The Earned Income Reduction Formula

SSI does not vanish the moment a disabled adult earns a paycheck. Social Security reduces the SSI payment gradually using a formula that always leaves the individual with more total income than they had on SSI alone.

The 2026 calculation:

1. Take monthly gross earned income
2. Subtract $20 (general income exclusion)
3. Subtract $65 (earned income exclusion)
4. Divide the remainder by 2

The result is the countable earned income. Subtract that from the $994 federal benefit rate to get the reduced SSI payment.

Example: A young adult in Arizona earns $900/month at a supported employment job.

• $900 − $20 − $65 = $815
• $815 ÷ 2 = $407.50 countable income
• $994 − $407.50 = $586.50 SSI payment
• Total monthly income: $900 + $586.50 = $1,486.50

That's $492.50 more per month than the $994 SSI-only check. Working always pays more than not working under this formula.

Student Earned Income Exclusion (SEIE)

For students under age 22 who regularly attend school, the SEIE provides an even larger cushion. In 2026, students can exclude up to $2,410/month and $9,730/year from SSI earned income calculations entirely — before the regular formula even applies.

Using the same $900/month example for a 19-year-old community college student:

• SEIE excludes the entire $900 (under the $2,410 monthly cap)
• Countable earned income: $0
• SSI payment stays at the full $994
• Total monthly income: $900 + $994 = $1,894

The SEIE applies to students under age 22 who meet SSA's definition of regularly attending school, college, university, or vocational/technical training; attendance requirements can vary by program and disability accommodation. Confirm the current requirement with SSA, especially for a home-schooling arrangement.

Section 1619(b) — AHCCCS Protection

This is the rule families worry about most: what happens to Medicaid when earnings push the SSI payment to zero?

Section 1619(b) keeps AHCCCS Medicaid active even after the SSI cash payment reaches $0 due to earnings, as long as annual earnings stay at or below Arizona's state threshold. For 2026, that threshold is $59,182/year (approximately $4,932/month).

The individual must still meet the original disability criteria and must need Medicaid to continue working (which is presumed if they had Medicaid before their earnings increased). As long as earnings stay at or below the threshold, AHCCCS coverage can continue. Ask AHCCCS and DDD how this interacts with DDD health-plan coverage and ALTCS services.

This means a disabled young adult in Arizona may keep AHCCCS Medicaid after earnings eliminate the SSI cash payment. Do not assume that Section 1619(b) automatically preserves every DDD or ALTCS service; confirm the effect on those services with AHCCCS and DDD.

How Work Affects ALTCS and DDD

Earned income interacts differently with ALTCS than with SSI:

• ALTCS income cap is $2,982/month gross income (2026). If combined SSI + earned income + any other income exceeds this, ALTCS eligibility requires a Miller Trust to route the excess.
• DDD eligibility has no income test. Once an individual is determined eligible for DDD services based on their diagnosis and functional limitations, earnings do not affect that eligibility.
• PPCG hours — if a parent is the paid caregiver and the young adult is also working, ask DDD or the health plan how the authorized services and non-overlap rules apply. Do not bill overlapping periods.

Getting Free Benefits Counseling

Before starting any job, families should request a free Benefits Summary and Analysis (BS&A) from Ability360's Benefits 2 Work program (602-443-0720). Their certified Community Work Incentives Coordinators (CWICs) will model the exact impact of projected earnings on every benefit the individual receives — SSI, DAC, AHCCCS, ALTCS, SNAP, and any other program.

This counseling is free, funded by Social Security, and available to any SSI or SSDI beneficiary in Arizona. The analysis is customized to the individual's specific benefit combination, not a generic estimate.

The Arizona SSI at 18 & Adult Disability Benefits Guide includes a printable earned income calculator that models these scenarios with the current 2026 figures, so families can see the math before talking to a CWIC.
