Final answer:
B. Roth 401(k)
Among the given plans, the Roth 401(k) is the one in which employee contributions are made with after-tax dollars and are not taken on a pre-tax basis.
Step-by-step explanation:
The plan that allows employee contributions to be taken on a pre-tax basis except for one is key to understanding the options provided. Of the options given:
- A. Traditional 401(k) - Contributions are made pre-tax, reducing taxable income.
- B. Roth 401(k) - Contributions are made with after-tax dollars, so taxes are paid upfront rather than at withdrawal.
- C. SIMPLE IRA - Like traditional 401(k)s, contributions to a SIMPLE IRA are pre-tax.
- D. Health Savings Account (HSA) - Contributions can also be made pre-tax to an HSA.
Given these descriptions, the Roth 401(k) is the plan where employee contributions are not taken on a pre-tax basis; instead, they are contributed after taxes have been applied to the income.
