SGA and SSDI in 2023: What the Earnings Limit Means for Your Benefits

If you receive Social Security Disability Insurance (SSDI) — or you're in the process of applying — one number matters more than almost any other: the Substantial Gainful Activity (SGA) threshold. In 2023, that number changed, and understanding what it means (and what it doesn't) is essential for anyone navigating work and disability benefits at the same time.

What Is SGA and Why Does It Matter for SSDI?

Substantial Gainful Activity is the SSA's measure of whether someone is working at a level that suggests they are not disabled, at least not in the way the program defines it. It's expressed as a monthly gross earnings limit.

If your earnings exceed the SGA threshold, the SSA may determine you're not disabled — regardless of your medical condition. That's true at the application stage and once you're already receiving benefits.

SGA is not the only factor in an SSDI decision, but it's one of the first things the SSA checks. It functions as a threshold test: if you clear it, your claim moves forward for medical review. If you don't, your claim can be denied outright.

The 2023 SGA Amount

For 2023, the SSA set the SGA limit at:

These figures represent gross wages, not take-home pay. Self-employment income is evaluated differently — the SSA applies additional tests related to hours worked and the value of services rendered, not just net profit.

Dollar amounts adjust annually based on changes in average wages nationwide. The 2023 figures reflected a meaningful increase over prior years, consistent with broader wage trends.

SGA During the Application Process

When someone applies for SSDI and is currently working, the SSA looks at whether earnings exceed SGA. If they do, the application is typically denied at Step 1 of the five-step sequential evaluation — before medical evidence is even reviewed.

This is significant. A claimant with a serious, well-documented condition can still be denied if they're earning above SGA at the time of application. The program is designed around the idea that disability, as the SSA defines it, involves an inability to engage in substantial work — not just the presence of a medical impairment.

There are nuances here. Unsuccessful work attempts — jobs started and stopped within a short window due to the disabling condition — may not count as SGA. The SSA applies specific rules about duration and reason for stopping work before classifying earnings as SGA.

SGA After Approval: How It Affects Current Beneficiaries 📋

Once approved, SSDI recipients can test their ability to return to work without immediately losing benefits — but the SGA limit still governs what happens longer term.

The Trial Work Period (TWP)

The SSA gives approved beneficiaries a Trial Work Period of up to 9 months (not necessarily consecutive) within a rolling 60-month window. During the TWP, you can earn any amount without affecting your SSDI payments. In 2023, a month counted toward the TWP if earnings exceeded $1,050.

After the Trial Work Period: SGA Takes Over

Once the Trial Work Period is exhausted, the SGA threshold becomes the controlling line. Earning above $1,470/month (for non-blind individuals in 2023) triggers what the SSA calls Substantial Gainful Activity, which can result in benefits being suspended or terminated.

The Extended Period of Eligibility (EPE)

After the TWP ends, beneficiaries enter a 36-month Extended Period of Eligibility. During this window, benefits can be reinstated in any month earnings fall back below SGA — without filing a new application. This provides a safety net for people whose work attempts are inconsistent or interrupted by their condition.

Variables That Shape How SGA Rules Apply to You

The SGA threshold is a fixed number, but how it interacts with your situation is anything but uniform. Several factors affect the outcome: 💡

• Employment type — W-2 wages are calculated differently than self-employment income
• Impairment-related work expenses (IRWEs) — Costs directly tied to your disability (certain medications, adaptive equipment, transportation to medical care) may be deducted from gross earnings before SGA is calculated
• Subsidies — If an employer provides special accommodations or supports that reduce your actual productivity, the SSA may discount the value of your earnings
• Whether you're blind — The program applies a higher SGA threshold for individuals meeting the SSA's statutory definition of blindness
• Stage of your claim — SGA functions differently during the application phase than it does during the Trial Work Period or Extended Period of Eligibility
• Work history and credits — SGA doesn't affect whether you've earned enough work credits to be insured for SSDI in the first place, but it does affect whether your claim advances and whether benefits continue

Profiles That Illustrate the Spectrum

Consider how differently two people in similar circumstances might be affected:

Someone working part-time at $900/month while applying for SSDI stays below the 2023 SGA limit. Their claim moves past Step 1 and into medical review. Whether they're approved depends entirely on their medical record, age, education, and prior work.

Someone else earning $1,600/month — even part-time, even with a serious impairment — would likely be denied at Step 1 based on SGA alone, unless an IRWE deduction or unsuccessful work attempt exception brings their countable earnings below the threshold.

A current SSDI recipient earning $1,200/month during their Extended Period of Eligibility remains below SGA and continues receiving full benefits. The same person, if they receive a raise pushing them to $1,500/month, crosses the SGA line — and the SSA may suspend payments.

The Piece That Remains Specific to You

The 2023 SGA threshold of $1,470 is a fixed, public rule. But how it intersects with your earnings, your work situation, your disability-related expenses, and where you are in the SSDI process — application, appeal, or already receiving benefits — is not something a general explanation can resolve. Those details determine whether the SGA limit is a barrier you're facing, a line you're comfortably under, or a threshold you've already navigated through the Trial Work Period rules. That calculation belongs to your specific circumstances.
