Roth IRA vs. Traditional IRA

The two main types of IRAs differ mainly in how and when your money is taxed. But several features make the Roth a better choice for most eligible retirement savers.

Roth vs. traditional: How to choose

The biggest difference between a Roth and a traditional IRA is how and when you get a tax break: The tax advantage of a traditional IRA is that your contributions are tax-deductible in the year they are made. The tax advantage of a Roth IRA is that your withdrawals in retirement are not taxed.

Thus most advice on the Roth IRA versus traditional IRA topic begins with a question: Do you think your tax rate will be higher or lower in the future?

If you can answer that question definitively, you can theoretically choose the type of IRA that will give you the biggest tax savings: If you expect your tax rate to be higher in retirement, choose a Roth IRA and its delayed tax benefit. If you expect lower rates in retirement, choose a traditional IRA and its upfront tax advantage.

One problem with this approach: It's hard to anticipate what your tax rate will be in retirement, particularly if you're decades away from leaving the workforce.

Fortunately, there are other ways to determine whether a Roth or traditional IRA is best for you.

First things first: Check your IRA eligibility

The IRS rules on IRA eligibility may make the Roth-versus-traditional decision for you.

Your income will determine:

  1. If you're eligible to contribute to a Roth.

  2. How much of your contribution to a traditional IRA you can deduct from this year’s taxes. Traditional IRA deductibility is restricted only if you or your spouse has access to a workplace savings plan like a 401(k).

Traditional IRA income limits for 2019 and 2020

These income limits apply only if you (or your spouse) has a retirement plan at work. The limits are based on modified adjusted gross income, which is your adjusted gross income with some deductions added back in. (See IRS Publication 590-A, Worksheet 1-1, for instructions on figuring MAGI for traditional IRAs.)

Roth IRA income limits for 2019 and 2020

These income limits are based on modified adjusted gross income, which is your adjusted gross income with some deductions added back in. (See IRS Publication 590-A, Worksheet 2-1, for instructions on figuring MAGI for Roth IRAs.)

Worth noting: You can contribute to a traditional and a Roth IRA during the same year, as long as the total amount does not exceed the maximum allowable contribution limit. In both 2020 and 2019, the most an individual is allowed to contribute per year is $6,000, or $7,000 if you’re age 50 or older. (Those limits are up from $5,500 and $6,500 in 2018.)

Spoiler alert: The Roth IRA comes out ahead in most of the categories.

Why the Roth IRA works for most savers

Most of the ink devoted to Roth and traditional IRAs focuses on the difference between how the accounts tax contributions and withdrawals. But when it comes to what you’re allowed to do with the money while it’s in the account, the Roth earns bonus points for its versatility.

Here’s why we generally recommend the Roth over a traditional IRA for those who qualify.

1. Early withdrawal rules are much more flexible with a Roth. Although we discourage early withdrawals from retirement accounts, if you do have to break the seal on the cookie jar, the Roth allows you to withdraw contributions — money you put into the account; not earnings — at any time without having to pay income taxes or an early withdrawal penalty.

Dip into a traditional IRA before retirement and the IRS isn’t as lenient: You’ll likely be socked with a hefty 10% early withdrawal penalty and owe taxes at your current income tax rate on the money you take out. There are a few exceptions to this rule — see our page on traditional IRA distribution rules for details — but you’ll need to proceed much more carefully than you would with a Roth.

2. The Roth has fewer restrictions for retirees. Traditional IRAs require you to start taking required minimum distributions (RMDs) at age 70½.

The Roth is friendlier to the silver-haired set. Unless you’re inheriting the Roth IRA, it has no required minimum distribution rules: You’re free to let your savings stay put in the account to continue to grow tax-free as long as you live.

3. Roth IRAs make it easier to pass money to your heirs. Another bonus that the traditional IRA doesn’t offer? Unlike a traditional IRA, which doesn’t allow additional contributions past the age of 70½, the Roth allows you to continue contributing to the account at any age, as long as you still qualify.

The opportunity to continue to save as well as let your money continue to grow under the tax protection of the account makes the Roth a better parking spot for cash you intend to leave to loved ones.

4. Unless you’re an extremely disciplined saver, you’ll end up with more after-tax money in a Roth IRA. Yes, both types of IRAs offer you a tax break. But there’s an oft-overlooked benefit to the way the Roth treats taxes: Because your tax break doesn’t arrive till retirement (via tax-free withdrawals), you won’t be tempted to spend it before then. With a traditional IRA, the tax benefit is delivered annually when you file your taxes, which makes it easy to fritter the money away on any number of things.

To come out even in terms of after-tax savings, you have to be disciplined enough to invest the traditional IRA tax savings you get every year back into your retirement savings. If that seems unlikely to happen, then you’d be better off saving in a Roth, where you’ll arrive at retirement with more after-tax savings.

5. Funding a Roth in conjunction with your 401(k) provides tax diversification. The classic 401(k) plan offered by most employers provides the same tax benefits as a traditional IRA. Although some workplaces are adding a Roth 401(k) option for employees, if yours doesn’t, diverting some of those retirement savings dollars into a Roth IRA will give you more options for managing your tax burden in retirement.

Making the call

The sole advantage of a traditional IRA for most people is the upfront tax break. And we’re not dismissing this benefit: It can be a huge advantage for high earners and a great incentive for people who might otherwise skip saving for retirement. In the short term, it effectively makes it “cheaper” to save for retirement, since the tax savings each year reduces the cost of your contributions.

But you will eventually have to face that tax burden in retirement, which means unless you really need that upfront tax break, it’s hard to go wrong with a Roth IRA. Still, don’t take our word for it: Browse the key differences between the accounts below and make your own call.
