Roth IRA Income Limits and Phase-Out Rules

A Roth IRA income limit phase-out sets MAGI (modified adjusted gross income) thresholds above which your ability to make direct Roth IRA contributions is reduced or eliminated. Unlike traditional IRAs, where the deduction phases out, a Roth IRA prevents you from contributing directly at all once your income exceeds the upper limit.

The Core Limit

The Roth IRA income limit prevents contributions from being made directly to a Roth account once your MAGI (modified adjusted gross income) enters a specified range. Below the range, you can contribute the full annual limit. Inside the range, you can contribute a reduced amount. Above the upper limit, you cannot contribute directly to a Roth IRA at all.

This is entirely separate from the traditional IRA deduction phase-out. You can be ineligible to fund a Roth even if you are ineligible to deduct a traditional contribution—and vice versa.

MAGI for Roth Purposes

For Roth contributions, MAGI is generally your AGI plus certain add-backs:

• Traditional IRA contributions (deductible and nondeductible).
• Student loan interest.
• Passive loss deductions.
• One-half of self-employment tax.
• Foreign earned income exclusion.
• Foreign housing exclusion or deduction.

Consult IRS Publication 590-A to verify which items apply to your specific income.

2025 Phase-Out Ranges

The IRS adjusts brackets for inflation annually.

Single filer: If MAGI is below $146,000, you can contribute the full amount ($7,000 for those under age 50 in 2025). At $146,000 or above but below $161,000, you can contribute a reduced amount. At $161,000 or above, you cannot contribute directly.

Married filing jointly: Below $230,000, full contribution. Between $230,000 and $240,000, partial. Above $240,000, no direct contribution.

Married filing separately: This filing status is extremely restrictive for Roth contributions. If you are married filing separately and either spouse contributed to any IRA (traditional or Roth), the phase-out range is $0–$10,000. Most filers in this category are blocked from Roth contributions.

Calculating a Partial Contribution

If your MAGI falls inside a phase-out range, you can still contribute a portion. The formula is:

Allowed contribution = $7,000 × (Upper limit − MAGI) / Range width

Round up any amount that is not a whole dollar.

Example: A single filer earned $154,000 MAGI and wants to contribute to a Roth IRA.

• Upper limit: $161,000
• MAGI: $154,000
• Range: $161,000 − $146,000 = $15,000

Allowed contribution = $7,000 × ($161,000 − $154,000) / $15,000
Allowed contribution = $7,000 × $7,000 / $15,000
Allowed contribution = $7,000 × 0.467 = $3,267 (rounded up from $3,266.67)

The filer can contribute $3,267 but not more. Any excess is subject to a 6% excise tax if not withdrawn.

Nondeductible Conversions for High Earners

The Roth income limit applies only to direct contributions. If your income exceeds the limit, you can still gain Roth access through a backdoor Roth conversion:

1. Contribute to a nondeductible traditional IRA.
2. Immediately convert the balance to a Roth IRA.

The conversion is treated as a taxable event only to the extent the account has untilled pretax earnings, but the initial nondeductible principal moves to the Roth tax-free.

Critical caveat: If you already have other pretax IRA balances, the pro-rata rule forces you to pay income tax on a portion of the conversion. This complicates backdoor planning for anyone with existing traditional IRA funds. Use Form 8606 to track basis carefully.

Spousal Implications

If one spouse has income and the other does not, only the earner’s income determines whether the Roth is accessible. A nonworking spouse can contribute to a spousal Roth based on the working spouse’s filing status. However, if you are married filing separately, both spouses are treated as having the same MAGI for phase-out purposes, making the phase-out nearly impossible to navigate.

Comparison to Traditional IRA Phase-Out

The traditional IRA deduction phase-out and Roth income limits are separate:

• Traditional: Affects deductibility if you are an active participant in an employer plan.
• Roth: Always applies, regardless of whether you have an employer plan.

High earners often use nondeductible traditional contributions when Roth direct contributions are blocked, then track basis using Form 8606.

Coordination with Other Accounts

Roth contributions count against the combined $7,000 annual limit for all IRAs (traditional, SEP, SIMPLE, and Roth) in the same year. If you contribute to a traditional IRA and a Roth IRA in the same year, your total cannot exceed $7,000. Income limits do not restrict contributions to employer plans like a Roth 401(k), which has no income threshold.
