A relative had purchased an annuity for me years ago, which was payable upon her death. I was instructed to cash in the annuity, which I did. Is the annuity fully taxable as income on my IRS return? Is the gross distribution listed in box 1 added to my income, and therefore fully taxable? Or do I list the amount in box 2a (taxable amount) as income, making the distribution only partially taxable?
