What is a Roth IRA in plain English
A Roth IRA is a retirement savings account where you contribute money you've already paid income tax on. That money is then invested — typically in stocks, bonds, or mutual funds — and the investment growth is never taxed again, provided you follow the withdrawal rules. The tradeoff is upfront: you pay tax now, in exchange for tax-free withdrawals decades later. This contrasts with a traditional IRA, where you get a tax deduction today but pay income tax on every dollar you withdraw in retirement. For most Americans under age 50 earning less than $150,000, the Roth is the mathematically better choice.
The short answer (TL;DR)
A Roth IRA lets you contribute up to $7,000 in 2026 (or $8,000 if you're 50 or older) of after-tax income to an investment account. Your contributions can be withdrawn anytime, tax-free and penalty-free. Investment earnings can be withdrawn tax-free once you turn 59½ and have held the account for at least five years. Income limits apply: in 2026, single filers earning more than $165,000 and married filers earning more than $246,000 face reduced or eliminated contribution eligibility.
How Roth IRA contributions and withdrawals actually work
Contributions follow the calendar year, but you have until the April tax filing deadline of the following year to make them. So for the 2026 tax year, you can contribute through April 15, 2027. Each contribution is tracked separately by tax year, and the IRS allows you to withdraw your own contributions at any age without tax or penalty — a powerful flexibility no other retirement account offers. The earnings portion is treated differently. To pull earnings out tax-free, you must be at least 59½ years old and have held any Roth IRA for at least five years. Pull earnings out early and you'll owe income tax plus a 10% penalty, with limited exceptions for first-home purchases, disability, and qualified education expenses.
Roth IRA vs traditional IRA: the key differences
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax treatment on contribution | After-tax (no deduction) | Pre-tax (deductible if eligible) |
| Tax treatment on withdrawal | Tax-free in retirement | Taxed as ordinary income |
| 2026 contribution limit (under 50) | $7,000 | $7,000 |
| Income limit for 2026 | Phases out $165K–$180K single | No income limit to contribute |
| Required minimum distributions | None during your lifetime | Required starting age 73 |
| Early withdrawal of contributions | Allowed anytime, no penalty | 10% penalty before age 59½ |
A real-world example: how a Roth IRA compounds
Consider a 30-year-old who contributes the full $7,000 to a Roth IRA each year until age 65, invested in a low-cost S&P 500 index fund averaging 7% annual returns. Total contributions over 35 years equal $245,000. The account balance at age 65 would be approximately $1,032,000 — and every dollar is withdrawable tax-free. The same $245,000 contributed to a traditional IRA would also grow to $1,032,000, but withdrawals would be taxed at the retiree's marginal income rate. At a 22% rate, that's $227,000 in lifetime taxes the Roth saver avoids.

Frequently asked questions
What is a Roth IRA's biggest advantage over a 401(k)?
Tax-free withdrawals and no required minimum distributions are the two clearest advantages. A traditional 401(k) forces you to start taking taxable distributions at age 73, regardless of whether you need the money. A Roth IRA lets you leave the entire balance untouched for life and pass it to heirs. The 401(k) wins on contribution limits ($23,000 in 2026 vs $7,000) and employer match, so most savers should use both.
Can I contribute to a Roth IRA if I'm self-employed?
Yes, as long as your modified adjusted gross income is below the phaseout thresholds. Self-employment income counts as earned income for Roth eligibility. Self-employed savers may also consider a SEP IRA or Solo 401(k) alongside a Roth IRA, since those accounts allow much higher contribution limits and can be opened in addition to a personal Roth.
What happens if I contribute too much to a Roth IRA?
Excess contributions face a 6% IRS penalty for each year they remain in the account. You can fix the problem by withdrawing the excess plus any earnings before your tax filing deadline. If you discover the excess after the deadline, you can apply it to a future year's contribution limit, but the 6% penalty stacks each year until corrected.
Is a Roth IRA better than a brokerage account?
For retirement savings, almost always yes. Investment earnings in a regular brokerage account are taxed on dividends each year and on capital gains when you sell. A Roth IRA shelters all of that growth from tax. The only reason to choose a brokerage account first is if you've maxed your Roth, or if you need access to the funds before age 59½ for non-emergency reasons.
