Understanding SGA: The Earning Limit That starts or ends Your SSDI Claim

Before you even fill out your first SSDI form, you may come across a phrase that makes you pause: Substantial Gainful Activity. What does it really mean — and why does it matter so much? This one rule is central to how the Social Security Administration decides whether someone qualifies as “disabled” under federal standards. By the end of this guide, you’ll have a clearer picture of how SGA works—and how to start your disability claim feeling informed and ready to take the next step.

What Is Substantial Gainful Activity (SGA)

Substantial Gainful Activity (SGA) is how the Social Security Administration (SSA) measures whether your level of work activity disqualifies you from receiving disability benefits. In simple terms: if you’re working and earning above a certain monthly amount, the SSA may determine you’re not disabled under their rules—even if your medical condition is serious.

SGA Means Two Things:

  • Substantial = Your work involves significant physical or mental activity.

  • Gainful = You’re getting paid, or it’s work you’d typically be paid for.

Where Is SGA Defined in the Law?

The rules about Substantial Gainful Activity (SGA) come straight from federal law. The Social Security Administration (SSA) follows the definition written in 20 C.F.R. § 404.1572, a section of the Code of Federal Regulations. It says that “substantial” work involves significant physical or mental activity, and “gainful” means work that’s usually done for pay. This legal definition is also supported by the Social Security Act, Section 223(d), which explains who qualifies as disabled. SSA staff use these official rules—along with their internal policy manual, called POMS and the official Blue Book listings—to decide if someone’s work activity is too much to be considered disabled.

If your monthly earnings are higher than the SGA limit set by the SSA, your work may be considered substantial enough that you don’t meet the agency’s definition of disability.

What’s the Monthly SGA Limit in 2025?

According to SSA.gov, the SGA threshold for 2025 is:

  • $1,620 per month for non-blind individuals

  • $2,700 per month for individuals who are statutorily blind

If you earn more than the monthly SGA limit from working, the SSA generally does not consider you disabled under its rules. However, certain exceptions—such as subsidies, unsuccessful work attempts, or unpaid help on the job—may affect how your earnings are evaluated.

💡 Important: Income from investments or gifts doesn’t count toward SGA. The focus is on income from work.

Why SGA Matters Before You Apply

Many applicants don’t realize their job—even part-time—can block their SSDI approval. Here’s why understanding SGA early on is crucial:

  • 💼 You might be working too much to qualify

  • ❌ Earnings over the SGA limit could trigger a denial—even with solid medical evidence

  • 📉 Reducing hours or documenting employer accommodations may help clarify your eligibility

Starting your disability claim while earning above the SGA limit is a common but avoidable mistake. It will save you time if you review your earnings, hours, and accommodations before you apply for disability.

Can You Still Work and Get Disability?

Yes—but it depends. The SSA allows limited work under certain programs:

1. Trial Work Period (TWP)

After approval, you can test working again for 9 months (not necessarily consecutive) without losing benefits—regardless of how much you earn.

2. Subsidized Employment

If your employer is paying you more than your work is objectively worth due to kindness, accommodations, or family relationship, that income may be reduced for SGA calculations.

3. Unsuccessful Work Attempt (UWA)

If you tried to work but your condition forced you to stop within 6 months, that income might not count against you.

Tips for Navigating SGA Successfully

Understanding SGA isn’t just about avoiding denial—it’s about planning smartly from the start:

  • 📂 Document everything: If you work with help, get it in writing.

  • 📅 Track your income monthly, not yearly.

  • 📉 Don’t guess—calculate: SSA uses gross earnings before taxes.

  • 💬 Consult a disability advocate or attorney: They can help present your work activity clearly.

Summary: Know the SGA Line Before You Cross It

Substantial Gainful Activity (SGA) might sound like legal jargon, but it simply refers to how much you earn from working—and how the Social Security Administration (SSA) evaluates whether that work is considered substantial under its rules. Understanding SGA before you apply for Social Security Disability Insurance (SSDI) can help you approach your claim with a better understanding and realistic expectations. Know the current SGA limits, keep records of your work activity, and reach out to the SSA or a qualified professional if you have questions.
