What Is an IRA? How It Works and Who It's For

An IRA is a retirement savings account with built-in tax advantages. The key thing to understand upfront: an IRA is not a specific investment — it is a container that holds investments. You open one at a brokerage, bank, or robo-advisor, choose what to put inside it, and the account grows over time. What separates it from a regular brokerage account is the tax treatment the IRS gives it.

The word "Individual" matters here. An IRA belongs to one person — unlike a joint bank account, IRAs cannot be co-owned. You are the sole account holder, which means the investment decisions, contribution timing, and withdrawal strategy are entirely yours to manage.

Why IRAs exist

Congress created IRAs to give everyday people a way to save for retirement outside of an employer-sponsored plan. The idea was straightforward: offer a tax incentive, and more people will put money away for the future. IRAs were designed to complement workplace retirement plans like a 401(k), not replace them. But they are also fully available to people who have no workplace plan at all — freelancers, gig workers, and employees whose employers simply do not offer one.

Most people choosing an IRA are choosing between two types: Traditional and Roth. Both offer tax advantages — they just deliver them at different times.

Traditional IRA

With a Traditional IRA, contributions may be tax-deductible depending on your income and whether you or your spouse has access to a workplace retirement plan. Your money grows tax-deferred, meaning you do not pay taxes on dividends or gains each year. When you withdraw money in retirement, those withdrawals are taxed as ordinary income. The IRS also requires you to start taking money out at age 73 — these are called Required Minimum Distributions, or RMDs.

Roth IRA

A Roth IRA works the other way around. You contribute money you have already paid taxes on — there is no deduction upfront. In exchange, your money grows completely tax-free, and qualified withdrawals in retirement are also tax-free. Roth IRAs have no RMDs during the original account holder's lifetime, which gives you more control over when you take money out. One catch: income limits apply. For 2024, the ability to contribute directly to a Roth IRA phases out at $146,000 for single filers and $230,000 for married couples filing jointly.

How to choose between them

The core question is whether you would rather pay taxes now or later. If you expect your income — and your tax rate — to be higher in retirement than it is today, a Roth tends to make more sense. If you want the tax break now, a Traditional IRA may fit better. Age, current income, and expected retirement income all factor in — the right approach depends on what you are looking for.

Other IRA types worth knowing

• SEP IRA: Built for self-employed people and small business owners. Contribution limits are significantly higher than a standard IRA.
• SIMPLE IRA: An employer-sponsored option designed for small businesses that want to offer a retirement benefit.
• Rollover IRA: Used to move money from a 401(k) or other workplace plan into an IRA when you leave a job — keeps your retirement savings consolidated and under your control.

Opening an IRA takes about 15 minutes online. You will need a Social Security number and a bank account to fund it — there is no employer involvement and no waiting period. Many providers have no minimum to get started, and some let you open an account with as little as $1.

What you can invest in

Once the account is open, you choose what to put inside it. Stocks, bonds, mutual funds, index funds, and ETFs are the most common choices and available at virtually every major brokerage. Some providers also allow REITs and options. A self-directed IRA can hold alternative investments like real estate, though these accounts involve more complexity and cost — they are built for experienced investors with specific needs.

Contribution limits (2024)

• Under 50: $7,000 per year
• 50 or older: $8,000 per year (the extra $1,000 is called a catch-up contribution)
• Limits are per person, not per account — if you hold both a Traditional and a Roth IRA, the combined total across both still cannot exceed $7,000
• You have until the federal tax filing deadline — typically April 15 — to make contributions for the prior tax year

Tax treatment at a glance

• Traditional: Possible deduction now; taxes on withdrawal later
• Roth: No deduction now; tax-free withdrawal later
• Both: Investments grow without being taxed each year on dividends or gains

Early withdrawal rules

Withdrawals before age 59½ generally trigger a 10% penalty plus income taxes on the amount taken out. There are exceptions — a first-time home purchase, higher education expenses, disability, and a handful of others. One useful Roth IRA feature: because Roth contributions are made with after-tax money, you can withdraw the amount you contributed at any time without penalty. Only the earnings are restricted until retirement age.

IRAs were designed to be accessible to anyone with earned income. But certain situations make them especially useful.

People without a workplace retirement plan

Freelancers, gig workers, and employees at companies that do not offer a 401(k) have no automatic payroll-based path to retirement savings. An IRA fills that gap. You open it yourself, fund it on your own schedule, and choose where it lives.

People who want more than a 401(k) offers

Workplace retirement plans often limit your investment choices to a curated menu of mutual funds. An IRA at a major brokerage typically gives you access to a much wider range of investments. A common approach: contribute enough to your 401(k) to capture any employer match, then fund an IRA for additional flexibility and investment choice.

People who have changed jobs

When you leave a job, a Rollover IRA lets you move an old 401(k) into an account you own and control — keeping your retirement savings in one place rather than scattered across former employers.

People building toward tax-free retirement income

Roth IRAs are commonly chosen by younger savers who expect their income and tax rate to rise over time. Locking in tax-free growth now means withdrawals in retirement will not add to taxable income — which matters when you are planning how much you will actually keep from each dollar you withdraw.

IRAs come with a defined set of rules set by the IRS. Understanding the key ones helps you use the account correctly and avoid penalties.

Income limits

• Traditional IRA: Anyone with earned income can contribute. Whether the contribution is tax-deductible depends on your income and whether you or your spouse has a workplace retirement plan.
• Roth IRA: Direct contributions phase out at $146,000 for single filers and $230,000 for married couples filing jointly in 2024. Above those thresholds, the contribution amount is reduced or eliminated.

Contribution deadline

You can make IRA contributions for a given tax year up until the federal tax filing deadline — typically April 15 of the following year. You do not have to contribute all at once; many people contribute monthly throughout the year.

Required Minimum Distributions

Traditional IRA holders must start taking money out at age 73. These Required Minimum Distributions are calculated based on your account balance and life expectancy. Roth IRA holders are not subject to RMDs during their lifetime — the money can stay invested as long as you choose.

Spousal IRA

A spouse who does not have earned income can still contribute to an IRA, as long as the couple files taxes jointly and the working spouse has enough earned income to cover both contributions. This lets a non-working or lower-earning spouse build retirement savings in their own name.
