An IRA lets you save for retirement while cutting your tax bill right now

An Individual Retirement Account (IRA) is a savings account with tax breaks built in. The main advantage is that money you put in either reduces your taxable income this year (traditional IRA) or grows completely tax-free (Roth IRA). That tax break means you keep more of your paycheck and your money compounds without the IRS taking a cut along the way.

Without an IRA, you save money in a regular savings account or brokerage account and pay taxes on every dollar of interest, dividends, or gains you earn. With an IRA, those earnings stay sheltered from federal income tax until you withdraw them—or forever, depending on which type you choose. Over decades, that difference compounds into tens of thousands of dollars more in your pocket.

Key Takeaways

  • A traditional IRA reduces your taxable income in the year you contribute, lowering your tax bill immediately.
  • A Roth IRA lets your money grow tax-free forever, so you owe no federal tax on withdrawals in retirement.
  • Both types protect your savings from annual taxes on interest and investment gains, which accelerates how fast your money grows.
  • IRAs have annual contribution limits (currently $7,000 for most people under 50), so you cannot put unlimited money in, but the tax shelter applies to every dollar you do contribute.

How the tax break works in a traditional IRA

When you contribute to a traditional IRA, that money comes off your taxable income for the year. If you earn $60,000 and contribute $7,000 to a traditional IRA, you only report $53,000 as taxable income. That means you pay federal income tax on $7,000 less, which saves you money depending on your tax bracket.

The money inside the account then grows—through interest, dividends, or investment gains—without triggering taxes each year. You do not pay tax on those earnings until you withdraw the money in retirement. At that point, you pay income tax on the full amount you take out, but by then you may be in a lower tax bracket because you are no longer working.

How the tax break works in a Roth IRA

A Roth IRA works differently. You contribute money that has already been taxed (you do not get a deduction this year), but then your money grows completely tax-free. When you withdraw it in retirement, you owe nothing—no federal income tax on the earnings, no tax on the original contributions.

This matters most if you expect to be in a higher tax bracket in retirement than you are now, or if you simply want to lock in current tax rates and avoid paying more later. A Roth also has no required withdrawals at a certain age, so you can let the money sit and grow for as long as you want.

The compounding advantage over decades

The real power of an IRA is that taxes do not eat into your returns every single year. In a regular taxable account, if you earn $500 in investment gains, you might owe $100 to $150 in taxes depending on your bracket. That $100 to $150 never gets reinvested, so it never compounds. In an IRA, that full $500 stays in the account and compounds the next year.

Over 30 or 40 years, this difference is enormous. A person who saves $7,000 per year in a traditional IRA from age 25 to 65 and earns an average 7% annual return will have roughly $1.4 million at retirement. The same person saving in a taxable account and paying taxes on gains each year will have significantly less, even if they earned the same 7% return, because taxes drained money that could have compounded.

You control when and how much you withdraw

Unlike a 401(k) through your employer, an IRA is yours to manage. You decide how to invest the money—stocks, bonds, mutual funds, or even some alternative investments depending on the IRA provider. You also decide when to withdraw it (with some restrictions on early withdrawals before age 59½).

This flexibility means you are not locked into your employer's investment options or forced to take money out on someone else's schedule. You can adjust your strategy as your life changes, and you keep the account even if you change jobs.

IRAs work alongside employer retirement plans

An IRA is separate from a 401(k) or other workplace retirement plan. You can have both. Many people contribute to their employer's 401(k) to get the company match, then open an IRA for additional tax-sheltered savings. This lets you save more for retirement than either account alone would allow.

If you are self-employed or a freelancer with no employer plan, an IRA becomes even more valuable because it may be your only tax-sheltered retirement savings option (though a SEP-IRA or Solo 401(k) might offer higher limits).

The contribution limits mean you need other savings too

The annual contribution limit for a traditional or Roth IRA is $7,000 for people under age 50 (as of 2024; this amount changes periodically). That is a meaningful advantage, but it also means an IRA alone is not enough to build most people's retirement. You will likely need to save in a 401(k), a taxable brokerage account, or both to reach your retirement goals.

The advantage is that the IRA lets you shelter some of your savings from taxes, making every dollar you do contribute work harder. Combined with other savings, it becomes a core piece of a retirement strategy.

Frequently Asked Questions

Can I have both a traditional IRA and a Roth IRA at the same time?

Yes. You can contribute to both in the same year, but your combined contributions cannot exceed the annual limit ($7,000 for most people under 50). Many people use both: a traditional IRA for the immediate tax deduction and a Roth for tax-free growth later.

What happens if I withdraw money from my IRA before retirement?

You generally owe income tax on the withdrawal plus a 10% penalty if you are under 59½. Some exceptions exist—first-time home purchase, medical expenses, and a few others—but early withdrawal usually costs you. This is why an IRA works best as long-term retirement savings, not emergency money.

Do I have to earn income to open an IRA?

Yes. You must have earned income (wages, self-employment income, or taxable compensation) in the year you contribute. You cannot open an IRA and contribute if you had no income that year, though a spouse with no income can sometimes contribute if their spouse earned income.

Is there an income limit for contributing to an IRA?

For a Roth IRA, yes—your income must be below a certain threshold to contribute directly. For a traditional IRA, there is no income limit to contribute, but the tax deduction phases out if you have high income and access to a workplace retirement plan. Check the current limits with the IRS or your tax preparer.

How much should I contribute to an IRA each year?

That depends on your income, expenses, and retirement goals. Many financial advisors suggest saving 10% to 15% of your gross income across all retirement accounts. If you can afford the full $7,000 annual limit, that is a strong start, but even smaller contributions build wealth over time because of the tax shelter and compounding.
