SSI Eligibility Requirements
To qualify for SSI, you must meet all three criteria:
- Categorical eligibility: Age 65+, legally blind, or have a qualifying disability
- Income limits: Your countable income must be below the SSI payment amount
- Resource limits: $2,000 for individuals, $3,000 for couples (not all assets count)
2024 SSI Payment Amounts
| Recipient | Maximum Federal Benefit |
|---|---|
| Individual | $943/month |
| Couple (both eligible) | $1,415/month |
| Essential person (caregiver) | $472/month additional |
Many states supplement the federal SSI amount. Your actual payment depends on your income — SSI reduces by $1 for every $2 of earned income (after exclusions).
Income That Doesn't Count
Not all income reduces your SSI. The SSA excludes:
- First $20/month of most income (general exclusion)
- First $65/month of earned income + half of remaining earnings
- SNAP benefits and most housing assistance
- Impairment-related work expenses
- Student earned income (if under 22 and in school)
Resources That Don't Count
- Your primary home and the land it's on
- One vehicle (if used for transportation)
- Household goods and personal effects
- Life insurance policies with face value under $1,500
- Burial funds up to $1,500
- ABLE account funds (up to $100,000)
