Key takeaways

  • The 2026 Roth IRA contribution limit is $7,500, or $8,600 if you are 50 or older, and the income phase-out starts at $153,000 for single filers.
  • Roth IRAs offer growth and qualified withdrawals free of federal income tax, in exchange for not deducting contributions the way you can with a traditional IRA.
  • You can withdraw contributions from a Roth IRA at any age, tax-free and penalty-free, but earnings in your Roth IRA have rules attached.
In this article

A Roth IRA is a retirement account you fund with money you have already paid tax on. You get no deduction going in, and in return the growth and your qualified withdrawals are not taxed coming out. For 2026 you can contribute $7,500, or $8,600 from age 50, as long as your income is under the limit.1

What is a Roth IRA?

A Roth IRA is an individual retirement arrangement created under Section 408A of the tax code. You open it yourself with a broker or bank, unlike a 401(k), which your employer sponsors. Roth IRA vs 401(k) compares the two and shows which to fund first.

A Roth IRA is an account that holds investments, not an investment itself. Opening the account and choosing what goes inside it are two separate decisions.

There are also two separate sets of rules, and mixing them up causes most of the confusion. One set decides whether you are allowed to put money in. The other decides whether your earnings come out tax-free.

How a Roth IRA works

A Roth IRA works by taking money you have already paid tax on, investing it, and letting qualified withdrawals leave without a federal tax bill.2 That is the whole mechanism.

The benefit comes from the taxes you do not pay along the way. In a taxable brokerage account, dividends and realized gains get taxed every year, and the money that leaves to pay that tax stops compounding. Inside a Roth, no money leaves to pay tax, so all of it keeps compounding.

Roth IRA vs traditional IRA

The difference between a Roth IRA and a traditional IRA is when you pay the tax, not how much you can save. A traditional IRA deducts your contribution now and taxes the withdrawal later. A Roth does the reverse.

 Traditional IRARoth IRA
Tax on contributionsDeductible if you qualifyNone, always after-tax
Tax on qualified withdrawalsTaxed as ordinary incomeNone
Income limit on contributingNo ceiling, though the deduction phases outYes, direct contributions phase out
Lifetime required minimum distributionsYesNo

Which one wins depends on your best guess about your own tax rate: higher now, or higher when you retire. There is no universal answer. The break-even point moves with where you expect your bracket to land, and our Roth vs traditional IRA comparison works out where yours falls.

4 reasons to open a Roth IRA

Tax-free growth, and what that is worth over 30 years

Contribute the 2026 maximum of $7,500 a year for 30 years at a 7% return and you would put in $225,000 and finish with roughly $708,000. About $483,000 of that is growth, and in a Roth none of it is taxed on the way out.

The same gain in a taxable account would face capital gains tax, which at 15% is roughly $72,000. That tax savings is the entire argument for a Roth IRA. It is also why the account type matters more than the investments you put in it.

No required minimum distributions in your lifetime

A Roth IRA has no required minimum distributions for as long as you are alive. A traditional IRA does the opposite: its RMD rules eventually force money out whether you need it or not.

Your Roth balance can keep compounding past the age when RMDs start for other accounts. This also makes a Roth the account you would rather leave to an heir. Inherited Roths do carry their own distribution rules.

Contributions come out at any time, for any reason

Contributions come out of a Roth IRA at any time, for any reason, because you already paid tax on them.3 There is no age requirement, no hardship test, and no explanation needed.

This is the part that surprises people who have been told retirement money is locked up. A Roth can double as an emergency reserve, provided you understand that the money you pull out is contribution, not earnings.

It hedges a tax rate you cannot predict

A Roth IRA hedges a tax rate nobody can predict, including you. Holding money in both a tax-deferred account and a tax-free one means you are not betting everything on one answer about brackets thirty years out.

If rates rise, your Roth withdrawals are unaffected. If rates fall, your traditional account comes out ahead. Owning both means you do not have to predict future tax rates.

Who can contribute to a Roth IRA in 2026?

Anyone with taxable compensation and income under the limits can contribute, at any age. Compensation means wages, salary, fees, tips, and net self-employment earnings, not investment income, pensions, or Social Security.

For 2026 the limit is $7,500, or $8,600 if you are 50 or over. The catch-up is $1,100, up from $1,000, and it is now indexed for inflation under SECURE 2.0 rather than fixed. That total is a combined cap across every traditional and Roth IRA you own, not a limit per account.

There is no age limit. Both a 16-year-old with a summer job and a 78-year-old who still works are equally eligible. A child with no earnings can't contribute, though a Trump account needs no earned income.

A spouse with little or no income can also fund a Roth IRA through the working spouse's earnings if you file jointly, subject to your combined compensation. If your income is over the limit, a backdoor Roth IRA is the route people use instead: a nondeductible traditional IRA contribution, converted to a Roth. If your 401(k) takes after-tax contributions, a mega backdoor Roth can move much more into Roth money each year.

2026 Roth IRA income limits

Filing statusFull contribution belowPhase-out rangeIneligible at or above
Single or head of household$153,000$153,000 to $168,000$168,000
Married filing jointly$242,000$242,000 to $252,000$252,000
Married filing separately, living with spousen/a$0 to $10,000$10,000

Inside the phase-out range you can still contribute a reduced amount. The married-filing-separately range is not inflation-adjusted and has sat at $0 to $10,000 for years.

When your contribution deadline falls

Your contribution deadline falls on the filing deadline the following April, not December 31, which gives you a window of about fifteen and a half months. So you can still make a 2026 contribution in early 2027.

One step matters more than it looks: you have to tell your broker which tax year the money is for. That designation is what starts your five-year clock, and the designation is easy to miss when you fund the account.

When can you withdraw from a Roth IRA?

You can withdraw contributions from a Roth IRA at any time. Earnings only come out tax-free when the withdrawal is qualified. Early retirees rely on the contribution rule, and the guide to the FIRE movement shows how they use it before 59½.

A withdrawal of earnings is qualified when two things are both true: your five-year clock has run, and you have hit a qualifying event. Those events are turning 59½, becoming disabled, death, or up to $10,000 toward a first home.

When your five-year clock starts

The clock starts on January 1 of the tax year your first Roth contribution was for, not the day you opened the account. That distinction can let your earnings qualify months sooner.

Contribute in April 2027 and designate it for 2026, and your clock started on January 1, 2026. You reach qualified status on January 1, 2031, four years and nine months after you paid.

You get one clock, not one per account. The clock runs from your first Roth IRA, and opening more Roth IRAs later does not restart it.

The order money comes out of a Roth IRA

Withdrawals follow a fixed order set by regulation, and all your Roth IRAs count as one for this purpose.4 Contributions come out first, then conversions oldest-first, then earnings last.

That ordering works in your favor. If you have contributed $30,000 and the account has grown by $12,000, a $10,000 withdrawal is entirely contribution: no tax, no penalty, nothing to report.

Penalty-free is not the same as tax-free

Penalty-free is not the same as tax-free, and people often confuse the two. An exception can waive the 10% early-withdrawal penalty without making the money untaxed.

Take earnings for a first home before your five years are up and the penalty is waived, but you still owe ordinary income tax on those earnings. The first-home exception is also capped at $10,000 over your lifetime, and it has never been indexed.

What happens if you contribute too much to a Roth IRA?

An excess contribution is money you put in over the limit, or money you put in when your income disqualified you. An excess contribution costs 6% of the excess for every year it stays in the account.5

There are three ways to fix an excess contribution. Withdraw the excess plus whatever it earned before the filing deadline, and the 6% tax does not apply.

The other two ways: recharacterize the excess as a traditional IRA contribution before the same deadline, or leave the excess in the account, pay the 6% once, and apply it to next year's unused contribution room.

Most excess contributions are not carelessness. They happen when a bonus or a strong Q4 pushes income past the phase-out after you already contributed in January. This is a good argument for funding a Roth once you can estimate your income for the year.

How to open a Roth IRA in 4 steps

Step 1: Choose a custodian

Choosing a custodian means comparing three things: fees, the investments available, and whether you will use the platform.

Those three factors often conflict, so read the details before you pick a custodian. Our Robinhood review works through what a self-directed broker costs and what it lets you hold, and our Empower review works through what a managed alternative charges to make those decisions for you. Our best Roth IRA accounts roundup compares eight custodians on fees, matches, and the cost to transfer out.

Step 2: Open the account

Opening the account takes a Social Security number or ITIN. Name your beneficiaries when you open the account rather than later.

Step 3: Fund it and designate the tax year

Funding the account is the step that starts your five-year clock. This is why the tax-year designation matters.

Step 4: Invest the money

Investing the money is a separate action from funding the account. The next section explains why.

Why your Roth IRA might be sitting in cash

Moving money into a Roth does not invest it. The money lands in a settlement account and stays there until you place a trade.

Leaving the money uninvested is the most common expensive mistake with a new Roth. There is no warning, no prompt, just a balance that is not growing. Check what your account is holding.

Work out what you need

A Roth IRA is one part of your retirement savings target. How much money do you need to retire turns a spending figure into a savings target, and the retirement calculator runs your own. If you are weighing whether to move existing traditional money across, the Roth conversion calculator prices the tax bill, and the RMD calculator shows what the accounts you are not converting will force you to withdraw later.

Frequently asked questions about Roth IRAs

Can I have both a 401(k) and a Roth IRA?

You can contribute to both a 401(k) and a Roth IRA in the same year, because the two limits are entirely separate. Being covered by a workplace plan can reduce what you may deduct on a traditional IRA, but workplace-plan coverage has no effect on your Roth IRA eligibility.

Do I have to report Roth IRA contributions on my tax return?

Roth IRA contributions do not go on your Form 1040, since they are not deductible and change nothing about the tax you owe this year. Your custodian reports them to the IRS on Form 5498. Keep your own running total anyway, because the order of withdrawals depends on that total decades later.

Does a Roth 401(k) have required minimum distributions?

A Roth 401(k) no longer requires lifetime distributions from the account owner. SECURE 2.0 made this change, which brought the Roth 401(k) in line with the Roth IRA. The exemption applies to you, not to whoever inherits the account. Beneficiaries still face their own post-death distribution rules.

What can I invest a Roth IRA in?

A Roth IRA can hold whatever your custodian offers, which for most brokerages means stocks, bonds, mutual funds, ETFs, and cash. The account is a tax wrapper, so the choice of investments is separate from the choice of account. Investment menus vary by custodian, so check before you open an account.

What happens to my Roth IRA if I change jobs?

Changing jobs does nothing to your Roth IRA, because you own the account, not your employer. There is no rollover to do and no deadline to meet. That is the practical difference between an IRA and a 401(k) when you leave a company.

Can I lose money in a Roth IRA?

You can lose money in a Roth IRA, because the account holds real investments that rise and fall. The tax treatment protects your returns from being taxed; it does not protect your balance from the market. How your balance changes depends on what you chose to hold.
