What an IRA account does and how the money grows

An IRA is a savings account the government created specifically for retirement. You put money in, that money grows over time through interest or investments, and you can withdraw it after age 59½ without a penalty. The main advantage is tax treatment: depending on which type of IRA you have, either your contributions reduce your taxes now, or your withdrawals stay tax-free later. The account itself is just a container—your bank, brokerage, or credit union holds it and lets you decide what to invest the money in.

The growth happens because your money sits in the account earning returns. If you put $5,000 in an IRA and it grows at 5% per year, after 10 years you have roughly $8,150 without adding another dollar. That growth compounds—meaning you earn returns on your returns—which is why starting early matters. The longer the money stays in the account, the more it grows.

You control how the money is invested. Most IRAs let you choose between stocks, bonds, mutual funds, or target-date funds (funds that automatically shift from aggressive to conservative as you near retirement). Some people pick individual stocks; others use a simple index fund. The account custodian—your bank or brokerage—doesn't decide for you unless you ask them to manage it.

Key Takeaways

  • An IRA is a retirement savings account where your money grows tax-advantaged, meaning you either pay less tax now or pay no tax on withdrawals later.
  • You can withdraw money penalty-free starting at age 59½; withdrawals before that age usually trigger a 10% penalty plus income tax.
  • You choose what to invest the money in—stocks, bonds, funds—and the account custodian (your bank or brokerage) holds it for you.
  • Contribution limits change yearly and depend on your age and income; the IRS publishes the current year's limit on its website.
  • The two main types are Traditional (contributions may reduce your taxes now) and Roth (withdrawals are tax-free later), and the choice depends on whether you want a tax break today or in retirement.

Traditional IRA vs. Roth IRA: which type to choose

A Traditional IRA lets you deduct your contributions from your income taxes in the year you make them—if you earn $50,000 and contribute $6,500, you report $43,500 as taxable income. You pay no tax on the growth while the money sits in the account. When you withdraw in retirement, you pay income tax on the full amount you take out. This works well if you expect to be in a lower tax bracket in retirement than you are now.

A Roth IRA works the opposite way. You contribute money that has already been taxed (no deduction now), but the growth and all withdrawals are tax-free forever. You never pay tax on the money again, even in retirement. This works well if you expect to be in a higher tax bracket later, or if you simply want certainty—you know exactly what you'll owe in taxes because the answer is zero.

Income limits apply to Roth contributions. If you earn above a certain threshold (the limit varies by year and filing status), you cannot contribute to a Roth directly. Traditional IRAs have no income limit, but if you or your spouse has a workplace retirement plan, the tax deduction phases out at higher incomes. Check the IRS website for the current year's limits before deciding.

Many people split the difference: they contribute to a Traditional IRA for the tax break now, and also fund a Roth if they have room in their budget. There is no rule against having both types at the same time, as long as your total contributions across all IRAs do not exceed the annual limit.

Contribution limits and how much you can add each year

The IRS sets an annual contribution limit—the maximum you can add to an IRA in a single year. This limit changes most years and is higher if you are age 50 or older. For 2024, the limit is $7,000 for people under 50 and $8,000 for people 50 and up. The IRS announces the next year's limit in October, so you can plan ahead.

You can contribute up to the limit as long as you have earned income that year. If you earned $3,000 from a job, you can only contribute $3,000 to an IRA, even if the limit is higher. Self-employed people can contribute based on their net business income. If you are married and your spouse has no income, you can fund a spousal IRA in their name using your household income, as long as your combined contributions do not exceed the limit.

You can contribute at any time during the year or up until the tax filing deadline the following year (usually April 15). Many people wait until tax time to see how much they can afford, or to understand their tax situation for that year. There is no penalty for contributing late, as long as you do it before the deadline.

How withdrawals work and when you can take money out

You can withdraw money from your IRA anytime, but the tax and penalty consequences depend on your age and the type of account. If you are under 59½ and withdraw from a Traditional IRA, you owe income tax on the amount plus a 10% early withdrawal penalty. If you withdraw $10,000, you might owe $2,000 in taxes and penalties combined, depending on your tax bracket.

Roth IRAs have different rules. You can withdraw your contributions (the money you put in) anytime without tax or penalty. You can only withdraw the growth and earnings before age 59½ if you meet specific exceptions, such as a first-time home purchase (up to $10,000 lifetime) or a may have access to education expense. If you do not meet an exception, you pay tax and the 10% penalty on the earnings portion.

At age 73, you must begin taking required minimum distributions (RMDs) from Traditional IRAs. The IRS calculates how much you must withdraw each year based on your age and account balance. If you do not take the full amount, you owe a 25% penalty on the shortfall (reduced to 10% if you correct it within two years). Roth IRAs have no RMD requirement during your lifetime, which is one reason some people prefer them.

A few exceptions let you withdraw early without the 10% penalty: disability, medical expenses above 7.5% of your income, health insurance premiums while unemployed, and a few others. You still owe income tax on the withdrawal, but the penalty is waived. The IRS website lists all exceptions in Publication 590-B.

Where to open an IRA and what custodians offer

You can open an IRA at a bank, credit union, brokerage firm, or robo-advisor. Banks typically offer IRAs invested in savings accounts or CDs, which earn a fixed interest rate but grow slowly. Brokerages like Fidelity, Vanguard, and Charles Schwab let you invest in stocks, bonds, and funds with more control and usually lower fees. Robo-advisors like Betterment or Wealthfront manage the investments for you automatically based on your age and risk tolerance.

Most custodians charge no fee to open or maintain an IRA, but some charge annual account fees ($25 to $50) if your balance is below a certain amount. Investment fees vary: index funds typically cost 0.03% to 0.20% per year, while actively managed funds or robo-advisor services cost more. Compare fees before opening, because small differences compound over decades.

You can move money between custodians without penalty through a rollover or transfer. A rollover means you withdraw the money and deposit it elsewhere within 60 days; a transfer means the custodians move it directly. A transfer is simpler and avoids the 60-day window, so it is the safer choice. You can do one rollover per year per IRA type, but unlimited transfers.

How IRAs fit into a broader retirement plan

An IRA is one tool among several. If your employer offers a 401(k) or 403(b), that is usually the first place to save because employers often match contributions (assistance programs). Max out the match before funding an IRA. If you are self-employed, a Solo 401(k) or SEP-IRA lets you save much more than an IRA allows—up to $69,000 per year versus $7,000.

Many people use both: they contribute to a workplace plan at work, then fund an IRA with additional savings. This spreads your money across accounts with different tax treatments and investment options. Some people use a Traditional IRA for the tax deduction, a Roth for tax-free growth, and a 401(k) for employer matching—all at the same time.

An IRA is not a complete retirement plan on its own. It is a container for long-term savings. You still need to decide how much to save overall, how to invest it, and when to start withdrawing. Many people work with a financial planner to build a full picture, but you can also use online calculators to estimate how much you need to save to reach your retirement goal.

Common mistakes people make with IRAs

The most common mistake is not starting early. If you wait until age 40 to open an IRA, you miss 20 years of compound growth. Someone who contributes $6,500 per year from age 25 to 65 ends up with roughly $1 million (assuming 7% annual returns), while someone who starts at 45 ends up with roughly $300,000. Time is the most powerful tool in an IRA.

Another mistake is choosing the wrong investment. Some people put IRA money in a savings account earning 0.01% when they could earn 4% to 5% in a money market fund or bond fund. Others panic during market downturns and sell stocks at a loss, locking in losses instead of waiting for recovery. Your investment choice matters as much as the account type.

A third mistake is withdrawing early without understanding the penalty. Many people raid their IRA for a down payment, medical bill, or job loss, not realizing they will owe 10% plus income tax. The money is yours, but the cost of taking it out early is high. Explore other options—a home loan, a payment plan, a personal loan—before touching retirement savings.

Finally, some people contribute to both a Traditional and Roth IRA without tracking their total. If you contribute $4,000 to a Traditional IRA and $4,000 to a Roth, you have hit the $8,000 limit and cannot add more that year. The IRS tracks this across all your IRAs, so you must keep your own records too.

Frequently Asked Questions

Can I have more than one IRA?

Yes. You can have multiple Traditional IRAs, multiple Roth IRAs, or both types at the same time. However, your total contributions across all IRAs cannot exceed the annual limit. If you have three Traditional IRAs and contribute $3,000 to each, you have exceeded the limit and owe a penalty on the excess. Track your contributions across all accounts.

What happens to my IRA if I change jobs?

Your IRA stays yours and does not change. If your new employer offers a 401(k), you can contribute to both the 401(k) and your IRA (up to their separate limits). You can also roll over your old employer's 401(k) into your IRA if you leave the job, which consolidates your retirement savings in one place.

Can I withdraw money from my IRA to buy a house?

You can withdraw up to $10,000 from a Roth IRA for a first-time home purchase without the 10% penalty, though you still owe income tax on any earnings. From a Traditional IRA, you owe both tax and penalty unless you meet another exception. Consider a home loan or down payment assistance program first, because withdrawing from retirement savings reduces the money available later.

What if I inherit an IRA from someone?

The rules depend on your relationship to the person and the type of IRA. Spouses can treat the inherited IRA as their own. Non-spouse beneficiaries must withdraw the entire balance within 10 years (as of 2023 rules). Consult a tax professional or the IRA custodian for guidance, because mistakes can trigger large tax bills.

Do I have to report my IRA on my taxes?

You report IRA contributions and withdrawals on your tax return. If you take a deduction for a Traditional IRA contribution, you claim it on your return. If you withdraw money, the custodian sends you a Form 1099-R, and you report it as income. Roth contributions are not deductible, and may have access to Roth withdrawals are not reported as income, but the custodian still sends a Form 1099-R for record-keeping.
