Frequently Asked Questions
The taxable amount is based on your combined income (adjusted gross income + tax-exempt interest + 50% of Social Security benefits). Depending on your filing status, if combined income exceeds certain thresholds, up to 50% or 85% of benefits may be taxable.
Combined income includes your adjusted gross income (excluding Social Security), any tax-exempt interest, and half of your Social Security benefits.
No. If your combined income is below the base threshold for your filing status, none of your benefits are taxable. The thresholds are $25,000 for single, $32,000 for married filing jointly, and $0 for married filing separately (if you lived with your spouse).
