SSI Earned Income Calculation — How Washington Benefits Change When You Work
The Formula SSA Actually Uses
The Social Security Administration reduces SSI benefits when a recipient earns wages, but the formula is more generous than most families expect. For every $2 of earned income above certain exclusions, the SSI payment drops by $1. Here's the exact sequence SSA follows in 2026.
Step 1: Subtract the $20 general income exclusion. This exclusion applies to any income — earned or unearned. SSA applies it to unearned income first. If the recipient has no unearned income (common for a young adult whose only income is a part-time job), the full $20 applies against earned income.
Step 2: Subtract the $65 earned income exclusion. This is a flat deduction that applies only to wages and self-employment income, every month, regardless of how much the person earns.
Step 3: Divide the remainder by 2. The result is the "countable earned income" — the amount SSA subtracts from the federal benefit rate.
Step 4: Subtract countable earned income from $994 (the 2026 federal benefit rate). The result is the new SSI payment.
Worked Example: $1,200 in Monthly Wages
A 19-year-old in Washington works part-time stocking shelves and earns $1,200 per month. No unearned income.
| Step | Calculation | Result |
|---|---|---|
| Gross earned income | $1,200 | |
| Subtract $20 general exclusion | $1,200 − $20 | $1,180 |
| Subtract $65 earned income exclusion | $1,180 − $65 | $1,115 |
| Divide by 2 | $1,115 ÷ 2 | $557.50 |
| Subtract from FBR | $994 − $557.50 | $436.50 |
Total monthly income: $1,200 wages + $436.50 SSI = $1,636.50. Working increased total income by $642.50 compared to SSI alone — substantially more than the $1,200 earned, minus the $557.50 reduction.
Washington's $33 state supplement is calculated separately and may also be reduced, but the federal formula above determines the SSI portion.
The Student Earned Income Exclusion
Recipients under 22 who attend school or vocational training regularly qualify for the Student Earned Income Exclusion, which is far more powerful than the standard formula.
In 2026, the SEIE excludes up to $2,410 per month of earned income, with an annual cap of $9,730. This exclusion applies before any other deduction.
Using the same $1,200 in wages — but now the recipient is a 20-year-old enrolled in a community college program:
| Step | Calculation | Result |
|---|---|---|
| Gross earned income | $1,200 | |
| Subtract SEIE | $1,200 − $1,200 | $0 |
| Countable earned income | $0 | |
| SSI payment | $994 − $0 | $994 |
The full SSI benefit is preserved. Total monthly income: $1,200 + $994 = $2,194. The SEIE effectively makes the first $2,410 of monthly earnings invisible to SSA's benefit calculation.
Once the $9,730 annual cap is exhausted — during the ninth month for someone earning $1,200/month — the standard formula kicks in for remaining months.

PASS Plans: Sheltering Income for a Work Goal
A Plan to Achieve Self-Support (PASS) lets a recipient set aside income and resources toward a specific vocational goal — starting a business, completing training, buying work equipment — without those amounts counting against SSI.
Income diverted to an approved PASS plan is excluded from the earned income calculation entirely. If the same $1,200 earner commits $400/month to a PASS plan for job coaching certification:
| Step | Calculation | Result |
|---|---|---|
| Gross earned income | $1,200 | |
| Subtract PASS set-aside | $1,200 − $400 | $800 |
| Subtract $20 general exclusion | $800 − $20 | $780 |
| Subtract $65 earned income exclusion | $780 − $65 | $715 |
| Divide by 2 | $715 ÷ 2 | $357.50 |
| SSI payment | $994 − $357.50 | $636.50 |
Total: $1,200 wages + $636.50 SSI = $1,836.50, with $400 going toward a career goal. Washington's BenefitU platform (free for DDA-eligible clients aged 14 and older) and certified WIPA benefits counselors can help structure and submit the PASS application.
Impairment-Related Work Expenses
If a recipient pays for disability-related costs that enable them to work — specialized transportation, attendant care at the job site, medications, prosthetics, or service animal expenses — those costs are deducted from gross earnings before SSA runs the formula.
These deductions stack with the earned income exclusion and SEIE. A recipient whose $150/month job-coaching cost qualifies as an IRWE would subtract that $150 from gross wages at the very beginning of the calculation.
When Earnings Reduce SSI to Zero
As earned income rises, SSI eventually reaches zero. In 2026, the break-even point — where SSI phases out completely — is roughly $2,073 per month in gross earnings (no SEIE, no PASS, no IRWE).
At that point, Section 1619(a) status kicks in automatically. The recipient is considered an SSI recipient for Medicaid purposes even though their cash payment is zero. If earnings continue to rise, Section 1619(b) protects Apple Health coverage as long as annual earnings stay below Washington's $73,897 threshold for 2026.
