Choosing Between Traditional and Roth 401(k)s
The Roth 401(k) may appeal to workers willing to forgo a tax break now in return for getting one at retirement. As its name implies, the Roth 401(k) combines features of a traditional 401(k) with those of a Roth IRA.
As with a traditional 401(k), workers enjoy the convenience of contributing through payroll deduction. But as with a Roth IRA, contributions are made on an after-tax basis, and withdrawals after age 59½ are tax free and penalty free for workers who have maintained their account for five tax years. Designated Roth 401(k) may also be added to 403(b) plans, which are commonly used by schools, hospitals, and government entities.
How a Roth 401(k) Works
The Roth 401(k) follows many of the same rules as a traditional 401(k). For the 2020 tax year, federal laws permit a maximum annual contribution of $19,500, although your employer may impose a lower limit. Your employer may provide a matching contribution as part of a Roth 401(k), but any matching contributions must be separately accounted for, and distributions from that account will be subject to taxation. If you are age 50 or older, you may contribute an additional $6,500 to a designated Roth 401(k) for a total contribution of $26,000 in 2020.
You may continue to maintain a traditional 401(k) while directing all or a portion of new contributions to a Roth 401(k). Your contributions to a Roth 401(k), however, are irrevocable -- once made, they cannot be transferred to a traditional 401(k) account. Your plan may allow you to make in-plan rollovers from a traditional 401(k) account to a designated Roth 401(k), but any previously untaxed amounts will be subject to taxes in the year of conversion. Generally, both Roth and traditional 401(k)s require minimum distributions after age 72.1
Planning for Retirement
A Roth 401(k) may present a significant benefit when it's time for retirement -- the funds can be rolled over directly to a Roth IRA with no tax payment. Assets in a traditional 401(k) can also be converted to a Roth IRA, but the conversion requires you to pay taxes on the portion of the rollover that has not yet been taxed.

To Roth or Not to Roth?
If you're considering a Roth 401(k), you may want to review the following points before making your decision:
- Although future tax rates are difficult to predict, you may benefit from a Roth 401(k) or 403(b) if you anticipate being in a higher tax bracket during retirement.
- Even if your marginal tax rate remains relatively stable, you may face a higher tax bill in retirement if you will no longer claim deductions for mortgage interest and other types of deductions frequently used by families. If this sounds like a likely scenario, a Roth 401(k) may be to your advantage.
- Will you need your retirement assets for living expenses during your later years? If not, a Roth 401(k) offers the opportunity to roll over funds directly to a Roth IRA, which does not require distributions by the owner after he or she turns 72. This situation may enhance the potential tax-free growth of your assets and enable you to bequeath a potentially larger portion of your assets to your heirs.
- For 2020, eligibility to contribute to a Roth IRA begins to phase out for single taxpayers with modified adjusted gross income (MAGI) of $124,000 and married couples filing jointly with MAGI of $196,000 or higher. A Roth 401(k) may have some appeal if your eligibility to contribute to a Roth IRA is affected by these thresholds.
- The longer you remain invested in a Roth 401(k), the more you are likely to benefit from tax-free growth. If you plan to retire in five years or less, a shorter term time horizon may limit the benefit of tax-free withdrawals, whereas your account may get a bigger boost from tax-free savings if you plan to continue working for a longer period of time.
Capitalizing on every option available to you may make it easier to pursue your long-term savings goal. If tax-free withdrawals could potentially benefit you, and your employer makes a Roth 401(k) available, consider adding it to your retirement planning mix.
