A Roth IRA is worth opening if you expect to be in a higher tax bracket later, have earned income this year, and can leave the money untouched until age 59½

The core trade-off is simple: you pay taxes on the money going in, but withdrawals in retirement are tax-free. That math works best if your tax rate now is lower than it will be when you retire. If you're young, early in your career, or in a low-income year, a Roth usually makes sense. If you're already in a high tax bracket and want to reduce your taxes this year, a traditional IRA or 401(k) is the better choice.

You can only open a Roth if you have earned income — wages from a job, self-employment income, or taxable alimony. Investment income, Social Security, or disability payments don't count. The income limit also matters: in 2024, you cannot contribute to a Roth if your modified adjusted gross income exceeds $161,000 (single) or $240,000 (married filing jointly). These limits change yearly.

Key Takeaways

  • Open a Roth IRA if you have earned income this year and expect to pay higher taxes in retirement than you do now.
  • You must have earned income to contribute; investment returns, Social Security, and disability payments do not count.
  • Your income cannot exceed the annual limit set by the IRS, which varies by filing status and changes each year.
  • You can withdraw contributions (not earnings) at any time without penalty, but earnings withdrawn before age 59½ usually trigger taxes and a 10% penalty.
  • If you have a 401(k) at work, you can still open and fund a Roth IRA as long as your income is below the limit.

When a Roth IRA is the right choice

A Roth works best when your current tax rate is lower than your expected retirement tax rate. This is most common for people in their 20s and 30s, people taking a year off or working part-time, and people whose income drops temporarily. If you're in the 12% federal tax bracket now but expect to be in the 22% or 24% bracket in retirement, the Roth saves you money over time.

A Roth is also useful if you want flexibility. You can withdraw your contributions (the money you put in) at any time without penalty or taxes. Only the earnings — the investment gains — are locked until 59½. This makes a Roth a partial emergency fund, though it's not a substitute for actual savings.

If you have a 401(k) through your employer, you can still open a Roth IRA. The two accounts have separate contribution limits and separate income limits, so having one doesn't prevent you from having the other.

When a traditional IRA or 401(k) makes more sense

If you're in a high tax bracket now and want to reduce your taxable income this year, a traditional IRA or 401(k) is better. You deduct the contribution from your income, which lowers your tax bill immediately. This is especially valuable if you're self-employed, have a large bonus, or are in the 24% federal bracket or higher.

A traditional IRA also makes sense if your income is above the Roth limit. You can still contribute to a traditional IRA regardless of income, though the deduction phases out at higher incomes. If you have no 401(k) at work and your income is above the Roth limit, a traditional IRA is often your only tax-advantaged retirement savings option.

If you expect to be in a lower tax bracket in retirement — because you plan to work part-time, live on less, or draw down savings slowly — a traditional account is the better choice. You'll pay taxes on withdrawals at a lower rate than you would have paid on the contribution.

Income limits and contribution caps for 2024

For 2024, you can contribute up to $7,000 to a Roth IRA if you're under 50, or $8,000 if you're 50 or older. You must have at least that much in earned income to contribute the full amount. If you earned $4,000 this year, you can only contribute $4,000.

The income limit depends on your filing status. If you file as single, you can contribute the full amount if your modified adjusted gross income is below $146,000. The contribution phases out between $146,000 and $161,000, and you cannot contribute at all above $161,000. If you're married filing jointly, the phase-out range is $230,000 to $240,000. If you're married filing separately, the limit is much lower: $0 to $10,000.

These numbers change each year. Check the IRS website or your brokerage before you contribute to confirm the current limits.

How to open a Roth IRA and make your first contribution

You open a Roth IRA through a brokerage — a financial company that holds your money and lets you invest it. Common brokerages include Vanguard, Fidelity, Charles Schwab, and Betterment. You can also open one through a bank, though banks typically offer fewer investment options.

The process takes 10 to 20 minutes online. You'll provide your name, Social Security number, address, and employment information. The brokerage will ask how you want to invest the money — in a mix of stocks and bonds, in a target-date fund that adjusts automatically as you age, or in individual stocks or funds. If you're unsure, a target-date fund is a simple starting point.

Once the account is open, you transfer money from your bank account to the Roth. You can do this by electronic transfer (usually free and takes 1 to 3 business days) or by check. You then instruct the brokerage how to invest that money. You can contribute anytime during the year, but you have until the tax filing deadline (usually April 15 of the following year) to contribute for the prior year.

What happens if your income rises above the limit

If your income exceeds the Roth limit in a given year, you cannot contribute that year. You don't lose the account or any money already in it — you simply cannot add new money. The money already there continues to grow tax-free.

Some people use a "backdoor Roth" strategy when their income is too high. You contribute to a traditional IRA (which has no income limit), then immediately convert it to a Roth. This works only if you have no other traditional IRA balances. If you do, the conversion becomes complicated and may trigger unexpected taxes. Consult a tax professional before attempting a backdoor Roth.

Penalties and rules for early withdrawal

You can withdraw your contributions at any time without penalty or taxes. If you contributed $5,000 and it grew to $6,000, you can withdraw the $5,000 with no consequences. The $1,000 in earnings stays in the account.

If you withdraw earnings before age 59½, you owe income tax on the earnings plus a 10% penalty — unless an exception applies. Exceptions include disability, medical expenses over 7.5% of your income, and first-time home purchase (up to $10,000 lifetime). If you've had the Roth for at least five years and are 59½ or older, you can withdraw everything tax-free and penalty-free.

If you withdraw money before the five-year mark, even if you're over 59½, the earnings portion is taxed as ordinary income. The five-year clock restarts if you open a new Roth, though conversions from traditional IRAs have their own five-year rule.

Frequently Asked Questions

Can I have both a Roth IRA and a 401(k)?

Yes. They have separate contribution limits and separate income limits. You can max out both in the same year if you have the income and your income is below the Roth limit. Many people do this to save as much as possible for retirement.

What if I don't have earned income but my spouse does?

You can open a spousal Roth IRA if you file taxes jointly and your spouse has earned income. The contribution limit is still $7,000 (or $8,000 if 50+), and it counts against your spouse's income limit, not yours. Your spouse must have at least $14,000 in earned income for both of you to contribute the full amount.

Do I have to invest the money in stocks?

No. You can hold cash, bonds, mutual funds, target-date funds, or individual stocks. Most brokerages offer a money market fund or savings option that earns a small amount of interest. If you're unsure what to invest in, a target-date fund based on your expected retirement year is a simple option.

What if I contribute too much by mistake?

Contact your brokerage and ask them to remove the excess contribution. If you do this before the tax filing deadline, you typically owe no penalty. If you don't catch it, you'll owe a 6% excise tax on the excess for each year it sits in the account. The IRS allows you to correct this on your tax return.

Can I roll money from a 401(k) into a Roth IRA?

Yes, but you'll owe taxes on the amount converted. If you convert $50,000 from a traditional 401(k) to a Roth, that $50,000 is added to your income for the year, and you pay taxes on it at your current rate. This is called a Roth conversion and makes sense only if you expect higher tax rates later or have other reasons to pay taxes now.
