Your income determines how much you can contribute to a Roth IRA each year
The IRS sets income limits that phase out your ability to contribute. If your income exceeds a certain threshold, you cannot contribute the full amount — and above a higher threshold, you cannot contribute at all. The limits change each year and depend on your filing status (single, married filing jointly, married filing separately, or head of household).
For 2024, if you file as single, the phase-out range is $146,000 to $161,000. If you file as married filing jointly, it is $230,000 to $240,000. If you are married filing separately, the range is $0 to $10,000 — which means almost no contribution is possible if you have any income. These numbers shift annually, usually upward by a few hundred dollars.
Your modified adjusted gross income (MAGI) is what counts, not your total income. MAGI includes certain deductions and exclusions that your regular income does not. For most people, MAGI is close to their adjusted gross income (AGI) from their tax return, but you should verify this with a tax professional if you have self-employment income, foreign income, or significant deductions.
Key Takeaways
- Income limits for Roth IRA contributions change every year and vary by filing status — single filers face different thresholds than married filers.
- If your MAGI falls within the phase-out range, you can contribute a reduced amount, not zero — the limit decreases gradually as income rises.
- Once your income exceeds the upper limit for your filing status, you cannot contribute to a Roth IRA directly, though a backdoor Roth conversion may still be an option.
- Your MAGI, not your gross income, determines whether you hit the limit — these can differ significantly depending on your income sources and deductions.
How the phase-out works if your income is in the range
If your MAGI falls between the lower and upper limit for your filing status, you do not lose all contribution room at once. Instead, the IRS calculates a reduced contribution amount using a formula. The reduction is proportional: the higher your income within the range, the lower your allowed contribution.
For example, if you file single in 2024 and your MAGI is $150,000, you are $4,000 into the $146,000–$161,000 phase-out range. The IRS divides your excess income by the width of the range ($15,000) and subtracts that fraction from the full contribution limit. If the full limit is $7,000, your allowed contribution would be reduced to roughly $5,133. Any amount that does not divide evenly is rounded up, so you may be able to contribute $100 even if the math suggests $99.50.
You do not have to calculate this yourself. When you open or contribute to a Roth IRA, your financial institution or tax software will ask for your MAGI and filing status and will tell you the maximum you can contribute. If you are unsure of your MAGI, a tax professional can calculate it from your tax return.
What happens if your income exceeds the upper limit
Once your MAGI exceeds the upper threshold for your filing status, you cannot make a direct contribution to a Roth IRA that year. For 2024, that means single filers earning over $161,000 and married joint filers earning over $240,000 are blocked from contributing directly.
This does not mean a Roth IRA is permanently closed to you. A backdoor Roth conversion is a legal strategy that allows higher earners to fund a Roth IRA indirectly. You contribute money to a traditional IRA (which has no income limit), then convert it to a Roth IRA. The conversion itself is taxable, but the money ends up in a Roth account. This strategy has rules and tax consequences, so consult a tax professional before attempting it.
Income limits by filing status for 2024
| Filing Status | Phase-Out Range | Cannot Contribute Above |
|---|---|---|
| Single | $146,000–$161,000 | $161,000 |
| Married Filing Jointly | $230,000–$240,000 | $240,000 |
| Married Filing Separately | $0–$10,000 | $10,000 |
| Head of Household | $146,000–$161,000 | $161,000 |
These limits apply to the tax year in which you make the contribution. If you contribute in early 2025 for the 2024 tax year, use the 2024 limits. The IRS publishes updated limits each October for the following year.
How to find your MAGI
Your MAGI is not a line item on your tax return — you have to calculate it or ask your tax preparer. Start with your adjusted gross income (AGI), which appears on your tax return. Then add back certain deductions the IRS specifies for Roth IRA purposes. These typically include student loan interest, IRA deductions, and certain foreign income exclusions.
For most W-2 employees with no self-employment income or foreign earnings, MAGI and AGI are the same. If you are self-employed, have rental income, or receive foreign earned income, your MAGI will likely differ. Your tax software or a tax professional can calculate this for you based on your specific situation.
What to do if you are close to the income limit
If your MAGI is near the phase-out range, you have a few options. First, confirm your exact MAGI with a tax professional — it may be lower than you think if you have deductions that reduce it. Second, if you are married and file separately, consider filing jointly if that is an option, since the joint limit is much higher. Third, if you exceed the limit, explore the backdoor Roth conversion strategy with a tax advisor.
You can also time your contribution strategically. If you know your income will drop in a future year, you might wait to contribute until then. Contributions can be made up until the tax filing deadline (usually April 15) for the prior year, so you have flexibility in when you fund your account.
Frequently Asked Questions
Does my spouse's income count toward my Roth IRA limit if we file separately?
No. If you file separately, only your own MAGI counts. However, the income limit for married filing separately filers is extremely low ($0–$10,000), so filing separately is rarely advantageous for Roth IRA purposes. Consult a tax professional about your specific situation.
Can I contribute to a Roth IRA if I have no earned income?
No. You must have earned income (wages, self-employment income, or taxable alimony) in the year you contribute. Passive income like investment returns or rental income does not count. Your contribution limit cannot exceed your earned income for that year, regardless of the income limit.
What if I contribute too much because I miscalculated my MAGI?
Contact your financial institution and request a return of the excess contribution plus any earnings on it. If you catch the error before filing your tax return, you can usually correct it without penalty. If you discover it after filing, you may owe taxes and a 6% penalty on the excess amount, so address it promptly.
Do income limits apply to Roth IRA conversions?
No. There is no income limit on converting a traditional IRA to a Roth IRA. This is why the backdoor Roth strategy works for high earners. However, the conversion itself is a taxable event, and you may owe taxes on the amount converted.
