What Is Roth IRA?
A Roth IRA lets you invest after-tax dollars and withdraw everything tax-free in retirement. Learn Roth IRA rules, limits, and why it's the most powerful retirement account.
Definition
A Roth IRA is an individual retirement account where you contribute money that has already been taxed (after-tax dollars). The magic of the Roth IRA is that all growth and withdrawals in retirement are completely tax-free. You pay taxes once on the contribution, and then never again -- no matter how much the account grows.
For 2026, you can contribute up to $7,000 per year ($8,000 if age 50+) to a Roth IRA, as long as your modified adjusted gross income is below $161,000 (single) or $240,000 (married filing jointly). If you earn more, you can use the "backdoor Roth" strategy: contribute to a Traditional IRA and then convert it to a Roth.
Unlike Traditional IRAs and 401(k)s, Roth IRAs have no Required Minimum Distributions (RMDs). You are never forced to withdraw money, which means you can let it grow tax-free for as long as you like and even pass it to heirs. Additionally, you can withdraw your contributions (but not earnings) at any time without penalty, making the Roth IRA more flexible than other retirement accounts.
Real-World Example
At age 25, you open a Roth IRA and contribute $7,000 per year for 40 years. Invested in an S&P 500 index fund averaging 10% annually, your Roth IRA grows to approximately $3.4 million. You contributed a total of $280,000 over those 40 years. The remaining $3.1 million is pure investment growth -- and every dollar of it is tax-free. If that money were in a Traditional IRA instead, you would owe taxes on every withdrawal, potentially paying $600,000 or more in retirement taxes.
Why It Matters
The Roth IRA is widely considered the most powerful retirement account available to middle-class Americans. Tax-free growth over decades is extraordinarily valuable -- the longer your time horizon, the more valuable the tax-free benefit becomes. Young investors in particular should prioritize Roth contributions because they are likely in the lowest tax bracket they will ever be in. Every year you can contribute is a year of tax-free growth you can never get back.

Frequently Asked Questions
What is the income limit for a Roth IRA?
For 2026, the income phaseout begins at $146,000 for single filers and $230,000 for married filing jointly. Above $161,000 (single) or $240,000 (married), you cannot contribute directly but can use the backdoor Roth strategy.
What is a backdoor Roth IRA?
A backdoor Roth is a strategy where you contribute to a Traditional IRA (no income limit for contributions) and then convert it to a Roth IRA. This allows high earners to get money into a Roth despite income limits. Consult a tax professional for the details.
Can I withdraw from my Roth IRA before retirement?
You can withdraw your contributions (not earnings) at any time without penalty or taxes. Earnings withdrawn before age 59 1/2 and before the account is 5 years old may be subject to taxes and a 10% penalty.
Should I choose a Roth IRA or Traditional IRA?
If you expect to be in a higher tax bracket in retirement (common for young people), Roth is usually better. If you need the tax deduction now and expect lower taxes later, Traditional may be better. Many financial advisors recommend Roth for anyone under 40.
