Does Connecticut tax Social Security benefits?

Yes — with exemptions for many retirees.

Connecticut taxes Social Security benefits only above income thresholds: benefits are fully exempt for single filers under $75,000 and joint filers under $100,000 of federal AGI. Above those limits, up to 25% of benefits may be taxable.

Note: this covers state tax only. The federal government may tax up to 85% of your benefits depending on your combined income, regardless of where you live.
