The main places to invest depend on your tax situation and how long you can leave the money alone

You can invest through a brokerage account you open yourself, through retirement accounts tied to your job or self-employment, through individual retirement accounts (IRAs) you set up on your own, or through your employer's benefits plan. Each has different tax treatment, contribution limits, and rules about when you can withdraw money. The right choice depends on whether you have earned income, whether your employer offers a plan, and whether you want tax breaks now or in retirement.

Most people start with one of three routes: a 401(k) or 403(b) if their employer offers it, an IRA if they don't have an employer plan or want to save more, or a regular taxable brokerage account if they want no restrictions on when they withdraw. Many people use more than one at the same time.

Key Takeaways

  • A 401(k) or 403(b) through your employer often includes matching contributions, which is assistance programs you should capture before saving elsewhere.
  • IRAs (Traditional or Roth) let you save up to $7,000 per year with tax advantages, and you can open one at any brokerage even if your employer has no plan.
  • A taxable brokerage account has no contribution limits and no withdrawal restrictions, but you pay taxes on gains and dividends each year.
  • Health Savings Accounts (HSAs) triple as a savings vehicle if you have a high-deductible health plan, with tax-free growth and withdrawals for medical costs.
  • The order usually matters: capture employer match first, then max out tax-advantaged accounts, then use a taxable account for anything beyond that.

Employer-sponsored plans: 401(k), 403(b), and SIMPLE IRAs

If your employer offers a 401(k) (for-profit companies), 403(b) (nonprofits and schools), or SIMPLE IRA (small businesses), you can contribute directly from your paycheck before taxes are taken out. Your contributions reduce your taxable income for that year. The money grows tax-free until you withdraw it in retirement, when you pay income tax on the full amount.

Many employers match a portion of what you contribute—often 50 cents or a dollar for every dollar you put in, up to a certain percentage of your salary. This match is not may provide and varies by employer. If your employer offers a match, contributing enough to capture the full match should be your first savings priority, because it is immediate return on your money.

Contribution limits for 2024 are $23,500 for a 401(k) or 403(b) and $16,000 for a SIMPLE IRA, though these change yearly. You cannot withdraw money before age 59½ without penalty (with narrow exceptions), so these accounts are meant for long-term retirement saving. If you leave your job, you can roll the balance into an IRA or another employer plan to keep it invested.

Individual Retirement Accounts (IRAs): Traditional and Roth

An IRA is an account you open yourself at a brokerage, bank, or robo-advisor. You can open one whether or not your employer has a retirement plan. For 2024, you can contribute up to $7,000 per year if you are under 50, or $8,000 if you are 50 or older. You do not need to contribute the full amount every year.

A Traditional IRA works like a 401(k): contributions may be tax-deductible in the year you make them (depending on your income and whether you have an employer plan), and the money grows tax-free. You pay income tax on withdrawals in retirement. You must start taking withdrawals at age 73 (as of 2023), whether you need the money or not.

A Roth IRA takes the opposite approach. You contribute money that has already been taxed, so you get no deduction now. But the money grows tax-free, and withdrawals in retirement are tax-free too. There is no requirement to withdraw at any age, which makes a Roth useful if you want to leave money to heirs or do not need it in retirement. However, income limits apply: if you earn above a certain threshold, you cannot contribute directly to a Roth. For 2024, the phase-out begins at $146,000 for single filers and $230,000 for married filing jointly, though these limits change yearly.

You can open an IRA at nearly any brokerage—Fidelity, Vanguard, Charles Schwab, and many others offer them with no account minimums. The IRA is just the container; inside it, you choose what to invest in (stocks, bonds, funds, or cash).

Taxable brokerage accounts: No limits, no restrictions

A taxable brokerage account is a regular investment account with no contribution limits and no rules about when you can withdraw. You can open one at any brokerage and invest as much as you want, whenever you want. You can also withdraw anytime without penalty.

The trade-off is taxes. You pay capital gains tax on profits when you sell, and you pay tax on dividends and interest each year, even if you do not withdraw the money. Long-term capital gains (on assets held over a year) are taxed at a lower rate than short-term gains or ordinary income, but you still owe tax annually. This makes taxable accounts less efficient for frequent trading or high-dividend stocks.

Taxable accounts are useful for money you may need before retirement, for saving beyond the limits of tax-advantaged accounts, or for investors who want complete flexibility. They are also the only option if you have no earned income (for example, if you live on investment returns or inheritance).

Health Savings Accounts (HSAs): Triple tax advantage

An HSA is available only if you are enrolled in a high-deductible health plan (HDHP) through your employer or the individual market. For 2024, a high-deductible plan has a deductible of at least $1,600 for individual coverage or $3,200 for family coverage.

An HSA works like a Traditional IRA for medical expenses. You contribute pre-tax money (or get a tax deduction if you contribute after-tax), the money grows tax-free, and withdrawals for may have access to medical costs are tax-free. If you withdraw for non-medical reasons before age 65, you pay income tax plus a 20% penalty. After 65, you can withdraw for any reason and pay only income tax (like a Traditional IRA), but non-medical withdrawals lose the tax-free status.

The real advantage is that you can invest HSA money rather than spend it immediately. Many people use an HSA as a retirement account by paying medical costs out of pocket and letting the HSA balance grow invested. Contribution limits for 2024 are $4,150 for individual coverage and $8,300 for family coverage, and you can carry unused balances forward indefinitely.

Brokerage platforms and where to open accounts

Once you decide what type of account to use, you need a place to open it. Major brokerages include Fidelity, Vanguard, Charles Schwab, E*TRADE, and Interactive Brokers. Smaller or specialized platforms include Betterment, Wealthfront, and M1 Finance. Banks like Chase and Bank of America also offer brokerage services.

Most brokerages charge no account fees and no commissions on stock or fund trades. They differ in account minimums (many have none), investment options, research tools, and customer service. Some offer robo-advisors that automatically build and rebalance a portfolio for you; others let you pick individual investments. If you are unsure where to start, Vanguard and Fidelity are widely used and have low costs and broad investment menus.

The account type (401(k), IRA, taxable) is separate from the brokerage. You can have a Roth IRA at Fidelity and a taxable account at Vanguard, for example. Some employers require you to use a specific platform for your 401(k), but you have freedom to choose where to open an IRA or taxable account.

The order to prioritize: Employer match, then tax-advantaged, then taxable

If you have multiple options, a common strategy is to save in this order. First, contribute enough to your employer plan to capture the full employer match—this is the highest may provide return. Second, max out a Roth or Traditional IRA if you are under the income limits. Third, go back to your employer plan and contribute more if you want to save beyond the IRA limit. Fourth, open a taxable brokerage account for anything beyond that.

This order prioritizes tax-advantaged space, which is limited each year. Once the year ends, you cannot use that year's contribution room again. A taxable account has no limit, so it is the overflow bucket. The exact order may shift based on your income, tax bracket, and whether you expect to be in a higher or lower tax bracket in retirement, but this framework covers most situations.

Frequently Asked Questions

Can I have both a Traditional IRA and a Roth IRA?

Yes, you can have both at the same time. However, your total contributions to both combined cannot exceed the annual limit ($7,000 for 2024 if you are under 50). You can split the money however you want between them, or contribute to one and not the other in a given year.

What if my employer does not offer a retirement plan?

You can open an IRA on your own at any brokerage. If you are self-employed or have side income, you can also open a Solo 401(k) or SEP IRA, which allow higher contributions than a regular IRA. A Solo 401(k) allows up to $69,000 in 2024 (including employer and employee contributions), while a SEP IRA allows up to 25% of your net self-employment income.

Can I invest in individual stocks, or do I have to buy funds?

You can do either. Most brokerages let you buy individual stocks, bonds, and funds in any account type. Many beginners start with funds (mutual funds or exchange-traded funds) because they are diversified and require less research, but you have the choice.

What happens to my 401(k) if I change jobs?

You can leave it with your former employer, roll it into an IRA, or roll it into your new employer's plan if they allow it. Rolling into an IRA gives you more investment choices and lower fees in many cases. You have no time limit to decide, though leaving it behind means you lose access to employer support and may face higher fees.

Do I have to invest the money, or can I keep it in cash?

You can keep money in cash (a money market fund or savings option) inside any account type. However, cash earns very little interest, so most long-term investors put money into stocks or bonds. The account type determines the tax treatment; the investment choice is separate.
