You can put gifted money into a Roth IRA, but only up to the amount you earned from work that year, and only if your income falls under the Roth eligibility ceiling. The IRS doesn’t care whether the cash came from a paycheck, a birthday card, or a wedding envelope. What matters is that your taxable compensation for the year is at least as large as what you deposit. For 2026, the contribution cap is $7,500 if you’re under 50 and $8,600 if you’re 50 or older.
Your Earned Income Sets the Ceiling
This is the rule that trips people up. Your Roth contribution can’t exceed your taxable compensation for the year.1Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs If someone gives you $7,500 but you only earned $4,000 from a part-time job, $4,000 is your maximum contribution. The gift is just the funding source. It never counts as compensation itself.
Qualifying compensation includes wages, salaries, tips, commissions, and net self-employment earnings.2eCFR. 26 CFR 1.408A-3 – Contributions to Roth IRAs Two less obvious categories also count: nontaxable combat pay for military members serving in a combat zone, and taxable alimony received under a divorce decree finalized before 2019.3Internal Revenue Service. Miscellaneous Provisions – Combat Zone Service Interest, dividends, rental income, pension payments, and Social Security benefits do not qualify.
The practical consequence: a retiree who receives a generous cash gift but has no earned income cannot contribute anything to a Roth IRA that year, regardless of how much they received. The same applies to a college student living on scholarships and gifts. If there’s no W-2 or self-employment income, the Roth door is shut for that tax year.
Spousal IRA When One Spouse Doesn’t Work
Married couples get an important exception. Under the Kay Bailey Hutchison Spousal IRA rule, a non-working spouse can contribute to a Roth IRA based on the working spouse’s compensation, as long as you file a joint return.4Internal Revenue Service. Publication 590-A, Contributions to Individual Retirement Arrangements (IRAs) The working spouse just needs enough combined income to cover both contributions.
This matters when the gift recipient is a stay-at-home parent or a spouse between jobs. They can still deposit gift money into their own Roth IRA, provided the couple’s joint compensation supports both contributions. For 2026, the working spouse would need at least $15,000 in earned income to allow both spouses to max out at $7,500 each, or $17,200 total if both are 50 or older.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits
2026 Contribution Limits
No matter how large the gift, the annual cap on Roth contributions is fixed. For 2026:
- Under age 50: $7,500
- Age 50 or older: $8,600, which is the base $7,500 plus a $1,100 catch-up contribution
These caps apply across all your traditional and Roth IRAs combined.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits If you put $3,000 of the gift into a traditional IRA, only $4,500 can go into your Roth (assuming you’re under 50). Your actual ceiling for the year is the lower of the dollar cap or your earned compensation.
Income Phase-Outs Can Block the Contribution
Even with plenty of earned income, higher earners face reduced or eliminated Roth IRA eligibility based on modified adjusted gross income (MAGI). For 2026:6Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single or head of household: full contribution below $153,000; reduced from $153,000 to $168,000; no direct contribution at $168,000 or above
- Married filing jointly: full contribution below $242,000; reduced from $242,000 to $252,000; no direct contribution at $252,000 or above
- Married filing separately while living with a spouse: phase-out runs from $0 to $10,000, which is essentially a total bar
Within the phase-out band, your allowed contribution shrinks proportionally. Above the top of the range, you can’t make a direct Roth contribution at all, no matter how much gift money is sitting in your checking account. Contributing anyway triggers a 6% excise tax on the excess for every year it stays in the account.7Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts
The Backdoor Roth for High Earners
If your income exceeds the Roth phase-out ceiling, you aren’t permanently locked out. The backdoor Roth strategy lets you contribute to a traditional IRA, which has no income limit for contributions, and then convert those funds to a Roth. Congress removed the income limit on Roth conversions in 2010, and the workaround has been widely used since.
The basic steps: make a nondeductible contribution to a traditional IRA, then convert the balance to a Roth. You report the nondeductible contribution on IRS Form 8606, which tracks your after-tax basis so you’re not taxed twice on the same dollars.8Internal Revenue Service. About Form 8606, Nondeductible IRAs
Watch the pro rata rule. If you have other traditional IRA balances containing pre-tax money, whether from rollovers, past deductible contributions, or old employer plans moved into an IRA, the IRS treats all your traditional IRAs as a single pool when calculating the taxable portion of the conversion.9Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts You can’t cherry-pick just the after-tax dollars. If 90% of your combined traditional IRA balance is pre-tax, then 90% of whatever you convert is taxable income that year. For someone with large existing IRA balances, the tax hit can make the backdoor approach far less attractive than it first sounds.
What the Giver Should Know About Gift Tax
You don’t owe income tax on money someone gives you, and you don’t file anything related to the gift itself. Any tax burden falls on the giver. For 2026, a person can give up to $19,000 per recipient per year without filing a gift tax return. Married couples who elect gift-splitting can give up to $38,000 per recipient.
Gifts above the $19,000 annual exclusion require the giver to file IRS Form 709, but filing doesn’t necessarily mean owing tax.10Internal Revenue Service. Instructions for Form 709 The excess simply counts against the giver’s lifetime estate and gift tax exemption, which for 2026 is $15,000,000.11Internal Revenue Service. 12Internal Revenue Service. IRA Year-End Reminders A 2025 contribution can still be made until April 15, 2026, and a 2026 contribution can start as early as January 1, 2026. Marking the wrong year can create an accidental excess contribution in one year and a wasted opportunity in another.
If you mail a check, write your Roth IRA account number and the designated tax year in the memo line. Funds typically settle within a few business days. Once the money arrives, it sits as uninvested cash until you actually allocate it. Plenty of people make the contribution and then let it sit in a money market sweep for months without realizing it isn’t invested yet.
Fixing an Excess Contribution
If you overshoot (because you miscounted your earned income, misjudged your MAGI, or simply deposited more than the cap) you have a window to correct it before it gets expensive. Excess amounts left in the account get hit with the 6% excise tax every year they stay there.7Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts
The cleanest fix is to withdraw the excess plus any earnings it generated before your tax filing deadline, including extensions.4Internal Revenue Service. Publication 590-A, Contributions to Individual Retirement Arrangements (IRAs) Done on time, the IRS treats the contribution as if it never happened. Call your brokerage and ask for a “return of excess contribution” so the paperwork is coded correctly.
