Pros and cons of a 401(k)

Pros and cons of a 401(k) Pros

Tax-advantaged growth. Traditional 401(k) plans take pretax contributions, reducing taxable income for the year. You might also have access to a Roth 401(k), which requires after-tax contributions but offers tax-free withdrawals in retirement.

Employer match. This free money can boost your retirement savings.

Higher contribution limits. You can contribute more to a 401(k) than to an individual retirement plan (IRA).

Potential for conversions. Some plans may let high earners convert funds in their 401(k) plan into a Roth IRA through a Roth IRA conversion. This provides tax-free withdrawals in retirement and may provide more investment options.

Cons

Limited investment options. Investment choices are limited to the options provided by the plan.

Potential vesting period. Some 401(k) plans may require that you work at your employer for a certain number of years before you can be fully vested in your 401(k) plan.

Rules for early withdrawals. An early withdrawal from your 401(k) plan might incur taxes and penalties, depending on the reason.
