An IRA, or individual retirement account, is a tax-advantaged account that helps you save and invest for retirement. IRAs provide tax advantages for retirement savings, and these accounts are designed to help individuals build long-term financial security.

IRAs matter because they can help your money grow more efficiently than it would in a regular taxable account. IRAs held $19.2 trillion in assets at the end of the fourth quarter of 2025, which shows how central they are to retirement planning in the U.S.

What Is an IRA?

An IRA is a retirement account you open for yourself through a bank, brokerage or other financial institution. You contribute money to it, invest that money and let it grow over time with tax advantages. An IRA provides tax advantages for retirement savings, and notes that several types are available, including traditional, Roth, SEP and SIMPLE IRAs.

In simple terms, an IRA helps you save for retirement while giving you tax benefits now or later, depending on the type you choose.

Tip: An IRA is not the investment itself. It is the account that holds your investments, which may include stocks, bonds, mutual funds and ETFs.

How Does an IRA Work?

An IRA works by letting you contribute money each year, invest those funds and benefit from special tax treatment. In a traditional IRA, contributions may be deductible and growth is tax-deferred. In a Roth IRA, contributions are made with after-tax dollars, but qualified withdrawals in retirement are tax-free.

You generally open the account with a provider, choose your investments and add money over time. You can usually contribute to an IRA for a given tax year until the tax-filing deadline of the following year.

Why Do People Open IRAs?

People open IRAs because they want a dedicated retirement account with tax advantages and flexible investment options. They can be especially useful if you don’t have a workplace retirement plan, or if you already have one and want another way to save. IRAs provide tax incentives that help people build retirement security.

They are also widely used. In mid-2024, 44% of U.S. households owned IRAs, according to research from the Investment Company Institute.

What Are the Main Types of IRAs?

The four main IRA types most readers need to know are:

• Traditional IRA
• Roth IRA
• SEP IRA
• SIMPLE IRA

Traditional IRA

A traditional IRA may let you deduct contributions now, depending on your income and whether you’re covered by a retirement plan at work. Your investments grow tax-deferred, and withdrawals in retirement are generally taxed as ordinary income.

Roth IRA

A Roth IRA is funded with after-tax dollars, so you don’t get a deduction up front. The tradeoff is that qualified withdrawals in retirement are tax-free, and Roth IRAs don’t have lifetime required minimum distributions for the original owner.

SEP IRA

A SEP IRA is generally used by self-employed people and small-business owners. It allows employer-only contributions and much higher contribution limits than a traditional or Roth IRA.

SIMPLE IRA

A SIMPLE IRA is a retirement plan often used by small businesses. It allows employee contributions and requires employer contributions, which makes it more similar to a workplace plan than a personal IRA.

What Is the IRA Contribution Limit for 2026?

For 2026, the IRS says you can contribute up to $7,500 across all of your traditional and Roth IRAs combined, or $8,600 if you are age 50 or older. That means the annual limit is shared across your traditional and Roth IRAs. If you put $4,000 into a traditional IRA, you would have $3,500 left for a Roth IRA in 2026 if you are under 50.

Key Insight: The annual IRA limit applies across your traditional and Roth IRAs combined, not to each account separately.

Who Can Open an IRA?

Most people with earned income can open a traditional or Roth IRA. A non-working spouse may also be able to contribute through a spousal IRA if the couple meets IRS rules. SEP and SIMPLE IRAs are generally tied to self-employment or small-business arrangements.

The more important question is often not whether you can open an IRA, but whether you qualify for the tax benefits or Roth contribution rules attached to it.

Can Anyone Contribute to a Roth IRA?

Not everyone can make the full Roth IRA contribution because income limits apply. For 2026, the IRS says the Roth IRA income phaseout range is:

• $153,000 to $168,000 for single filers and heads of household
• $242,000 to $252,000 for married couples filing jointly

If your income falls inside those ranges, you may be able to make only a reduced contribution. If it is above the top of the range, you can’t contribute directly to a Roth IRA for that year.

What Can You Invest in Inside an IRA?

IRAs can hold a wide range of investments. Investor.gov says IRA providers typically offer choices such as mutual funds, and many IRAs can also hold stocks, bonds and ETFs, depending on the provider.

Common IRA investments include:

• Stocks
• Bonds
• Mutual funds
• ETFs
• Target-date funds
• CDs in some IRA setups

What Are the Biggest Benefits of an IRA?

The biggest benefit of an IRA is the tax advantage. But that’s not the only reason people use them.

Main IRA Benefits

• Potential tax deduction now with a traditional IRA
• Tax-free qualified withdrawals later with a Roth IRA
• Tax-advantaged investment growth
• Wide investment flexibility
• A dedicated account built specifically for retirement savings

An IRA can be one of the simplest ways to start investing for retirement if you don’t have a 401(k), and it can still be useful if you do.

What Are the Downsides of an IRA?

IRAs are powerful, but they’re not perfect.

Main IRA Drawbacks

• Annual contribution limits are lower than many 401(k) plans
• Roth IRAs have income limits
• Early withdrawals may trigger taxes and penalties
• Traditional IRAs generally require minimum distributions later in life
• Deductibility rules can get complicated if you have a workplace plan

The IRS says early withdrawals before age 59½ may trigger a 10% additional tax, with certain exceptions.

IRA vs. 401(k): What’s the Difference?

An IRA is an individual account you open yourself. A 401(k) is usually a workplace retirement plan sponsored by an employer. IRAs generally give you more provider flexibility, while 401(k)s often allow higher annual contributions and may include employer matching.

For many people, using both can be a smart strategy if their budget allows.

How Do You Open an IRA?

Opening an IRA is usually straightforward.

Basic Steps

1. Choose the type of IRA you want.
2. Pick a provider, such as a bank, brokerage or robo-advisor.
3. Open the account and verify your identity.
4. Fund the account.
5. Choose your investments.

Tip: Before opening an IRA, compare investment choices, annual fees, trading costs, account minimums and customer support. A good IRA is not just about tax rules. It is also about how easy the account is to use.

Who Should Consider an IRA?

An IRA can make sense if you:

• want a tax-advantaged way to save for retirement
• don’t have a retirement plan at work
• want to supplement a 401(k)
• are self-employed and want to compare IRA-based retirement options
• want more investment flexibility than some employer plans offer

Final Take to GO

An IRA is a tax-advantaged retirement account that helps individuals save and invest for the future. Traditional IRAs may offer upfront tax benefits, while Roth IRAs can offer tax-free withdrawals later. SEP and SIMPLE IRAs expand the options for self-employed people and small businesses.

The best IRA for you depends on your income, tax situation and retirement goals. But if you want a flexible, widely used retirement account with meaningful tax benefits, an IRA is one of the most important tools to understand.
