Investment accounts come in three main types: brokerage accounts you open yourself, retirement accounts with tax advantages, and robo-advisors that manage money for you

The place you invest depends on what you are saving for and how much control you want. A brokerage account is the most straightforward: you open one at a bank, credit union, or investment firm, deposit money, and buy stocks, bonds, mutual funds, or exchange-traded funds (ETFs) yourself. A retirement account — like a 401(k), IRA, or Roth IRA — is designed to hold money until you reach a certain age and offers tax breaks in exchange. A robo-advisor is a service that takes your money and invests it automatically based on your goals and risk tolerance, charging a small fee to manage it.

Each type has different rules about when you can withdraw money, how much you can put in per year, and what taxes you pay. The right choice depends on whether you are saving for retirement, a house down payment, education, or something else entirely.

Key Takeaways

  • Brokerage accounts have no contribution limits and let you withdraw money anytime, but you pay taxes on gains and dividends each year.
  • Retirement accounts like 401(k)s and IRAs offer tax breaks but penalize you for withdrawing before age 59½, with some exceptions for hardship.
  • Robo-advisors charge a yearly fee (usually 0.25% to 0.50% of your balance) to invest your money automatically based on your risk level.
  • Banks, credit unions, investment firms like Fidelity and Vanguard, and online brokers like E-Trade all offer accounts; the main differences are fees and customer service.
  • Your employer may offer a 401(k) with matching contributions, which is usually the best starting point because the match is assistance programs.

Brokerage accounts: how they work and what they cost

A brokerage account is a regular investment account with no special tax treatment. You open one, deposit money, and buy and sell investments whenever you want. You can withdraw the money anytime without penalty. The trade-off is that you pay taxes on any profits (called capital gains) and on dividends each year, even if you do not withdraw the money.

Most brokers now charge zero commission to buy stocks and ETFs, meaning you do not pay per trade. However, some charge annual account fees if your balance is below a certain amount — often $2,500 to $10,000 — so check before opening. Mutual funds sometimes carry an internal fee called an expense ratio, which is a percentage of your balance taken yearly to cover management costs. ETFs usually have lower expense ratios than mutual funds.

Brokerage accounts are useful for saving toward a house, car, or other goal within the next few years, because you can access the money without penalty. They are also useful if you have already maxed out your retirement account contributions for the year.

Retirement accounts: 401(k)s, IRAs, and Roth IRAs

A 401(k) is an employer-sponsored retirement account. Your employer sets it up, and you contribute money directly from your paycheck before taxes are taken out. Many employers match a portion of what you contribute — for example, they might add 50 cents for every dollar you put in, up to 6% of your salary. That match is immediate assistance programs and is the main reason to open a 401(k) if your employer offers one.

An IRA (Individual Retirement Account) is a retirement account you open yourself at a bank, credit union, or brokerage. A traditional IRA lets you deduct your contributions from your taxes in the year you make them, but you pay taxes when you withdraw the money in retirement. A Roth IRA works the opposite way: you contribute money after taxes, but withdrawals in retirement are tax-free. Roth IRAs also let you withdraw your contributions (not earnings) anytime without penalty, which makes them more flexible than traditional IRAs.

All retirement accounts penalize you for withdrawing before age 59½. The penalty is usually 10% of the amount withdrawn, plus you owe income tax on it. Some exceptions exist — you can withdraw from a Roth IRA for a first home purchase, education, or medical hardship — but the rules are strict. Contribution limits change yearly; for 2024, you can put $7,000 into an IRA and $23,500 into a 401(k) if you are under 50.

Robo-advisors: automated investing with lower fees

A robo-advisor is a company that invests your money automatically. You answer questions about your age, income, and goals, and the service builds a portfolio of stocks and bonds matched to your risk level. It then rebalances your portfolio periodically — selling investments that have grown too large and buying ones that have shrunk — to keep your risk level steady.

Robo-advisors charge a yearly fee, usually between 0.25% and 0.50% of your total balance. Some also charge a monthly minimum (often $0 to $10) if your balance is small. The advantage is that you do not have to pick individual investments or rebalance yourself. The disadvantage is that you have less control over what you own and cannot easily customize your portfolio for tax reasons.

Popular robo-advisors include Betterment, Wealthfront, and Vanguard Personal Advisor Services. Many also offer retirement accounts (IRAs and 401(k)s), so you can get both the automated investing and the tax advantages in one place.

Where to open an account: banks, brokers, and online platforms

You can open an investment account at several types of institutions. Banks and credit unions offer brokerage accounts and IRAs, though they often have higher fees and fewer investment options than dedicated brokers. Investment firms like Fidelity, Vanguard, and Charles Schwab offer a full range of accounts and usually have low fees and good customer service. Online brokers like E-Trade, TD Ameritrade, and Interactive Brokers are cheaper but offer less hand-holding.

If your employer offers a 401(k), you enroll through your employer's plan administrator, not by opening an account yourself. The administrator is usually a company like Fidelity, Vanguard, or Merrill Lynch that manages the plan on behalf of your employer.

The main differences between institutions are fees, the range of investments available, and customer service quality. Most brokers now offer zero-commission trading, so the deciding factor is usually the expense ratios on their mutual funds and ETFs, and whether they charge account maintenance fees. Comparing two or three before opening an account takes 20 minutes and can save you hundreds of dollars over time.

How much you can invest each year

Brokerage accounts have no contribution limits — you can put in as much as you want. Retirement accounts have annual limits set by the IRS. For 2024, you can contribute $7,000 to an IRA (traditional or Roth combined), $23,500 to a 401(k), and $4,150 to a Health Savings Account (HSA) if you have a high-deductible health plan. If you are 50 or older, you can contribute an extra $1,000 to an IRA and $7,500 to a 401(k) as "catch-up" contributions.

These limits reset January 1 each year. If you do not use your full contribution room in one year, you cannot carry it forward to the next year — the unused amount is lost. However, if you contribute more than the limit by mistake, you can withdraw the excess and avoid penalties if you do so before your tax filing deadline.

Tax considerations when choosing where to invest

The tax treatment of your investments depends on the account type. In a traditional 401(k) or IRA, you do not pay taxes on gains or dividends while the money is invested; you pay taxes only when you withdraw. In a Roth IRA or Roth 401(k), you pay taxes upfront but withdrawals are tax-free. In a regular brokerage account, you pay taxes on gains and dividends each year.

This matters because it affects how much money you keep. If you are in a high tax bracket, a Roth account may be better because you lock in today's tax rate. If you expect to be in a lower tax bracket in retirement, a traditional account may be better. An HSA is the most tax-efficient account available — contributions are tax-deductible, growth is tax-free, and withdrawals for medical expenses are tax-free — but you can only use it if your health insurance plan qualifies.

Frequently Asked Questions

What is the difference between a brokerage account and a retirement account?

A brokerage account has no contribution limits and lets you withdraw money anytime, but you pay taxes on gains each year. A retirement account has annual contribution limits and penalizes withdrawals before age 59½, but offers tax breaks. Choose a brokerage account for short-term savings and a retirement account for long-term retirement savings.

Should I open a Roth IRA or a traditional IRA?

A Roth IRA is better if you expect to be in a higher tax bracket in retirement or want flexibility to withdraw contributions early. A traditional IRA is better if you want to reduce your taxes this year. You can open both and split your contributions between them, as long as your combined contributions do not exceed the annual limit.

Do I have to use my employer's 401(k), or can I open my own retirement account?

You can do both. If your employer offers a 401(k) with matching contributions, open that first and contribute enough to get the full match — it is assistance programs. Then open an IRA for additional retirement savings. You can contribute to both in the same year as long as you stay within the annual limits for each.

What happens if I withdraw money from a retirement account early?

You usually pay a 10% penalty plus income tax on the amount withdrawn. Some exceptions exist: Roth IRA contributions can be withdrawn anytime penalty-free, and both traditional and Roth IRAs allow withdrawals for first-time home purchases, education, or medical hardship. Check the specific rules for your account type before withdrawing.

How do I know which robo-advisor to choose?

Compare the yearly fee (usually 0.25% to 0.50%), any account minimums, the investment options available, and whether they offer retirement accounts. Most robo-advisors let you see a sample portfolio before opening an account. If you have less than $10,000 to invest, a robo-advisor with no minimum is a good choice.
