Yes, you can add money to a rollover IRA. The IRS treats it as a traditional IRA once your 401(k) or 403(b) funds land in it, so you can make new annual contributions up to $7,500 in 2026, or $8,600 if you are 50 or older.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Before you do, it’s worth knowing who qualifies, whether the deduction is available at your income, and what you give up by mixing new deposits with rolled-over funds.
Who Qualifies to Contribute
You need taxable compensation — earned income — during the year of the contribution. Wages, salaries, tips, bonuses, self-employment income, and professional fees qualify. Dividends, interest, rental income, and Social Security do not.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs)
Age is no longer a barrier. The SECURE Act repealed the old 70½ cutoff by amending 26 U.S.C. § 219(d)(1), so anyone with qualifying compensation can contribute at any age.3Office of the Law Revision Counsel. 26 USC 219 – Retirement Savings You can keep adding to a rollover IRA even while taking required minimum distributions, as long as you earn compensation that year.
If Your Spouse Is the Earner
Filing a joint return with a working spouse lets you contribute even without personal earned income. Each spouse can contribute up to the full annual limit, provided the couple’s combined contributions do not exceed the taxable compensation reported on the joint return.4Internal Revenue Service.

How Much You Can Add in 2026
For the 2026 tax year:
- Under 50: up to $7,500
- 50 or older: up to $8,600, which includes a $1,100 catch-up
The cap covers all of your traditional and Roth IRAs combined, not each account.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Put $3,000 into a Roth this year and, if you are under 50, no more than $4,500 can go into your rollover IRA for the same year. The balance you originally rolled in from an employer plan does not count against these annual caps.4Internal Revenue Service. Retirement Topics – IRA Contribution Limits
You have until the tax-filing deadline the following spring to make a contribution for the prior year. For 2026, that deadline is April 15, 2027.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs)
Whether Your Contribution Is Deductible
Deductibility turns on two things: whether you or your spouse participate in an employer-sponsored retirement plan, and your modified adjusted gross income. If neither of you is covered by a workplace plan, the full contribution is deductible regardless of income.
When you or your spouse is covered, the deduction phases out over these 2026 ranges:1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single filer covered by a workplace plan: $81,000 to $91,000
- Married filing jointly, contributing spouse covered: $129,000 to $149,000
- Married filing jointly, contributor not covered but spouse is: $242,000 to $252,000
- Married filing separately, covered by a workplace plan: $0 to $10,000
Above the top of your range, you cannot deduct any portion. You can still contribute, but the money goes in on a nondeductible, after-tax basis. Keep records of nondeductible contributions so you don’t pay tax on that portion again when you withdraw it in retirement.
What You Give Up by Mixing New Money With Rollover Funds
Adding personal contributions to a rollover IRA creates a commingled account. It’s legal, but it costs you flexibility in two places.
Moving the Money Back Into an Employer Plan
Some 401(k) and 403(b) plans only accept incoming rollovers from IRAs holding exclusively employer-plan money, sometimes called conduit IRAs. Mix in personal contributions and those plans may reject a rollover of the full balance. Each plan’s document controls what it accepts, so the rule varies by employer. If you might want to roll the money into a future employer’s plan, keep the rollover assets in a separate IRA and put new contributions somewhere else.
Bankruptcy Protection
Funds rolled over from a 401(k), 403(b), or 457 plan get unlimited bankruptcy protection under federal law.5Office of the Law Revision Counsel. 11 U.S. Code 522 – Exemptions Personal contributions to a traditional or Roth IRA are protected only up to an inflation-adjusted ceiling, which stood at $1,711,975 as of April 2025.6Federal Register. Adjustment of Certain Dollar Amounts Applicable to Bankruptcy Cases Once the two pools sit in the same account, proving which dollars came from the employer plan can get hard if a creditor claim comes up. A separate rollover IRA keeps the paperwork clean.
How to Deposit the Money
Getting the mechanics right at deposit time saves you trouble at tax time.
Pick the Tax Year
Contributions between January 1 and the April tax deadline can apply to either the current year or the prior year. Tell your custodian which one. Without instructions, most custodians default to a current-year contribution.
Label It as a Regular Contribution
When you fund the account, the custodian will ask whether the deposit is a regular contribution, a rollover, or a transfer. Choose “regular contribution” (sometimes shown as “annual contribution”). That’s how it gets reported on Form 5498, which the custodian sends to you and the IRS.7Internal Revenue Service. Form 5498 IRA Contribution Information 2025 The form separates regular contributions from rollovers, and a mislabeled deposit can prompt the IRS to ask whether you made an improper rollover.
Funding Methods
- Electronic bank transfer (ACH). Link a checking or savings account through the brokerage. Usually free.
- Check by mail. Include a deposit slip with your IRA account number and the tax year.
- Wire transfer. Faster, but one or both banks may charge a fee.
Funds generally clear within a few business days. Save your confirmation receipts to document the date and amount.
If You Contribute Too Much
An over-contribution triggers a 6% excise tax on the excess for every year it stays in the account.2Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs) To avoid the penalty, withdraw the excess plus any earnings it generated by the due date of that year’s tax return, extensions included.4Internal Revenue Service. Retirement Topics – IRA Contribution Limits Miss that deadline and you can absorb the excess by contributing less than the limit in a later year, but the 6% tax keeps accruing until the overage is gone.
