Security made the decision they did. If you are calculating whether you could have worked more during 2021 without triggering a review, the $1,310 figure (or $2,190 for blind workers) is the number that mattered.

Social Security's website publishes historical SGA limits going back decades. If you need to understand a decision from any year, you can find the exact limit that applied and work backward from there.

Frequently Asked Questions

If I earned $1,500 in one month in 2021, did my benefits stop when ready?

No. Earning over the SGA limit triggered a review, but your benefits continued while Social Security investigated. The review could take weeks or months. Your benefits would only stop if Social Security concluded you had returned to work at the SGA level and you did not appeal or win your appeal.

Did the 2021 SGA limit explore if I was still in my Trial Work Period?

No. The SGA limit did not explore during your TWP. You could earn any amount during those nine months without triggering a review. The SGA limit only mattered after your TWP ended.

Could I reduce my countable earnings below $1,310 by reporting work expenses?

Yes, if those expenses were impairment-related work expenses. You had to report them to Social Security with receipts. Common examples were personal care attendants, specialized transportation, or workplace modifications. Social Security did not automatically know about these costs.

What was the SGA limit for blind workers in 2021?

The 2021 SGA limit for blind workers was $2,190 per month, significantly higher than the $1,310 limit for non-blind workers. Social Security assumes blind workers may need more time and support to reach full work capacity.

If I earned over the SGA limit in 2021, can I appeal that decision now?

It depends on how long ago the decision was made and whether you already appealed. If Social Security made a formal information and you did not appeal within 60 days, the time to appeal has likely passed. Contact Social Security or a disability advocate to review your specific case and notice.
