Frequently Asked Questions

What is the Roth IRA contribution limit?

For 2024, you can contribute up to $7,000 per year to a Roth IRA, or $8,000 if you are age 50 or older. Contributions are limited by your earned income and subject to income phase-outs.

Who is eligible to contribute to a Roth IRA?

Single filers with a modified adjusted gross income (MAGI) below $146,000 can contribute the full amount. The contribution phases out between $146,000 and $161,000. Married filing jointly phases out between $230,000 and $240,000 (2024 limits).

When can I withdraw Roth IRA earnings tax-free?

Qualified withdrawals—meaning both the account must be at least 5 years old and you must be 59½ or older—are 100% tax-free and penalty-free. Contributions (not earnings) can be withdrawn at any time without penalty.

Is there a required minimum distribution for a Roth IRA?

No. Unlike traditional IRAs and 401(k) accounts, Roth IRAs have no required minimum distributions (RMDs) during the owner's lifetime, making them powerful estate-planning and wealth-transfer tools.

What is a backdoor Roth IRA?

High earners above the income limit can make a non-deductible traditional IRA contribution and then convert it to a Roth IRA—known as a backdoor conversion. The pro-rata rule may apply if you have other pre-tax IRA funds.

How does a Roth IRA compare to a 401(k)?

Both offer tax advantages, but a 401(k) has much higher contribution limits ($23,000 vs $7,000 in 2024) and may include employer matching. A Roth IRA offers more investment flexibility, no RMDs, and tax-free withdrawals. Ideally, use both.
