Should i choose traditional or roth 401k

1. You are currently in a lower tax bracket, but you expect that to change. Let’s say you are a young professional who is anticipating salary increases, which will put you in a higher tax bracket down the road. Contributing to a Roth IRA or Roth 401(k) means you pay the relatively low rate on taxable income now. Once you’ve retired, you will not pay any taxes on qualified distributions from the plan.

2. You are close to retirement and are concerned about RMDs. “If you’ve been a disciplined saver and have contributed a healthy percentage of your income to Traditional accounts for many years, eventually you’ve got to pay the piper,” says Young. Beginning in the year you reach age 72,* you must begin taking required minimum distributions (RMDs) from Traditional IRAs and from 401(k)s—including Roth 401(k)s—the later of age 72* or once you’re retired. As the name suggests, these withdrawals are required, even if you don’t need the income at the time.

RMDs could bump you to a higher tax bracket. Qualified distributions from a Roth 401(k) or Roth IRA, on the other hand, would not create taxable income or increase your tax rate. Therefore, a Roth contribution may be preferable in order to limit the RMD income taxed at a higher rate.

Someone in this position may also want to consider the effect on their beneficiaries. The SECURE Act, passed in 2019, requires most non-spouse beneficiaries to withdraw all retirement account balances within 10 calendar years. This change increases the likelihood that Traditional account withdrawals will push them into a higher tax bracket, which makes Roth assets even more attractive.

3. You are a prodigious saver. Suppose you can contribute the maximum amount to a retirement plan ($20,500 for 2022 or $27,000 if you’re over age 50), even if you don’t get a tax break. In this case, the Roth account effectively enables you to save more in a tax-advantaged manner. Saving the maximum amount ultimately results in more after-tax retirement assets for the Roth account balance than a Traditional contribution that is pretax.

If you have access to an employer-sponsored 401(k) plan, you may also have access to a Roth 401(k). Since 2006, the IRS has allowed companies to offer these types of retirement accounts, which applies many of the best features of a Roth IRA to a traditional 401(k). A survey by the Plan Sponsors of America (PSCA) on the state of 401(k) plans in 2020 found that 86.3% of 401(k) plans now offer a Roth version. Yet, PSCA reported that only 23% of plan participants chose to contribute to them, suggesting that Roth 401(k) plans, while getting more accessible, are still somewhat of a mystery.

Here's a breakdown of the differences between Roth 401(k)s and traditional 401(k)s, along with a few scenarios that will help you weigh which best suits your retirement planning. 

Understanding the similarities and differences

Roth and traditional 401(k)s are similar in many ways. They're both retirement saving plans with the same annual contribution limits. Both require that you be at least 59 ½ years old to withdraw your savings (without incurring a 10% IRS penalty), and both require minimum distributions at age 72 (unless you're still working). Neither have minimum or maximum income requirements. 

The money in each account grows tax-free, and you usually have the same investment options (mutual funds, ETFs, etc.) for both — whatever the plan sponsor offers.

How Roth and traditional 401(k)s differ

The key difference between a Roth and traditional 401(k) comes down to when your savings are taxed.

Traditional 401(k)s are pre-tax accounts, meaning the money comes straight "off the top" of your paycheck. As a result, you receive a current-year tax reduction of your income. In return, you'll pay income tax when you start withdrawing money, usually after you retire.

A Roth 401(k), like a Roth IRA, is a post-tax account: Your contributions do not lower your taxable income in the year that you make them. However, on the flip side, all qualified distributions — IRS-speak for withdrawals — of your earnings are tax-free. 

Here's how a Roth 401(k) and 401(k) differ on paper:

Traditional 401(k) vs Roth 401(k)

Employer match

Yes

Yes, but funds go into traditional 401(k) account

One thing to keep in mind is if your employer matches a portion of your traditional 401(k) contributions, there's a strong chance that it may offer the same match for your Roth 401(k) contributions as well. 

However, the money that your employer contributes will still go into a traditional 401(k) even if you opt for a Roth. These contributions are classified as pre-tax dollars and will be taxable when you withdraw from them.

Roth 401(k) vs. traditional 401(k): Which plan is best for you?

The most important question to ask yourself when comparing Roth and traditional 401(k) plans is "Do I expect my tax bracket to be higher or lower after I retire?"

If the answer is "lower," then a traditional 401(k) would make more sense. But if you expect to have a higher tax rate in retirement, a Roth 401(k) could be the better choice.

Two main factors could affect your tax rate after you've stopped working. The first is your target annual retirement income. If this figure is significantly less than your income during your earning years, that could strengthen the case for the traditional 401(k). But the opposite would be true if you think you might actually be enjoying a greater income in retirement.

The second factor to consider is future changes in income tax rates. Of course, that's out of your control, and in the hands of the IRS and the political powers-that-be. But, as Rob Williams, managing director of the Schwab Center for Financial Research says, current "tax rates are close to historical lows." Some economists and financial analysts predict that they are destined to rise in ensuing years. 

So it might be better to invest via a Roth 401(k) and take the tax hit now — especially if your retirement days are decades away. By going the Roth route, you know exactly what your tax liability will be now instead of hoping they stay low in the years to come.

Reasons to choose a traditional 401(k)

Here are three scenarios in which a retirement saver may want to choose the traditional 401(k) over the Roth option.

You're currently in your peak earning years.

If you expect your income to drop significantly in retirement, you'll probably want to stick to funding your traditional 401(k). "This is likely the case if you are in the peak of your career," with the capacity to earn and contribute the most, says Brandon Renfro, CFP® and retirement specialist.

By choosing a traditional 401(k) during these high-earning years, you get a tax deduction right now, when it'll benefit you the most. Then when you retire and you're in a lower tax bracket, you'll also owe the IRS less on your withdrawals.

You need to make withdrawals within 5 years of opening your 401(k)

Unlike a Roth IRA, a Roth 401(k) is actually less flexible when it comes to the timing of withdrawals than its traditional 401(k) counterpart.

You can begin making withdrawals from a traditional 401(k) penalty-free at age 59 ½. However, with a Roth 401(k), you'll need to wait at least five years from opening your account, regardless of how old you are, to avoid taxes and penalties (on earnings; you can withdraw your contribution amounts at any time). So if you open the account at age 58, you won't be able to make tax-free withdrawals until you reach age 63.

For twenty- and thirty-something workers, this won't be a concern. But if you're getting a late start on retirement savings or you've started working for a new employer near age 59½, you may want to stick with a traditional 401(k) to avoid this 5-year rule.

You can switch to a Roth 401(k)

Finally, "another advantage of a traditional 401(k) is that you can convert it into a Roth," says R.J Weiss, CFP® professional and founder of The Ways to Wealth.

This is an important benefit that is unique to traditional 401(k) contributions. You can't make a Roth contribution this year and then decide five years down the road to convert the contributions back to a pre-tax traditional 401(k).

But you can convert traditional 401(k) contributions to a Roth 401(k) at any time down the road, providing that you can pay the income taxes that will be due at the time. 

It's something to keep in mind if you think your tax strategy and financial situation might change. With this flexibility, you could wait to pay taxes on your 401(k) contributions until a below-average income year or after completing a move from a high income-tax state to one with lower tax rates.

Reasons to choose a Roth 401(k) 

Let's look at a few situations when you might be better off choosing a Roth 401(k).

Years of investing can overcome a higher tax bracket

When choosing between 401(k)s, Natalie Pine, CFP® professional at Briaud Financial Advisors, says, "We typically recommend that younger clients use Roth instead of traditional because their money grows tax-free for such a long time."

This is her recommendation even for a younger person who is currently in a high tax bracket. Why? "Because," she explains, "the tax-free growth usually overcomes the higher tax bracket over a long enough period of time."

You're looking to maximize other retirement benefits

Lowering your income taxes isn't the only way that a Roth 401(k) can save you money in retirement. 

For example, under current tax law, Roth distributions aren't included in the calculation for determining taxability of your Social Security benefits. And they also don't count as income in Medicare premium calculations.

You want to pass along tax-free money to your heirs

A Roth 401(k) can play a valuable role in your estate plan. With a traditional 401(k), your heirs will need to pay taxes on distributions just as you would. And, depending on your asset balance, this could generate a significant tax bill.

By choosing a Roth, you remove this tax burden for the loved ones who will inherit your 401(k). Plus, if you don't plan to use the funds yourself, you can roll a Roth 401(k) into a Roth IRA to get around the age 72 minimum distribution requirement.

The bottom line

When deciding between a Roth 401(k) and a traditional 401(k), many people look at it as an "either/or" decision. But, actually, "you can hedge your bets by doing both," Rob Williams says. "Most employers will allow you to choose which percentage goes into the Roth and which will go into the traditional."

If you'd rather not try to guess what your annual income or income tax rates will look like in the future, contributing to both types of 401(k)s in this way is the safest strategy. 

Otherwise, the younger you are, the more likely you are to benefit from contributing post-tax dollars to a Roth 401(k), regardless of your current tax bracket. But the pre-tax benefits of a traditional 401(k) could become more attractive as you age and your earning power increases.

Is it better to do a Roth 401k or traditional?

The main difference is the income taxes you pay on your contributions. With a traditional 401(k), you pay income taxes on any contributions and earnings you withdraw. With a Roth 401(k), income taxes only apply to your earnings since you have already paid up front on the money you put into the account.

Should I split my 401k into Roth and traditional?

In most cases, your tax situation should dictate which type of 401(k) to choose. If you're in a low tax bracket now and anticipate being in a higher one after you retire, a Roth 401(k) makes the most sense. If you're in a high tax bracket now, the traditional 401(k) might be the better option.

Should I contribute to Roth or traditional 401k first?

Key Takeaways. Contributing as much as you can and at least 15% of your pre-tax income is recommended by financial planners. The rule of thumb for retirement savings says you should first meet your employer's match for your 401(k), then max out a Roth 401(k) or Roth IRA. Then you can go back to your 401(k).

Is there a downside to Roth 401k?

It may cost you more on the front end to use a Roth 401(k). Contributions to a Roth 401(k) can hit your budget harder today because an after-tax contribution takes a bigger bite out of your paycheck than a pretax contribution to a traditional 401(k). The Roth account can be more valuable in retirement.
