Roth IRAs and traditional IRAs are very similar, but they differ in how they are taxed. With a traditional IRA, contributions will be taxed upon the withdrawal of funds from the account. With a Roth IRA, you pay taxes on the contributions you place in the account and you do not pay a tax once you withdraw the money at the age 59 ½ or older. If you withdraw before the age of 59 ½ with either a traditional or Roth IRA, you are subject to an additional 10% tax for early withdrawals unless you qualify for an exception.

Both Roth IRAs and traditional IRAs provide tax-free growth of your contributions until you retire, which is why finding the right online broker to build your retirement wealth is crucial. The brokers we selected have excellent retirement planning and reporting tools. We also looked at low or no annual fees for managing your IRA, so you can keep that money growing for your retirement.

Why You Should Consider a Roth IRA

Roth IRAs are fantastic investment vehicles. This is because they are heavily advantaged against taxes. Here are some reasons that a Roth IRA can be a great opportunity:

  • Tax-advantaged: Pay taxes on your contributions now and not when you withdraw your money. This also means that not only do the earnings your account makes grow tax-free while they're in the account—you will not be hit with capital gains tax—but that when you withdraw money from your account at retirement, you will pay zero taxes on it. If you believe you'll be in a higher tax bracket when you retire then this is a huge advantage.
  • No required minimum distributions (RMD)s: There is no age at which you are forced to withdraw money due to RMDs. This means that you can leave the entire account to a child or grandchild, providing years of tax-free distributions.
  • Ability to withdraw contributions: With your taxes already paid, you can withdraw your contributions at any time, both tax and penalty-free. Contributions refer to the money that you put in and not investment earnings on those contributions. It also lets you use your Roth as a backup emergency fund, should you need it.
  • Tax Diversification in retirement: When you begin to withdraw from retirement accounts, such as your 401(k) and traditional IRA, your taxable income will rise. This could cause your tax bracket to rise as well. But because the money in the Roth account is not taxable income, it lets you shuffle distributions so that you do not push yourself into a higher tax bracket. This is especially useful in the years before you hit 70½ when RMDs kick in.

Who Are Roth IRAs Best For?

Roth IRAs are best for those whose modified adjusted gross income (MAGI) is under the limit for 2020 ($124,000 if single and $206,000 if married), and for those who believe that they will be in a higher tax bracket when they retire than they are now.

Regardless, it's always beneficial to have your retirement savings tax-diversified. Note that singles with MAGIs between $124,000 and $139,000 ($196,000 and $206,000 for those married filing jointly) can make reduced contributions to a Roth IRA.

Tax diversification means having a variety of retirement accounts with the goal of maximizing withdrawals without pushing yourself into a higher tax bracket. Here's how it works: When you can withdraw penalty-free money from your retirement accounts starting at age 59 ½, you withdraw from your traditional IRA savings just up to the limit of the next tax bracket. You can then take additional savings out of your Roth IRA, as it does not add to your taxable income because it was already taxed when it was first contributed. This lets you keep your taxable income low while being able to take a larger sum out of your retirement accounts.

How Do You Qualify for a Roth IRA?

  • If single: must have a modified adjusted gross income under $139,000 to contribute, but contributions are reduced starting at $124,000.
  • If married filing jointly: modified adjusted gross income must be less than $206,000, with phaseout starting at $196,000.

How Much Can I Contribute to a Roth IRA?

For 2019 and 2020, you can contribute a maximum of $6,000 ($7,000 if you’re 50 or older by the end of the year) or your taxable compensation for the year, if it's below the permitted number.

How Does a Roth IRA Grow?

A retirement account—whether it is a traditional IRA, Roth IRA, or 401(k)—builds up as you contribute to the account. These accounts also grow over time due to compounding interest. Compounding means that every year your contributions earn interest, your balance increases. The following year, you earn interest on the increased balance. As a result, the total amount of interest earned increases each year, even if you are no longer contributing to your account.

In addition to interest-bearing accounts, retirement money, including funds in your Roth IRA, can be invested in the markets. These funds could be placed into stocks, ETFs, mutual funds, and a number of other financial assets. When these assets go up in value, they can significantly grow the value of your retirement account.
