Roth IRA Contribution Limits: Phase-Outs, Spousal Rules, and Penalties

For the 2026 tax year, the Roth IRA contribution limits are $7,500 if you’re under 50 and $8,600 if you’re 50 or older, thanks to a $1,100 catch-up allowance.¹ Two conditions decide whether you can actually contribute that much: you need earned income at least equal to your contribution, and your Modified Adjusted Gross Income has to fall below the phase-out range for your filing status.

The Dollar Caps and How They’re Shared

The $7,500 base limit rose from $7,000 in 2024 and 2025, and the catch-up amount for people 50 and older increased for the first time in years, from $1,000 to $1,100.¹ The adjustment mechanism is written into 26 U.S.C. § 219, which ties the base IRA cap to cost-of-living changes.²

These figures apply to all your IRAs combined. If you have both a traditional IRA and a Roth IRA, the $7,500 ceiling covers your total contributions across both accounts, not each one separately.³ Split any way you like between the two account types, but the sum can’t exceed the annual cap.

You also have more time to fund the account than most people realize. Contributions for the 2026 tax year can be made any time from January 1, 2026, through the tax filing deadline in mid-April 2027.⁴ Missing December 31 is not the end of the window.

You Need Earned Income

This is the gate people overlook most often. You can only contribute to a Roth IRA if you have taxable compensation: wages, salary, tips, self-employment income, or similar earnings from work you actually performed.⁵ Investment income, rental income, pension payments, and dividends don’t count.

Your contribution is capped at the lesser of the statutory limit or your taxable compensation for the year.³ Earn $4,000 from a part-time job and nothing else, and $4,000 is your ceiling for the year even though the statute allows $7,500. Someone fully retired and living on Social Security and investment gains generally cannot make any Roth contributions at all, regardless of wealth.

Income Phase-Outs by Filing Status

Even with earned income, your MAGI can partially or completely block you from contributing. MAGI starts with your adjusted gross income and adds back certain deductions like the student loan interest deduction, foreign earned income exclusions, and IRA deductions.⁶ For most W-2 employees without foreign income, MAGI and AGI are the same number.

For 2026, the ranges are:

Single or head of household: full contributions allowed below $153,000 MAGI, reduced contributions between $153,000 and $168,000, and nothing above $168,000.¹
Married filing jointly: full contributions below $242,000, reduced contributions between $242,000 and $252,000, and nothing above $252,000.¹
Married filing separately, if you lived with your spouse at any point during the year: the phase-out starts at $0 and ends at just $10,000. Any MAGI above $10,000 cuts you off from direct contributions entirely.⁷

If your income lands inside a phase-out range, you calculate a reduced contribution limit rather than losing access entirely. Publication 590-A has the worksheet; the basic logic is that the closer your MAGI is to the top of the range, the less you can put in.⁵

Spousal Contributions for Single-Income Couples

If one spouse works and the other doesn’t, the working spouse can fund a Roth IRA for the nonworking spouse, as long as the couple files jointly and the working spouse’s compensation covers both contributions. Each spouse can contribute up to the full annual limit into their own separate Roth IRA, so a couple could put away up to $15,000 combined in 2026, or $17,200 if both are 50 or older.³ The married-filing-jointly phase-out applies to both accounts.

A stay-at-home parent who earns nothing can still build a full Roth IRA entirely funded by their spouse’s paycheck.⁵

The Backdoor Roth for Income Above the Phase-Out

If your income exceeds the phase-out ceiling, you cannot contribute to a Roth IRA directly. A two-step workaround, often called the backdoor Roth, uses the fact that traditional IRA contributions have no income limit (only the deduction does), and there’s no income limit on converting a traditional IRA to a Roth.

The steps: contribute to a traditional IRA without claiming a deduction, then convert that balance to a Roth IRA. You report the nondeductible contribution on IRS Form 8606, which tracks your after-tax basis so you don’t get taxed twice.⁸ Because the money going in was already taxed and not deducted, the conversion itself is generally tax-free.

The catch is the pro-rata rule. If you have any pre-tax money in traditional, SEP, or SIMPLE IRAs, the IRS treats all of it as one pool and taxes the conversion proportionally. If 90% of your total traditional IRA balance is pre-tax and you convert $7,500, roughly $6,750 of that conversion is taxable. The cleanest backdoor conversions happen when you have zero pre-tax IRA balances. Rolling pre-tax IRA money into a workplace 401(k) before year-end can eliminate the problem, since the pro-rata calculation uses your December 31 balance.

Any gains between contribution and conversion are taxable, so most advisors recommend converting quickly, ideally within days.

Penalty for Contributing Too Much

Exceed the dollar cap or contribute when your income disqualifies you, and the IRS imposes a 6% excise tax on the excess amount. That penalty applies every year the excess stays in the account, not just once.⁹

You can avoid the penalty by withdrawing the excess contribution and any earnings it generated before your tax filing deadline, including extensions.⁴ The earnings you pull out are taxable income for the year and may also face the 10% early withdrawal penalty if you’re under 59½. Painful, but far better than a recurring 6% hit that compounds year after year.

This is where trouble usually starts when income unexpectedly jumps: a large bonus, a stock option exercise, or a side business profit that pushes MAGI above the phase-out range after you’ve already contributed. If your income is anywhere near the threshold, estimate your MAGI before you fund the account, not after.
