Understanding SGA: The Earning Limit That Could Make or Break Your SSDI Claim

When applying for Social Security Disability Insurance (SSDI), one term can feel like a dealbreaker before you even start: Substantial Gainful Activity, or SGA. But don’t panic—understanding SGA doesn’t have to be overwhelming. In fact, once you break it down, it’s one of the most important (and manageable) pieces of your SSDI puzzle.

This guide is here to help you navigate SGA with confidence—so you can start your disability claim with clarity and avoid common missteps that could delay or deny your benefits.

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 meaningful physical or mental activity, and “gainful” means work that’s usually done for pay—even if you don’t make a profit. 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—to decide if someone’s work activity is too much to be considered disabled.

If your earnings exceed the monthly SGA limit, the SSA may conclude you’re not eligible for SSDI because you’re capable of working at a meaningful level.

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 this amount from working, the SSA is likely to deny your SSDI application—regardless of your diagnosis—unless you can prove special circumstances (like subsidies, unsuccessful work attempts, or unpaid assistance on the job).

💡 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.

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 might sound like legal jargon, but it’s really just about how much you earn from working—and whether the SSA sees that as proof you’re still capable of full-time employment. Before you apply for SSDI, understanding the SGA rules can make a major difference between an approval and a denial. Know your numbers, document your limits, and when in doubt—ask for help.
