SSI vs Social Security: Need-Based vs Earned, Side by Side
Social Security is insurance you earn by working; SSI is a needs-based payment for people 65 or older, blind or disabled with very little income and savings. Many people get both. (SSA: SSI amounts)
| Social Security | SSI | |
|---|---|---|
| Paid for by | Payroll taxes | General tax revenue |
| Who qualifies | Workers with 40 credits, families | 65+, blind or disabled, low income and assets |
| 2027 amount | Based on your earnings | Up to $1,029 (couple $1,544) |
| Asset limit | None | $2,000 ($3,000 couple) |
| Paid on | 2nd–4th Wednesday | The 1st |

Can You Get SSI and Social Security? The $20 Rule Decides
You can, as long as your Social Security minus $20 is less than the SSI rate. SSI ignores the first $20 of income and subtracts the rest dollar for dollar. A $640 Social Security check leaves $620 countable, so 2027 SSI is about $409. (SSA: SSI income exclusions)
- Social Security of $1,029 plus $20 or more: no federal SSI.
- Wages count more gently: SSI ignores the first $65 and half the rest.
- Couples share one $20 exclusion.
When you get both, Social Security moves to the 3rd of the month and SSI comes on the 1st — see the 2027 payment schedule.

Our take: apply even if you think you have "too much"
If your Social Security is close to the SSI rate, the SSI check may be small, but it usually unlocks Medicaid, which can pay your Medicare premiums and copays. That's often worth more than the SSI itself. Check whether a Medicare Savings Program or Extra Help covers you too.
