A Roth IRA and a brokerage account are different legal structures that hold investments differently

A Roth IRA is a retirement account with tax rules and contribution limits set by the IRS. A brokerage account is an investment account with no contribution limits and no special tax treatment. The difference matters because it changes how much you can put in each year, when you can take money out without penalty, and how you pay taxes on gains.

You can own both at the same time. Many people do. But they are separate accounts with separate rules, and money in one does not count toward limits in the other.

Key Takeaways

  • A Roth IRA has an annual contribution limit (currently $7,000 for most people under 50), while a brokerage account has no limit on how much you can deposit.
  • Roth IRA withdrawals of earnings before age 59½ usually trigger a 10% penalty plus income tax, while brokerage account withdrawals have no age restriction or penalty.
  • Money grows tax-free in a Roth IRA, but you pay capital gains tax on profits in a brokerage account when you sell.
  • Both types of accounts can hold the same investments — stocks, bonds, mutual funds — but the tax treatment and rules around access are completely different.

How contribution limits work in each account

A Roth IRA has a yearly cap on how much you can deposit. For 2024, that limit is $7,000 if you are under 50, and $8,000 if you are 50 or older. This limit applies to all your IRAs combined — if you have two Roth IRAs at different banks, your total deposits across both cannot exceed $7,000 in a single year.

A brokerage account has no contribution limit. You can deposit $100 or $100,000 in a single month. There is no annual cap, no age restriction, and no income limit. You can open one and fund it as much as you want whenever you want.

This is why people use brokerage accounts when they have already maxed out their Roth IRA for the year but want to invest more money.

Tax treatment: growth and withdrawals

In a Roth IRA, money grows tax-free. When you sell an investment 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 pay no tax on the earnings either. This is the main advantage of a Roth IRA.

In a brokerage account, you pay tax on investment gains when you sell. If you buy a stock for $1,000 and sell it for $1,500, you owe tax on the $500 gain in the year you sell it. You also pay tax on dividends and interest as you earn them, even if you do not withdraw the money. The tax rate depends on how long you held the investment — short-term gains (held less than one year) are taxed as ordinary income, while long-term gains (held over one year) usually get a lower rate.

This tax difference is why a Roth IRA is better for long-term growth if you can use it, and why a brokerage account makes sense for money you might need before retirement.

When you can access your money

In a Roth IRA, you can withdraw your own contributions (the money you put in) at any time without penalty or tax. But if you withdraw earnings (the profits your investments made) before age 59½, you owe a 10% penalty plus income tax on those earnings. There are a few exceptions — first-time home purchase (up to $10,000 lifetime), disability, and a few others — but they are narrow.

In a brokerage account, you can withdraw any amount at any time with no penalty and no age restriction. You may owe tax on gains when you sell, but there is no penalty for taking the money out early.

This is why a brokerage account is the right choice for money you might need in the next five to ten years. A Roth IRA is for money you plan to leave alone until retirement.

Income limits for Roth IRA contributions

A Roth IRA has income limits. If you earn above a certain amount, you cannot contribute the full $7,000 (or $8,000 if 50+). The limit phases out completely at higher incomes. For 2024, the phase-out range for single filers starts at $146,000 and ends at $161,000. For married filing jointly, it starts at $230,000 and ends at $240,000. These numbers change each year.

A brokerage account has no income limit. Anyone can open one and deposit as much as they want, regardless of how much they earn.

If your income is too high for a Roth IRA contribution, a brokerage account is your only option for investing additional money beyond what you can put in a 401(k) or other workplace plan.

What investments you can hold in each

Both a Roth IRA and a brokerage account can hold the same types of investments: individual stocks, bonds, mutual funds, exchange-traded funds (ETFs), and some other securities. The investments themselves are the same. The difference is the tax wrapper around them and the rules about when you can access the money.

Some IRAs (including Roths) have restrictions on certain investments like real estate or private equity, depending on your provider. But for standard stocks and funds, both account types offer the same menu of choices.

Using both accounts together

Many people use a Roth IRA for long-term retirement savings and a brokerage account for shorter-term goals or for investing money beyond the annual Roth limit. This is a common strategy and there is no rule against it.

The key is to understand which money goes where. Money in your Roth IRA counts toward your annual contribution limit and is locked away until retirement (with narrow exceptions). Money in a brokerage account is separate, has no limit, and you can access it whenever you need it — though you will owe tax on gains when you sell.

Frequently Asked Questions

Can I move money from a brokerage account into a Roth IRA?

You can transfer the cash, but not the investments themselves. You would need to sell the investments in your brokerage account, move the cash to your Roth IRA, and buy new investments there. The sale may trigger capital gains tax. The cash you move counts toward your annual Roth IRA contribution limit for that year.

Do I have to report both accounts on my taxes?

You report the brokerage account if you sold investments or earned dividends and interest. You do not report the Roth IRA itself on your tax return unless you took a withdrawal. When you do withdraw from a Roth IRA, your provider sends you a form showing what came out.

What happens if I contribute too much to my Roth IRA in one year?

The excess contribution is subject to a 6% penalty tax each year it stays in the account. You can fix this by withdrawing the excess (plus any earnings on it) before your tax return deadline. It is better to catch it early than to let it sit.

Can I have a Roth IRA and a regular brokerage account at the same bank?

Yes. Most banks and brokerages let you open multiple account types. They are separate accounts with separate login credentials and separate contribution tracking, but you can manage them in one place.
