2023 SGA Limits for SSDI: What the Threshold Means and How It Affects Your Benefits

If you're receiving SSDI — or thinking about working while you receive it — the term Substantial Gainful Activity (SGA) is one of the most important numbers to know. In 2023, the SGA threshold changed, and understanding what that means can help you make smarter decisions about work, income, and your benefits.

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, in the agency's view, demonstrates they are not disabled for purposes of the program. It's expressed as a monthly earnings threshold.

If your gross earnings from work exceed the SGA limit, the SSA may determine you are no longer disabled — regardless of your medical condition. This makes SGA one of the central concepts in SSDI, both when you apply and after you're approved.

SGA applies at two key points:

• During the application process — If you're earning above SGA when you apply, the SSA will typically deny your claim at the very first step of evaluation, before even reviewing your medical records.
• After approval — Once you're receiving benefits, consistently earning above SGA (outside of protected work incentive periods) can trigger a cessation of benefits.

The 2023 SGA Amounts

The SSA adjusts SGA thresholds annually based on changes in the national average wage index. For 2023:

The threshold for individuals with statutory blindness has always been set higher by law. Both figures represent gross earnings — before taxes or deductions — which is an important distinction many people miss.

For context, the 2022 SGA limit for non-blind recipients was $1,350/month. The 2023 increase of $120 reflects the annual cost-of-living adjustment process the SSA uses to set these figures. 📊

How SGA Is Calculated — It's Not Always Straightforward

The SSA doesn't simply look at your paycheck. Several factors can affect how your earnings are counted toward SGA:

Impairment-Related Work Expenses (IRWEs): If you pay out-of-pocket for items or services that allow you to work — such as specialized equipment, medications, or transportation related to your disability — those costs can be deducted from your gross earnings before the SGA comparison is made.

Subsidies: If your employer is paying you more than the actual value of your work (a common situation in supported employment), the SSA may count only the value of what you're actually producing, not the full wage.

Self-employment: Calculating SGA for self-employed individuals is more complex. The SSA may look at your net earnings, your hours worked, or the value of your services, depending on the situation — and the analysis can differ significantly from a standard wage calculation.

These variables mean that two people earning the same gross amount can have very different SGA determinations.

SGA During the Trial Work Period

Once approved for SSDI, you're entitled to a Trial Work Period (TWP) — nine months (not necessarily consecutive) within a rolling 60-month window during which you can test your ability to work without your benefits being affected, regardless of how much you earn.

In 2023, a month counts as a Trial Work Period month if you earn more than $1,050 (a separate, lower threshold from SGA). After you've used all nine trial work months, the SSA evaluates your earnings against the SGA threshold to determine whether you've achieved substantial gainful activity.

Following the TWP, there's a 36-month window called the Extended Period of Eligibility (EPE). During the EPE, any month your earnings fall below SGA, your benefits can be reinstated without a new application — a significant protection for people whose ability to work fluctuates.

SGA at the Application Stage vs. the Maintenance Stage

It's worth being clear that SGA functions differently depending on where you are in your SSDI journey:

Applicants: Earning above SGA during the application process is a hard stop. The SSA applies this as Step 1 of its five-step sequential evaluation. If you're over the threshold, the claim is denied — the agency won't proceed to review your medical evidence at all.

Current recipients: The SGA analysis is more nuanced. Work incentive programs, the TWP, and impairment-related deductions all create buffer zones that don't exist at the application stage. A recipient earning $1,500/month may or may not be at risk depending on whether they're in a trial work period, whether IRWEs apply, and whether any subsidy adjustments are warranted.

This distinction trips up a lot of people who assume the rules work the same way in both situations. They don't. 💡

What Changes Year to Year — and What Doesn't

The SGA dollar amount adjusts annually. The underlying rules — how earnings are counted, when the TWP applies, what protections the EPE provides — are set by statute and regulation and change far less frequently.

When planning work activity around SSDI, it's worth noting the current year's threshold each January, since the SSA typically publishes updated figures at the end of the prior year.

The Part Only Your Situation Can Answer

The 2023 SGA figures are straightforward. What they mean for any individual recipient or applicant is not.

Whether your specific earnings trigger a cessation, whether your expenses qualify as IRWEs, whether you're inside or outside a trial work period, and how the SSA will treat your income from self-employment or subsidized work — all of that depends on your work history, the nature of your employment, your benefit status, and the details of your medical situation.

The threshold tells you where the line is. Where you stand relative to it is a question only your specific circumstances can answer.
