What Is a Roth IRA? A 2026 Guide to After-Tax Retirement Savings

what is a roth ira

What is a Roth IRA? A Roth IRA is an individual retirement account you fund with after-tax dollars, so qualified growth and withdrawals in retirement come out completely tax free.

Key Takeaways

  • A Roth IRA takes after-tax contributions: you get no upfront deduction, but qualified withdrawals are tax free, per the IRS.
  • For 2026 you can contribute up to $7,500, or $8,600 if you are age 50 or older (a $1,100 catch-up on top of the base limit), per the IRS 2026 limits.
  • Withdrawals of earnings are tax free only if they are qualified: the account has been open 5 years and you are at least age 59.5 (or meet another exception), per IRS Publication 590-B.
  • A Roth IRA has no required minimum distributions during the original owner’s lifetime, unlike a Traditional IRA (IRS).
  • In 2026 the ability to contribute phases out between $153,000 and $168,000 of MAGI for single filers and between $242,000 and $252,000 for married couples filing jointly (IRS).
  • Earn above those limits? A Roth conversion is the main way to move money into Roth, because conversions have no income limit.

What is a Roth IRA?

A Roth IRA is a type of individual retirement account you open and fund yourself with money you have already paid income tax on. In exchange for skipping the upfront deduction, the account grows tax free and qualified withdrawals in retirement are not taxed at all, according to the IRS.

The account is named after Senator William Roth, who sponsored the legislation that created it in 1997. It sits alongside the older Traditional IRA as one of the two main ways an IRA works, and the core difference between them is simple: when do you pay the tax, now or later?

With a Roth IRA you pay tax now, on the way in. That single design choice drives every feature that follows, from the way the money grows to the rules on getting it back out. Many retirees value the Roth precisely because it creates a pool of money that is not exposed to future tax rates.

How do Roth IRA contributions work in 2026?

Roth IRA contributions are made with after-tax dollars, which means you cannot deduct them on your tax return, the IRS confirms. This is the opposite of a deductible Traditional IRA contribution, and it is why a Roth does not reduce your taxable income in the year you contribute.

For the 2026 tax year, the contribution limit is $7,500, up from $7,000, according to the IRS 2026 announcement. If you are age 50 or older, a catch-up contribution of $1,100 raises your ceiling to $8,600 for the year.

That limit is a combined cap across all of your IRAs, not a per-account figure. You also need earned income (wages or self-employment income) at least equal to the amount you contribute. How much to put in often comes down to cash flow and your expected tax bracket in retirement.

How a Roth IRA works: the mechanics for 2026
Feature 2026 Roth IRA rule
Contribution type After-tax (not deductible)
Base contribution limit $7,500
Limit at age 50 or older $8,600 ($1,100 catch-up)
Tax on qualified withdrawals None (tax free)
5-year rule on earnings Applies
Lifetime RMDs (original owner) None
Income limit to contribute directly Yes (MAGI phase-out)

How does a Roth IRA grow and pay out tax free?

Inside the account, your contributions can be invested in funds, stocks, bonds, and similar holdings, and any dividends, interest, and gains compound without a yearly tax bill. The mechanics of how a Roth IRA grows are the same as any investment account, with one difference: the growth is sheltered from tax as it accrues.

The tax-free payout, though, comes with a condition. A withdrawal of earnings is only tax free if it is a qualified distribution, which under IRS Publication 590-B means the account has been open at least 5 years and you are at least age 59.5 (death, disability, and a first-home purchase up to a limit are the other qualifying triggers).

Your own contributions are treated differently. Because you already paid tax on them, you can withdraw contribution amounts at any time, tax free and penalty free. The 5-year rule and the age test apply to the earnings portion, not the money you put in. The full Roth IRA withdrawal rules and the details of the 5-year rule for Roth IRAs are worth understanding before you tap the account early.

Step 1 InAfter-tax dollarsYou contribute money you have already paid income tax on, so there is no deduction today.
Step 2 GrowTax-free growthDividends and gains compound with no annual tax drag inside the account.
Step 3 OutTax-free qualified withdrawalsAfter age 59 and a half and the 5 year rule, qualified withdrawals come out completely tax free.

Who can contribute to a Roth IRA in 2026?

Almost anyone with earned income can contribute to a Roth IRA, but the ability to contribute directly phases out at higher incomes. Eligibility is based on your modified adjusted gross income, or MAGI, and your tax filing status.

For 2026, the IRS sets the single and head-of-household phase-out range at $153,000 to $168,000 of MAGI. For married couples filing jointly, the range is $242,000 to $252,000. Below the range you can contribute the full amount, within the range your limit shrinks, and above it you cannot contribute directly at all.

Married filing separately is a special case: that phase-out range is not adjusted for inflation and stays at $0 to $10,000, per the same IRS release. Age is not a barrier, and there is no upper age cutoff, so the question of whether anyone can open a Roth IRA largely turns on earned income and these income limits.

How is a Roth IRA different from a Traditional IRA?

The Roth IRA and the Traditional IRA are mirror images on tax timing. A Traditional IRA contribution may be deductible now, grows tax deferred, and is taxed as ordinary income when you withdraw it. A Roth IRA gives no deduction now, grows tax free, and pays out tax free when qualified.

The other headline difference is required minimum distributions. A Traditional IRA forces withdrawals starting at your RMD age, while a Roth IRA does not require the original owner to take anything. For a fuller side-by-side, see Roth vs Traditional IRA.

Roth IRA vs Traditional IRA at a glance
Feature Roth IRA Traditional IRA
Contribution After-tax (no deduction) Often deductible
Growth Tax free Tax deferred
Qualified withdrawals Tax free Taxed as ordinary income
Lifetime RMDs None for original owner Required at RMD age
Direct income limit Yes (MAGI phase-out) No limit to contribute

Neither account is universally better; the right fit depends on whether you expect to be in a higher or lower tax bracket later. That trade-off is the heart of the question of whether a Roth IRA is worth it for a given saver.

Do Roth IRAs have required minimum distributions?

No. A Roth IRA has no required minimum distributions during the original owner's lifetime, and the IRS states plainly that you can leave amounts in the account as long as you live. A Traditional IRA, by contrast, forces taxable withdrawals once you reach RMD age.

This is one of the reasons the Roth structure is so useful for legacy and tax planning. Money that is never forced out can keep compounding tax free, and heirs generally inherit the account with favorable tax treatment. Retirees facing large Traditional IRA balances often look at Roth strategies for exactly this reason.

What if you earn too much to contribute directly?

If your income sits above the Roth IRA phase-out range, you cannot make a direct Roth contribution, but you are not shut out of Roth entirely. For higher earners, a Roth conversion is the main way in, because converting existing pre-tax funds to Roth has no income limit.

A conversion is different from opening and funding a new Roth account: it moves money you already hold in a Traditional IRA or workplace plan into a Roth, and you pay ordinary income tax on the converted amount in that year. That distinction, between converting existing pre-tax funds and making a fresh after-tax contribution, trips up many savers.

Because a conversion adds to your taxable income, retirees in a lower-bracket year often model whether spreading conversions over several years keeps them under a target bracket. A financial professional can help evaluate whether, and how much, to convert. This kind of Roth conversion planning weighs today's tax cost against a lifetime of tax-free growth.

Common misconceptions about the Roth IRA

A frequent misunderstanding is that all Roth withdrawals are automatically tax free. They are not: only qualified distributions of earnings escape tax, which is why the 5-year rule and the age 59.5 test matter. Your own contributions, however, always come out tax free because they were funded with after-tax money.

Another is that a Roth IRA and a Roth 401(k) are the same thing. They share the after-tax, tax-free-growth structure but differ on contribution limits, income rules, and (historically) RMD treatment. And a Roth IRA is not a substitute for a Roth conversion strategy; for many retirees, the two work together as part of a broader plan for tax-free retirement income.
