An IRA and a mutual fund are not the same thing — they serve different purposes

An IRA (Individual Retirement Account) is a type of account you open at a bank or brokerage to save for retirement. A mutual fund is an investment product you can buy inside that account. Think of an IRA as the container and a mutual fund as one of the things you can put in it. You can hold mutual funds inside an IRA, but the IRA itself is not a mutual fund.

The confusion happens because both involve money and investing, but they work in completely different ways. An IRA is defined by tax rules and withdrawal restrictions set by the government. A mutual fund is defined by how the money is invested — a professional manager pools money from many investors and buys stocks, bonds, or other securities with it. You could put that mutual fund inside your IRA, or you could buy it in a regular taxable account instead.

Key Takeaways

  • An IRA is a retirement savings account with tax advantages and rules about when you can withdraw money; a mutual fund is an investment product that pools money from many investors.
  • You can hold mutual funds inside an IRA, but you can also hold individual stocks, bonds, money market funds, or cash inside an IRA instead.
  • An IRA is opened at a bank or brokerage and is yours alone; a mutual fund is managed by a professional fund manager who buys and sells securities on behalf of all investors in the fund.
  • The tax benefits of an IRA (like tax-deferred growth or tax-free withdrawals) explore no matter what investments you hold inside it.

What an IRA actually is

An IRA is a retirement savings account with special tax treatment. The government created IRAs to encourage people to save for retirement by offering tax breaks. When you open an IRA, you choose which financial institution holds it — a bank, a brokerage firm, or an investment company. That institution keeps track of your money and enforces the rules about how much you can put in each year and when you can take it out.

There are two main types: a Traditional IRA and a Roth IRA. With a Traditional IRA, you may be able to deduct your contributions from your taxes in the year you make them, but you pay taxes on the money when you withdraw it in retirement. With a Roth IRA, you contribute money that has already been taxed, but the money grows tax-free and you do not pay taxes on withdrawals in retirement. Both types have rules about when you can withdraw money without penalty — generally not before age 59½.

What a mutual fund actually is

A mutual fund is an investment product managed by a professional. The fund manager takes money from many investors, pools it together, and uses it to buy a collection of stocks, bonds, or other securities. When you buy shares of a mutual fund, you own a small piece of that entire collection. If the value of the securities in the fund goes up, your shares go up in value. If they go down, your shares go down.

Mutual funds come in many varieties. Some focus on large company stocks, others on small company stocks, others on bonds, others on a mix of stocks and bonds. Some are actively managed, meaning the manager constantly buys and sells securities to try to beat the market. Others are index funds, meaning they straightforward hold the same stocks or bonds as a particular market index and do not try to beat it. You pay a fee to the fund company for managing the fund, which is taken out of your returns.

How they work together

When you open an IRA, you then decide what to invest that money in. Many people choose to buy mutual funds inside their IRA. For example, you might open a Roth IRA at a brokerage firm, then use the money in that IRA to buy shares of a stock index mutual fund. The mutual fund is the investment; the IRA is the account structure that gives you the tax benefits.

But you do not have to buy mutual funds in an IRA. You could instead buy individual stocks, individual bonds, money market funds, or straightforward hold cash. The IRA is just the container. The tax advantages of the IRA explore no matter what you hold inside it. If you hold a mutual fund in a Traditional IRA, the fund's gains are not taxed each year the way they would be in a regular account — they grow tax-deferred until you withdraw the money.

Why people mix up the two

The confusion is understandable because both involve money and investing, and many people do hold mutual funds inside IRAs. Financial companies also sometimes advertise "IRA mutual funds" — meaning mutual funds that are designed to be held in an IRA, often with a target retirement date built in. But the name is just marketing. The mutual fund is still the investment, and the IRA is still the account.

Another source of confusion: some people use "IRA" loosely to mean any retirement savings, and some use "mutual fund" loosely to mean any investment. But in the financial world, these terms have specific meanings. An IRA is a specific type of account with specific rules. A mutual fund is a specific type of investment product with a specific structure.

What you can hold inside an IRA instead of mutual funds

If you open an IRA at a brokerage, you have choices about what to invest in. Many people choose mutual funds because they offer when ready diversification — one mutual fund holds many different securities. But you could also buy individual stocks, individual bonds, exchange-traded funds (ETFs), or straightforward hold cash in the account and not invest it at all.

Some IRAs are more limited. If you open an IRA at a bank, you might only be able to hold savings accounts, CDs, or money market accounts — not mutual funds or stocks. If you open an IRA at a mutual fund company like Vanguard or Fidelity, you can hold their mutual funds and also individual stocks and bonds. The institution you choose determines what options are available to you.

Frequently Asked Questions

Can I have an IRA without holding any mutual funds?

Yes. You can open an IRA and hold only cash, or only individual stocks, or only bonds, or any combination. Many people hold mutual funds because they are convenient and diversified, but there is no requirement to do so. Some people hold individual stocks in an IRA and never buy a mutual fund.

If I buy a mutual fund in a regular brokerage account instead of an IRA, do I get the same tax benefits?

No. The tax benefits come from the IRA account structure, not from the mutual fund itself. A mutual fund held in a regular taxable account is taxed on its gains and dividends each year. The same mutual fund held in an IRA grows tax-deferred (Traditional) or tax-free (Roth). The investment is identical; the tax treatment is different because of the account type.

What if I want to move my mutual fund from a regular account into an IRA?

You can transfer money from a regular brokerage account into an IRA, but you should know the contribution limits. For 2024, you can contribute up to $7,000 per year to an IRA (or $8,000 if you are age 50 or older). If you transfer more than that in a single year, the excess may be subject to taxes and penalties. Talk to your brokerage about the process before you move money.

Are all mutual funds available inside all IRAs?

No. The mutual funds available depend on where you open your IRA. If you open an IRA at Vanguard, you can hold Vanguard mutual funds and also buy funds from other companies. If you open an IRA at Fidelity, you have access to Fidelity funds and others. Some smaller banks may only offer their own mutual funds or none at all. Ask the institution what options are available before you open the account.
