What retirement accounts do and how to choose one

A retirement savings account is a bank or investment account designed to hold money you set aside for after you stop working. The main advantage is tax treatment — depending on the account type, you either pay no tax on the money you contribute, no tax on the growth, or no tax when you withdraw it in retirement. The tradeoff is that most retirement accounts penalize you if you take the money out before age 59½.

The account type you choose depends on whether you have an employer and how much you earn. If your employer offers a 401(k) or 403(b) plan, that is usually the fastest route because your employer may match part of what you contribute — that is assistance programs. If you are self-employed or your employer does not offer a plan, you can open an IRA (Individual Retirement Account) on your own at a bank or brokerage. If you earn too much to contribute to a traditional IRA, a backdoor Roth or SEP-IRA may be an option, but those involve extra steps.

The difference between a traditional account and a Roth account matters for taxes. With a traditional account, you deduct contributions from your income now and pay tax when you withdraw later. With a Roth, you pay tax now and withdraw tax-free later. Roth accounts also let you withdraw contributions (not earnings) before retirement without penalty, which makes them more flexible if you need access to the money.

Key Takeaways

  • If your employer offers a 401(k) or 403(b), start there — especially if they match contributions, because that match is immediate money added to your account.
  • If you do not have an employer plan, you can open an IRA at any bank or brokerage in under an hour, and contribution limits are lower but still substantial.
  • Traditional accounts reduce your taxes now; Roth accounts reduce your taxes in retirement — which one makes sense depends on whether you expect to earn more now or later.
  • Most retirement accounts penalize withdrawals before age 59½, so do not open one with money you might need within five years.
  • You can have both an employer plan and an IRA at the same time, but contribution limits apply across both accounts combined.

How to enroll in an employer 401(k) or 403(b)

If your employer offers a retirement plan, the enrollment process usually happens during onboarding or during an annual open enrollment period (often in the fall). Your HR or benefits department will give you a plan document that lists the investment options available — typically mutual funds or target-date funds that automatically shift from stocks to bonds as you approach retirement.

You choose how much of each paycheck to contribute, usually as a percentage of your salary. The money comes out before taxes, which lowers your taxable income for the year. Your employer will also tell you whether they match contributions — for example, matching 50 cents for every dollar you contribute up to 6% of your salary. If they do match, contribute at least enough to get the full match; anything less is leaving money on the table.

Once you enroll, the contributions start automatically on your next paycheck. You can change your contribution amount or investment choices during open enrollment or, in some plans, at any time through your employer's benefits portal. If you leave the job, you can roll the money into an IRA or into your new employer's plan if they allow it.

Opening an IRA at a bank or brokerage

To open an IRA on your own, go to the website of a bank, credit union, or brokerage — common choices include Fidelity, Vanguard, Charles Schwab, and most major banks. Look for "Open an IRA" or "Retirement Accounts" and choose whether you want a traditional or Roth IRA. You will need your Social Security number, date of birth, and current address.

The application takes 10 to 20 minutes and is entirely online. You will be asked to verify your identity, usually by answering security questions or uploading a photo of your driver's license. Once approved, you can fund the account by linking a bank account and transferring money, or by mailing a check. Some institutions also allow you to fund by rolling over money from an old employer plan.

After funding, you choose how the money is invested — the institution will offer mutual funds, index funds, stocks, or bonds. If you are unsure, a target-date fund is a simple choice; you pick the fund labeled with the year you expect to retire, and the fund automatically rebalances itself over time. You can change your investments at any time without penalty.

Understanding contribution limits and tax deductions

The IRS sets annual limits on how much you can contribute to retirement accounts. For 2024, you can contribute up to $7,000 to an IRA (or $8,000 if you are 50 or older). For a 401(k) or 403(b), the limit is $23,500 (or $31,000 if you are 50 or older). These limits apply across all accounts of the same type — if you have two IRAs, your combined contributions cannot exceed $7,000.

If you have an employer plan and also an IRA, you can contribute to both, but your ability to deduct traditional IRA contributions may be limited if you earn above a certain threshold and are covered by an employer plan. Roth IRA contributions have income limits too — if you earn too much, you cannot contribute directly to a Roth, though you can use a backdoor Roth strategy (which involves contributing to a traditional IRA and then converting it). Your tax preparer or the brokerage can tell you whether you hit these limits.

The contribution limits increase slightly each year to keep pace with inflation, so check the current year's limit before you contribute. You can contribute for the previous year until the tax filing deadline (usually April 15), so if you missed 2023, you have until mid-April 2024 to make up that contribution.

Funding your account and setting up automatic contributions

Once your account is open, you can fund it in a lump sum or set up automatic transfers from your bank account. Automatic transfers are the easiest way to build the habit — most institutions let you schedule a monthly or biweekly transfer of any amount you choose. This way you do not have to remember to contribute, and the money goes in consistently.

If you are rolling over money from an old employer plan, ask your previous employer's benefits department for a rollover form. You can do a direct rollover, where the money goes straight from the old plan to your new IRA without touching your hands — this avoids taxes and penalties. If the money goes to you first, you have 60 days to deposit it into the new account, or it counts as a withdrawal and you owe taxes and penalties.

If you receive a bonus, tax refund, or inheritance, you can contribute that money to your retirement account up to the annual limit. This is a good way to catch up if you have not been able to contribute much during the year.

What happens if you change jobs or retire

If you leave a job where you have a 401(k) or 403(b), you have several options. You can leave the money in the old plan if the balance is above a certain amount (usually $5,000), roll it into your new employer's plan if they accept rollovers, or roll it into an IRA. A rollover to an IRA gives you more investment choices and usually lower fees, so it is often the best choice.

To do a rollover, contact your old employer's benefits department and ask for a rollover form. They will send the money directly to your new IRA — do not ask them to send it to you, because that triggers a 60-day deadline and withholding taxes. The rollover itself is not a taxable event; you only pay taxes when you withdraw the money in retirement.

If you retire before age 59½ and need to withdraw from your retirement account, you will owe a 10% early withdrawal penalty plus income tax on the money, unless you may have access to for an exception (such as disability, medical expenses, or a first-time home purchase up to $10,000). Some plans offer a Rule of 55 exception that lets you withdraw penalty-free if you left the job in the year you turned 55 or later, but this does not apply to IRAs.

Common mistakes to avoid when opening a retirement account

The biggest mistake is not contributing enough to get your employer's full match. If your employer matches 50 cents per dollar up to 6% of salary and you only contribute 3%, you are leaving 3% of your salary on the table every year. That adds up to thousands of dollars over a career.

Another mistake is choosing investments that are too conservative or too aggressive for your timeline. If you are 30 years from retirement, keeping all your money in a money market fund means you miss decades of growth. If you are five years from retirement, keeping all your money in individual stocks exposes you to a market crash right before you need the money. A target-date fund solves this by automatically adjusting as you age.

Do not withdraw money early unless you truly cannot avoid it. The 10% penalty plus taxes can eat 30% to 40% of the withdrawal, and you lose years of growth on that money. If you need emergency funds, keep them in a regular savings account, not a retirement account.

Frequently Asked Questions

Can I open a retirement account if I am self-employed or a freelancer?

Yes. You can open a SEP-IRA or Solo 401(k), both designed for self-employed people. A SEP-IRA is simpler to set up and has higher contribution limits (up to 25% of net self-employment income). A Solo 401(k) is more complex but lets you borrow against your balance. You can open either at any brokerage or bank.

What is the difference between a traditional and Roth IRA?

With a traditional IRA, contributions may be tax-deductible now and you pay tax on withdrawals later. With a Roth IRA, you pay tax on contributions now and withdrawals are tax-free later. Roth accounts also let you withdraw contributions (not earnings) before retirement without penalty. Choose Roth if you expect to earn more in retirement; choose traditional if you expect to earn less.

Can I have both a 401(k) and an IRA at the same time?

Yes, but contribution limits apply across both. For 2024, you can contribute up to $7,000 to an IRA and up to $23,500 to a 401(k) in the same year. However, if you have a 401(k) through your employer, your ability to deduct traditional IRA contributions may be limited based on your income.

What if I do not have enough money to contribute right now?

Start with whatever you can afford, even $50 or $100 per month. The key is to start early so your money has time to grow. You can increase contributions later when you get a raise or bonus. Many employers let you change your contribution amount at any time.

Do I have to choose investments when I open a retirement account?

Yes, but you do not have to pick individual stocks or bonds. A target-date fund is a simple choice — pick the fund labeled with your expected retirement year, and it handles the rest automatically. You can change your investments at any time without penalty or tax consequences.
