Substantial Gainful Activity and SSI Limits for 2026

Every January the Social Security Administration recalculates the numbers that govern whether your adult child keeps their benefits or loses them. Miss a threshold by a few dollars and you can trigger an overpayment notice, a benefit suspension, or worse — a full denial at the age-18 redetermination. Here are the 2026 figures, verified against SSA's published schedules.

2026 Substantial Gainful Activity Limits

Substantial Gainful Activity (SGA) is the earnings level the SSA uses in the initial disability test and, for Social Security disability benefits, in certain work reviews. For 2026:

  • Non-blind SGA: $1,690 per month in gross earnings
  • Blind SGA: $2,830 per month for Social Security disability benefits; the blind SGA does not apply to SSI

For a new non-blind SSI or SSDI claim, earnings above the applicable SGA threshold can lead SSA to find that the applicant is not disabled. For an SSDI or DAC beneficiary, SGA can affect eligibility after the trial work period; SSI recipients who work are generally evaluated under SSI income-counting and work-incentive rules instead.

The SGA figure matters most during the age-18 redetermination. The SSA evaluates your child under the adult disability standard, which asks whether they can engage in any substantial gainful activity — not the childhood standard of "marked and severe functional limitations."

SSI Federal Benefit Rate

The 2026 SSI federal benefit rate reflects a 2.8% cost-of-living adjustment from 2025:

  • Individual: $994 per month
  • Eligible couple: $1,491 per month

Arkansas does not add a state supplement to SSI, so $994 is the maximum monthly cash benefit. If your child lives in someone else's household and receives both food and shelter, the SSA applies the one-third reduction rule, cutting the payment to about $663.

Resource Limits

The SSI resource limit has not changed in decades:

  • Individual: $2,000 in countable assets
  • Couple: $3,000

Countable resources include bank accounts, cash, stocks, and property beyond a primary home and one vehicle. Exceeding the limit by even $1 in any month can make the individual ineligible for SSI — and in Arkansas, losing SSI can end SSI-linked Medicaid unless another Medicaid pathway applies.

The critical workaround is an ABLE account. The first $100,000 in an ABLE account is completely excluded from the SSI resource count, and Medicaid eligibility is preserved regardless of the total balance.

Trial Work Period and Earned Income Thresholds

For SSDI and DAC beneficiaries who want to test their ability to work:

  • Trial Work Period (TWP) threshold: $1,210 per month — earning above this in any month counts as a trial work month
  • Nine trial work months are allowed within a rolling 60-month window before benefits are reevaluated
  • Student Earned Income Exclusion (SEIE): Up to $2,410 per month and $9,730 per year for students under 22 enrolled in school

The SEIE is one of the most generous SSI work incentives available. It allows a student with a disability to earn substantial wages while the SSA excludes those earnings entirely from the SSI income calculation. Once the student graduates or turns 22, the exclusion disappears — another reason the transition cliff hits hard.

How These Numbers Work Together

A practical example: your 19-year-old receives $994 in SSI. They start a part-time job earning $800 per month. Under SSI income rules, the SSA excludes the first $20 (general exclusion) and the first $65 (earned income exclusion), then counts half the remainder. Their countable income is ($800 - $20 - $65) / 2 = $357.50. Their SSI payment drops to $994 - $357.50 = $636.50. They still qualify for Medicaid. They keep more total income ($1,436.50) than they would without working.

If that same person has approved Impairment-Related Work Expenses — transportation to a job site, medication required for work — those costs are deducted before the SSA calculates countable income, protecting even more of the SSI check.

What This Means for Arkansas Families

These thresholds affect different parts of the benefits picture. The $2,000 resource limit determines SSI eligibility and can affect SSI-linked Medicaid. The SGA limit is mainly an initial disability-eligibility test for SSI and an ongoing work test for SSDI/DAC after the trial work period. The TWP threshold determines when trial work months start counting for SSDI and DAC beneficiaries.

The Arkansas SSI at 18 & Adult Disability Benefits Guide consolidates these thresholds with Arkansas-specific Medicaid rules, CES waiver coordination, and monthly reporting deadlines into a single tracker — so you know exactly which numbers to watch and when to report.
