According to ICI research, as of 2023, Americans held approximately $13.6 trillion in individual retirement accounts (IRAs), which is about 35% of all retirement savings in the U.S. Despite this, many people are unsure about the best strategies for saving for retirement. Alarmingly, while 68% of workers report feeling confident about their retirement plans, 1 in 4 adults have no savings at all.
This guide is here to help bridge that gap. We'll break down what a Roth IRA is, how it compares to other retirement options, and how you can use it to build a tax-free financial future.
Key Takeaway
A Roth IRA allows for tax-free growth and withdrawals in retirement, making it a powerful tool for long-term savings.
Contribution limits for 2025 are $7,000 ($8,000 if aged 50 or older), with income eligibility determined by your MAGI.
Roth IRAs differ from traditional IRAs in that they offer after-tax contributions and no required minimum distributions.
Combining a Roth IRA with other accounts like a 401(k) provides diversified tax advantages for retirement planning.
What is a Roth IRA?
A Roth IRA is a special type of retirement savings account introduced in 1997 to help Americans save for the future. It’s named after Senator William Roth, who supported its creation. The big advantage of a Roth IRA is its tax benefits, which make it a popular choice for retirement planning.
Here’s how it works: You contribute money to the account using after-tax dollars, meaning you don’t get a tax break upfront. But in return, your money grows tax-free, and when you withdraw it in retirement, you won’t pay federal income tax on it. This can be a huge benefit, especially if you expect to be in a higher tax bracket later in life.
Roth IRAs are a great choice for people with steady incomes who can handle making contributions without an immediate tax deduction. They’re especially useful for younger savers, who can take advantage of decades of tax-free growth. Even minors with earned income can get started with a custodial Roth IRA, giving them a head start on saving and building good financial habits early.
Benefits of Roth IRA Accounts
Why should you consider a Roth IRA? Here are some key advantages:
Tax-Free Withdrawals: One of the biggest perks is that qualified withdrawals in retirement are tax-free. This can provide peace of mind and certainty for your financial future.
No Required Minimum Distributions (RMDs): In contrast to traditional IRAs, Roth IRAs don’t require you to start withdrawing funds at age 73. This allows your investments to continue growing tax-free for as long as you want.
Flexibility: You can access your contributions (but not earnings) at any time without penalty. This makes a Roth IRA a more flexible option than other retirement accounts.
Estate Planning Benefits: Roth IRAs can be passed on to heirs tax-free, making them a valuable tool for legacy planning.
Long-Term Growth: With compounding interest and no tax drag, Roth IRAs are a powerful way to build wealth over time.
How Does a Roth IRA Work?
A Roth IRA is simple in concept but offers powerful potential for growth. Here’s how it works:
- Contributions: You fund a Roth IRA with after-tax dollars. For 2025, the contribution limit is $7,000 ($8,000 for those aged 50 or older). However, there are income limits to consider, which we’ll discuss later.
- Growth: Once you contribute, your money can be invested in a variety of assets, such as stocks, bonds, mutual funds, or ETFs. The growth on these investments is tax-free.
- Withdrawals: You can withdraw your contributions at any time without taxes or penalties. However, earnings withdrawals are subject to specific rules.
Let’s say you contribute $5,000 annually to a Roth IRA and earn an average annual return of 7%. After 10 years, your account could grow to over $70,000, with nearly $20,000 coming from tax-free growth. Using a Roth IRA calculator can help you estimate your potential returns and plan for the future.
Fast Fact
Your Roth IRA contributions cannot exceed your total earned income for the year. For instance, if you earn $5,000 in 2025, your maximum contribution limit would also be $5,000, even though the annual cap is higher.
Roth IRA vs Traditional IRA
Roth IRAs and Traditional IRAs are popular retirement savings tools, but they differ in key ways, particularly in tax treatment and flexibility.
Tax Treatment
With a Roth IRA, you contribute money that’s already been taxed. When you retire, you can take out both your contributions and the earnings completely tax-free. A Traditional IRA, on the other hand, often allows for tax-deductible contributions, offering immediate tax savings, but withdrawals in retirement are taxed as ordinary income.
Eligibility
Income eligibility also sets these accounts apart. Roth IRAs have income limits, with contributions phasing out at higher income levels. Traditional IRAs have no income limits for contributions, but deductibility can be restricted if you or your spouse participate in a workplace retirement plan.
Required Distributions
RMD rules add another difference: Traditional IRAs require minimum distributions starting at age 73, potentially forcing withdrawals even if you don’t need the funds. Roth IRAs have no such requirement, allowing your investments to grow tax-free for as long as you like.
For example, someone in a low tax bracket during retirement may benefit from a Traditional IRA's upfront tax deduction. However, if you expect to be in a higher tax bracket later, the Roth IRA’s tax-free withdrawals can offer substantial long-term savings.
In short, Roth IRAs favour future tax advantages, while Traditional IRAs provide immediate tax relief, making a choice highly dependent on individual financial goals.
Fast Fact
In 2025, the combined contribution limit for both a Roth IRA and a traditional IRA is capped at $7,000 if you’re under 50.
401(k) vs Roth IRA
Both Roth IRAs and 401(k)s are powerful retirement accounts, but they cater to different needs and scenarios.
Employer-Sponsored vs. Individual Accounts
A 401(k) is offered through your employer and often includes the added benefit of matching contributions. This means your employer may match a portion of your contributions, effectively giving you free money to grow your savings. In contrast, a Roth IRA is an individual account that you open and manage independently, providing more flexibility in investment options.
Contribution Limits
A key distinction is the annual contribution limit. A 401(k) allows for significantly higher contributions, with a cap of $22,500 in 2025 (or $30,000 for individuals aged 50+). Meanwhile, the Roth IRA limit is $7,000 (or $7,500 if aged 50+).
Tax Treatment
Roth IRAs are funded with after-tax dollars, meaning withdrawals in retirement, including earnings, are entirely tax-free. Traditional 401(k)s, on the other hand, provide an immediate tax break by deferring taxes on contributions, but withdrawals in retirement are taxed as ordinary income.
For many, the optimal strategy is to utilise both accounts, balancing the tax-free growth of a Roth IRA with the upfront tax benefits and higher limits of a 401(k). This combination provides a diversified approach to retirement savings, maximising the advantages of each.
Roth IRA Income Limits and Eligibility
As of 2025, the IRS has updated certain parameters for Roth IRAs:
You can contribute the full amount if your modified adjusted gross income (MAGI) is less than $150,000. The contribution limit phases out for MAGI between $150,000 and $165,000. If your MAGI exceeds $165,000, you're ineligible to contribute directly to a Roth IRA.
Full contributions are allowed for MAGI under $236,000. The phase-out range is between $236,000 and $246,000. MAGI over $246,000 disqualifies you from direct Roth IRA contributions.
How to Open a Roth IRA
Opening a Roth IRA is a simple process that can be completed in a few steps:
- Choose a Provider: Research banks, brokerages, or robo-advisors to identify the best Roth IRA accounts for your needs. Compare Roth IRA interest rates, investment options, account minimums, and customer service. Popular providers include Fidelity, Vanguard, and Charles Schwab.
- Gather Documents: Have your identification, Social Security number, and income details ready. You may also need your bank account information to fund the account.
- Fund the Account: Decide how much to contribute, keeping annual limits in mind. You can fund the account with a one-time deposit or set up automatic recurring transfers.
- Select Investments: Based on your goals and risk tolerance, choose from mutual funds, ETFs, stocks, or bonds. Many providers offer tools or pre-built portfolios to help beginners.
- Start Investing: Once your account is funded, monitor your investments regularly. Adjust your strategy over time to align with changes in your goals or market conditions.
Roth IRA Withdrawal Rules
Understanding withdrawal rules helps you avoid penalties and make the most of your Roth IRA:
Contributions: You are free to withdraw your contributions whenever you want without taxes or penalties.
Earnings: Earnings are subject to a 10% penalty and income taxes if withdrawn before age 59½ unless they qualify for an exception.
Qualified Withdrawals: Certain scenarios, such as using up to $10,000 for a first-time home purchase or paying qualified education expenses, allow penalty-free withdrawals of earnings.
Certain exceptions, like using funds for a first-time home purchase, allow penalty-free withdrawals.
Conclusion
A Roth IRA is a powerful tool that you can use to build a strong financial future. It offers tax-free growth, flexible withdrawal options, and no required minimum distributions—giving you greater freedom in managing your retirement savings.
The best time to start investing in a Roth IRA is as early as possible. The longer your money has to grow, the more you can benefit from compounding interest. Even small, consistent contributions can turn into a significant retirement fund over time.
