What a Roth IRA actually is and how it works

A Roth IRA is a retirement savings account where you put in money that has already been taxed, and then the money grows tax-free. When you withdraw it in retirement — after age 59½ — you pay no tax on the growth. That's the core trade-off: you don't get a tax break when you deposit, but you get one when you take the money out decades later.

The account itself is just a container. You open it at a bank, credit union, or brokerage firm, and then you decide what to put inside it — usually stocks, bonds, mutual funds, or target-date funds. The institution holds the account and keeps track of your balance. You control what investments go in it, or you can choose a simple option like a target-date fund that adjusts itself as you get older.

The IRS sets limits on how much you can deposit each year. For 2024, that limit is $7,000 if you're under 50, and $8,000 if you're 50 or older. You can only deposit money you actually earned — from a job, self-employment, or other income — not from investments or gifts. If you earn less than the limit, you can only deposit what you earned that year.

Key Takeaways

  • You can open a Roth IRA at a bank, credit union, or brokerage by filling out an application and providing your Social Security number and basic income information.
  • You fund the account by transferring money from your checking or savings account, and you can deposit up to $7,000 per year (or $8,000 if you're 50 or older) as long as you earned that much income.
  • Your income determines whether you can make the full deposit — if you earn over a certain threshold, your deposit limit phases out, and the threshold varies by filing status.
  • Once the money is in the account, you choose what to invest it in, and those investments grow tax-free until you withdraw them in retirement.
  • You can withdraw your own deposits (not the growth) at any time without penalty, but withdrawing growth before 59½ usually costs you a 10 percent penalty plus income tax.

Where to open a Roth IRA and what you'll need

You can open a Roth IRA at almost any financial institution — a bank, credit union, or brokerage firm. Banks and credit unions typically offer simpler options with lower investment choices, often limited to savings accounts or CDs. Brokerages like Fidelity, Vanguard, Charles Schwab, and E-Trade offer thousands of investment options but require you to make your own choices or pick a target-date fund.

To open an account, you'll need to provide your Social Security number, date of birth, address, and employment information. The institution will ask your income level so they can verify you're under the income limit for that year. You'll sign an application — usually online — and the account opens within a few days. Some institutions require a minimum deposit to open, often $0 to $500, though many have no minimum.

Once the account is open, you transfer money into it from a checking or savings account you already have. This is a normal bank transfer, the same way you might move money between your own accounts. The money arrives in your Roth IRA within one to three business days, and then it sits there until you decide what to invest it in.

Income limits and how they affect your deposit

The IRS restricts who can make a full Roth IRA deposit based on income. The limit depends on your filing status — whether you file taxes as single, married filing jointly, or another status — and it changes each year. For 2024, if you file as single, the limit begins to phase out at $146,000 in income, and you cannot make any deposit if you earn $161,000 or more. If you file as married filing jointly, those numbers are $230,000 and $240,000.

If your income falls in the phase-out range, you can make a partial deposit. For example, if you're single and earn $150,000, you're in the phase-out range, so you can deposit less than the full $7,000. The exact amount requires a calculation, but your brokerage or bank can do this for you when you deposit.

If your income exceeds the limit entirely, you cannot make a direct deposit to a Roth IRA. However, a strategy called a "backdoor Roth" exists for higher earners — you deposit money into a traditional IRA first, then convert it to a Roth. This is legal but has tax complications, so consult a tax professional if your income is above the limit.

Choosing what to invest your money in

Once your money is in the Roth IRA, you need to tell the institution what to do with it. If you leave it sitting in cash, it earns almost nothing. You have to actively choose an investment, or the account may default to a money market fund or sweep account that pays very little.

The simplest choice for most people is a target-date fund. You pick the year you plan to retire — say, 2055 — and the fund automatically holds a mix of stocks and bonds that shifts toward bonds as you get closer to that year. You don't have to rebalance or think about it. Target-date funds exist at every brokerage and most banks.

If you want more control, you can build your own mix of individual funds or stocks. A common beginner approach is to split money between a total stock market index fund and a total bond market index fund, adjusting the split based on your age and risk tolerance. Younger investors often hold more stocks; older investors hold more bonds.

You can change your investments anytime without penalty. If you move money from one fund to another within the same Roth IRA, it's not a taxable event — the IRS doesn't care. This is different from moving money out of the account entirely, which has tax and penalty rules.

How much you can deposit each year and when

You can deposit up to $7,000 per year if you're under 50, or $8,000 if you're 50 or older. You don't have to deposit it all at once. You can deposit $583 per month, or $1,750 per quarter, or any other schedule that adds up to your limit. Many people set up automatic monthly transfers so they don't have to think about it.

The deposit deadline is the tax filing deadline for that year — April 15 of the following year. If you want to deposit for 2024, you have until April 15, 2025. The institution will ask you which year you're depositing for, so you can deposit for 2024 in January 2025 if you want, as long as you do it before April 15.

If you earn less than the annual limit, you can only deposit what you earned. If you earned $4,000 that year, you can deposit $4,000 maximum, even if you're under 50 and the limit is $7,000. You cannot borrow against future earnings to deposit more now.

Withdrawing money from your Roth IRA

One advantage of a Roth IRA is that you can withdraw the money you deposited — called your contributions — at any time without penalty or tax. If you deposited $5,000 and it grew to $6,000, you can withdraw the $5,000 contribution anytime. The $1,000 in growth stays in the account.

Withdrawing the growth before age 59½ is different. If you take out the earnings, you owe income tax on them plus a 10 percent penalty. There are a few exceptions — if you're disabled, a first-time homebuyer (up to $10,000 lifetime), or facing a may have access to hardship, the penalty may not apply. But the income tax still does unless you meet a specific exception.

After age 59½, you can withdraw both contributions and growth tax-free and penalty-free, as long as the account has been open for at least five years. The five-year rule is separate from the age rule — both have to be met. If you open a Roth at age 58, you can't withdraw growth tax-free until age 63, even though you're over 59½.

The difference between a Roth IRA and other retirement accounts

A traditional IRA works in reverse: you get a tax break when you deposit (if you meet income limits), but you pay tax when you withdraw in retirement. A 401(k) is an employer plan, not something you open yourself, and it usually offers a match from your employer. A SEP IRA or Solo 401(k) is for self-employed people who want to save more than a Roth IRA allows.

The Roth IRA is best if you expect to be in a higher tax bracket in retirement, or if you want flexibility — you can withdraw contributions anytime, and there's no required withdrawal age. The traditional IRA is better if you want a tax break now and expect to be in a lower bracket later. A 401(k) is best if your employer offers a match, because that's assistance programs.

You can have both a Roth IRA and a traditional IRA, but your total deposits to both accounts cannot exceed the annual limit. If you deposit $4,000 to a Roth, you can only deposit $3,000 to a traditional IRA that year.

Frequently Asked Questions

Can I open a Roth IRA if I'm self-employed or a freelancer?

Yes, as long as you have earned income from your business. The income limit still applies, and you can only deposit what you earned. If you want to save more than the Roth IRA limit allows, you can also open a SEP IRA or Solo 401(k), which have much higher limits for self-employed people.

What happens if I deposit more than the limit by accident?

The excess deposit is subject to a 6 percent penalty each year it stays in the account. You should withdraw the excess and any growth on it as soon as you notice. Your brokerage can help you calculate how much to withdraw. If you catch it before filing taxes, you can often fix it without major penalties.

Can I move money from a traditional IRA to a Roth IRA?

Yes, through a process called a conversion. You withdraw money from the traditional IRA and deposit it into a Roth within 60 days. You'll owe income tax on the amount converted, but the money is then in a Roth and grows tax-free. This is useful if your income drops in a particular year.

Do I have to start withdrawing money at a certain age?

No. Unlike a traditional IRA, a Roth IRA has no required withdrawal age. You can leave the money in the account for your entire life and pass it to heirs. This makes a Roth useful for leaving money to family members, since they inherit the tax-free growth.

What if my employer offers a 401(k) — should I still open a Roth IRA?

If your employer matches contributions to the 401(k), contribute enough to get the full match first — that's assistance programs. After that, a Roth IRA is often a good next step because of its flexibility and lower fees. You can have both accounts at the same time.
