An individual retirement account where contributions are made with after-tax dollars, allowing investments to grow tax-free and withdrawals in retirement to be tax-free.

Roth IRA — Fiscal Word Money Glossary

What a Roth IRA Means in Plain English

A Roth IRA is a retirement account with a specific tax deal: you pay taxes on the money going in, but everything that grows inside the account is yours tax-free forever. When you retire and start pulling money out, you owe the IRS nothing — not on the contributions, not on the decades of gains.

That’s a powerful promise. If you invest $6,000 at age 25 and it grows to $90,000 by retirement, you pay no taxes on that $84,000 in growth. With a traditional IRA or 401(k), you’d owe income taxes on every dollar you withdraw. The Roth flips the deal: pay a smaller tax bill now, skip the bigger one later.

The account is named after Senator William Roth, who pushed for its creation in the late 1990s. It’s an individual account — you open it yourself at a brokerage like Fidelity, Vanguard, or Schwab, independent of any employer. You control which funds you own.

How a Roth IRA Works

The 2024 limits: you can contribute up to $7,000 per year ($8,000 if you’re 50 or older). But there are income limits — this is a benefit the IRS restricts as you earn more. For single filers in 2024, contributions phase out between $146,000 and $161,000 of income; for married filing jointly, the phase-out runs $230,000 to $240,000. Above those limits, you can’t contribute directly.

High earners have a workaround: the backdoor Roth. You make a non-deductible contribution to a traditional IRA (no income limit for contributions, just for deductions) and then convert it to a Roth. It’s legal, widely used, and worth exploring if you’re above the income threshold.

Withdrawal rules have two layers. Your contributions — the money you put in — can be withdrawn any time, at any age, without taxes or penalties. You already paid tax on it; it’s yours. Your earnings (the growth) must stay until age 59½ and must meet a five-year rule (your account must be at least five years old) to withdraw tax-free. Pull earnings early and you owe taxes plus a 10% penalty.

Why a Roth IRA Matters to You

Young people with lower incomes get the most out of a Roth IRA — and it’s precisely because they have time. You’re making your contribution in a relatively low tax bracket, then letting the money compound for 30, 35, 40 years, all sheltered from taxes. The math gets staggering: $7,000/year contributed for 35 years at 7% return grows to roughly $1,000,000 — and every penny of those gains is untaxed.

The Roth vs traditional question comes down to: what tax bracket are you in now vs. what will you be in at retirement? Roth wins if you expect higher taxes in retirement (either because your income will be higher or because tax rates rise). Traditional wins if you’re in a high bracket now and expect lower income in retirement.

Young people almost always benefit from Roth because they’re typically in low brackets early in their careers. As income grows, the calculus can shift.

Quick Example

At 28, you open a Roth IRA and contribute $6,000 in your first year. You’re in the 22% tax bracket, so you pay $1,320 in federal tax on that contribution (factored into your regular tax bill). The money goes into a total market index fund.

By age 65 — 37 years later — assuming 7% average annual return, that $6,000 has grown to roughly $83,000. You withdraw it all to help fund retirement. Tax owed: $0.

If you’d put the same $6,000 into a traditional IRA, you’d have gotten a ~$1,320 tax break upfront. But at 65, withdrawing $83,000 in a 24% bracket means a $19,920 tax bill. The Roth saved you nearly $20,000 over one year’s contribution.

Common Misconceptions

“I can’t touch my Roth IRA until I’m 59½.” Only the earnings are restricted. You can withdraw your actual contributions — not the growth — at any time without penalty. This makes a Roth IRA a reasonable emergency fund backstop in addition to a retirement account, though ideally you’d never touch it.
“If I make too much money, I can’t benefit from a Roth.” Income limits prevent direct contributions above certain thresholds, but the backdoor Roth strategy remains available to high earners. It’s more paperwork, but it works.
