States taxing Social Security (2026)
| State | How it treats Social Security |
|---|---|
| Colorado | Age-tiered: full exemption 65+, partial relief 55-64, full tax under 55 |
| Connecticut | Exempt below threshold, 25% of gross taxed above |
| Minnesota | Subtraction phases out above threshold |
| Montana | Always taxed (federal conformity) |
| New Mexico | Exempt below threshold, full tax above (cliff) |
| Rhode Island | Exempt only at Full Retirement Age (67)+ and below threshold |
| Utah | Credit phases out above threshold |
| Vermont | Exemption ramps out above threshold |
Several of these states exempt benefits below an income threshold, so many residents still owe nothing.
