Surrender of policy for cash. If you surrender a life insurance policy for cash, you must include in income any proceeds that are more than the cost of the life insurance policy. In general, your cost (or investment in the contract) is the total of premiums that you paid for the life insurance policy, less any refunded premiums, rebates, dividends, or unrepaid loans that were not included in your income.
You should receive a Form 1099-R showing the total proceeds and the taxable part. Report these amounts on lines 16a and 16b of Form 1040.
