How money moves in and out of a Roth IRA

A Roth IRA is a retirement savings account where you contribute money that has already been taxed, and then the money grows tax-free inside the account. When you withdraw money in retirement, you pay no tax on the growth — only on the original contributions you put in, which you can always take out without penalty.

The basic flow is straightforward: you deposit after-tax dollars, choose investments (stocks, bonds, mutual funds, or keep it in cash), and those investments grow over decades. The IRS does not tax the earnings while they sit in the account, and does not tax them when you withdraw them after age 59½, as long as the account has been open for at least five years.

This is the opposite of a traditional IRA, where contributions may be tax-deductible upfront but withdrawals in retirement are fully taxable. With a Roth, you pay the tax bill now and never again.

Key Takeaways

  • You fund a Roth IRA with money you have already paid income tax on, and the account grows tax-free for decades.
  • Withdrawals of your original contributions can be taken out at any time without tax or penalty, but earnings cannot be touched before age 59½ without a 10 percent penalty and income tax.
  • You must have earned income in the year you contribute, and contribution limits are set by the IRS and change yearly based on inflation.
  • The five-year rule means your account must be open for at least five tax years before you can withdraw earnings tax-free, even after age 59½.
  • Income limits determine whether you can contribute the full amount, a reduced amount, or nothing at all in a given year.

Who can contribute and how much per year

To contribute to a Roth IRA, you must have earned income — wages from a job, self-employment income, or taxable alimony. You cannot fund a Roth with investment returns, rental income, or Social Security. The amount you earn that year sets a ceiling on how much you can contribute.

The IRS sets an annual contribution limit that changes each year. For 2024, the limit is $7,000 if you are under age 50, and $8,000 if you are 50 or older (the extra $1,000 is called a catch-up contribution). These limits apply across all IRAs combined — if you have both a Roth and a traditional IRA, your total contributions to both cannot exceed the yearly limit.

Your ability to contribute at the full amount depends on your income. The IRS phases out Roth contributions for higher earners, meaning you can contribute less or nothing at all once your income crosses a threshold. These thresholds vary by filing status and change yearly. If you earn above the phase-out range, you cannot contribute directly to a Roth that year, though other strategies exist (such as the backdoor Roth conversion, which is a separate process).

How the five-year rule works

The five-year rule is a timing requirement that applies separately to contributions and conversions. For contributions you make directly to your Roth, the rule means your account must be open for at least five tax years before you can withdraw earnings tax-free and penalty-free after age 59½.

The five-year period starts on January 1 of the year you make your first contribution. If you open a Roth in March 2024 and contribute, the five-year clock begins January 1, 2024. By January 1, 2029, the five years have passed. After that date, once you turn 59½, you can withdraw earnings without tax or penalty.

If you withdraw earnings before the five years are up, you owe income tax on those earnings plus a 10 percent early withdrawal penalty — even if you are over 59½. Your contributions themselves are never subject to this rule; you can always pull out what you put in, whenever you want, with no tax or penalty.

What happens to your money while it grows

Once money is in your Roth IRA, you choose how to invest it. Most Roth accounts are held at a brokerage (Fidelity, Vanguard, Charles Schwab, or others) or a bank, and you can select from stocks, bonds, mutual funds, exchange-traded funds (ETFs), or simply leave it in a money market fund or savings option offered by your provider.

All growth — whether from dividends, interest, or capital gains — accumulates tax-free inside the account. If you buy a stock for $1,000 and it grows to $5,000, you owe no tax on that $4,000 gain while it sits in the Roth. You also do not owe tax if you sell that stock at a profit and reinvest the money into something else. This tax-free compounding is the core advantage of a Roth over a regular taxable brokerage account.

You can move money between investments within your Roth as often as you want without triggering any tax. You can also transfer your Roth from one provider to another (called a trustee-to-trustee transfer) without tax consequences. The only restriction is that you cannot contribute more than the yearly limit, regardless of how much you trade or how much your account grows.

Withdrawals before retirement and the exceptions

Before age 59½, you can withdraw your contributions anytime, tax-free and penalty-free. This is a major flexibility advantage of the Roth. If you contributed $50,000 over ten years and your account is now worth $75,000, you can pull out the $50,000 without any tax bill or 10 percent penalty.

Withdrawing earnings before 59½ normally triggers both income tax and a 10 percent early withdrawal penalty. However, the IRS allows penalty-free (but not tax-free) early withdrawals of earnings in specific situations: a first-time home purchase (up to $10,000 lifetime), may have access to education expenses, certain medical costs, and a few others. Even in these cases, you still owe income tax on the earnings withdrawn.

If you have both contributions and earnings in your account and you withdraw before 59½, the IRS assumes you are taking out earnings first (under the "pro-rata rule"), so you may owe tax and penalty even if you intended to withdraw only contributions. Keeping detailed records of how much you have contributed versus how much has grown helps you understand what you can safely withdraw.

Tax-free withdrawals in retirement

Once you turn 59½ and your Roth has been open for at least five tax years, you can withdraw as much as you want, whenever you want, with no tax owed. This includes all earnings. There is no required minimum distribution (RMD) — the IRS does not force you to take money out at any age, so your account can keep growing tax-free for as long as you live.

This is a sharp contrast to traditional IRAs and 401(k)s, where the IRS requires you to start taking distributions at age 73 (as of 2023, under current law). With a Roth, you have complete control over the timing and amount of withdrawals, which gives you flexibility to manage your tax situation in retirement.

If you die before withdrawing the money, your heirs inherit the Roth and can withdraw it tax-free (though they must follow distribution rules that depend on their relationship to you and the year of your death). The tax-free growth and tax-free inheritance make a Roth particularly valuable for building wealth to pass on.

Income limits and phase-outs

The IRS restricts who can contribute to a Roth based on Modified Adjusted Gross Income (MAGI). The phase-out ranges change yearly and depend on your filing status (single, married filing jointly, married filing separately, or head of household).

If your MAGI falls below the phase-out range, you can contribute the full amount. If it falls within the range, you can contribute a reduced amount (calculated by the IRS). If it exceeds the upper end of the range, you cannot contribute directly to a Roth that year. These limits exist to prevent high earners from using Roths as a primary wealth-building tool, though workarounds like backdoor conversions exist for those above the limit.

Because limits change yearly, it is worth checking the current year's threshold before you contribute. Your brokerage or tax preparer can tell you whether you are within the range for your filing status.

Frequently Asked Questions

Can I withdraw my contributions anytime without penalty?

Yes. Your contributions can be withdrawn at any age, at any time, with no tax or penalty. Only earnings are subject to the age 59½ rule and the five-year rule. Keep records of how much you contributed versus how much your account has grown so you can prove to the IRS what portion is contributions if you withdraw before 59½.

What is a backdoor Roth and when would I use it?

A backdoor Roth is a strategy for high earners who exceed the income limit. You contribute to a traditional IRA (which has no income limit), then immediately convert it to a Roth and pay tax on the conversion. This is legal but complex; consult a tax professional before attempting it, especially if you already have traditional IRA balances.

Do I have to take money out of my Roth at a certain age?

No. Unlike traditional IRAs and 401(k)s, Roths have no required minimum distributions during your lifetime. Your money can stay in the account and grow tax-free indefinitely. This makes a Roth useful if you do not need the money in retirement or want to leave it to heirs.

What happens if I do not meet the five-year rule?

If you withdraw earnings before the five-year period ends, you owe income tax on those earnings plus a 10 percent early withdrawal penalty. Your contributions are never subject to this penalty. The five-year clock resets if you close the account and reopen it later.

Can I have both a Roth IRA and a traditional IRA?

Yes, but your total contributions to both accounts in a single year cannot exceed the annual limit. If you contribute $4,000 to a Roth, you can contribute only $3,000 to a traditional IRA that year (assuming the limit is $7,000). Contributions to both are counted together toward the yearly cap.
