The three account types are taxable, tax-deferred, and tax-free

A brokerage account is a container that holds your investments—stocks, bonds, mutual funds, exchange-traded funds (ETFs). The type of account you choose determines how the IRS taxes your money when you buy, sell, or collect dividends. The three main types are taxable brokerage accounts, tax-deferred accounts (like traditional IRAs and 401(k)s), and tax-free accounts (like Roth IRAs and Roth 401(k)s). Each one has different rules about when you can withdraw money, how much you can contribute per year, and what taxes you owe.

The account type you pick depends on your age, income, how soon you need the money, and whether you have access to an employer retirement plan. Most people use more than one type over their lifetime.

Key Takeaways

  • Taxable brokerage accounts have no contribution limits and no withdrawal restrictions, but you pay taxes on gains and dividends every year.
  • Tax-deferred accounts like traditional IRAs and 401(k)s let you deduct contributions from your income now, but you pay taxes on all withdrawals later.
  • Tax-free accounts like Roth IRAs and Roth 401(k)s take after-tax money now, but withdrawals in retirement are tax-free.
  • Contribution limits and withdrawal penalties vary by account type and change yearly, so check the current rules before you open an account.
  • You can hold all three types at the same time and move money between them under specific rules.

Taxable brokerage accounts: no limits, but you pay taxes every year

A taxable brokerage account is the most flexible. You can open one at any age, contribute as much as you want, and withdraw money whenever you need it without penalty. There is no annual contribution limit. You can buy and sell as often as you like.

The trade-off is taxes. Every time you sell an investment for a profit, you owe capital gains tax on the difference between what you paid and what you sold it for. If you hold the investment for more than one year before selling, that gain is taxed as a long-term capital gain, which is usually lower than your regular income tax rate. If you sell within one year, it is taxed as a short-term capital gain at your regular income tax rate. You also owe taxes on dividends and interest the account earns, even if you do not withdraw the money. You report these taxes on your annual tax return.

Taxable accounts are useful for money you do not plan to retire on—a down payment fund, a car purchase, or money beyond what you can fit into retirement accounts. They are also the only option if your income is too high to use a Roth IRA or if you have already maxed out your retirement account contributions for the year.

Tax-deferred accounts: lower taxes now, but you pay later

A traditional IRA or traditional 401(k) lets you contribute money before taxes are taken out. If you earn $60,000 and contribute $7,000 to a traditional IRA, your taxable income drops to $53,000 for that year. You do not owe taxes on the $7,000 or on any gains it earns while it sits in the account.

The catch is that you pay taxes on everything when you withdraw it in retirement. If your $7,000 grows to $50,000 by age 65, you owe income tax on the full $50,000 when you take it out. This works well if you expect to be in a lower tax bracket in retirement than you are now, or if you simply want to delay taxes to a later year.

Tax-deferred accounts have strict rules. You cannot withdraw money before age 59½ without paying a 10% penalty on top of income tax, with some exceptions (first-time home purchase, disability, medical hardship). You must start taking withdrawals at age 73 (as of 2023; this age changes yearly). If you have a 401(k) through your employer, your employer may match a portion of your contribution—assistance programs that goes into the account.

For 2024, you can contribute up to $7,000 to a traditional IRA if you are under 50, or $8,000 if you are 50 or older. If you have a 401(k), the limit is much higher—$23,500 for those under 50, or $31,000 if you are 50 or older. These limits change yearly.

Tax-free accounts: pay taxes now, withdraw tax-free later

A Roth IRA or Roth 401(k) works backward. You contribute money that has already been taxed. You do not get a tax deduction that year. But the money grows tax-free, and when you withdraw it in retirement, you owe no taxes on any of it—not the original contribution, not the gains.

If you contribute $7,000 to a Roth IRA at age 30 and it grows to $50,000 by age 65, you can withdraw the full $50,000 tax-free. This is powerful if you expect to be in a higher tax bracket in retirement, or if you simply want to lock in today's tax rate and avoid future tax increases.

Roth accounts have income limits. For 2024, you cannot contribute to a Roth IRA if your income is above a certain threshold (this varies by filing status and changes yearly). There is no income limit for a Roth 401(k) if your employer offers one. You can withdraw your original contributions to a Roth IRA anytime without penalty, but earnings must stay in the account until age 59½. You are not required to take withdrawals at any age, which makes Roth accounts useful for leaving money to heirs.

The 2024 contribution limit for a Roth IRA is $7,000 if you are under 50, or $8,000 if you are 50 or older. Roth 401(k) limits match traditional 401(k) limits.

How to choose between the three types

Start with your employer's 401(k) if one is offered and your employer matches contributions. That match is immediate assistance programs. Contribute enough to get the full match, then decide where to put additional savings.

If you expect to be in a lower tax bracket in retirement, a traditional IRA or 401(k) makes sense now. If you expect to be in a higher bracket, or if you want to avoid taxes entirely in retirement, a Roth account is better. If you have already maxed out your retirement accounts and still have money to invest, open a taxable brokerage account.

Many people use all three types. A common strategy is to max out a Roth IRA first (if you are under the income limit), then contribute to an employer 401(k) up to the match, then use a taxable account for anything left over.

Moving money between accounts: rollovers and conversions

You can move money from one account type to another under specific rules. A rollover moves money from one retirement account to another—for example, from an old employer's 401(k) to an IRA—without triggering taxes or penalties, as long as you complete the transfer within 60 days or use a direct transfer.

A Roth conversion moves money from a traditional IRA or 401(k) to a Roth account. You owe income tax on the amount you convert, but the money then grows tax-free. This is useful if you expect tax rates to rise, or if you want to reduce the size of your traditional retirement accounts before you are forced to take withdrawals at age 73.

You cannot move money from a taxable account into a retirement account without starting fresh—you cannot "convert" a taxable brokerage account into an IRA. You can only contribute new money to retirement accounts, up to the annual limit.

Frequently Asked Questions

Can I have more than one of each account type?

Yes. You can have multiple IRAs, multiple 401(k)s (if you change jobs), and multiple taxable brokerage accounts. However, your total contributions across all traditional IRAs in a year cannot exceed the annual limit, and the same rule applies to Roth IRAs. 401(k) limits apply per employer, so you can contribute the maximum to each employer's plan if you work multiple jobs.

What happens if I withdraw money early from a tax-deferred account?

You owe income tax on the withdrawal plus a 10% penalty, with exceptions for disability, medical hardship, first-time home purchase (up to $10,000), and a few other situations. The penalty is steep, so early withdrawal should be a last resort. Roth IRA contributions (not earnings) can be withdrawn anytime without penalty.

Do I have to choose one account type or can I use all three?

You can use all three. Many people contribute to an employer 401(k), open a Roth IRA, and use a taxable account for additional savings. Each serves a different purpose in your overall financial plan.

What if my income is too high for a Roth IRA?

You can still contribute to a traditional IRA (though the deduction may be limited if you have a 401(k)), or you can ask your employer if they offer a Roth 401(k), which has no income limit. Some people use a "backdoor Roth" strategy, which involves contributing to a traditional IRA and then converting it to a Roth, though this has tax complications if you already have other traditional IRAs.

How do I know which account to fund first each year?

Prioritize in this order: contribute to your employer 401(k) up to the match, then max out a Roth IRA if you are under the income limit, then go back to your 401(k) to reach the full contribution limit, then use a taxable account. This order assumes you want to minimize taxes, but your situation may differ based on your income and retirement timeline.
