Yes, your annuity is income.
A
quick way to find out if any of your benefits may be taxable is to add one-half
of your Social Security benefits to all your other income, including any
tax-exempt interest. Next, compare this total to the base amounts below. If
your total is more than the base amount for your filing status, then some of
your benefits may be taxable. The three base amounts are:
- $25,000 - for single, head of household, qualifying widow
or widower with a dependent child or married individuals filing separately
who did not live with their spouse at any time during the year
- $32,000 - for married couples filing jointly
- $0 - for married persons filing separately who lived
together at any time during the year
