An Individual Retirement Account (IRA) is a US tax-advantaged account you open yourself, through a bank or brokerage, to save and invest for retirement, separate from any employer-sponsored plan like a 401(k). The IRS describes IRAs as allowing tax-deferred investments to build financial security for retirement. The two main types, Traditional and Roth, differ in exactly when you get the tax benefit: a Traditional IRA typically reduces your taxable income now, while a Roth IRA gives you tax-free withdrawals later.
Not everyone has access to an employer-sponsored retirement plan, and even people who do often want somewhere else to put additional retirement savings. That's exactly the gap an IRA fills: a retirement account you open and control yourself, independent of any employer.
The name itself explains the core idea, "Individual" because it belongs to you personally rather than being tied to a job, and "Retirement Account" because it comes with tax rules specifically designed to encourage long-term retirement savings rather than everyday spending.
This guide covers how an IRA works, the difference between a Traditional and a Roth IRA, who each tends to suit best, and how an IRA compares to an employer-sponsored plan. It's one piece of the broader picture of how much you actually need to retire, alongside how your retirement savings compare by age.
You open an IRA through a bank, brokerage, or investment firm, fund it with contributions, and choose how to invest the money, stocks, bonds, funds, and other assets are typically all available, unlike many employer plans that limit you to a preset menu of options.
In exchange for tax advantages, IRAs come with rules about when you can access the money. Withdrawals before a set retirement age generally trigger a tax penalty, on top of any income tax owed, which is the tradeoff for the account's tax-favored treatment.
IRAs come with an annual contribution limit, a cap on how much can be added across all of a person's IRAs combined in a given year. That limit is set by the IRS and has historically been adjusted periodically over time, so it's worth checking the current figure directly with the IRS or a brokerage rather than relying on a specific number that may be out of date.
Savers above a certain age are typically allowed an additional "catch-up" contribution on top of the standard limit, recognizing that people closer to retirement may want to accelerate their savings. Contribution limits, and in some cases eligibility to contribute at all, can also depend on income level, particularly for Roth IRAs.
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| When you get the tax break | Now, contributions may reduce your taxable income today | Later, qualified withdrawals in retirement are tax-free |
| How contributions are taxed | Often tax-deductible, depending on income and other coverage | Made with after-tax income, no upfront deduction |
| How withdrawals are taxed | Taxed as ordinary income in retirement | Not taxed, since tax was already paid on the way in |
| Best fit | Often suits people expecting a lower tax rate in retirement | Often suits people expecting a similar or higher tax rate later |
Neither option is universally better, it depends heavily on your current income, your expected income in retirement, and how those tax rates compare. Many people end up holding both types over their working life.
Unlike many employer-sponsored plans, which limit investment choices to a preset menu of funds, an IRA opened through a brokerage typically allows access to a much broader range of assets: individual stocks, bonds, mutual funds, and index funds are all commonly available.
That flexibility is one of the reasons people use an IRA even when they already have an employer plan, it opens up investment options, like a specific index fund tracking a particular market, that a 401(k)'s limited fund menu might not include.
An IRA and a 401(k) both offer tax-advantaged retirement savings, but they differ in a few important ways. A 401(k) is sponsored by an employer, often comes with a matching contribution, and typically has a higher annual contribution limit. An IRA is opened independently, usually has a lower contribution limit, but generally offers a far wider range of investment choices.
They aren't mutually exclusive. Many people contribute enough to a 401(k) to capture any employer match, then use an IRA for additional retirement savings beyond that, though the right combination depends on each person's own plan options, income, and goals.
Beyond Traditional and Roth, a few other IRA variants exist, mainly aimed at self-employed people and small business owners:
Both work within the same broad Traditional-style tax treatment as a standard IRA, contributions are typically made pre-tax, with withdrawals taxed later, but with different contribution limits and eligibility rules suited to self-employed and small-business situations.
Anyone without access to an employer plan. Self-employed individuals, freelancers, and employees whose employer doesn't offer a 401(k) can still get tax-advantaged retirement savings through an IRA.
Anyone who's maxed out their employer plan. An IRA is a natural next step for additional tax-advantaged savings once a 401(k) contribution is maxed out for the year.
Anyone who wants more investment control. IRAs typically offer a much broader selection of investments than a typical employer 401(k) menu, which appeals to people who want more control over exactly what they're invested in.
Anyone consolidating old retirement accounts. People who've changed jobs several times often end up with multiple old 401(k) accounts scattered across former employers. Rolling those into a single IRA is a common way to bring everything under one roof, with one set of investment choices and one place to track progress, rather than managing several separate accounts with different rules and fund menus.
An IRA is one account type among several that can make up a person's overall retirement savings, alongside an employer plan, taxable investment accounts, and, for some, other tax-advantaged vehicles. None of these exist in isolation, how much ends up in an IRA relative to everything else is part of the larger question of how much someone actually needs to retire and how their savings compare to typical benchmarks at their age.
Because IRAs are opened and managed independently of any employer, they also tend to be the account type that follows someone across an entire career, surviving job changes in a way an employer-sponsored plan by itself doesn't, which is part of why they're often treated as a long-term core piece of a retirement plan rather than a secondary account.

What does IRA stand for?
Individual Retirement Account (sometimes called an Individual Retirement Arrangement). It's a tax-advantaged account opened by an individual, rather than provided through an employer.
What's the difference between a Traditional and a Roth IRA?
A Traditional IRA often gives you a tax deduction now, with withdrawals taxed as ordinary income in retirement. A Roth IRA offers no upfront deduction, but qualified withdrawals in retirement are tax-free.
Can I have both a 401(k) and an IRA?
Yes. They're not mutually exclusive, many people contribute to an employer 401(k) (especially up to any employer match) and also contribute to an IRA for additional retirement savings.
Is there a penalty for withdrawing from an IRA early?
Generally yes. Withdrawing funds before the account's designated retirement age typically triggers a tax penalty in addition to any income tax owed, though certain exceptions exist depending on the circumstances.
How much can I contribute to an IRA each year?
IRAs have an annual contribution limit set by the IRS, which is adjusted periodically and combines across all of a person's IRAs. Those closer to retirement age are typically allowed an additional catch-up contribution on top of the standard limit.
Can self-employed people use an IRA?
Yes. Beyond a standard Traditional or Roth IRA, self-employed individuals and small business owners often have access to variants like a SEP IRA or SIMPLE IRA, which generally allow higher contribution limits suited to that situation.
What can I invest in through an IRA?
It depends on where the IRA is opened, but brokerage-based IRAs commonly offer a broad range of investments, including individual stocks, bonds, mutual funds, and index funds, typically far more choice than a standard employer plan's fund menu.
