SSDI Income Limits in 2015: What You Could Earn While Receiving Benefits

If you were receiving SSDI in 2015 — or applying that year — one of the most important numbers you needed to know was the Substantial Gainful Activity (SGA) threshold. This figure determined how much you could earn from work without jeopardizing your benefits. Understanding how that limit worked, what it applied to, and what it didn't cover is still relevant today, whether you're researching past benefit periods or trying to understand how SSDI's work rules function over time.

What Was the SGA Limit in 2015?

In 2015, the SGA threshold for non-blind SSDI recipients was $1,090 per month. For individuals who are statutorily blind, the limit was higher — $1,820 per month.

These figures adjust annually based on changes in average wages, which is why the SGA amount looks different from year to year. The 2015 limits were a modest increase over 2014 figures ($1,070 for non-blind, $1,800 for blind recipients).

Earning above the applicable SGA threshold — through regular employment or self-employment — could trigger a review of whether you were still eligible for SSDI. Earning below it generally meant your work activity would not, on its own, disqualify you from benefits.

What SGA Actually Measures

SGA isn't simply about gross paycheck amounts. The SSA looks at countable earned income — what you actually earn after certain deductions are applied. Impairment-related work expenses (IRWEs), for example, can be subtracted before SSA evaluates whether your earnings cross the SGA line. If you paid out of pocket for equipment, medications, or services that allowed you to work despite your disability, those costs could reduce your countable income for SGA purposes.

Self-employment income is evaluated differently than wage income. The SSA examines the value of your work to the business, not just what you paid yourself, which makes self-employment calculations more complex.

The Trial Work Period: A Buffer Before SGA Rules Fully Apply

One piece of the 2015 rules that many recipients misunderstood: SGA didn't apply during the Trial Work Period (TWP). During the TWP, SSDI recipients could test their ability to return to work without losing benefits, regardless of how much they earned — as long as they continued to have a disabling condition.

In 2015, a month counted as a Trial Work Period month if earnings exceeded $780. The TWP consists of nine such months (not necessarily consecutive) within a rolling 60-month window. Only after completing the TWP did the SGA threshold become the decisive test.

After the TWP, recipients entered the Extended Period of Eligibility (EPE) — a 36-month window during which benefits could be reinstated in any month earnings fell below SGA, without a new application.

How the 2015 Limits Fit Into the Broader SSDI Framework

The SGA threshold was one layer in a multi-part system. Here's how the pieces connected in 2015:

At the application stage: SGA was used to determine whether someone was engaging in substantial work activity at the time of their application. If you were working above SGA when you applied, SSA could deny the claim at Step 1 of the sequential evaluation — before even reviewing your medical records.

After approval: SGA became the benchmark for Continuing Disability Reviews (CDRs) focused on work activity. If your earnings consistently exceeded $1,090 per month (for non-blind recipients) outside of a Trial Work Period, SSA had grounds to terminate benefits.

What SGA didn't measure: Your investment income, rental income, or other unearned income didn't count toward SGA. SSDI is not a means-tested program the way SSI is — SSDI has no asset limits and doesn't penalize recipients for savings or passive income. 💡

SSDI vs. SSI: Different Income Rules

It's worth drawing a clear distinction here. SSI (Supplemental Security Income) operates under entirely different financial rules. SSI does count most forms of income — earned and unearned — against the benefit amount, and it carries asset limits. SSDI has none of that. The only income that matters for SSDI eligibility is earned income evaluated against the SGA threshold.

If you were receiving both SSDI and SSI in 2015 — sometimes called "dual eligibility" — both sets of rules applied simultaneously, which made income tracking significantly more complicated.

Variables That Shaped Individual Outcomes in 2015

Even with a clear SGA number in place, how that limit applied in practice depended on several individual factors:

• Whether you were still in your Trial Work Period — earnings above $1,090 didn't trigger SGA review during those nine months
• Whether you had impairment-related work expenses that reduced your countable income below SGA
• Whether you were self-employed, which required SSA to use a different calculation method
• Whether a Ticket to Work assignment was in place, which could affect how work activity was reviewed
• Your specific disability — statutorily blind recipients had nearly double the SGA threshold
• What stage your case was in — applicants and current recipients faced slightly different consequences for the same earnings level

When the Numbers Change — and Why It Matters 📅

The 2015 SGA figures are no longer current. If you're researching this for a historical reason — such as an appeal involving a past benefit period, a review of a prior overpayment determination, or understanding a decision SSA made during that year — the 2015 thresholds are the correct reference point.

For any current questions about working while receiving SSDI, the applicable SGA limit is whatever SSA has set for the current calendar year. SSA publishes updated figures each fall for the following year, and those numbers can be found directly through SSA's official resources.

What doesn't change is the structure: SGA, the Trial Work Period, the Extended Period of Eligibility, and how impairment-related expenses reduce countable income all work the same way year to year. Only the dollar thresholds shift.

The 2015 rules are well-documented — what varies is how they applied to any individual recipient's work history, disability status, benefit stage, and specific earnings pattern. Those details determine whether someone's work activity in 2015 had consequences for their benefits — and that's a calculation no general guide can make.
