Answer: $15,000 ordinary income
Explanation: Tax is paid on the profit or the difference in the contributed amount and the cash surrendered. Tax isn't paid on the contributed amount or when the contributed amount hasn't been surrendered.
The interest is calculated as the difference between the cash surrendered and the amount contributed. The interest accrued is the taxable amount.
Therefore, $40,000 - $25,000 = $15,000
Interest = $15,000
Non-qualified variable annuity is being taxed as ordinary income under the federal income tax law.
