The total tax liability is $12,500.
Due to the fact that the account is qualified annuity, the total amount withdrawn is subject to tax. Also, because the investor is less than 59.5 years, the investor pays an additional tax of 10%.
The effective total tax = 25% + 10% = 35%
Total tax liability = 25% x $50,000
= 0.25 x $25,000 = $12,500
