Every year, a significant number of dual-income couples discover they can’t contribute to a Roth IRA — not because they made a mistake, but because they earned too much. The income limits on Roth IRA contributions are real, they’re not obvious, and the rules around what happens when you exceed them are genuinely confusing. This article gives you the plain-English version of exactly what those limits are, how they apply to married couples filing jointly, and what your options are if you’re over the line.
The Core Numbers — What the Limits Actually Are
Roth IRA contributions phase out based on Modified Adjusted Gross Income (MAGI). For married couples filing jointly, the phase-out range currently sits roughly between $230,000 and $240,000, though these numbers adjust annually for inflation — always verify the current year’s figures with IRS Publication 590-A or at IRS.gov before contributing.
Here’s what that phase-out means in practice:
- Below the lower threshold: you can contribute the full annual limit ($7,000 per person, or $8,000 if you’re 50 or older)
- Within the phase-out range: your contribution limit is reduced proportionally
- Above the upper threshold: you can’t contribute to a Roth IRA directly at all
So a married couple with a household MAGI of $218,000 — which is what the question in our title asks about — falls below the current phase-out range and both spouses can contribute the full amount, assuming each spouse has at least that much in earned income. That’s the good news. A couple at $235,000 would face partial phase-out. A couple at $245,000 can’t contribute directly at all.
The phase-out numbers above are approximate based on recent IRS adjustments. The IRS updates these thresholds each fall for the following tax year. Don’t rely on a number you read last year — look it up for the year you’re contributing to.
The MAGI Calculation — What Counts and What Doesn’t
MAGI for Roth IRA purposes isn’t quite the same as your W-2 income. It starts with your Adjusted Gross Income from your tax return and then adds back certain deductions — student loan interest, foreign earned income exclusion, and a few others. For most W-2 employees without unusual deductions, MAGI and AGI are very close to the same number.
What can reduce your MAGI before it’s compared against the Roth limit:
- Pre-tax 401(k) or 403(b) contributions — this is the big one. Every dollar you put into a traditional (pre-tax) workplace retirement account reduces your MAGI directly. A couple earning $248,000 who each max their traditional 401(k) at $23,500 reduces their MAGI by $47,000, bringing them to approximately $201,000 — well below the phase-out range. This is not a loophole; it’s the system working as designed.
- HSA contributions — if you’re covered by a high-deductible health plan, HSA contributions also reduce your MAGI. A family contribution to an HSA can shave another $8,000+ off your MAGI before the Roth comparison happens.
- Deductible IRA contributions — if you’re eligible for a deductible traditional IRA contribution (which has its own income limits when you’re covered by a workplace plan), those also reduce MAGI. This is rare at the income levels we’re discussing but worth knowing.
The practical implication: couples who are "over the limit" often discover they’re not, once they account for pre-tax retirement contributions they’re already making. Run your MAGI calculation before assuming you’re ineligible — many couples are closer to the Roth window than they think.
The Spousal IRA Rule Most Dual-Income Couples Miss
Both spouses can contribute to their own Roth IRA independently, as long as the household’s earned income is at least equal to the combined contributions. You can’t contribute more to IRAs than you have in earned income. This matters for couples where one spouse earns significantly less than the other — if one spouse earns $18,000 and the other earns $200,000, both spouses can still contribute the full $7,000 each ($14,000 combined), because the household’s combined earned income exceeds $14,000.
The one requirement that sometimes trips people up: the IRA is an individual account, not a joint account. Each spouse contributes to their own IRA in their own name. The contribution limits apply per person, not per household.
What to Do If You Exceed the Roth IRA Income Limit
Two main paths. Neither is ideal, but one is clearly better for most people in this situation.
Path 1: The Backdoor Roth IRA. This is the standard workaround for high earners who want to access Roth IRA benefits without running into the income limit. You contribute to a traditional IRA (non-deductible, which has no income limit), then immediately convert it to a Roth IRA. The conversion itself isn’t taxable because you contributed non-deductible dollars. This works cleanly — with one major exception called the Pro-Rata Rule, which bites people who have existing traditional IRA money. If you have $80,000 in a traditional IRA and you add $7,000 non-deductible and try to convert just the $7,000 to Roth, the IRS treats all your IRA money as a single pool and taxes the conversion proportionally. The Pro-Rata Rule is the reason many financial advisors tell people to roll existing traditional IRA funds into a 401(k) before executing a backdoor Roth — it eliminates the taxable portion of the conversion. How Roth conversions work and when to time them covers the mechanics in detail.
Path 2: Invest in a taxable brokerage account instead. If the backdoor Roth is complicated by existing traditional IRA balances, or if you’ve already maxed your 401(k) and HSA and just want somewhere for additional long-term savings, a taxable brokerage account is a perfectly legitimate vehicle. You lose the tax-free growth and withdrawal treatment of a Roth, but you gain flexibility (no contribution limits, no withdrawal rules, no penalty for accessing funds before 59½). For people who are well ahead on retirement savings and primarily want long-term investment growth, the tax drag in a taxable account on index funds is often modest — particularly if you hold tax-efficient investments like total market ETFs.
The Roth vs. Traditional Question Underneath This One
If you’re in the income range where the Roth limit matters — household income somewhere between $180,000 and $250,000 — you’re probably in the 22% or 24% federal tax bracket. The Roth vs. traditional question has a real answer at these income levels, and it’s not obviously one or the other.
The standard advice says: "You want Roth if you’ll be in a higher bracket in retirement; you want traditional if you’ll be in a lower bracket." That’s true but incomplete. Most people at this income level who are also saving aggressively are going to have substantial retirement income — Social Security plus large IRA and 401(k) distributions that push their RMDs into meaningful tax territory. For that profile, having some Roth money is genuinely valuable, even if you’re in the 22% bracket today. Tax diversification — some traditional, some Roth — is a real benefit, not just a hedge.
My own take, developed after years of watching people work through this in federal retirement planning: if you’re in the 22% bracket and have the option of Roth contributions without phase-out complications, take them. The after-tax simplicity of a Roth in retirement — no RMDs, no complicated tax calculations on withdrawals, no impact on Social Security taxation — is worth paying a modest tax premium today. The question of whether to choose Roth or traditional at 55 when you’re in the 22% bracket is covered in depth in our analysis of which IRA type makes more sense at 55 in the 22% bracket — the same logic applies at 45 or 50 if you’re just getting to this question.
The Excess Contribution Penalty — What Happens If You Accidentally Go Over
If you contribute to a Roth IRA and later discover your MAGI exceeded the limit, you’re not necessarily stuck with a permanent penalty. The IRS allows you to withdraw the excess contribution plus any earnings on it by the tax filing deadline (including extensions — usually October 15 of the following year). The earnings on the excess withdrawal are taxable and subject to a 10% penalty if you’re under 59½, but the principal itself comes back clean.
If you miss the deadline, the penalty is 6% per year on the excess amount for every year it stays in the account. That accumulates, which is why it’s worth being proactive. Your IRA custodian can process what’s called a "return of excess contribution" — it’s a specific transaction type that most custodians handle routinely. Call them when you realize the error rather than waiting to see if anyone notices.
The best way to avoid this: calculate your MAGI before contributing each year, not after. If your income is variable (bonus-dependent, commission-based, with stock vesting events), wait until you have a clear picture of your full year’s income before contributing in the fourth quarter, or contribute early in the following year when you file your taxes for the prior year — IRA contributions can be made up to the tax filing deadline and designated for the prior tax year.
The Roth IRA and Social Security — A Connection Worth Knowing
One underappreciated reason to have Roth assets in retirement: Roth IRA withdrawals don’t count as income for purposes of Social Security taxation. The IRS uses "combined income" (basically AGI plus half your Social Security benefit) to determine how much of your benefit is taxable — up to 85% of benefits become taxable above certain thresholds. Traditional IRA distributions and 401(k) withdrawals push that combined income number up. Roth withdrawals don’t.
For a retiree managing distributions carefully, pulling from Roth accounts in years when other income is high — large RMDs, capital gains events — can keep taxable income below the threshold that triggers additional Social Security taxation. This is a real, recurring benefit that compounds over a long retirement. How Social Security taxation works with a large IRA covers the combined income calculation in detail — worth reading if you’re building the kind of large retirement account balance that will generate significant RMDs.
The Tool to Use Before You Contribute
The IRS’s Interactive Tax Assistant at IRS.gov lets you enter your income and filing status to determine exactly what your Roth IRA contribution limit is for the current year. It takes under five minutes, uses current IRS data, and gives you a precise number rather than an estimate. Run this before contributing each year — it’s the cleanest way to avoid the excess contribution problem entirely.
For deeper context on how Roth IRAs fit into the full retirement picture, The Roth Revolution by James Lange is the most analytically rigorous book available on the Roth vs. traditional decision across different income levels and life stages. And for anyone building toward the income levels where these limits start mattering, The Millionaire Next Door by Thomas Stanley remains the most data-grounded look at how high-earning households actually build wealth over time — the Roth limit problem is, in many ways, a success problem.
