A Roth IRA and a brokerage account are two separate things

A Roth IRA is a retirement savings account with tax rules set by the IRS. A brokerage account is a general investment account with no retirement purpose and no tax rules limiting what you can do with it. You can hold investments in either one, but they work differently and serve different purposes.

The key difference: a Roth IRA has contribution limits, withdrawal rules, and tax benefits tied to retirement. A brokerage account has none of those restrictions. You can put in as much money as you want, take it out whenever you want, and pay taxes on gains each year.

Some people use both. You might max out your Roth IRA first (because of the tax benefits), then put additional money into a brokerage account for more flexibility or to hold investments the IRS doesn't allow in a Roth.

Key Takeaways

  • A Roth IRA is a retirement account with annual contribution limits and withdrawal penalties before age 59½; a brokerage account has no limits or penalties.
  • Money in a Roth IRA grows tax-free and withdrawals in retirement are tax-free; money in a brokerage account is taxed each year on gains and dividends.
  • You choose what investments to hold inside a Roth IRA (stocks, funds, bonds) just as you do in a brokerage account, but the account type itself is different.
  • A brokerage account is useful for saving beyond your Roth IRA limit or for money you may need before retirement.

What you can invest in is the same; the account rules are different

Both a Roth IRA and a brokerage account let you buy stocks, mutual funds, exchange-traded funds (ETFs), and bonds. You open an account with a broker (Fidelity, Vanguard, Charles Schwab, or others), and you choose which investments to hold.

The difference is not what you can buy. The difference is what the IRS allows you to do with the account. A Roth IRA has rules about how much you can put in each year, when you can take money out, and how the money is taxed. A brokerage account has none of those rules.

Contribution limits apply to Roth IRAs, not brokerage accounts

With a Roth IRA, you can contribute only a set amount per year. For 2024, that limit is $7,000 if you are under 50, or $8,000 if you are 50 or older. Once you hit that limit, you cannot put more money into that Roth IRA for the rest of the year, even if you have the money available.

With a brokerage account, there is no limit. You can deposit $100 or $100,000 in a single day. You can add money whenever you want, as much as you want.

This is why many people use both: they max out the Roth IRA first to get the tax benefits, then put extra savings into a brokerage account.

Withdrawal rules are strict for Roth IRAs, flexible for brokerage accounts

In a Roth IRA, you can withdraw the money you contributed (called your "basis") at any time without penalty. But if you withdraw earnings before age 59½, you pay a 10% penalty plus income tax on those earnings, with some exceptions (first-time home purchase, disability, medical expenses).

In a brokerage account, you can withdraw any amount at any time with no penalty. You pay taxes on gains when you sell, but there is no age restriction or withdrawal penalty.

If you think you might need the money before retirement, a brokerage account gives you more flexibility. If you are certain the money will stay invested until retirement, a Roth IRA offers better tax treatment.

Tax treatment differs significantly between the two

Money in a Roth IRA grows tax-free. When you sell an investment inside the Roth at a profit, you owe no tax on that gain. When you withdraw money in retirement (after age 59½ and after holding the account for at least five years), you owe no tax on the earnings.

Money in a brokerage account is taxed each year. If you hold a stock that pays dividends, you owe tax on those dividends in the year you receive them, even if you do not sell the stock. If you sell an investment at a profit, you owe capital gains tax on the profit. This happens every year, which can add up over time.

This tax difference is why a Roth IRA is usually better for long-term retirement savings, if you can afford to leave the money untouched.

You still need a broker to open either account

Whether you open a Roth IRA or a brokerage account, you work with the same brokers: Fidelity, Vanguard, Charles Schwab, E*TRADE, Interactive Brokers, and others. You fill out an account application, provide your Social Security number and address, and link a bank account to fund it.

When you apply, you tell the broker which type of account you want. The broker then enforces the rules (contribution limits for a Roth, no limits for a brokerage). The investments you can buy are the same either way.

Frequently Asked Questions

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

Yes. Most people do. You can max out your Roth IRA contribution each year and then put additional money into a brokerage account. The accounts are separate, and the IRS treats them differently for tax purposes.

If I open a Roth IRA with a broker, am I opening a brokerage account?

No. You are opening a Roth IRA account. The broker holds it and lets you trade inside it, but the account type is determined by what you told the broker when you applied. A Roth IRA is a Roth IRA; a brokerage account is a brokerage account.

Should I use a brokerage account instead of a Roth IRA?

Not instead of. A brokerage account is useful for money beyond your Roth IRA limit or money you may need before retirement. For retirement savings, a Roth IRA usually offers better tax treatment. Many people use both for different purposes.

Do I pay taxes on money I move from a brokerage account to a Roth IRA?

Moving money directly is not allowed. However, you can sell investments in a brokerage account, pay any taxes owed on gains, and then contribute the after-tax money to a Roth IRA (up to the annual limit). This is called a "backdoor Roth" in some situations, though the rules are complex.

Can I hold the same investments in both a Roth IRA and a brokerage account?

Yes. You might hold the same stock or fund in both accounts. The difference is the tax treatment: gains in the Roth are tax-free in retirement, while gains in the brokerage account are taxed each year.
