Roth IRA for Beginners: How to Open One and What to Invest In

Short answer: a Roth IRA for beginners is a retirement account you fund with money you have already paid tax on, so qualified withdrawals in retirement are tax-free. To open one, you need earned income, an eligible income level, and an account at a brokerage or robo-adviser. Open it online in about 15 minutes, fund it by bank transfer, and then invest the cash in a low-cost diversified fund, because the account only grows once you choose investments.

Key takeaways

• Contributions are made with after-tax money. Growth and qualified withdrawals can be tax-free.
• You must have earned income to contribute, and there are income limits and a yearly contribution limit. Check the current numbers with the IRS.
• Opening the account is not investing. You still need to buy a fund inside it.
• You can generally withdraw what you contributed at any time, but earnings have rules.

Who can contribute to a Roth IRA?

• You need earned income, such as wages or self-employment income, at least as large as your contribution.
• Your income must be below a limit. The ability to contribute phases out at higher incomes, and the thresholds change each year and depend on your filing status.
• There is a yearly contribution limit, which is higher for people aged 50 and over, and applies across all your IRAs combined.

Check the current numbers on the IRS website before you contribute. You can contribute for a tax year up to the tax filing deadline in the following spring.

How do you open a Roth IRA?

1. Choose a provider. A brokerage lets you pick your own investments. A robo-adviser builds and manages a portfolio for a fee. Compare fees, available funds and ease of use. Large, low-cost brokerages are a common choice.
2. Gather your details. Your Social Security number, a photo ID, your employer's details, a beneficiary, and your bank account and routing numbers.
3. Apply online. It usually takes 10 to 15 minutes, with approval often within a day.
4. Fund it. A bank transfer is most common and takes a few business days. You can also set up automatic monthly contributions.
5. Invest the money. Cash in a Roth IRA does not grow. Buy your chosen funds.

What should you invest in inside a Roth IRA?

• A target-date fund. One fund that shifts from stocks toward bonds as your retirement year nears.
• A broad index fund or ETF. A total stock market fund is a common core holding for long-term money. See index funds, ETFs and mutual funds.
• A mix of stock and bond funds if you prefer to set your own balance. See asset allocation.

Because a Roth IRA is for long-term money, many people lean toward stocks, which are most useful when held for decades. Keep costs low: check each fund's expense ratio.

What could a Roth IRA grow to?

These assume a constant 7% annual return and contributions within the yearly limit. In a Roth, the growth is not taxed if you follow the rules, which is the main appeal. Returns vary every year and are not guaranteed.

What are the Roth IRA withdrawal rules?

• Contributions: you can generally withdraw the money you put in at any time without tax or penalty.
• Earnings: qualified withdrawals are tax-free and penalty-free if the account has been open for at least five years and you are 59 and a half or older, or meet another exception such as disability. Other withdrawals of earnings may face tax and a 10% penalty.
• Use it for retirement. Withdrawing early gives up decades of tax-free growth, so treat it as a last resort.

Roth IRA or traditional IRA?

A Roth uses after-tax money now for tax-free withdrawals later. A traditional IRA may give a deduction now but taxes withdrawals later. Roth often suits people who expect a higher tax rate in the future. Compare the two in Roth vs traditional IRA, and see where an IRA fits in the account order report. Before opening one, make sure you have captured any employer match, as explained in what is a 401(k).
