Traditional vs. Roth IRA: How US Individual Retirement Accounts Work

An IRA is a personal retirement account you open yourself, separate from any employer plan. Here is how the two main types differ.

An account you open yourself, not through an employer

Unlike a 401(k), which is sponsored by an employer, an Individual Retirement Account (IRA) is opened directly with a brokerage or bank by an individual, and anyone with earned income can generally contribute regardless of whether their employer offers a retirement plan.

Traditional IRA: tax break now, taxed later

Contributions to a Traditional IRA may be tax-deductible in the year you contribute, depending on your income and whether you or a spouse is also covered by a workplace plan; withdrawals in retirement are then taxed as ordinary income.

Roth IRA: no tax break now, tax-free later

Roth IRA contributions are made with after-tax money, so there is no upfront deduction, but qualified withdrawals of both contributions and earnings in retirement are generally tax-free.

One combined annual contribution limit

The IRS sets a single annual contribution limit that applies across all of your IRAs combined, whether you split contributions between a Traditional and a Roth IRA or put everything into one. This limit is periodically adjusted and includes a higher "catch-up" allowance for savers age 50 and older.

Roth IRA contributions phase out at higher incomes

Roth IRA eligibility phases out above certain modified adjusted gross income (MAGI) thresholds that differ by filing status, and the exact thresholds are adjusted periodically. Traditional IRAs have no income limit on the ability to contribute, though the tax deduction can be limited depending on income and workplace coverage.

Required withdrawals apply differently to each

Traditional IRAs are generally subject to required minimum distributions (RMDs) starting at a certain age set by current law, while Roth IRAs held by the original owner are not subject to RMDs during their lifetime under current rules.

Early withdrawal rules and exceptions

Withdrawing earnings before age 59Β½ generally triggers a 10% penalty plus income tax on a Traditional IRA, with a list of specific exceptions such as a first-time home purchase up to a lifetime cap. Roth IRAs allow withdrawal of your own contributions (not earnings) at any time without penalty, since you already paid tax on that money.

Which one is "better" depends on your tax situation

The core trade-off is timing: a Traditional IRA gives you a tax break today in exchange for taxable withdrawals later, while a Roth IRA gives up today's tax break for tax-free withdrawals later. A common rule of thumb some financial educators mention is that a Roth may favor people who expect to be in a higher tax bracket in retirement than they are now, and vice versa for a Traditional IRA, but this is general guidance, not individual advice.

An IRA and a 401(k) are not mutually exclusive

Many people contribute to both an employer 401(k) and a personal IRA in the same year, since they have separate contribution limits from each other. A common strategy mentioned in general financial education is to contribute enough to a 401(k) to capture any employer match first, then consider an IRA for additional retirement savings.

Frequently Asked Questions

What are the current IRA contribution limits?

The IRS adjusts the combined annual IRA contribution limit periodically, with an additional catch-up amount for those 50 and older. Always check the current year's figures directly on irs.gov rather than relying on a number from a previous year, since this page explains the mechanics rather than year-specific dollar amounts.

Can I contribute to an IRA if I already have a 401(k) at work?

Yes, having a workplace plan does not prevent you from opening and contributing to an IRA. It can, however, affect whether your Traditional IRA contribution is tax-deductible, depending on your income.

Is a Roth IRA the same as a Roth 401(k)?

No. Both share the same after-tax, tax-free-withdrawal concept, but a Roth IRA is a personal account with its own separate contribution limit and income restrictions, while a Roth 401(k) is an employer-sponsored option inside a 401(k) plan with the 401(k)'s own limits and no income restriction.
