If you've heard the phrase "Roth IRA" and wondered what the fuss is about, here's the short version: it's a retirement account where your money grows completely tax-free. Not tax-deferred — tax-free. You never pay taxes on the gains, dividends or withdrawals in retirement. For most young and middle-income earners, it's one of the best financial tools available.

Simple definition: A Roth IRA is a retirement savings account funded with after-tax money. Your contributions grow tax-free, and qualified withdrawals in retirement are 100% tax-free.

Roth IRA vs Traditional IRA: what's the difference?

With a Traditional IRA, you contribute pre-tax dollars (reducing your taxable income today) and pay taxes when you withdraw in retirement. With a Roth IRA, you contribute after-tax dollars (no immediate tax break) but pay zero taxes on withdrawal. If you expect to be in a higher tax bracket in retirement than you are today — which is true for most young workers — the Roth IRA wins.

2026 contribution limits

The IRS sets annual contribution limits. For 2026, you can contribute up to $7,000 per year ($8,000 if you're 50 or older). There are income limits to be eligible: for single filers the phase-out begins at $150,000 MAGI; for married filing jointly, at $236,000. Above those limits, contribution ability phases out completely.

The power of tax-free compounding

Imagine you invest $7,000/year in a Roth IRA from age 25 to 65, earning an average 8% annual return. By retirement you'll have contributed $280,000 — but your account will be worth approximately $1.9 million. And you owe zero taxes on any of it. With a Traditional IRA you'd owe taxes on every withdrawal, potentially giving up hundreds of thousands of dollars.

Other Roth IRA advantages

  • Flexible withdrawals: You can withdraw your contributions (not earnings) at any time, penalty-free. This makes it a useful backup emergency fund.
  • No required minimum distributions: Unlike a Traditional IRA, you're never forced to withdraw from a Roth IRA during your lifetime.
  • Estate planning: Roth IRAs are excellent wealth-transfer vehicles — beneficiaries also receive tax-free distributions.

How to open one

Open a Roth IRA with Fidelity, Vanguard or Charles Schwab — all offer zero account minimums and free trades. Choose a target-date retirement fund or a simple S&P 500 index fund to start. Contribute as much as you can each year, ideally automating a monthly deposit. The earlier you start, the more time compounding has to work.

Golden rule: Max out your employer 401(k) match first (it's free money), then max out your Roth IRA. After that, go back to maxing the 401(k).
