What Is an IRA? A Complete Guide to Traditional and Roth IRAs

Executive Summary

An IRA, or Individual Retirement Account, is one of the most flexible retirement savings tools available to American workers. Unlike a 401(k), which you access through an employer, an IRA is opened directly with a brokerage or custodian, giving you full control over your investment lineup and fees. There are two main types: the Traditional IRA, which is funded with pre-tax dollars and grows tax-deferred, and the Roth IRA, which is funded with after-tax dollars and grows completely tax-free. For 2026, individuals can contribute up to $7,500 across all their IRAs combined ($8,600 for those 50 and older). The right choice — Traditional, Roth, or both — depends on your current tax bracket, your expected tax bracket in retirement, and whether you also have access to a workplace plan like a 401(k). This guide breaks down how each account works, the pros and cons of each, how IRAs stack up against a 401(k), and how taxation actually works for both, so you can have an informed conversation with a fiduciary advisor about which fits your situation.

What Is an IRA?

An IRA (Individual Retirement Account) is a tax-advantaged investment account, opened by an individual rather than an employer, designed specifically to help you save for retirement.

Anyone with earned income can open an IRA — you don't need an employer-sponsored plan to qualify. IRAs are a cornerstone of sustainable retirement planning because they offer either tax-deferred growth or tax-free growth, depending on the type you choose, on top of whatever investment returns your portfolio earns.

An IRA isn't an investment itself — it's a container for investments. Inside an IRA, you can typically hold:

• Individual stocks and bonds
• Mutual funds and ETFs
• CDs and money market funds
• Other securities offered by your custodian

Because an IRA is self-directed and not tied to a specific job, it moves with you throughout your career, which is one reason it's a common landing spot for old 401(k) balances through a rollover.

The two main types of IRAs are the Traditional IRA and the Roth IRA. Less common variations — like the SEP IRA and SIMPLE IRA — are designed for self-employed individuals and small business owners, but this guide focuses on the two accounts most individual savers use.

How Does a Traditional IRA Work?

A Traditional IRA lets you contribute pre-tax (or tax-deductible) dollars, your investments grow tax-deferred, and you pay ordinary income tax when you withdraw the money in retirement.

Here's the mechanism in plain terms:

1. You contribute. Depending on your income and whether you (or your spouse) are covered by a workplace retirement plan, your contribution may be fully or partially tax-deductible in the year you make it.
2. Your money grows tax-deferred. You don't pay taxes on dividends, interest, or capital gains inside the account year to year.
3. You pay tax on withdrawal. When you take distributions in retirement, they're taxed as ordinary income — not capital gains.
4. Required Minimum Distributions (RMDs) apply. Under current law, you're required to start withdrawing a minimum amount each year once you reach the applicable RMD age (73 or 75 under current rules), whether you need the income or not.

There are no income limits that prevent you from contributing to a Traditional IRA, but there are income limits that determine whether your contribution is tax-deductible if you're also covered by a workplace plan.

What Are the Pros and Cons of a Traditional IRA?

The main advantage of a Traditional IRA is an upfront tax deduction and tax-deferred growth; the main drawback is that every dollar you withdraw in retirement is taxed as ordinary income, and RMDs eventually force withdrawals.

Pros:

• Potential tax deduction in the year you contribute, lowering your current taxable income
• Tax-deferred compound growth — no annual tax drag on dividends or gains
• No income limit on eligibility to contribute
• Useful if you expect to be in a lower tax bracket in retirement than you are now

Cons:

• Withdrawals are taxed as ordinary income, not the lower capital gains rate
• Required Minimum Distributions force you to withdraw (and pay tax on) money starting at a set age, even if you don't need it
• Early withdrawals before age 59½ generally trigger a 10% penalty on top of ordinary income tax, with limited exceptions
• If you don't qualify for the deduction (due to income and workplace coverage), you lose one of the account's biggest advantages

How Does a Roth IRA Work?

A Roth IRA is funded with after-tax dollars, meaning you get no upfront deduction, but your investments grow tax-free and qualified withdrawals in retirement are entirely tax-free.

The mechanics:

1. You contribute after-tax dollars. There's no tax deduction for Roth contributions.
2. Your money grows tax-free. Dividends, interest, and capital gains inside the account are never taxed as long as the rules are followed.
3. Qualified withdrawals are tax-free. Once you're 59½ and have held the account at least five years, withdrawals of both contributions and earnings come out with zero tax owed.
4. No RMDs during your lifetime. Roth IRAs are not subject to Required Minimum Distributions for the original owner, which gives you more flexibility and estate-planning value.

Unlike a Traditional IRA, Roth IRA eligibility is subject to income limits. For 2026, single and head-of-household filers can make a full contribution with modified adjusted gross income (MAGI) below $153,000, phasing out completely at $168,000. Married couples filing jointly can contribute fully below $242,000 MAGI, phasing out at $252,000.

What Are the Pros and Cons of a Roth IRA?

The main advantage of a Roth IRA is tax-free growth and tax-free withdrawals with no RMDs; the main drawback is no upfront deduction and income limits that may restrict who can contribute directly.

Pros:

• Tax-free growth and tax-free qualified withdrawals in retirement
• No Required Minimum Distributions during your lifetime — more control and better for legacy/estate planning
• Contributions (not earnings) can be withdrawn at any time, tax- and penalty-free, offering more flexibility
• Especially valuable if you expect to be in the same or a higher tax bracket in retirement

Cons:

• No upfront tax deduction, so it doesn't reduce your current-year taxable income
• Income limits can restrict or eliminate your ability to contribute directly (though strategies like a "backdoor Roth" may apply — a conversation to have with a fiduciary advisor)
• Five-year holding rule can complicate early access to earnings
• Less immediate tax benefit for high earners in their peak-income years

How Do IRAs Compare to a 401(k)?

A 401(k) is an employer-sponsored plan with higher contribution limits and possible employer matching, while an IRA is opened independently, offers a broader range of investment choices, and typically comes with lower account fees.

How Does IRA Taxation Actually Work?

Traditional IRAs defer taxation until withdrawal, taxing distributions as ordinary income; Roth IRAs tax contributions upfront but never tax qualified growth or withdrawals again.

Breaking it down by account type:

Traditional IRA taxation:

• Contributions may be tax-deductible in the year made (subject to income and workplace-plan rules)
• Growth inside the account is tax-deferred — no annual taxes on dividends, interest, or capital gains
• Withdrawals in retirement are taxed as ordinary income, at whatever your tax rate is that year
• Withdrawals before age 59½ typically incur a 10% early withdrawal penalty in addition to ordinary income tax
• RMDs begin at the applicable age under current law, forcing taxable withdrawals

Roth IRA taxation:

• Contributions are made with after-tax dollars — no deduction now
• Growth inside the account is entirely tax-free
• Qualified withdrawals (after age 59½ and the five-year rule is met) are 100% tax-free — contributions and earnings alike
• Contributions can be withdrawn at any time without tax or penalty, since you already paid tax on that money
• Withdrawing earnings early (before 59½ or before the five-year rule is met) can trigger both income tax and a 10% penalty on the earnings portion

The core tax question to ask yourself: Do you think your tax rate will be higher or lower in retirement than it is right now? If lower, the upfront deduction of a Traditional IRA may be more valuable. If higher — or you simply want tax certainty and flexibility later — the Roth's tax-free withdrawals may be worth more over time.

Frequently Asked Questions

What is the difference between a Traditional IRA and a Roth IRA?

A Traditional IRA is funded with pre-tax dollars and taxed on withdrawal, while a Roth IRA is funded with after-tax dollars and offers tax-free withdrawals in retirement. The core trade-off is a tax break now (Traditional) versus a tax break later (Roth).

How much can I contribute to an IRA in 2026?

For 2026, the combined contribution limit across all your Traditional and Roth IRAs is $7,500, or $8,600 if you're age 50 or older. This limit applies across all your IRAs combined, not per account.

Can I contribute to both a Traditional IRA and a Roth IRA in the same year?

Yes, but your combined contributions across both accounts cannot exceed the annual limit ($7,500, or $8,600 if 50+). You could, for example, split $3,750 into each account.

Is there an income limit for contributing to an IRA?

Traditional IRAs have no income limit on contributions, though tax deductibility may be limited if you or your spouse have a workplace plan. Roth IRAs do have income limits: for 2026, single filers phase out between $153,000 and $168,000 MAGI, and joint filers phase out between $242,000 and $252,000 MAGI.

Can I have an IRA and a 401(k) at the same time?

Yes. IRAs and 401(k)s are not mutually exclusive, and many savers contribute to both to maximize their overall tax-advantaged savings and take advantage of an employer match while also benefiting from an IRA's broader investment choices.

What happens if I withdraw from my IRA early?

Withdrawals before age 59½ generally trigger a 10% early withdrawal penalty in addition to any income tax owed, though there are exceptions (such as certain first-time home purchases, qualified education expenses, or financial hardship). Roth IRA contributions (not earnings) can be withdrawn early without penalty since they were already taxed.

Do Roth IRAs have Required Minimum Distributions (RMDs)?

No. Roth IRAs are not subject to RMDs during the original account owner's lifetime, which is one of the key advantages over a Traditional IRA for estate and legacy planning.

Which is better, a Traditional IRA or a Roth IRA?

Neither account is universally "better" — it depends on whether you expect to be in a higher or lower tax bracket in retirement compared to today. A fee-only fiduciary advisor can help you model both scenarios against your specific income, savings goals, and time horizon.
