Who Should Use a Roth IRA

The plain answer

A Roth IRA tends to fit people who are eligible to contribute and expect their marginal tax rate on withdrawals to be higher than their marginal tax rate today. You pay tax before the contribution, receive no deduction, and can take qualified withdrawals tax-free.

That is a tax-rate tradeoff, not a rule that Roth is always better. A higher current tax rate than the rate you expect later can make an eligible Traditional IRA deduction more valuable.

How it actually works

Direct Roth IRA contribution eligibility phases out as modified adjusted gross income rises. For 2026, the phaseout ranges are:

• Single filers: $153,000 to $168,000
• Married filing jointly: $242,000 to $252,000

Below the applicable range, you may make the full contribution if you otherwise qualify. Within the range, your allowed contribution is reduced. At or above the end of the range, you cannot contribute directly to a Roth IRA for that year.

Your limit also depends on earned income and contributions to any Traditional IRAs. Read IRA contribution rules before contributing.

What this means for you

A Roth IRA may fit when:

• Your current marginal tax rate is relatively low and you expect a higher rate when you withdraw the money.
• You qualify to contribute directly under the income rules.
• You value qualified tax-free withdrawals and can leave earnings invested for retirement.
• You have already handled more urgent priorities in the order of operations for your money.

A Roth IRA may be less compelling when your current marginal tax rate is higher than the rate you reasonably expect later, especially if you qualify for a valuable Traditional IRA deduction. Compare that case with who should use a Traditional IRA.

Common mistakes

• Calling Roth automatically better because qualified withdrawals are tax-free.
• Comparing tax rates without distinguishing your marginal rate today from the rate that may apply to withdrawals later.
• Using gross income instead of modified adjusted gross income for the eligibility test.
• Missing the phaseout range and making an excess contribution.
• Forgetting that Traditional and Roth IRA contributions share one annual limit.
